Extruded feed processing is a new feed processing technology, the material in the twin-screw extruder
cavity temperature instantaneous puffed actually a process: a mixture of high temperature (110 -200 ℃),
high pressure (25-lOOkg / cm2 ), and high shear, high moisture (10% -20% or even 30%) of the environ
ment, by continuous mixing, conditioning, heating pressurized ripening, after the formation of an expans
ion extrusion die orifice and suddenly buck loose porous feed. The following analysis of the advantages
of extruded feed:

1 Improving feed utilization

2 Reducing environmental pollution

3 Reducing the occurrence of disease

4 Improving the breeding density

5 Extending the storage period Feed

6 Easy feeding management

7 Can meet the different needs of animals feeding habits

Extruded feed, depending on process can be divided into buoyancy slowly settling, quickly settling 3 types.
Currently, about 80% of the fish feed fodder for the settlement, such as shrimp, salmon, salmon, yellow tail
tuna feed like settlement, while catfish, tilapia, eel, most fish larvae are like floating feed , catfish, tilapia feed
equal preference for settlement and floating feed. Furthermore, extruded feed but also to meet some special
requirements, such as low moisture feed, high-fiber feed.
