The key to the selection of granule packing machine lies in its output and quality

Vacuum or vacuum inflatable packaging machine commonly used two types of cavity type and external pumping 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 air-conditioned packaging machine Vacuum packaging machine: the vacuum packaging machine is of cavity structure, which is composed of upper and lower chambers to form a sealed vacuum studio The mouth of the food packaging bag is placed between the upper and lower sealing devices, and the vacuum chamber is vacuumized first; the packaging bag is vacuumized at the same time, and then sealed under the vacuum state, so as to ensure the high vacuum in the packaging bag Commonly used models are single chamber, double chamber, conveyor belt type, etc food packaging bags are placed horizontally When packaging liquid goods or liquid, the liquid is easy to overflow and is not suitable Vacuum inflatable packaging machine: the cavity type vacuum packaging machine is equipped with a set of inflation device, which is a vacuum inflatable packaging machine The mouth of food packaging bag is covered on the inflation mouth, and placed between the upper and lower thermal packaging First, vacuum the vacuum chamber; at the same time, vacuum in the packaging bag, and then fill the gas into the real empty chamber; at the same time, inflation in the packaging bag, and then sealing, which is a vacuum inflatable packaging However, when the opening of the bag is open, 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 Multi function air-conditioned packaging machine: air-conditioned packaging machine has several functions, such as ordinary sealing packaging, vacuum packaging, vacuum inflatable packaging, and it is an external pumping (also known as direct pumping, pumping, etc.) packaging machine There is no vacuum working room, put the packing bag on the inflation nozzle, and put it between the upper and lower sealing devices and the upper and lower heat sealing devices The packing bag is sealed by the sealing device first, and then directly inflates the vacuum or vacuum in the packing bag, then the inflation nozzle moves backward, and the heat sealing device works after Zui This kind of machine can be adjusted at will It is not limited by the packing volume in the range of sealing length The packing effect is direct and considerable The disadvantage is that the vacuum degree is relatively low compared with the cavity vacuum packing machine, and the powder and liquid food are not suitable At present, domestic pharmaceutical enterprises, as long as they produce proprietary Chinese medicine, generally have granular type, a few have powder powder There are many brands of packaging machines produced in China Compared from function, configuration and various aspects, there are great differences The key to production output and packaging quality is to choose the particle and powder packaging machines suitable for our products.
