The Sosnowski grain cleaning machines are unique because they use centrifugal force for the separating action. Unlike the complex process of grain cleaning machines using screens, the operation of the Sosnowski [sos NOW ski] machine is very simple and user-friendly with only two controls: air flow and grain flow.

These two adjustments determine the cleaning action. A central diffusing element inside the cleaning tube is also key and improves the cleaning quality to almost twice that of most other similar machines on the market. This machine carries 18 patents and has only one moving part: a fan blade attached directly to the motor shaft.

This machine will clean many types of common grain such as barley, spelt, rye, wheat, oats, maize, corn, soybeans, sunflowers, rape, peas, dry beans, nuts, etc. After cleaning, the grain will be ready for storage, for planting or for grain burning furnaces. The cleaners have also been used for separating the stems and leaves of mint; leaves from frozen fruit; sawdust from wood chips and small bits of wood and plastic from sand and bark.

Solution for Removing Vomitoxin, Aflatoxin and Fusarium

When the motor is engaged on the Sosnowski machine it activates centrifugal force to separate the good seed from dust, chaff, cracks and malnourished light seeds which are often infected with fungus or disease. Harmful fungus and toxins in grains inhabit more of the light or cracked kernels and dust. These diseases can easily double in a month when stored in slightly damp conditions. Separating the good grain from the undesirables will remove a large portion of these toxins.

Separates By Density

The more thorough the desired cleaning, the slower is its rate of efficiency in bushels per hour. If there was a combine problem with a lot of heavy trash in the grain like thistle seed heads, long straw stems, large insects, etc the grain needs to be run through the cleaner slowly to give the cleaner the best chance at separating these heavier items from the grain. The key word here is density. The foreign material may be heavier than your good seed but the cleaner may still be able to separate it if the surface area is large enough. If the density of the foreign material is less than the good seed, very likely it will be separated if the momentum of the grain flow is slow enough so that it isn’t dragged along down with the flow. The company is working on a solution for this problem, and it will be available as an option.

Grading Seed

Field trials have confirmed that using only the healthy, plump seeds for planting may increase yields up to 30%. An added benefit is that the crop may mature more uniformly and up to a week earlier. Grading out the heaviest, healthiest seed can be accomplished by performing a hard separation. This is done by simply increasing the amount of air during the cleaning process. This will cause the lighter seeds that are often malnourished and diseased to exit the exhaust. This material can then be re-cleaned at a softer separation and used for feed or sold.

This same process has been used to sell the best part of the grain crop at a premium because the healthiest, plumpest seeds were the heaviest and had a higher protein content. Grain cleaners can be run at full capacity to remove dockage before storage or burning in furnaces. Cleaning grain for seed a rate of 60% or less of capacity is recommended.

Compact Design

The three stocked models are about the same height as a short, medium and tall size person. These machines can be set up almost anywhere including out in the field to clean grain. They need a level spot to operate correctly but beyond that, the location of their use is not restrictive.

They are not bulky, clumsy pieces of equipment that need large machinery to be moved into place or that need to be mounted in a stationary location. Three anchor rings near the top will expedite the safe movement of the machines from one place to another. Farmers and custom seed cleaning operators alike have mounted these units on small trailers for ease of mobility.

This little workhorse packs a lot of punch for a fraction of the cost compared to other cleaners. Inventory is stocked for the three smallest sizes of the cleaners: 1500, 730 & 330. Model numbers are the capacity of each cleaner in bushels per hour. Motor sizes for the three smallest units are 2hp, 1.5hp, and 1hp respectively. Commercial size models need to be special ordered and are available in 9,300; 4,400; and 2,600 bushel/hour efficiencies.

Sosnowski Cleaning Augers: Small size augers are used to convey seed to the cleaner hopper near the top and take away the good seed from the bottom of the machine. Sosnowski cleaning augers are unique in that they feature fine fluted screws for gentle seed handling and interchangeable screens located along the bottom side of the auger tube. These screens will take out fines and lights as the grain is being moved. Augers are mounted on small wheels making them very easy to move. The 3” augers are sold in 21’ lengths. Augers come in 5’ sections. If the auger needs to be shorter for a specific job they can easily be shortened by eliminating sections.
