Cold air dryer working principle

The cold air dryer uses the low temperature and low humidity air to force the circulation between the foods, so that the water content of the food is gradually reduced and dried. The cold air drying system utilizes the principle of low dew point dehydration to forcibly circulate dry air to the drying room to gradually reduce the water content to a dry process. The low-temperature and low-humidity air continuously absorbs the surface moisture of the food in the forced circulation, and the saturated air passes through the evaporator, is cooled and precipitates water, and the precipitated water is discharged from the storage body by the water collecting tray. The cold air drying system is a special processing method for simulating the natural natural air drying environment in the warehouse, low-temperature low-humidity, high wind speed to quickly dehydrate and dry the materials, and at the same time forming flavor.

Cold air dryer product advantages:

1. The internal circulation low-temperature dehydration technology is adopted to dehydrate, shape and dry the articles in one time, which saves energy compared with the drying method of traditional hot air drying and moisture removal.

2. Forced circulation, so that the temperature difference between the upper and lower sides of the cold air drying warehouse is small, and multiple fans are circulated, and the temperature and humidity in all corners of the warehouse are even.

3. Cold air drying warehouse dedicated circulation fan to ensure uniform drying, uniform color, no salt return, no need to repeat washing.

4. The temperature of the cold air drying library is controlled automatically, and the humidity is controlled automatically to ensure the proper temperature and humidity for drying.

5. Drying the computer board temperature and humidity automatic control and display, truly realize automatic management, no need to be on duty.

6. Drying quickly, using imported compressor circulating dehydration treatment, energy saving, high yield.

7. It is dried at a low temperature of 5 °C - 40 °C. During the drying process, the material is not deformed, cracked, discolored, no deterioration, no oxidation, thorough drying, good rehydration after drying, less loss of nutrients, and long storage period. Protects the color, aroma, taste, individual form and active ingredients of the dried product more effectively than any conventional drying equipment.

8. It is found in air drying applications below 15 °C, which is beneficial to the fermentation of materials in low temperature environment, and greatly contributes to the flavor formation and toughness of air-dried materials.

9. The system has low noise, stable operation and low operating cost. The heat pump heat recovery system is used, which is more than 50% energy saving than the traditional heat pump method.
