ALS grain cleaners advantages. Dimensions

The most important parameter that ensures productivity is the width of the separation chamber. The wider the separation chamber – the wider the separators hopper is, and the wider the hopper – the wider the grain layer is. A wider layer of grain provides a bigger grain pouring to the separation chamber and, accordingly, productivity. Sure, you can increase the pouring by increasing the thickness of the grain layer from the hopper, but in this case you can forget about the quality of separation. A more powerful fan will also not save you, because the collision of seeds in a thick layer happens too often, and the separation becomes a chaotic process.


The wing impeller alone is not suitable for use in cleaning devices. It produces a stream that is heterogeneous in cross-section and very turbulent, the air moves progressively, rotatingly and swirls – turbulence appears. Whereas our ALS separators have a very effective aerodynamic system thanks to a special straightening device (straightener) developed by our engineers. It is installed directly after the impeller and eliminates all the above-mentioned drawbacks of the wing impeller itself. The presence of a straightener in our separators increases the precision of grain separation by 20-30% compared to separators with only the rotor and fan.

Light fraction catcher ULF

New device! We have developed and produced additional equipment for the ALS aerodynamic separators – light fraction catcher (ULF). The main function of the new device is to catch and hold light impurities from the air stream coming out of the separator.

Description of grain cleaner ALS-7

ALS-7 is a grain cleaning machine of new generation intended for cleaning and calibration of any grain, grain legumes, melons and gourds, vegetable and herbal crops, as well as all kinds of granular mixtures. The separator shows high efficiency when working with the following cultures: wheat, corn, oats, flax, barley, rye, millet, sorghum, peas, soya, beans, lentil, buckwheat, rape, mustard, sunflower, coffee beans.

There are 4 modes of grain processing in ALS-7 separators:

  • Preliminary grain cleaning;
  • Primary grain cleaning;
  • Seed calibration (grain sorting);
  • mixed mode (simultaneous cleaning and calibration).

The main advantages of ALS-7 are mobility and ability to work from the usual socket of 220 V. It is easy to move it around the warehouse, as it is equipped with wheels and its weight is only 100 kg. Loading in a separator is made by worm wheel, pneumatic or tape loaders. Grain from fractions as a rule is taken away through pipes in acceptance supply bins or any other tanks. Also, there are clips for bags completed with separator.

This grain separator is ideal for use in small farms with the area under crops up to 300 hectares.
