Chengdu Zhuoda Yuntong Liquid Nitrogen Freezing Machine

What is liquid nitrogen?

Liquid nitrogen, liquid nitrogen gas. It is inert, colorless, odorless, non corrosive, non flammable, and has an extremely low temperature. Nitrogen constitutes the majority of the atmosphere (78.03% by volume and 75.5% by weight). Nitrogen is inert and does not support combustion. A large amount of heat absorption during vaporization is caused by contact. Nitrogen accounts for 78% of the air, and the temperature of liquid nitrogen reaches -196 ℃. It is a relatively environmentally friendly new energy source for refrigeration today, and can be widely used in food freezing, medical freezing, aviation, animal husbandry, and other industries.

Introduction and characteristics of tunnel type liquid nitrogen quick freezing machine
1. Adopting a simple and easy to clean design concept, there is no need to shut down for defrosting, and continuous production can improve production efficiency;
2. The working temperature of the liquid nitrogen freezer can be set arbitrarily between -30 ° C and -120 ° C, and it can freeze various seafood, meat, fish and whole fish, fruits and vegetables, buns, instant fast food, baked goods, and more.
3. The control system consists of Siemens PLC programmable control host, Schneider electrical components, touch screen operation, real-time alarm device, frequency converter, etc;
4. The operating system adopts a touch screen control panel, which is a one click start mode and easy to learn. All operating data is clear at a glance, and the operating speed and freezing temperature can be adjusted at any time. The temperature changes inside the freezing tunnel are monitored in real time;
5. The cooling circulation and exhaust system inside the tunnel consists of a dedicated motor and a low-temperature fan (patented technology). The low-temperature fan inside the tunnel does not need to be stopped for defrosting and can operate continuously without being frozen, while ensuring that food is quickly and evenly frozen and the refrigerant is utilized to the maximum efficiency;
6. The amount of liquid nitrogen required for quick freezing is automatically adjusted according to the set temperature, and the opening degree of the valve is automatically adjusted to maximize the saving of liquid nitrogen usage while ensuring uniform temperature inside the tunnel;
7. The upper cover of the freezer tunnel can be vertically raised and lowered, and the lower inner groove adopts an inclined collection and drainage structure, which can fully clean the inside of the tunnel and ensure the hygiene and safety of frozen food;
8. The quick freezing machine adopts a segmented design, which makes on-site lifting and assembly quick and convenient.
Overall design:
1. Design process structure parameters based on the characteristics of frozen products, and use a multi-point liquid nitrogen atomization evaporator to ensure uniform temperature in the freezing chamber, fully meeting the requirements;
2. The optimized combination of evaporator fan, air guide device, adjustable heat fluctuation device, and bottom plate upward movement structure improves the cold air force point and quick freezing rate of frozen products, allowing the frozen products to be evenly winded in multiple directions, making the freezing of frozen products faster and the quality more uniform;
3. The air guide adjustment device can adjust the wind direction at any time to control the symmetry of the cold air and prevent it from overflowing; Adjustable windbreak insulation device controls the feeding height and avoids loss of cooling capacity; The five sided insulation device of the incoming and outgoing cargo rack further utilizes cold air to enable the conveyor belt to operate at low temperatures, improve the low-temperature environment of incoming and outgoing materials, and enhance efficiency;
4. The warehouse body adopts ultra thick polyurethane insulation board; Ultra thick 304 stainless steel anti-collision outer plate; The maintenance door is equipped with double twisted chain double door plugs, which are resistant to low temperature, aging, and oil, and sealed with double rubber strips;
5. The framework structure, brackets, supports, platforms, air duct panels, mesh belts, guide rail frames, and machine components in the frozen area are all made of food grade SUS304 stainless steel (except for standard and special parts such as reducers and motors);
6. Full length stainless steel edge to prevent frozen products from overflowing; Ultra high molecular weight polyethylene slide rail.
7. Install a welded stainless steel large water tray in the quick freezing room; The bottom plate is inclined to avoid ice and water accumulation; The corners of the quick freezing machine are easy to clean and maintain; Except for the slow operation of the mesh belt, all other transmission devices are located inside the cover, which is easy to disassemble and assemble; Set up emergency stop safety buttons and safety warning signs; The bottom plate of the quick freezing machine can be adjusted with adjustable legs. The overall structure complies with HACCP safety and hygiene requirements, with safe and reliable operation and food safety and hygiene;
Seafood tunnel type liquid nitrogen freezer SD
1. Because the freezing time of the liquid nitrogen speed machine is extremely short, it avoids the formation of large ice crystals between cells.
2. Liquid nitrogen quick freezing, due to its rapid freezing, can reduce the water leakage inside food cells, and the loss of juice during thawing is also very small, resulting in a longer preservation time for food.
3. The time for concentrated solutes inside food cell tissues to come into contact with food tissues, colloids, and various components is greatly reduced, and the harm caused is also minimized.
4. Due to the rapid freezing of liquid nitrogen, microorganisms are rapidly reduced to a temperature below their growth activity, which effectively inhibits or kills their growth and biochemical reactions.
5. The seafood liquid nitrogen mini freezer freezes quickly, taking only a few minutes to a dozen minutes, with high freezing efficiency and low operating costs.
6. Due to the use of ultra-low temperature freezing technology in the liquid nitrogen seafood mini freezer, it completes the disinfection and sterilization process during the seafood freezing process. The frozen products can be directly stored in a -25 ℃ freezer without worrying about bacterial growth and damage to the food itself.
7. The residence time of food in liquid nitrogen freezing process is relatively short, which is conducive to improving equipment utilization and continuous production. Food begins to freeze when it drops to -1 ℃, and most of the ice crystals are formed between -1 ℃ and -5 ℃, which is the stage of ice crystal formation. The liquid nitrogen freezer greatly shortens the freezing time of this freezing stage, which eliminates this part of heat as quickly as possible and can effectively improve the quality of food.
8. The equipment is easy to operate, greatly reducing manual labor and lowering the skill requirements for operators. It also occupies very little factory space, is easy to clean, and has low maintenance costs.
9. The installation cost is very small, the maintenance cost is low, and each device can independently adjust the freezing temperature, time, and transmission speed.
