Pet Food Production Line is used to produce different kinds of pet food, floating fish feed, and sinking fish feed. It works with simple operation, accurate parameter control. The products can be finished in the stipulated temperature, pressure, humidity and time. Owing to the reasonable design, special materials, the stability, repairs can be guaranteed and ensured. The various shape and taste must meet the different requirements of pet food.
1.2.More details of Pet Food Production Line
A. High quality ingredients (fish meal, cereals, vegetable proteins …) are selected and ground according to the specific nutritional and pellets size requirements of the aquatic animals and various fish request.
B. The particle quantity of fish feed raw material is a key factor for premium granulates production : therefore the grinding step is an important unit operation. The powder is then mixed with minor ingredients such as vitamins, mineral premixes… prior to the preconditioning to the fish extruder directly.
C. Next,the heart of the process, extrusion cooking is done in three stages in the fish feed machine : preconditioning, extrusion cooking and die texturing/ shaping. Twin-screw extrusion-cooking uses its perfect mixing ability and parameters control such as shear, temperature, residence time to reach the highest physical and nutritional standards. Through direct steam injection,venting device and efficient barrel cooling, adjustable screw speed, screw configuration, shear and temperature conditions are perfectly controlled ; this leads to optimized functional and nutritional pellet properties such as the bulk density, calibration,cooking degree, best ratio proteins- lipids, etc
D. Fish feed Pellets can then be oil coated and possible additives and are cooled down to complete the fish feed processing.
