Abstract
Device for trimming aristate seeds comprising a vertical spout wherein the seeds to be trimmed travel by gravity counter to a light air flow passing through one of the alveolate plates of a conveyer. In the flow-orientated position, the seeds are housed in one of the alveoli of the plate to be presented in this position to a trimming station comprised for example of a horizontal gas ramp positioned transversally to the direction in which the conveyer is translated.
Claims5
A device for trimming grains each having a caryopsis and an awn projecting therefrom, comprising:
- a substantially vertical channel member having a lower portion and an upper portion, said upper portion receiving said grains which fall freely into said upper portion without exact orientation;
- a conveyor positioned below the lower portion of said channel member for movement in a substantially horizontal plane, said conveyor including a plurality of spaced essentially vertically oriented elements and a substantially horizontal netting located below and transverse to said elements, said elements and netting defining a plurality of cavities;
- blowing means for blowing a current of air upward into the lower portion of said channel, said current of air orienting said falling grains with their awns projecting generally vertically upward, said grains falling into the cavities in said conveyor with their caryopsises contained within said cavities and supported on said netting, the awns projecting vertically upward from said cavities;
- and
- trimming means positioned adjacent to and above said conveyor downstream from the lower portion of said channel member, said trimming means destroying the awns transported thereto by said conveyor without damaging the caryopsises.
