Abstract: Method for the production of a polyphenolic composition from barley malt, including the fundamental steps of: grinding of the malt grains and splitting into two portions, 20% and 80%; mixing each of the two portions with water to obtain an A mixture and a B mixture, the A mixture being prepared with the 20% portion to obtain a mixture of the malt in water at a final concentration between 9.5% and 20%, the B mixture being prepared with the 80% portion to obtain a mixture of the malt in water at a final concentration between 33% and 60%; thermal cycle; separation of the liquid component from the solid component; boiling of the liquid component and the addition of hops; rapid cooling of the wort; storage; in which said thermal cycle consists of a first phase and a second phase, in which the first phase applies to the 20% portion (Mixture A) and the second phase during which Mixture B is added to Mixture A.

Abstract: A method for curving an elongated piece uses a digital system which includes a control console having a programmable processing unit and a screen for displaying data and a camera connected with the processing unit and configured and positioned for acquiring images of the elongated piece. In accordance with the method, the profile of at least one virtual template of curvature is stored in the processing unit and a real image of the elongated piece is detected. The profile of the virtual template and the real image of the elongated piece are reproduced and compared in real time. The roller curving machine is driven and the curvature and the geometric configuration of the elongated piece are matched with the profile of the virtual template of curvature.
