Extrusion processing technology has become of major importance in the production of modern feeds used in intensive aquaculture. In recent years there has been a constant growth in the application of extruded diets for aquatic feeding. Aquatic feed by extrusion have superior water stability, better floating property and a higher energy than pelleted diets, which contributes to the increase in fish growth and improvement in feed conversion. Therefore compared with the conventional pelleting process, extrusion technology is the most efficient way to improve the performance of aquatic feed.

Extruder and Expander

Extruder and expander are fish feed machines that mainly apply extrusion and expansion technology in feed pellet production. fish feed machine is a bio-reactor providing the necessary pressure to force feed mash in the barrel through a restrictive die. Through changes in temperature, pressure, and shear within the barrel, the raw material is forcibly homogenized before it assumes the cross-sectional shape of the die opening. Extrusion equipment is mainly composed of power transmission device, feeding device, pre-conditioner, floating fish feed machinebarrel and discharging cutting device, etc. The barrel of extruder is composed of barrel heads, screw auger, flow restrictors (called shearlocks) and a cross-sectional die.

Expanders are similar to extruders, but they have difference in treatment effects and applications. Expanders are commonly used as mechanical conditioners for treating materials which are difficult to pellet, to increase the digestibility of cellulose and protein components in order to perform feed hygienistion. Extruders consist of barrels with one or two screws to transport materials and force them through a die. Extrusion can be considered as a high shear treatment. The shear action during expander treatment is much less. Compared to an extruder, the simplicity of the expander allows an effective treatment of relatively large quantity of feed at a low cost. floating fish feed machine has received the dominating role production of fish feed. For extruder, there are different types available in the market, such as single screw extruders, twin screw extruders, wet fish feed machine, dry fish feed machine and etc.

Dry Type and Wet Type Fish Feed Machine

Dry type floating fish feed machine is the type of machine that does not require a steam boiler for heat or steam injection or jacket heating, and all product heating is accomplished by mechanical friction force. Without utilizing preconditioning, dry extrusion employs lower moisture levels. Therefore it is suitable for processing low moisture and high fat feed material.
While wet type floating fish feed machine is a piece of more complex equipment with precision metering systems for steam or water injection into the conditioner and/or the extruder barrel. Preconditioning is a very important step in wet extrusion process for chemical or physical reactions to take place. The heart of the floating fish feed machine working is: preconditioning, cooking and die shaping. High temperature and high pressure process can kill the salmonellosis and bacterial infections and also makes the pellets easily to digest.

Advantages of Extruded Aqua-feed Pellet

1.Wide adaptability
The capability of an extruder enhances the feed manufacturer’s flexibility to produce fish feed pellets for shrimp, crab, eel, catfish, carp, frogs and etc..
2.High starch gelatinization
Feed material goes through the processing of HTST, starch gelatinization degree increase can reach 80-99% for aquatic animals easily digest.
3.Better digestion and absorption
Pellets can breakdown quickly in the stomach of fish loses nutrients (during regurgitation), which contributes to better absorb nutrients.
4.Improved water stability
The floating pellets are more resistant to disintegration in water and a floating feed allows the fish farmer to observe the condition of the fish and the amount of feed consumed.
5. Water absorption
Extrusion moisture content during processing can be controlled over a wide range, which helps to increase the water stability of the final feed. These pellets absorb more water, retains shapes for longer time and results in reduced losses of nutrients. It benefits pellet technical qualities and fish health.
6.Convenient for density control
It is entirely feasible for an extruder to produce floating feed, sinking feed and slow sinking feed by density control; that is more conducive to different fish species.
