Abstract: A process for producing leaven and a device especially suited to carrying out this process are to be improved in a way which ensures that a supply of leaven is constantly available in a quantity which can be predetermined and matched with the baking requirements, with only a modest technical outlay. This is accomplished according to the invention by placing the leaven preparation in an initial fermenter (2-4) in the fermenting chain and transferring it to the subsequent fermenter when a specific cycle time (t1-t4), which is the same for all the fermenters, has elapsed. Once the dough has passed through all the fermenters in the chain, it is transferred to a storage container (5); the sum of the cycle times (t1-t4) equals the total time of passage (tR) of the leaven.
