8T/H Trout Fish Feed Production Line in Russia

Why establish trout extruded feed production project in Russia?

Why start a trout feed processing business in Russia? The construction background of this 8t/h trout fish feed production line in Russia project is relatively complex.

Currently, Russian fish farming companies are suffering from severe feed shortages as major suppliers in Denmark, Norway and Finland refuse to do business with them due to the conflict between Russia and Ukraine. ​

Trout farms in Russia's Karelia region, located on the border with Finland, account for 70 percent of Russia's total trout production and more than half of the country's domestic market.

Why establish a trout extruded feed production project in Russia

About 85% of local aquafeeds were previously imported, mainly from Norway, Denmark and Finland, but now these countries have delayed supplies.

At the same time, Russian domestic trout feed manufacturers will not be able to meet the needs of local trout farming. Even if Russia's feed producers are currently operating at full capacity, they will not be able to meet the needs of trout farmers.

Therefore, in the short term, local aquaculture companies have been looking to cooperate with feed suppliers from Vietnam and China to some countries in Western Europe, Iran and Turkey.

It is precisely based on this market environment that the client of this 8t/h trout fish feed production line in Russia project, an investor, is very optimistic about the prospects of Russian aquatic feed processing, so he invested in this 8t/h trout fish feed plant in Russia and related supporting engineering facilities to specialize in processing aquatic extruded feed products. At this stage, only trout feed is processed.

Russia 8t/h fish feed production line Process design

The process flow of the Russia 8 MT fish feed production line designed by the RICHI engineering team for customers is as follows:


Raw material reception and cleaning

The main raw materials required for engineering production during the operation period are transported into the fish feed factory by vehicle. When receiving the main raw materials, the raw materials that need to be crushed are initially cleaned and screened to remove impurities and magnetic separators are used to remove iron impurities.

If unqualified raw materials are found during the raw material receiving and cleaning process, they will be returned to the supplier.


Crushing section

(2)After cleaning and removing impurities, the main raw and auxiliary materials are crushed by a fish feed crusher. The main pollutants in the crushing process are dust and equipment noise.

The crushing is carried out in a closed crusher, and the dust is processed by a bag dust collector; the crushing equipment is equipped with a shock-absorbing foundation and a muffler.


Ingredients and mixing section

According to the formula requirements of aquatic products, various raw materials participating in the ingredients are weighed and entered into the mixer in turn.


Ultra-fine grinding section

Because the finer the particles, the larger their surface area, the larger the contact area between the digestive juice and them, thereby improving the digestibility of the feed and increasing its nutritional return.


Secondary mixing section

Mix the ultrafinely pulverized raw materials again. The mixing process is carried out in a closed mixer, and the main pollutant is mixing equipment noise.


Extrusion and drying section

The extrusion section mainly introduces the boiler steam into the floating fish feed machine through the steam pipe, and heats and expands the secondary mixed raw and auxiliary materials. Part of the steam enters the material and part of the water vapor is returned.


Drying section

After the material is expanded in the extrusion section, it is loaded into the fish feed dryer for electric drying treatment. The moisture content of the material after drying is about 2%.


Cooling section

After this extrusion and drying process is completed, the feed are sent to the cooling machine for cooling treatment. This section is mainly a closed production, and the production process is controlled through the control center.


Double feed packaging section

Packaged and stored in warehouse, and qualified products are stored for sale or shipment. If it is found through monitoring that the feed does not meet the relevant national standards, it will be sent to a sanitary landfill for destruction as general industrial solid waste.

  • The crushing section, batching mixing section, ultra-fine grinding section and secondary mixing section of this 8t/h trout fish feed production line in Russia project are all carried out in the production equipment.
    There is no open mixing process, and this project is equipped with a gas collection + dust removal system at the relevant positions of each process and equipment. After dust removal treatment, the amount of odor generated is relatively small, and the exhaust gas is mainly dust.
  • A certain amount of steam will be generated during the processes of puffing, drying, and granulation. The steam contains the odor of feed. The complete set of fish feed extruder equipment has been designed to combine puffing, drying, and making during the complete set installation.
    A closed gas collection system is set up for processes such as granulation, and the odorous dust-containing gas generated is processed through a dust collector and then discharged to meet standards.
