How to achieve food packaging machine ideal vacuum degree?
How to achieve food packaging machine ideal vacuum degree? The main working principle of food packing machine is to extend the storage period and storage effect by vacuuming the package. Different packing materials have different requirements for the vacuum degree, some of the strict air requirements of the goods, the use of large power vacuum pump to remove air. However, some customers have reported that the automatic stretch film vacuum packaging machine, which was supposed to have high vacuum capacity, cannot reach the original vacuum after being used for a period of time. What is the reason for this and how to deal with it? Here are some tips:
How to achieve food packaging machine ideal vacuum degree? 1. It is possible that the pump body of the vacuum packing machine has not changed the oil for a long time, or the goods containing water have been packed for a long time, so a small amount of water enters into the oil and causes pollution, which leads to the vacuum pump not working normally and cannot reach the required vacuum degree. Please replace the vacuum pump oil. (if the import pump needs to find manufacturers to buy special pump oil, domestic pumps can use shell). The price of vacuum packing machine is different according to the configuration. Packaging machinery in the stretch film packaging machine is an automatic equipment, the working efficiency is relatively higher.

How to achieve food packaging machine ideal vacuum degree? In the process of using the vacuum packaging machine, it will meet various challenges of actual production conditions. It is very likely that the manufacturers spend a lot of money to buy the vacuum packaging equipment, but due to the production of slight changes in the use of limitations, which requires us to make some changes on the basis of the original equipment, and the common is to adjust the number of seconds of vacuum pumping time. Generally speaking, the vacuum machine has a fixed range of pumping time when it leaves the factory. If it exceeds or fails to reach this range, it needs to adjust the control panel of the vacuum packaging machine by itself. There are two existing methods:
How to achieve food packaging machine ideal vacuum degree? 1, replace the original computer board control system, such an advantage is simple and convenient, only need to ask the manufacturer to send the computer board, but there are disadvantages: first, after the replacement of the computer board vacuum time is limited, if the existing control panel to adjust the vacuum time, can only be guaranteed in the range of 0.1-9.9 seconds; Second, the heating of vacuum packaging machine will be affected. When the vacuum time is too short, a large amount of air will be left in the vacuum chamber, and the pressure difference of sealing air bag is too small to fully open, resulting in unqualified sealing of packaging bags. In addition, too much oxygen in the vacuum chamber will lead to oxidation in the heating zone of the vacuum machine and increase the failure rate.
How to achieve food packaging machine ideal vacuum degree? 2, adjust the vacuum packaging machine control panel is changed to the automatic vacuum machine, the advantage of this is that the automatic computer board can be adjusted in a wider range, ranging from 0.1 to 99.9 seconds, can meet various vacuum requirements. Deficiency is that if the existing machines for replacement, will increase the cost of capital, equipment and as vacuum machine for automatic control panel, vacuum packaging machine corresponding lines need to reconfigure and specifications of different computer board also decided to vacuum packaging equipment appearance is different, need to send to manufacturers for extensive changes.
The above is a brief description of how to achieve ideal vacuum degree for food packaging machine. If your packaging machine is in the same condition and these solutions are still not available, please contact the manufacturer of vacuum packaging machine in time to avoid delay in production.
