Care of bottle pool in breweries
The NRW pool seems to be in need of attention, this was evidenced in investigations and calculations into the degree of scuffing. This contribution contains proposals for effectively improving conveying of bottles in filling plants and gives limit values for chemical stress in bottle washers. A method for analysing weak points in a bottling plant in terms of mechanical stress on bottles is also presented. This method developed at the Faculty of Brewing Equipment and Food Packaging Technology provides every brewery with a tool to evaluate in-house filling plants.
Scuffing is damage to the surface of bottles, resulting from a combination of mechanical and chemical influences on a returnable glass bottle (Fig. 1). 2). Approximately 2.3 million bottles were checked.
