Example Embodiment

[0033] Example 1

[0034] A kind of recycling processing method of potato starch processing waste provided by the present embodiment, it comprises the following steps:

[0035] First, 21L of the first potato starch processing wastewater was added to a fermentor with a capacity of 30L, and the temperature in the fermenter was controlled to be 27.5°C, and the first fermentation was performed, and the fermentation time was 24 hours. In addition, from the beginning of the first fermentation, the oxygen capacity of the fermentation liquid in the fermenter is always maintained at more than 30%. Specifically, it is controlled by adjusting the air delivery flow of the oxygen delivery pipeline in the fermenter.

[0036] Secondly, in the first fermentation process, the second potato starch processing wastewater is treated with saccharification yeast and sterilized, and after the first fermentation is completed, the sterilized second potato starch processing wastewater It is added to th...

Abstract

The invention discloses a recovery processing method and technology of a potato starch processing waste material, and relates to the field of starch processing. The recovery processing method of the potato starch processing waste material comprises the following steps: removing starch in the potato starch processing waste material by using a fermentation technology to extract soluble protein therein, specifically decomposing and converting the starch into glucose through a starch enzyme generated by metabolism of saccharomycetes, and then using the glucose to carry out aerobic respiration; finally using up the starch or the converted glucose by the saccharomycetes, wherein remaining soluble protein and cellulose are recovery processing products of the potato starch processing waste material. According to the recovery processing technology comprising the recovery processing method of the potato starch processing waste material, the pollution of the potato starch processing waste material on the environment can be reduced, and the utilization rate of material resources can be improved.

Description

technical field [0001] The invention relates to the field of starch processing, in particular to a method and process for recycling and processing potato starch processing waste. Background technique [0002] my country's potato starch processing industry has developed rapidly in recent years. According to surveys, there are currently more than 2,000 starch production enterprises in the country, and the annual processing capacity of potatoes is as high as more than 8 million tons, of which the annual processing capacity of potato starch is more than 1.2 million tons. There are three main products in the potato starch production process: the main product is potato starch, and the by-products are potato residue and production wastewater. Among them, the treatment process of potato residue is very simple and not easy to cause pollution. Since potato starch wastewater contains a large amount of organic compounds, such as protein and sugar, it also contains some starch granules, ...
