Question

What are characteristics of a single tank, stationary-rack dishwashing machine with doors?

A) Compact size and manual operation
B) High capacity and automatic operation
C) Portable and energy-efficient
D) Slow cycle time and low water usage

Answer 1

Single tank, stationary-rack dishwashing machines with doors are characterized by high capacity and automatic operation. They are designed for commercial use, where quick, efficient cleaning of large quantities of dishes is needed, and they require special detergents and appropriate loading of dishes.

Step-by-step explanation:

The characteristics of a single tank, stationary-rack dishwashing machine with doors are typically high capacity and automatic operation. These machines are built for efficiency in commercial settings, such as restaurants and hotels, where large quantities of dishes need to be cleaned regularly. Unlike hand dishwashing, which relies on surfactants in detergents to clean dishes, commercial dishwashers use specially designed detergents that work with the machine's cycle to remove food residue and sanitize dishes. Users need to scrape leftover food from dishes and place them correctly inside the dishwasher to ensure all surfaces are exposed to water flow during the cleaning process.

Options like compact size and manual operation, portability and energy efficiency, or slow cycle time and low water usage are less typical of single tank, stationary-rack machines with doors, as these are usually designed to handle a higher workload with quick cycle times and may not prioritize those features.

Answer 2

Stationary-rack dishwashing machines with doors are characterized by their high capacity and automated operation (option B), designed to handle a large volume of dishes with reduced manual intervention. Special detergents are required for optimal cleaning.

Step-by-step explanation:

The characteristics of a single tank, stationary-rack dishwashing machine with doors are related to its design and operation in a kitchen setting. Typically, these dishwashers are characterized by B) High capacity and automatic operation. They are built to accommodate a large number of dishes within a single wash cycle and often incorporate an automated system where the user loads the dishes onto racks, closes the doors, and the machine completes the cleaning cycle without further manual intervention.


It is important to note that when using such dishwashers, the use of a special detergent formulated for machine use is necessary. Users need to scrape off leftover food from the dishes before placing them inside the dishwasher to ensure optimal cleaning and to prevent clogging. The dishes should be arranged so that all surfaces are exposed to the water flow to allow for effective cleaning.
