3rd place: Rosenstein & Söhne Dehydrator 250 W

The Rosenstein & Söhne Dehydrator is made of plastic and thus its quality makes an inferior impression. The device is self-explanatory in its function and produces a satisfactory result. Cleaning is simple, but traces of use are already noticeable on the drying levels after the first applications.

  • When using a dehydrating device with a stacking system, make sure that you put the food that takes the longest to dry on a lower level. The heat rises upwards through the drying levels and is, therefore, strongest at the bottom.
  • The thinner you cut the food, the faster it dries.
  • Distribute the food with some distance on the drying grid so that the air can circulate well.
  • Spread a little lemon juice on the food to preserve the colour.
 

In the run-up to the test, we defined practical requirements and the following test criteria:

Apple and banana chips produced with the WMF automatic dehydrator
The WMF automatic dehydrator

  • Handling
  • Processing and
  • Functional scope
  • Cleaning

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.

Product selection

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.

A healthy lifestyle plays an important role for more and more people. In addition to physical activity, a balanced diet is essential. With small helpers such as drying machines, food can be prepared in such a way that it is tasty on the one hand and on the other hand can develop its full potential with regard to the nutrients it contains. But what is a drying machine and what possibilities does it offer you?

A drying machine is basically a small oven. Its task, however, is not to cook, bake or heat food, but to dry it gently. This is done by distributing heat evenly and uniformly inside the appliance. Although the optimum temperature for drying food varies considerably, it is generally between 40 and 70 degrees Celsius. The heat generated in the device ensures that moisture is removed from the desired food for several hours. The result of dehumidification is dried food that still contains the same nutrients but can be stored for a much longer period of time. How long the drying process lasts depends primarily on the food to be dried. The more moisture it contains, the longer the drying process takes.

Depending on the model, there are large differences in the drying process. While inexpensive models usually only have a few settings, higher quality models offer some advantages. Even if high-quality models have numerous settings, they are still easy to operate. Adjustable thermostats and digital timers ensure that you always have an eye on the drying process.

The advantages of automatic drying machines are quite varied, which is why they have enjoyed increasing popularity in recent years. Probably the most important advantage is the shelf life of food. Due to the gentle drying process, food can be preserved for years without losing important nutrients such as vitamins. In addition, the use of preservatives, which are often used in the food industry to prolong the shelf life of products, is not necessary. However, there are only a few foods that cannot be dried with the help of a drying machine.

Another important aspect is the financial factor. Drying machines can help you save money in many ways. For example, a dehydrator offers you the opportunity to preserve older foods instead of simply throwing them in the garbage. Unpleasant spots on fruit or vegetables can be easily removed and the rest of the product dried. With this knowledge in mind, you can also buy reduced-price groceries that expire in no time. After drying in a drying machine, any data no longer plays a role. In addition, automatic dryers are significantly better than ovens in terms of energy efficiency. This consumes significantly more electricity and is noticeable in the household budget when used regularly. Since there are inexpensive entry-level models starting at 30 euros, there is no doubt that automatic drying ovens are the cheaper alternative.

Nowadays, sustainability is also an essential aspect that many people attach importance to. Since older foods are particularly suitable for drying, automatic drying machines ensure that considerably less biological waste is produced. Seen in this light, it is even possible to kill two birds with one stone. On the one hand, you can make tasty and healthy snacks, while on the other hand, you have to throw away less food.

And don't forget the space advantage of working with a drying machine. Since dried food only has about one-sixth of the volume of the original product, it can be stowed comfortably and space-saving after drying. The small size of the dried food also has a further advantage. You can store a wide variety of foods in larger quantities and thus ensure that you always have the right food in the house.

This question cannot be answered in detail in a hurry. In the end, it depends on your own creativity. Since all fresh foods such as fruit, vegetables, meat or fish can basically be dried, it is primarily up to you which foods you want to dry and process into delicious and healthy snacks.

One of the most popular snacks that can be made with the help of a drying machine is the so-called fruit leather. This is a dried fruit puree, which is a healthy alternative to gummy bears or similar delicacies. For this purpose, fruits are chopped according to taste, pureed and applied to a baking foil in thin strips. After drying, the strips have a rubber-like consistency and, in addition to fructose, also contain lots of vitamins. Fruit leather is therefore ideal not only for your own consumption but also as a gift for family and friends.

