Embodiment

[0043] Example 2 In the production of monosodium glutamate, the method and device of using a brush filter to purify concentrated corn steep liquor, the operation steps and structure can still refer to the attached figure 1 , but different from Example 1, wherein the liquid handling capacity of the brush filter 3 is 800m 3 / h, the heat exchange area of ​​evaporator 1 is 150m 2 .

[0044] Currently 500m 3 During the fermentation process, about 20 tons of concentrated corn steep liquor should be used, and after high-temperature sterilization at about 150°C at 0.13-0.16 MPa, the amount of sediment produced is about 5 tons. After utilizing the method and device of the present invention to purify concentrated corn steep liquor, the amount of precipitation is reduced to 0.5 tons. Most of the filter residue obtained after being filtered by a brush filter is protein, which can be added to corn bran to make feed to increase benefits. After accounting for 1,000 tons of corn steep liquor...

Abstract

The invention relates to a method and a device for purifying concentrated corn steel liquor through a brush filter in monosodium glutamate production. The method comprises the following steps: firstly, evaporating and concentrating corn soaking liquid in an evaporator, then filtering the corn soaking liquid in a filter cartridge of a brush filter, conveying filtered clear liquid to a corn steep liquor storage tank through a filter discharging valve for later use, and conveying protein flocculates and other impurities to the bottom of the brush filter after the protein flocculates and the other impurities are filtered; after the protein flocculates and other impurities at the bottom of the brush filter achieve a certain amount, opening a filter slag discharging valve to discharge the protein flocculates and the other impurities to a filter residue collecting tank. The process disclosed by the invention is simple and clear in route, simple in reconstruction, low in equipment investment, good in effect, automatic in slag discharge, and free from operator increase; protein and other organic impurities obtained from filtration can be used for manufacturing feed protein, so as to increase benefit; dirt formation in pipeline and equipment in subsequent fermentation and extraction processes is reduced, and pipeline conveying efficiency and equipment utilization rate are improved.

Description

technical field [0001] The invention relates to a technology for purifying concentrated corn steep liquor in monosodium glutamate starch technology, in particular to a method and device for purifying concentrated corn steep liquor by using a brush filter in monosodium glutamate production. technical background [0002] Concentrated corn steep liquor is an important raw material in glutamic acid fermentation medium. It is obtained by soaking corn with sulfurous acid and concentrating by evaporation. Its main nutrients are protein, glucose, various amino acids and trace elements. In addition, it also contains biotin, riboflavin and vitamin B1, which are necessary for biological activities. During the preparation process of concentrated corn steep liquor, through high temperature evaporation and concentration, part of the protein contained in corn steep liquor will be denatured, and at the same time the relative content of other impurities will increase, increasing the viscosi...
