Reasons and solutions for vacuum suction failure of seafood food packaging machine
Foods such as cold seafood and fresh meat have very high vacuum requirements for vacuum skin packaging. When our factory is using the vacuum packaging machine for seafood, sometimes we may encounter that the vacuum packaging of the seafood food packaging machine is not tight, or the vacuum suction of the skin packaging machine is small, the skin packaging machine foams, and the skin The packaging machine is not tightly attached, or the food vacuum packaging film is not tightly attached. What are the causes of such failures? And what is its solution? Today, Guangdong Refengyuan Packaging Information Department uses more than ten years of Fengyuan vacuum skin packaging machine manufacturing experience to tell you how to solve the problem of vacuuming.
1. When the vacuum pump of the seafood food vacuum packaging machine is evacuated to the maximum value, cut off the power supply. We need to watch whether the pointer of the barometer goes back. If so, it is leaking. You need to check where the leak is and then fix it.
2. Check whether the sealing strip around the vacuum chamber is damaged. In some cases, the vacuum pressure is insufficient, and the food packaging film and the food packaging box (fitting box) on the bottom are not sticky.
3. Check if there is any air leakage in the cylinder hole of the vacuum chamber. If available, seal the leak with a sealant.
4. Check if there is air leakage in the place where the wires go out of the heating plate. If necessary, block it with a sealant.
The above are the causes and troubleshooting methods of the vacuum suction packaging machine for seafood (not tight vacuum packaging, the vacuum suction force of the skin packaging machine is small, and the skin packaging machine is blistering). I hope I can help everyone.
