How to improve the filling quality of capsule filling machine

The filling quality of the capsule filling machine is very important. With the strict supervision of the industry, it has also become a very concerned issue for pharmaceutical enterprises. Therefore, the capsule filling machine equipment needs to constantly improve the equipment, optimize the equipment structure, and help pharmaceutical enterprises better production.

"In addition to the quality of the equipment itself, the equipment environment, transportation process, and each station will have an impact on the filling quality." When operating the equipment, users need to pay special attention to several stations of the equipment, including the following parts.

First, automatic capsule filling machine capsule turning and separation station. This station is a capsule feeding and separating mechanism, which aims to send the capsule into the module and separate the capsule body and capsule cap for the next step of drug filling.

Common problems in this station include poor separation, flying cap, etc. the technicians remind that the pressure of vacuum separation should be adjusted appropriately, not too large or too small, flying cap phenomenon will appear too often, too small will cause poor separation phenomenon. At the same time, the capsule must be purchased from the regular factory and pass the inspection.

Second, filling station of powder capsule filling machine. This station mainly controls the filling weight of the capsule content, and the main common problem is that the filling content weight is not stable.

The main reasons include three aspects: first, the metering plate and the lower module are not well aligned, which makes the weight of some finished capsules always light. The technician pointed out that it is not easy to find the problems here. The user must do a good job in the alignment here when assembling and debugging the equipment before production. The second is that the gap between the isolation block on the metering plate and the metering plate is too large, which makes the medicine flow into the metering hole through the gap during filling, resulting in a large weight of the capsule. It is reported that it is better to adjust the gap between the isolation block and the metering plate to 0.05 ~ 0.1mm. If it is too small, it will cause wear to the metering plate and damage the equipment.

In addition, the height of the powder on the measuring plate of the pharmaceutical capsule machine also has a certain impact on the filling weight. If the height of the powder is too low, it will make the powder unable to flow into the measuring hole in time, which will cause the capsule to be lighter. If the height is too high, it will cause too many drugs to flow into the measuring plate, and the weight of the capsule to be heavier.

Third, waste capsule removal station. The function of this station is to discharge the capsules with poor separation from the above station. According to the technicians, the key here is to adjust the vacuum negative pressure, not only to ensure that all the capsules that are not separated can be removed, but also the capsule cap in the upper module can not be sucked away. The capsule with too small vacuum can not be completely removed; the capsule cap will be sucked away when the vacuum is too large, which will cause unnecessary waste and reduce the yield.

Fourth, capsule locking station. This work station is an important step of filling the capsule, which is to cover the capsule body and cap.

The common problems in this station include: the capsule is inserted and split, the main reason is that the upper and lower modules are not well aligned, the capsule body and capsule cap are not on the same central line when the capsule is locked, resulting in damage to the capsule body or capsule cap; the locking state is poor, including capsule shrunken head, capsule damage, separation of the finished capsule body and capsule cap. The main reason for the damaged head and capsule is that the locking length is too short; the separation of capsule body and capsule cap is that the capsule is not locked because the locking length is too long, and the separation of capsule body and capsule cap occurs during the transportation of capsule.

Before commissioning the equipment, the user must measure the locking length of the capsule to ensure that it is within the qualified range, so as to ensure the stable production of the capsule filling machine and ensure the quality of the filling.
