Winnowers
These machines, some models of which may reach an output of one ton per hour, can
significantly contribute to improving product quality and marketing, especially in
production areas.
Pre-cleaners
These motor-driven devices are generally used to pre-clean grain that has been
harvested when moist, before it goes to the artificial dryer.
There are several models of pre-cleaner:
- The circular pre-cleaner, in which impurities are eliminated principally by suction
(output of about 150 quintals an hour);
- The drum pre-cleaner, in which the heaviest impurities are eliminated by passing
the grain through the meshes of a drum, and the lightest are eliminated by
suction (output of about 10 to 50 tonnes an hour);
- The clodder, in which the bulkiest impurities are eliminated by means of a coarse,
vibrating sieve.
Cleaner-separators
These machines, whose large outputs can be as much as 20 tones an hour, are
certainly the most effective instruments for cleaning grain, and all storage centers
should be equipped with them.
Cleaner-separators are motor-driven and consist mainly of a reception hopper, a fan
and set of vibrating sieves; they clean grain by repeated suction of the lightest
impurities, followed by siftings of the grain.
