Abstract:
1. A machine for dispensing fluid coloring products, each having a different color, to form a finished product having a desired color tone corresponding to a determinate formula, comprising at least a plurality of tanks each of which is configured to contain one of said fluid coloring products having a determinate color, a determinate number of delivery circuits, more than two, connected to said tanks, wherein each of said delivery circuits comprises at least a delivery nozzle and a motorized pumping member, to deliver determinate quantities of said fluid coloring products in a determinate delivery time inside a container, and an electronic control circuit, provided with a central process unit associated, or associable, with at least a first electronic memory in which are memorized the formulas which define the color tones that can be obtained, said electronic control circuit being configured to control said delivery circuits so as to cause the selective delivery of said fluid coloring products from said tanks to said container, wherein said electronic control circuit also comprises two electronic actuation circuits, each configured to be selectively associated to each motorized pumping member of said delivery circuits, so as to selectively cause the simultaneous drive of two of said motorized pumping members and wherein said central process unit is programmed so as to reduce to a minimum the overall delivery time, by selectively coupling each of said two electronic actuation circuits to one of said motorized pumping members, as a function of the formula corresponding to the desired color tone.
