Introduction

The Solid-State Microwave Assisted Vacuum Dryer from Kerone is a pioneering industrial drying system that integrates next-generation solid-state microwave technology with the power of vacuum processing. Unlike conventional magnetron-based microwave dryers, solid-state microwave generators use semiconductor power amplifiers to produce highly controllable, frequency-agile microwave energy — delivering unprecedented precision in volumetric heating. When combined with a vacuum environment, which significantly lowers the boiling point of water, this system achieves rapid, uniform moisture removal at temperatures that traditional dryers simply cannot match without causing thermal damage. The result is a drying solution that preserves color, aroma, biological activity, and structural integrity in even the most delicate of materials — making it the preferred choice for high-value pharmaceutical, nutraceutical, and specialty food applications.

Why Choose Kerone Solid-State Microwave Assisted Vacuum Dryer

Kerone is one of the few manufacturers in the world to offer a commercially mature Solid-State Microwave Assisted Vacuum Dryer, and the choice is grounded in both technological leadership and application-specific expertise. Kerone’s engineering team has invested significantly in understanding the dielectric properties of diverse industrial materials, enabling the design of drying recipes that maximize energy transfer efficiency while protecting product integrity. The solid-state microwave source offers exceptional operational stability, longer service life compared to magnetron sources, and the ability to precisely tune frequency for different product loads — a capability that directly translates to higher product quality and lower rejection rates. With Kerone’s dedicated process development labs, customers receive validated drying protocols before equipment commissioning, significantly reducing scale-up risk and time to market.

Types and Features of Solid-State Microwave Assisted Vacuum Dryer

Kerone’s Solid-State Microwave Assisted Vacuum Dryer is available in bench-scale research units for R&D applications, pilot-scale systems for process development and small-batch production, and full industrial-scale continuous or batch units for high-volume manufacturing. The vacuum chamber is constructed from 316L pharmaceutical-grade stainless steel with electro-polished interior surfaces. Microwave power outputs range from 1 kW in research models to over 100 kW in industrial configurations, with operating frequencies typically at 915 MHz or 2.45 GHz. The vacuum system achieves pressures as low as 1 mbar, and integrated condenser systems capture evaporated solvents for recovery or safe disposal. Multi-zone heating and real-time moisture sensors are standard on production models.
