The outer vacuum packaging machine is composed of the inner vacuum packaging machine . Generally, a vacuum packaging machine without a vacuum chamber is called an external vacuum packaging machine. It is mainly used for large packaging vacuum packaging, not only without the size limitation of the vacuum chamber, but also because it is an oil-free vacuum system. Therefore, the packaging process is safe and hygienic, with low pollution and high efficiency. More and more enterprises are willing to choose external vacuum packaging machines. However, there are some key points to note when choosing an external vacuum packaging machine. First of all, we cannot simply choose a model based on the model, because the food (package) produced by each user is different, then the package size is different, and the technical grade requirements of vacuum packaging are also different, and the work efficiency requirements are also different. Therefore, when purchasing an external vacuum packaging machine, we should finally determine which model is suitable for use according to the characteristics of the user's own product.
For example, determine the product as liquid, solid, powder, colloid, semi-liquid, preserved products, meat cooked food, seafood, etc .; and the size of the packaging bag, including the width of the mouth of the bag, the longitudinal length of the bag, and the height after loading Wait. Generally speaking, the main basis for the user to determine the model is the seal length, double-row spacing, available height of the vacuum chamber, and the production efficiency of the entire vacuum packaging machine.
In addition to determining the ideal model, it also compared the purchase points of external vacuum packaging machines with the equipment quality, price and after-sales service of various manufacturers.
