Problems solved by technology

[0003] The purpose of the present invention is to provide a preparation method of amino acid-containing water-soluble powder fertilizer. The first purpose is to use the principle that anhydrous magnesium sulfate is easy to absorb free water in the solution at room temperature, and lock the free water, thereby realizing The purpose of non-heating evaporation and solidification of liquid amino acid chelated fertilizers; the second purpose is to solve the problem that the mixed amino acid mother liquor produced in the amino acid production process is difficult to handle and easily causes environmental pollution

Embodiment 1

[0026] 1. Collection and treatment of mother liquor containing mixed amino acids: Take 1000kg of protein hydrolyzate (about 1m 3 ), injected into the decolorization storage container, the content of the mixed amino acid in the mother liquor obtained was analyzed and detected to be about 15%, and 1 kg of activated carbon was added to the decolorization storage container for decolorization. The decolorization reaction time was 40 minutes, and the mother liquor was decolorized with liquid ammonia The pH of the solution was adjusted to 4.5, and then the active carbon and insoluble impurities were filtered out with a plate frame to obtain the decolorized mother liquor.

[0027] 2. Chelating reaction between the decolorized amino acid mother liquor and trace elements: according to the amino acid content in the mother liquor, add one or more of zinc sulfate, ferrous sulfate, magnesium sulfate, manganese sulfate, and boric acid to the amino acid mother liquor after decolorization One ...

Embodiment 2

[0032]1. Collection and treatment of mother liquor containing mixed amino acids: take the protein hydrolyzate after the production of amino acids and separate L-cystine, L-tyrosine, L-leucine, L-arginine, L-histamine 1000kg (about 1m3) of the mixed solution after extracting monomeric amino acids from one or more acids in the acid is injected into the decolorization storage container. After analysis and detection, it is found that the content of the mixed amino acid in the mother liquor is about 10%. In the decolorization storage container Add 1 kg of activated carbon to the solution for decolorization, the decolorization reaction time is 40 minutes, and the pH of the mother liquor is adjusted to 6.5 with concentrated hydrochloric acid with a concentration of 30% by mass percentage at the same time, and then the activated carbon and insoluble impurities are filtered out with a plate frame to obtain the decolorized mother liquor.

[0038] 1. Collection and treatment of mother liquor containing mixed amino acids: take the protein hydrolyzate after the production of amino acids and separate L-cystine, L-tyrosine, L-leucine, L-arginine, L-histamine 1000kg (about 1m3) of the mixed solution after extracting monomeric amino acids from one or more acids in the acid is injected into the decolorization storage container. After analysis and detection, it is found that the content of the mixed amino acid in the mother liquor is about 10%. In the decolorization storage container Add 1 kg of activated carbon to the solution for decolorization. The decolorization reaction time is 40 minutes. At the same time, the pH of the mother liquor is adjusted to 8.0 with liquid ammonia, and then the activated carbon and insoluble impurities are filtered out with a plate frame to obtain the mother liquor after decolorization.

Abstract

The invention provides a preparation method of a water-soluble powdery fertilizer containing amino acid. The preparation method is performed according to the following steps: 1, collecting and treating mother liquid containing mixed amino acid; 2, performing a chelation reaction on decolored amino acid mother liquid and trace elements; 3, concentrating liquid amino acid chelated liquid; 4, solidifying and crystallizing a liquid strong amino acid chelate fertilizer; and 5, packaging the solidified and crystallized liquid strong amino acid chelate fertilizer. The water-soluble powdery fertilizer containing the amino acid, disclosed by the invention, is simple in production technology and high in controllability; in a production process, the autologous water absorption and water solidification characteristics of anhydrous magnesium sulphate are used for replacing a traditional spray drying technology, and environment is not polluted.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a method for preparing amino acid-containing water-soluble powdered fertilizers. Background technique [0002] Amino acid is the basic unit of protein. As the first nutrient element in the body, protein plays an obvious role in food nutrition. However, it cannot be directly used in the human body, but is converted into small molecules of amino acids. Take advantage of. In addition, amino acids have significant effects in regulating the balance of body functions, promoting nutrient absorption, delaying aging, and beautifying the skin. With the improvement of people's living standards, people pay more and more attention to their own health and food safety. Amino acids are accepted and taken by more and more people because of their remarkable efficacy. Therefore, the market demand for amino acids has shown a double-digit growth in the past 10 years. The market demand has greatly stimul...
