What Does Air-Blast Freezers Means?

Post Time: 23 July 2018

Most air-blast freezers are of continuous operation; the product is carried on a conveyor that moves through a stream of high-velocity air. The length and speed of the conveyor establish the residence of freezing time. These times can be relatively small based on the use of very low-temperature air, high air velocities, and good contact between individual product packages and the cold air.
Continuous air-blast freezing systems use a variety of different conveying arrangements for movement of product through the refrigerated air. Alternate arrangements include tray conveyors, spiral conveyors, and roller conveyors.
