Abstract: Method and machine for preparing beverages, in particular infusions, such as coffee or tea, having a liquid supply source supplying a liquid, in particular water, an infusion chamber and an infusion circuit, which connects said supply source to said infusion chamber; the machine having an infusion circuit with a heat exchanger and a dispensing assembly, which is configured to heat the liquid at a predetermined temperature that is lower than the boiling temperature of the liquid, for example at approximately 90°, before the infusion of the liquid itself on the inside of the infusion chamber.

Abstract: Method, machine and boiler for the preparation of beverages, in particular infusions such as coffee or tea; wherein the boiler has a central tank which delimits a superheating area for a liquid and an outer tank positioned around the central tank so as to delimit a heating area for the liquid and to allow the heating of the liquid in the heating area by means of the heat generated in the superheating area; the heating area having a first outlet for supplying hot liquid, the superheating area having a second outlet for the supply of steam.

Abstract: Apparatus for detecting the coloring of moving tiles for the purpose of dividing their flow into a plurality of flows as a function of the quality of their color. The apparatus detects the color of successive portions of the moving tile and breaks down the detected light spectrum into the three primary colors according to the trichromatic theory. The intensity of each primary color is converted into an electric function by a bank of photoelectric sensors, and this function is processed and compared in a microprocessor with coded signals corresponding to the ideal or optimum coloring that the detected tile should present. The microprocessor emits the signals for automating the division of the flow of scanned tiles into a plurality of flows differing in the quality of the coloring of said tiles.
