Introduction to liquid nitrogen air-cooled tunnel freezer:

Equipment material: 2mm SUS304 stainless steel inside and outside, overall stainless steel square tube frame

Distribution specification: 380V/50HZ

Working temperature: -20~-120 ℃

Temperature control accuracy: ± 1 ℃

Cooling rate: 1-50 ℃/min

Equipment insulation: 160mm thick, double-layer insulation, excellent insulation performance.

Food conveying: SUS304 food specific conveyor belt, speed and elasticity can be automatically adjusted.

Liquid nitrogen control: German imported solenoid valve and manual shut-off valve combined control to ensure sufficient safety.

Air cooling cycle: high-power fan with reinforced axial fan, fast and uniform cooling speed, dual air locking function at both ends, effectively reducing cold air leakage.

Electrical control: human-machine interface+PLC+module programmable control, easy to learn input, intuitive and reliable control, with temperature monitoring and alarm functions, electrical lock, ensuring safe operation of equipment and processes

Equipment maintenance: The bottom of the body is equipped with a drainage outlet, with a long-life and low consumable design, easy replacement of vulnerable parts, and good maintainability.

This equipment is suitable for industrial production modes with large quantities, continuity, few personnel, and large areas. It can be combined with other food production lines to form an automatic line.
