<p>Discontinuous wort boiling system for use in beer breweries uses three heat exchange processes. In the first, the liquor is heated to 78 deg. C followed by storage in a first tank. The second heat exchanger raises this temperature by hot vapours to 99 deg.C for a second storage tank. In a third heat exchange process, the strained wort is preheated to 95 deg.C by the liquor of 99 deg.C and recycled to the first storage tank. - Arrangement utilises the thermal energy of the vapours, produced by the boiling either by direct recycling or by using the surplus for extraneous hot water prodn. EPAB- EP--80706 B Process for discontinuously cooking wort in the production of beer, wherein the clarified wort is cooked, preferably under low pressure, and after cooking is cooled in a first heat exchange process for further use for beer production, cooling water being heated to the temperature of brewing water in this first heat exchange process, and the energy of the vapour produced in the cooking of the wort being moreover used in a second heat exchange process, characterised in that the heated brewing water is further heated in the second heat exchange process by the energy of the vapour, the clarified wort is further heated prior to cooking by this further heated brewing water in a third heat exchange process and the brewing water cooled in the third heat exchange process is heated again in the second heat exchange process by the energy of the vapour, etc. (5pp) USAB- US4483881 A Wort is discontinuously boiled for beer prodn. by A) as known a) boiling refined wort under slight press. and cooling it in a 1st heat exchanger process (HEP) with b) heating the cooling water to a predetermined temp. and B) a) reheating the heated water in a 2nd HEP by the energy arising from the vapours of the wort boiling, b) heating the refined wort before boiling with the reh reheated water in a 3rd HEP and c) further heating in the 2nd HEP the water cooled in the 3rd HEP using the energy arising from the vapours from the boiling. - The water heated by the vapours from the boiling in the 2nd HEP is pref. collected in a suitably heat insulated, tank for use in the 3rd HEP. The water is heated to 78 deg.C in the 1st HEP, to 99 deg.C in the 2nd HEP and the refined wort is heated to 95 deg.C in the 3rd HEP while cooling the water to 78 deg.C.</p> |
