<p>The apparatus comprises a refrigerated reactor (2) with mechanical agitator (8, 9), which has a first duct (14a) associated with its inlet (6) and a second duct (14b) associated with its outlet (7), both ducts (14a, 14b) being connected to a line (13) for feeding a blocking agent. The ducts (14a, 14b) have adjustable regulation and cut-off valves (15a, 15b, 16a, 16b) coordinately controlled to allow the cumulative passage of the intended amount of blocking agent. The valves (15a, 15b, 16a, 16b) are left unchanged, or the valves (15a, 16a) associated with the input are opened or closed further, or the valves (15b, 16b) associated with the output (7) are closed or opened further, if the value of the solid part at the output from the system is correct or higher or lower than the intended one, indicating a reaction which has extended for too long or too short a time.</p> |
