Industrial Automation, kick-started by Microwave and Infrared Radiation

Since after the Industrial Revolution in the 18th century, automated machines and robotics have gradually taken over the maximum share of production in many industries. Science and technology kept on progressing and finding more and more convenient solutions for reducing human labour and efforts. The results were certainly effective and successful with the decrease in manmade errors and increase in product precision. Now this transfer of control of the manufacturing industry from human workforce to the machines was eventually known as the Industrial Automation.

Industrial automation is the use of control systems, such as computers or robots, information technologies and Artificial Intelligence (AI) used to have control on different activities of an industry without critical intercession from humans and to give programmed control execution. In businesses, control techniques utilize a lot of innovations which are actualized to desired performance or output, making the automation framework most fundamental for enterprises.

Apart from providing improved productivity and advanced quality in products, automation has numerous other advantages, such as listed below –

  • Reduces Labour Fatigue
  • Prevents damage of products & materials
  • Never violates instruction set
  • Has competent inspection capabilities
  • Increases efficiency
  • Better data collection
  • Economic use of money
  • Ensures safety
  • Increases profitability
  • No personal benefit required (bonuses, perks, pensions etc.)

Automation setups can be broken down into different types –

  1. Fixed Automation – the equipment configuration is a fixed set of machines.
  2. Programmable Automation – Programs can be changed or added & deducted in the programmable devices.
  3. Flexible Automation – Equipment, programs or sequence can be changed
  4. Integrated Automation – Fully automated without any human intervention

There stands no doubt that, these hi-tech machines and automated robots are power sourced or kick-started by electromagnetic radiation, electricity or by burning of fuels and lubricants.

Vacuum Microwave Wood Drying averts cracks and discolouration

Wood Drying also known as Seasoning lumber or Wood seasoning refers to reducing the moisture content of wood prior to its use. Two main uses of seasoned lumber –
– Wood Working: used mainly as construction material as structural support to a building or woodworking objects.
– Wood Burning: used mainly for domestic or small scale commercial purposes.
Wood is divided, according to its botanical origin, into two kinds: Softwood and Hardwood. Softwoods are from coniferous trees and hardwoods from broad-leaved trees. Softwoods are lighter and generally simple in structure hence easier to process, whereas hardwoods are harder and more complex due to which permeability of hardwood is very, making it more difficult to dry. The density of softwoods ranges between 350 kg/m³ – 700 kg/m³, while hardwoods are 450 kg/m³ – 1250 kg/m³. Both consist of approximately 12% of moisture. In spite of the fact that there are around a hundred times a greater number of types of hardwood trees than softwood trees, the capacity to be dried and processed quicker and all the more effectively makes softwood the principle supply of commercial wood today.

There are two main Microwave wood drying methods namely

  1. Vacuum microwave dryer
  2. Non vacuum microwave dryer

Non Vacuum Microwave Dryer is commonly used for regular drying whereas Vacuum microwave wood dryer is a high tech and quality drying way. It is applied for high quality required and hard wood drying. Vacuum microwave dryer could rapidly evacuate dampness under a low temperature. The wood interior air has an impact on wood drying capacity. Positive air permeability has a superior drying result.
Features of Vacuum Microwave Dryer:

  • Process drying wood in confined space
  • Lower pressure to accelerate moisture movement out of wood
  • Shorter drying period compared to conventional drying
  • Maintains original wood color with minimum discolouration
  • Heat both internal and external of wood
  • Kills all kinds of insects to avoid wood mildew and other issues
  • Better drying result
  • Lower energy consumption,
  • Large capacity,
  • Suitable for expensive or high quality wood.
  • Energy saving and environmental friendly
  • Averagely drying to obtain quality wood
  • Reaches accurate water percentage, without deformation and crack

KERONE has constantly been the choice of multiple customers for its extensive ‘hands-on’ experience of application of electromagnetic radiation in wood drying industry. Demystifying the intensive process of wood drying we provide various machinery facilities and assistance to our esteemed clients as per their specific process requirement.

Efforts of Microwave and Infrared Radiation in Chemical Pulping pay off

Pulping is a procedure that separates fibrous material and cellulose from wood or other crude material as a prelude to papermaking. The reason for pulping is to free cellulose strands from other chemicals and polluting influences in the wood (or different fibrous source). Before wood can be pulped, it must experience debarking i.e. expelling bark mechanically or hydraulically and then sending the debarked wood into a chipper to cut them into small pieces ready for pulping. Pulping can be done by three processes –

  1. Mechanical – Using machines like revolving disks to prepare the pulp for paper making.
  2. Chemical – wood chips are cooked in a combination of chemical solution to remove cellulose or lignin from the wood.
  3. Semi-mechanical – a blend of mechanical and chemical.

