　　The seafood quick-freezing equipment has been updated yet? Look at the liquid nitrogen quick-freezer, save money time!

Speaking of frozen seafood, everyone’s first impression must be equated with cheap goods poor quality. Many people would rather eat live chilled seafood. Even if they buy farmed seafood, they don’t want to buy frozen aquatic products. The bigger, the more ingrained the concept. This is related to the backwardness of my country's aquatic products preservation cold storage technology since the last century. The original fishing fleet mostly carried out individual fishing operations, the overall operation was in a state of extensive operation. In addition, due to capital technology, the fishing boats generally lacked modern refrigeration preservation equipment. Therefore, after the aquatic products are caught, there is no way to do it. Disposal is stopped for a while, the catch can only be brought back to shore at room temperature then refrigerated. At this time, there is often a period of time when the seafood is harvested delivered at intervals. The fish stops freezing when they are dead, the freezing temperature is enough. -17 degrees, so the quality will inevitably be affected.

The biggest difference is the difference between live freezing dead freezing. Whether the frozen products are frozen at -17 degrees when the fish is still alive, before the hard period is just caught, it can only be frozen at -17 degrees compared to the past. Today's -35 quick-freezing equipment is more advanced in technology. The quick-freezing process has been completed before the fish shrimps begin to oxidize metamorphose, the core temperature of the fish has dropped to more than -17 degrees within 8 hours.

However, the tunnel-type compactor quick-freezing machine is a more commonly used traditional one. The general theoretical temperature can reach minus 35 degrees, the freezing time is generally about half an hour. The machine itself is relatively expensive. The later operating cost is mainly the electricity cost of the compactor, subsequent maintenance It is relatively troublesome has no preservation effect.

Tunnel-type liquid nitrogen quick-freezing machine is a relatively new quick-freezing method that has emerged in China in recent years. It has been used more abroad before. This technology has gradually matured developed in China in recent years. Because of the The request is getting higher higher, there will be more more companies using liquid nitrogen quick-freezing machines in the later period. The cost of the machine itself is much lower than that of the compacting machine. The later operating costs are mainly the cost of liquid nitrogen. Because the liquid nitrogen quick-freezing machine freezes food time to time If liquid nitrogen is consumed, the theoretical consumption is that it takes 10-15 minutes to freeze a ton of food, it consumes about 1.2 tons of liquid nitrogen.

　　The overall cost is calculated, the advantage of liquid nitrogen quick freezing is higher, the quick freezing time is short the efficiency is high. Economical environmentally friendly, to ensure the high quality of food is an important condition for selecting equipment.

　　 Liquid nitrogen is an internationally recognized non-toxic, non-corrosive inert to food ingredients. It is by far the most environmentally friendly economical freezing cooling medium in the world. Liquid nitrogen quick-freezing equipment uses -196°C as the refrigerant, so it can achieve extreme freezing. The food that has been quick-frozen by liquid nitrogen can maintain the color, aroma, taste nutritional value before processing to the maximum. Reduce water loss, no loss, no weight reduction, the ice storage tube coil adheres to the original novelty improves the quality of production.

Compared with ordinary mechanical cooling equipment, 　　 liquid nitrogen quick freezing machine has a dry loss rate of 3 to 6%, while liquid nitrogen quick freezing can be reduced to 0.25 to 0.5%. The installation of liquid nitrogen relies on liquid nitrogen phase change refrigeration the transformation of internal energy to achieve the purpose of quick freezing preservation. Unlike ordinary refrigeration systems, which require a large amount of electrical energy to drive the refrigeration machinery when freezing, so the principle of refrigeration, it It does directly consume electrical energy. Moreover, the maintenance cost is low, it is hygienic clean, it can be easily connected to the existing consumption line.

The 　　 liquid nitrogen speed machine can reach a maximum freezing speed of 5 minutes, which means that enterprises do need to store a large amount of products, can greatly shorten the time to market for products, can completely deal with problems such as oversupply, obsolescence, transformation. the shelf life is longer, which is 1 to 3 times the shelf life of traditional quick-freezing. According to market demand, we will constantly improve improve the automation, intelligence, energy-saving aspects of the equipment, so that the product can achieve the best freezing effect with the minimum energy consumption.
