FERMENTER FEED SYSTEM FOR FERMENTABLE BIOMASS OF A BIOGAS SYSTEM AND METHOD FOR OPERATING THE FEED SYSTEM

摘要

A fermenter feed system for fermentable biomass of a biogas system comprising at least one fermenter, and a delivery and treatment device located between a biomass depot and the fermenter. A mechanical cell breakdown apparatus (6) processes the biomass for delivery (5, 10, 11, 14, 34) to the fermenter (18,19) which includes an outlet opening (23) with a diameter. The diameter may be varied by an adjustable actuating member (32) according to at least one sensor (26) for detecting an operational parameter value of the cell breakdown apparatus (6) or the biomass. A diameter regulator (25) receives an output signal from the sensor as an actual parameter value and compares it to a predetermined target value (28). The actuating member (32) is activated when the actual value falls below the target value to make a predetermined change to the outlet opening diameter.