Here we understand the process of Chemical Pulping in detail. As known it is a method of converting the wooden chips into damp pulp for paper making or processing, by cooking the wooden chips in a chemical solution to extract lignin or cellulose content which is primarily responsible for reducing paper quality and permanence. Chemical Pulping has two primary methods of processing –

  • The Sulfite process: cooks wood chips in sulfurous acid combined with limestone to produce calcium bi-sulfite. The combination of sulfurous acid and calcium bi-sulfite dissolves the lignin in the wood and liberates the cellulose fibers. Sulfite pulp is soft and flexible, is moderately strong, and is used to supplement mechanical pulps.
  • The Sulfate Process: evolved from the soda processes developed in the nineteenth century using strong bases to digest wood. Pulpers began adding sodium sulfate (correctly known as sodium sulfide) to the soda process and a significantly stronger pulp was produced. This process is more accurately known as the Kraft process (after the German word meaning ‘strength’)

Advantages of Chemical Pulping in production of paper:

  • Stronger fibre in paper
  • Highest quality printing and writing papers
  • Fewer impurities
  • Wastages can be used as fuel
  • Brighter papers produced

KERONE has always been the decision of various clients for its broad ‘hands-on’ involvement of use of microwave and infrared in the paper processing industry. Demystifying the comprehensive procedure of chemical pulping, we give different machinery facilities and help to our regarded customers according to their particular procedure requisite. Chemical Pulping is the most prominent strategy used for pulping giving the best outcomes with average yields, use of microwave and infrared radiation escalates the quality and yield result by more than 20-30%. Diminishing natural effects is likewise a critical viewpoint for any preparing industry, and thus the entirety of our hardware and arrangement improvement is centered on limiting utilities consumption and better water and vitality stewardship, decreasing the product losses and wastages produced by the procedure.

How do you make Dairy products fit for consumption?

Dairy products are basically products made from containing milk of mammals, which include food products like yoghurt, cheeses and butter among others. These products have been a part of staple food in many countries and used in traditional cuisines as well. Rates of dairy consumption vary widely worldwide. The consumption can be as high as 150kg per capita and also under 30 kg per capita in some countries.

Milk is a valuable nutritious food that has a short shelf-life and requires careful handling. Milk is highly perishable because it is an excellent medium for the growth of microorganisms – particularly bacterial pathogens – that can cause spoilage and diseases if consumed without precautions. Hence, milk processing, this allows the preservation of milk for days, weeks or months and helps to reduce food-borne illness. The usable life of milk can be extended for several days through techniques such as –

  • Clarification – particles with dense solids are separated from continuous milk phase.
  • Skimming – separation of cream from skim milk.
  • Whey Separation – separation of fat.
  • Centrifugation – process similar to clarification but more precise on particle sedimentation.
  • Pasteurization – heat treatment process to reduce the number of possible pathogenic microorganisms.
  • Fermentation – cooling to a specific temperature to influence the quality of raw milk.
  • Concentration – process of preparing products like butter, cheese and ghee with long shelf lives.
  • Preservation – process of instigating the natural inhibitors in milk (e.g., lactoferrin and lactoperoxidase) prevent significant rises in bacterial numbers for a limited period.

India in Dairy Processing:

  • Output of around 163.7 million MT, India is the largest producer of milk globally
  • India’s milk production is expected to reach 180 million MT by 2020
  • Indian dairy market is amongst the largest and fastest growing markets in the world
  • India has attained the top position in milk production globally, owing to a huge bovine population. However, the full potential of Indian milch herd still remains unattained
  • Per capita availability of milk in India has reached 352 grams per day
  • #1 in the world for production of milk
  • India’s dairy products exports is around USD 0.3 Bn in 2016-17
  • Major destinations for India’s dairy exports are UAE, Pakistan, Bangladesh, Bhutan and Nepal

