Gas Mixing a Digester Crust

This is an edited portion (with timings) of a much longer video illustrating how effectively gas mixing in a digester can break up a hard crust, which is a typical problem with a badly-mixed digester. Apologies for the quality: it was taken from an old video tape. Although watching cow muck doesn't seem terribly exciting, it is pretty amazing how a low parasitic energy gas mixing system can break up the crust that a man can stand on, even within the first few minutes of the film. The whole sequence takes place in an hour.
