Vogelsang solid matter feeder:
Reliable digester feeding for efficient biogas production

Biogas technology needs to be secure and efficient at all times to enable cost-effective plant operation. Digester feeding plays a key role here. Wet feeding is the ideal form of solid matter feeding. For this reason, we have developed systems that add solid matter in mashed form to foster bacteria. This increases the gas yield and reduces the energy needed for mixing, stirring and pumping; it helps your plant to operate efficiently and economically.