The discrete choice for heating and drying solutions: Ceramic Heating Systems

Ceramic is an inorganic non-metallic solid made up of either metal or non-metal compounds that have been shaped and then hardened by heating to high temperatures. In general, they are hard, corrosion-resistant and brittle and been in use for thousands of years. We have practically been living in a ceramic world as almost every material like; Glass, tiles, pottery, porcelain, bricks, cement, diamond, and graphite, contains ceramic.
Ceramics are also called as “refractory” materials, which is a material science term that means competent of putting up with everyday abuses like extremes of temperature change, attacks from acids and alkalis, and general wear-and-tear, these properties makes the material durable, better functioning and economical. Understanding all these exceptional properties, it is also being used in various Industrial heating systems.
Ceramic heating systems, whether emitting microwave or infrared rays provide heat by sending electricity through the heating plates. As the plates get warmer, they heat up the aluminium baffles. Then, a fan blows the warm air from the baffles and into the room. One of the many benefits of using this type of heater is that it provides a constant source of heat but doesn’t get hot enough to pose a fire hazard or burn risk. Since the heating elements in this heater are completely surrounded by the ceramic parts, it is safer than most other types.
Some significant features of these Industrial systems:

  1. Efficiency and Speed – These heaters do not waste a lot of energy.
  2. Overheating Prevention and Security – Fans and thermostats inside the heaters prevent it from overheating.
  3. Convection over Radiation – These heaters work by way of convection heating.
  4. Size and Portability – Easily portable as not huge in size.
  5. Safety Features and Characteristics – able to operate at a low temperature and do not emit any poisonous fumes or chemicals.

Facts and Figures of Microwave Radiation & Heating

In the growing technology and cut throat environment for engineering, industries and demanding new and improved processing methods which can be implemented for a wider variety of materials and can yield better physical and mechanical properties of materials than conventional routes. Presently wider varieties of non-conventional processing methods are in use, but energy consumptions and processing time requirements are the main issues. Hence, Microwave radiations are found to be advantageous in terms of qualities imparted to the materials in terms of physical, mechanical, metallurgical, etc. and along with this energy and time savings during processing.
Microwave heating is a process whereby microwave rays produced by magnetrons are directed toward reactants or heating medium, which absorb the electromagnetic energy volumetrically to achieve self-heating uniformly and rapidly. These microwave rays are electromagnetic radiation and the frequency range lies between 1 and 300GHz and these microwave frequencies with different wavelengths are used for a wide variety of applications. The Federal Communications Commission (FCC), for heating purposes in industrial, scientific, and medical systems has reserved 915 MHz and 2.45 GHz frequencies. The heating by microwaves involves direct absorption of radiations by materials, then converts it into heat energy, and leads to volumetric heating of materials. The work of the authors reported that microwave heating consumes 10–100 times less energy and 10–200 times lesser processing times compared to conventional routes. Materials placed in the microwave environment are classified as insulators, conductors, semiconductors, and superconductors.

The heating prodigies are different for conventional and microwave processing of materials. Conventional processing methods involve heating the surface and then transferring heat into the materials by the phenomenon of conduction, convention, and radiation; whereas in microwave heating, the electromagnetic energy gets converted into heat from within the material, which moves toward the outer direction from the core/center of materials.
This microwave heating mechanism offers many advantages over conventional heating due to the following factors:

  • The direct absorption of microwaves by materials allows volumetric heating which produces enhanced diffusion rates, reduced power consumptions, and lower processing times.
  • These characteristics of higher heating rates and higher diffusion rates allow improvements in physical and mechanical properties of the microwave-processed materials or components owing to which defect rates are lower.
  • Further occurrence of volumetric heating provides selective heating and uniform heating, leading to decreased processing temperatures, reduced thermal gradient, reduced heat-affected zone, and lower environmental hazards.

In recent years, the utilization of microwaves in various applications has increased many folds. The various processing domains where this technology has been applied successfully are:

  • Communication systems
  • Food processing, wood drying
  • Enhanced chemical reactions
  • Vulcanization of rubber
  • Processing of ceramics and metallic materials
  • Steel making
  • Glass tempering
  • Joining of materials
  • Welding, waste treatment
  • Recovery of alternate sources of energy

To Make Stronger Ceramics Product, By Microwave Sintering

Microwave heating is a process whereby microwaves couple to materials, which absorb the electromagnetic energy volumetrically and transform it into heat. This differs from conventional methods in which heat is transferred between objects through the mechanisms of conduction, radiation and convection. As the material itself generates the heat, the heating is more volumetric and can be very rapid and selective. When applied to Ceramic materials, microwave processing opens up opportunities to reduce costs and energy consumption while improving productivity and material properties. Thus, microwave sintering techniques allows for the application of high heating rates, markedly shortening the processing time.

