Polem's Easy-flow is designed with a clever adjustment to the funnel shaped part of the silo. This adjustment facilitates the easy outflow of the stored product. This especially applies to single products, which have often been ground. Due to the fibrous and fatty nature of these products, difficulties may be encountered during the outflow of the product. The combination of Polem's Easy-flow and the silo's smooth inner wall facilitates a perfect outflow of the product.
