Selection of medium and small particle packing machine

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 At present, the domestic packaging machine can be divided into splint type and roller type According to the capacity, it can be divided into single train and multi train It can be divided into vertical machine and horizontal machine At present, the main forms of small bag packaging are: three side sealing, four side sealing and back sealing 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 1 Vacuum packaging machine: the vacuum packaging machine is of cavity structure, which consists 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; at the same time, the packaging bag is vacuumized, and then sealed in the vacuum state, so as to ensure the high vacuum in the packaging bag The commonly used models are single room, double room, conveyor belt type, etc food packaging bags are placed horizontally When packaging liquid items or liquids (such as pickles, water shoots, soft canned fruits, etc.), the liquid is easy to overflow and not suitable In 1995, I designed and obtained the national liquid vacuum packaging machine Its heat sealing device is installed in the vacuum chamber obliquely The packing bags of articles are almost placed vertically, and the liquid will not overflow 2 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 the food packaging bag is covered on the inflation mouth and placed between the upper and lower thermal packages First, the vacuum chamber is vacuumized; at the same time, the packaging bag is vacuumized, and then the gas is filled into the vacuum chamber; at the same time, the packaging bag is inflated, and then sealed, 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 In 1996, I designed and obtained the national vacuum inflatable packaging machine A sealing device was added at the mouth of the packaging bag When inflating, the packaging bag was sealed first, and then inflated, which improved the utilization rate of the inflated gas, and the inflation volume was adjustable 3 Multifunctional air-conditioned packaging machine: the air-conditioned packaging machine has several functions, such as 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 studio The packaging bag is covered on the inflation nozzle and placed between the upper and lower sealing devices and the upper and lower heat sealing devices The packaging bag is sealed by the sealing device first, and then Directly inflate the vacuum or vacuum in the packaging bag, then the inflation nozzle moves backward, and the Zui rear heat sealing device works to seal 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.
