Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of superheated steam drying, in particular to a semi-enclosed low-pressure superheated steam surface continuous drying device. Background Art
[0002] The liquid in the saturated state is called saturated liquid, and its corresponding steam is saturated steam, but it is only wet saturated steam at first, and it becomes dry saturated steam only after the water in the saturated water evaporates completely. The temperature of steam does not increase during the process from unsaturated to wet saturated to dry saturated (the temperature remains unchanged from wet saturated to dry saturated). If dry saturated steam continues to be heated under constant pressure, the temperature will rise and become superheated steam. With the development of superheated steam technology, superheated steam is more and more widely used in food processing and cooking. The multi-heat steam technology used in food drying has significant advantages such as making food heated evenly, making food more delicious, and preventing the loss of vitamins.