The possibility of processing ceramics by microwave heating was discussed over 50 years ago by Von Hippel. Since then, the results of many investigations into microwave sintering and joining of ceramics have been reported. Activity in this field began to accelerate in the late 1970s and 1980s. While most of today’s industrial microwave applications involve the relatively low temperature processing of food, wood, rubber, polymers, etc., interest in high-temperature microwave processing of materials has been growing. In recent years, microwave heating has been widely employed in the sintering and joining of ceramics. In microwave heating, a polar molecule is exposed to electromagnetic radiation at a frequency that is in the microwave range (0.3 GHz to 300 GHz). This exposure to microwave energy causes rotation in the polar molecule, which causes friction resulting in heat being generated. This phenomenon is also referred to as dielectric heating. As the heat is generated within the material and then travels to the outer surface, it saves quite a considerable processing time while keeping the surrounding temperature least affected.

Ceramic products are produced after passing through a tedious process, that being –

  1. Raw material slurry
  2. Spray Drying
  3. Shaping
  4. Heating
  5. Sintering

Microwave radiation comes in use in the last step of the process that is “sintering” which in layman’s language means heating the material so the ceramic particles stick together for better strength & longevity. Sintering is used in the manufacture of pottery and other ceramic objects. These objects are made from substances such as glass, alumina, zirconia, silica, magnesia, lime, beryllium oxide, and ferric oxide.

Advantages of Microwave Radiation in ceramic sintering:

  • Uniform heating
  • Increases Process speed
  • Acceptable chemical and physical effects
  • Selective/Volumetric heating
  • No fumes and pollutants
  • Improves reproducibility
  • Reduce wastage of heat

The microwave fast sintering appears as an alternative for the sintering and densification of ceramics with suppressed grain growth. By the reference of various researches, it is confirmed that microwave hybrid fast sintering can be employed successfully to sinter low and high dielectric loss ceramics, producing highly dense ceramics and suppressing grain growth in the final stages of sintering. Successful microwave fast sintering depends on the strict control of sintering conditions, striking an adequate balance between power and time or temperature and time to obtain highly dense and homogeneous microstructures.
In fact, the real benefit of microwave processing has less to do with the direct coupling of microwave energy to the part, and more to do with the flexibility afforded to the equipment designer.

Get the Right Heating Solution for Your Rubber Products

Microwave heating is a multiphysics phenomenon that involves electromagnetic waves and heat transfer. In a layman’s language, the material to be heated is exposed to electromagnetic waves, this passage charges up every single molecule of the material resulting in rise of temperature of the same material. This exerts pressure, which pushes the moisture in the material towards the surface which is then evaporated. Microwave heating is a commercially available method of heating liquids, suspensions, or solids in a continuous flow on an industrial scale. The pattern of microwave heat distribution depends on many physical parameters, which includes the electromagnetic field, the absorption rate and structure of the processed material, and also the dimensions of the heating container. It is also used for household purposes but on a lower scale.

Manufacturers wanting to produce new products, build new plants, or automate should consider microwave heating for their specialized heating applications. Microwave heating is a quick and efficient method of heating materials that are difficult to heat by convection or infrared methods, so there is a hike in production rates and improvement in product quality. The key parameter in Industrial Microwave Heating is uniform heat distribution. This can be achieved by different methods, which may involve computer simulation and different mechanical mechanisms such as turntables & stirrers. A proper microwave energy pattern is necessary for attaining a uniform heat release.
Conventional heating methods require heat conduction from the material’s surface inward; they are slow and inefficient for materials that conduct heat poorly. The direct and efficient heating supplied by microwave energy offers several advantages for the production of these materials. To understand Microwave heating better, let’s look at some of its advantages as listed below:

  1. Quick heat penetration
  2. Selective heating
  3. Responsive to automation
  4. Improvement in product quality
  5. Increases flexibility
  6. Combined with conventional methods
  7. High energy efficiency
  8. Space savings

Though the most widespread industrial use of microwave heating is for food processing, but it is also effective for other hard-to-heat products, such as –

  • Rubber
  • Ceramics
  • Polymer
  • Minerals & Metals
  • Waste Recycling
  • Chemicals and pharmaceuticals

New applications are emerging rapidly and gaining popularity as manufacturers discover the unique benefits of microwave heating.
In this blog, you will understand the applications of microwave heating in the Rubber Industry.

