Various dried foods in a dried foods store An electric food dehydrator with mango and papaya slices being dried. This is a list of dried foods.Food drying is a method of food preservation that works by removing water from the food, which inhibits the growth of bacteria and has been practiced worldwide since ancient times to preserve food.
A dehydrator's heating element, fans and vents simultaneously work to direct hot air over the food, accelerate surface evaporation, and warm the food to also release moisture from its interior. This process continues until the food is dried to a substantially lower water content, usually less than 20%.
Mature serrano pepper plants reach a height of 0.5–1.5 meters (1 ft 8 in – 4 ft 11 in). [1] Each plant can produce up to 50 pepper berries (not true botanical pods). [1] The fruit can be harvested while they are green or ripe. Unripe serrano peppers are green, but the color varies at maturity; common colors for the ripe fruit are green, red ...

The spray drying technique was first described in 1860 with the first spray dryer instrument patented by Samuel Percy in 1872. [citation needed] With time, the spray drying method grew in popularity, at first mainly for milk production in the 1920s and during World War II, when there was a need to reduce the weight and volume of food and other materials.
In Mongolia cheese and meat are still traditionally dried using the top of the ger (tent) as a solar dryer. [3] In these systems the solar drying is assisted by the movement of the air (wind) that removes the more saturated air away from the items being dried. [2] More recently, complex drying racks [4] and solar tents [5] were constructed as ...
Material to be dried enters the dryer and, as the dryer rotates, the material is lifted up by a series of fins (known as flights) lining the inner wall of the dryer. When the material gets high enough, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.
Drying starts at the bottom of the bin, which is the first place air contacts. The dry air is brought up by the fan through a layer of wet grain. Drying happens in a layer of 1 to 2 feet thick, which is called the drying zone. The drying zone moves from the bottom of the bin to the top, and when it reaches the highest layer, the grain is dry.
