Tunnel type dishwasher

A tunnel-type dishwasher is an industrial unit that allows you to wash a huge mountain of dishes in a short period of time. Outwardly, it does not in any way resemble a conventional household dishwasher, but it is also true that a tunnel dishwasher is not used in everyday life. We will talk about the design, applications and features of such dishwashers in this publication. We will also provide a short review of tunnel dishwashers, which may make it easier for you to choose equipment if you are determined to buy it.

Features and areas of application of the machine

A tunnel-type dishwasher is called so because of the design features and the overall appearance of the unit. If ordinary home dishwashers have the shape of a small rectangular box, then tunnel dishwashers are somewhat reminiscent of a conveyor and a tunnel at the same time. Moreover, the dimensions of the device are also impressive; only the body of a tunnel-type dishwasher can occupy an area of ​​15 square meters. m or more.

The tunnel dishwasher is rightly considered the most productive, because it can wash up to 8 thousand items in just 1 hour.

During the washing process, dirty dishes are placed in special trays, and then these trays are placed on a conveyor, where, moving through a tunnel, they are treated with dishwashing detergent, hot water and dried. At the exit we receive trays with completely dry and clean dishes. Dishes are processed very quickly, so a tunnel-type dishwasher passes them in large quantities, providing greater productivity.

It is clear that at home or in small organizations there is no point in installing a tunnel dishwasher. Even relatively large cafes and bars prefer to limit themselves to dome-type dishwashers. However, in some cases you cannot do without such a machine. A tunnel-type dishwasher will come in handy:

• in large catering establishments;
• in large hotels;
• in kindergartens, schools, higher educational institutions and institutions of additional education with a large number of students, etc.

Components

What parts does this giant consist of? What allows her to wash mountains of dishes so quickly and efficiently? There are three zones inside the tunnel dishwasher: the washing zone, the rinsing zone and the drying zone.

1. The washing area is a special bunker, quite spacious, in which several powerful nozzles are installed that supply hot water. It heats up to 55⁰C. When the nozzles spray water under pressure, pouring over the dishes, the nozzles supplying the detergent are activated, which allows for high-quality washing.

For this type of dishwasher, special detergents should be used.

2. Rinse zone. Then the tray full of dishes enters the rinsing zone, where a monstrous pressure of very hot water washes away the detergent along with the remaining dirt. After such an “execution” the dishes become crystal clean.
3. Drying compartment. Next, the wet dishes enter a chamber where several powerful fan heaters are installed that supply hot air. Under a stream of hot air, a whole tray of dishes dries in a matter of minutes, if not seconds, and then the next tray comes in.

A huge number of sensors of components and assemblies ensure the normal functioning of the above zones.For example, door position control sensors, washing pump activation sensor, rinsing activation sensors, conveyor blocking sensors, washing pump, conveyor motor, etc.
