De-awner is used for pre-treatment of various grain types; the purpose of the de-awning operation means is to remove the awns from barley kernels, loose husks from wheat, and to clip oat kernels.
The de-awning process is usually carried out immediately after the crop has been harvested, the grain is fed with an air/screen cleaner in order to remove the loosened awns.
In a modern rice mill, de-awning is an important process before husking operation to eliminate awns of the paddy grains for easy conveying in the elevators, chutes, and hopper orifices.
Because of the awns, it cannot be processed mechanically as the seeds club with each other and makes the processing difficult by restricting the flow of material during processing.
The clipper/de-awner can be used where heavy de-awning is required but also for products where only a light de-awning is needed.
For de-awning of barley, breaking up clusters of beet seed and for surface polishing of grains and vegetable seeds, thereby improving appearance and increasing bushel weight.
