Though the technique for being used for farina processing above respectively has feature, not exclusively suitable for canna starch processing
With mainly：Canna starch particle is big, and its molecular weight is also very big, and fiber is big, pectic substance content is big, and starch precipitation is fast, uses
Cyclone easily produces blocking when carrying out refined, it is impossible to maintain the stable operation of whole system.
Utility model content
The purpose of this utility model is based on above-mentioned present situation and provides a kind of suitable for the refined of canna starch processing
Piece-rate system, canna starch particle can be smoothly solved greatly using the refining spearation system, and starch precipitation is fast in processing, easily blocks
Problem, and do not increase any system dynamic, it is ensured that the stability of Starch Production.
The purpose of this utility model is achieved through the following technical solutions：It is a kind of to divide suitable for the refined of starch processing
From system, including the Multi-stage spiral device being sequentially connected in series, mainly：The feed pipe of one-level cyclone is provided with one and is passed through after entering
The sub-material return duct and control valve of previous stage cyclone lower lumen.
The Multi-stage spiral device is divided into 8 grades, and being provided with one from the feed pipe of third level cyclone is passed through second level cyclone
The sub-material return duct and control valve of lower lumen, are provided with one and are passed through third level cyclone from the feed pipe of fourth stage cyclone
The sub-material return duct and control valve of lower lumen, by that analogy.The series of setting is reduced also dependent on needs are appropriate.
In the utility model, sub-material return duct enters cyclone inner chamber from cyclone bottom, and sub-material return duct is exported
To underflow outlet position.Sub-material return duct is 100-160mm away from cyclone bottom distance with the communicating position of cyclone.
The principles of science of the utility model institute foundation is：Canna starch breast under a certain pressure, is admitted to cyclone
Import.From at cyclone pipe import, the tangential direction along cyclone pipe enters inside cyclone pipe starch milk, the material each group in cyclone pipe
Divide and rotated by helix, and produce centrifugal force, when material goes downwards to tapered segment, due to the relative density of each component
（Proportion）Difference, granule size, shape are different and produce centrifugal force different, relatively denser component is mainly starch, obtains
Centrifugal force is larger, then moved along external spiral and thrown to cone inwall and drop to underflow opening along wall and discharge；And relative density is small
The centrifugal force that albumen and water are obtained is smaller, then when inside spin motion drops to close to cone bottom by underflow opening resistance and
The inside spin vortex for forming reverse rotational direction goes upward to top head piece discharge, so as to reach the purpose of each component separation.But work as
The starch of underflow flows not freely because particle is big, concentration is high, will form blocking, causes system operation unstable.In every one-level
Install a return duct on the feed pipe of cyclone additional.Sub-material backflow pipe diameter is not more than 1/3rd of feed pipe, and is provided with
Flow control valve.Partial starch breast is backed into previous stage cyclone inner chamber, and underflow outlet position is pointed in return duct outlet,
Reduce the inlet amount of feed pipe.The starch milk pressure for backing into the underflow of previous stage cyclone is higher, adds previous stage original
Underflow, flow be increased, and pressure is also improved, and make the mobility of underflow more preferably, therefore would not produce blocking.By eddy flow
After device pump, flow and pressure into next stage cyclone all increased, after reaching dynamic equilibrium, whole hydrocyclone system
Blockage problem is eliminated, into benign steady operational status.The cyclones at different levels of the refined cyclone of canna starch are all successively
Solve blockage problem.Whole process, operation is smooth, and product quality is protected, and yield can also keep stable yields.
It is of the present utility model to have the prominent advantages that：After installing sub-material return duct additional, the mobility of cyclone underflow is may be such that more
It is good, blocking will not be produced, and do not increase any power of system, it is particularly suitable for continuously extracting the processing work of canna starch
Skill, can smoothly solve that canna starch particle is big, starch precipitation is fast in processing, the problems such as easily block, it is ensured that the company of Starch Production
Continuous property and stability.

Specific embodiment
The utility model is described further below in conjunction with accompanying drawing with regard to its structure：
As shown in Figure 2：A kind of refining spearation system suitable for starch processing, including the Multi-stage spiral device 2 being sequentially connected in series,
Wherein：The feed pipe 1 of one-level cyclone is provided with a sub-material return duct 4 for being passed through previous stage cyclone lower lumen after entering
With control valve 5.The Multi-stage spiral device is divided into 8 grades, and being provided with one from the feed pipe 1 of third level cyclone is passed through second level eddy flow
The sub-material return duct 4 and control valve 5 of device lower lumen, are provided with one and are passed through third level rotation from the feed pipe of fourth stage cyclone
The sub-material return duct 4 and control valve 5 of device lower lumen are flowed, by that analogy.
Sub-material return duct enters cyclone inner chamber from cyclone bottom, and underflow outlet position is pointed in the outlet of sub-material return duct
Put.Sub-material return duct 4 is 100-160mm away from cyclone bottom distance with the communicating position of cyclone 2.
The course of work of the present utility model is as follows：
Referring to Fig. 2：Stream（I.e. canna starch is newborn）The import of cyclone 2 is sent into by delivery pump 3.Starch milk is from cyclone pipe
At import, the tangential direction along cyclone pipe enters inside cyclone pipe, and material each component presses helix and makees to rotate fortune in cyclone pipe
It is dynamic, and centrifugal force is produced, when material goes downwards to tapered segment, due to the relative density of each component（Proportion）Different, granularity is big
Small, shape is different and produce centrifugal force different, relatively denser component is mainly starch, and it is larger to obtain centrifugal force, then along outer
Screw is thrown to cone inwall and drops to underflow opening along wall and discharge；And the small albumen of relative density and water obtain centrifugal force
It is smaller, then the interior spiral shell of reverse rotational direction is formed by the resistance of underflow opening when inside spin motion drops to close to cone bottom
Bumpy flow goes upward to top head piece discharge, so as to reach the purpose of each component separation.Installed additional in the feed pipe 1 of every one-level cyclone
A piece sub-material return duct 4, sub-material backflow pipe diameter is not more than 1/3rd of feed pipe, and is provided with flow control valve 5.Will
Partial starch breast backs into previous stage cyclone inner chamber, and underflow outlet position is pointed in return duct outlet, reduces entering for feed pipe
Doses.The starch milk pressure for backing into the underflow of previous stage cyclone is higher, adds the original underflow of previous stage, and flow increases
, pressure also improves, and makes the mobility of underflow more preferably, therefore would not produce blocking.After by cyclone pump, under
The flow and pressure of one-level cyclone all increased, and after reaching dynamic equilibrium, whole hydrocyclone system is eliminated blocking and asks
Topic, into benign steady operational status.The cyclones at different levels of the refined cyclone of canna starch all solve blockage problem successively.
Whole process, operation is smooth, and product quality is protected, and yield can also keep stable yields.
