Vacuum preservation equipment mechanical pump plays a very important role in packaging machine

1. The residual amount of o2 in the package. The norm in the field is that the oxygen content is below 1%, and the lower the standard value, the better.   

2. Gas mixing accuracy. The deviation of the gas should be less than 2%, if the content is too high, it will cause transformation.   

3. The mechanical pump plays a very important role in the packaging machine. It's critically responsible for getting the gas out of the small box, and that's the stage of deciding whether the extracted gas is neat or not. If it is not pumped cleanly, there will be some gas. Even if the refrigerated gas introduced is of high precision, the actual effect of refrigeration cannot be achieved. Therefore, the selection of the mechanical pump depends on the type of mechanical pump configured by the machine equipment manufacturer.   

4. The flatness and firmness of the sealing of machinery and equipment to prevent folds or bubbles and avoid steam leakage.

Multi-device and multi-system composition of vacuum fresh-keeping equipment

The key is composed of ultrafiltration device, pumping system software, electrical automatic control system, electrical implementation system software, film cutting system, temperature control system software, heat sealing film expansion system software, optical automatic control system and mold shell.

Vacuum preservation equipment reduces the inhalation rate of active ingredients

The modified atmosphere packaging machine for vegetables and fruits is a new type of food preservation technology. It uses defensive mixed gases (usually CO2, N2, O2) to replace the gas in the packaging, and uses various defensive gases to play different effects. Most of the microbial strains that cause food mildew grow and develop, and reduce the inhalation rate of active ingredients, thereby keeping food fresh and increasing the freshness period.