Beef Jerky is also very popular. The delicious snack from the USA is also becoming increasingly popular in Germany. In the trade Beef Jerky is however a rather expensive and also not particularly healthy product. 100 grams of Beef Jerky cost in almost all cases at least six euros and are also processed with numerous additives. If you are still looking for a protein-rich and healthy snack, then the dried meat from the drying machine is probably the best option. So you can choose for yourself which meat you want to dry and completely dispense with the use of preservatives or flavour enhancers during production.

With a view to fruit and vegetables, all doors are also open to you. Cut into fine slices, you can process the food of your choice into savoury or fruity chips, which lose no nutrients during the drying process. Instead of greasy and unhealthy chips from the supermarket, you can make your own chips to your liking and offer a healthy alternative.

Even herbs can be used in a variety of ways in the vending machine. Among other things, you can make your own vegetable broth. All you have to do is dry traditional soup vegetables with the automatic dryer and then finely crush them. In this way, you make your own vegetable broth, but at the same time, you do not use any preservatives as they can be found in industrially manufactured products.

If you are interested in purchasing a drying machine, you should not under any circumstances take a blind look and make an ill-considered decision in favour of a model. Since there are a lot of differences between the different models, you should consider some aspects first to find the ideal machine for your individual needs.

The market offers a large number of models, which are oriented according to need and household size. If the device is to be used very frequently later and is to dry different foods such as meat, vegetables or fruit, a larger model is recommended. Otherwise, it will take a lot of time, while at the same time energy efficiency will decrease significantly. However, if only small quantities, such as herbs, are to be dried, a small appliance is perfectly sufficient. The size of the dehydrator also plays a major role in other respects. In this way, it must be possible to ensure that the hot air can flow unhindered out of the appliance. There should, therefore, be sufficient space in the kitchen to set up the automatic dryer in such a way that the hot air does not cause any damage in the kitchen or the machine itself is affected.

Drying machines offer a variety of possibilities, but these should not be to the detriment of the household budget. For this reason, it is advisable to compare the power consumption of the different models. The most important indicator for this is the wattage indicated on the packaging. This, in combination with the manufacturer's data, allows you to evaluate which device works most efficiently. All you have to do is compare which foods take how long to dry and what wattage they have.

Not all dryers are the same. Although all models have the same function, the range of functions and the accessories supplied can vary greatly. Accordingly, it is worthwhile in any case to think about the desired accessories. Special inserts are required to enable drying to take place as quickly as possible. Sieve or grid inserts ensure that the warm air can also reach the dried material from below. Thus they significantly reduce the time required. For the drying of meat or fish, bowl inserts are also required in order to achieve optimum results.

With regard to the characteristics of a drying machine, the question often arises for many people as to why the task cannot also be performed by the oven. Basically, a baking oven offers some characteristics that also characterize automatic dryers. On the other hand, regular use of the oven is accompanied by disadvantages that you can prevent by using an automatic dryer. For example, the electricity consumption of automatic dryers is significantly lower, as the area to be heated inside is very small. In addition, even small automatic dryers usually have more rails than a standard baking oven. This means that you can dry several foods at the same time during a single process.

Probably the most important aspect in favour of automatic dryers and against the oven is the temperature. On many ovens this temperature cannot be set precisely. However, since different foods should be dried at different temperatures to achieve an ideal result, precise adjustment is essential. This is often only possible with automatic dryers because you can set low temperatures yourself. Many ovens, on the other hand, cannot be set below 90° C at all. This temperature is already much too high for many foods such as mushrooms or herbs to ensure gentle drying. All in all, it is quite clear why the purchase of an automatic dryer is a sensible alternative to the oven in any case.

In case of doubt, both the domestic oven and the microwave can be used to dry food. A conscientious and above all gentle drying, however, is only possible through the use of an automatic dryer. It is important that you intensively consider which requirements the appliance of your choice should meet before buying. The result will be long-lasting and nutritious snacks that you can make within a few hours, depending on your mood.
