We designed the filling line for 1-5L and 20L based on dust-free workshop requests, all packaging material including bottle, pail, cartons are all in second floor which will be transited to first floor by gripping type conveyor. The empty pallet outside workshop will be transited to palletize station through pallet feeding conveyor, after palletizing, the full pallet will be delivered to outside to warehouse through pallet conveyor again. All packaging material are all enter worshop from outside to avoid dust come in.
