Die Höhe des Waschwasserspiegels wird hierbei nach Bedarf durch entsprechene     Einstellung   des Rohres a geregelt.

 in the front wall is closed with a blind cover. The pipe a b1, bent at a double right angle, is now turned to the highest position and the washing process is initiated by opening valve 1, in that the dirty water flows out through the slot in pipe 8 and valve 1 by slowly turning the drum and pure water is constantly flowing through the openings of the Rohres flows. The height of the washing water level is regulated as required by setting the pipe a accordingly.



   As soon as the exiting water is pure, washing is stopped. All open valves are closed and the drum is positioned so that the opening for the sieve body

   Removing the lid leveled the sand in it and started the filtration all over again. Half of the tests show that the oval grated body can also be left in the filter after washing.



   The washing of the filter can also be started in such a way that at \ entu / t em Schtauch with Holländer connected and pure water is driven from bottom to top through the sieve body and the sand, so that the largest dirt lying on the surface of the stand is first sloughed off and through the slotted tube is washed away. whereby the washing process can be shortened somewhat.



   For the purpose of complete cooling of the sand when filtering sugar juices, the screen body is closed for the most part on its side facing the axis of the drum and only the side
