Liquid Quick Deep Freezer:

This s a revolutionary method of quick freezing, instead of air blast freezer, our liquid quick freezer can freeze product quickly with food grade super-conductive liquid, it is suitable for freezeing many kinds of product such as vegetables ,whole fish, crab, especially for lobster and tuna loin fish.

Conventional air blast freezer always blow cold air on the surface of the products, because of the high heat-resistance of air, heat exchange is very slow, resulting in very long freezing time. More importantly, it will take too much time to go trough the ice crystal formation zone(0 to -5°C) that produces a large ice crystal inside the cells, tearing the membrane of cells, causing the loss the nutrition, protein and electrolytes during defrosting.

With the special food grade natural super-conductive liquid, we will get more efficiency of heat exchange, shorter freezing time, about 1/10 times comparing with conventional air cooled blast freezer. It will make great homogeneous temperature of product due to its less freezing time. The substance in the cell is almost unchanged, so the flavor and texture is as same as fresh after defrosting.

Features:

• submerge product in to the frozen solution which can contact with product every corner
• Food grade special freezing liquid
• Deep freezing temperature:lower than -40°C .
• 1/15 freezing time as conventional freezer,quick freezing
• product can be kept longer because of its deep frozen temperature and short freezing time
• quick frozen means minimum capital cost and enegy cost
• better frozen effect. fresh row orginal condition when thawing. no loss of protein and nutrition.
