The microwave drying ejiao process is a machine and method for microwave heating of the material to be dried to make it lose moisture. The mechanical part consists of a raw material warehouse, a transmission device, a dry goods warehouse, a microwave heating device, a condenser, an evaporator, a compressor, The motor and fan structure greatly improve the drying efficiency while reducing the volume and energy consumption of the mechanical part. The condensed moisture content of 18 to 20% of gelatin is placed on a drying glue bed and placed in a microwave drying device, and the microwave energy is alternately fed, and the microwave field is superimposed uniformly and intermittently. The gelatin is heated and dried to a moisture content of 12 to 14%, Ejiao drying temperature is maintained between 35 ~ 40 °C; microwave drying device consists of drying room, anti-flow door, ventilation device, lighting device, energy-feeding components, console and detection device, Multiple groups of energy-feeding elements located in different positions in the drying room are composed of multiple sets of microwave generators and cracked antennas transmitted by microwaves. The microwave generators alternately shift the position of the microwave generator to form a radioactive sphere-shaped microwave field; the water content is greatly reduced. It is a drying cycle of 16-20% of Ejiao block, with low energy consumption and low cost, and Ejiao's production is not affected by the seasons. It can be produced all year round, greatly increasing the output of donkey-hide gelatin.
