Abstract
Provided is a feather separation system for separating feathers from a product in which feathers are filled into a bag-shaped product of a covering. The feather separation system includes: a cutting part configured to cut the product into individual pieces so that at least a part of the bag-shaped product of the covering is open; a feather separation part configured to separate the individual pieces of the product into the feathers and the covering; and an airflow introduction part configured to introduce airflow to the feather separation part.
Claims15
A feather separation system for separating feathers from a bag-shaped product that has a covering and contains feathers, the feather separation system comprising:
- a cutting part configured to cut the product into individual pieces so that at least a part of the covering is open;
- a feather separation part configured to separate the individual pieces of the product into the feathers and the covering;
- and
- an airflow introduction part configured to introduce airflow to the feather separation part,
- wherein the cutting part is configured to cut the covering of the product so that an area S of the covering of the product is larger than 1 cm2 and less than 400 cm2, and D/L is in a range of D/L<10, wherein D is a diameter of a smallest circumscribed circle of the individual pieces of the cut covering and L is a distance between smallest circumscribed parallel lines of the individual pieces of the cut covering.
A feather separation method for separating feathers from a bag-shaped product that has a covering and contains feathers, the feather separation method comprising:
- a cutting step of cutting the product into individual pieces so that at least a part of the covering is open;
- a feather separating step of separating the individual pieces of the product into the feathers and the covering by a stirring means and airflow;
- and
- a feather collecting step of collecting the separated feathers,
- wherein the cutting step includes cutting the covering of the product so that an area S of the covering of the product is more than 1 cm2 and less than 400 cm2, and D/L is in a range of D/L<10, wherein D is a diameter of a smallest circumscribed circle of the individual pieces of the cut covering and L is a distance between smallest circumscribed parallel lines of the individual pieces of the cut covering.
