Technical Field
[0001] This utility model relates to the field of highland barley flour technology, specifically a low-temperature drying device for highland barley flour production. Background Technology
[0002] Barley flour is a type of flour made from barley, possessing unique nutritional value and profound cultural significance. Barley, scientifically known as highland barley, is a type of barley that primarily grows in the Qinghai-Tibet Plateau region at altitudes above 4000 meters. Barley flour is edible and a staple food in Tibet. It also refers to noodle products made from barley flour. Barley flour is rich in minerals, vitamins, natural chlorophyll, antioxidant enzymes, flavonoids, and other active substances. The production process of barley flour includes washing and drying the harvested barley, hulling, and grinding it into flour.
[0003] In existing technologies, low-temperature drying technology for highland barley flour is an advanced method for improving the production efficiency and quality of highland barley flour. Highland barley, a grain crop mainly grown in high-altitude and cold regions, is rich in nutrients, containing various beneficial components such as β-glucan, dietary fiber, vitamins, and minerals. Due to its unique growing environment and post-harvest processing requirements, traditional drying methods are insufficient to meet the needs of modern production. Therefore, the application of low-temperature drying technology has become an important means to improve the quality of highland barley flour. Low-temperature drying technology controls the temperature during the drying process, avoiding the destruction of nutrients in high-temperature barley flour, while reducing energy consumption and improving drying efficiency. This technology typically involves the use of specialized drying equipment, such as devices with low-temperature drying mechanisms. These devices can uniformly dry highland barley flour at lower temperatures, maintaining its color, texture, and nutritional value. Low-temperature drying also helps prevent the growth of microorganisms and the oxidation and spoilage of food, thereby extending the shelf life of highland barley flour. Therefore, we propose a low-temperature drying device for highland barley flour production. Utility Model Content
