What is a Spiral Freezer? ... Unlike tunnel freezers, which require a long, linear wire-mesh belt to convey products through a sub-zero blast-freezing room, spiral freezers use self-stacking, multi-tiered belts to maintain product quality and minimize the refrigeration space required in the plant.Feb 1, 2020
What is gyro freezer?

What does a blast freezer do?
A blast freezer, also known as a shock freezer, is a type of freezer which is designed to very rapidly bring down the temperature of the contents being stored. They are widely used in commercial kitchens and in the frozen food industry for fresh produce, ice cream, pre-prepared meals and vegetables or fish.
What is a tunnel freezer?
Tunnel Freezers are specialized IQF Freezers that are capable of freezing large quantities of produce in short periods of time while ensuring that the products are frozen without causing any clumps from developing or having the product stick together, thereby compromising quality.
What is spiral belt freezer?
In frozen meal: Freezing. …more compact arrangement employs a spiral belt. The spiral arrangement maximizes the belt surface area for a given floor space. A popular type of spiral freezer uses self-stacking belts. In the self-stacking arrangement, each tier rests on the vertical side flanges of the tier beneath.
How does a spiral freezer work?
Most spiral freezers employ mechanical or cryogenic refrigeration methods, and the use of high-velocity air pumped over the product in either a horizontal (crossflow) or vertical (downflow) arrangement. ... Mechanical freezers use circulating refrigerant to reduce temperatures through a heat exchange with the product.Feb 1, 2020
What is an impingement freezer?
Impingement freezing uses thousands of high-velocity air jets to direct air at the top and bottom surfaces of a product. These jets of air blast away the boundary layer of air that holds heat around the product, resulting in freezing speeds that rival cryogenic.Apr 1, 2013
