There are plenty of large-capacity products which caterers can adopt, and the 16-1/2” Polypropylene Bread Proofing Bowl (201050) is a generous oblong bowl which has many good points. It measures 16.5” x 5.5” and is a hygienic Polypropylene product which is designed to be able to rise dough products with a minimum amount of effort. Products like this one are dishwasher safe and easy to clean. Bread shops and loaf-makers would find this useful, and it can even be stacked away if cupboard space is limited. Strong and usable with food products, this product is well worth the investment.
