Continuous Tunnel Microwave Dryer for Bulk Foods & Herbs – Customizable Power (12-200kW) & Conveyor Speed

This customizable industrial microwave dryer uses microwave electromagnetic energy to volumetrically heat and dry materials, achieving rapid, uniform moisture removal. Available in continuous tunnel, vacuum low-temperature, and multi-layer industrial configurations.

Unlike conventional drying that relies on thermal conduction (which is slow for insulating materials), microwaves selectively interact with polar molecules (primarily water), generating heat within the entire volume of the material simultaneously. This enables drying times 30-90 minutes compared to 24-48 hours for freeze drying, and energy consumption of 1-1.5 kWh per kg of water removed—up to 90% less than traditional methods.

The system is fully customizable in microwave power, conveyor speed, drying zone configuration, and control logic. It is suitable for continuous 24/7 operation and can be integrated with upstream/downstream equipment to form a complete production line.

• Food industry: Drying fruits, vegetables, nuts, tea, herbs, spices, meat jerky, pet food
• Pharmaceutical: Drying pills, capsules, tablets, Chinese medicine extracts, healthcare products
• Chemical materials: Powders, granules, pigments, catalysts, rubber additives
• Wood & building materials: Wood sheets, lumber, MDF, water-based paint drying
• Agricultural products: Grains, beans, peanuts, chili, flowers
• Textile & tobacco: Yarn, cotton, tobacco leaf drying

This microwave dryer is highly customizable to meet your specific production requirements:

• Microwave power: From 3kW to 200kW+ - customizable based on throughput and material moisture content
• Conveyor width & length: Customizable to match your product dimensions and facility layout
• Belt material: Teflon conveyor belt (food-grade) or stainless steel mesh - customizable
• Number of drying zones: Modular sections can be added or removed - customizable
• Temperature & humidity control: Precise settings via PLC with infrared thermometry - customizable
• Cooling system: Air-cooled or water-cooled magnetrons - customizable
