The invention discloses improved starch secondary liquefaction maintaining apparatus in the crystalline glucose production, and belongs to the field of glucose production. The apparatus comprises a liquefier body, maintaining pipelines, conveying packing augers, heat preservation layers and electromagnetic valves, wherein a primary liquefied liquid joint is arranged at the upper part of the liquefier body, the plurality of maintaining pipelines are uniformly distributed below the liquefier body from top to bottom, a rotating shaft is mounted in each maintaining pipeline, a motor is mounted atone end of each rotating shaft, a heating wire is mounted on the outer side of each maintaining pipeline, and a temperature sensor is mounted at the upper part of each maintaining pipeline. The apparatus has the following beneficial effects: through the cooperative use of the motors, the rotating shafts and the conveying packing augers, a liquefied liquid can be conveyed from one end of each maintaining pipeline to the other end of the maintaining pipeline, the liquefied liquid with certain viscosity can be prevented from adhering to the inner walls of the maintaining pipelines, and the conveying of the liquefied liquid in the maintaining pipelines at a constant speed can be ensured.

Description

technical field [0001] The invention belongs to the field of glucose production, in particular to an improved starch secondary liquefaction maintenance device in crystalline glucose production. Background technique [0002] Glucose is an essential nutrient for metabolism in organisms. The heat generated by glucose oxidation is an important source of energy required for life activities in the human body. Edible corn starch is a raw material for glucose production, which is produced under the action of starch glucoamylase. The process of producing glucose from starch requires liquefaction, that is, under the action of alpha amylase, the starch is transformed from a high molecular state to a lower molecular state, and at the same time, the viscosity of the starch is reduced, and the starch is transformed from a semi-solid state to a solution state. When starch milk is used to produce crystalline glucose, two injection liquefaction processes are currently used. The second inject...

AI Technical Summary

Problems solved by technology

When using starch milk to produce crystallized glucose, two injection liquefaction processes are currently used. The second injection liquefaction is generally carried out in a pipeline with a length of 35 meters. However, most of the existing secondary injection liquefaction pipelines have a single structure and it is difficult to maintain balance. The temperature of the liquefied liquid is gradually lost during the process of transporting the liquefied liquid in the pipeline, resulting in different temperatures before and after the pipeline, and the liquefied liquid is heated unevenly. At the same time, the liquefied liquid still has a certain viscosity and is easy to stick to the inner wall of the pipe.
