The comparison of vacuum packaging machine heating device

Is the product vacuum plastic film bag, and then heat sealing glue, can stop the air place such as the oxidation effect. A kind of heat pumping air into vacuum state, sealing, cooling the one-time completed function, apply to food, aquatic products, chemical raw materials, electronic components, precision parts and other products of vacuum sealing, can prevent oxidation, mildew, corrosion, moisture, but also extend the product with good quality fresh storage life of the machine. Hot glue can seal without air leakage of the seal, and is closely related to the heating device. Today, the editor will introduce the structure of the vacuum packaging machine heating device.

the original vacuum packaging machine is with belt and tropical aluminum alloy material for hot glue sealing vacuum packaging machine. Take out of air inside the bag, to the expected after vacuum degree, complete sealing process. Is used widely in food industry, vacuum packaging, all kinds of cooked products, such as chicken, ham, sausages, grilled fillet, beef jerky, etc; Pickled products such as all kinds of pickled vegetables and soy products, dried fruit, etc are used more and more various need fresh food vacuum packaging.

long after vacuum packaging of food freshness, greatly extend the shelf life of food. Then found that the coefficient of thermal expansion and cold contraction coefficient of aluminium alloy is bigger, easy to deformation. And because it is the metal material, you must add water, let a seal after cooling end seal; With phenolic resin to replace imports of nickel alloy heating zone, installed on both ends of the copper pieces of heating device, which can realize the instantaneous heat stability, not deformation, don't need water cooling. Due to the resin itself has the effect of heat preservation, not affected by temperature and change.

our vacuum packing machine in the industry both in appearance and internal structure is relatively high-end, we show that you have to be able to withstand the test of vacuum packing machine and research. If you need it, you can call our sales staff, or you can go to a vacuum packaging machine.
