BIO-REACTOR Russian patent published in 2011 - IPC C12M1/04 

FIELD: machine building.

SUBSTANCE: bio-reactor consists of case with branches for supply of processed bio-mass (source substrate), for drainage of finished fertiliser, and for withdrawal of bio-gas, of circulation pipe positioned in centre of case and of uniformly perforated pipe in form of vertical spiral located under circulation pipe. Turns of spiral of the perforated pipe form a cone with its base up. Diametre of an upper turn of the spiral is equal to internal diametre of the circulation pipe and is located at the level of a lower cut of this pipe. The circulation pipe is made in form of a cylinder reservoir consisting of two pipes of different diametre, space between which is filled with heated water for bio-mass heating. The branches for supply of bio-mass and drainage of finished fertiliser are arranged on opposite sides of the case, also, the supply branch is set in an upper section of the case, while the drainage branch - in a lower one.

EFFECT: raised efficiency, stability and completeness of bio-chemical processes in bio-reactor due to uniform bio-mass mixing and distribution of temperature through whole volume of bio-reactor.
