<p>An apparatus for continuously making extruded pasta products, such as spaghettis, comprising a device (26) for sensing the input power to an electric motor (19) which drives a screw (17) for forcing a dough through the extrusion plate (16), and a circuit (27) which generates a first signal indicative of the instantaneous value of the input power. The apparatus further comprises a circuit (28) comparing said signal with a reference signal whose value is indicative of the power that the motor (19) would absorb where the dough being extruded was in an optimum condition of texture. In the event that, from the comparison with the reference signal, a plus differential appears, the apparatus would operate the valving member (10) of the water feed line (9) to increase the flow, change the water-to-flour ratio, and make the dough texture thinner. On the contrary, the apparatus would operate the valving member (10) of the water feed line (9) to reduce the water infeed and thereby make the dough texture thicker. Thus, consistent quality can be ensured for the product, and the control arrangement, being based on detection of the input power to the motor (19), made to perform accurately and reliably.</p> |
