4  SPECIFIC PRINCIPLES TO COVER EXCEPTIONS AND ADDITIONS TO THE DESIGN, CONSTRUCTION AND CLEANING OF ALL BAKERY EQUIPMENT, AS DEFINED IN SECTION 3.

4.17  DESIGN REQUIREMENTS FOR PAN GREASERS

4.17.1 Specific Design Requirements

4.17.1.1 The reservoir for pan grease shall be readily accessible and so constructed as to drain completely. If a valve is used, it shall be of a sanitary take-apart design at least equal to the 3-A Standard for valves, and shall be readily accessible for cleaning.

4.17.1.2 Heating elements inside grease reservoirs shall be smooth, corrosion-resistant, and readily removable. Heating elements on the outside of the grease reservoir shall be sealed or mounted in such a manner as to be removable.

4.17.1.3 Openings for the introduction of pan grease into the reservoir shall be of such design as to prevent spillage and contamination of materials by contact with non-product zone surfaces. Such openings shall have a raised rim at least 3/8 inch (10mm) . Where an exterior opening is provided for filling, a suitable cover shall be provided which shall be readily removable.

4.17.1.4 Pumps shall be of a sanitary take-apart design equal to the 3-A Standards 02, 04, and 44 for pumps, and shall be readily accessible for cleaning.

4.17.1.5 Spray heads, nozzles, or disks shall be removable. Disks with non-smooth surfaces shall be permitted where the practical function so requires.

4.17.1.6 All lines carrying pan grease shall be readily removable and readily accessible.

4.17.1.7 Screens, filters, or other equipment used for the removal of crumbs or foreign particles shall be constructed of corrosion-resistant materials. They shall be readily accessible and readily removable for cleaning. Screens shall be constructed of perforated material.

4.17.1.8 Pan conveyors shall be designed to preclude contamination of all pan surfaces by dirt, carbonized particles, and other foreign material.

4.17.1.9 All oil reservoirs shall be designed to prevent contamination.

4.17.1.10 All internal and external framework, bumpers, guides, tracks or supports attached to ceiling or walls shall be sealed at the point of contact. Hollow supports and braces shall be sealed. Equipment resting on floors or pads shall be supported on sanitary legs or shall be sealed to the floor.
