What food vacuum bag extraction way | how to bleed

Packing bags of food vacuum suction, exhaust, the air inside the bag out as far as possible, form a kind of vacuum of space, make food preservation longer, better. Air is the stand or fall of extraction residue, standard, also directly influences the effect of vacuum packing bag to protect food. So it's very important to extraction, extraction way what then? Current production mechanization, pure manual packing is not applicable, and the effect of vacuum is poor, without the effect of the vacuum pump can't purchase and meet the requirements of food packaging. So small make up today to introduce a pump vacuum extraction method. 【 Vacuum bag] A, semi-automatic extraction vacuum. After packing bag filled with good food, placed on vacuum packaging machine. Note the location of the heat sealing knife when placed, put flush the bag. The suction nozzle in the bag, the operating pressure glue will flatten packet, and then open the vacuum pump, began to smoke. Achieve their need of vacuum requirements, spare suction nozzle, and heat sealing so there are a lot of semi-automatic vacuum packaging machine equipment, the third step can achieve timing function. Can be in baidu search: semi-automatic vacuum packer, outside pumping vacuum packaging machine. Buy equipment can put your food sack after extraction, vacuum achieve them. Second, the fully automatic vacuum suction. Bag after filling, sent to the vacuum chamber. Dandy will flatten bags. Vacuum pump operation, the vacuum of indoor air. To set index, pump stop operation, heat sealing on the knife down, heat sealing. Heat sealing, after the completion of the transfer out of the vacuum chamber. Automatic vacuum packaging machine equipment, there will be a vacuum chamber, without using the suction nozzle, more convenient and quick operation. And in the vacuum chamber to heat sealing, won't have the risk of return air rushed into the bag. Better than the type of vacuum. Above is the small make up summary of food vacuum bag way of extraction, pure manual operation can be reference for semi-automatic way. You need food vacuum bag, remember to packaging customization! 【 Food packaging 】 Tags: food vacuum bag
