Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wheat bran processing, and more particularly to a drying device for wheat bran processing. Background Art
[0002] Wheat bran, also known as wheat bran, is a byproduct of wheat processing. It is separated from the outer layer of the wheat kernel (the bran). During the milling process to make flour, bran is removed as a thin, brown, fibrous outer layer. High in dietary fiber, it also contains several vitamins and minerals. In the food industry, bran is added to bread, crackers, cereals, and other baked goods to increase their fiber content. In the horticultural industry, bran is used as compost, providing nutrients for plant growth and improving soil structure. During the bran processing process, it is dried in a drying process to remove moisture from the bran.
[0003] However, most traditional drying devices have a relatively simple structure, and often use a hot air blower to blow air into the drying box. Since wheat bran will accumulate inside the drying box, the wheat bran at the bottom of the drying box cannot be blown by the hot air, resulting in incomplete drying.
[0004] And the dryer is used directly for blowing air. Since the dryer is directly connected to the outside air, the dust in the air will enter the drying box and mix with the wheat bran, which will easily affect the output quality of the wheat bran in the later stage. Summary of the Invention
