Cold air dryingIt is a process that utilizes the principle of refrigeration and dehumidification to forcibly circulate dry air in the food compartment, gradually reducing its moisture content to achieve dryness. Low temperature and low humidity air continuously absorbs surface moisture from food in forced circulation. The air that has reached saturation passes through the evaporator, is cooled down, and water separates out. The separated water is discharged from the reservoir through the collection tray.
Characteristics of cold air dryer:
1. Adopting a heat pump dehumidification closed cycle drying method to save operating costs; No exhaust gas or waste heat emissions, no noise pollution, environmentally friendly;
2. By adopting our patented technology of regenerative cycle heat pump dehumidification, we have expanded the application of heat pump systems in the industrial drying field. The drying performance is more than 30% energy-saving compared to ordinary heat pump dehumidification and drying, greatly saving operating costs;
3. It can achieve medium and low temperature drying (10-35 ℃), close to natural drying, with good quality, good color, high product grade, no pollution, significant energy saving, and more in line with environmental and hygiene requirements for the dried goods.
4. During the drying process, the material does not deform, crack, change color, deteriorate, oxidize, dry thoroughly, and has good rehydration properties after drying. The loss of nutrients is minimal, and the storage period is long. It is more effective than any traditional drying equipment in protecting the color, aroma, taste, individual form, and active ingredients of the dried material.
5. The closed cycle drying method is suitable for inert environment drying (nitrogen, carbon dioxide, argon, helium), and is suitable for flammable and explosive materials, harmful and toxic materials, materials with irritating odors, easily oxidizable materials, and materials that require the recovery of volatile components such as aroma;
6. PLC+touch screen fully automatic control mode, stable performance, easy operation; Adopting programmable control mode, different drying curves can be set to meet the drying methods of different types of materials;
7. In the later stage of drying (deceleration drying), it can be combined with traditional steam, electric heating, infrared, and microwave drying to shorten the drying cycle and save later operating costs;
8. Adopting internationally renowned brand matching, fully ensuring the performance of the entire unit and equipment, including valley wheel compressors, ACLO expansion valves, etc;
9. Set multiple safety protection functions: phase sequence protection, phase loss protection, overload protection, high voltage protection, low voltage protection, etc.
10. The appearance design is beautiful and elegant, and the unit occupies a small area
11. According to environmental conditions, a new air exchange energy-saving system can be implemented, which greatly saves operating costs in autumn and winter seasons
12. Unique patented energy-saving technology reduces operating costs
