Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of traditional Chinese medicinal material processing, and relates to a traditional Chinese medicinal material processing device, in particular to a traditional Chinese medicinal material processing device system and method integrating moistening, steaming, steam explosion, drying and rectification. BACKGROUND

[0002] Moistening, steaming, steam explosion, drying and rectification technologies related to traditional Chinese medicinal materials are all traditional Chinese medicinal processing technologies, which are widely used by industry personnel according to the characteristics and properties of materials.

[0003] Traditional Chinese medicinal material moistening technology is an important link in the processing of traditional Chinese medicinal materials, aiming to soften the medicinal materials through water, steam or other solvents, so as to facilitate subsequent slicing, crushing and other processes, and can effectively ensure the quality and nutritional components of traditional Chinese medicinal materials. It is suitable for all traditional Chinese medicinal materials that need to be softened, especially those with hard texture and difficult to cut. There are many types of traditional Chinese medicinal materials, and the moistening conditions of different medicinal materials (such as water temperature, time, solvent type, etc.) are different. At present, there is no unified moistening standard in the industry, resulting in a lot of randomness in the processing of different enterprises or individuals, which affects the consistency and stability of medicinal materials.

[0004] Traditional Chinese medicinal material steaming technology is a traditional processing method for traditional Chinese medicinal materials. Through the action of steam, the medicinal materials are softened and matured, which helps the extraction and transformation of effective components. Steaming technology is suitable for traditional Chinese medicinal materials that need to be softened, matured or changed in medicinal properties, such as Huangjing. Steaming is a key link in the processing of traditional 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 accurately controlled, otherwise it may affect the medicinal properties and effective components of medicinal materials. However, the current control of steaming process mainly depends on experience, lacks precise data support and automatic control means, which increases the difficulty and uncertainty of the process.

[0005] Traditional Chinese medicinal material steam explosion technology is a new processing technology for traditional Chinese medicinal materials. Through the action of high-pressure steam, the cell wall of medicinal materials is broken, thereby improving the extraction rate of effective components. As a new processing technology for traditional Chinese medicinal materials, steam explosion technology has the advantages of high efficiency and environmental protection, but still faces many limitations in practical application. On the one hand, the technology requires high equipment and large investment cost; on the other hand, due to the involvement of extreme conditions such as high temperature and high pressure in the steam explosion process, the adaptability of medicinal materials has not been fully studied, resulting in poor application effect in some medicinal materials.

[0006] Traditional drying methods such as sunning and drying have low efficiency and are prone to contamination. Drying is the last step in the processing of medicinal materials and is crucial for the preservation and efficacy of medicinal materials. However, in actual operations, some enterprises or individuals often choose inappropriate drying methods due to lack of professional knowledge or experience, resulting in high temperatures, long drying times, and loss of nutrients, color changes, and reduced efficacy of medicinal materials.

[0007] Traditional drying methods such as sunning and drying have low efficiency and are prone to contamination. Drying is the last step in the processing of medicinal materials and is crucial for the preservation and efficacy of medicinal materials. However, in actual operations, some enterprises or individuals often choose inappropriate drying methods due to lack of professional knowledge or experience, resulting in high temperatures, long drying times, and loss of nutrients, color changes, and reduced efficacy of medicinal materials.

[0008] The existing technology for processing and treating medicinal materials is mostly single-function, such as CN204932907U, CN217772804U, etc., lacking an integrated processing technology for medicinal materials. Integrating and coupling technologies such as medicinal material moistening, steaming, steam explosion, drying, and vacuum rectification into a medicinal material processing technology is the development trend, 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 traditional Chinese medicine, and protecting and inheriting traditional Chinese medicine culture.
