PURPOSE:To provide a large space in a vessel to allow to supply a large amount of raw material and to improve the mixing capacity by providing the agitation shaft having agitation blades so as to be inclined or parallel and excentric to the center axis of the vessel. CONSTITUTION:The scraper 7 which rotates along the inner surface of the vessel 2 having an opening and closing cover 6 provided on the upper opening of the vessel, and the agitation shaft 3 provided with plural agitation blades is projected from the bottom of the vessel 2 so as to be inclined or parallel and excentric to the center axis of the vessel 2. As a result, a large vacant space is made in the vessel. Consequently, a large amount of raw material is supplied at a time and the mixing capacity of the agitator is, as a whole, improved because the clearance between the agitation blades and the inner peripheral surface of the vessel in the confronting side to the vacant space part becomes small. |
