Abstract
A kneading apparatus has two rotary shafts mounted to undergo rotation in opposite directions at unequal speeds. Cubic-shaped kneading members having the same shape and size are detachably mounted to the rotary shafts so as to be arranged helically with an inverse helix from each other at a predetermined helical pitch and at predetermined angular pitch intervals for kneading an object during rotation of the rotary shafts. Each kneading member has side surfaces extending parallel to a rotational axis of the rotary shaft and front and rear surfaces extending perpendicular to the rotational axis. The side surfaces of each kneading member is curved in the shape of a concave. The rotary shafts are disposed close to one another so that tips of the kneading members on one of the rotary shafts enter into the concave curved surfaces of the opposing kneading members of the other of the rotary shafts without the opposing kneading members contacting one another during rotation of the rotary shafts.
