When using mechanical cooling, air is blown through the container with the help of fans and passes to the back wall of the storage chamber. The air goes down and returns back to the air cooler, and then it is again supplied cooled to the storage.
Drying of the product is minimized due to the large surface of the evaporator and the small temperature difference on the evaporator.
Mechanical cooling can be both in the form of a separate system and intended for installation in warehouses with side storage.
Conditions for effective system operation (//tractor-service.com)
enough space above the containers (1.50 - 1.80 m) for air flow.
smooth walls and ceiling for unhindered air movement
the distance between the rows of containers is the same throughout the warehouse 15 - 20 cm.
it is necessary to provide stable voltage
Advantages of mechanical cooling
fast cooling to the set temperature
long-term storage period
independence from weather conditions
optimal storage of early varieties and varieties that germinate quickly
reduction of losses during storage due to the possibility of a gradual decrease in temperature
