How Many Sinks Do You Need with a Commercial Dishwasher? A Guide for Business Owners.

If you're running a commercial kitchen, you know that having a dishwasher is essential for keeping up with the high volume of dishes that need to be washed on a daily basis. But how many sinks do you need to use a commercial dishwasher effectively? This article will provide all the information you need about the number of sinks required to operate a commercial dishwasher.

While it may seem like a simple question, the answer is not as straightforward as you might think. The number of sinks you need will depend on a variety of factors, including the size of your kitchen, the volume of dishes you need to wash, and the type of dishwasher you have. In this article, we'll explore these factors in more detail and provide you with a comprehensive guide to help you determine the number of sinks you need for your commercial kitchen.

Health Code Regulations

When it comes to commercial dishwashers, health code regulations play a crucial role in determining the number of sinks required. It's important to adhere to these regulations to ensure the safety and well-being of customers and employees.

Local Health Code Regulations

Local health codes may vary depending on the state, city, or county. It's important to check with your local health department to ensure compliance with their regulations. In some cases, local health codes may require additional sinks beyond what national health codes mandate.

For example, in some areas, a separate handwashing sink may be required in addition to the three-compartment sink. This sink must be designated solely for handwashing and cannot be used for any other purpose.

National Health Code Regulations

The FDA Food Code sets the national health code regulations for commercial dishwashers. According to the FDA, a commercial dishwasher must have a three-compartment sink for washing, rinsing, and sanitizing dishes.

The three-compartment sink must be used in a specific order: wash, rinse, and sanitize. The wash sink must be filled with hot, soapy water, the rinse sink must be filled with clean water, and the sanitizing sink must be filled with a sanitizing solution.

The FDA also requires that the water in the sanitized sink must be at a specific temperature to ensure proper sanitation. The temperature must be at least 171°F (77°C) or as specified by the manufacturer's instructions.

It's important to note that these regulations are subject to change and may vary depending on the type of establishment and the state or local health codes. Always check with your local health department to ensure compliance with all regulations.

Size of the Dishwasher

When choosing a commercial dishwasher for your restaurant, it's important to consider the size of the unit. The size of the dishwasher will depend on the size of your kitchen, the number of dishes you need to wash, and the space available for the dishwasher.

As a general rule, for every 100 meals you serve, you will generate approximately 35 racks of dishes to be washed. This means that you will need a dishwasher that can handle the capacity of dishes you need to wash on a daily basis.

A few different types of commercial dishwashers are available, including under-counter dishwashers, door-type dishwashers, and conveyor dishwashers. Undercounter dishwashers are more compact and are appropriate for smaller kitchens or restaurants with fewer table turns. Door-type dishwashers are larger and can handle a higher capacity of dishes. Conveyor dishwashers are the largest and can handle the highest capacity of dishes, making them ideal for larger restaurants or cafeterias.

Manufacturers base the standard measurements for built-in dishwashers on the cabinet opening size. Most standard models will fit a cabinet opening that is 24 inches wide by 24 inches deep by 35 inches high. Some manufacturers offer dishwashers in multiple widths, and there can be slight variations in the depth and height.

It's important to measure the space available in your kitchen before purchasing a dishwasher to ensure that it will fit properly. Also, consider the number of sinks you need to accompany the dishwasher. A three-compartment sink is required in most commercial kitchens for washing, rinsing, and sanitizing dishes. The sink size will depend on the size of the dishes you need to wash and the dishwasher's capacity.

Overall, choosing the right dishwasher size for your restaurant is crucial to ensure that you can efficiently handle the volume of dishes you need to wash daily. Consider the size of your kitchen, the capacity of dishes you need to wash, and the available space for the dishwasher and sinks to make the best decision for your restaurant.

Number of Sinks Required with a Commercial Dishwasher

The One-Sink Rule

According to the International Building Code (IBC), one sink is the minimum requirement for business and mercantile classifications with an occupant load of 15 or fewer. This sink can be used for washing dishes, utensils, and other kitchen equipment. It is also used for handwashing.

The Two-Sink Rule

For larger kitchens, a two-sink rule is often required. One sink is used for washing and the other for rinsing. The sinks should be large enough to accommodate the size of the kitchen equipment being washed. For example, if large pots and pans are frequently washed, the sinks should be large enough to fit them.

The Three-Sink Rule

Some health departments require a three-sink rule for commercial kitchens. This rule is used for washing, rinsing, and sanitizing dishes, utensils, and other kitchen equipment. The three-sink system is also used for washing and sanitizing cutting boards and other food preparation surfaces. Commercial kitchens should always follow the guidelines set by their local health department. It is important to note that the number of sinks required may vary depending on the size of the kitchen, the number of employees, and the type of food being prepared. In addition to the number of sinks required, it is also important to consider the size and placement of the sinks. The sinks should be easily accessible and located in a convenient location for employees. The sinks should also be made of durable materials that can withstand frequent use and cleaning. Overall, the number of sinks required for a commercial kitchen with a dishwasher will depend on several factors. It is important to follow the guidelines set by the local health department to ensure the safety and cleanliness of the kitchen.