   

Microwave heating saves energy during batch preheating of rubber before setting into different product moulds. It has converted rubber vulcanization, which is required for strength and resiliency, from a batch process to a continuous one. As rubber is one of the materials that conducts heat poorly, conventional heating systems lags the process but microwave energy rapidly heats the rubber within its bulk, up to five times faster than hot air heating. Rubber is continuously extruded, microwave heated and vulcanized, and formed into products such as gaskets, tyres etc.
The Results:

  • More desirable product
  • Increased flexibility
  • Elimination of steps
  • Reduced labour costs
  • Optimum use of material
  • Less floor space
  • Saves energy
  • Safer work environment

Some Guidelines to be considered

  • Ability to exposure to microwave heat
  • Temperature of the environment
  • The optimum time of heating (not less, not more)
  • Possibility of absorbing hybrid heat treatment (microwave+ convention)

Acknowledging your cravings of the mouth watering items, KERONE has to offer Industrial Ovens of customizable sizes for various Industrial purposes. In this extract you get to know everything about a Baking Oven. Beginning with what is an Oven?
“An oven is an enclosed cavity or tunnel where dough or batter is placed amidst a hot environment and is then baked and transformed into cake, bread, cookies, or other products.”
Baking Ovens are major equipment for bakery process. In order to bake the products, Ovens use energy generation sources, e.g.: combustion of fuels (gas or oil) or electricity. The released available energy from these sources is transferred to the products by means of radiation, conduction or convection. The oven sets and maintains the proper conditions of heat, humidity, and temperature to carry out the baking process and the removal of moisture from the products to eliminate the possible existence of microbes improving the shelf life of the baked products. Meticulous baking would give us appetizing baked items with desired texture & taste.
Not only the baking ovens, but also its supplementary accessories, being circulating fan, steam extraction chimneys, safety explosion doors, fire tube, burners, temperature controller & indicators, fuel system and baking moulds are of grave importance. For the selection of baking oven various dimensions are taken into consideration such as height, width, weight, chimney size, foundation method, electrical wiring and automation. Keeping all these specifications in mind KERONE provides customizable Ovens to our valuable clients catering to their industrial requirements.
Baking Ovens are classified based on various parameters, which are the following:

  1. Physical Characteristics: Rack, Rotary Rack, Tunnel, Swing, Tray Ovens etc.
  2. Heating: Direct, Indirect, Hybrid, Convection, Radiation etc.
  3. Loading: Top or Front load
  4. Fuel Used: Diesel, Gas, Oil, Electric, Infrared
  5. Wire Bands: Articulated, Flat Steel, Modular
  6. Design: Mark III, TRP, Mark II Ovens

The type of oven that suits a bakery’s operation may be a function of production capacity, product specifications, floor space, available energy sources, operation efficiencies, construction materials, and maintenance needs.
Maintenance of ovens
Installation of excellent Ovens alone is not important but timely maintenance is also vital.
Oven maintenance focuses on two major goals:

1. Prevent food safety hazards – (physical, biological, and chemical) reducing foreign material contamination, under-processing, and contamination with lubricants. These hazards may pose a food safety risk to customers and the loss of a good reputation and money for the company.
2. Prevent equipment failures – (mechanical, electrical, and thermal) equipment failures that could have a negative impact on daily oven operations and increase downtime, triggering significant economic losses.

Indirect Dryers Outdo Direct Dryers in Drying Applications

A Rotary Dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into contact with a heated gas. These dryers are a critical component in many industrial processes, capable of processing all sorts of materials from chemicals & fertilizers to minerals & ores and nearly everything in between. The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer is inclined to slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer without opposing the gravity.

Rotary Dryers are extensively used for Drying but the following processes can be combined with it:

  • Cooling
  • Cleaning
  • Shredding
  • Separating

Features of Rotary Dryers:

  • Robust construction with various lifter (internal fins) options
  • Can be co-current or counter-current
  • Permits use of higher drying temperatures
  • Relatively long residence time
  • Highly efficient functions
  • Economic fuel and energy consumption
  • Low Maintenance cost
  • Reduced capital and operating costs
  • Huge capacity available as compared to other dryers

Rotary Dryers are majorly classified on the basis of heat transfer:

  1. Direct Rotary Dryer
  2. Indirect Rotary Dryer

Direct Rotary Dryers use direct contact between the material and drying air to scale down the moisture content of the material. Hot steam/air is circulated within the dryer, with the material being lifted up and rolled back down by a series of internal fins lined along the inner wall of the dryer. These dryers are used throughout a multitude of industries, including fertilizer and agriculture, mining and minerals, specialty chemicals, and more. They offer heavy-duty processing and consistent reliability.


But the direct dryers are at a disadvantage when assigned to dry material pigments or combustible materials as there is a risk of contamination or losing the original components of the materials. Hence the Indirect Rotary Dryers are brought into application.
