Composting apparatus

摘要

Composting apparatus comprises a plurality of containers (D) for receiving and processing organic waste. Each container receives air through a supply manifold (Ms) and vents gases into an exhaust manifold (Me). The apparatus includes a variable speed blower (A) for blowing air into the supply manifold, and means for measuring pressure differences between the manifolds and means (C) for adjusting the blower speed in response to the detected pressure difference.
