In order for customer service to go smoothly, it is necessary to have a sufficient amount of clean dishes available. This means that the dishwasher for the dining room should be selected based on its performance, so that there is no downtime during rush hour. But an excessive performance indicator is not very beneficial, because excess electricity is consumed, and the costs of water, washing and rinsing agents increase.
Functionality and main parameters
Industrial dishwashers for canteens in educational institutions, kindergartens, and hospitals are considered reliable helpers. There are three types of such dishwashing machines:
- conveyor dishwasher;
- dome dishwasher;
- boiler washing equipment.
The main functions of dishwashers are:
- blast cleaning of dirty dishes;
- washing with cleaning compounds;
- primary and secondary rinsing.
When buying a dishwasher, it is recommended to check:
- its performance level. To do this, calculate the number of devices passing through a dishwashing machine during one working day;
- area required for installation. It is often more convenient to install two medium-sized dishwashers than one large one;
- duration of cleaning.It is beneficial to purchase a dishwasher that can perform four to six full cycles.
The conveyor dishwasher is an excellent solution for catering canteens. The device allows you to set the temperature and control the consumption of cleaning products. Taking into account the arrangement of furniture in the industrial premises of the dining room, it is possible to choose a dishwasher with left or right loading. If necessary, additional tables and conveyors are installed.
The dome dishwasher will wash dirty dishes. The dishwasher includes tables, washing baths, food waste bins, and rinsing devices. It is possible to control the powder consumption and block the dome from sudden lifting.
The boiler-washing dishwasher for the dining room is designed for cleaning baking sheets, pots, and cauldrons. Dishwashing equipment quickly removes stuck-on food and oil residues, cleaning utensils in a few minutes.
Remember that professional dishwashers for dining rooms are very different from simple analogues in their speed of operation and loading volumes.
Continuously operating dishwashers fall into two categories:
- In a conveyor device, plates and cutlery are laid out on a special belt equipped with clamps. It is believed that the washing process in them is more thorough, because the utensils are exposed to water most of the time. There is one peculiarity - this type of dishwasher is placed exclusively linearly;
- In cassette-type machines, plates intended for washing are first placed in cassettes, which are sent to the dishwasher. This option is acceptable for small dining rooms. Dishwashing equipment is compact in size and can be placed at an angle. The work process on it can be organized by one person.
How the workflow works
Fundamentally, the operation of a professional dishwasher is practically no different from other varieties. Plates, glasses, cutlery and utensils are placed in baskets and cassettes, which fall into the washing chamber, after which the multi-stage washing process is activated.
The water supply in such dishwashers occurs through a special system. Under strong pressure, the liquid is able to penetrate into any hard-to-reach place, removing contaminants.
Examples of the best dishwashers
RLet's look at several options that can be used to equip dining rooms:
- AVAT MPT-1700.
Tunnel type dishwasher, the productivity of which reaches ninety-five complete cassettes per hour. An excellent solution for any dining room. In such a machine, cassettes filled with dishes move along a conveyor line, ending up in the washing compartment, then into the rinsing and drying departments. The end result is clean and dry dishes. The machine does an excellent job of washing cutlery, glasses and small non-standard utensils. Pots, baking sheets and large frying pans must not be washed in it.The dishwasher is made by a Russian manufacturer, is connected to a hot water supply, and is equipped with dispensing units for detergents and rinse aids. The size of the cassettes is 50 by 50 cm. The capacity of the hot water boiler is one hundred liters, the rinsing container is seventeen liters. The washing bath has several filters. The standard equipment of such a dishwasher for the dining room includes only four cassettes for plates and two for glasses. But anyone can purchase an additional number of cassettes to establish a continuous dishwashing process; - GASTRORAG HDW-80.
Dome dishwasher, with a maximum productivity of no more than five dozen cassettes per hour. The worker places the cassette under the dome, closes the lid, and the washing is done automatically. The task of the canteen employee is to change the cassettes in a timely manner. Note that this process of washing dishes is less convenient than in a tunnel-type machine. The dishwasher is made in China, has good build quality and good components. There is a tray washing function and there are containers for detergents and rinsing agents. The size of accepted cassettes is 500 by 500 mm. The equipment includes two cassettes and a basket for devices, but additional accessories can be purchased at any time; - SMEG PROFESSIONAL UD503D.
If the dining room is not too large, then this dishwasher will be the ideal solution for it. Excellent equipment, operational period reaches several decades. With small dimensions, the dishwasher is capable of washing up to forty cassettes within one working hour. The machine was assembled by Italian craftsmen, equipped with a pump for pumping out dirty water, dispensing containers for detergents and rinse aids.The device has three operating modes, which is quite good for professional equipment. Product range of such dishwashers offers device options with a capacity of 15 and 24 cassettes, which is very convenient for small cafes; - APACH AF
Another option from Italy, capable of washing up to forty cassettes within one hour. The machine has a seamless bathtub for washing dishes and a body made of stainless steel. It is possible to connect to hot water supply. The delivery set includes a dispenser for rinse aid only, cassettes for plates and mugs, and an insert for cutlery. The walls of the dishwasher are thermally insulated, the water in the chamber cools slowly, which improves the quality of washing.
Main selection criteria
The main difference between canteens is their traffic. If the room is small and food is prepared only for the organization’s employees, whose number does not exceed fifty people, it is enough to purchase a household dishwasher from Bosch.
Establishments feeding from one hundred to three hundred people should install a frontal industrial dishwasher, whose performance is at a low or medium level.
If four hundred to five hundred people pass through the dining room, it is recommended to wash dirty dishes in dome or tunnel type dishwashers, which have a capacity of forty to fifty loaded cassettes per hour.
Canteens with halls that can accommodate up to three thousand people eating in shifts during lunch must have tunnel dishwashing units that wash eighty to one hundred cassettes with dirty dishes in one hour.
In addition to sufficient performance, dishwashing equipment must be reliable. If the machine breaks down during the working day, the dining room will be paralyzed, because it will be simply impossible to wash so many dishes by hand.
