When we talk about the filling process of empty gelatin capsules, it is a very critical and complex manufacturing step. Preparation is crucial. The production environment must maintain extremely high cleanliness standards to ensure that no contaminants or impurities are introduced during the filling process. The filling machine and related tools need to be strictly cleaned and sterilized to ensure the safety and hygiene of capsule filling.

Capsule preparation is also a critical step. Before filling, operators must check each empty gelatin capsule to ensure that they are not broken, deformed or otherwise visible. Only by ensuring that the capsule is intact can the quality of the product after filling be ensured.

The preparation of the drug is the next important step in the filling process. Most of the time, the drug is provided to the filling machine in the form of powder or granules. These drugs are usually carefully prepared according to the precise formula and dosage requirements, and the filling machine will accurately fill the drug into the two hemispheres of each capsule according to the preset parameters.

The operation of the filling machine is the core of the whole process. The filling machine usually adopts a rotating and vibrating mechanism to ensure that the drug is evenly distributed in the capsule. Through a precise control system, the filling machine can ensure that the amount of drug in each capsule reaches the expected precise dosage, which is crucial for the pharmaceutical industry.

Once filling is complete, the next stage is the closing of the capsule. The filling machine automatically and precisely closes the two capsule hemispheres together, usually by applying pressure or heat sealing, to ensure that the capsule is completely sealed and the drug cannot leak out or be contaminated by the external environment.

After filling, the product is usually subjected to strict quality control and inspection. This includes visual inspection, weight inspection and possible other quality control steps to ensure that each filled capsule meets the predetermined quality standards and customer needs. The filling machine itself also requires regular maintenance and cleaning. This includes not only regular cleaning procedures, but also regular mechanical maintenance and calibration to ensure the stability and production efficiency of the filling machine.
