Fish feed manufacturing process

There are three fish feed lines in this 48t/h tilapia fish feed factory project, one compound feed production line for fish and two extruded fish feed production lines.

Pelletized fish feed making process

  1. Feeding section

    The types of raw materials used in the project include powders and pellets. The powder does not need to be coarsely pulverized.

    After passing through the scraper conveyor and bucket elevator, it enters the cylinder primary cleaning sieve. After removing large impurities, it enters the permanent magnet cylinder to remove iron impurities and participates in the first batching;

    The granules need to be coarsely pulverized. After passing through the scraper conveyor and bucket elevator, they enter the cylinder primary cleaning screen.

    After removing large impurities, they enter the permanent magnet cylinder to remove iron impurities, and then enter the silo to be pulverized. After coarse crushing, it enters the batching bin through the elevator and distributor to participate in the first batching.

    First coarse pulverization is the pretreatment process of ultrafine pulverization in aquatic feed processing, to ensure stable product quality.

  2. First batching and mixing section

    The first batching is mainly the preparation of public raw materials, that is, the preparation of materials with larger proportions in the tilapia fish food formula. This process is mainly completed by electronic batching scales.

    After the batching is completed, it enters the first mixing. The first batching and mixing is the pretreatment process of ultra-fine pulverization, which can reduce the variation range of material particle size, improve the working condition of the pulverizer, and improve the pulverization efficiency, guarantee the quality of products.

  3. Second crushing section

    Due to the low food intake, short digestive tract and poor digestion ability of aquatic animals, the crushing particle size of aquatic feed is required to be very fine, and the crushing process must be carried out.

    In the secondary crushing process, the primary mixed materials are lifted into the silo to be crushed, and then into the fish feed crusher.

  4. Second mixing section

    Each raw material enters the secondary fish feed mixer after secondary batching. There is an artificial feeding port above the secondary fish feed mixer for the addition of trace additives, and two liquid addition devices are provided on the fish feed mixer, which are used for the addition of oil and molasses respectively.

    In the secondary mixing process, all materials must be fully mixed, and the coefficient of variation CV is less than 5%. After the material is finely pulverized and mixed with secondary ingredients, it enters the granulated material for the granulation and curing process.

  5. Granulation and maturation section

    First, the powdered feed is conditioned with steam or water, and then pressed into columns or other shaped granules by a fish pellet machine, and the material is further matured by adding steam. The pelletizing fish feed pelleting line needs about 2.04t/h of steam, and the water consumption is 16.32m3/d.

  6. Cooling section

    Using the principle of air cooling to cool the product through a pellet feed cooler or cooling tower.

  7. Product Grading and Packaging section

    The cooled fish pellets feed are lifted and crushed into the grading screen for grading. The grading screen is generally composed of two layers of sieves, and the material on the upper sieve needs to be returned to the crusher for crushing;

    The fish feeds under the sieve of the lower sieve is generally fine powder, which can be returned to the silo to be reshaped. The fish feeds pellets on the lower sieve is the finished product, which directly enters the finished product warehouse, and then is weighed and packaged.

  8. Into the finished product warehouse and register section

    The fully packaged finished products are transported to the finished product warehouse for stacking in an orderly manner according to the requirements, and registered in the computer.

Fish feed extrusion process

  1. Feeding section

    The types of raw materials used in the 48t/h tilapia fish feed factory project include powders and pellets. The powder does not need to be coarsely pulverized. After passing through the scraper conveyor and bucket elevator, it enters the cylinder primary cleaning sieve.

    After removing large impurities, it enters the permanent magnet cylinder to remove iron impurities and participates in the first batching;

    The granules need to be coarsely pulverized. After passing through the scraper conveyor and bucket elevator, they enter the cylinder primary cleaning screen.

    After removing large impurities, they enter the permanent magnet cylinder to remove iron impurities, and then enter the silo to be pulverized. After coarse crushing, it enters the batching bin through the elevator and distributor to participate in the first batching.

    First coarse pulverization is the pretreatment process of ultrafine pulverization in aquatic feed processing, work efficiency to ensure stable product quality.

  2. First batching and mixing section

    The first batching is mainly the preparation of public raw materials, that is, the preparation of materials with larger proportions in the tilapia fish food formula. This process is mainly completed by electronic batching scales.

