Method for removing impurities from sorgo

Abstract

The invention provides a method for removing impurities from sorgo. The method comprises the following steps of: cutting: cutting sorgo straws into 10-30cm; dry-cleaning: conveying the cut material into a disperser for dispersing and extracting at negative pressure at the same time; water-cleaning: conveying the dried-cleaned material by a link plate, wherein the dried-cleaned material is sprayed and rinsed 3-4 times according to the water volume of 0.05-0.3t in each ton of straws; squeezing: squeezing the rinsed material to produce mixed sugar juice; and flocculating: adding a flocculating agent to the mixed sugar juice for carrying out flocculating reaction, and feeding the flocculated supernatant juice into a subsequent working section. The method disclosed by the invention realizes removal of the impurities in the sorgo straws with a simple and efficient method, is beneficial to reducing the influence on the subsequence process, has a simple process and greatly-reduced operation cost and ensures that relative loss of sugars in the materials is little.

Description

technical field [0001] The invention relates to a sweet sorghum impurity removal method, in particular to a simple and efficient sweet sorghum impurity removal method with little sugar loss. Background technique [0002] As a non-grain crop, sweet sorghum stalks can be used as raw materials for the production of fuel ethanol, opening up a new path for the development of clean energy; however, sediment will inevitably be introduced during harvesting and transportation, which will bring great impact to subsequent production. Difficulties, such as: (1) a large amount of sediment and serious equipment loss; (2) a large amount of sediment will cause pipeline blockage and affect subsequent production. At the same time, the sugar content in the leaves and sheaths of sweet sorghum is low, the extraction value is small, and the equipment loss is large during pressing. Therefore, it is of great practical significance to find an economical, simple, efficient and less sugar loss treatm...

AI Technical Summary

Problems solved by technology

[0005] In order to improve the problem of low impurity removal rate and high sugar loss in the prior art, especially the problem of excessive energy consumption, the present invention effectively utilizes pretreatment, such as initial sand removal by oscillation, and subsequent negative pressure absorption after cutting Such methods effectively remove the impurities of sweet sorghum stalks while ensuring the minimum loss of sugar, and greatly save energy consumption
