500KG/H Fish Food Production Line

Project overview

The project is a newly built comprehensive compound feed factory, including three types: 500kg/h fish food production line, 1.5t/h pig feed production and 2t/h poultry feed production line. According to the actual needs of customers, under the design and guidance of RICHI engineers, the project adopts the newly designed crushing first and then batching (fish feed processing) and the dual process of batching and crushing (pig and poultry feed production).

In June 2017, at the same time as the new feed production line was built, the customer’s feed company was also established. Like many of our other customers, wanting to produce multiple feeds with one production line is a common requirement. Because the variety of products increases, the profit point of the feed mill will increase.

Even if the output is small, for many areas, the total output of 4 tons per hour is completely enough to supply the surrounding farmers. If you don’t have much capital, but you want to use one production line to process multiple feeds, please feel free to consult Richi Machinery, we will provide you with affordable feed production line solutions.

The type of feed processing chosen by the client for this 500kg/h fish food production line project is the development trend of the feed industry in the future – diversification of categories, not just one kind of feed. Especially for livestock and poultry feed factories, many of them have started to build new aquatic feed factories in recent years to enrich their product types. (Hot products: sinking fish feed machine)

500KG Fish Food Production Line Site

Regarding this point, no matter what kind of feed processing field you want to get involved in, “diversification” should be your long-term plan. (There are indeed some special circumstances, such as special feed processing. This type of feed is currently the type of feed with the best prospects and the best revenue. A small number of manufacturers can achieve high profitability by only operating one type of feed.)

If you also want to invest in a new fish feeds production line with the same output, you can consider the budget, local market conditions, raw materials and formula, etc. For the initial investment, you can invest in a very simple fish feed pellet production line.

If the budget is sufficient, you want to have a long-term vision in the field of feed processing development, or investment in production lines and equipment with greater output, we can customize according to the actual needs of customers. Regardless of the size of your output, regardless of the budget, as long as it is within our technical scope, Richi Machinery will definitely provide you with satisfactory project design, equipment quality and after-sales service.

Process design of 500 kg/h fish food production line

Outsourced raw materials that meet the production requirements, some are stored in the raw material warehouse for standby, and the rest are directly unloaded into the raw material feeding port, sent to the bucket elevator through the conveyor to the upper part of the main workshop for initial cleaning to remove impurities.

And the raw materials sent to the the silo is used for standby, corn and other granular raw materials are crushed by a fish feed pulverizer in the crushing section. After crushing, the corn is subjected to high temperature and high pressure and then decompressed.

Using the expansion characteristics of the corn itself and the instantaneous evaporation of its internal water, the organizational structure and physical and chemical properties of the corn are improved.

500KG Fish Food Production Line Process Flow

According to the ratio of the feed formula, all powdery raw materials (including feed additives) are electronically metered from their respective intermediate silos and sent to the mixer for full mixing, and the mixed powdery feed enters the silo to be granulated for use.

The powdery material is fed into the fish feed pellet machine and steamed for granulation. After granulation, it is cooled to room temperature by a counter-current cooler, and then crushed into finished products by a fish feed crusher. (May be you are interested in: floating fish feed mill)
