Industrial Microwave Drying Oven | Continuous Belt-Type Microwave Dryer for Food, Wood & Chemicals
Product Overview
This microwave drying system uses volumetric heating to rapidly remove moisture from materials. Unlike conventional hot air dryers, microwaves penetrate the material and generate heat internally, significantly reducing drying time and energy consumption. The system supports customizable power output, belt speed, cavity dimensions, and exhaust settings, making it suitable for food, herbs, wood, ceramics, chemicals, and pharmaceutical granules.

Frequently Asked Questions
Q1: Can you customize the microwave dryer for sticky materials like honey or syrup?
A: Yes. We can add a customizable PTFE-coated belt and scraper discharge system to prevent sticking.
Q2: What is the maximum moisture removal capacity per hour?
A: From 5 kg/h (lab unit) up to 500 kg/h (industrial line). Please provide your moisture content and throughput for a customized quote.
Q3: Is the machine safe for continuous 24/7 operation?
A: Yes. The magnetrons are air-cooled and designed for continuous industrial duty. We offer customizable redundancy (N+1 magnetron configuration).
