The drying line uses coal, fuel, or electricity as a heat source to heat the air. Molded egg trays are dried in hot air. The temperature needs about 180220℃. If the temperature is too high, the egg tray may ignite spontaneously. The drying time is related to many factors.
The working principle is as follows: the materials are evenly distributed on the conveyor belt by the feeding device. The conveyor belt is driven by the speed regulating device to move the dried materials from the feeding end to the discharging end. The dry air is transported by the fan and passes through the material layer from top to bottom ...
