Analysis of the core role of the upper and lower modules of capsule filling machine in the pharmaceutical industry
1、 Upper module: Key support for capsule positioning and opening lid
The upper module serves as the front-end component for capsule processing, responsible for precise positioning and stable lid opening functions, laying the foundation for the filling process
1. Capsule directional sorting and delivery
Built in dedicated tracks and guiding structures, automatically organize hollow capsules to ensure consistent cap orientation, and transport them to the workstation through negative pressure or mechanical pushing. The speed is adjustable and suitable for batch processing of capsules of multiple specifications.
2. Separation and fixation of capsule cap body
Separate the capsule cap body through mechanical ejector pin or negative pressure, move the capsule body to the filling station, and temporarily store the cap body in the module card slot; Smooth inner wall treatment and elastic buffering can prevent capsule damage and meet quality requirements.
3. Cleaning and protection adaptation
The contact parts are made of 316L stainless steel or food grade materials, which can be adapted for CIP cleaning. Some modules have sealed structures, meeting the GMP cleanliness requirements of the pharmaceutical workshop.
2、 Next module: Core execution of material filling and capsule closure
The following module focuses on precise filling and cap closure, which directly affects the accuracy and qualification rate of drug dosage:
1. Capsule positioning and fixation
After receiving the separated capsule body, it is stably fixed by the workstation slot and elastic clamping. The slot is customized according to specifications to prevent deviation, tilting, and deformation of the capsule body.
2. Precise filling of multiple dosage forms of materials
Suitable for powder, granule, pellet and other dosage forms: Powder is filled with screw or volumetric measurement, with an accuracy error of ≤± 2%; Particles/pellets are filled with vibration or negative pressure to prevent fragmentation and delamination.
3. Capsule cap closure and output
After filling, drive the capsule body to the closing station, align and press it accurately with the cap body, and ensure no looseness or powder leakage after closing. Finally, export the capsule to the subsequent process.
3、 Collaboration between upper and lower modules: Ensuring pharmaceutical production efficiency and quality
By coordinating the operation of the synchronous transmission system, the opening and filling rates are matched to prevent production stagnation; Modular design facilitates quick replacement, reduces downtime when switching specifications or dosage forms, adapts to multiple varieties and scales of production, and supports efficient and compliant drug production.
