Method and relative apparatus for the production of beer
A method, and related apparatus, for producing beer from any types of grains includes activating phenomena of controlled hydro-dynamic cavitation during all the steps of the process, from mashing to hopping, and possibly after yeast inoculation. The present method and apparatus provide a number of advantages over traditional techniques, for example, avoiding the pre-crushing of the malts or the grains, thereby increasing the efficiency of saccharification and of starch extraction, and avoiding the boiling at equal efficiency of the hopping. Another advantage is the opportunity of causing the concentration of gluten to fall in the final product simply with controlled hydraulic processes through electromechanics, and of possibly extending fermentation.
1. A method of producing beer comprising the following steps:
mashing a mix of a liquid and of malt or grains to produce a wort by,
arranging the mix inside a tank, and
moving, through a pump, said mix along a closed circulating path, said closed circulating path being formed by a circulating path connected to the tank so as to cause the mix to move from the tank along said circulating path and to direct the mix again inside the tank for all of a time in which the pump is maintained activated,
wherein said circulating path comprises at least one cavitation reactor configured to generate hydrodynamic cavitation with a subsequent increase in temperature of the mix to a predetermined temperature level;
hopping the wort by,
introducing, in the wort, a pre-determined quantity of hops, at different moments, and
moving, through a second pump, the wort and of the hops along a second circulating path,
wherein the second circulating path comprises at least one second cavitation reactor configured to generate the hydrodynamic cavitation and increase the temperature of the wort in accordance with a pre-determined protocol;
cooling and fermenting the wort after hopping by adding a yeast; and
maturing the fermented wort.
2. The method, as per claim 1 , wherein the steps of the method are activated electromechanically.
3. The method, as per claim 1 , wherein the malt or grains are in uncrushed condition.
4. The method, as per claim 1 , wherein the malt or grains are in crushed condition and held within a basket made of a perforated mesh.
5. The method, as per claim 1 , further comprising filtering the wort after mashing.
6. The method, as per claim 1 , wherein the second circulating path is a second closed circulating path connected to a second tank so as to cause the wort and the hops to move from the second tank along the second closed circulating path and to return to the second tank for all of a time, during which the second pump is active.
7. The method, as per claim 1 , wherein mashing and hopping are performed in the same tank, and wherein the pump and the second pump are the same pump, the circulating path and the second circulating path are the same circulating path, and the at least one cavitation reactor and the at least one second cavitation reactor are the same cavitation reactor.
8. The method, as per claim 1 , wherein mashing and hopping are performed in separate tanks, and wherein the pump and the second pump are different pumps, the circulating path and the second circulating path are separate circulating paths, and the at least one cavitation reactor and the at least one second cavitation reactor are separate cavitation reactors.
9. The method, as per claim 1 , further comprising the step of maintaining the predetermined temperature level by providing a cooling system of the tank that comprises a wet sleeve that surrounds the tank or a cooling coil within the tank.
