How do I adjust the parameters of a Twin Screw Pet Feed Extruder Machine?

 

Dry Dog/Cat Food: High-Temperature, High-Pressure Extrusion

When producing dry pet food, the twin screw pet pellet making machine maintains a temperature of 140-160℃, a pressure of 4-6MPa, and a screw speed of 350-380 rpm. High temperature and pressure fully extrude the material, forming crisp, porous pellets suitable for the chewing needs of adult dogs and cats. The starch content needs to be 35%-45% to support extrusion. A post-oil spraying process is used to add oil, preventing high-temperature oxidation and improving palatability. The finished product's moisture content is controlled at 10%-12% after drying.

 

Wet Dog/Cat Food: Low-Temperature, Low-Pressure for High Moisture Content

Wet pet food needs to retain more moisture and heat-sensitive nutrients. The twin screw pet food making machine is set to a temperature of 100-120℃, a pressure reduced to 2-4MPa, and a speed of 300-320 rpm. Light extrusion is used to ensure pellet formation, avoiding over-extrusion that could cause breakage. The initial moisture content of the raw materials is controlled at 18%-22%, requiring no further drying. After puffing, the raw materials are directly sterilized and packaged, maintaining a finished product moisture content of 25%-40%, resulting in a soft and chewy texture suitable for puppies, senior pets, and pets with sensitive stomachs.

 

Special Pet Foods: Targeted Parameter Adjustments

Puppy food requires a finer texture and easier digestibility. The Twin Screw Pet Food Processing Machine temperature is lowered to 120-130℃, the die orifice diameter is reduced to 1-2mm, and the rotation speed is slowed to 300-320r/min to reduce pellet hardness. Hypoallergenic pet food eliminates grain ingredients and replaces starch with sweet potato flour, requiring increased pressure to 5-6MPa and a rotation speed of 350-380r/min to ensure stable pellet formation. Prescription foods (such as low-fat and high-protein) have their temperature adjusted according to the nutritional ratio. High-protein formulas can be appropriately cooled by 5-10℃ to avoid excessive protein denaturation.

 

 

 

 

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!!!
