The product into the vacuum bag, vacuum bag into the vacuum chamber, pressure cover. Motor driven vacuum pump (referred lambency to in this too, some vacuum drum up slowly, which is due to vacuum suction in the vacuum chamber than slower than the vacuum pressure of the vacuum chamber caused by small), then inflatable air bag sealing lambency strip from the top, the vacuum lambency seal. Finally, lambency the solenoid valve opens, the air inlet to the vacuum packaging items into the airtight container is evacuated before the container is sealed, so that substantially no air within the sealed container as a packaging technology.
Vacuum packing machine Description: Our vacuum packaging technology in the early 1980s developed vacuum packaging technology originated in the 1940s. In 1950, polyester, polyethylene plastic film successfully used vacuum packaging, and filling the vacuum packaging technology in the early 1990s began to use a small amount, with the promotion and development of small supermarket packaging, its scope more widely Some will gradually replace rigid packaging, the prospects are very promising. Thereafter, vacuum packaging lambency has been developing rapidly.
Vacuum packaging machine from the vacuum system, pneumatic system, electrical control system, pneumatic control system. There are three different operating modes. 1, vacuum mode: The heating rod packing items into the exhaust nozzles set into the bag and riding a foot switch heating lambency rod in the cylinder slipped into the role of sponge bag pressed pause vacuum bag (the same as the packer can be pre-set lambency vacuum time upon request) heating gas nozzle back pocket suppress heating rods continue to decline, sealing, cooling heating rods finished lambency restoration lambency to the highest position (vacuum packaging machine to complete a Work loop). 2, inflatable models: the packaging into the exhaust nozzle heating rods and set into the bag once stepped foot switch heating rod in the cylinder slipped into the role of sponge bag pressed pause vacuum bag inflatable cylinder gas nozzle in action backward, heating rods continue to decline heating, sealing, cooling heating rods finished reset vacuum packaging machine to complete a work loop) 3, sealing mode: (can be used as general-sealing machine) will Heater package put a foot switch pedal heating rod in the cylinder role fell to suppress sponge bag, heat sealing, cooling heating rods finished reset (to complete a work loop).
2, the use of barrier (airtight) packaging materials and sealing technology and strict requirements, can effectively prevent the exchange of substances in the package contents can avoid food weight loss, loss of taste, but also to prevent secondary pollution. 3, vacuum-packed container inside the gas has been removed, accelerated heat conduction, which can improve the efficiency of heat sterilization, but also to avoid the heat sterilization, due to the expansion of the gas leaving the containers to rupture. In the food industry, vacuum packaging applications are very common, various cooked products lambency such as chicken, ham, sausage, etc.; various pickles and pickled products such as soy products, dried fruit and other kinds of food preservation increasingly require the use of vacuum lambency packaging. After vacuum-packed food preservation and long, greatly extend the shelf life of food.
Use and maintenance procedures and principles of a vacuum packaging machine, vacuum: a vacuum chamber closing lid, vacuum pump, vacuum chamber to start pumping vacuum packaging bag while the vacuum, vacuum gauge pointer to rise, reaching rated vacuum (by the time relay ISJ control) vacuum pump to stop working, stop the vacuum. While working in a vacuum, two-way solenoid valve IDT work, sealing the vacuum chamber, hot planes remain in place. 2, IDT sealing off the outside air intake hole into the gas chamber through the upper heat-sealing, with the vacuum chamber by the pressure difference between lambency the sealing chamber, lambency sealing the chamber is inflated, pressing it on the shelf down , press and hold the bag; while sealing the transformer and began sealing; In the meantime, time relay 2SJ work, a few seconds after the action, sealing ends. 3, return air: two two-way solenoid valve 2DT through the atmosphere into the vacuum chamber, vacuum gauge pointer lambency back to zero, relying on hot rack return spring reset, the vacuum chamber lid. 4, loop: the vacuum chamber to another chamber that into the next work process, alternating left and right chambers work, ad infinitum. Use and maintenance instructions and precautions of a vacuum packaging machine, check whether the power supply voltage, (three-phase four-wire single-phase 380V or 220V), ground is good, the connector is firmly inside the machine. 2, check the oil level reaches the vacuum pump requirements. (Note: To keep the oil pump oil level 1/2-3/4 regular fuel oil change, oil change once a month of continuous work, such as working environment too much water vapor or dust, you need to shorten the oil change period, with mechanical oil pump or the oil instead of N68. required preheating of the front pump oil change.) according to the needs of the packaging article, is generally lambency adjusted at the time of vacuum around 20-30 seconds (the longer, lambency the higher the degree of vacuum, with the use of area the altitude increases, the maximum vacuum proportionally decreased.) 4, according to the bag material, adjusting the sealing temperature and sealing time. (Note: The longest delay 6 seconds sealing layer composite film temperature is generally in the 2-3 gear adjustment, time adjustment in the first 3-4 seconds of various packaging materials testing its optimum temperature and time with the extension of working hours and appropriate.. reduce stalls or shorten the time.) 5, according to the packaging needs, put the appropriate date of manufacture glue words. 6, the power is turned on to open a lock placed in the "ON" position. One of the vacuum chamber is closed, a little lambency pressure pump to work, you should pay attention to the running direction. Forward That vacuum is established, the reverse does not create a vacuum and must change immediately corrected. 7, the items are uniformly arranged in the bags to the sealing bar, and placed under the pressure of the bag. 8, close to a vacuum chamber, a little pressure, the entire packaging process from the vacuum, sealing, printing, return air automatic process control once completed by the electrical. 9, while the working chamber to a vacuum, the vacuum chamber can be put another article. After returning to be a gas chamber to zero, the vacuum chamber can be moved to another vacuum chamber, so that the left and right chambers alternately work. 10, work process, if found irregularities, according to the emergency stop button, ahead of the return air, back to work. 11, when the work to be suspended, the locking switch in the "off" position when not in use, turn off the power, do the cleaning lambency work.

1, vacuum mode: The heating rod packing items into the exhaust nozzles set into the bag and riding lambency a foot switch heating rod in the cylinder slipped into the role of sponge bag pressed pause vacuum bag (like strapping the same time can be preset vacuum upon request) heating gas nozzle back pocket suppress heating rods continue to decline, sealing, lambency cooling heating rods finished restoration to the highest position (vacuum packaging machine to complete a the duty cycle). lambency
2, inflatable models: the packaging into the exhaust nozzle heating rods and set into the bag once stepped foot switch heating rod in the cylinder slipped into the role of sponge bag pressed pause vacuum bag inflatable cylinder gas nozzle in action backward, heating rods continue to decline heating, sealing, cooling heating rods finished reset (vacuum packaging machine to complete a cycle of work)
3, sealing mode: (can be used as general-sealing machine) heating the packaging lambency into a foot switch pedal rod heating lambency rod in the cylinder role fell to suppress sponge bag, heat sealing, cooling Finished heating rods reset (to complete a cycle of work). Function and principle 3, vacuum packaging machine
The main role of oxygen is vacuum packed in order to help prevent food spoilage, the principle is relatively simple, due to deterioration of food mold rot caused mainly lambency by microbial activity, and most microorganisms (such as yeast and mold) require oxygen for survival , while the vacuum packaging is the use of this
