Raw material receiving and cleaning: Raw material receiving includes conveying equipment, magnetic separation equipment, initial screening, measuring equipment, and vertical silos. The commonly used raw material measuring equipment is a weighing scale. Small and medium-sized factories generally do not have two feeding ports for granular and powder materials, while large factories have feeding ports for granular and multiple auxiliary materials. Grain based raw materials such as corn and sorghum enter the silo, while flour is directly fed into the discharge port

Crushing: The crusher is the first process of the production line, mainly used to crush raw materials such as corn, soybeans, and meat powder. Choosing a suitable crusher can improve the utilization rate of raw materials and the uniformity of mixing. For materials with different characteristics, the crusher should have the ability to adjust the fineness to meet the needs of different formulations

Mixing: The main function of the mixer is to evenly mix the crushed raw materials to ensure the balanced nutritional content of dog food. A scientific formula can ensure the balanced nutritional content of dog food, and additives such as vitamins and minerals can be added to improve the health level of pets

Puffing: The twin-screw extrusion puffing machine is the core equipment of the puffing dog food production line, which puffing the mixed raw materials through high temperature and high pressure treatment. During the puffing process, starch is converted into a more easily digestible form, which increases the nutrient absorption rate of dog food. At the same time, the pore structure formed makes dog food more crispy and enhances its taste

Drying: Puffed dog food needs to be dried to reduce moisture and increase its shelf life. The multi-layer mesh belt dryer has the advantages of low energy consumption and uniform drying. It can adjust the air volume and temperature according to different product designs to ensure that dog food is dried reasonably without losing its nutritional content

Seasoning: Finally, automatic seasoning equipment is used to add suitable seasonings to enhance the taste and appeal of the product. Efficient seasoning equipment ensures even seasoning and no waste

Packaging: The cooled feed is packaged into finished products
