Ruberg

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.

This operating mode represents the most commonly used mode for cleaning cereals. The product to be cleaned enters the large air part’s pre-distributor through one or more feed pipes.

In 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.

This 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.

This 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 “high-performance cereals cleaner”, compact in design and fully developed for throughputs of up to 60 t/h. It is fitted with 1 espe-cially large coarse grain sieve, 4 grain sieves and 2 sand sieves. All grain fruit types and also rape, maize, peas, beans etc. can be clea-ned here. Light particles and dust are separated out in the upper part, the vertical air sifter. Fractioning into coarse grains, granules and small grains takes place in the sieve section. By means of built-in change-over flaps the machine can, for example, be run without changing sieves and without losing performance when loaded with barley and rape. The performance when cleaning rape is almost as high as with heavy cereals.

A “high-performance cereals cleaner”, compact in design and fully developed for throughputs of up to 100 t/h. It is fitted with 2 espe-cially large coarse grain sieves, 4 to 5 sand sieves and 4 to 5 grain sieves. The grain sieve sorting performance is especially high since the smallest particles are removed early via the sand sieves. Change-over flaps on the machine base permit numerous combinations of additional fractionings without a sieve change, as the fruit is brought together again in sub-compartments. 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. Frac-tioning into coarse grains, granules and small grains takes place in the sieve assembly. By means of built-in change-over flaps the machine can, for example, be run without changing sieves and with-out losing performance when loaded with barley and rape. The performance when cleaning rape is almost as high as with heavy cereals. .

A “high-performance cereals cleaner”, compact in design and fully developed for throughputs of up to 300 t/h. It is fitted with 4 or 8 especially large coarse grain sieves respectively, 6 to 20 sand sieves and 6 to 20 grain sieves. The grain sieve sorting performance is especially high since the smallest particles are removed early via the sand sieves. From the RVS 180 series upwards, two sieve assemblies work in parallel and achieve an unbeatably high sorting perfor-mance due to their extremely large sieving area. Change-over flaps on the machine base permit numerous combinations of additional fractionings without a sieve change, as the fruit is brought together again in sub-compartments. 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. Fractioning into coarse grains, granules and small grains takes place in the sieve assembly. By means of built-in change-over flaps the machine can, for example, be run without changing sieves and without losing performance when loaded with barley and rape. The performance when cleaning rape is almost as high as with heavy cereals.

A “cereals cleaner with maximum efficiencies”, compact in design and fully developed for throughputs of up to 300 t/h. 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. Fractioning into coarse grains, granu-les, small grains and extra-fine grains takes place in the sieve assembly.

The amount of air circulating in the vertical air sifter is controlled by an air flap in the blower chamber. Adjustment of the air quantity determines the particle size to be separated. Optimum 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 equipment for all RUBERG Aspirators.

Depending 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.

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 optimises 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.

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.
