Oral Liquid Production Line
Equipment Technical Specification Document
Issue Date: 2026-05-08
1. Product Overview
The oral liquid production line is an integrated system designed specifically for the pharmaceutical industry, covering the full production process of oral liquid preparations including compounding, filling, capping, and labeling. The line strictly complies with GMP regulations and adopts a modular design philosophy, allowing flexible configuration according to different capacity requirements.
This production line covers the complete process chain from raw material preparation to finished product output, including compounding system, filtration system, filling system, capping system, labeling system, and inspection system. All units are interconnected through a central control system for data communication and coordinated operation, ensuring traceability and consistency throughout the production process.
The line accommodates oral liquid bottles from 5mL to 500mL with production capacity ranging from 2,000 to 30,000 bottles per hour, meeting all scenarios from small-scale R&D to large-scale commercial production.
2. Working Principle
The process flow of the oral liquid production line is as follows:
1. Compounding Section: Raw materials and purified water are mixed in the compounding tank according to the formulation. The temperature control system ensures precise temperature management for solution homogeneity.
2. Filtration Section: The solution passes through a multi-stage filtration system (pre-filtration → fine filtration → sterile filtration) to remove particles and microorganisms, meeting sterile or low-bioburden requirements.
3. Filling Section: Precision metering is performed using peristaltic pumps or ceramic pumps with filling accuracy of ±0.5%, supporting rapid changeover between bottle types.
4. Capping Section: Capping machines apply screw or roll-over caps with adjustable capping torque to ensure reliable seal integrity.
5. Labeling Section: The automatic labeling machine applies labels with centering, skew detection, and inkjet coding capabilities.
6. Inspection Section: Integrated light inspection or vision inspection systems perform in-line inspection of bottle appearance, fill level, and seal quality, rejecting non-conforming products.
Each section is connected via conveyor belts or star wheels for smooth bottle transfer. The central PLC control system monitors all sections in real time and records critical process parameters, ensuring full production traceability.
