The appliance is equipped with two different conveyors. The standard conveyor with black seal is suitable for all seeds. The conveyor screw with the red sealing ring is optimised for very small seeds and is therefore particularly suitable for hard, small-grain pressed material. The smaller winding of the red conveyor screw means that less seed is transported. This ensures optimum baling at low temperatures and reduced motor power consumption. With the standard conveyor screw (black seal) you can of course also process small seeds. However, the optimum yield is achieved with the red conveyor screw.
