In the field of grain storage in China, high temperature and high humidity environments often lead to problems such as grain heating, mold growth, and pest infestation, directly affecting the quality and safety of grain storage. As a mobile refrigeration equipment designed specifically for domestic storage environments, the Dongfu brand grain cooler has become a key solution for achieving green low-temperature grain storage through precise temperature and humidity control technology. Its core function is to convert the ambient air into a constant temperature and humidity airflow that meets the characteristics of grains after cooling and humidity regulation, and directly deliver it to the interior of the grain pile, effectively solving the pain points of low efficiency and high energy consumption of traditional ventilation methods.

1、 Cooling capacity of full warehouse coverage

The Dongfu grain cooler can be adapted to various types of warehouses such as vertical silos, shallow round silos, and flat warehouses to meet the low-temperature storage needs of different scale grain depots. The equipment adopts air circulation treatment technology, which cools the inhaled air to5-18℃Humidity control within75%Next, it will be sent to the bottom of the grain pile through the ventilation duct. Low temperature air forms a negative pressure circulation in the grain layer, gradually spreading upwards to achieve uniform cooling of the entire grain pile. Experimental data shows that the temperature of the grain pile processed by this device can be stably reduced to15℃Below, the humidity is controlled within a safe range, effectively suppressing the respiration of grain and delaying the aging rate.

2、 Grain storage guarantee for multi scenario applications

The equipment provides emergency solutions for special storage scenarios such as high moisture grains and heat generating grains. During the high temperature period in summer, traditional ventilation methods can easily lead to grain piles“Cold heart and hot skin”Phenomenon, and the Dongfu grain cooler can accurately eliminate local hot spots through horizontal ventilation design. For example, in the application of horizontal ventilation in a bungalow warehouse, the split typeGLA85dThe series of models separates the refrigeration unit from the suction system to reduce cooling loss and improve efficiency21Energy efficiency improvement of wheat storage in warehouses below rice level30%In addition, the equipment is suitable for low-temperature storage of high-quality rice, and the processed rice has a processing quality close to that of fresh grains, resulting in an increase in the unit price of outbound sales60yuan/Ton.

3、 The energy-saving advantages of intelligent control

Equipment equippedPLCProgrammable Control Systems and7Large screen human-machine interface, supporting air outlet temperature（7-18℃）Humidity（40-85%RH）It has precise settings and features power-off memory and fault self diagnosis. Variable frequency control technology can automatically adjust the fan speed according to changes in the temperature of the grain pile, achieving energy savings compared to fixed frequency equipment25%. In a certain way3.5Taking the 10000 ton rice reserve warehouse as an example, adopting this equipment reduces the annual storage cost10.4Ten thousand yuan, to avoid food loss and economic losses45Ten thousand yuan, while extending the storage period2-3In the year, the comprehensive economic benefits were significant.

Dongfu brand grain cooler deeply integrates refrigeration, ventilation, and self-control technologies through technological innovation, providing efficient, energy-saving, and intelligent grain storage solutions for the grain storage industry, and helping to fully implement China's grain security strategy.
