In the food industry, vacuum packaging has become very common. Various kinds of cooked products such as chicken leg, ham, sausage, etc. and pickled products such as pickles, soybean products, preserved fruits and other foods which need fresh preservation are increasingly using vacuum packaging. Food packaged in a vacuum has a long shelf life, which greatly extends the shelf life of food. When choosing a vacuum packaging machine, we should not choose only according to the model. In brief, because the food (packaging) produced by each user is not the same, so as the packaging size.
Vacuum vertical packaging machine advantage 1, excluding part of the air (oxygen) in the packaging container, can effectively prevent food decay and metamorphosis. 2. Choosing good barrier (air tightness) packaging materials and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can prevent food from losing weight and odor, and also prevent secondary pollution. 3. The gas inside the vacuum packaging container has been eliminated, which accelerates the heat transfer, which can improve the thermal power and prevent the packaging container from cracking due to the expansion of the gas when heating.
Vertical packaging machine, whether it is domestic equipment or imported vertical packaging machine, the wear and tear of machine parts and small shortcomings are unavoidable. Our factory will share the common problems, causes and treatment methods of the machine here, hoping to help you to a certain extent. 1. Defects of cross-sealing hot roll: poor sealing. Reasons: poor heat dispatch, lack of push spring pressure or uneven pressure. Processing method: The suitable pressure and temperature should be selected according to the thickness and variety of packaging materials used. If the sealing temperature is too high, the sealing will be white. The packaging film at the sealing place is easy to peel off. The pressure of each heat sealing roller is adjusted by pushing spring, and the temperature of the roller is controlled by the temperature controller. There are pressure dispatching buttons at the left and right parts of the horizontal sealing roll, and each dispatching button is composed of push-pillow packaging machine buttons and pull buttons. If only push buttons are used, excessive pressure will be exerted on the hot roll, which will easily lead to poor sealing. Therefore, push buttons and pull buttons should be properly used. The dispatching buttons at the two parts of the horizontal sealing hot roll are installed to avoid uneven transverse force.
