WS Grain Cleaners

Multiple thousands of these Sosnowski grain cleaning machines are in use today. They are made of quality components and operate for many years without fail. One company bought a cleaning machine in 2013 to separate plastics. It was used 24/7 for two years non-stop including holidays and weekends. The third year it ran 12 hours a day, five days a week. It has operated with no down time during that time period.

WS Grain Cleaners

Separates By Density Using Unique Air Flows

The WS Sosnowski [sos NOW ski] grain cleaning machines use unique air flows created by centrifugal force to separate good grain from almost any crop material. Seed cleaning using air flow is gentle. The air flow adjustment determines the cleaning action and its proper control is key to obtaining good results. A central diffusing element and a unique pattern of seed spreaders is also key. With the excellent design of the Sosnowski grain cleaner, grain cleaning quality is improved to almost twice that of most other similar machines on the market.

Regulating the air flow controls the separating action. Air is sucked up through the center tube in a unique pattern and exits out the exhaust. Anything less dense (weight and surface area) than the good grain will exit the machine through the exhaust. Even material that is heavier than the good seed may be taken out if its surface area is large enough. For example, wheat heads can be taken out even though they are heavier than the good seed because its surface area is much larger.

 

Cleans Various Grains

The WS machines will clean many types of common grains such as barley, beans, corn, durum, hemp, lentils, maize, oats, peas, poppy, rape, rye, soybeans, spelt, sunflower, wheat and many more. After cleaning, the grain will be ready for storage, for planting or for grain burning furnaces. These cleaners have also been used for separating leaves from frozen fruit; sawdust from wood chips and small bits of wood and plastic from sand or bark.

Solution For Disease In Grain

Quality standards vary for cleaning grain depending on its end use. Harmful fungus and toxins such as vomitoxin, aflatoxin, fusarium and ergot is harbored mostly in the chaff, the light seeds and the cracked kernels. These diseases can easily double in a month when stored in slightly damp conditions. Removing this part from the good grain will lower the infection rate. The air flow through the grain will help dry down a high moisture crop. Cleaning tests with popcorn and spelt were conducted and the results tested by a certified lab. The popcorn was infested with a vomitoxin level of 11.2 which is unusually high. The spelt tested at 1.5 vomitoxin. After being cleaned with one of our grain cleaners, the popcorn tested at 1.8 and the spelt tested at 0.7.

Small Investment, Short Payback

It is easy to increase the value of your crop such as one farmer did in Saskatchewan. In 2016, he 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 WS machine, this part of the grain was removed which contained most of the fungus. The grain was then upgraded to a 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. His Return On Investment (ROI) was short and his purchase added more profit to his bottom line.

Grading Seed Adds Value

Field trials have confirmed that using only the healthy, plump seeds for planting may increase yields up to 30% more. 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. Increasing the air flow will cause the lighter seeds, which are often the malnourished or diseased seeds to be separated from the healthiest, plumpest seeds having the highest test weight. Premium prices can be obtained for high value grain. The other separations can be used for feed or sold as a lower grade grain.

Consistent, Efficient, User Friendly

​Because these machines have no screens to clean, it’s hard to beat their consistency and efficiency. The settings on these machines can be changed very quickly, even for different crops. Grain cleaning machines using screens are often slow and complex to operate which was best accomplished by a professional custom grain cleaning operator. Choosing the correct screens is a continuous process because the kernel size of grain may vary from year to year or even from different areas of the same field in the same year. This variation is caused by differences in weather, soil fertility and plant health. Screens must be cleaned regularly to maintain consistency and becomes an ongoing, arduous task. Cleaning your own grain for seed like a pro is now possible for the average Joe. Best of all, these machines are very user friendly and crazy simple to operate!

Compact, Durable & Maintenance Free Design

These machines can be set up almost anywhere. This can reduce seed, herbicide and transportation costs saving you time, money and frustration. Their footprint is small. They can be integrated permanently into grain handling systems. Mounting them on small trailers or on a frame with castors will keep the unit mobile.

The fan is mounted directly on the motor and is the only moving part on the machine. There are no lubrication points and no spare parts are needed.

Some operators who already own a good screen machine will purchase a WS grain cleaning machine and set it up to pre-clean grain before it runs through a screen machine for the sole purpose of speeding up the cleaning process. Much time is saved when screens don’t need to be cleaned as often.

Straight Exhaust
The straight exhaust is used to blow the tailings out on the ground rather than collecting them in some sort of vessel. It can be installed on the Sosnowski grain cleaner instead of the standard exhaust assembly. The cleaning process becomes more efficient by avoiding down time to change the collection vessels. This is convenient for those who have large quantities of grain to clean.

WS  Scalper 

Using just an aerodynamic grain cleaner such as the WS Sosnowski for removing disease or dockage from grain may be sufficient. The minimum standards for cleaning grain for food or for planting through an air seeder may be much higher. 

 

A grain cleaner using screens separates by size and will usually have two screens. The top one will scalp off the large trash and the bottom one will sift out the fines. A major problem with these type of grain cleaners is that the process is not only slow and tedious but the bottom screens need to be cleaned frequently or the cleaning action will soon be lost.

Because the Sosnowski grain cleaners use only air to clean grain, the foreign material that is more dense (weight & surface area) than the good seed will not be separated from the grain. A WS Scalper is needed to finish the job of removing the largest and heaviest trash. 

 

The most efficient setup of the Sosnowski grain cleaner and scalper is to run grain through the cleaner first and then through the scalper. With a Sosnowski grain cleaner mounted directly on top of the scalper, grain drops out the bottom of the cleaner and onto the screen where the remainder of the largest foreign particles will be scalped from the grain. This will optimize and streamline the action of the equipment. This setup is much more efficient than using just a screen machine.

The angle of the scalper box is adjustable to help regulate the flow of grain across the screen. The height of the discharge is sufficient enough (varies with the angle of the shaker box, about 16” to 24”) so an auger may be used to collect the clean grain.

Since the density of split seeds of soybeans, lentils and peas are almost identical to the whole seeds, the Sosnowski grain cleaner will only remove some of them (about half in our experience). A second screen can be added to the shaker box on the scalper to sift out these splits.

The scalper is powered by a farm duty 110/220 volt, 1/2 hp motor and comes with one screen suitable to scalp wheat and rye. Additional screens are readily available and can be matched with your crop. See the setup page on this website for more details on the shaker box.

Filter Fabric
The filter fabric on the exhaust assembly allows air to escape while containing the tailings. One is included with each new machine. They will last a good while with proper care. Dirty ones can be machine washed. Purchase one to keep as a spare or as a replacement.

Award Winning Performance

The inventor, which also manufactures these machines has won numerous awards including a gold medal at the 50th World Exhibition of Innovation, Research and New Technology Eureka in 2002 and a silver medal at the 51st World Exhibition of Innovation, Research and New Technology Eureka in 2003 in Brussels Belgium, a bronze medal in Jena - Nurmberg Germany in November 2006, in Geneva Switzerland in April 2007 and a distinction in Canada's Farm Progress Show in 2015. This machine carries a total of 18 patents.
