摘要

Of general frustoconical shape, it comprises a wall or barrel (10) closed by bases (11, 12), and it can turn around a shaft (2) passing across it via the centre of the two bases (11, 12), the barrel (10) comprising, near the base (11) of larger diameter, at least two openings (13', 14') which can be hermetically obturated by doors (13, 14) and comprising, on the other hand, orifices (15, 16) provided with gates (15', 16') near the bases (11, 12), diametrically opposite the opening (13') for loading and racking off, and on the other hand other valves (18) evenly distributed on the periphery of the base of larger diameter (11) and each comprising a tail (181) provided at its end with a bearing (185) which, during the rotation of the vat (1), comes and rests on a cam (25) integrally attached to the frame (23) at its upper part, which has the effect of compressing the spring (184) which maintains the valve (18) closed, bringing about its opening and thus permitting the evacuation of the gases derived from the fermentation.
