Description

Powder packaging device {POWDER PACKING APPARATUS}

The present invention relates to a powder packaging device.

In general, edible powder (eg, lactic acid bacteria, coffee, grain powder, tea powder, etc.) is stored in a disposable stick bag for easy portability and storage. Such a stick bag is completed through a molding process of molding a packaging film into a container shape in order to store and package the powder, and an input process of putting the powder into the molded stick bag in this way.

Conventionally, there is no automated machine capable of manufacturing and packaging stick bags, so stick bags are first made using packaging film, or already manufactured stick bags are purchased and a certain amount of powder is put there, and then sealed through a sealing machine. This method has been used to manufacture stick bags.

This manual powder packaging method takes a very long time to pack the powder, and since a person puts the powder in a pre-manufactured stick bag, it is difficult to input the correct amount, so there is a problem that the amount of powder input varies for each stick bag. .

In addition, since the powder has to go through a sealing process again after being put into the stick bag, there is a disadvantage in that it is difficult to mass-pack the powder because an excessive process and time are input to pack the powder.
