The most modern technology is the result of generations of experience. Use our expertise in the field of preliminary and main cleaning of cereals, oilseeds, leguminous plants, malt, coffee, etc. 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, mil-let, 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. 5Method of OperationThe 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 on page 6).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 pos-sible to clean different types of fruit without changing the sieves.6Design VariantsRUBERG Aspiratorin the air recirculation mode This operating mode represents the most commonly used mode for cleaning cereals. The product to be cleaned enters the large air part’s pre-distri-butor through one or more feed pipes. Together with the dosing flap, the polygon effect of the feed roll guides a pre-defined pro-duct stream across the entire width of the machine. The pro-duct falls freely over a metal cascade through a rising air stream. The air volume and speed are set either manually or automati-cally so that light particles such as dust, spelts, pieces of straw, shrivelled grains etc. are carried to the top by the air stream. In the integrated expansion chamber the particles drop out again at low air speed and are discharged to the side by a screw con-veyor. In the air recirculation mode the air is accelerated by inter-nal fans and fed back to the vertical air sifter.RUBERG Aspiratorin the exhaust air modeIn some areas, increasing environmental influences cause higher concentrations of mycotoxins, remains of toxic metabolism products which may occur especially during warm and humid weather during the period in which rye and wheat bloom. Exhaust air is a reliable means of avoiding recontamination when cleaning such types of fruit. These machines are mainly characterised by the air vent in the vertical air sifter. This allows 100% fresh air to be fed in and the air laden with dust and particles is taken up by an external nozzle filter. All RUBERG Aspirators and vertical outlet sifters can be sup-plied for exhaust air operation. 7Design VariantsRUBERG Air AspiratorsThis type is exclusively used for air-related cleaning work. Infeeds and infeed distributors guide the product into the pre-distributor. The polygon effect of the feed roll together with the feed flap feeds a thin coating over the sheet metal cascade. The product coating is streamed through rising air. Dust and light particles are picked up and carried to the expansion chamber, fed through guide plates. Here, the air speed decreases, large particles drop out and are transported out of the machine at the side by a screw conveyor. Further on, the air reaches the blower separator. Here, dust and fine particles are fed outside and separated into an external nozzle filter with a small amount of exhaust air. The remaining air is re-accelerated by “inline” fans in the blower chamber and fed back into circulation. RUBERG Air AspiratorsThese are driven by either recirculation air or exhaust air and are also available with an extensive range of accessories. RUBERG Sieve SectionThis design is especially suitable for products which have already been pre-cleaned or those which have a low proportion of dust or light particles. The RUBERG Sieve Section stands out especially for its qualitatively and quantitatively good sorting performance. A circular rotating sieve section is suspended by flexible rods within a frame. An infeed funnel fitted to the frame which reso-nates in harmony with the frame feeds the product on to the sieve deck. The product is fed across the entire width of the machine, for example over coarse grain sieves, grain sieves and sand sieves. The slightly inclined sand sieves are supplied by the circular oscillating movements of the entire sieve stack. The product distributor and guide plates ensure optimum use of the available sieving surface. This means that up to four fractions can be sorted in one cycle. RUBERG Sieve Sections are available in performance classes from 20 t/h to 300 t/h and with an extensive range of accesso-ries. 8RUBERG RV 40 – RV 60 AspiratorsScheme of operationRUBERG RV 40 - RV 60 series AspiratorsA powerful “cereals cleaner”, compact in design and fully develo-ped for throughputs of up to 60 t/h.It is fitted with 2 coarse grain sieves and 4 grain sieves.

It is fitted with 4 to 8 especially large coarse grain sieves, 6 to 20 sand sieves and 6 to 20 grain sieves. Since the smallest particles are removed early via the sand sieves the grain sieve sorting performance is especially high. As from the RVS 180 MULTI series, two sieve assemblies work in parallel and achieve an unbeatably high sorting performance due to their extremely large sieving area. By moving the sorting selection flaps the upper sieve assembly can be run at 50% throughput, the lower sieve assembly at 50% throughput or both sieve assemblies together at 100% throughput capacity. This makes cleaning a series of fruit types possible without changing sieves. Change-over flaps on the machine base permit numerous combinations of additional fractionings with-out a sieve change, as the fruit is brought together again in sub-com-partments. All grain fruit types and also rape, maize, peas, beans etc. can be cleaned here. Light particles and dust are separated out in the upper part, the vertical air sifter.

Adjustment of the air quantity determines the particle size to be separated. Opti-mum setting of the wind quantity is possible by means of visual checks directly at the machine. The air flap is controlled by an electrically driven servo motor and is part of the basic equip-ment for all RUBERG Aspirators.Infeed regulatorDepending on the back pressure, a pre-defined product stream is fed to the sheet metal cascade from the vertical air sifter’s pre-distributor. The feed flap pressure load depends on the type of fruit and is adjustable by changing the lever arms. Infeed automation (patented)For optimum performance distribution, the product fill level in the pre-distributor should vary between the minimum and maximum values. With changing fruit types and fluctuating infeed quantities, automatic adjustment of the feed flap pressure is recommended. RUBERG infeed automation performs this adjustment at any time, regardless of the fruit type and its consistency. It prevents backing up in the infeeds, prevents operating errors and optimi-ses the cleaning quality. The air quantity adjustment device controls the air flap servo drive. Fitted in the central switch room, it works in parallel with the operating panel on the machine. This permits quick remote adjustment. The digital display values are allocated to the corres ponding fruit types and deliver precisely reproducible results. The air quantity adjustment device with the operating panel on the machine is part of the basic equipment for all RUBERG Aspirators.Electro-pneumatic adjustment of the 3 flapsManual adjustment of the 3 flapsPatented grain infeed controlChange-over flaps RUBERG Aspirators have various change-over flaps depending on their capacity and flexibility. By setting switches outside the machine they serve to control internal product routing. The change-over flaps are available with manual operation or with manual operation and position indicators or with fully automa-tic adjustment units.15Exhaust air cleaningEnvironmental requirements and also operational and process engineering tasks are examples for the requirements pertaining to the treat-ment of RUBERG Aspirator exhaust air.
