Horizontal rotating drum fermentor

Claim 1

A fermentation apparatus comprising; an aseptically sealed, horizontally rotated, cylindrically shaped drum, supported by stiffening rings around the external circumference which bear on external drive wheels or gears, which cause the cylindrical drum to rotate around a horizontal axis, ascepticity of the drum contents assured by a three fluid influent and three fluid effluent connection, said influent connection providing fluid which is to be fermented, removing spent solid materials generated during the fermentation, and providing a heat exchanger fluid, said effluent connection discharging fermented fluid, gases collected above the drum liquid level, and spent heat exchanging fluid, the interior of the drum is provided with two or more parallel mounted fins in a partial spiral configuration to centerline, mounted on interior drum walls in a manner as to connect with the heat exchanging fluid, which enters fins at influent end of drum, and following circulation therein, then exits fins at effluent end of drum, the spiral action of the fins when the drum is rotated moving liquid suspended solids therein to the influent end, cups fastened on the interior surface of the drum which during rotation lift the solids to top of drum, said cups spill the solids to an effluent funnel and discharge pipe, for disposal through influent rotary facility, and or a light source attached to the interior wall of the drum.
