What type of dishwasher drying is best?


When choosing a dishwasher, you need to pay attention to the drying class. There are two classes: A and B. Drying class A leaves the dishes absolutely dry, there should be no drops of water on them. In class B, on the contrary, there may be a small amount of moisture on the dishes. Therefore, you should carefully look at the drying class before buying. In addition to classes, the main types of drying are also distinguished: condensation, turbo-drying and active condensation. In this article, we will look at the main advantages and disadvantages of each of them.

Advantages and disadvantages of condensation drying

Such drying involves the treatment of dishes at the very end of the washing cycle with hot water. As a result of this treatment, steam is formed, which first rises up and then settles on the walls of the dishwasher, draining into a special water tank. The water is removed by the pump, leaving no drops or traces.

The undeniable advantages of this type of drying are: simplicity and low cost of such PMM. In addition, this method does not require a large amount of electricity, which significantly reduces costs.

Among the disadvantages of condensation drying, users note the duration of this process, which is reflected in the total time for washing dishes. In addition, small stains from water may remain on objects.

Advantages and disadvantages of turbo drying

Turbo drying requires a fan and heating, as a result of which the dishes are blown with hot air. Now many models are equipped with a similar type of drying, which makes them more affordable for consumers.

The advantages of this type are the speed in achieving the desired result and the absence of results and stains from drops on the dishes.

Among the disadvantages are the high energy consumption of the process and the higher cost of the dishwasher itself. Ranke was equipped with this type of drying only PMM from the most expensive segment.

Advantages and disadvantages of active condensation

Active drying is available in those dishwashers where a heat exchanger is installed. Hot air here blows over the dishes due to the operation of the heat exchanger, and not the fan, as is the case with a thermal dryer. Inside the PMM, there is an active circulation of hot and cold air, which, as a result of mixing, blows the dishes. At the same time, under the influence of pressure, the drying process occurs quite quickly.
When compared with the above types of drying, this type of drying has clear advantages: efficiency, no streaks on the dishes and economy in the use of electricity.

Alternative Technologies

Some manufacturers are trying to surprise consumers and invent technologies that help dry dishes and reduce energy costs. For example, there is a technology (AirDry TotalDry, etc.), according to which, at the end of drying, the PMM door opens slightly, which allows fresh air to enter from the outside, carrying out natural drying.

There is also a technology that converts moisture into thermal energy, which affects the reduction of drying time and the energy consumption of the entire process.

How to prevent unwanted stains and streaks

A significant disadvantage of condensation drying, as we have already found out earlier, are stains and drops on the surface of objects. But traces can remain with other types of drying. Therefore, in this matter, it is necessary to remember the need to use a rinse, in addition to tablets, capsules or powder. This tool helps to completely get rid of PMM owners from stains and stains on dishes.

It is worth considering that detergents in the form of tablets also contribute to the fact that the dishes after washing will look clean and shiny. This is due to the presence in their composition of substances that perfectly cleanse and do not leave unwanted marks. These are the properties that ALAPURESA tablets have: gentle cleansing without leaving marks on dishes.
