Hullesbarrey, also known as naked barley, barley, or rice barley, is a cereal crop in the Poaceae family. Due to the separation of its inner and outer husks, the grains are exposed. It is mainly produced in Xizang, Qinghai, Sichuan, Yunnan and other places in China, and is the main food of Tibetan people. Highland barley has a history of about 3500 years of cultivation on the Qinghai Tibet Plateau, extending from material culture to spiritual culture, forming a rich and ethnic highland barley culture on the plateau. It has a wide range of medicinal and nutritional values, and has launched highland barley products such as highland barley noodles, highland barley Mantou, highland barley nutritional powder, etc.

Highland barley is the main raw material of tsamba, the first of Xizang's four treasures. During the reproduction process, barley needs to be soaked and then stir fried. Our company has developed highland barley frying machine according to this feature, which is widely used in Xizang.
