Cleaning Crown Bottle- Corks in a Portable Hopper
PORTABLE automatic screener las been invented for cleaning crown bottle-corks and any material of granular or lump form, such as coffee-grain or the like. The illustra- tion shows crown corks being dumped into the device. The corks emerge at the bottom, cleaned of any particles of cork or splinters.
The hopper has a series of zig-zag sloping screens in the interior. The corks roll from these zig-zag screens to a rotating wheel with 1 frame which is radial screen vanes,
