Sosnowski Grain Seed Cleaner
Clean your own seed and save time, money and frustration. Increase the value of your crop. Cleaning your own seed will also reduce seed, herbicide and transportation costs. With a Sosnowski Grain Seed Cleaner, that task will be very simple. These machines are extremely user friendly to operate.
This machine will clean many types of common seed 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 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 machines have been sold throughout Europe and other parts of the world and operate without fail.
Constructed of quality steel and galvanized, the Sosnowski grain cleaners are manufactured in Poland and powered by single phase 110-volt electric motors certified to the UL and CSA standards for the U.S. and Canada. Currently there are 18 patents in use for this machine.
These 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 a wide range 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 grain cleaners.
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 of the cracks and thins will remove a large portion of these toxins. 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. This conventional grain cleaner also featured a ball and rack system plus 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, or light 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”.
Seed Cleaner Operation
To begin a seed cleaning operation with a Sosnowski machine, set the grain flow control at the 1/2 position and the air flow control to the completely open position for corn and beans, at the 3/4 open position for wheat and rye, and for oats, it's at the 1/2 open position. Turn the machine on. Pour a small amount of grain into the hopper. Examine the winnowings that exited through the exhaust and the good grain that fell down through the center tube.
Adjust the air flow and grain flow controls and repeat this process until you are satisfied with how the grain is being separated.
Increasing the air flow will remove more winnowings. Decreasing it will remove less.
Once this adjustment is set satisfactorily, begin a continuous grain flow. Continue to monitor the separating process and make minor adjustments as needed. A larger grain flow may need a bit more air flow to obtain the same results.
