Rapid Crust Freezing for Productivity Improvement

CRYOLINE^® RC Rapid Crust Freezer

Specialty Freezer for Sliced & Diced Products

The CRYOLINE RC freezer is best suited for crust freezing pre-cut deli meat such as ham, sausage, and cooked meat, or portioned whole cuts such as pre-cut steaks. Proper crust freezing helps to preserve product quality by reducing the risk of tears and crumbling while also increasing portioning accuracy due to the firmer product structure.

Liquid Nitrogen Rapidly Freezes the Surface

The CRYOLINE® RC rapid crust freezer is a specialized semi-batch unit built for freezing the surface of larger pieces of food products prior to portioning using methods such as slicing or dicing. The rapid crust freezer is a specialized semi-batch unit built for freezing the surface of larger pieces of food products prior to portioning using methods such as slicing or dicing. The CRYOLINE RC technology uses high-velocity nitrogen gas to rapidly freeze the product surface.

An Optimal Rate of Heat Transfer with Liquid Nitrogen

High-velocity nitrogen gas flow is parallel to the product’s transfer pathway and results in a high rate of heat transfer while providing uniform crust freezing across the surface of the products. In addition, liquid nitrogen is also directly sprayed into the gas stream to maximize the rate of heat transfer. The nitrogen continues to circulate for a given dwell time before exiting the system through an exhaust vent. More information about the rapid crust freezer

This fast heat transfer produces a freezer with a small footprint, a short dwell time, and highly efficient crust freezing. Within the freezer, the gas flow is generated with a centrifugal fan and funneled through tight spaces between products. This funneling creates high-velocity gas, which effectively takes heat away from food. In addition, liquid nitrogen is also directly sprayed into the gas stream to maximize the rate of heat transfer. The nitrogen continues to circulate for a given dwell time before exiting the system through an exhaust vent.

For optimum hygiene and sanitation, all internal components are made of stainless steel or polyethylene and designed with sloped surfaces, rounded corners, proper drainage, and polished welds. Additionally, the CRYOLINE RC features an electrically driven top-lifting design which ensures full access and separation of mechanical components for cleaning internal surface
