Chinese Cabbage Vacuum Freeze Dryer
|Place of Origin:|
1.Multi-layer box mesh belt dryer adopts the principle of multi-layer utilization of hot air and is a continuous drying equipment used in the whole batch of production;
2.The hot air provided is pure hot air. The temperature of hot air is provided according to the requirements of the goods. The temperature range is set and automatically controlled.
3.The drying box is generally a 4-layer or 5-layer structure, which is rotated in a cycle and dried layer by layer to simulate
artificial sun exposure.
4.The bottom layer is dry material, which gradually gets wet layer by layer and dehydrates layer by layer. The dry material is exposed to hot air, while the wet material is exposed to hot and humid air.
5.The articles in the multi-layer flip drying box are dehydrated and dried layer by layer, and the wet air is directly emptied from the top layer.
6. The combustion chamber of the equipment is separated and isolated from the vertical multi-layer drying box. What goes into the drying box is pure hot air without coke paste, not to mention fire hazard.
7.The fuel is widely available, wood waste, coal, natural gas, kerosene, electricity.
8. Separate design of the equipment, the drying layer is made of stainless steel, resistant to high temperature and corrosion.
Steam or electric energy is used as heat energy. The heat is generated by a steam radiator or an electric heating element. The fan conducts convective heat transfer, transfers heat to the material, and continuously adds fresh air to the oven and exhausts humid air from the oven. The oven should maintain proper relative temperature and humidity while drying. The most important feature is that most of the hot air is circulated in the drying room, which enhances the transfer of heat and mass and saves energy.
