Step-by-step explanation:
The primary purpose of dish washing equipment is to clean dishes effectively and efficiently. Whether it's hand dishwashing or using a dishwasher, the equipment should be designed and installed in a way that allows the water, detergent, and surfactants to effectively remove food particles, grease, and stains from the dishes. This ensures that the dishes are not only visually clean but also free from any residue that could affect the taste of the food.
