In drying process, fresh cold air is sucked into the drying chamber by the circulation fan and flows through the steam radiator or electrical heating tubes installed at the top to get required temperature. With the help of air distributor, the hot air evenly flows through each layer of trays for heat transfer and carries way the evaporated moisture. Most of the damp air flows back to the circulation fan for next drying circulation while part of the damp air is exhausted for energy saving. The drying process is batch type. When the drying is finished, open the chamber door and pull out the trolleys for unload the dried product.
