Abstract
The invention relates to a horizontal tank-type container, particularly for use in winemaking, the beverage industry and the preparation of alcohol. The upper portion of the container is of a substantially circular cylindrical shape. The invention resides in the container being pear-shaped or escutcheon-shaped in cross section normal to the longitudinal container axis, with the narrow portion pointing downward. This enables the container to be conveniently emptied and easily cleaned.
Claims14
A wine tank for stationary use in a winery, said tank comprising
- an upper tank portion corresponding substantially in shape to a major portion of a circular cylinder having a substantially horizontal axis,
- stationary supporting means for supporting said tank in a stationary position with said axis substantially horizontal,
- a lower tank portion of a substantially tapered form and having a pair of side walls connecting smoothly with said upper tank portion and extending downwardly therefrom while converging toward each other,
- said side walls ranging from zero curvature to a slight curvature having a radius of curvature which is substantially greater than the radius of curvature of said upper tank portion,
- each of said side walls extending downwardly at an angle of at least 30.degree. relative to the horizontal,
- and a bottom wall portion substantially in the form of a circular cylindrical segment into which the lower portions of said side walls merge,
- said bottom wall portion being connected between the lower portions of said side walls and constituting a discharge drainage trough,
- said downward angle of at least 30.degree. of said side walls being sufficiently great to cause discharge of wine pomace by gravity while minimizing the accumulation of wine pomace on said side walls.

A wine tank for stationary use to hold grape must in a winery, said tank comprising
- an upper tank portion corresponding substantially in shape to a major portion of a circular cylinder having a substantially horizontal axes,
- stationary supporting means for supporting said tank in a stationary position with said axis substantially horizontal,
- a lower tank portion of a substantially tapered form and having a pair of side walls connecting smoothly with said upper tank portion and extending downwardly therefrom while converging toward each other,
- said side walls being in the form of converging planes,
- each of said side walls being at an angle of at least 45.degree. relative to the horizontal to cause the discharge of wine pomace along said side walls by gravity while minimizing the accumulation of wine pomace on said side walls,
- a bottom wall portion substantially in the form of a circular cylindrical segment into which the lower portions of said side walls merge,
- said bottom wall portion being connected between the lower portions of said side walls and constituting a discharge drainage trough,
- juice outlet means connected to said tank along one of said side walls,
- a rotary conveyor screw rotatably mounted in said trough for conveying and discharging wine pomace toward one end of said trough,
- a selectively openable opening at said one end of said trough for discharging the wine pomace therefrom,
- power drive means connected to the opposite end of said rotary conveyor screw for rotating said screw,
- and a rotary agitator rotatably mounted in said upper tank portion and having a rotary axis coinciding generally with the axis of said circular cylinder.
