Rendering Hydrolyzer Model Is SRSJ1228-9 Feather Meal Processing Equipment

They can be blended alone or in combination. Mixed and added, the weakly acidic salt can be sodium sulfite, or sodium hypochlorite, or ammonium acetate, or sodium diacetate, etc. and then becomes a weakly acidic salt, which can be added separately or mixed with each other. In the fermentation chamber, the weak base salt first undergoes redox substitution reaction with the sulfur and hydrogen in the keratin molecular chain in the feather meal, so that the disulfide bond is broken, and the weak acid salt reacts with the remaining weak base salt after the reaction. The neutralization reaction and the expansion process are to terminate the acid-base reaction and replacement process and stabilize the properties of the product after the reaction. The feather protein powder obtained by the feather meal processing method of the present invention was measured by the L-8500A amino acid analyzer by the Animal Husbandry Research Institute of the Chinese Academy of Agricultural Sciences to determine the content and appearance of amino acids.

The true metabolic rate results are shown in

Table 1. See Table 2 for comparison of amino acid metabolism rate with other protein feeds. Table 1 Measured value of amino acid metabolism rate (chicken) in feather protein powder (unit %)

Table 2. Comparison of amino acid metabolism rate with other feeds (%) It can be seen from Table 1 that the total amino acid content of feather protein powder is 55.08%, the apparent metabolic rate of total amino acids is 80.25±5.58%, and the true metabolic rate of total amino acids is 86.43±5.58%. The apparent metabolic rate of various amino acids varies from 64.98-85.52%, the true metabolic rate of various amino acids is 74.88-89.62%, among which the true metabolic rate of lysine is 82.66%, methionine is 83.59%, and cystine is 85.36%. Among all amino acids, the metabolic rate of glycine and arginine is the highest, followed by isoleucine and serine, and alanine is the lowest, but it is much higher than the amino acid metabolic rate of puffed and hydrolyzed feather meal measured by our laboratory. It is also higher than the metabolic rate of amino acids in unconventional protein feed such as hydrolyzed leather protein powder, DDG, DDGS. The feather protein powder processed by the present invention was tested by the National Feed Quality Supervision and Inspection Center (Beijing), and the results are shown in Table

Table 3. Inspection report of National Feed Quality Supervision and Inspection Center (Beijing) The feather meal processing method of the present invention is simple and easy to operate, so that a large amount of discarded feathers that cause environmental pollution becomes a high-quality protein resource that animals can easily absorb. It can not only replace imported fish meal, but also partially solve the problem of animal feed protein shortage. , Can also solve the problem of environmental pollution.
