  • The adaptability of raw materials is wider, and it can adapt to the processing of high viscosity, low viscosity, high oil content, high moisture or viscous, oily and very wet materials. It can be applied to the processing of various fish feed, shrimp feed, pet feed, livestock and poultry feed.
  • There are fewer restrictions on the particle size of raw materials, and it can be adapted to the processing of raw materials with a wide particle size or from fine powder to coarse powder particles and raw materials with particle sizes outside the specific range of single-screw processing.
  • The material flow is more uniform in the barrel, which can achieve a more accurate ratio and achieve the actual demand regardless of the addition of steam, water and other auxiliary processes.
  • The internal and external quality of the floating fish feed extruder machine is better, which can achieve a very good homogeneous state and make the molecular structure of the material evenly arranged, the surface is smooth during the extrusion molding process, and the product particles have high uniformity and good uniformity.
  • The effect of ripening and homogenization is better. Usually, the degree of starch ripening can reach more than 95%, so that the processed aquatic feed can remain stable in water and the nutritional content of the product will not be lost, and it is easy to digest and absorb.

  • The output is higher under the same power, and the good mixing performance can homogenize the heat obtained by the material in time, accelerate the ripening degree of the material, reduce the fluctuation of the material temperature, and increase the output of extruded products.
  • The floating fish feed extruder machine diversity and adaptability are wider, and it can process granular aquatic feed, high-oil formula, high-moisture, high-cohesive products, and multi-color, sandwich, and special-shaped products.
  • The process operation is more convenient, and the spindle speed can be adjusted according to the needs of the processed products. Due to the self-cleaning feature, the cleaning is very convenient, and there is no need to disassemble the equipment after each processing.
  • The wearing parts are lighter. It is usually a misconception that the wear of the single screw is less. In fact, due to the stable material transportation and material flow characteristics in the twin-screw extrusion process, the material’s impact on the screw and barrel is determined. The wear of the inner sleeve is smaller than that of the single screw. Although there is one more set than the number of screws, the cost of accessories is still lower than that of the single screw.
  • The feed production cost is lower. Due to the good operational stability of the twin-screw model, in the process of feed processing, there is less start-up cost, less waste of water and air, less man-hours, high heat transfer efficiency, high yield, and kWh The output index is high, and the cost of accessories is also low, and its final production cost is still much lower than that of single screw.

Nowadays, most of the world’s aquatic feed production adopts extrusion processing technology, and more and more feed processing enterprises are gradually replacing traditional pellet mills with extrusion fish feed extruders to produce aquatic feed and other special feeds.

In the aquatic feed market in some countries, because most aquatic feed production enterprises are limited by investment funds, they usually choose low-price single-screw extrusion extruders.

But because of their simple structure, technical level, and low manufacturing level, they can only In aquatic feed processing, it is used to produce low-grade floating feed for freshwater fish, but it is difficult to produce submerged feed and other high-grade aquatic feed products.

Although some imported single-screw models can satisfy the production of high-grade submerged feed products, their prices are too high and there is no good cost performance.

Therefore, when customers choose extrusion equipment, they should not only see that the price of twin-screw extruders is higher than that of single-screw extruders, but should also consider the comprehensive cost performance and the cost of producing per ton of products.

RICHI’s high-quality twin-screw floating fish feed extruder machine has reached a certain advanced level in terms of technical performance and manufacturing level. Although the price is higher than that of ordinary single-screw fish feed extruders, the price is far lower than that of imported single-screw floating feed extruders.

Precautions for the actual operation of extrusion processing

Maturity degree of starch

During the working process of the floating fish feed extruder machine, the ripening degree of starch is very important, which directly affects the feed digestibility of aquatic organisms and improves the stability of feed products in water.

The ripening degree of starch is affected by the type of starch, crushing particle size and processing conditions during processing. The operation of the conditioning device or fish pellet  extruder also has a great influence on the maturity of starch.

