Abstract

The invention provides a method for separating feather fibers from a poultry feather raw material. The method comprises four steps, namely washing, stripping, carrying out multistage separation and drying, wherein in the step of multistage separation, the feather fibers are subjected to multistage separation by using slit type screens of different screen slit widths, the fine separation of the feather fibers is realized, more choices are provided for the further full utilization of the feather fibers, and thus, the application is more convenient. In addition, the method provided by the invention only comprises four steps, each step is simple and feasible and does not need complicated and expensive equipment, embodied in that only the step (3) of the four steps adopts the slit type screens as a multistage separation device for the feather fibers, and the slit type screens are common devices for papermaking and are simple in structure, so that the separating operation is simple, convenient and feasible.

Description

technical field

[0001] The invention relates to the field of fiber preparation, in particular to a method for separating feather fibers from poultry feather raw materials. Background technique

[0002] With the development of large-scale poultry farming industry, a large amount of feather by-products are produced. At present, the annual output of feather raw materials in my country is more than 1 million tons. The main component of feathers is β-keratin, and feather keratin molecules are very stable through disulfide bonds, hydrogen bonds and other cross-links. At present, except for the small proportion of down used in the textile industry, the main application of feather is to process it into feather protein powder and add it to livestock and poultry feed. Although feather meal has high protein value, stable supply and low price, it is difficult to digest and Lacking essential amino acids, it is considered to be the lowest value protein material for feed.
