Grain Coolers Designed for Grain Storage Environments

Grain cooler is a kind of cooling equipment specially designed for grain storage environment, aiming to inhibit the respiration of grain, reduce grain loss, and safeguard the quality of grain by controlling the temperature inside the grain silo efficiently and accurately. It is widely used in grain silos, grain storages, grain processing plants and other places, and is one of the important equipments for modern grain storage management.

The role of grain cooler

Temperature control: reduce the temperature inside the grain silo and inhibit the respiration of grain by cooling the air.

Humidity regulation: maintain the appropriate humidity inside the grain silo to prevent mold and mildew of grain.

Reduce loss: Reduce the loss of grain due to respiration, pests and mold by controlling temperature and humidity.

Guarantee quality: maintain the freshness and nutritional value of grain and extend the storage time.

Working Principle

Air cooling:

The grain cooler draws in air from outside the silo.

The air is cooled down by a cooling system (e.g. evaporator).

The cooled air is fed into the silo and evenly distributed into the grain pile.

Circulation Ventilation:

Cold air flows through the grain pile and absorbs the heat generated by the grain.

The hot air is discharged from the silo, creating a circular ventilation that continuously reduces the temperature of the grain pile.

Humidity control: By adjusting the dehumidification effect in the cooling process, the appropriate humidity is maintained in the grain silo.

Advantages of Grain Cooler

Efficient cooling: quickly reduce the temperature of the grain silo and inhibit the respiration of grain.

Precise control: the temperature and humidity can be precisely controlled according to the type of grain and storage requirements.

Energy saving and environmental protection: adopting high efficiency compressor and frequency conversion technology to reduce energy consumption.

Uniform ventilation: Ensure uniform distribution of cold air, avoiding localized overheating or overhumidity.

Extend storage time: effectively maintain the quality of grain and extend the storage cycle.

Application Scenarios

Grain warehouse: used for temperature and humidity control of large grain storage warehouses.

Grain depot: applicable to national reserve grain depot and local grain depot.

Grain processing plant: for raw material storage and finished product storage.

Seed warehouse: to provide constant temperature and humidity environment for seed storage and guarantee seed vitality.
