If a bakery has to deal with a quantity of approx. 20 tons of flour every day, this huge amount can only be accomplished at a fully automated large-scale business, where the flour is conveyed all-automatic. Regarding the wholesale bakery Sehne in Ehningen, near Böblingen the efficiency of the former pneumatic conveying system had been exhausted up to the limit. Therefore, a considerable capacity increase had become inevitable. The solution put into practise by the end of 2007 is brilliant and convincing: An additional pneumatic conveying unit together with a new integrated weighing station had been added to the present conveying unit between the external silos and the former weighing station. Thanks to the almost complete further use of all components of the former solution and the additional insertion of the new unit, it was possible to establish an especially economic and reliable new transport- and weighing concept with considerably increased number of cycles. The extra demand of conveying air is produced by two additional positive displacement blowers manufactured by Aerzener Maschinenfabrik.
