Device for transferring solid articles

A transfer device for use vertically between an upper apparatus for carrying out a process and a lower apparatus for carrying out a subsequent process to feed solid articles from the upper apparatus to the lower apparatus by gravity, said transfer device comprising:

• a hollow cylindrical member having an open upper end constituting an article inlet, and an open lower end constituting an article discharge port;
• a solid article guide member fixedly mounted in said hollow cylindrical member and extending from said upper end to said lower end thereof;
• wherein said guide member comprises a central shaft extending along a longitudinal axis of said cylindrical member, and a helical vane mounted about said central shaft and projecting radially outwardly from an outer peripheral surface of said central shaft by a radial distance larger than an outer diameter of said central shaft;
• wherein said cylindrical member is formed of transparent resin;
• wherein said guide member is formed of resin and is integral with said central shaft;
• and
• wherein an iron core is embedded in said central shaft along said longitudinal axis.
