Walnut weigher is a machine that used in the purpose of calculating in a more realistic way and to ensure production coordination. The product which taken from the upper part of the scale is emptied into the weigher. The weighing is carried out at certain intervals with the aid of the load cell in the weighting pan and results are recorded. The product which was measured is emptied to bottom of the bunker via the pneumatic piston at opening pan. Thanks to the mechanism that is located at the bottom of the bunker product discharging are provided as continuously in the desired amount. In this way, it is possible to quickly calculate the cost and to detect the faultry unit.
