Vibrating conveyors. This method uses a solid conveying surface which is turned up on the side to form a trough. They are used extensively in food grade applications where sanitation, washdown, and low maintenance are essential. Vibrating conveyors are also suitable for harsh, very hot, dirty, or corrosive environments. Vibrating conveyors have been built to convey material at angles exceeding 45 degrees from horizontal using special pan shapes
