Have you ever seen your grandma drying food in sunlight in your childhood? If yes, then exactly she is doing some science with food which is known as dehydration or drying which is quite an ancient method to preserve food.
Drying is a process where water is removed from the food to prevent the growth of any bacteria or other microorganisms. Food preservation in sunlight still has been practice in many rural areas around the world.
The reduction of moisture content has a huge benefit of preserving the vital nutrients in the form of enzymes that provides an immense source of energy. The method of food preservation is simple, quite safe, and can be used for different types of food such as fruits, vegetables, and meat. In this modern era, a machine that works on the principle of dehydration is called a food dehydrator.
The food can be dehydrated by several means such as sun drying, oven drying, and an electric process. The sun drying is usually affected much with the weather conditions because even in sunlight, the moisture in the air can produce more water in food left the food soggy.
While drying in oven is a convenient way to dehydrate food items but those are expensive and energy cost is high. Some food requires low drying temperature which is hard to maintain in oven results a high risk of scorching during the process and makes food darker and brittle.
The best quality dried food can be produced by an electric food dehydrator, equipped with a good ventilation system, a heat source, and rows of trays to keep a large number of food items. It can maintain low temperatures and consumes less energy.
How To Use A Food Dehydrator
some of the features are very important before buying a good food dehydrator such as space, smart thermostat, automatic shut-off timer, heating element, vacuum, and a fan. One of the important features of this kitchen appliance is the capacity in the form of slide-out or stackable trays mostly covers the space of about >10 square feet. Keeping in mind the size requirements according to the food you intend to dry. Here a guide which you can follow:
Variable Temperature Ranges:
An adequate temperature range for a dehydrating food is in the range from 85 F / 29 oC to 155 F / 68 oC, higher or lower than this temperature can do serious damage. A constant temperature during the process of dehydration with sufficient airflow is an important feature, higher or lower the temperature can cause food overcooked or soggy.
Fan For Sufficient Airflow:
Usually, the dehydrators are designed to have a built-in fan. These fans can circulate the air through the food evenly by absorbing the moisture in the food and replace it with dry air. There are two adjustable speeds in the fan, at the start, a high speed can absorb the moister at the upper surface of food, and then the low speed can gradually absorb the remaining moisture.
The position of the fan can be horizontal or vertical. The flow of the air in a horizontally situated fan is from top to bottom considered as a better system than a vertically situated fan because the airflow can be blocked by the shelves.
Timer And Automatic Shut-Off
A timer with automated shut-off is considered as a “luxury add-on” in your appliance. Without having a timer can prevent the ability to use it overnight, but the addition of the convenient features can help you to turn off the machine at the midnight without getting up.
