Description

Technical Field

[0001] The utility model relates to the technical field of preparation of fermented Chinese medicine pieces, and in particular to an integrated fermentation and drying device suitable for fermented pieces. Background Art

[0002] Chinese herbal medicine slices are Chinese medicinal materials that have been processed and prepared according to the theories and methods of traditional Chinese medicine and can be directly used in clinical Chinese medicine. This concept shows that there is no absolute boundary between Chinese medicinal materials and Chinese herbal medicine slices. Chinese herbal medicine slices include some Chinese herbal medicine slices processed at the place of origin, original herbal medicine slices, and slices that have been cut and roasted. In the production of Chinese herbal medicine slices, Chinese medicine needs to be fermented to convert the effective ingredients of Chinese medicine from large molecular substances into small molecule components such as amino acids that can be absorbed by the human intestine, making Chinese medicine a new type of drug with rapid absorption and quantitative efficacy.

[0003] In the prior art, the utility model patent with the publication number CN216864190U discloses an integrated device for fermentation and drying of traditional Chinese medicine Liushenqu, including a constant temperature fermentation box, a sample rack and a water tank, the sample rack is placed in the upper part of the constant temperature fermentation box, and the water tank is placed at the bottom of the sample rack; the sample rack includes four metal round tubes and several layers of grid frame plates, one side of the metal round tube is provided with a strip notch along the axial direction, and one side of the strip notch is evenly provided with a plurality of square notches, and the square notches are perpendicular to and connected with the strip notch; the four corners of the grid frame plate are respectively provided with a support block and a cylinder, the support block is perpendicular to the middle of one side of the cylinder, and the cylinder and the metal round tube are slidably matched. It also includes a sample box, the sample box is provided with a ventilation cover, and several sample boxes are placed on the upper part of the grid frame plate. The two ends of the strip notch pass through the metal round tube. The depth of the square notch is greater than the width of the strip notch, and the width of the support block is less than the width of the strip notch. The support block is fixedly connected to the cylinder and the grid frame plate, and the number of grid frame plates is three. The sample rack is easy to disassemble and assemble, and the layer height can be flexibly adjusted.

[0004] However, in this patent, the Chinese medicinal materials are placed in a sample box, the sample box is placed on a sample rack, and then the sample rack is placed in a fermentation box for fermentation and drying. The operation is complicated, and the Chinese medicinal materials are fermented in a narrow sample box, and the temperature and humidity in the sample box cannot be guaranteed to meet the standards. In addition, this patent does not provide a stirring device or a vibration device, and the medicinal materials in the sample box cannot be turned over and moved, which may cause uneven fermentation and drying of the medicinal materials. Even if the sample box is provided with a ventilation cover, the Chinese medicinal materials in the sample box are difficult to dry.

[0005] The utility model patent with the publication number CN215082291U discloses a Chinese herbal medicine fermentation energy-saving drying device, including a device body; a fermentation tank body is provided at the upper end of the device body, a vibrator is provided on the front plane of the lower end of the fermentation tank body, and is connected to a control device through a wire; a first notch is provided at the lower end of the fermentation tank body, and a filter frame is welded at the lower end of the first notch; a filter plate is clamped at the upper end of the filter frame; a first circular hole is provided at the lower end of the filter frame, and a solenoid valve cooperates with the first circular hole, and a water pipe is connected to the lower end of the solenoid valve; a heater and a fan are provided on the lower plane of the cavity of the device body, and the wire is connected to the control device; a ventilation plate is welded at the lower end of the cavity of the device body, and is arranged on the upper end of the heater; and a vertical partition is welded on the left and right sides of the lower plane of the filter frame. The utility model provides a Chinese herbal medicine fermentation energy-saving drying device. After fermentation, the fermentation water is output through the solenoid valve, and the hopper realizes the downward transportation of Chinese herbal medicine to each mesh frame, which is convenient for multi-level drying.

[0006] However, this patent cannot detect the temperature and humidity in the fermentation device in real time and make adaptive adjustments. During the fermentation process, the fermentation temperature is an important factor affecting the growth of the strain and the important fermentation effect. The appropriate temperature can promote the growth and reproduction of the strain, and is also beneficial to the conversion of important effective ingredients. For example, if the fermentation temperature is too high, it will affect the reaction rates of various enzymes, change the synthesis direction of bacterial metabolic parameters, affect the metabolic regulation mechanism of microorganisms, affect the physical and chemical properties of the fermented products, and then affect the kinetic characteristics of the fermentation and the biosynthesis of the products. In addition, the effect of humidity on the fermentation effect during the fermentation process is also more significant. The appropriate humidity can keep the important effective ingredients stable, and is also beneficial to the growth and reproduction of the strain. When the humidity is too high, harmful bacteria are easily bred and mildew occurs. Excessive dryness will lack water, which is not conducive to the growth and metabolism of microorganisms.