Water Source

When it comes to commercial dishwashers, having an adequate water source is crucial. The dishwasher will require a significant amount of water to operate efficiently. It is recommended to have a dedicated water line for the dishwasher to prevent any water pressure issues that could affect the machine's performance. The water line should have a shut-off valve that is easily accessible in case of emergencies.

It is also essential to ensure that the water source meets the necessary requirements for the dishwasher. The water should be at the appropriate temperature, typically between 120-140°F, to ensure proper cleaning and sanitization. If the water is too cold, it can result in poor cleaning performance, while water that is too hot can damage dishes and equipment.

Some commercial dishwashers may require a specific type of water, such as soft water. Soft water is water that has been treated to remove minerals that can cause build-up and damage to the dishwasher. If the water in your area is hard, you may need to install a water softener to ensure your dishwasher operates correctly.

Overall, having a reliable and appropriate water source is crucial for a commercial dishwasher to operate efficiently and effectively. It is recommended to consult with a professional plumber to ensure that your water source meets the necessary requirements for your dishwasher.

Dishwashing Process

When it comes to dishwashing with a commercial dishwasher, it's important to understand the process clearly. The dishwashing process typically involves four main steps: pre-washing, washing, rinsing, and sanitizing. Each step is crucial in ensuring that dishes are properly cleaned and sanitized and that they are safe for use in a commercial kitchen.

Pre-Washing

The pre-washing step is the first step in the dishwashing process. This step involves removing any excess food or debris from the dishes before they are placed in the dishwasher. This can be done by hand or with a pre-rinse spray. It's important to remove as much food and debris as possible during this step, as it can help prevent clogs in the dishwasher and ensure that the dishes are properly cleaned.

Washing

The washing step is where the dishes are cleaned in the dishwasher. This step involves the use of detergent and hot water to remove any remaining food or debris from the dishes. The water temperature is important during this step, as it helps ensure that the dishes are properly cleaned and sanitized. Most commercial dishwashers have a built-in heating element that heats the water to the appropriate temperature.

Rinsing

The rinsing step is where the dishes are rinsed with clean water to remove any remaining detergent or debris. This step is important in ensuring that the dishes are properly cleaned and free of any residue. The rinse water should be hot, and the dishes should be rinsed thoroughly to remove all detergent and debris.

Sanitizing

The sanitizing step is where the dishes are sanitized to kill any remaining bacteria or germs. This step is crucial in ensuring that the dishes are safe for use in a commercial kitchen. The water temperature during this step is important, as it helps ensure that the dishes are properly sanitized. Most commercial dishwashers have a built-in sanitizing cycle that uses hot water to sanitize the dishes.

Maintenance

Regular maintenance is crucial to keep the commercial dishwasher in top-operating condition and ensure it operates optimally. It is important to clean and inspect the dishwasher for damaged or broken parts to minimize future issues. Here are some maintenance tips:

• Check and clean the wash arms regularly to ensure that they are not clogged with debris. Clogged wash arms can affect the cleaning performance of the dishwasher.
• Inspect the spray nozzles and remove any debris or buildup that may affect the water flow.
• Check the door gasket for any signs of wear or damage. Replace it if necessary to prevent water leaks.
• Inspect and clean the filters regularly. Dirty filters can affect the dishwasher's cleaning performance and increase the risk of clogs.
• Clean the interior of the dishwasher regularly to prevent the buildup of food particles and other debris. Use a soft cloth and mild detergent to clean the interior.
• Inspect the hoses and connections for any signs of wear or damage. Replace them if necessary to prevent leaks.
• Check the water temperature regularly to ensure that it meets the manufacturer's specifications.

Following these maintenance tips ensures that your commercial dishwasher operates efficiently and effectively, reducing the risk of breakdowns and extending its lifespan. Regular maintenance can also help you save money in the long run by minimizing repair costs and reducing the need for replacement parts.

Conclusion

When it comes to commercial dishwashers, having the right number of sinks is crucial to ensuring a smooth and efficient operation. Based on industry standards and regulations, a three-compartment sink is typically required in addition to the dishwasher. This sink should be used for manual washing of dishes and utensils that cannot be washed in the dishwasher.

It is also important to consider the size and capacity of the dishwasher when determining the number of sinks needed. As a general rule, for every 100 meals served, approximately 35 racks of dishes will need to be washed. Therefore, it may be necessary to have multiple sinks to accommodate the volume of dishes and utensils being used.

Another factor to consider is the establishment type and the operation's specific needs. For example, a restaurant that specializes in serving wine may require a specialized glass washer in addition to the standard dishwasher. This will help to ensure that glasses are cleaned thoroughly and quickly without the risk of breakage.

In summary, the number of sinks needed with a commercial dishwasher will vary depending on the size and capacity of the dishwasher, the volume of dishes being used, and the establishment's specific needs. By following industry standards and regulations and considering the operation's unique needs, businesses can ensure that their dishwashing process is efficient, effective, and meets all necessary requirements.
