[0057] The processing method of using the microwave variable temperature and pressure difference puffing dryer to process apple crisps:
[0058] Step 1. Turn on the power, turn on the automatic control system (including PC and PLC controller), input relevant parameters and programs through the touch screen man-machine dialogue interface of the PLC controller, and press the start button to enter operation;
[0059] Start the vacuum unit 110, set the vacuum degree of the pressure tank 10 to be -0.098MPa; start the steam generator 50, set the steam temperature to 100°C; start the chiller 60, set the cold water temperature to -15°C;
[0060] Step 2. After the steam generator 50 generates steam at 100°C, the motor 220 is controlled to start, and after power is transmitted through the reducer 221, two gears, a transmission toothed belt and the hollow shaft 21, it drives the The drying cylinder 20 rotates clockwise at a speed of 15r / min;
[0061] After the drying cylinder 20 rotate...
