The underlying reason why a thermometer is vital lies in its ability to verify that temperatures meet sanitation standards. When dishwashers operate at lower temperatures, pathogens may survive, leading to foodborne illnesses. A thermometer measures water temperature, ensuring it stays within safe ranges.
In commercial dishwashers, the term “sanitizing” refers to the process of reducing the number of microorganisms on surfaces to safe levels. This typically occurs through either high-temperature or chemical sanitization. High-temperature sanitization requires water to reach specific temperatures, whereas chemical sanitization relies on specific concentrations of sanitizing agents, such as chlorine or quaternary ammonium compounds.
The mechanisms involved in dishwashing include the cycle of washing, rinsing, and sanitizing. During the washing phase, detergents break down food residue. The subsequent rinsing removes these residues, and the sanitizing phase requires precise temperature control or chemical concentration to effectively kill pathogens. If any phase underperforms, food safety is compromised.
Conditions that emphasize the need for a thermometer include heavy dish loads, varying types of dishes, or changes in wash cycles. For instance, if a commercial dishwasher is overloaded, water may not circulate properly, preventing certain dishes from reaching the necessary temperature. Regular checks with a thermometer ensure that each load meets sanitation requirements, regardless of variations in conditions.
