Description
Technical field
The present invention relates to utilize the technology of flour, Dregs Manufacture edible ethanol, belong to and utilize flour, Dregs Manufacture edible ethanol technical field.
Background technology
Bean vermicelli is in the history of the existing more than one thousand years of China, and is wherein famous with the Longkou bean vermicelli especially, is world known.Chinese bean vermicelli industry proportion in all industries is less, and technology, equipment develop relatively backward, but along with the reform exploitation, the not section improvement and perfect along with technology, equipment makes having developed rapidly of bean vermicelli industry.
The enterprise of domestic production bean vermicelli is broadly divided into three classifications with product: the one, and the beans Longkou bean vermicelli that five counties and cities districts such as local Zhaoyuan City, Yantai, Longkou City produce accounts for 70% of national bean vermicelli manufacturer.The 2nd, the potato vermicelli that area such as Qinhuangdao, Hebei, Sichuan Mianyang City produces accounts for 20% of national bean vermicelli producer.The 3rd, nationwide class does not sporadicly form output zone: with W-Gum, yam starch etc. is that the coarse cereal vermicelli of raw material production accounts for 10% of the whole nation.
Produce a large amount of saturated raw materials that do not absorb water in the production process of bean vermicelli, the bean vermicelli flour that separates later mung bean, pea waste residue and can't eat etc., these all are the byproducts that can't eat, present industry treating method is just directly taken out as animal-feed by simple processing, price is low, economic benefit is low, causes the waste of data, is unfavorable for the long term growth of company.
Summary of the invention
The objective of the invention is to solve the weak point that above-mentioned prior art exists, a kind of processing method of utilizing bean vermicelli flour, Dregs Manufacture edible ethanol is provided, this method can solve a large amount of flours that produce in the present bean vermicelli production industry, the waste problem of bean dregs, the a large amount of flours and the bean dregs that produce are recycled, realized that waste resource utilizes again, energy-conserving and environment-protective.
The present invention is achieved by the following technical solutions

Description of drawings
Fig. 1: the addition with waste residue is the cost curve figure of variable.
Embodiment
Below provide the specific embodiment of the present invention, be used for formation of the present invention is further specified.
Present embodiment is that flour, bean dregs and the waste water that contains starch are produced edible ethanol by the liquid alcohol fermentation technique, rich in starch by utilizing Workshop Production to discharge, albumen, fiber waste water are as batching water, bean dregs, flour silk are as main raw material, pre-treatment, saccharification, distiller's yeast by bean dregs and flour cultivated, ferments, distilled and produce edible ethanol, the wherein pre-treatment of bean dregs, flour, distiller's yeast are cultivated the emphasis research and development content for whole project, and the project gordian technique mainly comprises following content:
(1) proportioning of flour, bean dregs
The starch content of flour is about 80%, the starch content of bean dregs (doing) is about 40%, first, what solve is the blending ratio that flour is followed bean dregs, because bean dregs (doing) have 60% fiber, half fiber, being very easy to suction, is 1.8-2.2 according to the test ratio: the 1st, and only, just to join 1 weight part water content be the bean dregs of 85-95% to the flour of 1.8-2.2 weight part.
The present invention produces different with common edible ethanol, common edible ethanol is all produced by the grain conduct, and this is by utilizing non-grain raw material (bean dregs, flour silk) to produce, and the pretreatment technology of bean dregs, flour silk also is different fully, the edible ethanol impurity component that the present technique explained hereafter goes out is considerably less, content is very low, and quality is better.
