Fish food extrusion line is suitable for making floating fish food in various sizes and shapes. So what kind of machinery and equipment are generally used in fish feed production lines? Here's what Darin Machinery tells you:
1. Powder mixer (mixer):
Add a certain proportion of water to the raw corn flour, rice flour, soybean flour, fish meal, meat meal, grain flour, additives, etc. and mix well.
Small fish feed production lines use vertical mixers, and large fish feed production equipment generally use horizontal mixers.
The motor is used for power screw conveying, and the mixed raw materials are conveyed to the feeding hopper of the extruder to ensure convenient and fast feeding.
Small fish feed production lines generally use screw feeders, and large fish feed production machines use bucket lift feeders.
3. Operation platform + storage bin:
Due to the large output of large-scale fish feed production lines, sufficient raw materials must be prepared before each production to supply the production needs. Therefore, general large-scale fish feed production lines use silos to temporarily store mixed raw materials. The wall of the storage bin is made of stainless steel, and vibration motors are installed on both sides of the wall. By adjusting the amplitude of the vibration motor, the problem of raw materials remaining in the storage bin can be effectively avoided.
The operating platform allows workers to observe the storage of raw materials in the silo and the working conditions of the equipment on the platform at any time.
In the high temperature and high pressure environment and the extrusion of the screw, different feeds can be produced by adjusting the process, and the specific particle size and shape can be replaced by the mold. The thickness of the product can be controlled by adjusting the rotational speed of the rotary cutter.
Feed the feed to the roaster. Small production lines need to use positive pressure air conveyors, and large fish feed production lines use high-power negative pressure air conveyors as the source of conveying force.
It is used to lift the baked fish feed pellets into the seasoning line, and the rib structure can effectively prevent the fish feed pellets from falling.
7. Roaster or oven:
Most of them are electric ovens, the temperature is adjusted between 0-200 degrees through the control cabinet, and the interior is a stainless steel double-layer mesh bag, which reduces the moisture of feed particles, promotes the curing rate, and increases the shelf life.
8. Seasoning line:
It is used for the process of seasoning, spraying oil and adding nutritional additives to the dried fish feed pellets. The oil sprayer sprays oil, food attractants, etc. The seasoning drum includes octagonal drum, cylinder, single-roller, and double-roller seasoning line. According to the output and product properties, the oil is sprayed on the surface of the feed, and the minced meat and spices are sprayed at the same time. , spread evenly.
9. Cooling and conveying:
For cooling and final drying of mixed fish feed. Reduce the temperature of frying and feed, promote the solidification of oil, reduce the temperature of pellets, and facilitate packaging. Prevent the occurrence of dampness and hardening after the fish feed is bagged.
10. Vibration screening:
Sieve off excess external material and particles at the end of the year to ensure the quality and the reuse of raw materials.
11. Packaging machine:
Manual sealing machines and automatic packaging machines can be used.
