Compared with the box type and vacuum microwave drying equipment, the tunnel type microwave drying equipment has the main advantages of continuous drying, large production and low labor intensity. Compared with the traditional equipment has the advantages of high efficiency, low energy consumption, the uniform heating, the drying speed is fast, the thermal inertia, the safety and environmental protection, the advantages of simple operation, easy to control etc.. The power of this device is between 30 kW and 200 kW. It is suitable for dry products with water content below 30%. The products with too high water need to focus on the cost of drying.
Weiyasi tunnel type microwave drying equipment with chain type microwave drying equipment, cloth type microwave drying equipment and net belt type microwave drying equipment three, chain plate commonly used in dry weight of large objects, cloth bag type is used to dry powder and paste material two, mesh belt is mainly used to dry bulk and granular. Material.
Vacuum Freeze Dryer
The vacuum freeze drying technoloLD, which is also called sublimation drying, is a technical method
that freezes the samples in advance, and then sublimates its moisture in vacuum state.
