What is a Food Dehydrator?

A food dehydrator is a machine used to remove moisture from food to assist in its preservation. The dehydrator utilizes heat and generates air flow to lower moisture content of food before preservation. Many foods especially vegetables and fruits have between 80% and 95% water content. By lowering the moisture content using a food dehydrator, you are sure of restraining different types of bacteria, fungi, and molds from spoiling the food and lengthening its shelf-life.

The dehydrator consists of four main parts that help in drying food; heating elements, air vents, fans, and food trays. The heating element warms your food stacked in trays making it release moisture while the fan blows the moist air out through the vents. The process goes on for hours until the moisture content is lowered to about 20%. At this point, many foods can stay for many months without getting spoilt. For nuts and cereals, the enzymes remain inactive but alive.

Dehydrators dry food at 54 °C(129 F) even though making jerky requires heating meat at higher temperatures of 68 °C(154 F). The success of any dehydration process is in the application of steady temperatures and good air circulation. If the temperatures are too high, the results will be hardening of food on the outer parts but moist. This makes it vulnerable to getting damaged on the inner part.

Types of Food Dehydrator

Here are two main types of food dehydrators; the vertical flow food dehydrator and the horizontal flow model. Though both are used with good results, each comes with a number of pros and cons that a buyer should understand before making a decision on which to buy.

The Vertical Air Flow Dehydrator

This machine is designed with an up-and-down orientation to facilitate vertical movement of hot air. The heated base and fans are located either at the lower or upper part of the machine so that hot air is pushed up and escapes through the vents. The model with a dehydrator at the bottom provides better air flow because hot air easily moves up. Unlike the model with top positioned fan, the type of a fan at the top has to work harder to force hot air move downwards and force it to escape via vents fitted on the lower section.

When the fan and heater are located at the bottom, drying juicy items like tomatoes may result to the sap dripping down and damaging the machine. Because of poor air circulation associated with vertical airflow dehydrators, you can only get perfect results when you rotate the trays manually during the drying process. If you fail to rotate the trays, food closer to the heating element will dry faster compared to others in the dehydrator. This makes it unsuitable for people with busy schedules because one is required to keep checking for some time until the process is complete.

Pros of vertical flow dehydrators:

  • The machines are more affordable compared to the horizontal types
  • Vertical airflow produces better results when the type of food being dried is fish, raisins, herbs, or strawberries.
  • This dehydrator is ideal for small household units that do not require drying a lot of food.
  • Provided that the owner does not forget to rotate the trays in the drying chamber (they are therefore perfect when working at home or cooking in the kitchen because one is available).

Cons of using vertical flow dehydrators:

  • Heat distribution in this dehydrator is uneven (heated air tends to follow a specific pattern that can leave some foods only partially dry).
  • Because of poor heat distribution, it is difficult to dry some food types such as bananas, meat, and chicken.
  • The dehydrator requires full-time attendance to rotate the trays. This makes it not ideal for people with busy schedules or requiring multitasking.
  • When heating element and fan are located at the bottom, they can easily be damaged by sap that drops from some foods like meat.

Horizontal Air Flow Dehydrator

This type of dehydrator is available on stackable designs and horizontal types. The dehydrators are more expensive compared to the vertical types. Heating occurs across every tray that makes it even and, therefore, perfect for heating the even meat and tough fruits. The heating element and fan are located on the side to help drive hot air evenly.

Unlike the vertical model, tie type of machine is better or busier households since food can be placed on trays and allowed to dry without turning the trays. Many people leave the machine on at night when they are asleep or concentrating on other duties. Simply set the moisture content level you prefer and leave the machine to do the job.

Pros of horizontal flow dehydrator:

  • The machine achieves even heat distribution and drying on food stored in every tray.
  • Because there is even heat distribution, this type of machine is ideal for drying tough fruits and even jerky.
  • The dehydrator is also good for heavy duty drying such as when one is having an event, preparing winter food, and even commercial stores because of even heat distribution.
  • Since trays do not require being rotated manually, the horizontal machine is ideal for people who have very busy schedules or simply want concentration on specific tasks as food dries.
  • Food dries faster and the machine is therefore ideal for people who enjoy trying varying recipes.

Cons of horizontal flow dehydrator:

  • Horizontal low dehydrator is more expensive compared to the vertical design and therefore not ideal for small households.

How To Choose The Right Food Dehydrator For You

Depending on individual or business needs, it is important to know how to pick the ideal food dehydrator to get the highest value for money.

  • Select the right size of the dehydrator: This consideration is dependent on the amount of food that one will need to put in the machine and dry at any one time. The best type of dehydrator is the one that allows the user to put additional trays to expand its drying capacity.
  • The shape of the machine: Dehydrators in the market come in circular, round and rectangular shapes. Figure out how the dehydrator is going to fit in the kitchen, the available space, and décor preferences>
  • The number of trays the food dehydrator can hold: Factor the number of trays and food that you will need drying. Some food dehydrators have stackable trays that allow the user to stack from five to twenty while others come with just a few shelves.
  • Type of thermostat in the machine: Food dehydrators are available in two types, those with adjustable and others with non-adjustable thermostats. It is advisable to go for the adjustable model because it allows you to adjust the temperatures depending on the level of drying required and type of food.
  • Visibility of the drying process: Consider going for the dehydrator that has a clear glass door to make it easy to see the drying process without opening the chamber or stopping the process.
  • Strength and durability: Though a common plastic model will work well for those who want to dry occasionally vegetables and fruits, it is not durable. If you want a machine to make jerky and dry herbs among other hard tasks, make sure to look for a strong and durable machine.
