Principle

The air dryer utilizes the inverse Carnot principle to absorb heat from the air outside the insulation room and transfer it to the inside, thereby increasing the temperature of the insulation room and cooperating with corresponding equipment to achieve material drying. During the working process, the heat pump evaporator absorbs heat from the outside air or recovers the waste heat discharged during the drying process. The energy is transferred to the insulation room through the compressor, and the hot air in the insulation room is repeatedly circulated and heated. The heat is added to the material through hot air, causing the surface moisture of the material to evaporate. The moisture in the material is then discharged through hot air or condensation drainage, ultimately achieving continuous drying of the material.

Product Advantages

Safety and Environmental Protection: There are no safety hazards such as explosions, electric leakage, oil leakage, and gas leakage, and zero pollution emissions to the environment. Greatly save operating costs.

Efficient and energy-saving: It does not require any electrical assistance to produce high-temperature hot air below 80 ℃ for drying items. The operating cost is 30%~70% more energy-efficient than other hot air drying equipment. According to the characteristics of the drying process, new air pre dehumidification, exhaust heat recovery and other technologies can also be used for better energy-saving effects.

Better drying quality: Air drying is a gentle drying method that is close to natural drying. The evaporation rate of surface moisture is similar to the internal migration rate to the surface, ensuring good quality, good color, high product grade, and no pollution of the dried items.

24/7 operation: regardless of adverse weather conditions such as spring, summer, autumn, winter, rainy weather, or nighttime, it can work continuously 24 hours a year.

Accurate control of drying temperature and humidity: The highest drying temperature can reach 80 ℃, meeting the requirements of different drying processes. Equipped with a self-developed dedicated controller, different material drying programs are set according to the drying process to achieve intelligent drying without the need for human supervision.

Safe and durable: Compared to traditional drying modes, it takes up less space and is easy and fast to install. It uses high-quality high-temperature heat pump compressors from foreign brands, patented high-efficiency condensers, and advanced refrigeration system design. Multiple effective measures are taken to reduce the compressor exhaust temperature and compression ratio, extending the service life of the host.

Economic benefits comparison between air source dryer and other heat source drying equipment

Compare and calculate based on the average dehydration of 1 kilogram under the same working conditions with a temperature of 65 ℃ in the insulation room. The latent heat of vaporization of water is 560 kcal/kg. During the dehydration process, the evaporation of water requires about 60% -70% of the total heat required during the drying process. Therefore, drying 1 kilogram of water requires a total of 800 kcal of heat.

Scope of Application

Seafood, various agricultural products, soft packaged food bags, snack foods, dates, nuts, goji berries, apple slices, raisins, banana slices, preserved fruits, okra, and deep processing of Chinese herbs.
