Once the wash is finished, the water is drained, more hot water enters the tub via an electromechanical solenoid and the rinse cycle begins. Once the rinse cycle is finished and the water has drained, the dishes are dried using one of several drying methods. Typically, a rinse aid, a chemical to reduce the surface tension of water, is used to remove water stains from dishes and glasses that do not have streaks resulting from water hardness or other reasons. In addition to domestic units, industrial dishwashers are available for use in commercial establishments such as hotels and restaurants, where a large number of dishes need to be cleaned. Washing is carried out at temperatures of 64–70°C (148–159°F) and sanitization is achieved through the use of a superheater providing a “final rinse” temperature of 80°C (178°F) or through the use of a chemical disinfectant. Undercounter dishwasher: For small businesses like diners, bars or churches, an undercounter dishwasher is a good choice. They are small and compact, taking up the same space as a residential dishwasher, but can still process up to 35 racks per hour. These dishwashers may have a door, but carousel-type undercounter glasswashers are also available. These types of dishwashers work well in establishments that serve fewer than 100 meals per hour, such as small restaurants or bars. Single and Double Door Dishwashers: Door dishwashers are just what they sound like. They generally stand upright and the washing compartment has one or two doors on the sides for loading and unloading the dish baskets. Inside, the wash arms clean the dishes. They are available with high temperature options or low temperature chemical sanitization options. Conveyor Dishwasher: Just like they sound, these dishwashers feature conveyor belts that run through the machine to carry baskets under fixed spray arms to be washed, rinsed and sanitized. Many models, such as the Noble Ware wash conveyor series, are available with high-temperature hot water sanitization or low-temperature chemical sanitization options and can handle over 200 baskets per hour. Flying dishwashers: These machines must be custom built for each establishment and can vary widely in both design and capacity. With this type of machine you don't even need dishwasher baskets as all the dishes are placed directly on the conveyor belt and dragged through the machine. Belt machines are ideal for large facilities such as university canteens, banquet halls or hospitals. Dishwashing chemicals When working with low temperature machines, it is essential to use dishwashing chemicals to ensure adequate cleaning at everyusage. These chemicals allow your commercial dishwasher to sanitize and clean dishes at temperatures that will not naturally sanitize your dishes. When purchasing the right chemicals, you should look for a chemical that works with both your dishwashing systems and the dishes you are cleaning. For example, some commercial dishwashing units can only accept powder, liquid, or solid detergent, and some metal products are made of materials that wear out after washing because they require a metal-safe detergent. While there are multiple brands to choose from, Noble Chemical provides some of the most effective and affordable commercial dishwasher chemicals in the industry, helping to reduce costs while keeping your business ahead of the curve. For every 100 meals served, you will generate approximately 35 dish racks to wash. This varies by restaurant type, as the number of dishes used by each guest and the number of times a table is turned over in a day changes when considering casual versus fine dining. If your restaurant is a refined establishment, the number of table shifts will be lower, but the number of dishes per guest will be higher. Quick-service restaurants, on the other hand, have more table turns per day but use fewer dishes per guest. Make sure your dishwasher can handle even the largest crowd. Backing up during peak hours can cause quite a few headaches, so make sure you take the time to choose the right machine to handle even the busiest days. Add approximately 10-20% extra capacity to account for business growth during peak hours. dishwasher life. These dishwashers have a lifespan of 5 to 10 years if maintained properly, and hopefully your business will grow significantly over the course of those 5 to 10 years. Also take into account the dishes in the kitchen, not just the dining room. Forgetting about pots and pans can spell disaster for your dishwashing schedule. Make sure your dishwasher can handle the dishes from all your guests as well as the dirty pots and pans generated by your employees.

Dishes of your perfectly executed creations are delivered to eagerly awaiting customers. Glasses of wine and mixed drinks are enjoyed by all. Yep, it's every restaurateur's dream until, UH-OH, your commercial dishwasher decides to stop working. That dream is now your worst nightmare come true. So what can you do to prevent a commercial dishwasher failure? Like all commercial equipment, proper maintenance will improve its performance and extend the life expectancy of the machines. Keep in mind that a well-maintained dishwasher will last up to 20 years. Below are several maintenance steps you can take to take care of your commercial dishwasher. Read the owner's manual: Before cleaning, maintaining, or servicing any equipment, always read the provided owner's manual or search for it online. Pre-Scrappage Procedure: Even the best commercial dishwasher is not a food disposal. Make sure your employees carefully remove food debris before placing it in the dishwasher. Otherwise, the filter will become clogged. Clean the filter: Check the filter regularly. If you see food particles and dirt on the filter, the water flow will be blocked causing your dishes to not clean properly. A clogged filter will also prevent drainage.
