We provide sterile dispensing systems for pharmaceutical companies in various dosage forms, including large infusion solutions, water injections, freeze-dried powder injections, eye drops, and oral liquids. Our products are available in both water-soluble and oil soluble forms. The system adopts a 3D modular design, with a compact, beautiful, and generous appearance. The main materials required for the system, such as tanks, pumps, heat exchangers, filters, valves, pipelines, instruments, etc., are all selected from excellent international and domestic brands to ensure the overall quality of the system. The hardware selection of the equipment control system is based on the widely used standard modules in the world, with Siemens S7-1500 series for PLC and TP1200 Comfort series for HMI touch screen. The design, inspection, and composition of the program comply with the GAMP5 V-model, and the software model is applicable to all S7 PLC systems. The program design was optimized based on GAMP5, which improved the stability of the program and was supported by relevant files to ensure system traceability. The system can achieve fully automatic control of production, cleaning, and sterilization. To test whether the liquid preparation system can stably produce products that meet quality requirements in various possible future situations, the system will be validated. The main activities and tests include risk assessment (RA), design confirmation (DQ), installation confirmation (IQ), and operational confirmation (OQ).
