Sanitary drag chain conveyors are typically used for conveying pallets or containers with an irregular bottom board configuration. Drag chain conveyors typically have 2 or 3 strands of roller chain that ride in a carryway, but they are not sanitary. Shown above is a multiple strand plastic modular belt conveyor that serves the same purpose and is built utilizing more sanitary material and design principles.
Drag chain conveyors are not designed for accumulation and should be zoned by means of separate drives where product will accumulate.
