The tunnel dishwasher is a professional equipment with which you can wash a lot of dishes in little time. Visually, it differs from an ordinary household dishwasher, and at home, tunnel-type machines have not found their application.
Next, we will consider how such a dishwasher works, we will find the differences between the right and left designs, we will provide you with an overview of the most popular PMM models.
use Features
The dishwasher with a tunnel washing mechanism has earned its name due to its design features. If the household machines we are used to look like ordinary compact angular boxes, then tunnel-type dishwashers look like a conveyor and a tunnel – 2 in 1. The dimensions of these units are also impressive – sometimes the PMM case takes about 15 sq.m. premises.
Important! Tunnel dishwashers are rightfully recognized as the most productive – in 1 hour of work they cope with washing about 8000 plates or other dishes.
How is the wash:
- Dirty plates, kitchen utensils or bulky dishes are loaded into containers.
- Containers are installed in the conveyor along which they move.
- In the process of moving the dishes are washed with detergent and hot water.
- There is also drying.
At the exit of such a dishwasher, the plates are crystal clear and perfectly dry. An additional plus is the processing of dishes at high speed.
In what areas is the PMM tunnel commonly used? At home, it is pointless to install such a device, in a small cafe and restaurant – too. Even many large institutions are limited to domed models. But in some cases, the purchase of such a unit is fully justified – a tunnel machine is suitable for such establishments:
- large catering establishments;
- large hotels and hotels;
- kindergartens and schools;
- universities, etc.
How the tunnel-type PMM is arranged
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:
- wash:
- rinsing;
- drying.
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 goes, as a rule, up to 55 degrees. During the operation of the water nozzles, nozzles with detergent are also connected, which is sprayed onto all the dishes for high-quality processing.
Important! When purchasing such a PMM, take care of special cleaning products.
Rinse zone
After washing, the tray with dishes goes to the next zone, where, under the wild pressure of well-heated water, the detergent is washed off along with the remnants of food. After rinsing, the dishes are completely cleaned and ready for the next step.
Drying zone
Then the dishes go into a chamber with powerful thermal fans that dry plates and utensils with hot air in a few minutes (sometimes seconds).
In order for the listed zones to work continuously and without failures, full control is carried out using sensors and various parts. So, in the PMM design there are sensors that control the position of the door, sensors that activate rinsing, sensors that block the conveyor, washing pump, conveyor motor and other components.
Important! What is right and left PMM? When you see such a prefix in the name of a model, it means the direction of movement of the dishes in it.
