Abstract

The present invention is a lidded vessel containing bacteria on an organic or inorganic matrix, for example, wood chips or ceramic beads, controlled electronically to rotate an internal paddle system on a horizontal axle. When food waste and other organic debris is put into the vessel after opening the lid, a switch senses the lid opening, and as soon as the lid is lowered back into place, the switch contact causes the paddles to rotate the added organic substance into the matrix, covering it for the purpose of coating the waste to prevent odor release, and to bring bacteria into contact with the waste to begin the aerobic breakdown process. Further rotations are timed appropriately when the lid is closed. Sensors determine whether the mass is too wet or too dry. The system is powered electrically. Decomposition can be entire or partial, the latter to encourage compost manufacture, the former to reduce waste output. An output hatch or hatches is provided to withdraw or renew the bacterial matrix charge.

Title: In vessel automatic composter and degrader.

Abstract: The present invention is a lidded vessel containing bacteria on an organic or inorganic matrix, for example, wood chips or ceramic beads, controlled electronically to rotate an internal paddle system on a horizontal axle.  When food waste and other organic debris is put into the vessel after opening the lid, a switch senses the lid opening, and as soon as the lid is lowered back into place, the switch contact causes the paddles to rotate the added organic substance into the matrix, covering it for the purpose of coating the waste to prevent odor release, and to bring bacteria into contact with the waste to begin the aerobic breakdown process.  Further rotations are timed appropriately when the lid is closed.  Sensors determine whether the mass is too wet or too dry.  The system is powered electrically.  Decomposition can be entire or partial, the latter to encourage compost manufacture, the former to reduce waste output.  An output hatch or hatches is provided to withdraw or renew the bacterial matrix charge.

Body: This invention is an in-vessel composter intended for use either inside or outside a building, the purpose of this device being to entirely or partially break down food waste.  This document is divided into paragraphs on internal biology, mixing equipment, electronic controls, and enclosure vessel design.

Inside the vessel, a matrix of either organic matter resistant to degradation, for example, wood chips, or inorganic matter, such as ceramic beads of various design, provides a surface on which bacteria and other microorganisms can thrive.  These bacteria serve to break down food waste and other organic material into ultimately carbon dioxide and water, although the process can be halted intermediately toward the production of soil organic matter "tilth" as a conditioner for the soil.

Inside the vessel is also found a system of paddles on rotating around a...
