Tunnel type dishwasher

The 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 resemble a familiar household dishwasher, but it’s also true that a tunnel dishwasher is not used in everyday life. We will talk about the device, applications and features of such dishwashers in this publication. We will also give a short overview of the tunnel dishwasher, which, perhaps, will facilitate your choice of equipment if you are in the mood to buy it.

Features and applications of the machine

The tunnel-type dishwasher is called so because of the design features, and indeed the appearance of the unit. If ordinary household dishwashers have the shape of a rectangular box of small size, 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 tunnel-type dishwasher body can occupy an area of ​​15 square meters. m and more.

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

During the washing process, dirty dishes are placed in special trays, and then these trays are installed on the conveyor, where they, moving through the tunnel, are treated with dishwashing detergent, hot water and dried. At the exit we get trays with completely dry and clean dishes. Processing the dishes is very fast, so the tunnel-type dishwasher skips it in large quantities, providing great performance.

It is clear that at home or in small organizations, it does not make sense to install a tunnel dishwasher. Even relatively large cafes and bars prefer to confine themselves to dome-type dishwashers. However, in some cases, such a machine can not do. The tunnel-type dishwasher comes in handy:

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

Compound elements

What parts does this huge thing consist of? What allows her to wash mountains of dishes so quickly and efficiently? There are three zones inside the tunnel dishwasher: a dishwashing zone, a rinse zone and a drying zone.

1. The washing zone is a special bunker, quite spacious in which several powerful nozzles are installed that supply hot water. It heats up to 55⁰C. When nozzles spray water under pressure, circulating the dishes, nozzles supplying detergent are triggered, which ensures a high-quality washing.

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

2. Rinse area. Further, a tray full of dishes gets into the rinsing zone, where the monstrous pressure of very hot water flushes the detergent along with the rest of the dirt. After such an “execution” the dishes become crystal clear.
3. Drying compartment. Further, the wet dishes get into the chamber, where several powerful fan heaters are installed, which supply hot air. Under a stream of hot air, a whole tray of dishes dries out in minutes, if not seconds, and the next tray comes in next.

Ensure the normal functioning of the above zones a huge number of sensors nodes and assemblies. For example, door position sensors, a wash pump activation sensor, rinse activation sensors, conveyor lock sensors, a wash pump, a conveyor motor, etc.
