Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of honeysuckle extraction, and specifically to a device and an extraction method for extracting chlorogenic acid from honeysuckle. Background Technique
[0002] Currently, in the industrial production of extracting chlorogenic acid from honeysuckle, processes such as mechanical crushing and solvent extraction are often used. However, traditional equipment mostly adopts a single crushing or grinding structure, such as an ordinary blade crusher or a roller mill, and the treatment effect on fibrous materials such as honeysuckle is limited. The particle size of the crushed particles is uneven, and the proportion of coarse particles is high, resulting in insufficient contact area during subsequent solvent extraction, and the dissolution rate of chlorogenic acid is significantly reduced. Although some equipment is equipped with a screening structure, there is no effective recycling and re-grinding mechanism for non-compliant particles, resulting in some coarse particles directly entering the extraction process, causing waste of raw materials and affecting the extraction efficiency. Moreover, the traditional extraction equipment runs the crushing, grinding, screening and other modules independently, and the process connection is not smooth, prone to problems such as material blockage or insufficient repeated treatment. For example, particles that are not fully ground need to be manually returned, increasing the operation complexity and making it difficult to achieve continuous production. Therefore, we propose a device and an extraction method for extracting chlorogenic acid from honeysuckle. Summary of the Invention

[0006] Further, the feeding component includes a mounting barrel, a spiral feeding rod, a second motor, a discharge pipe, a conical barrel, and a feeding port. A mounting barrel is fixed at the right end of the surface of the fixed barrel. A spiral feeding rod is rotatably connected inside the mounting barrel.

By setting the feeding component, the large-particle honeysuckle after screening is re-injected into the grinding component for grinding.
[0007] Further, the crushing component includes a fixing frame, a mounting barrel, a third motor, a connecting rod and crushing blades. At the upper end of the surface of the fixed barrel, a fixing frame is fixed. On the right side of the fixing frame, a mounting barrel is fixed. At the upper end of the mounting barrel, a third motor is installed. On the output shaft of the third motor, a connecting rod is fixed. The connecting rod is located inside the mounting barrel.

[0009] Further, a feed pipe is fixed inside the feed port provided at the upper end of the mounting barrel. At the upper end of the feed pipe, a feed conical pipe is fixed. By setting the feed pipe, the dried honeysuckle is injected into the inside of the mounting barrel.
[0010] Further, a conical diversion ring is sleeved on the circumferential surface of the conical feed ring. The conical diversion ring is fixed at the upper end of the mounting disc. By setting the conical diversion ring, the ground honeysuckle powder is diverted.
[0011] Further, a material taking port is opened on the front side of the storage box. Inside the material taking port, a baffle is hinged.

[0012] Further, an observation port is opened on the front side of the baffle. Inside the observation port, a transparent plate is fixed. By setting the transparent plate, it is convenient for the user to observe the situation inside the storage box.
[0013] An extraction method for extracting chlorogenic acid from honeysuckle includes the following steps: S1 Raw material pretreatment and primary crushing: The dried honeysuckle raw material is continuously put into the mounting barrel through the feed conical pipe. The third motor is started to drive the connecting rod to rotate at a high speed, driving the crushing blades to perform multi-stage shearing and crushing on the raw material. During the crushing process, the material forms a vortex inside the mounting barrel, and the raw material is decomposed into uniformly sized debris through the cross-cutting action of the blades. After the crushing is completed, the solenoid valve is opened, and the debris is evenly dispersed onto the surface of the grinding ring along the guiding action of the conical feed ring through the discharge pipe. S2 Conical grinding and dynamic stratification: Start the first motor to drive the conical grinding disc to rotate at a high speed relative to the grinding ring. The debris is subjected to extrusion, shearing, and centrifugal force in the conical gap between the grinding ring and the conical grinding disc, and is gradually refined into micron-sized powder. During the grinding process, the conical diversion ring guides the powder to flow downward along the gap of the fixed strip to avoid material accumulation. The particles that are not completely crushed, due to the dynamic balance of their own weight and rotational centrifugal force, circulate and grind in the grinding cavity until they reach the target fineness, and finally fall to the screening assembly through the conical feeding pipe. S3 Vibration screening and closed-loop feeding back: Start the vibration motor to drive the inclined screening mesh to vibrate at a high frequency. The powder is evenly distributed along the screen surface under the limiting action of the fixed retaining bars. The qualified fine powder passes through the screen holes and falls into the storage box for temporary storage. The unqualified coarse particles slide into the conical barrel along the inclined direction of the screen surface under the vibration action. The second motor drives the spiral feeding rod to rotate, sucks the coarse particles into the installation barrel through the feeding port, conveys and lifts them to the discharge pipe through the spiral, and then re-injects them into the conical feeding ring for grinding again until all the materials meet the screening requirements. S4 Continuous conveying and precise feeding: The qualified powder in the storage box evenly falls to the belt conveyor through the bottom opening. Adjust the conveyor belt speed according to the processing capacity of the reaction kettle to continuously and quantitatively convey the powder to the feeding port of the reaction kettle. During the conveying process, the material flow is monitored in real time through the transparent plate to ensure that there is no blockage and no dust during the feeding process. S5 Solvent extraction and gradient purification: Perform solvent extraction on the powder in the reaction kettle, and obtain chlorogenic acid extract through solid-liquid separation and concentration purification processes.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The device and extraction method for extracting chlorogenic acid from honeysuckle have the following advantages: 1. By integrating the shearing and crushing assembly, the conical grinding assembly, and the vibration screening assembly into the same device, continuous processing of raw materials from coarse crushing to ultrafine powder is realized. The multi-stage crushing process fully dissociates the fiber tissue of honeysuckle, and the powder particle size distribution is uniform, significantly increasing the contact area for subsequent solvent extraction. 2. Adopt the linkage design of the spiral feeding assembly and the screening mesh. The unqualified coarse particles automatically return to the grinding cavity for repeated processing, forming an internal circulation of materials. Compared with the traditional open screening process, the raw material utilization rate is greatly improved, effectively avoiding material loss caused by manual feeding back. 3. The conical surface matching design of the conical grinding disc and the grinding ring, combined with the guiding function of the fixed strip, enables the material to be affected by the dynamic balance of centrifugal force and gravity during the grinding process, realizing particle stratification and refinement. Finally, the powder reaches a specific fineness range that is fine and uniform, ensuring uniform penetration of the extraction solvent. Description of the drawings

The second motor (43) drives the spiral feeding rod (42) to rotate, sucking the coarse particles into the installation barrel (41) through the feeding port (46), conveying and lifting them through the spiral to the discharge pipe (44), and then re-injecting them into the conical feeding ring (24) for grinding again until all the materials meet the screening requirements. S4 Continuous Conveying and Precise Feeding: The qualified powder in the storage tank (1) evenly falls onto the belt conveyor (17) through the bottom opening. The speed of the conveyor belt is adjusted according to the processing capacity of the reaction kettle (16) to continuously and quantitatively convey the powder to the feeding port of the reaction kettle. During the conveying process, the material flow is monitored in real time through the transparent plate (14) to ensure that there is no blockage or dust generation during the feeding process. S5 Solvent Extraction and Gradient Purification: The powder is subjected to solvent extraction in the reaction kettle (16), and the chlorogenic acid extract is obtained through solid-liquid separation, concentration, and purification processes.
