Frequently Asked Questions (FAQ)
Microwave systems operate at higher frequencies (915 MHz or 2450 MHz) and are ideal for surface and thin-layer heating, while RF systems at lower frequencies (27–40 MHz) offer deeper penetration into thick or dense materials for uniform processing.
Yes, all Kerone microwave systems include multiple safety interlocks, electromagnetic shielding, and leakage detection systems that comply with international safety standards such as CE and IEC.
Plasma systems can treat a wide range of substrates including polymers, metals, glass, ceramics, and composites for applications like surface cleaning, activation, etching, and thin-film deposition.
Kerone designs inline and batch configurations for microwave, RF, and plasma systems that can be seamlessly integrated into existing manufacturing workflows.
Microwave systems deliver energy directly to the material, reducing heat-up times by up to 70% and lowering total energy consumption compared to convective drying methods.
Yes, Kerone has dedicated R&D facilities where customer materials are tested using pilot-scale microwave, RF, and plasma equipment to validate process parameters before full system design.
Kerone offers atmospheric plasma (DBD and corona discharge) for web and surface treatment and vacuum plasma systems for precision etching, deposition, and sterilization applications.
Yes, Kerone integrates PLC/SCADA-based automation with remote access capability, allowing operators to monitor and adjust system parameters from a central control room or mobile interface.
Microwave drying improves product quality by enabling rapid, uniform moisture removal without surface case hardening or thermal degradation. Since energy is generated inside the material, internal moisture migrates outward evenly, reducing cracking, warping, and discolouration. For food products, this means better retention of flavour, colour, and nutrients. In pharmaceutical applications, microwave drying prevents polymorphic changes and preserves API activity. Kerone's microwave dryers incorporate precise power control and temperature monitoring to maintain consistent product quality across batches.
Radio Frequency (RF) drying operates at 13.56 MHz or 27.12 MHz and penetrates materials up to several inches deep, making it ideal for thick or dense products that conventional drying cannot reach uniformly. Key industrial applications include post-bake drying for biscuits and snacks, textile drying and heat setting, glueing and bonding in wood processing, pharmaceutical granule drying, and rubber vulcanization. Kerone's RF drying systems offer precise power density control, automated electrode gap adjustment, and energy-efficient operation, making them suitable for both continuous and batch processing.
Achieving uniform heating in microwave systems requires careful system design, including multimode cavity design, mode stirrers or rotating turntables, optimized antenna placement, and power modulation techniques. Kerone engineers design industrial microwave systems with computational electromagnetic modeling (CEM) to ensure even field distribution for the specific load geometry. Conveyor speed, product layer thickness, and microwave power level are calibrated during trials. Hybrid microwave-hot air designs further promote temperature uniformity by using convective air to equilibrate surface temperatures.
Continuous microwave drying systems use conveyor or tunnel configurations to process materials at high throughput rates, making them suitable for industrial-scale production. Kerone's continuous microwave dryers feature modular design for scalability, stainless steel construction, adjustable belt speeds, integrated moisture sensors with feedback control, and energy-efficient magnetron configurations. They are used in food processing, ceramics, pharmaceuticals, chemicals, and wood products. Continuous systems are significantly more productive and energy-efficient than batch microwave systems for large-scale applications.
Microwave and RF processing systems from Kerone deliver measurable advantages across a broad range of industries. In the pharmaceutical sector, they accelerate granule drying and API processing while preserving active compound integrity. The food and nutraceutical industry uses them for rapid drying of snacks, spices, herbs, and instant beverages without compromising flavor or nutrition. Rubber and polymer manufacturers benefit from faster, more uniform vulcanization and curing. The textile and paper industries rely on RF drying for precise moisture profile correction across wide fabric and paper webs. Ceramic and advanced material producers use microwave sintering to achieve uniform densification at lower temperatures. Across all sectors, the common benefits are faster processing, lower energy consumption, and superior product quality versus conventional thermal methods.
Kerone's industrial microwave systems are available in power configurations ranging from 1 kW for laboratory and pilot-scale units up to 200 kW and beyond for large-scale continuous production systems, with multiple magnetron or solid-state sources combined to achieve the required power density. RF systems typically operate at ISM frequencies of 13.56 MHz or 27.12 MHz, with power outputs ranging from 5 kW to 300 kW depending on the application and electrode configuration. System power is not selected arbitrarily, Kerone's engineers conduct thermal load calculations based on the material's dielectric properties, throughput rate, and required moisture reduction to specify the exact power needed for efficient, cost-effective operation.
While microwave and RF systems primarily deliver volumetric thermal energy to heat or dry materials from within, plasma systems operate on a fundamentally different principle: they generate a highly energized state of ionized gas (plasma) that chemically and physically modifies material surfaces without bulk heating. Plasma treatment is used to enhance surface adhesion, wettability, and bonding in materials such as films, foils, polymers, composites, and textiles – applications where thermal processing would cause damage. Kerone offers atmospheric and low-pressure plasma systems for surface activation, cleaning, coating deposition, and sterilization. In practice, the three technologies are often complementary: microwave or RF drying handles the bulk of the process, while plasma treatment handles surface finishing or functionalization in the same production line.
