Description

Workflow: ● Minimizes time food spends in the Temperature Danger zone ● Minimizes # times food is handled Flooring: ● Smooth ● Durable ● Nonabsorbent ● Easy to clean ● Wear-resistant ● Slip-resistant Porosity: Extent to which a material will absorb liquids Coving: Curved edges of the tiles in the kitchen. It allows for proper cleaning Dry storage temperature: 50 F - 70 F Handwashing station Must be conveniently located.. ● Restrooms / directly next to them ● Food-prep areas ● Service areas ● Dishwashing areas Why is a handwashing station needed near the dishwashing station? When you’re scraping off foods, you cannot put away dried dishes without washing hands because your hands are Contaminated What do you need at hand washing station? Hot/cold running water (100-110 F) Soap A way to dry hands Garbage container Signage NSF (National Sanitation Foundation) labels should be on Equipment NSF Surfaces are.. ● Nonabsorbent ● Smooth ● Corrosion resistant

● Easy to clean ● Durable ● Resistant to damage Common types of Dishwashers ● Single-tank, stationary-rack machine, with doors ● Conveyor machine ● carousel/circular-conveyor machine ● Flight type ● Batch-type, dump ● Recirculating, door-type, non-dump machine 110 F = Water must be this temperature when washing dishes Water must be POTABLE (drinking water) ● Sanitizing solutions ○ Iodine ○ Chlorine ○ Quaternary Ammonia Cutting boards May be wooden or synthetic Wooden cutting boards + baker’s tables must be.. ● Allowed by regulator authority ● Nontoxic ● Made from nonabsorbent hardwood ● Free of cracks and seams Floor mounted equipment MUST be 6” up, or sealed to the floor Tabletop equipment MUST be 4” up Sanitize: Using chemicals or heat to clean up and disinfect at the same time Acid cleaner: A cleaning agent used to remove tarnish, alkaline discoloration, and corrosion from metals. Abrasive cleaner: A cleaning agent which physically scrubs dirt and soil from surfaces. Thermal cleaner: The use of hot water to clean a surface. Cleaning: Removing residue, dirt, grease, and other types of soil from the surface. Detergent: A cleaning agent which removes dirt and grease. Physical cleaning: Scrubbing to clean a surface.

Quaternary Ammonium compounds: common examples of a chemical disinfectant, also known as quats. Solvent: A cleaning agent which dissolves dirt. Chemical cleaning: The use of a cleaning agent to clean a surface....
