The item in question is most likely a dishwasher used in industrial settings to sanitize dishes using high temperatures and chemical sanitizers like chlorine, ensuring reduction of microbes to public health-safe levels.
The item described in the question seems to be a dishwasher used in industries like food service, where high levels of cleanliness and sanitization are required. Dishwashers utilize very hot water, often at 160 degrees Fahrenheit or above, along with chemical sanitizers, such as chlorine, to sanitize the dishes.
This process is aimed at reducing the microbial load to levels that are considered safe for public health. While sterilization is the complete eradication of all microbes, sanitization does not guarantee the complete removal of all microbial life but rather a reduction to safe levels. Besides dishwashers, other methods of microbial control include the application of chemical disinfectants on surfaces, heat treatment of food and water, and the use of antibiotics for treating bacterial infections in humans.
