[0005] In addition, Japanese Patent No. 2009298737 discloses a method for producing keratin from poultry feathers. The process disclosed and the use of medicaments are cumbersome, and the sediment must be separated by constantly adjusting the pH value, and the overall proportion of water bath used is high. 1g of feathers is mixed with 50ml of thioglycolic acid solution (alias TGA), which requires a lot of water resources and the preparation of medicaments; finally, the pH value is adjusted to 3.5 with acetic acid, and the resulting keratin product is acidic, which is not suitable for people's livelihood products (such as makeup, cosmetics, etc.) hair and skin care products)
[0006] In addition, both of the above two methods collect sediments by centrifugation, and the keratin products must be separated by high speed (10000rpm), and this kind of high speed centrifugation equipment is laboratory-grade equipment, not only has a small capacity and limited output (only about 1L solution), and the high cost of equipment is not conducive to mass production; moreover, the aforementioned known methods for extracting keratin from feathers, from the reaction system to the filtration system to the centrifugal system, all operate with independent equipment, so the equipment used High cost, easy to cause wear and tear in the process, and it is not easy to clean the machine and maintain it

Abstract

The invention discloses a method for obtaining keratin from feather. Feather materials are used as raw materials, a reaction tank containing inner and outer tanks and the appropriate ratio of reagentsare utilized to sequentially soften and dissolve the feathers, through the quick completion of processes of reaction, dissolution, centrifugation, and filtration, keratin solution can be produced ina high-efficiency and mass production mode, feather waste can be reused and the problem of low added value will be improved.

Description

technical field [0001] The present invention relates to a method for extracting keratin from feathers, in particular a method for extracting keratin suitable for the field of livelihood and chemical industry, with the mode of energy saving, environmental protection and high efficiency, so that the existing feather fine washing equipment can be used at low cost. Mass production is helpful for related businesses to process and utilize feather waste. Background technique [0002] The materials of down products are mainly taken from the feathers of waterfowl and poultry (such as ducks and geese), and the feathers of waterfowl and poultry are divided into down (Down) and feathers (Feather) containing feather stalks / rachis. Feathers are not as effective as down and have a high thermal insulation effect, and they account for a large proportion (about 90% of a duck or goose's body), and most of them are not suitable for filling in down products. After high-pressure hydrolysis, it i...
