Patent ID: 7520457

Claim:
A composting system for facilitating a decomposition of organic material, the composting system comprising: a digestion chamber with an input aperture for receiving organic material to be composted, a body portion, and an exhaust aperture for enabling an exhaust of composted organic material from the digestion chamber; an auger shaft with a body portion rotatably retained within the digestion chamber; at least one mixing vane retained relative to the auger shaft for mixing organic material within the digestion chamber; a means for inducing a rotation of the auger shaft; at least first and second divider walls that divide the digestion chamber into at least primary, secondary, and tertiary subchambers wherein the input aperture is in communication with the primary subchamber, wherein the exhaust aperture is in communication with the tertiary subchamber, wherein a first intermediate aperture is disposed in the first divider wall for enabling a passage of organic material from the primary subchamber into the secondary subchamber, and wherein a second intermediate aperture is disposed in the second divider wall for enabling a passage of organic material from the secondary subchamber into the tertiary subchamber wherein the input aperture, the first intermediate aperture, the second intermediate aperture, and the exhaust aperture sequentially decrease in effective height whereby organic material will tend to pass from the primary subchamber into the secondary subchamber, from the secondary subchamber into the tertiary subchamber, and from the tertiary subchamber through the exhaust aperture in response to a rotation of the auger shaft and a concomitant rotation of the at least one mixing vane.
