The Difference Between Home Professional Dishwashers and Those Used in Restaurants

March, 2014 by Alma Abell

There are two types of machines that are sometimes referred to as professional dishwashers. The first type is really just a high-end home dishwasher, and the second is what you would actually see in the back room of a restaurant. In most cases, these machines are very different from each other.

A “pro” dishwasher for the home is typically finished in brushed stainless steel and has a large capacity. Its maker may boast of how quiet it runs or how efficient it is at removing food residue and other soil from the dishes. Typically, it will also include a water heater to increase the temperature of incoming water from normal household levels to levels that are capable of sterilization. Professional-grade dishwashers also tend to be more durable than their mass-market counterparts, so they’re good for families that are large enough to generate several loads’ worth of dirty dishes every day. This is surprisingly easy for a large family to do if all three meals are eaten at home, so a big, durable machine from a supplier like can be the perfect solution for such households.

Someone running a restaurant will not be interested in these cool-looking home versions. Instead, he or she will think of something much different when hearing the term “professional dishwashers.” A big restaurant model is often a very long machine that uses a conveyor belt. Dirty dishes are put on one side of the conveyor, which draws them through a semi-enclosed two- or three-stage section. Inside this box, the dishes will be pre-rinsed, sprayed with high-pressure soapy water, and then given the finishing rinse. The dishes keep moving throughout the process so that clean dishes are constantly coming out of the other end. Dishwashing employees must remain alert to grab the exiting dishes and put them away, or else the dishes can eventually pile over the small barrier at the end of the belt and fall on the floor.

Restaurant machines like this are neither sleek nor pretty. They use smooth, rather than brushed, stainless steel so that they don’t corrode rather than to look good. A truly industrial, professional machine is therefore something almost no one would want in their house. Fortunately, this kind of washing power isn’t needed in even the busiest of homes. Therefore, a professional-grade model, rather than an actual industrial one, is the best bet for the homeowner.
