Problems solved by technology

[0004] However, there are defects in the existing method for removing peculiar smell in the production process of amino acid raw powder. The elimination of peculiar smell is not thorough enough, and the elimination efficiency of peculiar smell is low. Through the filtration of gas, the efficiency is slow

Embodiment Construction

[0025] A production process of amino acid raw powder and a method for eliminating peculiar smell thereof:

[0026] (1) Hydrolysis:

[0027] Take 2kg of fish fillet scraps, 5.4l of industrial hydrochloric acid, and 1.8l of water, and put them into a hydrolysis bottle for hydrolysis. Hydrolysis conditions: temperature 106~110℃, hydrochloric acid concentration about 6mol / L, time 20h. After hydrolysis, the hydrolyzate is reddish brown.

[0028] (2) Neutralization and decolorization:

[0029] Stir and cool the hydrolyzate, slowly add 7mol / L lye, control the neutralization end point at pH 3, add waste carbon and new carbon for recrystallization in the previous batch, and decolorize twice, and add 400g of new carbon per batch (about 2 %), stirred at 70-80° C. for decolorization for 30 minutes, filtered, and the decolorized solution was a slightly yellow transparent liquid.

[0030] (3) Concentrated crystallization:

[0031] Adjust the pH of the hydrolyzate to 2.5 with dilute hyd...

Abstract

The invention discloses an amino acid original powder production process and a peculiar smell eliminating method thereof. The production process comprises the following steps of: (1) hydrolysis: hydrolyzing 2kg of fillet leftovers, 5.4l of technical hydrochloric acid and 1.8l of water in a hydrolyzing bottle, wherein the hydrolyzing conditions as follows: the temperature is 106-110 DEG C, the concentration of hydrochloric acid is about 6mol / L, and the time is 20h; and after hydrolysis, the hydrolysate is reddish brown; and (2) neutralization and decoloring: stirring and cooling the hydrolysate, slowly adding 7mol / L alkaline liquor, controlling the neutralization terminal point at pH3, separately adding waste carbon and new carbon for recrystallization in previous batch for decoloring twice, wherein the 400g (about 2%) of the new carbon is added per batch, stirring the mixture at 70-80 DEG C, insulating and decoloring for 30min, filtering the mixture to obtain the decolored liquid which is the slightly yellow transparent liquid. According to the invention, peculiar smell is adsorbed by activated carbon. The physical peculiar smell removal method can ensure that no other mixed impurities are entrained, so that the using effect of a product is better. Then, the activated carbon used in the body is output out of the body through a transmission device, and the activated carbon is immediately replaced, so that the peculiar smell removal effect is better.

Description

technical field [0001] The invention relates to the technical field of amino acid preparation methods, in particular to a production process of amino acid raw powder and a method for eliminating odor. Background technique [0002] Amino acid raw powder is yellow powder. It is completely soluble in water and has strong hygroscopicity. Can improve crop quality and increase yield. It is the first choice for flushing fertilization, foliar fertilizer, liquid fertilizer, amino acid biological fertilizer and various bacterial fertilizers. Widely used in nutrition and health food (amino acid oral liquid, granules, amino acid capsules, fruity amino acid drinks and concentrated drinks, nutritional wine, food for the elderly, etc.), can also be used in candy, pastry, fortified food, baked food, various gravy Dried noodles, condiments (sauce, various soups) are the best additives and basic raw materials to promote the growth of animals and plants. [0003] Amino acids are essential ...
