The Microwave Dryer for Drying of Chemical Powder

Microwave technology is not new in heating/drying industries, the concept of using the microwave for heating and cooking is old enough, however, the application of microwave for drying application is relatively new and gaining huge popularity with the number of features and advantages offered. We, at Kerone are amongst the first few organizations that had started advocating about the advantageous application of microwave drying systems either as supporting systems or full-fledged systems.

What is microwave drying? In simple, words microwave dryers are the dryers that utilize microwave energy, produced by the cavity magnetrons in the form of high-speed electromagnetic waves. When these waves collide with the water molecules within material it energies them and result in the production of heat in very less time. This process of heat generation had gained huge popularity since it generates a massive amount of controlled heat with very lesser input. The amount of heat dissipated is easily controllable with the use of microwaves.

Chemical industries are also not untouched with the advantages that microwave bring in however the adoption rate has been slow due to the nature of chemical material being dried, Chemical powders are temperature sensitive thus, drying situations are primarily dictated by rigorous quality standards. The powder drying process requires liquid or slurry material to be drying through applying heat so that it changes its form and converts to powder by losing water in evaporation.

The chemical powder drying process is usually the last step before it being packed. Most chemical powders are temperature sensitive, hence it required to dry at a lower temperature to avoid degradation. Kerone’s microwave drying system helps to overcome this problem by reducing the moisture content at a lower temperature (80-90°C)without harming any product quality.A significant reduction in drying time in microwave drying is often accompanied by an improvement in product quality, making it a promising drying technology. About,95% of the surfaces of the machine are made of stainless steel. It adopts advanced technologies such as a PLC control system, temperature control system, camera monitoring system, automatic feeding system, and other high-end technologies used.

Feature of Microwave chemical dryer developed by Kerone:

  • High-Quality Magnetron manufactured by Panasonic(Japan)/IBF(Germany)/Hitachi (Japan).
  • PID Indicator/controller
  • RF/MW choke/timer provision
  • Stainless steel chamber
  • Required electrical & thermal safety features for microwave generator
  • Variable frequency (Belt speed control)
  • Variable Power output (selectable) up to 100%
  • Temperature Control

  • Design that helps for safe and easy operation and maintenance.
  • Minimized radio field leakage, made to international standards.
  • Pre-programmable Timer on the display for added ease and to avoid losses due to excess heating.

Advantages of using Microwave:

  • The microwave heating process is clean and no emission of any gases or residuals.
  • Microwave heat penetrates both on the surface as well as internally within the object placed for the Treatment.
  • The high speed of heating reduces the total time of processing.
  • The microwave heating process is highly controllable.
  • The workspace requirement is very less.
  • Best drying results are achieved as healing takes place from within the material.
  • The cost of production with microwave dryers are lesser than airflow or direct heat transfer based dryers.
