Description

Technical Field

[0001] The invention belongs to the technical field of Chinese medicinal material processing, and relates to a Chinese medicinal material processing device, and in particular to an integrated processing device system and method for moistening, steaming, steam explosion, drying and distillation of Chinese medicinal materials. Background Art

[0002] Technologies related to Chinese medicinal materials such as moistening, steaming, steam explosion, drying and distillation are all Chinese medicine processing technologies, which are widely used by industry personnel based on the characteristics and properties of the materials.

[0003] The Chinese herbal medicine moistening technology is an important part of the Chinese herbal medicine processing process. It aims to soften the herbs through water, steam or other solvents to facilitate subsequent slicing, crushing and other processes, which can effectively ensure the quality and nutritional content of Chinese herbal medicines. It is suitable for all Chinese herbal medicines that need to be softened, especially those that are hard and difficult to cut. There are many kinds of Chinese herbal medicines, and the moistening conditions (such as water temperature, time, solvent type, etc.) of different herbs are different. At present, there is no unified moistening standard in the industry, which leads to greater arbitrariness in the processing process of different companies or individuals, affecting the consistency and stability of the herbs.

[0004] Steaming technology for Chinese medicinal materials is a traditional method for processing Chinese medicinal materials. Through the action of steam, the medicinal materials are softened and matured, and it is helpful for the extraction and transformation of medicinal ingredients. Steaming technology is suitable for Chinese medicinal materials that need to be softened, matured or have their medicinal properties changed, such as Polygonatum sibiricum. Steaming is a key link in the processing of Chinese medicinal materials, and its process is complex and delicate. The steaming temperature, time, pressure and other parameters of different medicinal materials need to be precisely controlled. Any slight deviation may affect the medicinal properties and effective ingredients of the medicinal materials. However, the current control of the steaming process mostly relies on experience, lacks accurate data support and automated control methods, which increases the difficulty and uncertainty of the process.

[0005] Steam explosion technology for Chinese herbal medicines is an emerging processing technology for Chinese herbal medicines. It uses high-pressure steam to rupture the cell walls of the herbal medicines, thereby increasing the extraction rate of the effective ingredients. As an emerging processing technology for Chinese herbal medicines, steam explosion technology has the advantages of high efficiency and environmental protection, but it still faces many limitations in practical applications. On the one hand, the technology has high requirements for equipment and high investment costs; on the other hand, since the steam explosion process involves extreme conditions such as high temperature and high pressure, the adaptability of the herbal medicines has not been fully studied, resulting in poor application effects in some herbal medicines.

[0006] Traditional Chinese medicine drying technology is an important part of the processing of traditional Chinese medicine. Traditional methods such as airing and drying have problems such as low efficiency and easy pollution. Drying is the last step in the processing of traditional Chinese medicine and is crucial to the preservation and efficacy of medicinal materials. However, in actual operations, some companies or individuals often choose inappropriate drying methods due to lack of professional knowledge or experience, resulting in excessively high temperatures and long drying times, leading to problems such as loss of nutritional components, color changes, and reduced efficacy of medicinal materials.

[0007] Traditional Chinese medicine vacuum distillation technology is an efficient separation and purification technology, which has gradually attracted attention in the field of traditional Chinese medicine in recent years. This technology reduces the system pressure, allowing the mixture to boil at a lower temperature and separate the components. It is particularly suitable for the extraction and purification of volatile components and heat-sensitive components in traditional Chinese medicine. Vacuum distillation technology involves multiple subsystems such as vacuum system, heating system, condensation system, etc., with high technical complexity and high difficulty in operation. Professional technicians are required for operation and maintenance, which increases the operating costs of enterprises.

[0008] In the existing technology, most of the devices and equipment for processing Chinese medicinal materials are single-function, such as CN204932907U, CN217772804U, etc., which lack an integrated processing technology for Chinese medicinal materials. The integration and coupling of Chinese medicinal material moistening, steaming, steam explosion, drying and vacuum distillation technologies has become a trend in the development of Chinese medicinal material processing technology, which has significant advantages in improving the utilization rate and efficacy of medicinal materials, ensuring the quality and safety of medicinal materials, improving production efficiency and reducing costs, promoting the modernization and internationalization of Chinese medicine, and protecting and inheriting the culture of Chinese medicine.
