NutriDryer, Industrial Food Dryer Using Microwave Technology
Our industrial microwave food dryer, NutriDryer, is a drying solution with volumetric heating for food industry professionals processing both raw ingredients and finished products.
With instant start-up and no warm-up time, our microwave systems maximize throughput, reduce energy consumption, and preserve food quality — whether used as a standalone process or as a final drying step.
Two drying systems tailored to your needs:
NutriDryer Flex: High-capacity continuous production line
NutriDryer Batch: Low-capacity or occasional processing – ideal for R&D trials
Overall, our dryer range covers processing capacities from 10 kW up to 300 kW, with moisture residual values below 10%.
Key advantages of NutriDryer, our Industrial Microwave Dryers
Fast process
The NutriDryer significantly reduces overall processing time compared to conventional drying methods
No warm-up, instant process
Unlike traditional dryers, the NutriDryer requires no warm-up time, starting instantly for maximum operational efficiency
Preservation of food quality
Taste, appearance, and nutritional values are fully preserved throughout the drying process
Patented technology
The patented technology of our pasteurizers preserves complete product and packaging integrity, without the need of holes or valves
No risk of surface overcooking
By heating products from the inside out, the NutriDryer eliminates any risk of surface overcooking
Potential decontamination during process
Depending on the product, microwave drying can contribute to decontamination during processing
Flexibility
From R&D trials to high-capacity continuous production, the NutriDryer range adapts to any processing need

- Complementary drying step, seamlessly integrated into an existing production line
- Standalone full drying solution
- Combined drying systems, integrating microwave with other technologies such as hot-air drying
Product versatibility:
This industrial microwave dryer is suitable for a wide variety of agri-food products, whether raw ingredients or finished products.
Our drying system handles diverse applications with capacities adapted to each product and process.
Capacities examples:
- Mealworms:
Flow rate: 460 kg/h
Reduced moisture from 70% to 8% (down to 2%, depending on customer needs)
- Candied fuits :
Flow rate: 150 kg/h,
Brix: from 60 °Bx to 85 °Bx
Reduced moisture from 40% to 12%
NutriDryer Batch
Low capacity or occasional processing
The NutrDryer Batch is a compact and flexible drying system, ideal for low-capacity or occasional processing. With power configurations up to 12 kW, it enables precise adjustment of drying parameters for different products and moisture targets.
Processing fexibility
- Ideal for variable production needs
- Perfect for R&D trials and process development
- Standalone full drying solution
