6-7T/H High Return High Quality Commercial Fish Feed Mill For Floating Fish And Shrimp Feed Production

The feasibility of the commercial fish feed mill for floating fish and shrimp feed production

Aquafeed is an integral part of aquaculture and the most important part of the aquaculture process.

With the stricter and stricter bans on marine juvenile fish in various countries in the future, the price of chilled fish will increase and even be replaced. Moreover, the penetration rate of aquafeed is relatively low, compared with poultry feed and pig feed. Compared with the penetration rate of industrial feed, there is a lot of room for development.

Therefore, it will be the future trend for aquaculture to gradually increase the proportion of feed used. In addition to the promotion of the popularization of aquafeed by environmental protection policies, the advantages of aquafeed itself will inevitably encourage farmers to gradually favor it.

In order to meet the market demand, this 6-7t/h commercial fish feed mill project client, Qingdao Sai Aode Biotechnology Co., Ltd., invested 30 million yuan (4710000USD) in Jiaozhou City to build a commercial aqua shrimp fish feed mill for compound feed production.

Raw materials feeding

The 6-7 tons per hour new build shrimp fish feed mill plant project covers an area of ​​19999.08m² and plans to build two workshops with a construction area of ​​9111.4m². Using the existing office building and workshop of 5945.04m², two new fish shrimp compound feed production lines will be built.

After the commercial fish feed mill for extruded floating fish feed and shrimp prawn feed pellets project is completed, the annual output of complete formula compound feed for fish and shrimp will be 20,000 tons.

Commercial fish feed mill process flow diagram for 6-7 t/h high quality fish and shrimp feed production

  1. Fish meal, soybean meal and flour are all packed in bags and transported by forklift to the feeding port. After manually unpacking, they are put into the lower hopper.

  2. After initial cleaning and sieving to remove impurities and permanent magnet drum to remove iron, they enter the batching bin, and pass the central control according to the fish feed formula. The system accurately batches to the fish feed mixer for first batching and mixing.

  3. The mixed raw materials are transported to the ultra-fine pulverizer by the screw conveyor for ultra-fine secondary pulverization. Various auxiliary materials and fish oil (or soybean oil) are added to the pulverized raw materials for secondary ingredients mixing. After the mixing is completed, the raw materials enter in the fish floating feed extruder machime conditioner.

  4. Then add water and steam (the steam is provided by a gas steam generator, the temperature of the material reaches 100℃-130℃, and the moisture reaches 28%), and the temperature rises during the extrusion process of the twin-screw fish feed extruder for floating feed.

    And the physical and chemical properties of the material occur starch gelatinization and protein denaturation, the instantaneous pressure of extrusion from the die hole drops sharply, the water in the feed is converted from liquid to gaseous state, and it is emitted from the feed to cause the material to expand and form an extruded feed.

  5. The extruded feed is being dried (gas hot air oven), and the dryer removes the moisture of the feed through the flowing hot air to reduce the moisture of the shrimp and fish feed.

  6. After drying, it enters the silo, and the oil pump in the oil injection system provides pressure to atomize the liquid oil and spray it evenly on the fish pellet feed. The fish pellet feed is sent to the cooler and cooled by natural air.

  7. After cooling, the feed is screened, and the qualified products will be automatically weighed and packaged by the extruded feed packaging system if they meet the pellet size;

As an integral part of the fish feed mill production system, dust collectors in the feed industry are not used as environmental protection facilities. Particulate matter is collected by the fish feed mill system's own dust collector and used as raw material, which is not a solid waste.
