Grain Cooling Solution

Hisurp’s Low Temperature Grain Cooling Solution is designed for grain depots and agricultural storage facilities that require a stable 10–15°C low-temperature storage environment. It is developed for customers seeking a more advanced grain preservation method to suppress insect activity, reduce mold risk, maintain grain freshness, and support green storage management.
In long-term grain storage practice, low-temperature storage has proven to be an effective way to stabilize grain condition, reduce storage costs, and improve final grain quality. Hisurp’s low temperature grain storage air conditioner is specially built for this purpose, offering a solution beyond conventional warehouse air conditioning.

Why Low Temperature Storage Matters?

Stored grain is not an inactive material. Even after harvest, grain continues to respire. When storage temperature is too high, respiration, pest development, and quality deterioration become more active. Keeping grain at lower temperature can significantly improve storage safety and value retention.

Key advantages of low-temperature grain storage include:

  • Suppression of grain respiration
  • Inhibition of insect growth and reproduction
  • Reduced mold activity
  • Slower fat oxidation and starch degradation
  • Lower need for chemicals and fumigation
  • Improved grain processing quality
  • Better retention of taste and freshness

For many grain storage projects, maintaining a stable 10–15°C warehouse environment is an effective long-term preservation strategy.

Product Features of Grain Cooling Solution

Designed for 10–15°C Storage Control

Designed for 10–15°C Storage Control

This unit is specially developed for low-temperature grain storage, helping operators maintain grain warehouse temperature in the range typically required for long-term preservation. The structure design and operating control logic are adapted for this low-temperature application.

Special Heat Exchanger for Low-Temperature Operation

Special Heat Exchanger for Low-Temperature Operation

The heat exchanger uses a low-density, wide-fin-spacing design, which helps reduce the risk of frosting during low-temperature operation. This is important because grain storage cooling often requires long-running, stable low-temperature performance.

Timed Defrost Mode

Timed Defrost Mode

To support dependable operation, the system adopts a timed defrost mode. Frost on the heat exchanger surface can be removed at scheduled intervals, helping maintain heat transfer efficiency and stable cooling output.

High Sensible Cooling to Reduce Moisture Loss

High Sensible Cooling to Reduce Moisture Loss

Like other Hicon grain storage air conditioners, this low-temperature model is designed with a high sensible heat ratio. This helps prioritize air temperature reduction while minimizing excessive dehumidification that may cause unnecessary grain moisture loss.

Intelligent Temperature Control

Intelligent Temperature Control

Through precise operational management, the unit can help achieve gradual cooling and stable low-temperature preservation. This is important for reducing thermal shock and improving grain storage performance.
