Vacuum packing machine is an important equipment for vacuum packing of meat products, which can ensure the preservation of the packed goods in the state of no oxygen and effectively prevent the oxidation and corruption of the goods. In the early 1990s, the main products are imported continuous vacuum packaging machines. But with the expansion of the scale of use, the vacuum packing machine can not meet the needs of the market. By introducing technology, our country designed and manufactured automatic vacuum packing equipment by ourselves, which has been widely used for its advantages such as low cost, simple operation, easy maintenance and reliable function.
1. Structure and working principle
Automatic vacuum packaging equipment is composed of electrical system, vacuum system, thermal bonding system, conveyor system, etc. At work, the machine will be installed after bags on the conveyor belt, use gas electricity control system to make the conveyor to move forward a job position, then vacuum cover down, will seal a vacuum chamber, vacuum pump start work extraction, controlled by the electric contact vacuum table of vacuum, after reaching vacuum degree requirements, by the electric control system for a thermal cooling, and then open to start the next reincarnation. The cycle procedure is as follows: conveyor belt inlet, stop-vacuum pumping, thermal sealing, cooling, degassing, vacuum chamber opening and conveyor belt inlet.
2. Design features
Automatic vacuum packing equipment is a kind of conveyor belt conveyor multi-station continuous production equipment, easy to operate, simple maintenance, widely used, low cost and high efficiency. Its characteristics are described as follows.
2.1 Widely used. After the purchase of the machine, only according to the product requirements to choose different specifications, materials, luster packaging bags can be packed into the products you need, no special mold and packaging materials. The machine also adjusts four tilt positions of 6 degrees,10 degrees,20 degrees and 30 degrees according to the packaging needs of different kinds of products. The conveyor belt can be adjusted from horizontal to 30 degrees. Therefore, the performance of the whole, particle, powder, liquid and other forms of goods for packaging.
2.2 Manipulation convenience. The operator only needs to press the start button, the equipment can continue to operate, and then put the bag of goods on the conveyor belt to press well can be continuous production. Products of different specifications only need to loosen bracket screws and adjust bracket position without special technical training.
2.3 Maintenance of simplicity. Most of the inlet vacuum packers are controlled by computer programs, and the maintenance staff need to be specially trained and equipped with special tools and measuring instruments. Domestic automatic vacuum packaging equipment for contactor and relay control, intuitive line, fault is obvious, ordinary electrician can repair.
2.4 Low cost and high efficiency. Entrance to a continuous vacuum packaging machine usually takes three or four up investment of ten thousand yuan, is relatively high vacuum degree, but the investment is too big, and most of the food, especially the high temperature of products is not very tall to the requirement of vacuum degree, domestic automatic vacuum packaging equipment investment thirty thousand yuan, vacuum degree can reach more than 97%, can be satisfied at room temperature keep the high temperature of flexible packaging products, family dinners, such as quick-frozen food processing needs, and the machine conveyor belt continuous production, high efficiency, single machine single class can produce 1.5 tons 250 grams/bag) products, has a device can be satisfied the needs of the general meat products processing enterprises.
3. Applications in the food industry
Automatic vacuum packaging equipment with its inherent advantages is widely used in the food industry of high temperature flexible packaging products, pickled vegetables and snacks packaging, quick-frozen food packaging and wild vegetables and soybean products packaging.
Although the product produces mountain to come already long, area is broad, but because be restricted by shelf life, the market is restricted. Flexible packaging products, which are sterilized by high temperature after vacuum packaging, are very popular among consumers because of their long shelf life and convenience. General requirements of the vacuum up to 94% can be, automatic vacuum packaging equipment vacuum up to 97% above, and sealing quality is not chaotic, suitable for large-scale processing production.
3.2 Packing of pickled vegetables and light meals. In the increasingly developed market economy,
The pace of life is gradually accelerating today, lo CAI and luncheonette with its attractive luster, delicious taste, nutrition justice, quick and convenient and popular with the pan Bo salaried class. The automatic vacuum packaging equipment can be adjusted by the working department, which is suitable for packaging soup and dishes. After the vacuum packaging, it can extend the shelf life while keeping the taste unchanged. It is more suitable for the chain operation of famous stores.
3.3 Quick-frozen food packaging. The automatic vacuum packaging equipment is used for meat balls, meat paste products and other food that need vacuum packaging to be stored. These food can be frozen quickly after vacuum packaging and stored at low temperature, which, on the one hand, can keep the food fresh and have a certain shelf life; on the other hand, it can ensure the product hygiene and prevent pollution.
