Description
Technical field
The present invention relates to dietary fiber preparation field.More specifically, the invention relates to using for preparing sugarcane food fibre powder
Device.
Background technique
Sugarcane marrow is sugaring process or bagasse for the remainder after pulping and paper-making, is a kind of renewable biomass money
Source.Major part sugarcane marrow is intended only as after fuel combustion to recycle thermal energy at present, and utilization rate, surcharge are extremely low, very great Cheng
The waste of resource is caused on degree.
Dietary fiber is a kind of food with preferable health-care effect, has been more and more people to accept and has praised highly.It is selecting
When selecting dietary fiber, the water conservation oil absorbency of fiber is critically important considerations, prepares dietary fiber by raw material of bagasse
Method it has been reported that but how to improve sugarcane dietary fiber water conservation oil absorbency it is also not visible.
The equipment mostly produced in the prior art using screw-type extruder as fiber, screw-type extruder are revolved by screw rod
The pressure and shearing force for changing the line of production raw mix material uniformly, and existing screw-type extruder or extruder are mostly to be directed to
Food, field of fodder, sugarcane food fibre powder is because the physical property of itself is more special, with density is small, it is loose to meet, volume is big, flowing
Property it is bad the features such as, existing screw-type extruder, the feeding stage before material enters screw rod cavity, which is easy to appear, " puts up a bridge existing
As ", i.e. material is arranged at the top of addition vessel, and lower part does not have material, causes the phenomenon that empty shape occur during material movement.Separately
Outside, the fiber water conservation oil absorbency that general screw extruder obtains is poor, and expected value is also not achieved in the production for dietary fiber.
Summary of the invention
It is an object of the invention to solve at least the above problems, and provide the advantages of at least will be described later.
It is a still further object of the present invention to provide a kind of devices for being used to prepare sugarcane food fibre powder, can overcome object
There is " bridging phenomenon " in charging in material, and bagasse of the device based on sugarcane marrow is used to prepare sugarcane as raw material, by described
The device two-step pretreatment of food fibre powder, adjusts the variation of pressure and temperature, and the sugarcane diet for obtaining high water conservation oil absorbency is fine
Powder is tieed up, soluble dietary fibre content is higher in gained sugarcane food fibre powder.
In order to realize these purposes and other advantages according to the present invention, provides one kind and be used to prepare sugarcane dietary fiber
