How to extend the lifespan of pet food extrusion equipment? - Knowledge

content

Daily maintenance and preventative checks are fundamental to avoiding unexpected malfunctions. Key points include equipment cleaning, parameter checks, and component tightening. After production, the feed hopper, screw, die, and extrusion chamber of the small cat food making machine must be cleaned promptly. Remove the die and screw, and use a soft brush with warm water to remove any residual raw materials to prevent bacterial growth or impact on subsequent production. After cleaning, check the screw and die for wear; record any minor wear, and replace severely worn parts immediately. Simultaneously, check the temperature controller and pressure sensor displays for normal operation. Run the equipment for 5 minutes to observe for any abnormal noises or vibrations. Tighten all screws to prevent loosening and instability.

Weekly maintenance focuses on lubrication and transmission system checks. Lubricate the rotating parts of the extruder, such as bearings and screw shafts. For small pet food extrusion machines, it is recommended to use high-temperature resistant lubricating oil. Control the amount of oil added to each part according to the equipment manual to avoid over- or under-lubrication. Check the tension and wear of the drive belts; adjust them promptly if they are loose, and replace them if cracks or aging are found. Clean the heat sinks of the motor and reducer to ensure good heat dissipation and prevent motor overheating. In addition, sample feed pellets weekly for quality testing. The pellet condition helps determine the stability of the extruder parameters. If slight poor pelleting occurs, adjust parameters such as temperature and speed promptly to prevent small problems from escalating into major malfunctions.

Monthly maintenance requires a comprehensive inspection of all components and parameter calibration. Check the wear of the screw and measure the thickness of the screw threads. If the wear exceeds 2mm, replace it. Check if the die head bore is deformed. Measure the bore size with calipers; if the error exceeds 0.1mm, replace it. Calibrate the temperature and pressure sensors to ensure accurate measurements. If the calibration is unsatisfactory, repair or replace them. Conduct a comprehensive inspection of the equipment's electrical system, checking for aging wiring, poor contact, and dust accumulation in the control cabinet. Clean and repair as needed. Establish a maintenance log to record the content of each maintenance, the parts replaced, and parameter adjustments for easy traceability during subsequent troubleshooting. Through systematic daily maintenance and preventative troubleshooting, the failure rate of the extruder can be reduced by more than 60%, significantly improving production efficiency.
