Briefly describe the vial powder filling machine

To understand the vial powder filling machine, we must first understand what is a vial and what is a powder? Vials are different from ampoules.
Vials, a small bottle with a rubber stopper, come in brown, transparent and other types, and are generally made of glass
.

The neck of the bottle is thinner, and the thickness of the neck is the same; the mouth of the bottle is slightly thicker than the neck and slightly thinner than the body of the bottle
.

Generally used as medicinal injection bottles, oral liquid bottles,
etc.

Ampoules, a sealed vial made of high-quality thin glass, are often used to store drugs for injection, vaccines, serum,
etc.

The most common is medical, and the medicines used for drips are generally ampoules
.

The difference between them is that the ampoule bottle is sealed in one body, while the vial is sealed with a rubber stopper and is thicker than the ampoule bottle
.

Vials are generally filled with sterile powders, or lyophilized powders; while ampoules are used for liquid preparations
.

 　　From the concept of the bottle, we know that the vial is filled with powder and freeze-dried powder injection, so the next step is to understand what is the powder injection? Powder can be further divided into freeze-dried products for injection and sterile subpackaged products for injection
.

The former is made by freeze-drying the filled ampoules and then sealed, which is commonly used in biological products; the latter is obtained by sub-packaging the purified sterile powder under aseptic conditions, and is commonly used in antibiotic drugs
.

 　　Drugs made into powder have poor stability and generally do not have a sterilization process, so there are stricter requirements for aseptic operation
.

 　　This machine adopts micro-stepping motor self-priming peristaltic pump, uses microcomputer to control the working time and intermittent time of the pump, quantitative automatic filling, and automatic setting of tube loading time
.

 　　The detailed operation process of the vial powder filling machine is to stack the boxes with empty bottles on the tray of the liquid filling machine.
The empty bottles taken out from the unpacking machine are sent to the bottle washer by another conveyor belt for disinfection and cleaning.
After being inspected by the bottle inspection machine, it will enter the filling machine after meeting the cleaning standard, and the liquid will be filled into the bottle by the four-head automatic liquid filling machine
.

The bottle filled with the material is capped and sealed by the capping machine and transported to the labeling machine for labeling
.
