ABSTRACT:
A vial washer in which the vials follow a serpentine path through several stages of cleaning. A sheet having the serpentine path in the form of an elongated slot guides the vials through their washing. Conveyor belts moving in opposite directions underneath the elongated slot move the vials in the directions through the equipment. The conveyor belts have an open grid allow for the passage of the cleaning liquids through them. The sheet with the cut-out slot may be replaced with a similar sheet with a different width of opening for bottles of differing sizes. The cleaning may include one or more stages of a detergent wash, water rinse, and air and vacuum drying. Slight deviations in the straight sections of the elongated slot will cause the vials to rotate so that all sides become clean. Using a sheet with an appropriately shaped elongated slot and reversing the directions of some of the conveyor belts changes the number of straight path segments and thus the length of the overall path of the vials through the equipment. The adjacent belts may have slightly different speeds, with the higher speeds at the beginning of the path, to force the vials towards each other where they may support each other in an upright position. Cleaning the bottles involves passing them along the predetermined path having the straight segments connected by curved sections.
