The Smart Differential Pressure Pre-Cooling System is a precision-controlled pre-cooling solution designed to minimize freshness loss and extend the quality retention period of agricultural products immediately after harvest. Unlike conventional cooling methods, this system artificially creates a differential pressure within the storage space to block external air inflow, featuring a high-seal structure that enables internal cold air to circulate exclusively.

During the pre-cooling process, chilled air is supplied through a blower module to rapidly remove residual heat from the surface of the crops. At the same time, internal air is continuously discharged through intake ducts to maintain a negative pressure environment. This enhances the concentration and circulation efficiency of the cold air, effectively preserving freshness, moisture content, and tissue elasticity of the produce.

In addition, the system integrates comprehensive environmental management functions including temperature and humidity control, fumigation, and sterilization. These features meet the hygiene standards required to maintain product quality during subsequent distribution stages.

The system can be manufactured in both fixed and mobile formats and customized for various agricultural and logistics environments such as greenhouses, agricultural storage facilities, and cold-chain logistics centers.

With smart control-based automated operation technology, the system can be run without specialized personnel. Its performance has been validated through storage tests with actual crops—such as eco-certified flower-shaped lion’s mane mushrooms. Particularly effective for improving storage efficiency and ensuring predictable quality retention of high-value crops that are sensitive to weather conditions, this system serves as a core piece of equipment for smart agriculture and export-focused produce management.
