The system comprises: a tunnel (2), along which the pasta to be treated is fed, two banks (8, 8') of fins extending longitudinally within said tunnel (2) and traversed in a single direction by a thermal fluid, one bank (8) being traversed by heating fluid introduced at that end of the tunnel from which the pasta leaves, the other bank (8') being traversed by cooling fluid introduced, at a temperature less than the dew point, at that end of the temperature in which greatest condensation is desired, a pair of sensors (22, 24) associated with the bank of fins (8) traversed by the heating fluid, to measure the air temperature at the two ends of the tunnel, a pair of sensors (22', 24') associated with the bank of fins (8') traversed by the cooling fluid, to measure the air humidity at the two ends of the tunnel, a sensor (20') positioned in the cooling fluid entry pipe (10') to measure its temperature, and at least one temperature controller (18, 18') connected to said sensors (22, 22', 24', 20') to control, by regulator means (14, 14', 16, 16'), the temperature of the thermal fluids and their flow rate in order to obtain a predetermined temperature difference between the entry and exit of each bank (8, 8'). |
