Patent number: 5187097Abstract: The disclosure is directed to a large composting system as well as to a new composting method for the automatic production of compost. A mobile layer rearranging unit includes a conveyor system which is changeable with respect to length can be remote-controlled so that the influx of rotting matter is optimized according to throughput and rotting time and the rot loss is compensated for by repeatedly restoring the complete rot height. The required space requirement is less than before. Any mechanical intervention has a loosening effect, particularly in that the working device comprises upwardly working digging and conveyor wheels. All important parameters for the compost ripening can be monitored via free programming as well as by control by the system maintenance personnel.Type: GrantFiled: March 23, 1990Date of Patent: February 16, 1993Assignee: Buehler AGInventors: Heinrich Weber, Falko Lehrmann, Hermann Hofer, Werner Vogel, Peter Mueller
