The wet-process fish feed extruder can be used to produce both floating fish feed and sinking fish feed. It is necessary to adjust the formula of fish feed for production. The output of the wet fish feed extruder is higher, and the wet fish feed extruder is equipped with a boiler, which can continuously supply hot steam to the screw during the fish feed production process, and the produced feed has higher maturity, smoother particles, and product quality. It is also better, and it is the first choice for large and medium-sized feed processing plants and farms. Wet fish feed extruders are also widely used in fish feed production lines.

Floating fish feed procesing machine
This is a floating fish feed making machine, its working principle is that the fish feed raw material enters the screw extrusion cavity, Under the action of extrusion, friction and shearing between the rod and screw sleeves, the internal pressure and temperature are continuously increased, and the starch in the fish feed raw material will be gelatinized. When the fish feed raw material comes out of the discharge port, its pressure is suddenly released in an instant, the water also evaporates a lot, the temperature also drops instantly, the fish feed raw material expands and condenses immediately, and there are many micropores in the condensed colloidal material, forming an extruded feed. The continuously extruded columnar or sheet puffed products also need to be cut by a rotary cutter and then cooled, and sometimes post-processing procedures such as drying and spraying additives (such as oils, vitamins, etc.) are required.
Influence of type of raw material on fishmeal physicochemical
2014/04/23 · Eleven feed mixes based on six independent FMs from herring (FMH) and five from sand eel (FMSE) were extruded according to standardized conditions. Type of fish raw material influenced FM physicochemical properties and had significant impact on starch gelatinization and pellet hardness.
Commercial Aquaculture Feed Production (Floating Feeds)
Extrusion Challenges Fiber content Nonreactive with starch or protein Absorbs water from other ingredients Solution: grind all ingredients well; change formulation Oil content Oil is a lubricant at high levels Screw can’t push dough
Pelleting Process - FAO
Pelleting Process (Extrusion) • Characteristics of feeds are produced by extruder • We can produce floating, sinking slow sinking feeds (remember feeding characteristics and habits of fish
=IF Extrusion - UMB
Physical properties of extruded fish feed The obtained ground fish feed premix after grinding had 95% of particles from 0.1 to 0.5 rnm. The RE of the experimental fish feed was positively influenced by PNHF and hence the density of the product (table 2). 56 Extrusion technology infeed and food processing
Feed Processing - an overview | ScienceDirect Topics
More commonly used in the twenty-first century for fish feed production is extrusion technology. Extrusion technology differs from pellet press technology in that it relies on plasticizing the ingredients through a combination of heat, shear, and compressional
Performance of aquafeed ingredients in extrusion cooking
2017/10/16 · In the extrusion process and in the presence of water, the starch granules first hydrate and swell. In the compression zone the starch swells even more and the protein starts to form a molten phase. As more energy is imparted, the granules soften and eventually rupture to form a
Performance Evaluation of Floating Fish Feed Extruder
The extrusion process operates in a dynamic steady equilibrium where input variables are balanced with the output. Hence to obtain the required output (extrudate), the
In food and fish feed extrusion processing, extruder operation merely depends on experience and "good luck". The frequently changed product recipes and raw materials often make the extruder operation out of control. In Thermo

Fishmeal physicochemical properties. Impact on the fish feed
Extrusion processing is a technology that enables production of such feed quality. Physical pellet quality is normally improved by the addition of starch and other binders, but recent research has shown that the protein ingredients in the feed mix also impact the physical quality of extruded feed products.
Basics of the Food Extrusion Process
The twin screw extruder is a continuous working process system which provides many basic process steps: coloring cooking melting flavor development evaporation pressurizing expanding What is
Optimization of single screw extrusion process for producing
2017/12/01 · Fish feed can be produced by pelleting or extrusion cooking. During extrusion cooking, raw ingredients undergo many chemical and structural changes, such as protein denaturation, starch gelatinization and formation of complexes between amylose and lipids ( González et al., 2013 ), which changes physical properties of products.
