DEVICE FOR MECHANICAL MODIFICATION OF CHICKEN FEATHER Russian patent published in 2009 - IPC B68G3/08 

FIELD: food industry, equipment.

SUBSTANCE: proposed invention deals with equipment for mechanical processing of animal fibres such as feather and down raw materials for the needs of bedding products manufacture. The device for mechanical modification of chicken feather is composed of a raw material loading unit, a storage hopper with a free drop chamber, a conveyor belt and a working roll with toothed notches enabling pickup of feather and application of indentations on the stem inside surface to provide for additional incurvation of the feather. The working roller is equipped with a mechanism enabling adjustment of the intensity of pressure applied to the feather stem. Raw material load and processed feather discharge may be performed by the same valve-equipped structural unit. The proposed device for mechanical modification of chicken feather provides for improved filling properties of the feather raw material which enables its application in the capacity of a relatively inexpensive filler for manufacture of high grade bedding textiles.

EFFECT: improved filling properties of the feather raw material which enables its application in the capacity of a relatively inexpensive filler for manufacture of high grade bedding textiles.
