Grain Cooler
Product Overview
The grain cooler developed by Zhongrui Technology utilizes the Reverse Carnot Cycle and single-machine vapor compression refrigeration principle. Combined with pseudo-dew-point humidity control and variable-frequency air supply technology, it achieves rapid cooling with high air volume and pressure.
Designed for underground cage cold storage in grain depots, it supports two cooling modes:
- Fresh air cooling: Uses external fresh air for refrigeration.
- Recirculated air cooling: Cycles internal air for refrigeration.
A single unit delivers a maximum cooling capacity of 130kW. Its mobile design enables flexible "one-machine-multiple-uses" applications.
