<p>The conveyor is used for weighing and sizing food products such as fruit or root vegetables. It comprises two side frames having a chain or belt running over slidways (3) on their upper surfaces. These carry conical shaped hoppers (2), each one having its side pivoted (1) at the top to form a flap. These are normally held closed by a pin (4) each side and items are synchronised to drop into the hoppers individually. The hoppers then pass over several weighing stations (5, 10) set at various heights. At the correct weight, the pins are released and the item drops down into a receptacle.</p> |
