1.Introduction to fish feed production line

The fish feed production line uses whole grains, beans, meat meal, and fish meal as the main raw materials. After extrusion, puffing, drying, and seasoning, the product has a unique taste, rich nutrition, and is easier to absorb.

Layout of Dog Pet Food Processing Machinery Line 00

(a) Mixer: Add a certain proportion of water to the raw materials corn flour, rice flour, soybean meal, fish meal, meat meal, grain flour, additives, etc. and mix them thoroughly.

(b) Feeding machine: The motor is used to power the screw conveyor to transport the mixed raw materials into the feeding hopper of the twin-screw extruder. This equipment is convenient and quick to load materials, saves labor and has high efficiency.

(c) Twin-screw feed extruder: When the mixed raw materials are extruded in a high-temperature, high-pressure environment and twin-screws, the starch structure in the raw materials changes and becomes easily absorbed nutrients, which are extruded through the feed die and adjusted to rotate. The speed of the motor is adjusted until the feed particles are of the same size and length. The specific particle size and shape are obtained by changing the mold. The feed extruder adopts advanced frequency conversion speed regulation technology, which is more energy-saving and has better speed control. The current and speed of the motor during operation can be directly seen through the frequency converter panel to ensure that the equipment is stable.

(d) Conveyor: transport the produced feed particles to the multi-layer drying equipment.

(e) Multi-layer oven: The oven is divided into electric oven, oil oven, gas oven and steam oven. The temperature is automatically adjusted through the control cabinet. The internal transportation of the oven is stable and the failure rate is low. The feed pellets circulate through multi-layer S-shaped tracks to dry the feed pellets to the moisture content to increase the shelf life.

(f) Spray seasoning line: The oil spray machine sprays oil, attractants, etc. The seasoning cylinders include octagonal cylinders, cylinders, lifting single drums, and double drum seasoning lines. They are configured according to the output and product properties to spray oil on the surface of the feed. Spray the minced meat and spices at the same time and spread evenly. After this process, burrs and burrs on the surface of the feed pellets can also be removed, making the surface of the feed pellets smoother.

(h) Cooling conveyor: lowers the surface temperature of drying feed particles, promotes oil coagulation, lowers the temperature of the particles, and facilitates packaging.

(i) Vibrating screen: Screen out excess external materials and granular residue to ensure quality.
