Problems solved by technology

[0013] However, there is no systematic and complete industrial process for the production of crystalline glucose in the prior art. In addition, the DX purity of the crystallized material is generally about 96% after purification, and it must be crystallized more than twice, resulting in a large amount of mother liquor and poor crystal quality. , low yield

Embodiment 1

[0070] Based on the theoretical production of 1000kg anhydrous glucose finished product:

[0071] Raw material consumption is:

[0072]

[0073]

[0074] Production process:.

[0075] 1. Transformation section

[0076] (1) Formula milk

[0077] Pour the dry starch in the bag into the milk blending tank for milk blending, and enter the pre-preparation tank after filtering.

[0078] (2) Pre-modulation

[0079] In the pre-conditioning tank, adjust the pH value of the starch milk to 5.8-6.2 with 10% sodium carbonate solution, then add high-temperature-resistant α-amylase, and simultaneously add 10% calcium chloride solution 50-100ppm (as the enzyme's activator).

[0080] 2. Liquefaction and saccharification section

[0081] Use a pump to inject the adjusted starch milk into the primary steam injector, so that the temperature of the material rises to 105 ° C ~ 108 ° C instantly, and the material is kept in the pressure tank for 3 ~ 5 minutes, and the pressure in this ar...

Abstract

The invention discloses a preparation process of anhydrous dextrose. The preparation process comprises six work sections, i.e., a reforming section, a liquefying section, a saccharifying section, a refining section, a chromatographic separation section and an evaporative crystallization section; the industrial preparation process of the anhydrous dextrose is systematically and completely disclosed; the process parameters of the traditional reformation, liquefaction, saccharification and refining sections are adjusted, the chromatographic separation section is added before evaporative crystallization, and the dextrose is produced by adopting a chromatography process, so that not only are the problems of low yield, long production cycle and efflux of mother liquor of crystalline dextrose solved, but simplification of the crystallization process and increment of economic value are also realized.

Description

technical field [0001] The invention relates to the technical field of glucose production, in particular to a process for preparing anhydrous glucose. Background technique [0002] Crystalline Anhydrous Glucose [0003] Chinese name: Dextrose Anhydrous [0004] Chemical name: α-D-hexacyclic glucose [0005] English name: Anhydrous Dextrose [0006] Chemical Structure: [0007] [0008] product description [0009] Physical and chemical properties: Anhydrous glucose is colorless or white, shiny crystalline powder. Odorless, sweet, soluble in water. The specific rotation is +52.5-53.0°, the melting point is 146°C, and it is easy to absorb water and transform into hydrous crystals, and it can absorb water and transform into hydrous α-glucose in about 30-60 minutes. If there are a small amount of very fine hydrous crystals attached to the surface of anhydrous α-glucose crystals, the speed of absorbing water is faster, and it can be completed in about 1-8 minutes.
