2 General description

2.1 Application and adaptability

MY265 Single-Screw Extruder developed by FAMSUN Co., Ltd (hereafter referred to as
"extruder") is mainly used for processing floating and sinking feed in aquafeed industry
As for a pioneer application in new fields, please consult FAMSUN experts for further
technology support.

2.2 Main components and working principle

2.2.1 Main components

The mechanical equipment of extruder system is mainly composed of feeding bin, feeder,
conditioner, principle machine, and pipeline systemetc. See Fig. 2-1. There is electric control unit
besides the mechanical equipment.
1. Feeding bin

2.2.2 Working process

First of all, the materials prepared, blended and pulverized enter the feeding bin with
bridge-breaking device for further process. Then the materials in bridge-breaking feeding bin are
delivered by the feeder to the double-shaft differential-speed conditioner (DDC) for conditioning
where mixed with injected steady, continuous and metered steam, water, and other liquids.
The materials being conditioned for a certain period of time enter feeding section of the extruder
assembly for being conveyed from the feeding section, mainly used to convey and primarily
compress the materials, to kneading section; in the kneading section, materials will be gradually
cured or dissolved through strong stirring, mixing and shearing; meanwhile pressure and temperature
will further rise at the final curing section. As a result, the materials will be cured more; starch will be
gelatinized further; fat and protein will be denaturalized; and thereafter all get homogenized to form a
non-crystal texture. Finally, such materials will be extruded out and cut into shapes through the
discharging assembly.
