Description
Technical field
The present invention relates to food packing device fields, and in particular to a kind of controlled atmosphere fresh-keeping packing machine.
Background technique
Controlled atmosphere fresh-keeping packing machine is the foods packing machine using composite gas displacement fresh-keeping package technology.The original of controlled atmospheric packing
Reason is to replace the sky in packing box or packaging bag using fresh-keeping gas (multiple gases are matched by material characteristic to be packaged and mixed)
Gas, the external environment for changing material in wrapper slow down the metabolism of material to inhibit the growth of bacterium, microorganism to multiply
Speed extends the freshness date or shelf life of material.So the fresh-keeping packaging in the fields such as food at present is all via vacuum packet
Gradually development is controlled atmospheric packing to dress, namely packs interior air, gas-control packing device using other fresh-keeping or gas displacement material of guaranteeing the quality
Have the advantages that many traditional vacuums are packed incomparable, gas displacement rate is high, and productivity is higher, but current controlled atmospheric packing
There is also some areas for improvement in structure for machine.
In prior art, currently on the market there are two types of the gas displacements and operation mode of gas-control packing device, one is will
The packing box for containing product is placed in a closed cavity shape grinding tool room, and fresh-keeping gas is poured after first vacuumizing to it, is reused
Packaging film wraps up the open position of packing box, implements jacket, second is that gas bleed formula is taken to replace, i.e., will contain the packaging of product
Box is placed in working chamber, using fresh-keeping gas directly to being rinsed in box with gas original in delivery cassette, is completed gas and is set
Implement jacket after changing.The two respectively has superiority and inferiority, the available higher gas displacement rate of mode one and gas mixing precision, this work
Skill it is of less demanding to production equipment but due to vacuumizing, inflating, three cargo handling operations of jacket be to be completed on same station, equipment
Dust cycle is longer.Mode two is since using operation is vacuumized, gas displacement is not rapider, and productivity is higher, but gas
Replacement rate, gas mixing precision are low, influence product fresh-keeping effect, while more demanding to production equipment.
For first vacuumizing, after pour for the manner of packing of fresh-keeping gas, vacuumize fill fresh-keeping gas can will be entirely true
Empty room is full of, and after jacket, remaining fresh-keeping gas is not entered in packaging bag in vacuum chamber, and remaining fresh-keeping gas just discharges after die sinking
Into atmosphere, all slattern.Therefore such manner of packing can waste a large amount of fresh-keeping gas.
A kind of gas-control packing device described in prior art CN201210120399, including rack and is placed in rack
