The vacuum cleaner is used to maintain the cleanliness and hygiene of the machine by removing any extra dust or debris from its components. It helps in preventing contamination during the filling operations.

3.How Does A Capsule Filler Work?

Capsule Filler Work

The working principle of capsule filler is based on the electrical and mechanical coordination between different components. First, empty two-piece capsules are loaded into the capsule hopper at the top of the machine, while powders and granules are added to the powder hopper. Then, a vibrating device shakes the capsules so that they fall through the capsule shell silo into a cylinder rod.

At this point, the filling agency is then activated to fill the capsules with powders and granules to a predetermined weight. It contains rotating discs with a lower capsule station which holds the capsule cap and capsule body separately. After filling, any waste is removed and placed back to the recycle device which ensures there is no waste of content or empty powder. Finally, the capsules are locked and the finished product is ejected from the machine ready for package and delivery.

The entire process is automated and monitored by a PLC operation panel and various sensors attached to it. The working speed of the machine can also be adjusted as per requirement through this control system.
