German term or phrase: Anmaischgrube
This is a specialised term in biogas production. It seems to be a mixing container. Does anyone know the proper name?

complete mix digester
Explanation:
Not really my area, but these things look relatively simple, at least in terms of the subsystems involved.

Look at the link for a description where they say:

"A complete mix digester converts organic waste to biogas in a heated tank above or below ground. A mechanical or gas mixer keeps the solids in suspension. Complete mix digesters are expensive to construct and cost more than plug-flow digesters to operate and maintain.

Complete mix digesters are suitable for larger manure volumes having solids concentration of 3 percent to 10 percent. The reactor is a circular steel or poured concrete container. During the digestion process, the manure slurry is continuously mixed to keep the solids in suspension. Biogas accumulates at the top of the digester. The biogas can be used as fuel for an engine-generator to produce electricity or as boiler fuel to produce steam. Using waste heat from the engine or boiler to warm the slurry in the digester reduces retention time to less than 20 days."

So, this just might be what you are looking for.
