How Pet Food Is Made

Typical raw materials used in dog food processing include cereal flours, vegetable proteins, minerals and vitamins, and, in some cases, meat or fish meal and fresh meat. The dry ingredients enter the pre-conditioner + and are steam hydrated. A counter-rotating biaxial unit mixes the ingredients and ensures proper mixing of steam, moisture, and ingredients. The pre-treatment produces a partial pasting of the starch and weaving of the polymer.

The partially cooked mixture is then fed into the twin-screw extruder. Shear, internal temperature, pressure, moisture, and residence time are precisely controlled to achieve optimum starch pasting without loss of food quality. At different stages of the process, liquid or steam can be injected through ports in the extruder barrel. At this stage degassing can be carried out using an exhaust filler.

The granules are then shaped as they are extruded through the die. They are then passed through a dryer to reduce the moisture (usually between 8% and 10%). The product is then coated and flavorings and fats are added before cooling and packaging.

The pet food production line uses high-expansion corn flour grains as the basic raw material, supplemented by bone meal, meat, protein, vitamins, fiber, and other nutrients, and cooperates with a screw extruder to produce pet dog food of different shapes through a strong extrusion and instantaneous expansion molding.

Cat food and other food pellets, and also produce aquatic feed floating feed, mackerel feed pellets, goldfish feed pellets, shrimp feed pellets, crab, mud, bullfrog, and other feeds and foods. The dried flavor coating enhances the taste of the final product, and the final set is automatically packaged. The particle size can be from 0.9-15mm to feed fish of different sizes. Our pet food production line has high output and high-quality products. It is the first choice for large and medium-sized feed processing plants, aquaculture farms, and pet food industries. If you want to get more information about pet food production, welcome to contact us
