Abstract
The invention discloses a coarse starch recovery treatment method, which comprises the following steps: step I, starch serum whey is dehydrated to become solid wet starch, the wet starch enters a first conveyor mechanism, and is stirred and pushed to move in the first conveyor mechanism, and conveyed to a drying system for drying so as to obtain dry starch, and coarse starch and fine starch are obtained by processing the dry starch with a powder screening machine and separating; step II, the separated coarse starch is conveyed to the first conveyor mechanism through a second conveyor mechanism, and the coarse starch and the wet starch entering the first conveyor mechanism are stirred and mixed by the first conveyor mechanism and then are conveyed to the drying system for drying, and coarse starch and fine starch are obtained by processing the dried dry starch with the powder screening machine and separating; step III, the step II is repeated. By adopting the coarse starch recovery treatment method, the separated coarse powder is reused, less powder heads are generated, meanwhile, the drying efficiency is improved, the cost is redcued, and the energy consumption is reduced.
Description
Technical field
The present invention relates to starch production field, particularly a kind of meal recovery and treatment method and meal recovery and processing system.
Background technology
At present, in the production process of converted starch, the meal of being separated by sieving machine is generally by Fan pipeline, to be mixed after dissolving by sieving machine circular treatment or hydrolysis in dried starch again and mixed in starch serum and again process after entering flour mill and pulverizing.In current this production process, this processing mode cost is too high, meal is commonly called as prostitute, after its source is mainly the dehydration of converted starch serum, wet starch presents certain bulk, although through stirring fragmentation, but because humidity is too large, or can not be rendered as powdery completely, lump starch is after air-flow hot-air seasoning, what have is separated into powdery, what have forms compared with coarse granule shape, when sieving machine, cannot form prostitute by wire screen, in sieving machine processing procedure, also having part fine powder to be accompanied by more coarse grained powder discharges, formed prostitute, wet starch caking is more, prostitute is just more, the energy consumption of processing prostitute is just larger.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of meal recovery and treatment method and meal recovery and processing system, by this processing method and treatment system, the meal that sieving machine is separated is recycled, both reduced prostitute's generation, also improved drying efficiency, saved cost, reduced energy consumption simultaneously.
Technical scheme provided by the invention is:
A meal recovery and treatment method, comprises the following steps:
