What is Grain Cooling unit?

HICON grain cooling and grain storage cooling unit includes two series:grain cooling unit (grain chiler unit) and grain storage coling unit (granary cooling unit).The unit indudes two series: grain chiller unit and granary cooling unit. The granary cooling unit indudes split, integral, controlled atmosphere cdlosed, and processed grain models. A variety of refrigerants, air suply distances and other parameters are available to meet the needs of different occasions and environments.

About it Operating Principle

The ambient air passes through the filter to remove dust and impurities, and then enters the evaporator for cooling. The air temperature decreases and the humidity increases to become high-humidity cold air. The cold and humid air is heated, dried and conditioned by the post-heating system, and then the air whose temperature and humidity meet the requirements of the set value is sent into the granary through the centrifugal fan (variable frequency speed regulation). The air supply temperature and humidity are automatically controlled and regulated by PLC system.

PLC control is adopted to automaticlly control and regulate the air supply temperature and humidity. The variable frequency centrifugal fan is used to automatically control the air supply volume and static pressure, and the back-end condensate recovery is adopted for reheating,so that the temperature and humidity control is more precise and energy-saving. The heat exchanger is calculated and matched to improve the coling and dehumidification effect of the unit.

About the Range of Application

This equipment is suitable for low-temperature ventilation of various types of grains and oil seeds indiferent granary types such as vertical silo,squat silo and horizontal bin, Grain wholehouse, Food storage room and so on. The grain ciller is suitable for horizontal grain cooling and ventilation of horizontal bins such as rice, wheat and corn.

Product Advantages

Maintain the grain storage quality, delay grain aging, and achieve preservation and storage of grains

By precisely controlling the temperature and humidity environment in the granary, the respiration of grain and the decomposition of nutrients can be effectively delayed, the activity of lipase can be significantly inhibited, and the increase of fatty acid values can be prevented, thereby maintaining the original freshness, taste and nutritional value of the grain and achieving long-term fresh storage.

Inhibit pests and diseases, avoid chemical fumigation pollution, and achieve green grain storage

By creating a low-temperature, dry storage environment, we fundamentally inhibit the hatching of insect eggs and the growth of mold, achieving physical control. This can significantly reduce or even eliminate the use of chemical agents, avoid drug residues and environmental pollution, ensure food safety and ecological protection, and align with the development direction of green grain storage.

Store grains safely and reduce losses

This effectively addresses issues related to mildew caused by condensation and localized heating in grain piles, eliminating potential safety hazards associated with grain storage. By maintaining a stable grain pile, losses due to quality deterioration and pest and rodent infestation are significantly reduced, ensuring the safety of stored grain and its stable value.

High efficiency design and low operating cost

Utilizing a highly efficient refrigeration system and intelligent control strategies, the system consumes far less energy than traditional refrigeration equipment. The system automatically selects the optimal operating mode based on the external environment, fully utilizing natural cooling resources such as nighttime low temperatures, significantly reducing cooling costs per ton of grain and achieving outstanding economic efficiency.

Reliable operation and easy operation

The fully automatic intelligent control system features one-touch start/stop and fault self-diagnosis, simplifying operation and reducing reliance on manpower. Core components are selected from high-quality brands and rigorously tested and verified to ensure long-term stability, reliability, and a long service life.

With the continuous improvement of people's awareness of grain quality and living standards, their requirements for grain quality and pollution-fre grains il gradually increase. It is an inevitable trend in development to phase out the traditional normal temperature storage, drug fumigation and insecticide methods in the process of grain storage.
