The tunnel microwave drying machine is a new type of drying equipment with high production efficiency and low operating cost. It is also an efficient and environmental friendly energy-saving equipment; especially for foods that contain bactericidal and fresh-keeping functions while drying. This equipment has been widely involved in the pharmaceutical, food, chemical, building materials and other industries.
How it works?
When the equipment running, the microwave is first generated by the microwave generator, and the feeding device is input into the microwave heater; the material is sent to the microwave heating chamber by the transmission system, and the moisture in the material is heated and evaporated under the action of the microwave energy, and the water vapor passes. The dehumidification system is eliminated to achieve the purpose of drying. The bacteria in the material are killed by the biological and thermal effects produced by the microwave electromagnetic field. Since the microwave acts directly on the material, the drying temperature is low and the speed is fast, and the loss of the active ingredient in the material is small.
The whole machine adopts modular design,and controlled by PLC system, easy operation.
2.Short processing time
Because the microwave has the penetrating property to heat the inside and outside of the material at the same time, no heat transfer medium, so the heating speed is very fast. Typically it will dry materials in one-tenth the time of the standard dryers.
3.Improve final product quality and extend its shelf-life
Microwave has the effect of disinfection and sterilization to keep product safety and extend its shelf-life.
The aqueous material easily absorbs microwaves and generates heat, so there is almost no heat loss in the heating process ensure the heating efficiency and energy saving.
The hot air in regular food dehydrators dries foods from the outside. This causes the surface to harden, making it difficult for the water inside to get out and lengthening the drying process. In contrast, the microwave drying machine uses microwaves that reach inside the food, causing the water in it to evaporate. The water vapor is carried away in air currents. This technique results in uniform drying and allows the process to be completed more quickly.
The tunnel microwave drying machine is a new type drying equipment which can dry various materials. It is suit for heating, curing and drying of raw material and products in medical, chemical, food, agricultural and sideline products, aquatic products, light industry and other industries. especially for foods that contain bactericidal and fresh-keeping functions while drying. Such as Chinese herbal pieces, extracts, powder, granules, dehydrated vegetables and so on.