    After the batching is completed, it enters the first mixing. The first batching and mixing is the pretreatment process of ultra-fine pulverization, which can reduce the variation range of material particle size, improve the working condition of the fish feed pulverizer.

  3. Second crushing section

    Due to the low food intake, short digestive tract and poor digestion ability of aquatic animals, the crushing particle size of aquatic feed is required to be very fine, so the crushing process is required.

    In the secondary crushing process, the primary mixed materials are lifted into the silo to be crushed, and then into the crusher. The tiny hairs formed during the process.

  4. Second Mixing section

    Each raw material enters the secondary fish feed mixer after secondary batching. There is an artificial feeding port above the secondary fish feed mixer for the addition of trace additives, and two liquid addition devices are provided on the feed mixer, which are used for the addition of oil and water respectively.

    In the secondary mixing process, all materials must be fully mixed, and the coefficient of variation CV is less than 5%. After the material is finely pulverized and mixed with secondary ingredients, it enters the puffing and drying process.

  5. Tempering and Puffing section

    In the extrusion and puffing process, the material is cooked under high temperature, high humidity and high pressure for a period of time.

    During this process, the physical and chemical properties of the material change drastically (mainly starch gelatinization, protein denaturation), and the material extruded from the die hole, the water in the feed is converted from liquid to gaseous state, and is emitted from the feed, causing the material to expand, forming the so-called extruded feed.

    Because this feed not only has the advantages of general hard pellet feed - good palatability, avoids automatic grading of products and is easy to transport, but also has unique advantages - high degree of starch gelatinization in the feed , protein is easier to digest, reduces waste in feeding process, and improves the utilization rate of animal feed;

    It has excellent floatability, which is convenient for observing the feeding situation of fish and can control water pollution to the greatest extent.

    The steam water consumption added to the product in the raw material expansion process is about 3.65t/h, that is, the water consumption is 29.2m3/d.

  6. Drying section

    The fish feed dryer includes a vertical dryer and a horizontal dryer for fish pellets. After the tilapia fish feed is formed, it will form moist and soft tilapia fish feed (with a moisture content of 25% to 30%). Drying is carried out to reduce the moisture content of the tilapia fish feed to about 13%.

  7. Spraying section

    After the tilapia fish feed is dried, it enters the external spraying system. By coating the surface of the pellet feed with oil, vitamins, flavorings, etc., it can not only meet the energy demand of fish, but also reduce the loss of heat-sensitive substances during processing.

    And it can improve the palatability of the feed and reduce the powder content. After the tilapia fish feed passes through the external spraying system, it needs to be cooled and crumbled.

  8. Cooling section

    Using the principle of air cooling to cool the product through a fish feed pellet cooler or cooling tower.

  9. Product grading and packaging section

    The cooled tilapia fish food are lifted and crushed into the grading screen for grading. The grading screen is generally composed of two layers of sieves. The tilapia fish food on the upper sieve needs to be returned to the crusher for crushing; the tilapia fish food under the sieve of the lower sieve is generally fine powder, which can be returned to the puffing bin for re-forming; the tilapia fish food on the lower sieve is finished products, directly into the finished product warehouse, and then weighed and packaged.

  10. Enter finished goods warehouse and register section

    The complete packaged finished products are transported to the finished product warehouse for stacking in an orderly manner according to the requirements, and registered in the computer.

General floorplan and layout

The main entrance of the large capacity 48t/h tilapia fish feed factory project is set in the east, connected by a factory road to Wenqing Avenue, and a ring lane is set up in the 48t/h tilapia fish feed factory project area to connect with the entrances, exits and walkways of each building.

The 48t/h tilapia fish feed factory project mainly includes two functional areas, namely production workshop and office building. The north side is mainly the green belt and the fish feed factory passage, and the south side is the office building, finished product workshop, main workshop and boiler room, raw material workshop, and living area from east to west.

The 48t/h tilapia fish feed factory production area adopts a combined layout. According to the 48t/h tilapia fish feed factory fish feed production process, the buildings and large outdoor equipment such as raw material input, production and processing, finished product packaging, storage and transportation are reasonably arranged.

Utilities of the 48t/h tilapia fish feed factory
