Miniature vacuum machine

The internal pumping vacuum machine is composed of vacuum pump, vacuum chamber, heating transformer, heating table, plexiglass plate cover, air bag, solenoid valve, time relay, power indicator light, air switch, vacuum meter, gear switch, emergency stop switch, AC contactor and other components.
It can remove the air in the vacuum bag and seal the mouth of the plastic bag. The Chuangming vacuum machine is suitable for the vacuum packaging of all kinds of food and electronic products. It puts the food into the bag, pulls out the gas in the bag, and completes the sealing and stamping date in one time after reaching the predetermined vacuum degree.
The food is packed into a bag. After the air in the bag reaches a predetermined vacuum, it is filled with nitrogen or other mixed gases. Finally, the sealing and stamping date are completed at one time. Use products filled with gas, (puffed food, bread, fish products, etc.)

External pumping vacuum machine
There are mainly anti-pressure, anti-crushing, anti-air, fresh-keeping and maintenance. 1. Internal pumping vacuum machine: DZD-400/S single chamber vacuum machine, DZD-400/2s double chamber vacuum machine, DZD-500/2S double chamber vacuum machine, DZD-600/2S double chamber vacuum machine, bench vacuum machine, tea vacuum packing machine, Can be solid, liquid, powder, paste food, grain, fruit, pickles, preserved fruit, chemicals, electronic components, precision instrument table, rare metal and other vacuum packaging, packaging effect tight, firm, beautiful.
2. External pumping vacuum machine is mainly divided into VS-600 and VS-600A, and its grade configuration is divided into:
(1) Relay + vacuum generator
(2) Relay + high quality vacuum pump
(3) PLC control + high quality vacuum pump
(4) PLC control + LCD screen + high quality vacuum pump
These four kinds of support are very wide market, but (4) PLC control + LCD + high quality vacuum pump is the most convenient operation at present, higher degree of visualization, the lowest maintenance rate of one. This machine is most suitable for large or unusual items.
Action mechanism
The main function of vacuum packaging is to remove oxygen and various gases in the air, so as to help prevent food deterioration. The principle is relatively simple, because food spoilage is mainly caused by the activities of microorganisms, and most microorganisms (such as mold and yeast) need oxygen to survive, and vacuum packaging is to use this principle, to remove the oxygen in the packaging bag and food cells. Make the micro-matter lose the "living environment". Experiments show that: when the oxygen concentration in the bag is less than 1%, the growth and reproduction rate of microorganisms will decrease sharply, and when the oxygen concentration is less than 0.5%, most microorganisms will be inhibited and stop reproduction. (Note: Vacuum packaging cannot inhibit the reproduction of anaerobic bacteria and the deterioration and discoloration of food caused by enzyme reactions. Therefore, it needs to be combined with other auxiliary methods, such as refrigeration, quick-freezing, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt curing, etc.)
In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum oxygen is to prevent food oxidation, because fat food contains A large number of unsaturated fatty acids, oxidized by the action of oxygen, so that food taste, deterioration, in addition, oxidation also makes vitamin A and C loss, unstable substances in food coloring by the action of oxygen, make the color dark. Therefore, deoxygenation can effectively prevent food spoilage and maintain its color, fragrance, taste and nutritional value. It has great commercial value.
The main function of vacuum aerated packaging is in addition to vacuum packaging, which has the functions of oxygen quality preservation and fresh-keeping. Besides, it also has the functions of compression resistance, shattering resistance, air resistance and fresh-keeping, which can more effectively keep the original color, fragrance, taste, shape and nutritional value of food for a long time. In addition, many foods are not suitable for vacuum packaging and must be filled with vacuum packaging. Such as crunchy and fragile food, easy to caked food, easy to deform oil food, sharp edges or higher hardness will Pierce the packaging bag of food. After the food is packed by vacuum aeration, the aeration pressure inside the bag is greater than the atmospheric pressure outside the bag, which can effectively prevent the food from being crushed and deformed and does not affect the appearance, printing and decoration of the bag.
Vacuum aerated package is filled with nitrogen, carbon dioxide, oxygen or a single gas or a mixture of two or three gases. Its nitrogen is an inert gas, which plays a filling role and keeps the positive pressure inside the bag to prevent the air outside the bag from entering the bag, which plays a protective role on the food. Its carbon dioxide can dissolve in all kinds of fat or water, lead to weak acid carbonic acid, has the activity of inhibiting mold, rotten bacteria and other microorganisms. Its oxygen can inhibit the growth and reproduction of anaerobic bacteria, keep the freshness and color of fruits and vegetables, high concentration of oxygen can make fresh meat keep its bright red.
How to choose the vacuum machine:
1. When purchasing equipment, choose the model first, which type of equipment and the size of your own packaging equipment are cost-effective.
2. Whether the output of the equipment and the strength of the vacuum machine meet their own packaging.
3. Working requirements of vacuum machine, especially vacuum chamber. For example, whether the plexiglass cover and vacuum chamber work smooth solder joints.
4. Vacuum pump problem, general vacuum machine has 20 pumps and 40 pumps, so there will be a great difference in price.
5. The quality market of vacuum machine is almost small, mainly service. So when you buy equipment, even if you buy something, you still have to have a good relationship with the salesperson. People will be more willing to do things for you in the future.
6. Equipment manufacturers try to find a medium-sized company. Large companies will not pay attention to your a small customer, small companies want to do well can have no strength, so choose the company is right.
7 price problem, do not the highest price company, their hard-earned money can not afford to toss, also can not be the cheapest, there must be a trick, the medium price can, a point of price is indeed a point of goods is reasonable.
8. Equipment and mobile phone, their own a little bit of care, gently handle, keep clean, dry, with a 3-5 years no problem, wearing parts of course does not count.
Food drying and other conditions of preservation.
