An elemental and general process automatic control system of continuous fermentation was investigated.In this report, the maintaining temperature (T), the holding cell(Y) and the progress of fermentation (S) were determined as feed back elements, and the correcting temperature (T') and the feed rate (F) were determined as the control elements, and each element was discussed.In the continuous fermentation of single or multiple batches of mixed type and of reuse tyope, the mutual relation between Y and S under each feed rate at the stational line was experimentally obtained. The general relation between F and S in mixed type was formulated. From this, a correcting feed rate was calculated in the case where Y and S measured at the standard feed rate had deviation, and also a correcting time was determined from the cycle time (θ).As to the control system by correcting temperature (T'), a basis for the control system in which Y and S were the feed back elements was established with consideration to the correcting temperature under the standard maintaining temperature (T) in the continuous process.In the process control of continuous alcoholic fermentation with molasses, the good results were obtained by operating with multi-position on-off control, in a pilot plant, in which Y at the first batch and S at the last batch were fed back and then connected to the correcting operation under T' and F.
