Dishwashers and dishwashing solutions for professional kitchens
Dishwashing is an essential part of the professional kitchen. It covers the whole chain of events from returning dirty dishes to storing clean ones, and includes washing, cleaning, moving and sorting. The result, i.e. clean dishes, is the sum of several elements. Knowing the factors that influence the washing result, choosing the right equipment and using and maintaining it correctly are essential for a successful outcome.
Goals for dishwashing in professional kitchens
The absolute cleanliness of the environment, tableware and cutlery is an integral part of a pleasant dining experience and is also defined by the authorities. The Nordic Food Recommendation is monitored in Finland by the Finnish Food Authority. The surface of the dish must be free of visible dirt and must not contain more than 100 microbes. The dishes must be dry. As a rule of thumb, dishes must be dry within one minute of being taken out of the machine.
The number and quality of the dishes to be washed give their own criteria for the dish handling. The circulation of the dishes must be efficient, safe and ergonomic for the workers. Hand-lifted loads, such as baskets and stacks of dishes, must not be too heavy. Low noise levels, good lighting, ventilation and the right working temperature are also essential for a pleasant working environment.
The goal of dishwashing is to produce clean dishes in the shortest possible time, in the most cost-effective way and in a pleasant working environment.
A well-functioning professional kitchen dishwashing department
The design of a dishwashing section should consider factors such as the type of kitchen, i.e. whether it is a restaurant, staff canteen, school or hospital, the number of diners, the number of dishes and utensils and the speed of circulation, the shape and materials of dishes, the space and access of the dishwashing section, and the time and cost of washing.
Dishwashing in a professional kitchen is a whole, of which the dishwasher is only one piece – though an important one. The dishwashing system includes returning dishes to the washing area, removing food waste, sorting and stacking dishes, washing, rinsing and drying, and storing and moving dishes to serving stations.
These activities are linked together in a continuous, flexible chain of operations. The solution model is always designed on a case-by-case basis.
Dishwashing uses a lot of water, electricity and detergents. Dishwashing choices can make a big difference to the environmental load in the kitchen.
Which dishwasher is best for your professional kitchen?
Dishwashers for professional use are divided into different categories. Sometimes choosing the right machine for your professional kitchen can be a challenge, as there are many different categories and within each there are many different models. Choosing the right machine will serve its user best, so it pays to get to know the different alternatives and their features.
Undercounter dishwashers are a handy choice for small spaces such as bars and day-care centres, and are suitable for washing glasses and dishes. Hood-type dishwashers offer an ergonomic solution for medium and large professional kitchens. Pot washers are designed for large professional kitchens where large dishes and equipment parts are washed. Granule washers use biodegradable granules to remove stuck-on dirt and are suitable for heavy-duty washing needs. Rack conveyor machines are efficient capacity solutions for commercial kitchens, optimising water and energy use. Flight-type washers, on the other hand, are flexible, high-capacity machines that can be tailored to the customer's needs.

In a restaurant kitchen a undercounter dishwasher supports the glass washing process, where glasses are made sparkling clean for direct use with reverse osmosis, even without separate polishing.
For a medium sized kitchen with 250-500 daily portions, a dishwashing compartment can be created around the hood machines. The dishes are sorted on the pre-washing table into baskets and transported through the pre-washing process to the hood dishwashers. The two dishwashers can be used to adjust the washing capacity as required, e.g. one can be used to wash soiled dishes and the other to wash glassware, or one can be switched off at off-peak times. This is particularly popular in locations where there is a lot of seasonal variation.
In restaurant kitchens, the undercounter dishwasher supports glass washing, where glasses are made sparkling clean for direct use with reverse osmosis - even without separate polishing.
The return of dishes for a 300-500 portion distribution kitchen is well handled by a smaller rack conveyor machine.

Dirty and stained dishes are washed separately in a granule washer, which facilitates the washing of cooking and serving pots and containers.
The dirty dishes on the trays are easily sorted and washed with a tray and cutlery washer, a flight-type washer and a rack conveyor machine. Glasses and cups are sorted into baskets for transport to the rack conveyor machine and plates are placed on the belt of the flight-type washer.
