Preparation equipment, preparation method and application of thallus compound amino acid feed additive

Abstract

The invention provides preparation equipment, a preparation method and an application of a thallus compound amino acid feed additive. The preparation equipment of the thallus compound amino acid feed additive comprises a material crushing device, a hydrolysis reaction device, a solid-liquid separation device, a filtrate collecting device, an impurity removing device, an inorganic ion removing device, a compound amino acid solution collecting device and a drying device which are sequentially connected by virtue of a conveying device. The preparation method of the thallus compound amino acid feed additive comprises the following steps: crushing microorganism residues and then hydrolyzing, carrying out solid-liquid separation on hydrolysis reactants, and collecting filtrate; removing impurities and inorganic ions from the filtrate, so as to obtain the compound amino acid solution; and drying the obtained compound amino acid solution, so as to obtain the thallus compound amino acid feed additive. The thallus compound amino acid feed additive is applied to animal feeding. By adopting the preparation equipment, the preparation method and the application of the thallus compound amino acid feed additive, the problem of treating the microorganism residues is solved, waste is recycled, the obtained feed additive has high amino acid content, is reasonable in ratio of necessary amino acids and easy to absorb and can well promote growth and development of animals.

Description

technical field [0001] The invention belongs to the technical field of feed additive preparation, and in particular relates to a device and a method for preparing bacterial compound amino acid feed additive by using microbial residues, and the application of the feed additive. Background technique [0002] With the development of biological fermentation industries such as monosodium glutamate, citric acid, enzyme preparations, beer, and alcohol in China, a large amount of yeast fermentation waste liquid is produced every year, and its bacterial content is high. For example, the residual glutamic acid in glutamic acid fermentation waste liquid is about It is 1.2% to 1.5%, high in COD, high in ammoniacal nitrogen, and generally low in pH. It is a kind of industrial wastewater that is very difficult to treat. [0003] With the intensification of eutrophication in water bodies, algae in water bodies, such as blue-green algae and green algae, are flooding many water areas, threat...

AI Technical Summary

Problems solved by technology

At present, the common treatment method is to collect the algae and then crush, squeeze and landfill, and a small part is crushed to make feed or fertilizer, but the treatment cost is very high, and long-term application will result in the introduction of a large number of exogenous microorganisms and minerals. Soil compaction and other issues

[0004] With the development of urban construction, the output of surplus sludge in urban sewage plants has increased year by year. A large amount of sludge has not been harmlessly treated, that is, it is discharged and piled up randomly, causing serious pollution to the surrounding environment and great harm to human health.
