Embodiment 1

[0026] Such as figure 1 As shown, Embodiment 1 of the present invention provides a kind of method that meat and bone powder prepares amino acid powder, specifically comprises the following steps:

[0027] Step 1, mixing meat and bone meal and hydrochloric acid in a certain proportion and fully stirring, the solid-liquid mixture formed is called mother liquor, usually the mixing mass ratio of meat and bone meal and hydrochloric acid is 1:2.5~3;

[0028] Step 2, adding alkali to the mother liquor, adjusting the pH environment of the mother liquor to be weakly acidic, adding ammonia water to the mother liquor in this embodiment, the mixing volume ratio of mother liquor and ammonia liquor is about 3:1; ammonia liquor is a kind of weak alkaline liquid, After adding the mother liquor containing hydrochloric acid, no obvious chemical reaction will occur, and the pH of the mother liquor is adjusted to a weakly acidic environment of 6-7 by the alkali neutralization of ammonia water.

Abstract

The invention provides a method for preparing amino acid powder from meat and bone meal. The method comprises the following steps of: mixing meat and bone meal with hydrochloric acid according to a certain proportion and fully stirring to form mother liquor; adding alkali into the mother liquor, and adjusting the PH environment of the mother liquor to be weakly acidic; and introducing high-temperature steam into the mother liquor, and forming granular amino acid through the drying effect of the high-temperature steam. The yield of the amino acid powder prepared by adopting the method is high, and the wall sticking phenomenon is obviously reduced compared with that of a drying tower spray drying mode, so that the waste of raw materials is less, cleaning is hardly needed in a production period, and the production efficiency is obviously improved. In addition, the adopted equipment is relatively simple in structure, preparation conditions are easy to arrange and control, the production cost of the amino acid powder is reduced, and the economic benefit of amino acid powder preparation is improved.

Description

technical field [0001] The invention relates to the technical field of amino acid powder production, in particular to a method and equipment for preparing amino acid powder from meat and bone powder. Background technique [0002] Amino acid powder is a powdery substance with a wide range of uses. It can be used as a feed additive for livestock and poultry breeding, and can also be used as an organic fertilizer in planting. In the prior art, amino acid powder is usually made of animal fur, hair, etc., and is dried after microbial fermentation and acid-base hydrolysis. [0003] At present, the harmless treatment methods for dead livestock and poultry carcasses include high-temperature method, which is to extract the oil in the dead livestock and poultry carcasses at high temperature, and the separated products include oil liquid and slag, and the slag is squeezed by a press and crushed The final product after crushing is meat and bone meal, which can also be used as a raw mat...
