4 Types of Commercial Dishwashers

Commercial kitchens are a bustling space. Time is precious, and washing dishes can be a time-consuming chore. That is where commercial dishwashers come in handy. Not only do they save time, but with advancements in technology, they can also be more water-efficient than trying to do everything by hand.

When considering buying a commercial dishwasher, it is essential to understand the various types available. This allows for better decision-making before making a purchase. But it is not just the equipment alone that is important. It also matters where you buy the equipment from.

Types of Commercial Equipment for Dishwashing

Commercial dishwashers can be broken down into four different types: under-counter dishwashers, stationary single-tank doors, single-tank conveyors, and multiple-tank conveyors. Each type has its unique energy requirements and functions. Each is built to fit different needs and kitchen setups, and understanding the distinctions between these types can help you determine which machine is best for you when selecting a dishwasher for your commercial kitchen.

Under-Counter Dishwashers

An under-counter dishwasher is a more compact appliance. The typical height of this type of machine is 38 inches or less. Under-counter dishwashers efficiently clean dishes by running them through a sequence of wash and rinse sprays. These machines are also great for smaller spaces, as they are designed to fit conveniently under kitchen countertops.

Under-counter dishwashers can come with both chemical and hot water sanitizing options. The hot water sanitizing option comes with an internal booster heater. Only these machines that are designed for wash cycles of ten minutes or less can qualify for Energy Star.

Stationary Single-Tank Door Dishwashers

A stationary rack, single-tank, door-type dishwasher is a machine where a rack of dishes remains stationary while undergoing a cycle of wash and rinse sprays. Other variations of the machine may also have racks that revolve on an axis during the wash and rinse cycles.

Some subtypes of this category include:

  • SingleWashTank
  • MultipleWashTank
  • DoubleRack
  • Pot, Pan, and Utensil Washers
  • ChemicalDumpType
  • HoodedWashCompartments (also known as "hood type")

These dishwashers can be either chemical or hot water sanitizing, also featuring an internal or external booster heater for hot water sanitizing.

Single-Tank Conveyor Dishwasher

A single-tank conveyor dishwasher is a ware washing machine that uses a conveyor or similar mechanism to move dishes as they go through their cycles of wash and rinse sprays inside the machine. These machines feature a tank for wash water, followed by a final sanitizing rinse. They do not include a pumped rinse tank.

Sometimes this type of dishwasher will also include a pre-washing section before the main washing section. Single-tank conveyor dishwashers can operate using either chemical or hot water sanitizing methods. Hot water sanitizing is often equipped with an internal or external booster heater.

Multiple-Tank Conveyor Dishwashers

A multiple-tank conveyor dishwasher is another conveyor-type machine. These machines contain one or more tanks for wash water and one or more tanks for pumped rinse water, followed by a final sanitizing rinse.

Multiple-tank conveyor dishwashers may also feature one or more pre-washing sections before the main washing phase. These dishwashers can operate using either chemical or hot water sanitizing methods, with the latter often featuring an internal or external booster heater.

Technology in Commercial Equipment for Dishwashing

Commercial dishwashers may also come with some advanced technology features depending on the type and model. This technology is designed to create a more effective and efficient wash cycle. Some of these features may include soil sensors, upgraded jets, upgraded filtration, and unique dish rack designs.

Soil Sensors

Soil sensors use technology to detect how dirty the dishes are as the wash cycle is happening and adjust the cycle to make sure the load is sufficiently cleaned. They also make these adjustments to ensure minimum use of water and energy.

Upgraded Jets

Some machines now offer jets that are specifically designed to use less energy as they spray detergent and water over the dishes during cycles.

Upgraded Filtration

Improved filtration systems remove food particles from the water used for the cycles to allow for more efficient use of detergent and water. Additionally, the last rinse of clean water allows for cleaner dishes to come out of the cycle.

Unique Dish Rack Design

Unique dish rack designs may allow for maximum effectiveness for cleaning dishes as they more strategically lay out the dishes during cycles.

Sustainable Commercial Equipment Choices

Commercial dishwashers are known to be one of the biggest consumers of water and energy within commercial kitchens. They can often make up more than two-thirds of the total water use within the commercial kitchen space. The life expectancy of a commercial dishwasher is 20 to 25 years, with high-efficiency units offering greater potential for substantial energy and water use savings.

Commercial dishwashers typically have a tank that heats water between 110°F to 140°F. High-temperature machines need an extra booster water heater to ensure the rinse water reaches above 180°F for sanitization. Reducing rinse water usage not only conserves water but also offers substantial energy-saving potential. The efficiency of these dishwashers is measured in gallons per rack, influenced by factors like water consumption, wash cycle duration, and load time.

When buying a commercial dishwasher, make sure to choose to buy from a place that has sustainable and environmentally friendly standards in mind. It will not only be better for the environment but also can save you money in the long run.
