Sprouting beans refining method

Abstract

Sprouting beans refining apparatus is provided wherein refuse matters of hulls, trashes, small roots, etc. are removed of sprouting beans efficiently. Sprouting beans raked up by raking-up conveyor 1 are caused to fall down on endless flat belt 6 which is supported by vibration frame 3 inclinedly upwardly toward moving direction. Sprouting beans on the endless flat belt are sent downwardly by vibration of the vibration frame 3 to fall down on lower endless flat belt 6. Refuse matters of roots, trashes, etc. contained in the sprouting beans attach to surface of the endless flat belt 6 and are transferred together with the endless flat belt 6 to be removed off by scraper 12. Refined sprouting beans are discharged from lower end of the endless flat belt 6 of lowermost stage.

What is claimed is:  
     
         1 . A sprouting beans refining apparatus comprising; a vibration frame for supporting an endless flat belt, of which surface is easily wettable by water, inclinedly so as to make a moving direction thereof upward; a drive unit for driving said endless flat belt toward said moving direction; a vibration generator for giving said vibration frame vibration in a reverse direction of said moving direction of the endless flat belt so that sprouting beans on said endless flat belt are sent toward said reverse direction of the moving direction of the belt; and a scraper disposed opposingly to said endless flat belt for removing attachments to said belt.  
     
     
         2 . A sprouting beans refining apparatus as claimed in    claim 1   , wherein said endless belts, each being supported by said vibration frame and comprising said vibration generator and said scraper, are arranged in series in two or more stages.  
     
     
         3 . A sprouting beans refining apparatus as claimed in    claim 1   , wherein said endless belts, each being supported by said vibration frame and comprising said vibration generator and said scraper, are arranged in series in two or more stages in a state of upward and downward directional lamination.
