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.

Compared to traditional air-drying methods, food air dryers are much more efficient in removing moisture from food products. Traditional air drying can take up to several days, whereas a food air dryer can complete the process in a few hours. This means that with a food air dryer, you can have dried fruits, vegetables, meats, and other food items in just a matter of hours, instead of waiting for days or weeks.

High-temperature food dehydrator fruit and vegetable dryer can dry the moisture on the surface of the food and retain its original color and taste. The machine is made of high-quality stainless steel, which is anti-corrosive and beautiful. The PLC touch screen control panel is used to easily adjust the temperature and time to accurately grasp the best state of food drying.

The refrigeration drying chamber implements the process: employing air with decreased temperature and humidity, accomplishing a compelled circulation among materials, gradually decreasing materials' moisture content to attain the mandated level. During the enforced circulation, the decreased temperature and humidity air continually soaks up moisture from the exterior of materials, the saturated air travels through the evaporator, as a result of the refrigerant's evaporation, the evaporator's surface temperature falls below the ambient temperature. The air cools, the moisture is removed, then the removed moisture is expelled by the water collector. The decreased temperature and humidity air then reenters the condenser, where the air is heated by the elevated temperature gaseous refrigerant from the compressor, resulting in dry air, which subsequently blends with the saturated air to generate decreased temperature and humidity air, conducting repetitive circulation. Materials dried by the refrigeration dryer not only uphold their original quality, but also are more convenient for packing, storing, and shipping.

Should the vent be left open or closed while dehydrating?

Leave the vent closed if you are only using one tray to dehydrate. lf using more than one tray, be sure to leave the ventopen during the dehydrating process.
