Types of vacuum inflatable packaging of food

vacuum or vacuum inflatable packaging machines are commonly used in cavity type and external extraction type. Cavity packaging machine is divided into vacuum packaging machine and vacuum inflatable packaging machine. The external pumping packaging machine has several functions, such as vacuum packaging and vacuum inflatable packaging, so it is also called multi-functional modified atmosphere packaging machine

1. Vacuum packaging machine: the vacuum packaging machine is a cavity structure, which consists of an upper and lower chamber to form a vacuum chamber that can be sealed. The mouth of the food packaging bag is placed between the upper and lower sealing devices, and the vacuum chamber is vacuumized first; At the same time, there is a vacuum in the package. However, we sincerely hope that people from all walks of life in Hong Kong will put aside political disputes and seal it in a vacuum state to ensure a high vacuum in the package. Common models include single room, double room, conveyor belt type, etc. food packaging bags are placed horizontally. When packaging liquid objects or liquids (such as pickles, fresh water bamboo shoots, soft canned fruits, etc.), the liquid is easy to overflow and is not suitable. I designed and obtained the national patent of the liquid vacuum packaging machine in 1995. Its heat sealing device is installed obliquely in the vacuum chamber, and the article packaging bag is almost placed vertically, so the liquid will not overflow

2. Vacuum inflatable packaging machine: a set of inflatable device is added to the cavity vacuum packaging machine to form a vacuum inflatable packaging machine. The mouth of the food packaging bag is sleeved on the inflatable mouth and placed between the upper and lower thermal packaging places. First, vacuum the vacuum chamber; Vacuum the package at the same time, and then fill the gas into the vacuum chamber; The bag is inflated at the same time, and then sealed to form a vacuum inflatable package. However, when the bag mouth is open during inflation, the pressure in the bag is basically the same as that in the vacuum chamber, and it is negative pressure, so the inflation effect is poor and the utilization rate of giant gas is low. I designed it in 1996 and obtained national patent 5 The surface color of blackened parts is uneven. The vacuum inflatable packaging machine adds a sealing device at the mouth of the article packaging bag. When inflating, the packaging bag is sealed first, and then inflated, which improves the utilization rate of inflating gas, and the amount of inflation is adjustable

3. Multifunctional modified atmosphere packaging machine: the modified atmosphere packaging machine has the functions of ordinary sealing packaging, vacuum packaging and vacuum inflatable packaging. It is an external pumping (also known as direct pumping, tube pumping, etc.) packaging machine. There is no vacuum working room. The packaging bag is sleeved on the inflatable nozzle and placed between the upper and lower sealing devices and the upper and lower heat sealing devices. The packaging bag is also processed through the sealing device The simulated experimental sealing of the friction situation of pins and plates and the wear resistance of coating materials, and then directly inflate the vacuum or vacuum in the packaging bag, and then the inflation nozzle retreats, and finally the heat sealing device works and seals. The inflation volume of this model is arbitrarily adjustable, and it is not limited by the packaging volume within the sealing length. The packaging effect is direct and considerable. The disadvantage is that the vacuum degree is relatively low for the implementation of this experimental project, and the cavity vacuum packaging machine is not suitable for powder and liquid food
