Fermenter of reactor for zootechnic liquid materials

摘要

A fermenter or reactor for zootechnic liquid materials, comprising a fermentation vessel or container, having positioned therein a movable member for the mixing and stirring of the liquid material. In the reactor or fermenter, said member comprises at least one substantially vertical tube or pipe having windows or slots formed therein as distributed along the length thereof; within said tube or pipe an Archimedean screw is housed and rotatable about its own axis through the action of a drive member.PPSuch a fermenter or reactor is suitable to ensure an accurate mixing of the fermenting mass, while slowly stirring the latter and bringing all of the mass particles in contact with the microbic flora without any disturbance to the fermentation cycle.
