Common Malfunctions and Solutions in The Pet Food Extrusion Equipment Machine

Common Fault 1: Small cat food making machine clogged, raw materials cannot be discharged. The core reason is that the raw material moisture content is too high (above 15%) or the die orifice diameter is too small. Solution: Immediately disconnect the power and allow it to cool. Use a special cleaning rod to clear the blockage from the die end in reverse. Dry the raw material again to reduce the moisture content to 12%-15%. If the die orifice diameter is too small, replace it with a die with a slightly larger diameter (e.g., from 1mm to 2mm). Prevention Tips: Strictly test the moisture content of the raw materials before production, maintain a uniform feeding speed, and avoid feeding too much material at once.

Common Fault 2: Pellets are not formed, loose and brittle. This is mainly due to insufficient temperature (below 120℃) or insufficient pressure in the dog food manufacturing equipment. Solutions: 1. Extend the preheating time of the extruder to 15-20 minutes to ensure the temperature stabilizes at 120-140℃; reduce the feeding speed (e.g., from 10kg/h to 5-8kg/h) and increase the pressure in the extrusion chamber; appropriately increase the screw speed (from 300r/min to 350r/min) to increase frictional heat generation. If the problem persists after these adjustments, check for wear on the extruder screw; replace it promptly if severely worn.

2. Common Fault 3: The finished product has a burnt smell and is black in color. This is due to the dry dog food making machine temperature being too high (above 160℃) or the screw speed being too slow. Solution: Immediately reduce the extruder temperature to 130-140℃. If the temperature cannot stabilize, check if the temperature controller is malfunctioning and repair it promptly; increase the screw speed to 350-400r/min to accelerate the residence time of the raw material in the extrusion chamber and avoid over-cooking. Simultaneously clean the burnt residue from the extrusion chamber and die head to prevent contamination of subsequent raw materials.

3. Common Fault 4: Uneven particle size. The main problem is a mismatch between the cutter speed and the output speed of the floating fish feed pellet making machine, or uneven wear of the die head orifice. Solutions: Adjust the cutter speed; increase the speed if the output speed is fast, and decrease it if it's slow. Check the die head orifice; if severe wear causes inconsistent orifice sizes, replace the die head promptly. Ensure a stable feed speed to avoid fluctuations in the output speed.

Common Fault 5: Abnormal noise during operation of the small fish feed pellet making machine. This is often due to screw or bearing wear, or loose parts. Solutions: Immediately stop the machine and disconnect the power. Check if the screw is bent or worn, and if the bearings are damaged; repair or replace any faulty parts promptly. Tighten all fixing bolts to ensure secure installation. Regularly adding lubricating oil to the bearings during daily use can reduce this type of fault.

MIKIM's fish feed pellet production lines and supporting machinery offer excellent value for money. Not only are they affordable, eliminating middlemen markups and allowing small and medium-sized enterprises (SMEs) and fish farmers to purchase complete sets of equipment at reasonable costs, but they also boast exceptional efficiency. The fully automated process, from raw material crushing and precise ingredient mixing to extrusion pelleting and maturation, is completed in one continuous flow. This results in high starch gelatinization rates and uniform pellet formation, significantly improving production efficiency and feed quality, truly achieving "low cost, high output." Choosing a MIKIM fish feed pellet production line means enjoying comprehensive pre-sales and after-sales service, including 24-hour online customer support, a one-year warranty on the entire machine, professional on-site installation, commissioning, and maintenance, and a stable supply of spare parts. Customers can buy with confidence and use with peace of mind, with both excellent value and service quality!!!
