Problems solved by technology

Most of the production of pentosan in the prior art is to use the by-products of wheat, such as bran, wheat starch, etc., and the by-product light phase liquid produced by the production of wheat starch is not well utilized, resulting in waste and increased processing costs. More or less chemical substances are added in the production process, and there are still problems such as insufficient utilization of raw materials

Embodiment 1

[0013] A production and processing technology of wheat flour and the light phase substance of wheat flour - pentosan. The production and processing steps are as follows: ① take wheat flour or wheat flour as raw material, add water and make dough slurry; Carry out centrifugation to obtain light phase substances, wheat starch, gluten; ③Use a decanter, disc or tubular centrifuge to separate the light phase substances through membrane filtration with a separation factor of 5000-20000, and then use a vibrating screen for further separation. Filter to separate large particles and impurities; ④ Preheat the light phase material with a plate heat exchanger or spiral plate, then enter the conical pot, steam cook at a temperature of 50°C-200°C, and then use vibration Sieve for re-filtering; ⑤ Precipitate the filtered liquid to remove protein, starch, crude fiber and bran in the upper and lower layers to obtain a solution; Separation of the solution under certain conditions; ⑦The separate...

Abstract

The invention discloses a production and processing technology of a light phase substance pentosan of wheatmeal and wheat flour. The production and processing technology comprises the following steps: carrying out centrifugal separation on a light phase substance of a raw material, steaming, precipitating and filtering a product, concentrating, adding amylase and extracting, and finally carrying out drying treatment. The whole process of the production technology has high degree of automation. The by-product the light phase substance produced after production of wheat starch is fully utilized, thus changing waste into valuables. The raw material is fully utilized. Comprehensive utilization rate of the product is high. By pipeline production, there is no pollution during the whole course. There is no addition of chemical substances during the production process. Thus, there is no pollution and it is beneficial to environmental protection. The period of the production process is short, and added value of the product is high.

Description

technical field [0001] The invention relates to a production and processing technology of pentosan, in particular to a production and processing technology of pentosan, a light phase substance of wheat flour and wheat flour, and belongs to the field of polysaccharide processing. Background technique [0002] Pentosan is a non-starch polysaccharide, in addition to a large amount of pentose polymers, it may also contain a certain amount of hexose, phenolic substances and heteropolysaccharides. Pentosan is widely found in cereals (such as wheat, rye, sorghum, etc.), but the content is very small. It is an important component of plant cell walls; 60%-70% of the extracellular parenchyma of the aleurone layer and the extracellular parenchyma of the endosperm layer of most cereals is composed of pentosan. Pentosan plays an extremely important role in maintaining plant life. For the method of producing pentosan from wheat by-products, in ZL201210085686.X "A Method for Extracting P...
