Berlin Grain Feeder   Berlin Grain feeder was developed to allow a proportional high precision mixture of two different products into a production line. The feeder's accuracy is based on the use of load cells, which measure the feed by weight instead of by volume, guaranteeing high precision independent of variations in the product density. High precision (99,5% to the exact weight measured) is also assured by the mechanical and electronic technology used in the feeder and the Software which wasspecially developed for the Berlin grain feeder.
