1. A processing method for feather meal, characterized in that it uses weakly alkaline salts and weakly acidic salts as redox agents, yeast as a catalyst, and the disulfide bond between the molecular chain of keratin in feather meal The hydrogen and sulfur undergo a redox displacement reaction to break the disulfide bond, and then the feather meal is processed by puffing mechanical treatment.

2. A method for processing feather meal according to claim 1, characterized in that the weak alkali salt can be sodium thiosulfate, or sodium sulfate, or betaine, or sodium carbonate, or sodium glutamate, or Sodium sulfite, or a mixture of any of them.

3. A method for processing feather meal according to claim 1, wherein the weakly acidic salt can be sodium hypochlorite, or ammonium acetate, or sodium diacetate, or a mixture of any of them.

4. The method for processing feather meal according to claim 1, wherein the blending amount of weakly alkaline salt and weakly acidic salt is 1-3% of the weight of feather meal. The method for processing feather meal according to claim 1, wherein the blending amount of the weakly alkaline salt accounts for 60-70% of the total weight of the weakly alkaline salt and the weakly acidic salt. 5. The method for processing feather meal according to claim 1, wherein the added amount of yeast is 1.5-2.0% of the weight of the feather meal. The method for processing feather meal according to claim 1, wherein the temperature of the oxidation-reduction reaction is 25-40°C. 8.
