Ponndorf Anlagenbau Germany: improved technologies, perfection and success in drying plants since 1902.
As a medium-sized family-owned enterprise we succeeded in keeping our tradition and, at the same time, providing technical progress in the form of customized plants. The pursuit of improved technologies, perfection and success, is for the company Ponndorf - founded in 1902 by Wilhelm Ponndorf - not only a long tradition but the basis of the company's philosophy. It has been tried and tested now in the fourth generation in the brewing industry, in the starch industry, in the disposal engineering as well as in the wood industry.
From drying plants for a range of different substances right up to unique systems constructed and manufactured according to the requirements of our customers - they all excel in their overall performance, starting from the selection of high-quality materials via expert workmanship through to perfect functioning. A special Ponndorf service, spanning many industrial fields, is working out high-tech engineering solutions according to customer specifications. S/G - Yeast Dryers For drying of yeast, we offer single cyclinder sump driers as illustrated in the flow scheme to the right. The cylinder of the drier only collects a small part of the yeast contained in the drier trough. The yeast coat, formed on the rotating cylinder, is scraped off by a hydraulically operated blade and drops into a crushing screw, placed beneath. Then the dry yeast is pneumatically conveyed to the dry yeast silo. Technical Data: - heated by steam - 50 to 1200 kg/h wet yeast drying performance (from 85 % down to 10 % relative humidity) - variable rotational speed control of the cylinder - hydraulically operated scraper bar and dipping trough - constant product quality due to precise rotation of cylinder - fine grinded cylinder made of steel (type S) or cast iron (type G) - robust slip on gear mechanism (type S) or hydraulic drive system (type G) - mounted on a sturdy supporting frame.
