Microwave Tunnel Dehydrator
Microwave Tunnel Dehydrator is a high-efficiency solution for continuous dehydration of food and agricultural products. Leveraging microwave energy, it generates heat via dielectric heating—penetrating materials to evaporate moisture from the core outward—ensuring uniform dehydration while cutting processing time by 30%-70% compared to traditional methods. Constructed with food-grade stainless steel (304/316L), it meets FDA/USDA hygiene standards, and features PLC/HMI automated control for precise parameter management. Ideal for vegetable drying, meat processing, seafood preservation, and more, this equipment delivers energy savings, consistent quality, and scalable throughput, making it a reliable choice for global food manufacturers.

Product Details
Working Principle
The Microwave Tunnel Dehydrator utilizes dielectric heating: as materials move through a sealed microwave tunnel on a continuous conveyor belt, 2450MHz microwave energy penetrates the product, causing water molecules to rotate rapidly and generate frictional heat. This heat evaporates moisture from the interior to the exterior, achieving efficient dehydration. The tunnel’s sealed design prevents microwave leakage (<5 mW/cm², compliant with CE/UL safety standards).
Features
High Efficiency & Energy Savings:
Directly targets water molecules, reducing dehydration time and energy consumption vs. hot air drying (30%-70% faster).
Uniform Results:
Microwave penetration ensures consistent moisture removal, preserving texture and nutrition.
Automated Precision:
PLC/HMI controls allow customized adjustment of microwave power, temperature, and conveying speed.
Hygienic Design:
Food-grade stainless steel construction (304/316L) meets FDA/USDA standards, with easy-to-clean surfaces (CIP-compatible).
Scalable Throughput:
Continuous tunnel operation supports industrial-scale production (100-1000 kg/h, model-dependent).
Technical Highlights
Microwave Generation:
Uses magnetrons (cost-effective, high-power) or solid-state sources (stable, precise control).
Process Control:
Infrared/pyrometric sensors monitor temperature, with automatic power adjustment for stability.
Safety & Compliance:
Interlock doors, emergency stops, and insulated design (minimizes heat loss) meet global safety standards.
Energy Optimization:
Optional waste heat recovery (e.g., preheating air) further enhances efficiency.
Application Fields
Primarily used in the food industry:
Fruits & Vegetables: Drying mango, banana, spinach, onions for snacks or ingredients.
Meat & Seafood: Producing jerky, dehydrated fish cakes, and shellfish.
Seasonings & Ingredients: Drying spices, soup bases, and instant noodle seasonings.
Agricultural Products: Processing herbs (rosemary, lavender), medicinal materials, and seeds.
This equipment combines advanced microwave technology with robust construction, delivering efficient, uniform dehydration for diverse applications in global food and agricultural sectors.
