For a long time, RICHI has accumulated rich experience in the pellet production lines construction, and has established cooperative relations with thousands of customers in more than 130 countries and regions, providing complete solutions for animal feed mill plants, aqua feed production lines, wood pellet production line, and agricultural waste biomass pellet production lines, organic fertilizer production line, cat litter production lines, etc., and provide services covering the entire life cycle of products.
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.
The client of this 6-7 tons per hour high quality commercial fish feed mill project directly purchased an idle aqua feed factory area, built a new workshop and a finished product warehouse in the open space of the aqua feed factory area, and transformed the existing workshop into a raw material warehouse.
The automatic shrimp and floating fish feed mill project covers an area of 19,999.08m², and plans to build two new workshops with a construction area of 9,111.4m², using the existing office building and workshop of 5,945.04m².

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.
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.
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.
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.
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.
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.
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.
The electricity for the 6-7t/h commercial fish and shrimp feed mill project is provided by Jiaozhou Power Grid, which can meet the electricity requirements.
The natural gas for the 6-7t/h commercial fish and shrimp feed mill project is provided by the local gas company through pipeline.
The steam required for 6-7t/h commercial fish and shrimp feed mill production is provided by two 0.5t/h gas steam generators.
The 6-7t/h commercial fish and shrimp feed mill workshop does not need to be heated, and the office is heated by air conditioners in winter.
