In the run-up to the test, we defined practical requirements and the following test criteria:
- Processing and
- Functional scope
In order to be able to evaluate these criteria, we have defined several tests for the dehydrators. In the first run, we produced apple and banana chips with the dehydrators. In the second run, tomatoes were dried. We were able to compare the results directly afterwards. For the drying times and temperatures, we orientated ourselves on the drying tables of the operating instructions. During use, we also paid attention to whether the devices are easy to handle, what the range of functions offers and how easy it is to clean the devices.
In order to rule out errors and to ensure the load of everyday use, each test takes place in several rounds.
The test criteria are given percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.
Our product selection is based on an observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.
