Functional characteristics of the box freezer

The box freezer has a built-in plurality of stainless steel material trays, which spray droplets directly to the surface of the material through the nozzle, and the materials are excitedly exchanged with low-temperature nitrogen through the fan on the stainless steel disc for heat exchange for rapid freezing
.
The vaporized low-temperature nitrogen is discharged from the exhaust port, and 1kg of food is quickly frozen, and the liquid nitrogen consumption is about 0.
5-1.
5kg
.
Due to the short freezing time and the direct vaporization and heat exchange mainly by liquid nitrogen, the drying consumption of frozen products is much
smaller than that of the air-cooled method.
Functional characteristics of box-type quick freezer: 1.
Material support: mobile adjustable 304 stainless steel material rack; 2.
Refrigeration system: liquid nitrogen vaporization evaporative refrigeration system, pneumatic solenoid valve temperature drop, frequency conversion speed regulation double fan circulating refrigeration; 3.
Equipment insulation: the insulation layer is aerogel insulation blanket plus polyurethane foam insulation, thickness 150mm, excellent and safe thermal insulation performance; 4.
Equipment system: liquid nitrogen circulating atomization spray system with imported technology from Germany; 5.
Air-cooled circulation: high-power fan is equipped with reinforced axial fan, the air speed is adjustable, and the cooling speed is fast and uniform; 6.
Equipment control: touch screen + PLC automatic program control system, easy to learn, intuitive and reliable control, with temperature monitoring and alarm functions to ensure the safety of equipment and process operation; 7.
Equipment maintenance: easy to clean, easy to maintain, long life and low consumables design
