Key points for the selection of small and medium-sized granule packaging machines for pharmaceutical machinery

At present, domestic pharmaceutical companies, as long as they produce Chinese patent medicines, generally have granules and a few powders. There are many brands of packaging machines produced in China. From the aspects of function, configuration and various aspects, the difference is relatively large. The selection of granule and powder packaging machines suitable for the company's products is the key to production yield and packaging quality.

At present, domestic packaging machines are divided into the form of sealing and can be divided into a splint type and a roller type. From the production capacity, it can be divided into single-row machines and multi-row machines. From the way of film removal, it can be divided into vertical machine and horizontal machine. At present, the main forms of pouch packaging are: three-side seal, four-side seal, and back seal.

Vacuum or vacuum inflatable packaging machines are commonly used in both cavity and external pumping models. The cavity packaging machine is divided into a vacuum packaging machine and a vacuum inflatable packaging machine. The external drawing packaging machine has several functions such as vacuum packaging and vacuum inflation packaging, so it is also called multifunctional air-conditioning packaging machine.

1. Vacuum packaging machine: The vacuum packaging machine is a cavity structure. The upper and lower chambers form a vacuum chamber that can be sealed. The food packaging bag mouth is placed between the upper and lower sealing devices, and the vacuum chamber is first vacuumed. The bag is simultaneously vacuumed and then sealed under vacuum to ensure a high vacuum in the bag. Commonly used models are single-chamber, double-chamber, conveyor belt, etc., food packaging bags are horizontally placed, packaging liquid items or liquids (such as kimchi, water bamboo shoots, fruit soft cans, etc.) when the liquid easily overflows and is not suitable . I designed and obtained the national patent liquid vacuum packaging machine in 1995. The heat sealing device is installed obliquely in the vacuum chamber, and the package of the article is placed in an upright position, and the liquid does not overflow.

2, vacuum inflatable packaging machine: cavity vacuum packaging machine added a set of inflatable device that is a vacuum inflatable packaging machine, food packaging bag mouth on the inflatable nozzle, and placed between the upper and lower heat sealing device, first vacuum chamber Vacuum; vacuum in the bag at the same time, then fill the vacuum chamber with gas; the bag is simultaneously inflated and then sealed to form a vacuum inflatable package. However, when the mouth of the packaging bag is opened when inflated, the pressure inside the packaging bag is substantially equal to that in the vacuum chamber, and it is a negative pressure, so the inflation effect is not good, and the utilization rate of the giant gas is low. I designed and obtained the national patented vacuum inflatable packaging machine in 1996. A sealing device was added at the mouth of the bag of the article. When the bag was inflated, the bag was first sealed and then inflated, which improved the utilization rate of the inflating gas and adjustable the amount of inflation.

3, multi-functional air-conditioning packaging machine: air-conditioning packaging machine has ordinary sealing packaging, vacuum packaging, vacuum inflatable packaging several functions, for external pumping (also known as direct pumping, pumping, etc.) packaging machine, no vacuum studio, The bag is placed 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 first sealed by a sealing device, and then the vacuum or vacuum is directly inflated in the packaging bag, and then the inflation nozzle is inwardly Backward, after the Zui heat sealing device works to seal. The inflation amount of this type of machine can be adjusted arbitrarily, and it is not limited by the packaging volume within the length of the sealing. The packaging effect is directly considerable. The disadvantage is that the vacuum is lower than that of the cavity vacuum packaging machine, and the powder and liquid food are not suitable.
