Food preservation is a common practice that has been practiced since the ancient times that aims at ensuring that the shelf life of the given food is enhanced. 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. Food drying may depend on natural methods such as solar drying but can as well be done using a food dehydrator 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.
Food drying through the use of a nutrichef electric countertop food dehydrator usually requires a source of heat and the air flow to help extract water from the food. There are a variety of energy sources that can be used by a food dehydrator including include electric power, solar power or even a biofuel. The food dehydrator consists of various basic parts that enhance food drying 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. The most effective components in food drying include 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. The drying process continues for the set period of time till the moisture content that remains in the food do not exceed 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. The food dehydrator ensures successful food drying by maintaining adequate flow of air in the device and a constant temperature. It is important to ensure that the temperature maintained is not very 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.
