Automation of the raw material handling in a biogas plant

Raw material handling covers the preparation of many different types of raw materials for gas production. For example: liquid manure, silage, sewage sludge, organic waste, straw etc. Upon delivery, the materials are first weighed, and then put into storage. If necessary, the materials are sanitized before being fed into the fermenter in the correct mixing ratio. Siemens weighing technology (SIWAREX) and instrumentation (SITRANS) products and solutions are used in these first steps of the process. The automation and drive technology supports the entire logistics.
