Ensuring your crops are cleaned thoroughly is a hugely important part to getting your grains ready for consumption or commercial use: ensuring grains and seeds are adequately clean means lower risk of bacteria growth.

Our equipment handles a wide range of grains, peas and seeds including: wheat, barley, oats, maize, rice, sorghum, vegetable and oil seeds as well as many others. We’ve got you covered, from initial advice on all aspects of processing, to individual machines, design, and the supply and installation of complete plants.

The cleaners are available with 2, 3 and 4 cleaning/grading sections in two possible diameters and they are fitted with easily interchangeable screens allowing different solutions and capacities in each individual section for any crops. A range of Aspirators complements the cleaning system, removing dust and light trashes prior to the cleaning.

How it Works

The flow of product through the aspirator is regulated by the positioning of the hinged feed control flap which, aided by the feed roll, creates a thin stream of falling product in the aspiration chamber in which light trash is removed by the powerful aspiration effect. Heavier lifted trash is collected in the settling chamber and discharged by screw unloader.

Inside the rotary cleaner the grain can be scalped, cleaned, graded, have small weed seeds screened and cleaned grain screened and graded by size. The tailings and other trashes are expelled through the Tailings output. Each screen has an independent output where ducts can be fitted to collect the product.
