The PIZETA rotary cleaner sieves the raw material, to remove any foreign bodies or grain sizes that don’t meet the required parameters. The product is transported by the auger to a drum where a rotating whisk with a special profile centrifuges the product around the entire surface of the flexible mesh. The resulting final product is passed through the sieve, while the waste is piped out of the machine. The stainless steel drum is easy to replace and can be supplied in perforated sheet steel or mesh. The sieve mesh size depends on the capacity and type of product to sieve.
