Abstract

One of the best ways for recycling is the Producing of vermicompost from municipal waste. Worms optimal separation of organic material after finishing process increases the rate of decomposition of waste by composting worms placed.To design and build a system for induction heating the substrate in a controlled vermicompost fertilizer which leads to separation worms from bed and does not get hurt, the thermal parameters manure vermicompost is the essential. The method of mixtures and hot wire as a heating source was used for measuring the specific heat and thermal conductivity of vermicompost, respectively. The measurements were done at 40, 50, 60 and 70ºC temperature levels and 20, 30, 40 and 50% (w.b) moisture content levels. The specific heat of vermicompost increased from 1.6537 to 3.5236 kj/kg°C, with increase in the experimental temperature and moisture content levels. The thermal conductivity of vermicompost increased from 0.1054 to 0.9163 wm-1°C, with increase the temperature and moisture content.
