The sourdough production comprises the use of a flour mixture and the sourdough production in a single- or multi-stage preparation. The development of these two kinds of preparation is based on the consideration of a targeted increase of yeast or the generation of a specific acid with aroma. Zeppelin Reimelt’s batch sourdough system offers this individual system solution.

Flour is pneumatically conveyed into a holding hopper and is then metered by an adjustable conveying screw into the fermenter. Parallel to metering of flour, the mixing water is added. A constant comparison of the quantities metered ensures that the desired mixing ratio is observed. As a third raw material the starter is added. Afterwards, homogenous mixing of the raw materials in the fermenter and the hydration of the flour is carried out. The system allows to adjust several preparation stages with variable dough yield and temperature. After a fermentation time of approx. 12 to 18 hours the finished sourdough can be cooled down in the double-walled fermenter to the desired storage temperature of approx. 15°C. Thus, the sourdough is available for a period of several hours at a constant quality. The doublewalled and insulated stainless steel tanks fulfil the task of a fermenter and that of a storage tank.

An intelligent electrical control system provides operator prompting and regulates the chronological and the technological fermentation process. Only in this way, the baker is released from supervising the process and has time for the essential thing in his bakery: the product.
