Update time : 2025-06-27 10:14:18

Oral liquid filling and sealing is a packaging method for liquid medicines, which involves filling the liquid medicine into plastic or glass bottles and sealing the bottle mouths through mechanical equipment to ensure the quality and safety of the medicine. Oral liquid filling production lines are mainly used in the production lines of the pharmaceutical, health care product, and food industries. The main filling process of oral liquid is as follows:
1, Before filling, the liquid medicine must be pre-treated. First, the liquid medicine is mixed with a solvent, and then filtered and tested, etc., to ensure that the quality of the liquid medicine meets the specified standards. The liquid medicine transportation is the first step in the filling process, and its task is to transport the finished liquid medicine from the pharmaceutical equipment to the metering filling machine.
2, The metering filling machine is the most core link in the oral liquid filling process, which is to inject the liquid medicine into the finished packaging container in a certain dose. In the metering filling machine, the process of filling the liquid medicine into the finished packaging container needs to be highly automated and standardized. The main features of the fully automatic filling machine are as follows: 1. The filling machine complies with GMP standards and needs to precisely control the transportation speed and flow of the liquid medicine to ensure the accurate dosage of the medicine. 2. The fully automatic filling machine has sufficient sterilization and cleaning mechanisms to avoid cross-contamination, bacterial growth, and other phenomena. 3. The filling machine needs to have efficient liquid injection technology to quickly and accurately complete the filling of the medicine, saving time and cost.
3, Inspection
The last step is to inspect the filled oral liquid. It mainly includes inspecting the liquid level, capacity, and the sealing of the bottle cap, etc., to determine whether the product quality meets the standards.
4, Packaging the finished oral liquid.
For the filled oral liquid, it is labeled and packaged into cartons.
