4.5.1.6 Drives shall be so designed and so located that they can be cleaned, as indicated in the equipment disassembly procedures. Pulleys shall be so located and protected as to avoid contact with the product. Pulleys shall have sides closed without dead ends.

4.5.1.7 Sprockets in the product zone shall be smooth, solid disks.

4.5.1.8 Conveyors which are an integral part of the equipment and which carry the product through a filling, icing or glazing application shall be readily removable or appropriately fitted for in-place cleaning.

4.5.1.9 The reservoir for the product shall be accessible without dismantling the conveyor.
