<p>The invention relates to a device which is used to cool fermentation tanks and which can be used essentially in beer production, cooling and maturation. According to the invention, a vertical heat exchanger, which comprises single- or double-wall concentric cylinders, is positioned internally at the centre of a tank. The length and capacity of the aforementioned cylinders can differ depending on the size and shape of the tank. A coolant flows through the cylinders in order to cool the beer wort and the beer and to maintain same within a suitable temperature range. In addition, the double-wall cylinders which form the heat exchanger are interconnected by means of coolant flow and support tubes. Meanwhile, the exchanger is supported by the cone and the walls of the tank by means of tubes which are used for the passage of the coolant and the passage of signals. The fermentation tank comprises three main sections, namely: an upper convex cover, a cylindrical body and a conical base, the tip of which comprises a valve. Moreover, the outer wall and the cone can be provided with a cooling jacket. The invention is suitable for use in devices used to cool and mature beer and, by extension, to ferment wine, whiskey, tequila, rum and vodka, i.e., in general, any type of distilled drink which is produced during wort fermentation using yeast. The invention can also be used as a cooling and fermentation device for milk products.</p> |
