NOVELTY - Organic refuse is added to or as base material to stir tanks (11,12). Wet-bulb temperature of material, moisture content in various regions during hot air blowing are calculated, and material temperature are all detected. A heat gain necessary to correct the difference between calculated and detected value is calculated. Hot blast temperature and amount of hot air are controlled, and organic refuse is thus composted.    USE - For composting the organic refuse.    ADVANTAGE - The organic refuse is crushed and stirred uniformly and reliably with simple composting apparatus by accelerating fermentation of base material.    DETAILED DESCRIPTION - Organic refuse is added to the base material or as base material to the stir tanks of horizontal-type process machine (10). The wet-bulb temperature of base material, moisture content in pre-heating period, constant drying rate period and falling drying rate period are calculated at different time course during hot air blowing, and base material temperature are all detected. A heat gain necessary to correct the difference between calculated and detected value is calculated. A hot blast temperature and amount of hot air are controlled and organic refuse is composted.    An INDEPENDENT CLAIM is included for the organic refuse composting equipment, which comprises several stir tanks, and hot air supply apparatus (30). The stir tanks has stirrers (13,14) with stirring blades (13B,14B) attached with rotation axis (13A,13B) which extends horizontally. The apparatus (30) is connected to the stir tanks for supplying hot air to the apertures (17,18) in the stir tanks at a position less than deposition surface of the base material. The organic refuse was added or blown into the stir tank.    DESCRIPTION OF DRAWING(S) - The figure shows the block diagram of organic refuse composting apparatus.
