1	Redesign and Development of HotRot1811 Composting Unit and Ancillary Item Harris, Daniel January 2012 (has links) This project investigated alternative materials, methods and processes to reduce manufacturing costs while improving the marketability and performance of the HotRot1811 compost machine. Some of the redesign aspects include investigating alternative insulation materials, corrosion within the vessel, stress and strain gauge testing of the shaft and tines, and alternative design considerations. Another aspect of the project is to test and develop a compost classifier. The compost classifier is used for separating contaminants from compost which could be an alternative technology HotRot Organic Solutions Ltd may produce. This report describes the findings, recommendations and conclusions of these investigations. Design redeign development compost machine corrosion strain gauge organic material HotRot
