Title:

KNEADING DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/021180

Kind Code:

A1

Abstract:

Paddles (Pn, Pn', Qn, Qn') functioning as kneading members are attached to two rotational shafts (3, 4), which rotate in the opposite direction at unequal speeds, at a predetermined spiral pitch and at a predetermined angle pitch interval so as to form a reverse spiral with one another. An object to be kneaded is kneaded by rotating each rotational shaft. The side surfaces extending in the axial direction of the rotational shaft of each paddle on the rotational shafts are curved in the shape of a concave. The rotational shafts are disposed close to one another such that the tips of the paddles on one rotational shaft enter into the concaved curved surfaces of the opposing paddles of the other rotational shaft when the rotational shafts rotate. A high compression effect and cracking effect are exerted because it is possible to reduce the gap between opposing paddles.
