The use of sausage vacuum packaging machine
The sausage has a unique flavor and is easy to eat. It can be eaten after opening the package or simply heating it. It is a very convenient and delicious food. Sausages are generally made of minced fresh meat and stuffed into casings. The sausage itself is a method of meat preservation, and the sales of sausages are not subject to geographical restrictions and can be distributed to many places, which is very different from the packaging of sausages. Relationship. Sausage packaging is generally used as a sausage vacuum packaging machine.
Why use vacuum packaging？
Different foods have different flavors and nutritional values, but their shelf life and properties are different, so there will be certain differences in storage methods and packaging. Meat food, in particular, is easy to deteriorate. Only qualified packaging using vacuum technology can ensure long shelf life.
Vacuum packaging can also avoid food oxidation because oily foods contain a lot of unsaturated fatty acids, which are prone to oxidation after contact with oxygen, which makes the food taste bad and degenerate. In addition, oxidation also leads to the loss of vitamin A and vitamin C, and the unstable substances in food coloring are affected by the effect of oxygen, darkening the color. Therefore, deoxygenation can effectively prevent food from deteriorating and maintain its color, aroma, taste, and nutritional value.
Do I still need to refrigerate after vacuum packaging?
| temperature | non-vacuum | vacuum |
| Refrigerated preservation (5±3℃) | 2-3 days | 12-13 days |
| Cryopreservation (-16±20℃) | 2-3 months | one year |
As can be seen from the above table, the temperature has a great influence on the shelf life of meat, and the frozen storage time is longer than the chilled fresh, and the vacuum storage time is longer than the non-vacuum storage time. Refrigerated storage can be extended to one year after vacuum packaging. So it still needs to be preserved after vacuum packaging.
Advantages of vacuum packaging sausages
Vacuum packaging can prolong the shelf life of food, has the effects of resistance to pressure, gas resistance, preservation, etc., and can more effectively maintain the original color, aroma, taste, shape, and nutritional value of food for a long time. It has great advantages in storage and transportation. It has the advantages of small volume after vacuum extraction, reduced storage and transportation costs, and shock resistance.
How to choose sausage vacuum packaging bags？
There are basically two types of vacuum packaging bags for sausages, one is a transparent plastic packaging bag, and the other is an aluminum foil packaging bag. In the subdivision, it is divided into vacuum packaging bags that can be used in different environments, which are divided into sterilized food vacuum bags, retort sterilized food vacuum bags, high temperature sterilized food vacuum bags and frozen and refrigerated food vacuum bags. Among them, the highest temperature-resistant food vacuum bag is the high-temperature sterilization food vacuum bag, which can withstand high temperatures above 121 °C. Therefore, when choosing a vacuum packaging bag, in addition to choosing whether it is transparent, it is more important to look at the applicable temperature of the packaging bag.
Precautions for using sausage vacuum packaging machine
1. The packaging machine should work in an environment where the temperature is -10℃～60℃, the relative humidity is not more than 85%; there is no corrosive gas in the surrounding air, no powder, and no explosive dangerous goods.
2. The oil level of the vacuum pump should be checked regularly, and the oil level should be added regularly to keep the oil level at the position of 1/2 to 3/4 of the oil window; the vacuum pump adopts imported No. 30 automobile oil or special oil for vacuum No. 0 pump.
3. However, if it is observed that the oil in the pump turns black, there are water droplets in the oil or the viscosity increases, it proves that the oil has been contaminated, and the oil should be replaced immediately. Under normal circumstances, replace the pump measurement every 1-2 months of continuous operation.
4. The model with a water removal device should regularly drain water from the drainpipe at the rear of the equipment according to the moisture content of the package, and then put the pipe plug after draining the water. Generally, the water will be automatically decomposed and no discharge is required.
