Description of Various Machines:

  1. Manual Filling Machines:

    • Hand-held Capsule Fillers: Primarily used in small-scale or low-volume operations where capsules are manually filled using a simple device to position the capsule bodies, fill the powder, and close the capsules.

  2. Semi-Automatic Capsule Filling Machines:

    • These machines automate part of the process. The capsule is manually placed, but the powder filling is done automatically using dosing mechanisms like auger filling or tamping pin systems. Capsule sealing and closing may also be assisted manually.

  3. Automatic Capsule Filling Machines:

    • These machines automatically fill the capsules with powder, pellets, or liquids using dosing systems like dosing disks or tamping pins. They can handle large-scale production with high precision and efficiency.

  4. Fully Automatic Capsule Filling Machines:

    • These are sophisticated machines for high-volume production with minimal human involvement. The entire process, including capsule separation, filling, closing, sealing, and even printing, is automated. These machines are capable of filling different types of formulations like powders, pellets, and liquids.

Each type of machine offers varying levels of automation, efficiency, and suitability for different production scales and types of formulations.
