Congelation refrigerating room
in order to reduce the dry food consumption, between congelation refrigeration cooling device used more cooling tube, but now there are using air cooler as storage refrigeration cooling device with packaged foods.
Lyophilizer sent along the air refrigerating room flat DingTie take the jet to the wall, then ejector a big reflow area, food a backflow region, wind speed at 0.
5 m/S, so as to reduce food consumption.
cooling refrigeration storage are fruits and vegetables, fresh eggs, such as fresh food, required to maintain constant temperature and humidity, the rolls the regional temperature difference should be less than 0.
5 ℃, humidity difference is less than 4%, because food has not been stopped breathing, heat exchange is bigger, so the required air flow uniform distribution, so the uniform air duct.
When the cold room
width is more than 12 m, supply air duct is located in the cold room above the middle aisle;
Width is less than 12 m, blast pipe in cold room above.
