Abstract
The invention relates to a tank-type container for the processing of wine grape must, particularly a fermentation tank for red wine must. The tank is equipped with a slowly rotating agitator having a plurality of longitudinally spaced blades disposed the full length of its shaft extending parallel to the longitudinal axis of the tank. The invention resides in at least one section, preferably an outward section, of the cross-sectional area of the agitator blades parallel to the agitator shaft being larger than the cross-sectional area which is normal to the agitator shaft. The pomace cap floating on the surface of the juice is disintegrated and punched down into the body of the juice by means of the flat wide blade sections.
Claims13
A horizontal tank-type wine fermentation container for the processing of wine grape must, in which the must includes grape juice with a pomace cake floating on the juice, said container comprising
- a generally circular-cylindrical fermentation tank having a generally horizontal longitudinal cylindrical axis,
- a rotary agitator rotatable in said tank about a rotary axis parallel to said cylindrical axis of said tank,
- said agitator including a rotary shaft having a plurality of longitudinally spaced agitator paddles extending outwardly from said shaft and disposed along the full length of said shaft,
- power means for rotating said agitator shaft at a slow rotary speed ranging from one half to twenty revolutions per minute,
- said agitator paddles including at least outer sections having a cross-sectional width parallel to the agitator axis and a cross sectional thickness transverse to said width,
- said cross sectional width parallel to the agitator axis being much greater than said cross-sectional thickness,
- whereby said paddles efficiently break up the pomace cake into pieces and efficiently propel such pieces through the grape juice component of said wine grape must,
- said agitator having a large diameter ranging between one and five meters,
- said tank having a generally trough-shaped drain portion projecting downwardly therefrom,
- said drain portion having a partial circular-cylindrical shape,
- and a rotary discharge screw installed in said trough-shaped drain portion,
- said drain portion having a discharge opening therefrom.

- said outer sections of said paddles having tip portions provided with scrapers of an elastic rubber-like material to enable said scrapers to engage and scrape the interior wall surface,
- the rotary axis of said agitator shaft being located below the cylindrical axis of said tank.
