Gravity Separator

A Full Line, to Cover Every Need. Gravity Separators, also known as gravity air tables or density separators, use a combination of air for weighing, vibration for fluidization and conveying and tilt (or slope) for separation. Made for ease of use, longevity and above all, accuracy, Oliver manufacturer equipment like Gravity Separators sort dry, granular, free-flowing material into streams according to particle density. This density separation can effectively separate like-size particles with as little as 0.5% difference in specific density.

Fluidized Bed Dryer

Drying Solutions that Reduce Clumping & Improved Flowability. Oliver Fluidized Bed Dryers prevent product clumping, simplify cleanup and improve finished appearance of seed coatings and treatments while cutting dry time to a fraction. This is a revolutionary solution to the frustrations many processing facilities have for clumping and bridging of treated seed and edibles. The Fluidized Bed Dryer uses a combination of air in motion through a vibrating, tilted table. Seed flow is converted to a “fluidized” suspension, making gentle, uniform drying possible for coated, treated or washed seeds.
