What are the typical faults and fixes for home dog food pellet makers?

Problem 1: Loose granules that easily crumble, resulting in low pellet formation rate. This is the most common problem, primarily caused by improper raw material moisture content or an unbalanced formula. Solution: If the raw material is too dry (moisture < 14%), spray a small amount of water onto it (50-80 ml per kg of raw material), stir well, and then process. If the raw material is too wet (moisture > 18%), spread it out to dry for 20-30 minutes, or add 5%-10% dry corn flour to adjust the moisture content. Simultaneously check the formula to ensure that the proportion of starchy raw materials (corn flour, rice flour) is not less than 20%. Starch improves pellet adhesion; a low proportion leads to looseness.

Problem 2: Clogged feed inlet of the pet food pellet machine, preventing raw material from entering. The main cause is uneven raw material particle size or excessive feeding speed. Solution: Re-sieve the raw material to ensure all particles are below 80 mesh, removing any uncrushed coarse material. Slow down the feeding speed, using intermittent feeding (feeding for 3-5 seconds, then pausing for 1 second) to allow the raw material to fully enter the barrel. If a blockage occurs, immediately stop the machine and disconnect the power. Disassemble the feed inlet and use a special tool to clear the blockage. Do not force the machine to start.

Problem 3: Pellets are too hard, and pets refuse to eat them. The cause is that the small fish feed maker machine's mold compression ratio is too high or the processing temperature is too high. Solution: Replace with a lower compression ratio mold (1:5 compression ratio for dog food, 1:4 compression ratio for cat food); lower the processing temperature, reducing dog food temperature to 75-80℃ and cat food temperature to 65-70℃. After processing, place the pellets in a sealed bag and let them stand for 24 hours to "soften" and reduce hardness, improving palatability.

Problem 4: The small fish feed pellet making machine is too noisy and vibrates violently during operation. The cause is unstable equipment placement or loose parts. Solutions:

Problem 5: Floating Fish Feed Extruder process - Motor overheats and even shuts down automatically. Causes include overload or poor heat dissipation.
Solutions:
Move the equipment to a flat surface. For mini models, install thicker anti-slip mats; for medium models, use expansion bolts for secure mounting. Check the bolts securing the mold, screw, etc., and tighten them with a torque wrench to ensure they are secure. If the noise is still excessive, check the bearings for insufficient lubrication and add an appropriate amount of food-grade lubricant.

Problem 6: Floating Fish Feed Extruder process - Motor overheats severely and may even shut down automatically. Causes include overload or poor heat dissipation.
Solutions: Reduce the processing volume per cycle and avoid prolonged full-load operation (it is recommended to stop for 5 minutes every 30 minutes of operation). Clean the dust from the motor's cooling vents to ensure proper ventilation. If the motor frequently shuts down, check for material blockage or if the mold orifice diameter is too small, causing excessive load. Replace with a larger diameter mold if necessary.

Problem 6: Burnt marks on the pellet surface, resulting in nutrient loss. Causes include excessively high processing temperature or excessively long residence time of the raw material in the barrel. Solutions: 1. Reduce the barrel temperature, observing the change in pellet quality for every 5°C decrease; 2. Increase the screw speed (within the equipment's allowable range) to shorten the residence time of the raw material in the barrel; 3. Clean the barrel promptly after processing to prevent residual raw material from carbonizing and contaminating the new material during the next processing.

Problem 7: Uneven mixing of raw materials in the floating fish extruder machine, resulting in nutritional imbalance in the pellets. The cause is insufficient manual mixing. Solution: For small-scale home processing, use a manual mixer to mix for at least 10 minutes, or mix in batches (mix meat and vegetables first, then add grains); for large-scale processing, it is recommended to purchase a small electric mixer (priced at 200-300 yuan) to ensure a mixing uniformity of over 95%.

 

 

 

 

 

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."
