最上部に設けられるノズルから槽外に抜き出される。The operation of the present invention having the above configuration is as follows. The granular material supplied from the inlet nozzle (6) rolls on the slope of the inverted funnel-shaped washing rack (2) installed at the top of the washing tank, descends radially outward, and then descends. Falls on the outer peripheral portion of the slope of the funnel-shaped trough-shaped washing rack (3) having a large opening diameter, and then descends inward in the radial direction while rolling on the slope. The granules then fall from the narrow part of the funnel-shaped shelf to the top of the slope of the lower inverted funnel-shaped shelf. The granules move to the bottom of the cleaning tank while repeating the descending motion in sequence and are delivered to the next step by the extracting means (11) through the outlet nozzle (8). During this time, the granular material rolls on the slope of the washing rack and makes good contact with the slope and the cleaning liquid, so that the adhered liquid adhering to the surface of the granular material is separated and removed. When the adhered liquid separated on the washing rack is insoluble in the washing liquid and has a low specific gravity, a part of it moves inward in the radial direction along the lower surface of the inverted funnel-shaped washing rack, and the narrow mouth is closed. After that, it rises in the center of the tank and reaches the liquid level. The remaining adhering liquid moves radially outward along the lower surface of the funnel-shaped shelf, reaches the gap between the outer periphery of the shelf and the tank wall, and rises along the tank wall to reach the liquid surface. To do. As described above, the adhered liquid reaching the liquid surface becomes a tank and is drawn out of the tank through a nozzle provided at the top of the tank wall.
付着液が洗浄液に溶解する場合は、槽底部の出口ノズル
から粒状体とともに抜出し手段により槽外に抜き出され
別設の装置で処理される。When the adhering liquid dissolves in the cleaning liquid, it is taken out of the tank together with the granular material from the outlet nozzle at the bottom of the tank by the extracting means and is processed in a separate device.

る。As can be seen from the above description, since the granular material only moves downward while rolling on the slope of the washing rack, it is possible to obtain an effect that the granular material is not damaged or deformed. In addition, the adhered liquid separated from the granular material is insoluble in the cleaning liquid and does not come into contact with the granular material again when the specific gravity is low, so that a high cleaning effect can be obtained.
