Method for processing and collecting down feather from feather and rinsing down feather

Abstract

The invention discloses a method for processing and extracting eiderdown from feathers and washing eiderdown. The method comprises the steps of carrying out feeding, extracting, dust removal, stem absorption, washing, rinsing, dehydrating, drying, cooling, impurity removal and packing on the feathers. The eiderdown extraction comprises: adopting an eiderdown extracting tower, throwing the feathers into the eiderdown extracting tower, and making the rotation speed of a stirring device in the chenille eiderdown extracting tower be 40-50 turns / min; the washing procedure comprises: putting the feathers into water added with a washing agent, stirring and cleaning the feathers; the rinsing procedure comprises: cleaning the washed feather slurry repeatedly by water; and the drying procedure comprises: drying the dehydrated feathers to 50 to 70 percent of dryness through steam, dampening the feathers, drying the feathers by the steam, and repeating the procedure frequently. The method reduces the down loss rate to 1 percent from 5 percent, and improves the high value contents of down in a feather sheet from 82 percent to 98 percent so as to reduce down mechanical loss and achieve the effects of improving quality and reducing loss. The fluffy degree of the 90 percent eiderdown is improved from 13 cm to 18 cm.

Description

technical field [0001] The invention belongs to a method for processing feathers, in particular to a method for processing down feathers and washing down. Background technique [0002] my country has very rich feather resources, and the output of feathers accounts for about 6.6%-7.6% of the live ducks and geese. If all the feathers from all over the country can be processed and utilized, it can increase a great income for the poultry industry. Washed finished down is not only one of the traditional main export livestock products, but also a scarce raw material for the domestic down products industry. The purpose of down separation is to separate the down and raw flakes from the raw feathers and classify and file them, so as to meet the requirements of various filling materials in the processing of products of different specifications in the clothing and bedding industries. The existing feather processing and raising is to put the feathers into the raising tower, and under t...

Problems solved by technology

The existing feather processing and raising is to put the feathers into the raising tower, and under the action of the stirring device, the down and the hair stem are separated. At present, the high-value separation rate of the down in the highest level of feather flakes is 82%, and there are still quite a few. Part of the feathers cannot be separated, resulting in a waste of resources; secondly, when drying the down, use high-temperature steam at 130°C to dry the down at one time. Although the time is short, the effect of complete sterilization cannot be achieved. Into a burnt paste, which deforms and damages the velvet
