We are going to be running primarily slurry but with grass silage/maize/wholecrop etc in a 250kW digester.
The problem lies in that our tank (like many) is above ground, and to feed with an auger it will need to take things up 8m. We are aware this is a weak point in the design, and are interested in other options, and specifically we have considered Vogelsang which I understand conditions and mixes the feedstock with recirculated digestate, so that it can be pumped into the tank. However, I know pumps also have their own problems, and it's probably a fair bit messier to clean/fix than the auger.
Just wondering if we are missing anything, or if anyone has experience of either of these systems and could offer opinions/advice. An auger will block from time to time, and I think a pump will also. Ideally we'd want something with maximum uptime and reliability.
