A tomato peel material acidification system (10) including a receiving tank (32), a pump (36), acid injection devices (46, 48), mixing devices (38, 39), and a return line (52) for recirculating tomato peel material with an acid level that is too high. PH sensor probes (56, 58, 60) test the pH level of the tomato peel and acid mixture and appropriate controls direct the opening and closing of valves (50, 51, 54, 55) to re-direct the mixture back into the receiving tank. |
