Vacuum preservation equipment needs to be placed in a high temperature pot to prevent poisoning

After the food is packaged by the vacuum packaging machine, it needs to be put into a high temperature pot to prevent poisoning. Antiviral foods can achieve a long shelf life. For example, snack foods such as dried beans, chicken feet and beef jerky, as well as sausages, hams, marinated eggs and other products we usually eat, use this packaging process to extend the shelf life of food.

Packaging technology of vacuum fresh-keeping equipment products

Especially for fresh meat, it can ensure that the meat is fresh and tender without discoloration, and it can keep the original color of green vegetables unchanged. However, the shelf life of this fresh food is relatively short, and when stored at temperatures around 0°C, the shelf life can reach 7-10 years. For most vacuum-packed foods, the shelf life can usually reach less than 180 days. The reason why this kind of food can achieve such a long shelf life is related to the packaging process of its products.

The vacuum pump motor of vacuum preservation equipment is not allowed to reverse

Like the baler and shrinker, this machine is powered by 380V. In order to ensure the normal operation of the vacuum pump, the vacuum pump motor is not allowed to reverse. The oil level should be checked frequently. The normal oil level is 1/2 or 3/4 of the oil window. When the oil in the vacuum pump turns black, it should be replaced in time.

Vacuum preservation equipment impurity filter

The impurity filter should be removed and cleaned frequently. After continuous operation for 2-3 months, open the back cover and add lubricating oil to the sliding parts. Add lubricating oil to the connector on the heating rod, depending on the usage. The vacuum packaging machine should be used in an environment where the temperature is -10°C to 50°C, the relative humidity is greater than 85%, and the surrounding air is free of corrosive gases, dust and explosion hazards.
