In modern society, food safety and preservation are one of the most concerned issues for consumers. In order to meet people's demand for high-quality food, fully automatic vacuum food packaging machines came into being. This innovative technology packs food in a vacuum environment by completely excluding air, effectively extending the shelf life of food and ensuring the quality and taste of food. This article will introduce the principle, advantages and application fields of the automatic vacuum food packaging machine in detail.

　　A. Working principle:

　　The automatic vacuum food packaging machine completes the food packaging process through a strict procedure. First, the food to be packaged is placed in the packaging bag, and the mouth of the bag is placed on the sealer. Next, the packaging machine will pump out the air inside the bag to create a vacuum environment. Finally, the sealer completely seals the mouth of the bag by hot pressing or cold pressing to keep the food in an oxygen-free state, thereby realizing long-term freshness of the food.

　　B. Advantages and features:

　　1. Extend the preservation period: the automatic vacuum food packaging machine can effectively extend the preservation period of food, and can extend the preservation time of fresh ingredients several times or even longer. This is an important advantage for food processing plants, restaurants and home users.

　　2. Improve food quality: Vacuum packaging can effectively prevent the oxidation reaction caused by oxygen and slow down the degradation rate of nutrients such as vitamins, fats and proteins in food, thereby maintaining the fresh taste and nutritional content of food.

　　3. Prevent the growth of bacteria: the anaerobic conditions in the vacuum environment can effectively inhibit the growth of bacteria and other microorganisms. Packaging through a fully automatic vacuum food packaging machine can greatly reduce the risk of food contamination by bacteria and ensure food hygiene and safety.

　　4. Improve efficiency: Compared with the traditional manual packaging method, the automatic vacuum food packaging machine is easy and quick to operate, which greatly improves the packaging efficiency. Reduce labor costs and improve production efficiency.

　　C. Application fields:

　　Fully automatic vacuum food packaging machines are currently widely used in various fields, including the following aspects:

　　1. Food processing industry: For the packaging of perishable foods such as meat, aquatic products, and dairy products, the automatic vacuum food packaging machine can extend the shelf life and ensure product quality.

　　2. Catering industry: restaurants, hotels and other places use automatic vacuum food packaging machines to package ingredients, which can effectively control the freshness of ingredients and facilitate storage and distribution.

　　3. Food retail industry: Food retail places such as supermarkets and convenience stores use fully automatic vacuum food packaging machines to provide consumers with fresh food choices and increase product added value.

　　4. Household use: More and more families are buying fully automatic vacuum food packaging machines in order to pack leftover food, prolong storage time and reduce food waste.

　　Fully automatic vacuum food packaging machine is widely used in food processing, catering and retail industries due to its excellent fresh-keeping performance and high-efficiency working method. It not only prolongs the shelf life of food, protects the quality of food, but also reduces the waste of ingredients. With the continuous advancement of technology, it is believed that the automatic vacuum food packaging machine will continue to develop and grow in the future, providing people with more comfortable food preservation solutions.
