Why do we need to purchase food packaging machines? With the improvement of living standards, the food industry has higher and higher requirements for packaging. There are also various types of food packaging, and people's demands for packaging quality are also increasing. This is the main reason why we need food packaging machines. So what are the other reasons for buying food packaging machine?
Food packaging machine vacuum-pack food into bags and complete the sealing process after achieving the predetermined vacuum degree. In the food industry, vacuum packaging is very common, with a variety of cured products such as chicken legs, ham, sausage, grilled fish slices, beef jerky, etc., and various pickled foods such as pickles, soy products, fruit preserves, etc. that need to be preserved are increasingly using vacuum packaging. Food that has been vacuum packed has a longer shelf life, greatly extending its quality.
The spoilage of food we see refers to physical changes in appearance and the decay caused mainly by microorganisms, including various enzymatic and non-enzymatic changes in food ingredients and sensory properties, as well as contamination by foreign materials, all of which reduce or completely eliminate the nutritional value of food.
There are many reasons for food spoilage, including microbial growth, oxidation and enzymatic degradation of food ingredients due to oxygen in the air, metabolic processes, and the contamination of harmful substances by insects. Among the many factors that cause food spoilage, microbial contamination is the most common and dominant factor. Generally speaking, bacteria mostly play a role in fish, meat, and vegetable foods, while molds are more prominent in grains and baked goods.
Thus, if we keep food from coming into direct contact with air, keep it in a vacuum state, and prevent the above problems from happening, then we can solve the issue. Our food packaging machine uses this principle: the machine can automatically remove the air inside the packaging bag, achieve the predetermined vacuum degree, and complete the sealing process. Nitrogen or other mixed gases can also be added and then the sealing process can be completed. Food packaging machine is often used in the food industry. Through vacuum packaging, food can be oxidation-resistant, thus achieving the purpose of long-term preservation.
