Patent DE-4309430-A1 (DE)
Title: Method and device for sorting fluffy materials which can be transported by air
Inventor: JUNGBAUER LEOPOLD
IPC: B07B11/04
Filed: 1993-03-24
Abstract: The invention relates to a method and device for sorting materials which can be transported in an air flow, such as bed feathers, down, fibres and the like, according to the precharacterising clause of the patent claim. The material to be sorted is classified in the sorting device according to the invention in a vertically upwardly flowing air flow by exploiting the different fall rates of material particles of different size and weight. The speed of the air flow, which carries the material upwards, is predetermined by the cross-sectional distribution of the sorting device. The classification of the material being sorted can be adjusted individually in each chamber for material being sorted. As no uncontrollable flow processes (flow separation, backflow regions) can occur in the sorting device according to the invention, classification of the material to be sorted can be accelerated considerably in relation to known methods. Moreover, the sorting device requires less construction space in relation to known methods.
