Rinsers are used in a variety of ways, but the most significant use is in a filling line (bottled water, beer, sodas, salad dressing, or other edible or drinkable products). When used in a filling line, they are placed just prior to the filler to rinse the container prior to being filled. The two types used are wet and dry rinsers. Wet rinsers use water and possibly another media. There will be a twist at the infeed end of the rinser to invert the bottle where jets can shoot into the container to remove dust and debris.
Upon exiting the rinser, the container will go through another spiral to turn it right side up. A dry rinser will use air to remove the dust and debris, and some have vacuum systems. A Gripper Rinser is one of the most common dry rinsers used.
