Application of liquid nitrogen dosing machine in beverage industry
The beverages on the market are mainly sold in two-piece cans, three-piece cans, PET bottles and cartons. Most of the two-piece cans are aluminum, thin and light, which can effectively reduce transportation costs. The disadvantage is easy to cause cans of deflated, especially when filling non-carbonated drinks. Three-piece cans are mostly made of iron and are mainly used for filling non-carbonated beverages. They are sturdy and not prone to collapse, but three-piece cans are relatively heavy. In recent years, the price of iron has been rising, which makes manufacturing more expensive.
When there are bugs in an application, there are always people trying to fix them. For example, how to reduce the cost of three cans, how to reduce the collapse of two cans. Thus, a method was developed - liquid nitrogen dosing technology.
We have good liquid nitrogen dosing machine and high quality liquid nitrogen dosing machine.
If you want to reduce the cost of cans, you can make two cans instead of three. Because aluminum cans are lighter than iron cans, the average aluminum can is 13 grams, compared with 45 grams for the same volume of iron cans. If you want to reduce the production of the discharge tank, you can use liquid nitrogen drip. Because liquid nitrogen drops in the tank to produce internal pressure, the product can enter the sterilization pot, at 121 ℃ for long-term sterilization, so that the tank will not collapse after cooling, in the packaging and handling process will not deformation process.
The specific operation is: after filling and before entering the sealing, the modern liquid nitrogen injection technology is used to accurately inject liquid nitrogen at -196 ℃ and then seal immediately. The liquid nitrogen absorbs heat in a short time and expands 700 times to become nitrogen. This has two advantages. Drive away the air (especially oxygen) in the tank, so that the shelf life of the product is longer; Aluminum cans do not rust and are good for refrigeration.
