Overview

The LONKIA liquid nitrogen chicken quick freezer features a tunnel-type continuous conveyor design that uses liquid nitrogen as the refrigerant and achieves rapid cooling through multiple sets of spray evaporation units and circulation fans. Chicken is continuously fed into the quick-freezing tunnel via a food-grade stainless steel conveyor belt, where it is frozen in a preset low-temperature environment before being transported from the discharge end to subsequent packaging or cold storage processes.

The fast freezing equipment utilizes a PLC-based intelligent control system that allows for adjustment of conveyor speed, freezing time, and temperatures in different zones, meeting the demands of continuous chicken processing. The quick freezer design prioritizes the hygiene of food-contact components, operational stability at low temperatures, and production efficiency.

Advantage

  • Rapid Cooling with Liquid Nitrogen-Utilizes the heat absorption from the low-temperature vaporization of liquid nitrogen to achieve rapid cooling and shorten food freezing time, making it suitable for chicken processing operations that require high quick freezing efficiency.
  • Multi-Point Spray and Independent Temperature Control-Equipped with multiple sets of liquid nitrogen atomizing spray devices and pneumatic flow control valves, the chicken liquid nitrogen quick freezer enables independent temperature control in different freezing zones, promoting uniform freezing of the chicken.
  • Food-Grade SUS304 Stainless Steel Construction-The conveyor belt, internal frame of the quick-freezing zone, supports, air deflectors, and all components in direct contact with food are made of food-grade SUS304 stainless steel, meeting the hygiene design requirements for food processing equipment.
  • Wide Range of Applications-The quick freezer is not only suitable for the rapid freezing of chicken but can also be used for the quick-freezing of various foods such as beef, pork, fish, seafood, fruits, and vegetables, meeting the freezing needs of different food processing industries.
  • High Product Quality-The industrial meat freezer utilizes liquid nitrogen for rapid freezing at low temperatures, shortening the time food spends in the zone where ice crystals form most intensively. This helps minimize the impact of ice crystals on the food’s tissue structure, reduces juice loss during thawing, and better preserves the product’s original shape, texture, and freshness.

Individual Quick Freezing Process

The individual quick freezing process is simple and efficient. 

Firstly, the chicken enters the quick freezing tunnel via a food-grade SUS304 stainless steel conveyor belt. Liquid nitrogen is atomized by multiple sets of spray evaporation devices and rapidly vaporizes, quickly removing heat from the chicken through the low-temperature heat absorption effect.

At the same time, the quick freezer uses a recirculating fan to circulate low-temperature nitrogen gas and, combined with multi-point spraying and multi-stage independent temperature control technology, ensures uniform distribution of cold air within the tunnel.

Heat exchange occurs continuously as the chicken moves along the conveyor. By adjusting the conveyor speed, freezing time, and liquid nitrogen spray volume, the system achieves continuous, rapid, and uniform freezing.
