Vacuum packaging is a common way of food preservation in the food industry. All kinds of cooked food, pickled products, Pickled vegetables, bean products, preserved fruits and other foods that need to be kept fresh choose vacuum packaging, because the fresh-keeping period of vacuum packaged food can be greatly extended, which is conducive to the long-term storage of these perishable foods

Since 1950, when polyester and polyethylene plastic films were successfully used in vacuum packaging, vacuum packaging technology has developed rapidly. The vacuum packaging technology in China developed from the early 1980s, while the vacuum packaging technology was applied in a small amount in the 1990s. With the promotion of small packaging and the development of supermarkets, its application scope is becoming more and more extensive, even gradually replacing the hard packaging


Many people know that there are two reasons for food deterioration, one is microorganism, and the other is oxidation reaction. Vacuum packaging can reduce the decay and deterioration of packaged food by reducing the oxygen content in the packaging


At present, vacuum packaging machines produced by vacuum packaging machine manufacturers can be divided into four categories from packaging products:


Food vacuum packaging machine: the equipment has its own cooling system, which is strict in temperature control and has high requirements for preservation


Medical vacuum packaging machine: a vacuum form that needs to keep the product for a long time


Vacuum packaging machine for electronic products: the internal metal parts of electronic products are susceptible to moisture, oxidation and discoloration, so the main purpose is to alleviate such defects of electronic products


Tea vacuum packaging machine: It is a machine integrating outer packaging, inner packaging and weighing. Its birth marks the modernization of domestic tea packaging level


In addition, it can also be divided into six types according to its use


1. Single chamber/double chamber vacuum packaging machine: just press the vacuum cover to automatically complete the process of air extraction, sealing, printing, cooling, exhaust, etc.


2. Roller vacuum packaging machine: It needs to manually lay the articles to be packed onto the conveyor belt, and can work continuously.


3. Externally pumped vacuum packaging machine: the operation step is to put the air extraction nozzle into the packaging bag to extract air, take out the air nozzle, and seal it. This equipment is the equipment to put the packaging material outside the vacuum chamber to complete vacuum packaging, mainly used for vacuuming large items


4. Vertical cabinet vacuum packaging machine: the body is made of 304 stainless steel special for equipment, and the control part uses PIC computer version control system. It is mainly used for packaging of small particles, powder, liquid and large packaging objects, with large internal volume. Widely used in feed, chemical, food, electronics and other industries


5. Bag-type vacuum packaging machine: It is specially used for continuous and automatic packaging of various cooked foods such as snacks. It automatically realizes a series of continuous automatic production, such as bag picking, bag loading, code printing, and bag supporting, with high production efficiency and low cost. Before the emergence of feeding bag, most of these small foods were manually loaded, and each operation process was intermittent, which was easy to cause food pollution, high cost and low efficiency


6. The vacuum fully automatic packing machine is applicable to all kinds of plastic aluminum foil composite film and any packaging method of plastic composite film. It can achieve moth-proof, moisture-proof, anti-corrosion, mildew-proof and other types of packaging for all kinds of objects of various shapes
