    Liquid nitrogen quick-freezing equipment is suitable for the production of high value-added foods, such as: processing fish and shrimp, shrimp, seafood, fresh river, fresh meat, meat products, fine fruits, off-season fruits, medicinal materials, etc. Man-machine interface + PLC + module programmable control, input is simple and easy to learn, control is intuitive and reliable, with temperature monitoring and alarm functions, electrical interlocking, to ensure the safety of equipment and process operation. Long-life and low-consumable design, easy and quick replacement of wearing parts, and excellent maintainability. It can be a large-scale, continuous, small-person and large-scale industrial production model, and can be combined with other food lines to become an automatic line.

    Equipment material: The inside and outside of the equipment cavity are made of SUS304 stainless steel, which is durable and does not rust.

    Working temperature: -196℃——+120℃

    Temperature control accuracy: ±2℃

    Temperature uniformity: ±5℃

    Cooling speed: ≥20℃/min

    Heating speed: ≥5℃/min

    Power distribution specifications: 380V50HZ 220V50HZ

    Liquid nitrogen pressure: 5-10bar

    Temperature sensor: A grade PT100 platinum resistance.

    Equipment insulation: 150mm thick, double-layer insulation, excellent insulation performance.

    Liquid nitrogen control valve: the imported solenoid valve and the manual liquid nitrogen shut-off valve are jointly controlled to ensure sufficient safety.

    Air-cooled circulation: The high-power fan is equipped with an enhanced axial fan, and the wind speed can reach 10m/s, which is fast and uniform.
