preparation example Construction

[0068] A kind of preparation method of amino acid fertilizer water slurry special for aquaculture, its steps are:

[0069] A. Production of amino acid solution (see attached figure 1 )

[0070] a. Hydrolysis ①

[0071] Hair (any one of human hair, pig hair, chicken feather, duck feather, goose feather, wool, cow hair): hydrochloric acid (28-31%) = 1:2, the temperature is controlled at 108 or 110 or 111 or 113 or 114 or 115 ℃, reaction time 6 or 7 or 8h;

[0072] b. Neutralization②

[0073] Neutralize to pH 4.8 or 4.9 or 5 or 5.1 with 99.9% liquid ammonia 40 or 43 or 46 or 48 or 51 or 55 or 58 or 61 or 64 or 66 or 68 or 70°C;

[0074] c. Filtration (including crude ③ and refined ④)

[0075] The filter cake extracts L-cystine, L-leucine, and L-tyrosine, and the filtrate is transferred to the concentration process for subsequent use;

[0076] d. Concentration⑤

[0077] Concentrate the filtrate to 28 or 29 or 30Be' at -0.06 or -0.07 or -0.08Mpa to obtain amino acid solution...

Abstract

The invention discloses amino acid fertilizer water slurry special for aquaculture and a preparation method of the amino acid fertilizer water slurry. The amino acid fertilizer water slurry consists of amino acid solution, microelements, fermentation organic matters, inorganic fertilizer, mineral matters, a water quality modifier and beneficial bacteria according to a certain proportion. The preparation method comprises the following steps of: A, producing the amino acid solution, i.e., a, hydrolyzing, b, neutralizing, c, filtering and d, concentrating; B, producing the fermentation organic matters, i.e., a, stirring, uniformly stirring organic matter raw materials with the amino acid solution, b, inoculating, uniformly stirring the organic matter raw materials with the beneficial bacteria, and c, fermenting; and C, producing the amino acid fertilizer water slurry, i.e., a, chelating, heating the amino acid solution, and adding the microelements under stirring for chelating, b, mixing, adding the fermentation organic matters, the inorganic fertilizer, the mineral matters, the water quality modifier and the beneficial bacteria in sequence and uniformly stirring and mixing, c, checking according to related quality standard, and d, packaging. According to the amino acid fertilizer water slurry, the immunity of fishes is improved, diseases are reduced, the breeding yield of spotted sliver carp is increased, the fish breeding cost is reduced, and the fish quality is improved.

Description

technical field [0001] The invention belongs to the technical field of biological fish fertilizer, and more specifically relates to a special amino acid fertilizer water slurry for aquaculture, and also relates to the preparation of "waste water" in the production process of L-cystine, L-leucine and L-tyrosine A method for amino acid fertilizer water slurry. The fertilizer water slurry is an efficient and environmentally friendly biological fish fertilizer, suitable for freshwater aquaculture of various fish, shrimp, crab, shellfish, etc. technical background [0002] There are three main types of fertilizers commonly used in aquaculture, namely organic fertilizers, inorganic fertilizers, and biological fish fertilizers. Traditional organic fertilizers have their advantages, but the fertilizer effect is slow, the process of being used by plankton is longer, and a large amount of oxygen in the water body is consumed during the decomposition and mineralization process, which ...
