PURPOSE:To decrease the height of a boiling tank and obtain a compact apparatus by arranging plural heat-radiation pipes on concentric cylindrical surface around the shaft of a screw conveyor. CONSTITUTION:The bottoms 24, 26 of boiling tanks 8, 10 have semicircular cross-sections. A partition plate 28 is placed and screwconveyors 12, 13 are arranged in parallel. Plural heatradiation pipes 32, 34, 36, 38 are arranged interposing spacers 40, 41, 42, 43 on a concentric cylindrical surface around the shaft of the screw conveyor. |
