Onion drying machine introduction

Working principle of onion drying machine

The onion heat pump dryer adopts the principle of reverse Carnot cycle. It absorbs low-temperature heat energy in the air, and becomes high-temperature heat energy after efficient heat collection and integration of the heat pump system, which is transported to the drying room to circulate heating and drying the onion, and the hot and humid air in the drying room is directly discharged to the outside of the drying room through the dehumidifier.

The onion heat pump dryer can quickly remove the water in the onion without affecting the original color, shape and nutrient content of the onion. The onion drying oven is equipped with a computer control system, which can realize automatic temperature control. The drying temperature range of the heat pump dryer is 20-80°C, and the materials suitable for drying are very wide, such as grains, edible fungi, medicines, seafood, bacon, fruits and vegetables, tobacco leaves, seeds, spices, etc.

Components of onion drying machine

One set onion drying machine contains:
