Introduction to Grain Depot Cooling Air Fan:

With the reform of the grain circulation system and the continuous improvement of the living standards of urban and rural people, the market and consumers are more concerned about the quality of grain. The quality of grain is directly related to people's physical health and market prices, and also puts forward higher requirements for the modernization of grain reserve technology in China. Low temperature grain storage refers to the use of natural or mechanical methods to maintain the temperature of grain piles below 15 ℃ or 20 ℃ for a long time, thereby reducing the respiratory intensity of grain, inhibiting the growth of pests and microorganisms, reducing grain loss, delaying the deterioration of grain quality, and achieving the purpose of safe storage and preservation.

The development of low-temperature air conditioning for grain storage initially adopted a water-cooled unit and a terminal air treatment air conditioning system to regulate the air temperature in the warehouse, indirectly reducing the temperature of bagged grain storage, and requiring insulation treatment for the grain warehouse. However, its one-time investment is large and the cooling efficiency is low, so a cooling equipment with small one-time investment and strong maneuverability - the grain depot cooling machine - should be used.

The use of cold grain storage machines for low-temperature grain storage is an advanced and scientific grain storage technology. For grains such as rice that are not resistant to high temperatures and are prone to aging, using a grain cooler for low-temperature storage can not only quickly and effectively reduce the storage temperature, delay quality deterioration, but also compensate for the lack of mechanical refrigeration, effectively prevent the phenomenon of humidification and condensation caused by low temperature in storage, and reduce the moisture content of storage according to requirements.

Main Performance Characteristics of Grain Depot Cooling Air Fan

Adopting world-class high-efficiency fully enclosed scroll compressors with long service life and low maintenance costs, coupled with advanced high-efficiency heat exchangers, the heat exchange performance is good, the unit efficiency is high, and energy is saved.

The unit achieves energy-saving operation and ensures operational efficiency through advanced electrical automatic control, and there is no need for dedicated personnel to guard the equipment during operation. It can operate 24 hours a day, and the equipment's working condition can be automatically adjusted and corrected in real time.  

Various functional segments can be selected to purify the air and regulate temperature and humidity to meet environmental requirements. 0-100% fresh air can be introduced to maintain the freshness of indoor air, and indoor regulation and ventilation can still be achieved during transitional seasons; Through the use of self-control functions, independent adjustment of small spaces can be achieved, and maximum energy saving can be achieved.  

1. The equipment has high efficiency, significant low-temperature grain storage effect, and the hot air of the equipment is discharged upwards without being affected by environmental wind direction interference.

2. Adopting measures such as frequency conversion technology, circulating air technology, automatic loading/unloading technology of compressors, and multi node control of air volume to improve energy-saving effects.  

3. The device is easy to move and can be rotated between multiple grain warehouses, resulting in high equipment utilization.
