[0014] The beneficial effects of this invention are as follows: Sealed drying under vacuum negative pressure prevents the dried product from mixing with airborne pollutants and bacteria. After drying, it can be stored without the need for any additives (such as sulfur dioxide) to prevent mold and spoilage. Furthermore, the drying drum's inner cavity is equipped with a full-spectrum lamp, which not only disinfects and sterilizes but also simulates natural sunlight, ensuring the best quality and color of the dried product. A single operation yields the dried product and various primary processed products, including hydrosols and pure oils. Drying under negative pressure at room temperature preserves the original taste and nutrients of the dried product to the greatest extent possible. The interlocking mechanism drives the drying drum to rotate, achieving dynamic drying that is labor-saving, energy-efficient, and ensures uniform drying, making it more suitable for large-scale industrial and mining drying operations.
