With the increasing demand for health products among people, higher requirements are put forward for the extraction quality and efficiency of active ingredients in medicinal and edible homologues.

[0003] Traditional extraction devices for medicinal and edible homologues have many drawbacks. Some devices have complex structures, involving numerous components and complex assembly processes, which not only lead to high production costs but also greatly increase the difficulty of equipment installation and maintenance. Once a failure occurs, it takes a long time and effort to repair, seriously affecting the production progress. During the extraction process, the separation and filtration links of some devices are inefficient, making it difficult to fully extract the active ingredients in medicinal and edible homologues, resulting in waste of resources. Moreover, in the pressure filtration stage of existing devices, the pressure is often not accurately controlled, resulting in unstable pressure filtration effects and affecting the purity and quality of the extracts.

[0036] The usage state of the present invention is as follows: The present invention has a reasonable and simple structure, low production cost, and is easy to install. When in use, first, the raw materials of medicine and food homology enter the separation and collection mechanism 3 in the extraction chamber 2 through the feeding hopper 7 from the feeding port 6. At this time, the outer shell 1 of the extraction device plays a role in protecting and supporting each internal mechanism. Then, the second motor 394 is started. The second motor 394 (servo motor or stepping motor) drives the active pulley 393 to rotate. The active pulley 393 drives the driven pulley 391 to rotate through the belt 392, thereby enabling the rotating sleeve 31 to rotate in the center of the extraction chamber 2. At the same time, the first motor 37 is started. The first motor 37 drives the active gear 38 to rotate. The active gear 38 meshes with the driven gear 310, causing the collecting rotating shell 32 to rotate relative to the outside of the rotating sleeve 31. The raw materials are in the rotating rotating sleeve 31 and are preliminarily filtered through the separation filter sleeve 35. The separation long groove 36 helps to guide the filtrate into the inside of the collecting rotating shell 32. The filtrate after preliminary filtration enters the valve device 34 through the discharge hole 33 on the collecting rotating shell 32. The cylinder 344 in the valve device 34 pushes the valve core 343 to move in the guide groove hole 342 according to the control instruction. When the valve core 343 opens the valve hole 347, the filtrate enters the collecting pipe 346 through the valve hole 347, completing the collection of the filtrate. Subsequently, the first oil cylinder 41 is started, and its piston rod pushes the first pressure filter block 44 to move to the right inside the left side of the extraction chamber 2, thereby helping to push the filter residue in the separation filter sleeve 35 to the right side. As the first pressure filter block 44 approaches the second pressure filter block 47, the raw materials after separation, extraction, and filtration can be squeezed, further squeezing out the liquid therein. The through holes 45 and the filter plate 46 on the first pressure filter block 44 can, on the one hand, allow the squeezed liquid to pass through, and on the other hand, play a role in further filtering the raw materials, thereby improving the extraction effect. After the extraction is completed, the second oil cylinder 48 is started. The piston rod of the second oil cylinder 48 pushes the second pressure filter block 47 to move to the right inside the right side of the extraction chamber 2, exposing the push-out port 55. At the same time, the first oil cylinder 41 is started again, and the first pressure filter block 44 moves to the right to push the filter residue after pressure filtration to the position of the push-out port 55. Then, the third oil cylinder 52 is started. The piston rod of the third oil cylinder 52 pushes the push-out block 54 to move downward in the guide hole 53, pushing the filter residue after pressure filtration out of the extraction chamber 2 from the push-out port 55. The second end cover 51 is fixed at the upper opening of the guide hole 53, playing a role in supporting and protecting the third oil cylinder 52. During the whole process, the first end cover 42 is fixed outside the left opening of the extraction chamber 2 through the fixing screws 43, and the cleaning pipe at its lower opening can be used to clean the raw materials or filtrate remaining inside the left side of the extraction chamber 2.
