The tunnel-type liquid nitrogen quick-freezing machine adopts a fully welded, stainless steel body, which meets the new version of European EHEDG and American USDA standards. Tunnel-type liquid nitrogen quick-freezing machine is suitable for any food that needs to be cooled, quick-frozen or crusted/hardened and frozen in assembly line or continuous production. Tunnel-type quick-freezing machine can also guarantee the quality of food.
Tunnel liquid nitrogen quick freezing machine is mainly used for quick freezing of food. The control method of touch screen + PLC is adopted to monitor the temperature change in the box in real time. After the parameters are set, the equipment can run automatically. The operation is simple, the reliability is strong, and the operation ends with automatic alarm.
The tunnel-type liquid nitrogen quick-freezing machine uses liquid nitrogen as the cooling medium to freeze food quickly and powerfully. Because the quick-freezing is relatively fast, it will not damage the internal tissue structure of the food, thus ensuring the authenticity, original juice, original color and nutrition of the food It has excellent chemical properties, and the drying consumption is very small, and it can realize rapid freezing of monomers without adhesion loss.
Advantages of tunnel liquid nitrogen quick freezer:
① Freeze in 5 minutes, the cooling rate is ≥50℃/min, the freezing speed is fast (the freezing speed is about 30-40 times faster than the general freezing method), and the quick freezing with liquid nitrogen can make the food quickly pass through the large ice crystal growth zone of 0℃～5℃.
②Maintaining food quality: due to the short freezing time of liquid nitrogen and the low temperature of -196°C, the food frozen with liquid nitrogen can maintain the color, aroma, taste and nutritional value before processing to the greatest extent. The taste of the food is better than that of the traditional quick-freezing method.
③ Small dry consumption of materials: Generally, the dry consumption loss rate of freezing is 3-6%, while quick freezing with liquid nitrogen can reduce it to 0.25-0.5%.
The cost of equipment and power is low, the one-time investment of equipment is small, the operating cost is low, it is easy to realize mechanization and automatic assembly line, and improve productivity.
④The operation is simple, and unmanned operation is possible; the maintenance cost is low, and there is almost no maintenance cost.
⑤The floor area is very small and there is no noise.
The advantages of the tunnel-type liquid nitrogen quick-freezing machine are: small footprint, flexible adjustment of output, simple operation, convenient cleaning and maintenance, no pollution and noise, economical and environmentally friendly. The freezing time is short, the effect is good, and the best freezing effect is achieved with the least energy consumption. It is widely used in various quick-frozen foods such as meat, seafood and aquatic products, shabu-shabu, fruits, vegetables, and pasta. Such as: seafood, abalone, sea shrimp, sea cucumber, lobster, sea fish, salmon, crab, meat, glutinous rice balls, dumplings, buns, rice dumplings, spring rolls, wontons, cheese products, bamboo shoots, sticky corn, velvet antler, strawberries, pineapple, red bayberry, papaya , litchi, prepared food, etc.
