I. Introduction of Dog/Cat/Pet Kibbles
 

Pet dry kibbles for dogs and cats have a low moisture content, usually 3%-11%. It is processed by mixing dry ingredients, wet ingredients and other nutrients together, then extruded and puffed, dried, and seasoned. The pet dog food production line produce dry and precooked kibbles that are easier for pets to chew and digest .

Depending on the recipes and adjusting the extrusion process parameters, this dry pet food production line can produce either ‘complete rations’ that provide all the nutrients pet need for healthy physical functions, or ‘supplementary functional foods’ that provide pet with additional correct nutrition. This twin-screw extrusion can use various combinations of starch/protein sources as raw material to produce pet food with different nutritional structures. Dry ingredients include various grains, vegetable meal, dries chicken meal, poultry by-product meal, dried beef meal and dries fish meal. Wet ingredients include fresh or frozen animal meat or by-products.

Flexibility

1. By adjusting the formulation and the extrusion process parameters of the production line, dry pet kibbles of different hardness, crispness and softening speed when meet water can be produced, so as to produce dog and cat food suitable for all ages.
2. The kibble shape and size can be changed freely according to the extrusion die mounted.
3. Other auxiliary materials such as freeze-dried raw meat granules can be added through the rotating drum line with a weighing system, and mixed evenly with dry kibbles to produce the new type called kibble-meat mixed pet food.

Processing potential

1. By changing the extrusion die, this dog/pet food production line can also produce various aquatic feeds, including fast-settling pellets, slow-settling pellets and floating pellets。
2. Adding a core injection machine, a chew pulling machine, and replacing the extrusion mold, this dog/pet food production line can carry out CO-extrusion process for pet chews and treats.
