DW-series Belt Food Drying Machine Introduction

The belt type drying machine has a box-type structure. The box is provided with a single layer or multiple layers of conveying belts. The food drying machine is widely applied for mass production of continuous drying for sheet, strip pellet material with better ventilation property, especially for the materials that cannot bear high temperatures such as dehydrated vegetables, Chinese herbal pieces of high moisture content. This belt drying machine is produced by professional development engineers based on many years of practical experience. Like a hot air drying oven and microwave drying machine, the belt food drying machine is also popular in the market.

Distinctive Features of Mesh Belt Food Drying Machine

1. Special multi-layer belt design can make the materials heated uniformly and continuously which highly improves the drying efficiency.
2. The time of material staying on the belt and velocity of feeding material can be adjusted in order to obtain the best drying effect.
3. Hot air can be circularly applied, the energy is greatly saved.
4. Large capacity, high drying and thermal efficiency.
5. Low energy consumption, easy to operate and maintain.
6. Wide utilization range, many kinds of materials can be dried such as fruit and vegetable drying, traditional Chinese medicinal materials drying, food drying, industrial drying and etc..

Working Principles of Food Dryer

After the wet material is evenly fed onto the top layer of the drying belt via the belt conveyor feeding system, the moving drying belt transports the wet material to the other end and drop onto the beneath the layer of drying belt. The beneath drying belt then transports the wet material and moves in the opposite direction until dropping onto the third layer of drying belt. At the same time, hot air is evenly blown into the dryer via the bottom air distributor. With the help of an exhaust fan, the hot air penetrates the wet material on each layer of drying belt for heat transfer and take away the evaporated moisture. When the material reaches the bottom drying belt, it is dried for discharging.
