Grain Seed Cleaners

Sosnowski Grain Seed Cleaner

Save time, money and frustration with a Sosnowski Grain Seed Cleaner that is user friendly and very simple to operate. Cleaning your own seed will reduce seed, herbicide and transportation costs.  

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

 This is the WS330 model.

The cleaning machines are about as tall as an average size person. Multiple thousands of these grain seed cleaning machines have been sold throughout Europe and other parts of the world and operate without fail.  

The Sosnowski grain cleaning machines are unique because they use centrifugal force for a consistent separating action. A central diffusing element is also key and improves the cleaning quality to almost twice that of most other similar machines on the market. This machine has very few moving parts: just the fan blade attached directly to the motor.  

Unlike the complex process of seed cleaning machines using screens, the operation of the Sosnowski machine is very simple and user friendly with only two controls: air flow and grain flow. These two adjustments determine the cleaning action and provide an infinite number of separations. Their adjustment will depend on what the operator wants to accomplish.  

Controlling the quality of cleaning is different for each grain and sometimes even the same grain from different areas of a field. It all depends on soil fertility and plant health. For this reason, finding the correct screens for a screen machine may vary from year to year or even from different areas of the same field. In screen cleaners, screens need to be removed and cleaned regularly to maintain consistency, even those which feature knockers and ball & rack systems. It is hard to beat the consistency of the Sosnowski machines. 

This cleaner will separate light impurities along with the undesirable light seeds of the crop including seeds infested with fungus. Harmful toxins in grains inhabit more of the cracked kernels and dust. Cleaning your grain will remove a large portion of these undesirables containing toxins and thereby lower toxin levels may be obtained. The chaff, the cracked, the malnourished thins, the diseased lights, along with the smaller/lighter weed seeds are most often what needs to be removed from the good seed. The Sosnowski grain cleaner will accomplish this task with blue ribbon performance. Best of all, it is absolutely user friendly and crazy simple to operate!

One farmer in Saskatchewan had 6,000 bushels of wheat that was contaminated with a high level of Fusarium fungus. It was rated as a grade 3 grain which was unfit for food or feed. The most that he was offered was $2.50/bu. Since the fungus consumes the inner part of the kernel, the thins, the lights, the cracks and the fines are the most susceptible to this infection. After cleaning the grain with a Sosnowski machine, this part of the grain was removed which contained most of the fungus. The grain was then upgraded to grade 1 and the offer on the wheat was $6.60/bu. This price difference was $4.10 per bushel which amounted to an increased value of over $24,000 for the crop.  

The more thorough the desired cleaning, the slower is its rate of efficiency in bushels per hour. If there is a lot of heavy trash in your 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.  

In 2015, we spent over $16,000 to purchase a well known brand of grain seed cleaner that featured four large 42” X 36” screens along with a top aspirator that removed preliminary trash before the seed fell onto the screens. The machine also featured a ball and rack system and a knocker system to help keep the screens clean longer. The screens had to be cleaned frequently anyway. The cracks, the fines, the thins and other foreign material still plugged the holes. Gradually the cleaning action was lost unless the screens were cleaned regularly. A large fan provided a final separation of the light material that was still in the grain. The “cleaned” wheat seed from this screen machine is shown in the picture marked with a “1”.  

If you examine it closely you can see cracked, thin and diseased seeds along with some chaff still in the grain.  

As a test, one ton of this “cleaned” wheat was put through a Sosnowski Grain Seed Cleaner. A hard separation was done. A 100 lb used feed bag was attached to the exhaust to collect the winnowings. The bag was full when the job was finished and can be seen below in the picture marked with an “F”.  

The winnowings were dumped on a pile. This is shown in the picture marked with a “2a” and a closeup is shown in the picture marked with a “2b”.  

There were very few cracks, thin-light or diseased seeds to be found in the cleaned grain after this process. The re-cleaned seed is shown in the picture marked with an “S”.  


Grain Sample

If you send us a sample of your grain, we will run it through a machine and return the results to you. This service is free if you follow these directions:  

1. Send an amount equal to about 2-3 gallons.  

2. Put it into a garbage bag and then into a box.  

3. Include a prepaid return shipping label (that means you pay postage both ways). If you cannot include a prepaid label, include a check equal to the amount of the postage you paid to send it to us.

Purchasing A Cleaner

You don’t need to go break the bank to purchase a Sosnowski grain seed cleaner. This little workhorse packs a lot of punch for a fraction of the cost compared to other cleaners. There is no other grain cleaning machine that gives you more bang for your buck!

Don’t wait to purchase a cleaner until you need it. It is highly likely others will need a machine at the same time and inventory may become a problem. Purchase yours beforehand so you can test it and get it set up to move grain to and from the machine before you actually need it.  

Inventory is stocked for 3 sizes of the Sosnowski cleaners. Larger commercial size models need to be special ordered and are available in 2,600; 4,400; and 9,300 bushel/hour efficiencies.

Made of quality steel construction, the Sosnowski cleaners are run by single phase 110-volt motors. The electrical system is certified to the UL and CSA standards for the U.S. and Canada. Currently there are 18 patents in use for these machines. These machines are manufactured in Poland.

Cleaning efficiency rates are given when the machine is operated at full capacity. Rated capacities will vary with type, size and moisture content of grain. Cleaning performance is acceptable when cleaners are run at full capacity if cleaning grain for feed. To clean grain for seeding, it is recommended to run the grain through at 50% or less of capacity. To clean grain for food, slowing the grain flow rate to a trickle will give you the cleanest seed with the ability to separate out only the largest, healthiest seed.
