What is a food dehydrator and what are its advantages?

Throughout history, people have always been concerned about preserving their food. For this age, such an interest is no exception. So, thanks to the relevant technological advances, you can dehydrate your food at home.

A food dehydrator is characterised by giving new textures and flavours to any vegetable, fruit or meat. This is possible thanks to the fans and the flow of heat that is spread across the trays. These features allow the food to dehydrate evenly.

  • Preserve food naturally for a long time
  • Ability to dehydrate several foods at the same time, thanks to the large number of trays
  • Provides textures and new flavours to food
  • Can be washed in the dishwasher
  • Food does not retain all its nutrients
  • Not all meat can be dehydrated, as it must meet certain conditions (lean)
  • Not all dehydrators have a thermostat or digital timer

What precautions should I take when using a food dehydrator?

Don’t be afraid to add the food you wish to preserve for a period of time to one of its adjustable trays. However, when dehydrating meat, you must make sure that it is lean. If it is not, and due to the oxidation of the fat, it could emit bad odours over time

Keep in mind that the food will not retain all the nutrients. Exposure to heat means that vitamins such as C.A.B1 and B3 do not survive. At the same time, the lack of moisture in the food means that it does not satisfy the appetite. This is something that should be looked at closely, as consuming them in large quantities would worsen your health.

It should be noted that not all dehydrators have a thermostat or timer. However, most dehydrators are able to optimally preserve any vegetable or fruit.

Food dehydrator with or without thermostat – what to look out for?

Food dehydrators come in a variety of models. Some have many or few trays. Others, however, have a timer or thermostat. These devices have small variations that can be observed in these aspects:

Without thermostat With thermostat
No control over the dehydration process Intervention in the dehydration process is possible
No different drying times More than 19.5 drying times

Food dehydrators retain more characteristics than those mentioned above. There are some with stainless steel trays and others with more space in the trays. There are certain models whose trays are adjustable in height.

Buying criteria: factors that allow you to compare and rate the different food dehydrator models

When making a purchase, every single detail must be taken into account. This is impossible, as the average buyer has no idea of what makes a product good. Therefore, it is essential to create your own criteria in order to select the best one.


Do you want your dehydrator to dry your food evenly? Then power is an important point to consider. The following will depend on it: the power consumption and the time it takes to dry the food. It is advisable to select one that does not exceed 240W. This way it will not consume so much electrical energy and it will dry quickly.

Number of trays

To determine the importance of this point, it is important to check your individual needs. First you should identify what type of food you usually dehydrate and how often you dehydrate it. If you do it constantly, it is essential to choose one that has several trays.

At the same time, if you dehydrate meat or poultry, it is crucial that the number of trays is not so large. Since the importance here comes down to their ability to adapt to any height. The opposite is the case if you carry out this activity with fruits or vegetables. In this context, a large number of trays is ideal.


If you have a dishwasher, you will want the dehydrator trays to be washed there. This is why it is important to check that they are BPA-free, as putting them in the dishwasher will be more than easy.
