The revolutionary aerodynamic grain processing technology has many unique capabilities

Each year, in the U.S., a variety of pests and diseases attack corn, wheat, soybeans and other food crops. The problem is that often these factors are spread through the seed supply chain by insects and fungi that can be found in cereal grains.

Unfortunately, it is very difficult to detect the infection until after the harvest has begun because of how widespread these problems are. That's where our machines come in. The all new aerodynamic design of our machines is a radical redesign from the centuries old screen machines. The jet stream of air and aerodynamic principles will automatically separate grain from undesirables with a higher yield success rate than ever before! 

Our multi-purpose machines are capable of processing a wide range of material: Corn, Wheat, Soybeans, Oats, Rape, Rye, Barley, Peas, Maize, Lucerne, Poppy, and all kinds of other grain.

Cleaning, sorting, and grading all types of grain

Prepare uniform seeds for better yields up to 30% or more

High production capacity from 200 to 8000 b/h

Machines will pay for themselves quickly, by adding value to your crop, sometimes after only several hours of use

Separate grain mixtures from multi-species intercropping
