As defined above that both the food dehydrators include some of the standard features. But there are a few things which make both appliances different from each other. The below points will make our view more clear:

A food dehydrator is a kitchen appliance that comes with a fan, multiple trays, as well as a heat source. It can easily dehydrate different types of foods at one point in time with the help of the temperature adjustable control feature. The foods are dried uniformly with the assistance of a heated airflow system.

In the case of an oven, you can also dehydrate the food but if the machine can operate at a low temperature but this is not possible. There is no temperature control feature for lowering the heat and the oven usually run at high temperature. You have to check the temperature of the oven before placing food in it.

2) Versatility

Food Dehydrators are recognized for their versatility as they can be used to dry out an extensive variety of foods. They efficiently pull moisture out of the food for ideal drying. But in the oven, you cannot heat or dry any food. There are very few foods which you can cook in the oven.

3) Number of Racks

There are lots of stacked trays (five to twelve) in the food dehydrators which accommodate a diversity of meat, vegetables, herbs, jerky, spices, etc. But in the oven, you will not find many racks. They mainly contain 2 to 5 trays in which you can dry a very less quantity of food.

4) Authenticity of Flavors

In the food dehydrators, the original authenticity of the flavors does not get the mix, but while using an oven, the flavors get the mix if you place the food on the same rack.

5) Fan

The food dehydrators comprise a fan that circulated the air evenly on all the shelves of the even drying of food whereas in the oven you will not find any air circulating fan.

In the case of the time, efficiency, and energy, it is quite easy to use a food dehydrator as it comes with the features like temperature controls in them. You have just to set the temperature and time for drying the food in the machine and the rest process will be done automatically. But, in the case of the oven, you do not get this benefit as well as it can be a little difficult to use if you are a first time user.

7) The requirement of the Supervision

The maximum numbers of food dehydrators you buy these days require negligible surveillance as you just have to put the food on the trays and set the timer accordingly.

There is no necessity always to check your food. On the other hand, while using an oven, you have to keep an eye on the entire process, and you can leave the machine unattended.

8) Nutrients and Vitamins

While drying food in the dehydrators, the beneficial enzymes like vitamins and minerals do not kill, but the oven while cooking your food, most of the vital enzymes in the food get vanished.

9) Cost of Running

The food dehydrators are energy-efficient appliances that do not affect much your electricity bills, but the oven is quite expensive to run and can put some burden on your monthly pocket.

This is confusing and murky:
There are a lot of difference between the dehydrator and oven which make them alike.

It would make more sense to say, “there are a lot of similarities between the dehydrator and oven which make them alike,” or simply,”there are a lot of differences between the dehydrator and the oven.”
