- This is a design for a winnowing machine capable of cleaning any of
the seed commonly used in bird keeping I have been using it on parrot seed machine with
great success. mine has a plastic front which makes adjustments very easy. It can easily
be put together using any suitable material.
- Front and back are made from any ply or hardboard, better still the
front can be made clear plastic this will allow you to see winnower in operation. the
internal struts can be made from any wood or ply as long as they are thick enough to take
the screws. Any domestic vacuum cleaner will do the job. Very little if any should go into
the vacuum cleaner they should all collect in the bottom of the winnower.
- The seed and husks are fed into the top, it usually necessary to stir
it with your fingers to maintain a flow when the winnowing the larger seed such as sun
flower. The lighter husks are drawn into the chamber inside the winnowing and the clean
seed falls straight through and is collected in a container on the floor
