Transport of material in a
single-screw press depends mainly on friction between the material
and the barrel's inner surface and the screw surface during screw
rotation. Thus, a solid core component, like seed hulls, is often
necessary to produce the fraction. This sometimes causes excess
frictional heat, large energy consumption and oil deterioration.
Furthermore, if single screw presses are not configured with
breaker bars or other special equipment, they provide inadequate
crushing and mixing.
Advantages of twin-screw press supplied by
China manufacturer
1,Our twin-screw press has the
higher transportation force, similar to a gear pump, and better
mixing and crushing at the twin-screw interface.
2,The oil expressed with twin-screw press had less foreign material
than the oil from the single-screw press. Other properties of the
oil were also good.
3, Energy consumption of the twin-screw press was more
efficient.
Work principle of twin-screw press supplied by China
manufacturer
Our twin-screw press extracts the
oil from oilseeds with high efficiency and produces a superior
quality oil and meal, especially for material that cannot be
expressed by single-screw presses without a force feeder, such as
dehulled sunflower seed. Using a twin-screw press also will omit
the usual pretreatments of cooking or flaking. The result is that
energy consumption for the overall process will be much lower than
single-screw processes. And the twin-screw pressing resulted in
less protein denaturation as compared to the single-screw press.
The twin-screw press has good crushing ability and, therefore, can
be used for oil expression from small seeds, such as rapeseed and
sesame seed.
