How to check the vacuum degree of food vacuum packaging machine?

Food vacuum packaging is to put the food into the packaging bag, and extract the air in the packaging bag to reach the predetermined vacuum degree, and then complete the sealing process. In the food industry, vacuum packaging applications are very common, such as a variety of cooked products such as beef jerky, chicken legs, sausages, grilled fish fillets, etc.; pickled products such as a variety of pickles and soy products, preserved fruit and other foods that need to keep fresh The more vacuum packaging is used. The vacuum-packed food has a long shelf life and greatly extends the shelf life of the food. Generally, when users of the food packaging industry purchase vacuum packaging machines , the vacuum requirements of the vacuum packaging machine are relatively high, because when the vacuum packaging machine vacuums the packaging machine, the vacuum can not reach a certain degree of vacuum, the food If the air inside is not cleaned, it will cause the food to deteriorate in advance. How to check the vacuum degree of the vacuum packaging machine? The following is a small series of the Chinese plastic net industry website - Jiuzhi Plastics Co., Ltd. The vacuum degree, the specific detection method is as follows:

1. Put the water (cool water) in a vacuum bag and take a vacuum. Detect the bubbles inside for about 35 seconds. If the bubble is smaller than the rice grain, the pass is not acceptable.

2. The vacuum packaging machine works until the vacuum gauge is turned off to -0.1 to see if the vacuum gauge is leaking.

3. The vacuum pump oil of the vacuum packaging machine should be replaced in time (about once a month). If it cannot be replaced in time, it will affect the vacuum pump, which will affect the vacuum.

The above three points are the Xiaobian Plastics Network's Xiaobian for everyone to introduce how to check the vacuum degree of the vacuum packaging machine. I hope that the contents introduced by Xiaobian can help users who use vacuum packaging machines.

Magnetic Light Rail

Magnetic Track Lighting is more and more popular on the market.But how to choose the thickness of Magnetic Track Rail?

Must be thick enough.

There are 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2.0mm,2.2mm thickness on the market.Normally 2.0 can be used at ease, is more reliable quality

How to select the copper and plastic conductivity strip in the led magnetic rail?

Use flat pure copper as much as you can

The old products, and we saw most of which is round copper wire, brass containing copper in 59% ~ 68%, and the conductive efficiency is enough. But the circular brass with lamps and lanterns hanging round copper conductive point contact area is lesser, easy to contact but not stable.So sometimes when you move the magnetic track lights and lanterns, there will be a shiny bright, but you don't move the lamps and lanterns, Still can be normal and no problem to use.

Our material is pure purple thickened copper strip, which is more stable to protect the lamp chip power supply.

So ,pls do remember to select the pure flat copper strip when you use magnetic Lighting Track Rail .Don't be cheap for your safety.
