Food Drying through the Use of Food Dehydrators

There are a variety of ways that are used in preserving different kinds of food to ensure that their shelf life is increased. One of the commonly used food preservation method is food drying where the food is dried hence preventing the growth of yeasts, bacteria or molds by removing water from the food. When drying food as a preservation method, one can dry it under the solar or can make use of the food dehydrators that helps extract moisture from the given food hence aiding in preservation. The device is used on almost all common kinds of foods such as vegetables, fruits as well as animal proteins.

For a food dehydrator to perform effectively, it usually depends on a source of heat and the air flow to help extract water from the food. Food dehydrators usually depend on a variety of sources of heat for food drying including the include electric power, solar power or even a biofuel. There are various important components that are essential for a food dehydrator to enhance drying of food which may include the heating element, air vents that allow air circulation in the device, a fan as well as food trays where one can lay the food. In drying the food, the process is usually enhanced by the heating element, air vents that allow air circulation in the device and a fan which work simultaneously with each other in removing moisture from the food.

When using a food dehydrator, the heating element will warm the food allowing it to remove moisture while the fan will then blow out the moist warm air from the appliances through the air vents. This process of food drying in the food dehydrator will continue till the moisture content remaining in the food is less the 20%. The temperature needed in a food dehydrator for effective food drying usually varies depending on the type of food being dried for example most foods are usually dehydrated at 1300F while for the meat jerky, the temperature has to be increased to about 1550 F. To ensure that food drying is done in the right way, the food dehydrator usually maintains an adequate flow of air in the device and a constant temperature. The most appropriate temperature that should be maintained should not be too high to ensure that the food do not dry and become hard on the outside and the inside is moist making it susceptible to spoilage.

One need to put certain factors into consideration when purchasing a suitable food drier to use for food preservation. The most common factors put into consideration include the model of the dehydrator, the kinds of food to be dried, space one has to accommodate the food dehydrator as well as its cost.
