Tunnel dishwasher is a professional equipment with which you can wash a lot of dishes, spending little time on it. Visually, it differs from an ordinary household dishwasher, and at home the tunnel-type machines did not find their application.
Next, we will look at how such a dishwasher is arranged, find the differences between the right and left designs, provide you with an overview of the most popular PMM models.
Features of use
The dishwasher with a tunnel washing mechanism has earned its name due to its design features. If our usual household cars look like ordinary compact angular drawers, then the tunnel-type dishwashers look like a conveyor and a 2-in-1 tunnel. The dimensions of these units are also impressive - sometimes the PMM case occupies about 15 sq.m. premises.
Important! Tunnel dishwashers are rightfully recognized as the most productive ones - in 1 hour of work, they cope with washing about 8000 plates or other dishes.
How is washing:
- Dirty dishes, kitchen utensils, or oversized dishes are loaded into containers.
- Containers are installed in the conveyor along which they move.
- In the process of moving the dishes are swept with detergent and hot water.
- Drying also takes place there.
At the exit of such a dishwasher, the dishes are crystal clear and perfectly dry. An additional plus is the processing of dishes with high speed.
In what areas is the PMM tunnel commonly used? It is pointless to install such a device at home, in a small cafe and restaurant too. Even many large institutions are limited to dome models. But in some cases, the purchase of such an aggregate is fully justified - the tunnel machine is suitable for such establishments:
- large catering establishments;
- large hotels and hotels;
- kindergartens and schools;
- universities, etc.
How is the PMM tunnel type
This huge machine washes mountains of dishes in a short time, how does it do it? The speed and volume of washing are ensured by the close interaction of three main zones:
- washing:
- rinsing;
- drying out.
Washing area
This compartment is made in the form of a hopper with sufficient space, in which several powerful sprinklers operate, supplying streams of hot water. Warming up the water is usually up to 55 degrees. During the operation of the water nozzles, nozzles with detergent are also connected, which is sprayed onto the entire dishes for its high-quality processing.
Important! When purchasing such a PMM, take care of special cleaning products.
Rinse area
After washing, the tray with dishes goes to the next area, where under the wild pressure of well-heated water, the detergent is washed off along with the rest of the food. After rinsing, the dishes are completely cleaned and ready for the next step.
Drying zone
Further, the dishes go into the chamber with powerful heat fans that dry the plates and utensils in a few minutes (sometimes seconds) with streams of hot air.
In order for these zones to work continuously and without failures, full control is carried out using sensors and various parts. So, in the design of the PMM there are sensors that control the position of the door, sensors that activate rinsing, sensors that block the conveyor, a washing pump, a conveyor motor and other components.
Important! What is the right and left PMM? When you see such a prefix in the name of the model - this means the direction of movement of the dishes in it.
