Title: Refuse and thickened slurry conversion to compost - in chamber with oxygenous gas flow through revolving arms
IPC: C05F7/00
Filed: 1974-11-12
Abstract: Refuse and thickened slurry is converted into compost by continuous passage through a chamber in a gas flow which promotes the biological transformation. This gas is introduced by perforated gas distributor arms which revolve around an axis parallel to the material motion. The desired path is enforced by extracting the gas at several places in the side wall of the chamber. The excellent aeration results in very uniform treatment so that the residence time the treatment is greatly reduced. The total power requirements of this system are lower than those of conventional systems.
