The process flow of a production line for producing 1000 kilograms of dog food per hour

With the continuous prosperity of the pet market and the growing demand for pet food, efficient and automated dog food production lines have become an important direction for industry development. The 1000 ton puffed dog food production line has become recognized by many pet food production enterprises for its high efficiency and stable product quality. Next, we will provide a detailed introduction to the process flow of this production line:
1、 Raw material preparation
First of all, we need to prepare various raw materials for the production of expanded dog food, such as corn meal, soybean meal, fish meal, meat meal, additives, etc. These ingredients are mixed in a certain proportion to meet the nutritional needs of dog food.
2、 Mixing materials
The mixer is one of the important equipment in the dog food production line. In the mixer, various raw materials are thoroughly mixed with a certain proportion of water to ensure uniform distribution and full contact of the raw materials, preparing for the subsequent extrusion and expansion process.
3、 Transportation and mixing
The mixed raw materials are transported to the feeding hopper of the twin-screw extruder through conveying equipment. In this process, the feeding machine plays a crucial role, using the motor as the power for spiral conveying, ensuring convenient and fast feeding of raw materials, saving labor, and improving production efficiency.
4、 Extrusion swelling
The twin-screw feed puffing machine is the core equipment of the puffed dog food production line. Here, the mixed raw materials undergo changes in the starch structure of the raw materials under high-temperature and high-pressure environments and twin-screw extrusion, becoming easily absorbed nutrients. By adjusting the speed of the rotary cutting motor, feed pellets of the same size, shape, and length can be produced. The specific particle size and shape can be achieved by changing the mold.
5、 Transportation and drying
The extruded dog food particles are transported to multi-layer ovens for drying through conveying equipment. The purpose of drying is to remove excess moisture from dog food, achieve an appropriate moisture content, and improve the product's preservation and taste.
6、 Oil spraying and seasoning
The dried dog food particles enter the fuel injector for fuel injection treatment. Spraying oil can increase the taste and flavor of dog food, and enhance the appetite of pets. Next, the dog food is seasoned using seasoning equipment to give it a taste that pets love.
7、 Screening and packaging
After oil spraying and seasoning treatment, dog food particles enter the screening equipment to remove unqualified particles and impurities. The qualified products after screening are packaged by a packaging machine to complete the entire production process.
8、 Quality control and testing
Strict quality control and testing of raw materials, semi-finished products, and finished products are required throughout the entire production process. This includes quality control of raw materials, monitoring of key parameters in the production process, and sampling and testing of finished products to ensure product quality and safety.
In summary, the puffed dog food production line with an hourly output of 1000 tons has achieved efficient and automated production through scientific process flow and advanced production equipment. This not only improves production efficiency and product quality, but also provides strong support for the development of the pet food industry.
