Inspection of jars and bottles is an essential part of any reliable bottle filling operation. Beverage bottles need to be inspected for foreign objects, contaminants, or any residual liquid before filling. After filling, the bottles need to be checked again to ensure the desired fill level, no leaks or potential label problems. Bottles generally travel along conveyors that feed them into the system whereby non-contact optical inspection takes place. This process is usually automated and uses technology to scan the bottles for any potential issues. Considerations for selecting bottle inspection equipment include the size, shape, and material of the bottles, production speed, and the relevant inspection parameters. Bottle inspection equipment is widely used in the food industry to ensure compliance with quality control procedures as well verification.
