Pet food extrusion process production line is a new technological plan to capture the developing pet food market. The pet food production line mainly uses corn, fish meal, meat meal and some food additives as the main raw materials to obtain the final puffed pet food through mixing, extrusion, baking and seasoning.

• Mixing system

Mixing is an important step in pet food. Once all the ingredients are ready, add them to the blender and blend.

•  Extrusion process

Extrusion is a heat treatment process with high temperature and short time. Not only can it reduce nutrient breakdown in food, improve protein and starch digestibility, but it can also destroy anti-nutrients and microorganisms. It can form round, square, flower, skeletal shapes and other dry pet food shapes using the different molds (shapes) of the food extruder. In pet food preparation, fat is often added to improve the flavor of pet food, which is done during processing. In addition, to give pet food formulas different colors, manufacturers often add colored water to the extraction chamber.

•  Dry system

The drying section is primarily used to remove moisture from pet food extracts. The extracts have a soft texture and a moisture content of 20-30%. After drying, the moisture content of the finished product is controlled to 8%~10%, which can ensure the preservation of the product for a certain period of time.
