Know how to use two-compartment vacuum packing machine

Vacuum packaging is to put the food into the packaging bag, draw out the air in the packaging bag, and complete the sealing process after reaching the predetermined vacuum degree.Double-chamber vacuum packing machine is the upper studio that can swing from side to side. When working on one side, products can be placed on the other side, and then work continuously on the other side after the end of the work, and then repeat the cycle.

Double chamber vacuum packing machine is suitable for all kinds of plastic composite film bag or aluminum foil composite film bag, which can pack all kinds of raw and cooked foods, fruits, native products, medicinal materials, chemicals, precision instruments, clothing, hardware products, electronic original devices and other solid, powdery objects, semi-fluid and liquid in vacuum.

Before understanding the use of two-chamber vacuum packaging machine, we should first understand the working principle of two-chamber vacuum packaging machine:

First of all, the vacuum chamber is closed and the vacuum pump works. The vacuum chamber starts to be vacuum-pumped. At the same time, the vacuum meter pointer rises to reach the rated vacuum degree (controlled by time relay ISJ).At the same time of vacuum work, two three-way solenoid valve IDT work, heat sealing gas chamber vacuum, hot pressure frame remains in place;

Secondly, the IDT is broken, and the external atmosphere enters the heat-sealing gas chamber through the upper air inlet. The pressure difference between the vacuum chamber and the heat-sealing gas chamber is used to inflate and expand the heat-sealing gas chamber, so that the upper hot-pressing frame is moved down to press the bag mouth.At the same time, the heat seal transformer work, start to seal;At the same time, the time relay 2SJ works. After a few seconds, it works and the heat sealing is finished.

Third, two two-way solenoid valve 2DT through, the atmosphere into the vacuum chamber, the vacuum gauge pointer back to zero, hot press relying on the reset spring reset, vacuum chamber open cover;Finally, move the above vacuum chamber to another vacuum chamber, that is, enter the next working process, the left and right Chambers work alternately, and the cycle is repeated.Namely vacuum - heat seal - return - cycle.The following small series take you to know how to use the two-chamber vacuum packing machine in detail:

One: connect the power supply to ensure that the vacuum pump does not reverse;

2. Set the air extraction time, heating time, and air extraction time. Customers can conduct more experiments.

3: close the cover equipment, vacuum pump began to pull out the air from the studio, when meet the extraction time setting of the vacuum pump stop working, and then the pressure valve opens automatically, balloon inflated, gasbag plate, phenolic board, heating the whole press tight pincer-like device, article can give heating electric heating at the same time, when the packing sealing after complete, heating stop heating in a state of continuous cooling and air bleed valve automatically open, into the air, open, complete a work cycle.

The extraction time of different products is different. The extraction time of two-chamber vacuum packaging machine is adjustable from 0 to 99.9 seconds.The air extraction time is different for different bag thickness Settings;In addition, different packaging products need to set different air extraction time to pump the air in the bag clean.Take the vacuum packing of meat products (preferably more than 100 pumps) for example: raw meat takes 17 seconds to pump, while frozen meat takes 10 seconds to pump.

Double chamber vacuum packing machine is made of food grade 304 stainless steel, good sealing, clean, hygienic, beautiful and durable.Meet the requirements of food hygiene and corrosion protection, is to use imported electrical appliances control at the same time with export standard manufacturing and national after-sales support, simple operation, energy saving and environmental protection, packaging products can prevent oxidation, mildew, moth-eaten, damp, can maintain quality and fresh, extend the product life.
