[0020] The pressing and rotating mechanism includes a fixed box 15, a motor 14, an inner rod 401, a buffer spring 5, a sleeve 7, a stirring rod 8, a roller 9, a motor 2 16, an active rod 17 and an elliptical disk 18. The top of the fixed box 15 is connected to the top of the inner cylinder 2. The motor 14 and the motor 2 16 are installed inside the fixed box 15. The output end of the motor 14 is connected to the inner rod 401. The lower end of the inner rod 401 is elastically connected to the sleeve 7 through the buffer spring 5. The bottom of the fixed box 15 is provided with an opening adapted to the size of the sleeve 7. The bottom of the inner rod 401 is symmetrically installed with a slider 6, and the inner side of the sleeve 7 is provided with a slide groove slidably connected with the slider 6. The slider 6 and the slide groove increase the friction resistance between the sleeve 7 and the inner rod 401 to achieve synchronous rotation of the sleeve 7 and the inner rod 401. The bottom of the sleeve 7 is installed with a stirring rod 8. The two ends of the bottom of the stirring rod 8 are provided with grooves. A roller 9 is rotatably installed in the groove. The stirring rod 8 and the roller 9 are located at the upper end of the filter plate 3. When the elliptical disk 18 squeezes the toothed ring 701, the toothed ring 701 is squeezed and slides down. The sleeve 7, the stirring rod 8 and the roller 9 are driven to slide downward. At this time, the stirring rod 8 and the roller 9 contact the medicinal materials on the filter plate 3 and squeeze the medicinal materials. The motor 4 drives the inner rod 401 to rotate. The inner rod 401 drives the sleeve 7 to rotate through the slider 6. The sleeve 7 drives the stirring rod 8 and the roller 9 to rotate, so that the medicinal liquid in the medicinal materials is squeezed. When the elliptical disk 18 does not squeeze the toothed ring 701, the sleeve 7, the toothed ring 701, the sleeve 7, the toothed ring 701, the stirring rod 8 and the roller 9 slide upward due to the rebound force of the buffer spring 5. The toothed ring 701 and the elliptical disk 18 The sleeve 7, the toothed ring 701, the stirring rod 8 and the roller 9 are fitted together so as to slide up and down. The up and down sliding of the sleeve 7, the toothed ring 701, the stirring rod 8 and the roller 9 are matched with the movement trajectory of the elliptical disk 18. If the force acting on the sleeve 7, the toothed ring 701, the stirring rod 8 and the roller 9 and the up and down sliding distance are increased, the length of the sleeve 7 can be increased or the shape of the elliptical disk 18 can be adaptively adjusted, thereby overcoming the need to crush and stir medicinal materials of different specifications by the stirring rod 8 and the roller 9.

[0021] Working principle: when in use, open the end cover of the discharge pipe 201, pour the medicinal materials and water into the inner cylinder 2, and then close the end cover of the discharge pipe 201. The medicinal materials stay on the top of the filter plate 3, and the air inlet pipe 101 and the air outlet pipe 102 are connected to the external hot air circulation device to realize the circulation of hot air in the cavity between the outer cylinder 1 and the inner cylinder 2. The water in the inner cylinder 2 is heated by the hot air to precipitate the medicinal materials into the water, and the vacuum pump 14 is started. The steam generated by evaporation is subjected to the pressure of the vacuum pump 14 and enters the degassing membrane 11 through the connecting pipe 12 for filtration. The gas in the steam passes through the degassing membrane 11 and then enters the fixed cylinder 10 and the outside of the degassing membrane 11, and is discharged through the vacuum pump 14. Open valve 1, and the concentrated medicinal liquid in the steam passes through the degassing membrane 11 and the connecting pipe 2 13 into the inner cylinder 2. Start motor 14 and motor 2 16. Motor 2 16 drives the active rod 17 and the elliptical disk 18 to rotate. When the elliptical disk 18 squeezes the gear ring 701, the gear ring 701 drives sleeve 7 to slide downward, sleeve 7 stretches buffer spring 5, sleeve 7 drives stirring rod 8 and roller 9 to slide downward, at this time stirring rod 8 and roller 9 contact and squeeze the medicinal materials on filter plate 3, motor 1 4 drives inner rod 401 to rotate, inner rod 401 drives sleeve 7 to rotate through slider 6, sleeve 7 drives stirring rod 8 and roller 9 to rotate, so that the medicinal liquid in the medicinal materials is squeezed, and the medicinal liquid precipitates through the mesh of filter plate 3 and concentrates at the bottom of inner cylinder 2, opens the valve of discharge pipe 202, and the medicinal liquid is discharged from discharge pipe 202, when elliptical disk 18 does not squeeze tooth ring 701, the resilience of buffer spring 5 drives sleeve 7, stirring rod 8, roller 9 and tooth ring 701 to slide upward, so that tooth ring 701 fits with elliptical disk 18, thereby realizing the up and down reciprocating movement of sleeve 7, stirring rod 8, roller 9 and tooth ring 701, opens valve 2 of slag discharge pipe 203, and pushes the slag out of slag discharge pipe 203 through stirring rod 8.
