Principle: The hot air drying box adopts a rotary heating device, which can generate a large amount of hot air in a short time. It can kill insect eggs through high temperature treatment and completely solve the discoloration phenomenon during drying. The drying box adopts metal aluminum inner wall plate, silica gel cotton insulation, corrugated color steel plate or aluminum alloy outer wall plate. The box adopts digital control and detection, so that the air circulation and humidification, heating is effectively controlled.

1, the use of a unique insider type cold trap, simple structure, practical.
2. Cold trap working temperature ≤ 40 ℃ (optional ≤ 60 ℃, ≤ 88 ℃).
3. The refrigeration system adopts famous brand compressor, which has large cooling capacity and low energy consumption.
4. The vacuum series is safe and reliable, and the working vacuum degree is high.
5. The heating and drying process is automatically controlled, the heating temperature fluctuation is small, and the control is precise.
6. The moisture content of the product can be as low as 1 ~ 3%, while maintaining the color, aroma, taste and nutritional ingredients of the original, and the shelf life is long.
