A modular nut cleaning plant comprises a nut sizer and a stick remover mounted to the nut sizer. A vacuum unit is mounted to the stick remover. A nut product stream will pass on the stick remover through the vacuum unit which will vacuum light debris from the nut product stream. The nut product stream moves on a chain on the stick remover. Large debris and sticks that do not fall through openings in the chain will pass into a debris conveyor. Nuts and debris that fall through the openings in the chain will be delivered to the nut sizer. The nut sizer will rotate and tumble nuts and debris in the nut product stream. Nuts of an undesirable size and debris will pass into a debris conveyor. Nuts of a desired size will pass through the nut sizer into a chute or other conveyance to be delivered to further nut processing apparatus.
