Embodiment Construction

[0027] The technical solution of the present invention and its beneficial effects will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 The table above shows the composition of corn soaking water. From the table, it can be seen that the corn soaking water contains organic substances such as protein, lactic acid, and phytic acid. If such organic components can be extracted and utilized, it will turn waste into treasure, and realize resource utilization. The dual benefits of utilization and environmental protection.

[0029] For example, the processed protein products extracted from corn soaking water are fully soluble, easy to absorb, rich in amino acids, etc., which can improve the absorption and utilization rate of animals and achieve rapid growth; phytic acid can be processed into calcium phytate for the production of biopharmaceuticals A good raw material for inositol; lactic acid can be processed into calcium lactate comp...

Abstract

The invention relates to the technical field of corn deep processing, particularly to a corn soaking water resource treatment method, which comprises: taking corn soaking water as a raw material; separating out solid insoluble substances and small-particle substances, and filtering and separating out solid substances by a filter press; carrying out anion-cation resin exchange extraction to obtainphytic acid, and further producing calcium phytate; feeding the corn soaking water subjected to resin exchange treatment enter a microfiltration-ultrafiltration-nanofiltration membrane separation system, extracting the concentrated water, and concentrating and drying the soluble proteins in the soaking water to prepare protein powder; and concentrating the clear water subjected to nanofiltration treatment by using a high-pressure reverse osmosis membrane, feeding the concentrated water into a neutralizing tank, adding quick lime, carrying out stirring neutralizing, carrying out filter pressingdehydration, and drying into powder or blocks to obtain the calcium lactate compound. According to the scheme, the raw material source is the remaining soaking wastewater of the corn deep processingproject, so that the raw material cost is low, only the extraction and production operation cost is needed, the industrialization is achieved, the waste is turned into wealth, and the dual benefits ofresource utilization and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of corn deep processing, in particular to a method for resourceful treatment of corn soaking water. Background technique [0002] During the production process of corn deep processing, corn soaking wastewater is generated every day. At present, the traditional method of evaporating and concentrating is sprayed into white skin fiber and germ meal for sale, which has low economic benefits and cannot fully reflect the actual value of corn soaking water. Because corn steep liquor contains mycotoxins, it affects the quality of fiber feed. With the enforcement of feed standards, large feed companies will strictly control the content of mycotoxins in sprayed fiber feed. [0003] The protein content in corn soaking water is about 3%, and the phytic acid content is 0.8%; among them, phytic acid can extract inositol with higher added value; protein in corn soaking water can be used to prepare protein feed, and the a...
