GEBR. Ruberg - Model Series RV and RVS -Aspirators

11 graduated throughput levels from 40 t/h to 300 t/h are available. Wind sifters and separators can be used in recirculation and exhaust air modes respectively. The numerous RUBERG Aspirator versions and options are ideal for integrating into existing and new systems.Fitted with proven sieve combinations, they can reliably clean cereals, rape, leguminous plants, oilseeds, seeds, nuts, coffee, millet, rice, spices and other products.

When sorting products such as malting barley, malt or seeds, clear fractionation is achieved together with high throughput due to especially large sieve areas. We keep a wide range of the various performance categories and also accessories and service available for you.We also deal with the interface to plant engineering and further peripherals for you.

The product to be cleaned passes through one or more inlet pipes into the air part’s large pre-distributor. Together with the feed flap, the polygon effect of the feed roll guides a pre-defined product stream on to the entire width of the machine. The product falls freely over a metal cascade through a rising stream of air. The air volume and speed are set either manually or automatically so that light particles such as dust, spelt, pieces of straw, shrivelled grains etc. are carried upwards by the air stream. In the integrated expansion chamber the particles drop out again at a lower air speed and are discharged to the side by a screw conveyor. In recirculation mode, the air is accelerated by internal fans and returned to the vertical air sifter as part of the cycle (see the more detailed description under slider air recirculation mode). In exhaust air mode, particles are fed with the entire air into external filters and separated there. From the vertical air sifter the fruit now falls on to the sieving decks. It is guided across coarse, grain and sand sieves which are fitted across the entire width of the machine. The product is fed on to the slightly inclined sieves by the circular oscillating movement of the entire sieve deck. The product distributor and guide plates ensure optimum use of the available sieve surface.

Up to four fractions can be separated in one cycle. The RVS series achieves constantly high cleaning quality performance with optional deflector flaps. Sieves do not have to be changed when changing the fruit from e.g. rape to barley. There is no reduction in throughput due to the option of manual or automatic switching. The additional “Multi” designation indicates that there are further deflector flaps located between the vertical air sifter and the sieve assembly (machine upper and lower part). The product stream is divided again here and guided to the upper and lower sieve decks. By fitting different sieves it is possible to clean different types of fruit without changing the sieves.
