<p>The device foresees that from feeding store (1) the beans coffee comes down, throught a drain-pipe (2), into a milling chamber (3) from which the milled coffee, through a side drain-pipe (4), falls into the delivering store (5). When the milled coffee is turned out from the delivering store (5) until to free the photocell (6) ray, the electronic card, included in the device, starts the milling and then it stops the same again at the preordainet time. The electronic card device foresees a working in which the feeder or modulator (16) drives a photocell (6) floodlight (7), the ray emitted by the floodligh is caught by a receiver (8) which transmits the electric pulse to an amplifier (9) from which it is sent to a signal computer (10). Said computer (10) receives furthermore the feeder (16) pulse, and after having elaborated this pulse, the same is transmitted to a first timer (11), to a second timer (12) to a relay (13) and to the milling group motor (14) which is activated and then it stops after a preordainet time to ray closure. And so in prosecution whenever the ray level becomes free. This is allowed by the feeder (15) which feeds the card. <IMAGE></p> |
