What Is The Principle Of Food Vacuum Packaging Machine And How To Vacuum Seal The Package?

With the improvement of social and economic levels, people's consumption concepts and habits have changed, and the regulations on food have become higher and higher. Vacuum-packed food is very popular with customers. In order to better cope with the development trend of social development, food companies continue to innovate mechanical equipment. In recent years, the Semi Automatic Tray Sealer developed by the manufacturing industry and product research and development departments can not only reduce labor costs, but also increase the production capacity of processing plants. So, what kind of mechanical equipment is a food vacuum packaging machine?

Food vacuum packaging machine is one of the small vacuum packaging machines that can be used for vacuum packaging. Vacuum packaging refers to the automatic sealing of the packaging bag immediately after the vacuum machine draws it into a low vacuum. Due to the high vacuum in the bag and less residual air, the reproduction of microorganisms such as bacteria is controlled, and the oxidation of the items is avoided. Mildew and corruption, at the same time, for some soft items, after vacuum packaging, the packaging volume can be reduced, which is convenient for transportation and storage. The vacuum machine uses plastic composite film and plastic aluminum foil composite film as packaging materials to vacuum pack solid, liquid, powdered, paste food, grain, fruit, soy sauce, preserved fruit, chemicals, electronic components, precision instruments, rare metals, etc. After packaging, it can effectively prevent the product (commodity) from oxidation, mildew, corruption, and moisture, so as to maintain quality, freshness, flavor, and color, and extend the shelf life of the product. The machine cover is made of transparent plexiglass, and the packaging process is clear at a glance. The food vacuum packaging machine has the functions of vacuuming, sealing, and completing in one go. It meets different packaging materials and different packaging requirements.

The food vacuum packaging machine can make the packaging bag in a vacuum state, achieving a sterile effect. If the customer can choose the right packaging material, the vacuum packaging of the food can achieve the expected freshness. The process is mainly to evacuate and then seal.

Deoxygenation of meat products can control the growth and development of mold and aerobic bacteria, control the oxidation of oil components, control the deterioration of food, and achieve the purpose of preservation. As for fruit thinning, reduce the oxygen content in the bag, and the fruit produces carbon dioxide through anaerobic respiration, while maintaining a certain humidity. This low-oxygen, high-carbon dioxide, and high-humidity environment can effectively reduce fruit transpiration, reduce fruit respiration, reduce ethylene production and nutrient consumption, and achieve the purpose of preservation. In addition, for other foods, it can reduce the evaporation of water and control the condensation and solidification caused by food dehydration.

In addition to the above functions, it also has the advantages of resisting mechanical pressure, reducing vibration, and facilitating long-distance transportation. The original color, aroma, taste, shape and nutritional value of food can be more effectively maintained.
