Microwave drying and sterilization provides an efficient solution for seasonings and spices. With fast and uniform heating, it can effectively remove moisture and reduce microorganisms while shortening processing time and improving production efficiency. The system can also be customized for different seasonings, spice powders, moisture levels, and production requirements.
Our industrial continuous microwave dryer and sterilizer provides an efficient drying and sterilization solution for seasonings and spices, including chili powder, pepper, cumin, spice blends, seasoning powders and other food ingredients. Microwave energy generates heat directly within the material, enabling rapid and uniform moisture removal while helping reduce microbial levels, shorten processing time and improve production efficiency. The system can be customized with different microwave power levels, conveyor speeds, temperature settings and control functions according to the material properties, initial moisture content, sterilization requirements and target processing capacity.

This air-cooled tunnel microwave dryer is designed for continuous industrial processing. Using microwave volumetric heating, it heats materials from the inside, enabling efficient and consistent drying throughout the production process.
The equipment is constructed from 304 stainless steel and uses air-cooled magnetron units for reliable operation. Its PLC control system allows independent adjustment of microwave power and conveyor speed in different sections, making it suitable for stable, standardized, and continuous production in industrial facilities.
Fast Drying and Sterilization
Microwave energy heats the seasoning directly, allowing moisture removal and microbial reduction to take place quickly and significantly shortening processing time.
Uniform Heating
Microwave energy penetrates into the material and provides volumetric heating, helping reduce uneven drying and improve product consistency.
Drying and Sterilization in One Process
Moisture reduction and microbial control can be achieved in the same continuous process, simplifying the production line and improving processing efficiency.
Better Product Quality
Shorter processing times help reduce prolonged heat exposure, which is beneficial for maintaining the color, aroma and overall quality of spices and seasonings.
Continuous Industrial Production
The conveyor-type design enables continuous feeding and discharging, making the system suitable for industrial-scale seasoning and spice processing.
Adjustable Processing Parameters
Microwave power, conveyor speed, processing time and temperature can be adjusted according to different seasoning materials and production requirements.
Easy Operation and Process Control
The system can be equipped with PLC and touchscreen control for convenient parameter setting, operation monitoring and recipe management.
Customizable for Different Products
The equipment can be customized according to the type of seasoning, initial moisture content, target moisture level, sterilization requirements and required production capacity.
