<p>A system (100, 200) is described for correcting constant volume acidity of fermentative media for the production of organic acids, which comprises a fermenter (1) provided with a pH sensor (P1), a filtration module (2) provided with a filtering element, an addition vessel (3) provided with a main metering element (4), and a heat exchanger (5). Operation of the system (100, 200) is controlled by a controller (CT). As soon as the sensor (P1) detects a reduction in pH to below the ideal values for producing organic acid, the controller (CT) calculates the amount of fermentative medium to be withdrawn from the fermenter (1) and said amount is conveyed to the vessel (3) in order to be alkalinized and returned to the system. Arrangements of the system with more than one fermenter are also described. The process for correcting acidity used by the system (100, 200) of the invention is likewise described.</p> |
