The interface between a moving conveyor belt and a work piece can be
lubricated using an air driven stream of finely divided droplets of a
lubricant composition. Droplets of a preferred size are directed by the
air stream onto the conveyor with little waste of lubricant off the
conveyor. The lubricant provides a very low coefficient of friction and
little or no stress cracking in the containers. Using a low pressure and
low flow rate air stream in conjunction with a low flow rate liquid
lubricant attains the useful particle size in the lubricant add on spray.
The liquid lubricant is sheared by the effect of the air flow creating the
desirable droplet size and pattern of lubricant on the conveyor. A food
container conveyor device having improved lubricant properties can be
lubricated using a lubricant composition that can become ingested by a
user from a food or a container for the food, can come into incidental
contact or direct content with a food composition, can be incorporated at
measurable concentrations into the food, or can be used generally on food
conveyor surfaces wherein the food is exposed to the lubricant.
