Product Description

Customized liquid nitrogen tunnel freezer for fast food preservation

Product Introduction
The liquid nitrogen tunnel freezer is an efficient ultra-low temperature freezing equipment designed specifically for continuous production in the food industry. It utilizes the instantaneous heat absorption property of liquid nitrogen at -196 ℃, and achieves rapid freezing of food ingredients (cooling rate ≥ 30 ℃/min) and cell level freshness locking through a closed tunnel structure and intelligent temperature control system. Suitable for large-scale processing of high value-added products such as seafood, meat, and pre made dishes, significantly improving quality and reducing loss rates, it is a modern freezing solution that replaces traditional cold storage.

PRODUCT FUNCTION
Fast freezing locks freshness
Ultra low temperature freezing: The working temperature can be adjusted from -190 ℃ to -120 ℃, and it can penetrate the center of the ingredient within 5-15 minutes (taking 25mm thick steak as an example). The ice grain size is ≤ 5 μ m to avoid cell rupture, and the juice loss rate after thawing is less than 3%.
Uniform temperature control: multi-stage axial flow fan+optimized design of air duct, circulating at a wind speed of 10m/s, temperature fluctuation in the tunnel ≤ ± 5 ℃.
Continuous intelligent production
Flexible transmission system: 304 stainless steel mesh belt infinite speed regulation (5-25mm/s), supporting seamless connection with pre-treatment and packaging lines, and 24-hour continuous operation.
Automation control: PLC+touch screen real-time monitoring of liquid nitrogen injection volume, temperature curve, and mesh belt speed, with fault self diagnosis and data traceability functions.
Value added service support
Modular Expansion: Supports customization of tunnel length, mesh belt size, and more.
