The UCT9's patented central aeration tube allows maximum oxygen flow into the chamber while also assisting with moisture control. Oxygen is crucial to the tumbler's speed and efficiency because aerobic (oxygen breathing) bacteria work far faster than other microbes. The UCT9 also features a patented break-up bar and baffles to aid in the mixing process. Working in combination, these features help ensure that materials are thoroughly mixed in the tumbler, thus effectively preventing "balling up" and ensuring high quality, useable composting in a matter of weeks rather than months.
