The scallion 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 scallion, and the hot and humid air in the drying room is directly discharged to the outside of the drying room through the dehumidifier.
The scallion heat pump dryer can quickly remove the water in the scallion without affecting the original color, shape and nutrient content of the scallion. The scallion 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.
One set scallion drying machine contains:
1:Heat pump drying host
3:Fan frame with fan
4:Trolley with tray
The drying chamber is used 100mm polyurethane insulation board, supporting 304 stainless steel trolleys and trays.
Advantages of the scallion dryer:
Application of the scallion dryer:
The heat pump dryer can be used in many application, like agriculture, industry, seafood, grain, herbs, construction, paper products, seasoning, mineral industry, etc.
1:Dry vegetables: radish, lettuce, pumpkin, carrots, spinach, cassava, etc.
2:Dry fruits: like apple, lemon, mango slices, peach, apricot, etc.
3:Dry meat: like sausage, beef, duck, ham, etc.
4:Dry seafood: fish, shrimp, seaweed, etc.

1: Pick scallion
Due to the different quality and maturity of scallion, unsuitable scallion should be selected before drying.
2: Clean the scallion
To clean the surface dust of scallion, if the output is large, it is recommended to use a professional scallion cleaning machine.
3: Scallion slice
Scallions need to be sliced.
4: Put the scallion on the tray
Spread the scallion evenly on the tray with a thickness of about 5 cm, and then put them in the drying oven.
5: Scallion drying
Set the temperature in the drying room to 65°C and the humidity to 10%. Dry for 6~8 hours to complete the scallion drying.
The dried scallion will regain moisture when they are in direct contact with the air, so a sealed package is required. If you use vacuum packaging, you can better preserve the color and aroma of scallion.
