4.34  DESIGN REQUIREMENTS FOR BAKING PANS

4.34.1 Definitions

4.34.1.1 Baking Pan: A container, of single or multiple compartments, designed and constructed for use in the baking of bakery foods.

4.34.1.2 Product Zone: The product zone of baking pans shall include all inside surfaces and those portions of the outside of the pan that may come in contact with the inside surfaces of an identical pan.

4.34.1.3 Reinforcing Member: A separate component added to the basic pan for the purpose of strengthening the individual pan unit.

4.34.1.4 Pan Assembly: Separate individual pan units joined through the attachment of one pan unit to another, or through the use of additional components.

4.34.2 Specific Design Requirements

4.34.2.1 All baking surfaces shall be of a corrosion-resistant material, that is cleanable and coatable with release coatings.

4.34.2.2 All individual components of baking pans shall not have sharp edges.

4.34.2.3 Top rim edges shall be smooth and the bead shall be curled, cleanable and self draining.

4.34.2.4 The corners of the reinforcing members attached to non-product zone of pans or assemblies shall be required to have a radius.

4.34.2.5 Top rim edges constructed with a reinforcing member in the rim should be sealed or provided with a minimum of 1/8 inch (3mm) space between the pans and the reinforcing member.

4.34.2.6 The exterior pan assembly shall not have protruding wires or metal appendages.

4.34.2.7 All welding shall be free of burrs, slag or sharp edges.

4.34.2.8 Exposed welds from wire welding must be of corrosion resistant materials.

4.34.2.9 Reinforcing members should be wrapped with a maximum opening of 1/16 inch (1.5mm) and maximum space (gap) of 1/64 inch (0.4mm) between two materials.

4.34.2.10 Areas of baking pans that tend to trap contaminants shall allow for efficient cleaning and drainage.

4.34.2.11 When notching is required to form corners and the sheet metal is wrapped over non-corrosive resistant materials, the non-corrosive resistant materials shall be totally concealed.

4.34.2.12 All exposed fasteners shall be of corrosion resistant materials.
