Precision Operation and Long-lasting Performance: Essential Guidelines for Liquid Filling and Sealing Machines

As a critical piece of precision equipment in industries such as beverages and condiments, the stable operation of liquid filling and sealing machines directly impacts production safety, efficiency, and cost. To ensure they remain in optimal condition long-term, strict protocols must be followed in operation, maintenance, and management, with key focus on the following aspects.

I. Startup and Operation: Procedure First, Calibration Essential

Rigorous preparation before formal production is crucial. Parameters such as fill volume, sealing temperature, pressure, and speed must be precisely adjusted based on the characteristics (e.g., viscosity, gas content) of the batch and the specifications of the packaging containers. Key calibrations include the immersion depth of the filling nozzles and the retraction function to prevent dripping or oxidation. Upon startup, a low-speed no-load test run must be performed to confirm mechanical actions are coordinated and free of abnormal noises. Manually sample the first few dozen products to verify seal integrity (e.g., via vacuum testing) and filling accuracy. Only after meeting standards should the machine speed be increased for batch production.

II. Production Process: Dynamic Monitoring, Timely Intervention

During operation, personnel must maintain constant vigilance. Regularly sample finished products (e.g., every 30–60 minutes) to monitor whether fill level deviations remain within tolerance, and carefully inspect the appearance of seals for smoothness and the clarity/completeness of sealing impressions. Simultaneously, closely monitor equipment status: Is pump pressure stable? Are temperature control readings normal? Are there any unusual noises or vibrations? For liquids containing sugar or corrosive substances, watch for signs of crystallization or clogging in filling valves and delivery lines, and clean promptly per procedure. Any minor deviation should be corrected immediately; operating the equipment in a compromised state is strictly prohibited.

III. Maintenance and Cleaning: Thorough Care, Zero Contamination

Thorough cleaning and maintenance after each production day are fundamental to equipment longevity and food safety. Strictly execute Clean-in-Place (CIP) or disassembly cleaning procedures to ensure all liquid-contact parts—such as storage tanks, pipes, filling valves, and sealing head molds—are free from residue and hard-to-reach contaminants. Pay special attention to the condition of wear-prone parts like sealing rings and replace them promptly. Perform in-depth maintenance regularly (according to weekly/monthly schedules), including applying food-grade lubricants to moving parts, inspecting motors and pneumatic systems, calibrating sensors, etc. Maintain detailed maintenance records.

IV. Safety and Management: System Safeguards, Skill Enhancement

All operations and maintenance must adhere to lockout/tagout procedures to prevent accidental startup and injuries. Enterprises should establish comprehensive Standard Operating Procedures (SOPs), Preventive Maintenance Plans (PMPs), and equipment management files. Equally important is providing ongoing professional training and assessment for operational and maintenance personnel, ensuring they not only know how to operate the equipment but also understand its principles, can identify risks, and master emergency response skills.

In summary, the exceptional performance of liquid filling and sealing machines relies on meticulous daily operations, rigorous monitoring and maintenance, and a scientific, systematic management approach. Only by integrating precision care into every production detail can we ensure these machines operate efficiently, stably, and durably, laying a solid foundation for high-quality production.
