Before entering the drying chamber, the vegetables are preheated in the feeding cylinder and enter the drying chamber. The vegetable drying tray vibrates under the drive of the vibrating motor, which improves the temperature of the hot air and microwave heat. The uniformity in the vegetables makes the vegetables dry quickly and meets the requirements of the water content of the vegetables. The dried vegetables are output from the discharge cylinder.

There is an air inlet fan at the mouth of the air inlet pipe, and an infrared disinfection lamp Ⅰ is installed in the air inlet pipe between the air inlet fan and the heater to ensure the air volume of the air inlet pipe and to sterilize the air entering the air inlet pipe to avoid Vegetables are contaminated.

A cooling device is provided on the discharge cylinder, and the cooling device includes a cold air pipe and a cooling fan, and an infrared disinfection lamp II is arranged in the cold air pipe.

There is a vegetable toggling frame above the vegetable drying tray in the drying room, and a toggling bar is arranged on the vegetable toggling frame. The vegetable toggling frame is fixed on the side wall of the drying room through a fixing frame, and the vegetable toggling frame is controlled up and down by a slider. During the vibration process, the vegetables are constantly moved by the toggle bar, which further speeds up the drying speed and provides drying efficiency and drying uniformity.

Compared with the prior art, the utility model has the advantages of: the hot air-microwave vegetable drying equipment of the utility model, the exhaust hood collects the waste heat in the drying room, and transports it to the feeding cylinder through the air outlet pipe, and preheats the vegetables first. , Improve the utilization rate of heat, the vegetable drying tray vibrates under the drive of the vibrating motor, which improves the uniformity of hot air and microwave heat in the vegetables, thereby improving the drying efficiency and ensuring that the moisture content of the vegetables meets the requirements.
