One of the biggest advantages of "GCS" grain cleaners is that they offer the end user an opportunity to make the system fit their needs. A person with any kind of knowledge about seed cleaning will know that weather conditions (wind, moisture levels, temperature, etc.), state of the crops (wet, dry, damaged, infested or healthy), and resources at hand all impact the seed cleaning process. Depending on the speed of the operation and desired outcome the machines can really be tailored to any specific cleaning scenario.

Below are a few of the most common scenarios that our customers deal with on a regular basis:


Scenario 1

One of the most common applications for the grain cleaner is when a farmer is looking to do some light cleaning of a healthy crop where they are trying to cut off about 5-10% from their original sample. The 5-10% that gets cleaned out will then be fed to livestock for example, and 90-95% of the sample will represent the clean grain that will be used by farmer's discretion. The red mark on the cleaner represents the cut off area between the "clean" and "dirty" grains which can be adjusted by the 5th lever displayed on the exhibit.

Fan speed or air flow can be regulated using a Variable Frequency Drive (VFD) which controls the RPMs on the fan.

Depending on weather conditions, grain type and desired capacity adjustments to the fan speed will need to be made on a case-by-case basis.

Remaining adjustments can be made using the levers on both the front and the back of the machine.

Scenario 2

In cases when a crop is infected with diseases such as vomitoxin or fusarium (scab) harder cut offs during cleaning will be required. In an effort to salvage most of the healthy grains a farmer might need to cut off 30-40% of their sample, however that still enables them to keep the remaining product. The red mark indicates that a much larger section of the cleaner will be capturing the cleaned out sample compared to Scenario 1.

Fan speed or air flow can be regulated using a Variable Frequency Drive (VFD) which controls the RPMs on the fan.

Depending on weather conditions, grain type and desired capacity adjustments to the fan speed will need to be made on a case-by-case basis.

Remaining adjustments can be made using the levers on both the front and the back of the machine.

Scenario 3

Precise cleaning and grading is needed in cases when one is trying to take away the best seeding material. In this situation, all of the levers are in play as we would try and grade the sample and pick out the heaviest kernels that can be used for seeding. As displayed on the exhibit, 3rd lever is the one that will be utilized to separate the heaviest seeds from the rest of the sample.
