What Is a Commercial Dishwasher and How Does It Work?

It is a high-performance dish washing machine suitable for commercial occasions, such as restaurants, hotels, cafés, bakeries, catering businesses, hospitals, schools and other industrial kitchens. Commercial dishwashers are designed for washing large numbers of plates, glasses, serving trays, pans, cutlery and kitchen utensils rapidly, hygienically and consistently far more than a domestic dishwasher in your home. Washing dishes in a commercial kitchen is time-consuming, labour-intensive and almost impossible to manage during busy service periods. Commercial dishwashers aid in saving cleaning time, maintaining hygiene standards, controlling water usage & ensuring the kitchen workflow. Regardless of whether you have a small café, fast-food outlet, hotel kitchen, or large catering operation the kind of commercial dishwasher you choose can have a direct impact on your speed of service, staff efficiency and hygiene levels throughout your kitchen. What Is a Commercial Dishwasher? A commercial dishwasher is an industrial-sized machine specifically designed to wash large quantities of dishes quickly in a professional restaurant kitchen. It incorporates high-pressure water jets, timed washing cycles, detergent, rinse aid and hot water to scrub kitchenware clean of food residue, grease, stains and bacteria. They are mainly used for cleaning commercial dishwashers. Plates and bowls Glasses and cups Cutlery Serving trays Cooking utensils Pans and kitchen tools Food preparation containers The commercial dishwasher is primarily used for rapid and hygienic washing of items while being able to accomplish a load 10 times the amount of a standard domestic sized dishwasher. This is especially important for restaurants and hotels, as they need to keep plenty of clean dishes ready at your disposal all day long. A slow dishwashing system can also create a bottleneck in the kitchen, affecting timing, table service and customers’ experience. What Is the Working Principle of a Commercial Dishwasher? Commercial dishwashers work through a professional washing process. Commercial dishwashers generally mimic a similar cleaning cycle; the actual system can vary by model. Pre-Rinsing Staff typically scrape residual food waste and rinse plates or cutlery before loading items into the dishwasher. Doing this ensures that no big chunks of food enter the machine and blocks the drainage. It is particularly important because the pre rinsee will enhance washing outcomes, and also enhance the performance of dealing with greasy stains from sauces as well as oils, starches & dried food sediments. Loading the Dishwasher Rack Dishes, cups or glasses, forks or spoons (or knives), placed in the appropriate racks of a dishwasher. This is important because water jets are expected to reach all surfaces. Like placing plates upright, secure placement of glasses and arrangement of cutlery (so that each object can be cleaned by water). Main Wash Cycle It sprays hot water mixed with detergent over the items during the wash cycle. The water power cleans grease, food scraps, and stains. Most commercial machines are configured to go fast. Because many models can finish a cycle in less time than it takes to run a home dishwasher, they are an ideal choice for busy kitchens where you need dishes reused quickly. Rinse Cycle Clean hot water is used to rinse the items off once they are finished washing. Rinse aid can also be used to help water run off the surface more smoothly and reduce water marks, particularly on glasses and stainless-steel items. The rinse or wash cycles are important from hygiene and appearance aspects. Clean dishes make a better impression on the customers in hotels, restaurants and cafés. Drying and Unloading Some commercial dishwashers have a drying assist, whereas others simply utilize the heat from the rinse cycle to help things dry faster. When the cycle completes, staff unloads clean dishes to be reused. Good workflow around loading/unloading is very important. The dishwashing area in a commercial kitchen should be designed so dirty items enter from one side and clean items exit the other traffic flow routing to avoid cross-contamination. Commercial Dishwasher vs Domestic Dishwasher Plenty of owners ask us whether they can run a domestic dishwasher in their small café or food business. The short answer is that a domestic dishwasher was not built for the demands of a commercial kitchen. A commercial dishwasher is different because it is designed for: Faster washing cycles Higher daily usage Stronger cleaning performance Better hygiene control Heavy-duty stainless-steel construction Larger washing capacity Professional kitchen workflow Easier maintenance in business environments While these domestic dishwashers may suffice for household purposes, they are generally too slow and too light-duty for restaurants, cafes, hotels, bakers kitchens and catering kitchens. Types of Commercial Dishwashers Not all commercial dishwashers are created equal, and your right type really will depend on the size of your kitchen, washing volume, space available, and what you are washing. Undercounter Commercial Dishwasher An undercounter commercial dishwasher is a machine that can fit neatly underneath the counter. This is ideal for low-volume kitchens in small cafés, bars, and coffee shops. This type is typically a good fit for smaller commercial dishwasher applications, where space is at a premium and restaurant-quality performance is still needed. Best for: Small cafés Coffee shops Bars Small restaurants Limited kitchen spaces Hood Type Commercial Dishwasher However if looking for equipment designed for medium to high volume kitchen operations, a hood type or pass-through dishwasher will work great. A rack of dishes is loaded by staff and a hood lowered before initiating the wash cycle. This is a common type used at restaurants and hotels as it provides a precise working flow and this type can hold more dishes in comparison to undercounter types. Best for: Restaurants Hotels Catering kitchens Busy cafés Medium-sized commercial kitchens Conveyor Dishwasher A conveyor dishwasher is basically made for extremely high volume operations. Movement through the machine is on racks or trays via a conveyor system, which makes it ideal for large kitchens that need non-stop washing. Best for: Large hotels Hospitals Universities Canteens Large catering businesses Glasswasher A glasswasher is made for glasses, cups and barware only. It is used in bars, cafés, restaurants, hotels and coffee shops. Best for: Bars Coffee shops Cafés Restaurants Hotel lounges Benefits of Commercial Dishwasher Commercial dishwashers provide many uses to professional