Abstract: A kneading device 1 comprising an inner cone 2 and an outer cone 3, wherein the inner cone 2 and the outer cone 3 defines a space 4 in between the inner cone and the outer cone; from a horizontal plane the inner cone 2 inclines and forms an angle ic; from the same horizontal plane the outer cone 3 inclines and forms an angle oc; where the inner cone 2 has an opening in a bottom of the inner cone 2; where both the inner cone 2 and the outer cone 3 continue vertically in an inner extension 5 and an outer extension 6, respectively, wherein a space in between the inner extension 5 and the outer extension 6 is a gap E; where scraping wings 7 extend from a center portion 8 of the kneading device 1 and through the inner cone 2 and the outer cone 3 and towards, but not fixated to, an inner wall 9 of the outer cone 3; and where the outer cone 3 inclines more than the inner cone 2, when viewed from the horizontal plane, so that angle oc>angle ic.

Abstract: The present invention describes a kneading device (1) comprising an inner cone (2) and an outer cone (3), wherein the inner cone (2) and the outer cone (3) defines a space (4) in between the inner cone and the outer cone; from a horizontal plane the inner cone (2) inclines and forms an angle ic; from the same horizontal plane the outer cone (3) inclines and forms an angle oc; where the inner cone (2) has an opening in a bottom of the inner cone (2); where both the inner cone (2) and the outer cone (3) continue vertically in an inner extension and an outer extension (6), respectively, wherein a space in between the inner extension (5) and the outer extension (6) is a gap E; where the inner cone (2) and the outer cone (3) are connected by scraping wings (7) extending from a centre portion (8) of the kneading device (1) and through the inner cone (2) and the outer cone (3) and towards, but not fixated to, an inner wall (9) of the outer (1) cone (3); and where the outer cone (3) inclines more than the inner cone
