Common Problems When Using a Wet Dog Food Extruder Machine

 

Particle breakage and poor water resistance: Parameter and formula optimization. The core cause is excessively low extruder temperature (<80℃), insufficient starch gelatinization, or insufficient starch content (<25%). Solutions: Increase the wet dog food maker machine temperature to 85-100℃, adjust the pressure to 3-4MPa, and extend the material maturation time; optimize the formula, increasing the proportion of corn flour and wheat flour to 25%-30%, and perform a simple coating treatment after extrusion to improve particle stability and prevent rapid breakage in water.

 

Wet pet food extruder machine die head clogging: Raw material and operational adjustments. Often caused by excessively high raw material moisture content (>35%), excessively coarse particle size, or premature mixing of oil into the material. Emergency Handling: Immediately stop the machine and cool it down. Disassemble the extruder die head, clean residual material with special tools, and check the wear of the die head aperture. Preventive Measures: Control the moisture content of the raw materials to 30%-35%, ensure a particle size ≥100 mesh, use a post-addition process for oils, and preheat the extruder to the set temperature before starting to avoid adhesion caused by low-temperature feeding.

 

Severe Nutritional Loss in Finished Product: Fine-tune the wet dog food pellet machine process. If vitamins and probiotic activity are insufficient, it is often due to excessively high extruder temperature (>100℃) or excessively long sterilization time. Solution: Reduce the extruder temperature to 70-85℃, adopt a combined "low-temperature extrusion + low-temperature sterilization" process, control the sterilization temperature at 70-75℃, and shorten the time to within 15 minutes; use a post-addition process for heat-sensitive additives, mixing them in after extrusion cooling, and simultaneously calibrate the extruder temperature control sensor to ensure accurate and stable temperature.

 

 

 

 

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!!!
