Background of 10 t/h fish feed manufacturing plant
This 10t/h fish feed manufacturing plant project is a typical example of a livestock and poultry feed factory getting involved in aquatic feed processing.
Aquafeed is an indispensable part of aquaculture and can be said to be the most important link in the breeding process. As an industry with broad development prospects, how to seize the opportunity? Every month, RICHI receives inquiries from some livestock and poultry feed manufacturers, wanting to build a new aquatic feed line. Like this customer, he sees the prospect of aquatic feed processing. In the field of feed processing, in order to create greater profits, aquatic feed processing must have the best profit prospects at present.
The feed factory in this project was established on September 28, 2010. The original project was originally planned to be constructed in three phases. The factory covers an area of about 50,000 m², with a building area of 40,578m² and a green area of 11,710m².
The crushing-expansion-mixing-granulation process is used to produce feed, with a designed annual output of 240,000 tons of feed, including 20,000 t/a of concentrated feed, 100,000 t/a of suckling pig feed, and 120,000 t/a of fattening feed. The factory area is mainly composed of production plants and other ancillary facilities.
In order to meet the needs of the market, the company adjusted its development strategy in a timely manner and planned to implement a reconstruction project——10t/h fish feed manufacturing plant.
The original pig feed production line (has been demolished) was rebuilt in the plant of the second phase of the project and converted into a fish feed production line, with soybean meal, corn, rapeseed meal , flour and fish meal are used as raw materials to produce fish feed 10 tons per hour through crushing-expansion-drying-cooling-spraying and other processes. It is estimated that the new investment will be $1.6 million. (Hot products: floating fish feed machine)
Before and after the reconstruction, the land area and construction area of the whole plant remain unchanged, and no new buildings are required. After implementing the reconstruction project of fish feed processing line, the whole plant has one pig feed production line and one fish feed pellet production line, with a designed annual production capacity of 120,000 t/a pig feed and 70,000 t/a fish feed (extruded fish feed and sinking fish pellet feed).
Project content and scale
This reconstruction 10t/h fish feed manufacturing plant project relies on the existing second-phase factory building (covering an area of 7130.84m² and building area of 14886.84m²), occupying the existing pig feed production area of the second phase, transformed into a fish feed production plant, part of the equipment that can be used for fish feed production in the dismantled production line was retained, and re-installed with the newly added production equipment.

Process flow of 10 t/h fish feed manufacturing plant
The process design of the new fish feed pellet production line is as follows:
Raw material receiving stage
Raw materials are pre-cleared.
①Granular raw materials: Throw them from the feeding port to the crushing bin, and then go through the pulverizer for primary crushing, then enter the secondary pulverizer for secondary crushing, and transport the secondary pulverized raw materials to the puffing bin through the elevator.
Some impurities will be produced in the primary cleaning process of raw materials in the reconstruction project, including impurities such as small stones and rhizomes. About 84.6t/a.
②Powdered raw materials: After the first-cleared powdered raw materials and the dust produced by primary and secondary crushing are collected, they are recycled into the puffing bin.
The pulverized raw material is processed by pressurization, heating, humidification and tempering by the extruding system of 10t/h fish feed manufacturing plant, and is extruded out of the die hole by mechanical extrusion, so that the pressure is suddenly reduced and the volume expands to form a kind of bulky and porous feed.
After the raw materials are puffed, they pass through the batching auger, and all of them enter the fish feed mixer for mixing.
Pelleting & cooling stage
The semi-finished product after mixing passes through the elevator and conveying scraper, and enters the silo to be granulated. It is transported to the modulator of the fish feed pelletizer through the feeding auger for high-sensitivity steam modulation, and directly enters the fish feed pelleting machine for granulation after modulation.
The semi-finished product after granulation is cooled by the fish feed pellet cooler, and then transported to the finished product rotary classifying screen by the elevator after cooling, and the semi-finished product is screened. Powdered semi-finished products that do not meet the requirements are returned to the silo to be granulated for re-granulation. （Maybe you are interested in : 8T/H floating fish feed plant）
The granules that meet the requirements are exported and then sprayed. After drying and cooling, they are sprayed onto the feed with a vacuum pump to increase the palatability of the feed.
Finished product packaging stage
Qualified finished products that have been crushed and screened out by grading screens enter the finished product warehouse through the elevator for packaging. Among them, the boiler fuel is natural gas, and the rest of the 10t/h fish feed manufacturing plant equipment uses electric energy.
The environmental protection of the fishery is becoming stricter, the fishing volume is shrinking, the removal of cages and the return of fish to the lake are favorable factors, the development prospects of the aquatic product breeding industry are broad, the aquatic feed industry is expected to share the policy dividend, and the demand is growing steadily.
Especially for mid-to-high-end varieties, downstream farmers may increase the amount of feed fed to increase and accelerate product weight gain, thereby driving demand for feed.
The healthy development of the aquaculture industry is inevitable, and the safety of farmed fish is a must, and the transformation of aquaculture methods has released a huge demand space for compound feed.
With the transformation of traditional aquaculture methods to resource-saving, environment-friendly and quality-oriented modern aquaculture methods, safe, efficient and environment-friendly aquaculture compound feeds have broad market expansion space and will surely become the leading products in the future market.
