What are the primary benefits of a cryogenic tunnel freezer over mechanical freezing?

Cryogenic freezers offer significantly faster freezing rates, which can lead to smaller ice crystals, reduced dehydration, and better product quality. They are also more compact for a given capacity.

What utilities are required for a cryogenic freezer?

The primary utility is the cryogenic gas supply (e.g., liquid nitrogen), typically stored in a bulk tank. Electrical power is also required for fans, controls, and the conveyor belt.

Is this type of freezer suitable for all food products?

Cryogenic freezers are highly versatile but are particularly well-suited for delicate, high-value, or small-particulate products where rapid freezing and quality preservation are critical. Suitability can depend on product moisture content and structure.

What maintenance is typically involved with a cryogenic tunnel freezer?

Routine maintenance commonly includes cleaning the belt and interior, checking fan operation, inspecting conveyor components, and verifying sensor calibration. Regular servicing of the cryogenic supply system is also essential.

Can the freezing time be adjusted?

Yes, units of this type commonly allow for adjustment of the conveyor belt speed and fan settings, which directly impacts the product's residence time and thus the freezing duration.
