Common Problems in pet food extrusion machine

 

Common Problem 1: Excessive Operating Noise and Vibration Affect Equipment Lifespan

Under normal circumstances, the operating noise of a pet food making machine should be controlled below 75 decibels. If the noise exceeds 85 decibels or the equipment vibrates significantly, it indicates abnormal operation, often caused by improper installation, loose parts, or insufficient lubrication. Excessive horizontal deviation during installation, or non-compliance of the screw and gearbox coaxiality, will cause severe vibration during operation. Loose screws, bearings, and other components will lead to increased friction and sharp noise during operation. A failed lubrication system will increase the resistance of components, also causing noise and vibration. Emergency Handling: Immediately reduce the screw speed and feed rate. If the vibration and noise do not subside, immediately stop the machine, check for loose parts and lubricant levels, tighten loose parts, replenish lubricant, and perform a no-load test. If the test is successful, then resume production.

 

Common Problem 2: Dog Food Extruder Machine Parameters Fluctuate Excessively, Causing Unstable Operation

Temperature, pressure, and speed are the core operating parameters of a dog food pellet making machine. Under normal circumstances, the fluctuation range should be controlled within ±5%. Frequent fluctuations and instability in these parameters will lead to uneven quality of pet food pellets. This is often caused by sensor malfunction, unstable raw material humidity, or abnormal cooling system. Aging or damage to the temperature sensor can lead to inaccurate temperature detection, frequent start-stop of the heating element, and excessive temperature fluctuations. Raw material humidity deviations exceeding 3% can cause unstable extrusion pressure. A blocked cooling system and poor heat dissipation can cause the barrel temperature to rise continuously, resulting in uncontrolled parameters. Troubleshooting methods: Check the operating status of the temperature and pressure sensors one by one and calibrate them; check the raw material humidity and adjust it to the standard range (15%-18%); clean the cooling system pipes to ensure normal heat dissipation.

 

Common Problem 3: Frequent Equipment Shutdowns Affect Production Continuity

These problems are often caused by the failure to address the above two abnormalities in a timely manner, or by overload protection triggering, and are a serious manifestation of abnormal operation. Frequent shutdowns of the dog food pellet extruder can lead to production interruptions. After restarting, equipment parameters cannot quickly return to stable levels, resulting in a significant drop in the initial production yield of qualified pet food pellets. Furthermore, frequent start-stop cycles exacerbate wear and tear on components such as the motor and screw, increasing maintenance costs. Actual test data shows that frequent shutdowns (more than 3 times per day) can reduce production efficiency by over 30% and the pellet quality qualification rate by 25%. Emergency procedures: After shutdown, thoroughly check for loose components, insufficient lubrication, and abnormal parameters. After rectifying each issue, run the machine idle for 3-5 minutes to confirm stable operation before resuming feeding and production.
