The raw material goes into the flour mixer after crushing (some raw materials also need one crusher). The mixer blends material into even and fine power, then the screw conveyor transfers the material into a twin-screw extruder. The extruder squeezes the material into pellets, the shape and figure can be changed by different molds. The Air conveyor transfers the pellets into a multi-layer oven, which roasts the pellets, removes the water, and keeps the pellets storing longer. The flavoring line seasons the pellets and increases palatability. The pellets come out from the flavoring line then go into the cooling machine, and get cooled in case of metamorphism. Some customers will also choose to package the final product into bags to sell directly. So we also offer a packing machine as an option.
Mixer. It mixes the powder of the ingredients well. According to the production line to choose different types of mixing machine, there are three types for you to choose.
Screw conveyor. The motor is used for power spiral transmission to ensure convenient and fast feeding.
Twin-screw extruder. The main machine of the whole line, which also decides the capacity of the whole plant. The screw material adopts the alloy steel (38CrMoAL). The raw material can be corn flour, grain flour, meat meal, bone meal, fish meal, etc. The specific product shape can be changed by different molds.
Conveyor. The conveyor sends the feed pellets to the oven, the height of the conveyor is determined according to the oven. Customers also can choose the air conveyor.
Multi-layer oven. The oven is mostly an electric oven, the temperature is between 0-200 degrees through the control cabinet to adjust by itself. The internal of the machine is stainless steel double-mesh belt. Baking time can be adjusted according to the number of layers. It can be three, five, seven layers of stainless steel oven. The baking time will depend on the capacity.
Flavoring line. There are octagonal flavor cylinders, single drums, double drum flavor lines. We will make the configuration according to the specific output and the nature of the product.
Cooling machine. This part adopts a water-cooled circulating drum. Used for preliminary cooling and conveying of products.