kitchens. Faster Cleaning One of the major advantages: speed Unlike a domestic dishwasher or using a manual wash, A commercial dishwasher does not only wash large batches of dishes but much faster too. It also assists businesses in streamlining their lunch rush, dinner service, banquets and catering events. Better Hygiene Commercial kitchens need to maintain the expected hygiene standards. A commercial dishwasher removes grease, leftovers and bacteria considerably more effectively than hand washing. There are several things that help keep your kitchen cleaner and more sanitary such as hot water, detergent to remove grease and grime, rinse cycles AND proper equipment design. Lower Labour Pressure Thanks to them, manual dishwashing is time-consuming and staff-consuming. By investing in an industrial dishwasher, the strain on labour is lessened and kitchen staff can focus their efforts on preparing food to serve or performing cleaning tasks that require the human touch. Consistent Results Hand washing results differ from person to person, especially in a busy kitchen. In contrast, a commercial dishwasher has more consistency because the machine is programmed to run through a cycle each time. Improved Kitchen Workflow Dirty Clutter MovesYou around a dishwashing area well planned OutOors into clean movements. This reduces delays, crowding and confusion during peak service hours. Professional Presentation A customer feels pampered when the plates, glasses and cutlery are clean. Presentation is equally as important to hygiene for hotels, restaurants and cafés. How Much Water Does a Dishwasher Consume? It is also worth noting that consumption varies according to the type, size, model and washing cycle of the appliance. A commercial dishwasher is for handling heavy loads with maximum efficiency, and many contemporary models are engineered to incur minimum water and energy losses. The important question, in a commercial kitchen, is after how much water a dishwasher utilizes though what really matters regarding these machines is not simply how much water they use per cycle but water-use per rack or even water-use-per-number of dishes cleaned. Depending on how it is used, a commercial dishwasher can certainly contribute to reducing water waste as opposed to constant manual washing when best practice in loading and pre rinsing are followed by staff. Businesses should use the following checks to regulate water usage: Water usage per cycle Energy efficiency Wash cycle length Rack capacity Rinse system design Staff loading habits Maintenance condition When it comes to restaurants, hotels and catering kitchens picking the right size machine is crucial. An under-size machine will require far too many cycles, whilst an oversized machine may waste energy and space. Cleaning a Commercial Dishwasher Cleaning a dishwasher is basic for sanitation, execution and the future of the machine. It is necessary because if you do not maintain and clean your commercial dishwasher regularly, grease, food particles, detergent residues and limescale can accumulate. Basic cleaning steps include: Remove Food Waste After the service, clear the large food debris found in the dishwasher interior, filters and drain area. the Filters Filters trap food remnants, and have to be washed frequently. Clogged filters may decrease washing efficiency (it can also lead to drainage problems). Wipe the Interior Wipe down the inside surfaces, the door area and seals and corners where dirt can build up using a clean cloth. Check Spray Arms Spray arms should rotate freely. Clogs will block holes, water pressure becomes weak, and dishes are not cleaned. Use the Correct Detergent Always use commercial grade dishwasher detergent and rinse aid. It can damage the machine and deteriorate cleaning quality, if not used properly. Descale When Needed Limescale can form inside of the dishwasher in hard water areas. Descaling on a regular basis will also reduce the possibilities of damaging your heating, spray system, and internal parts. Whether a dishwasher is spotless works more efficiently, consumes less energy, and minimizes the risk of unpleasant odors or poor washing results. Common Problem: Dishwasher Not Draining Domestic and commercial machine problems such as a dishwasher not draining are the most common. Commercial kitchen drainage issues can easily bring kitchen operations to a halt, so any problem should be addressed immediately. Common causes include: Blocked filters Food waste in the drain area Clogged drain hose Grease build-up Faulty drain pump Incorrect installation Poor cleaning routine To prevent drainage issues, staff should scrape down food waste prior to loading, clean filters each day and check the condition of the drain area on a regular basis. An experienced commercial appliance technician should be called to inspect the machine if the need for a commercial dishwasher repair has developed after basic cleaning of dishwasher drains, as continued failure to drain could result in damage to other components of the machine and loss of kitchen time. Small Commercial Dishwasher: Is it worth it? Compact dishwashers can prove useful for limited space businesses or lower wash volume kitchens. However, if you will be using a dishwasher in a business kitchen make sure it is not a domestic model but rather a small commercial dishwasher. A compact commercial dishwasher might be ideal for people: Small cafés Coffee shops Juice bars Small restaurants Office pantries Food kiosks Small bakery shops Before buying, consider: The daily number of dishes you clean per hour Available kitchen space Type of items being washed Water and electrical connection Drainage position Staff workflow Future business growth A compact machinelessens the spaciestake,however it shall be equally capacious to meet daily business necessity.

A café will not require the same type of machine as a hotel banquet kitchen Choose the Right Type Again, in small kitchen businesses, an undercounter commercial dishwasher may suffice.

Measure Your Space Also, validate area available for dishwasher, loading zone, unloading zone, drainage and water requirement along with staff movement A poor kitchen layout may result in a huge bottleneck for the entire kitchen. Consider Energy and Water Efficiency One way to help offset operating costs over time are machines that are water-efficient and energy-efficient. This especially matters for businesses that use the dishwasher multiple times a day.

Usually, it is made from stainless steel, ideal for professional kitchen use and heavy duty. Think About Maintenance Opt for a dishwasher that is easy to clean, service and maintain.

Note: Check installation requirements before buying.
