This presentation will examine the typical glass quality issues that the brewing industry faces, and how to remove the defective bottles before they are filled and sent to market. There are numerous defects that have been identified by the glass industry as requiring detection and removal from the production stream. The glass manufacturing process may have inspection technology to remove these defects, but data from plants using inspection technology indicate that there are still many defects that end up at the brewery. Empty bottle inspection is more recently being used to perform the inspection of new glass in one-way markets such as the United States. As the quality of new glass varies, end users must use technology to ensure that the glass for their particular product is of the highest quality and defect free. The returnable bottling plant also inspects for defects in the bottle that are caused by normal wear in the bottle’s life cycle, such as thread damage or scuffing, and these are discussed as well. Empty bottle inspection (EBI) systems in the beer industry typically perform inspection of the finish, body/sidewall and base. Other inspections, as well as integrated bottle sorting, are normally standard for returnable glass breweries. EBI technology relies on vision technology, with detection of contrast differences being the key indicator. This is a reliable means of detecting most defects such as chips, stones, blisters, cracks, bird swings, etc. The brewer must be able to write a specification for detection of quality issues, and this discussion will assist you in how to do that. Some defects (such as unfilled shoulder) can be easily detected, but are difficult to write a detection specification for. These will be identified, and a reasonable approach will be discussed.
