Dosing Hoppers: Two large hoppers (bunkers) located at the top are units where material is stored and transferred downwards. Precision Weighing System: The platforms located directly below the hoppers are generally equipped with load cells; this ensures that the product is filled into bags at the determined weight. Pneumatic Control: Pneumatic pistons connected by blue hoses control the flap mechanisms that start and stop the material flow. Filling Spouts: The weighed product is transferred directly into the bags to be packaged (like the red and white bag seen on the right in the visual) through inclined metal pipes. Control Panel: Manual control of the machine is provided by the start/stop buttons (green and red) located on the white stand on the left.