  • The selection and operation of the fish feed extruder conditioner is very important, especially to control the residence time of the material in the conditioner ( 2min or more) and the quality of added steam. So that the material reaches a material temperature of 90℃ to 95℃ before entering the extrusion cavity. 
  • And the required moisture is uniform and consistent, and reaches a certain degree of maturity, and the rated mechanical energy is increased during the extrusion process. It can greatly increase the ripening degree of starch.

Floating and sinking materials

The floatability of extruded aquatic feed is directly related to the bulk density of the processed final product. Usually, the bulk density of freshwater floating feed is less than 440g/L, and that of seawater (20℃ seawater, 3% salinity) is less than 480g/L.

fish feed materials

At the exit of the extruder and the outlet of the dryer are the bulk density of the wet material and the bulk density of the dry material respectively. It is impractical to measure the bulk density of the feed product after it is dry, so for any feed formula to know the bulk density of the dry material and the wet material relevance is very important.

The bulk density of the product is affected by the formula and processing parameters. The starch content in the formula has been mentioned above.

During the operation of the floating fish feed extruder machine, the variable parameters of the fish feed extruder include the template opening ratio, flow rate (material, steam , water, additive flow rate), host speed, barrel heating/cooling and material moisture, oil content, rated mechanical energy to achieve the required bulk density for processing.

  • Usually, the opening rate is calculated based on 250mm² /t of floating material, 350mm² /t of slowly sinking feed, and 550mm² /t of sinking feed to calculate the number of openings of various specifications of die hole diameters.
  • The operating moisture of floating feedis generally 21% to 25%. The operating moisture of the submerged material is generally 25% to 30%.

Grease addition

Oil and fat raw materials are the best energy sources for aquatic animals, and 2% to 40% of oil can be added to the formula according to the needs of aquatic organisms.

The source of oil can be obtained from dry materials, vegetable oil or animal oil, such as full-fat soybeans, soybean oil or fish oil.

pellet size for floating Fish Feed extruder

In the actual operation of the twin-screw floating fish feed extruder machine processing technology, it is recommended that the fat content in the formula (the total fat content in the extruder) should be as low as possible or not exceed 12%.

  • This recommended range is because when the oil content exceeds 12%, the fastness of the pellets will be significantly reduced.
  • If the designed feed requires more than 12% oil content, the excess part can be used for external spraying after the feed is dry.
  • It can be added by means of normal pressure or vacuum spraying according to the amount of content to be added.

The oil absorption of external spraying is related to the bulk density of the extrusion puffed product and the spraying method. The vacuum spraying method can achieve a higher oil absorption.

When vacuum spraying, the oil flows into the matrix of the granular material to replace the air in the cell space, and the exterior of the finished product Spraying grease can increase product density.

Processing of small-sized extruded pellet products

  • For products with a die hole diameter less than Φ2.0mm, do not use cotton meal and rapeseed meal or raw materials with high fiber content in the formula, and achieve a certain crushing particle size (100% pass 80 mesh or reach 1/5 of the die hole diameter ).
  • In addition, it is necessary to strengthen the cleaning of impurities during the processing process. Cleaning during the process is very important. Magnetic separation and screening must be strengthened. On the one hand, it can ensure the safe operation of the equipment, and on the other hand, it will greatly reduce the possibility of machine blockage.
  • When processing large pellets and then switching to small pellets, it is necessary to clean up the residues in the process, and pay special attention to the conveying equipment (elevator, scraper conveyor, screw conveyor), the dead corner of the bucket and the quenching and tempering. The container must be cleaned very clean.

With the development and application of RICHI’s high-end special twin-screw machine for aquatic feed, we not only want to manufacture high-quality floating fish feed extruder machines, but also let customers fully understand and give full play to the advantages and characteristics of fish feed extruders. 

So that the process can be processed with the minimum investment and minimum cost. The processing cost is the most ideal feed for aquatic animal breeding, and ultimately allows customers to obtain higher efficiency and greater economic benefits.
