Description

Technical Field

[0001] The invention relates to the technical field of rose essential oil extraction, in particular to a rose essential oil raw material separation and extraction device and a method thereof. Background Art

[0002] During the extraction process of rose essential oil, solvent extraction can be used. Organic solvents such as ethanol can be used to penetrate deep into the petal cells to dissolve the precious essential oil components. After careful filtration and evaporation, pure and rich rose essential oil is left. It not only retains the natural fragrance, but also contains the nourishing and healing power of roses.

[0003] The patent with publication number CN221535706U discloses an oil-water separation device for rose essential oil extraction, including a storage mechanism, a separation cylinder and a liquid level observation component arranged on the outer wall of the separation cylinder; the separation mechanism, the controller and the electric telescopic rod are electrically connected through wires. When the staff observes the liquid level of the rose essential oil liquid inside the separation cylinder through the liquid level observation component, at this time, the staff uses the controller to drive the electric telescopic rod, and further adjusts the height of the oil-water separation membrane through the action of the electric telescopic rod, so as to facilitate the oil-water separation of rose essential oil liquids with different liquid level heights.

[0004] However, during the rose essential oil extraction process, the petals are easily left on the inner wall of the extraction tank and the fan blades of the stirring device after being stirred, which not only takes extra time to clean, but also affects the continuity of the overall production process; in addition, since the petals themselves have strong water absorption, even after the extraction process is completed, some solvent containing essential oil will remain in the petal residue. If this part of the residual solvent is directly discarded, it will cause a waste of resources, and manually squeezing with a filter bag to recover this part of the solvent will increase the labor intensity of the manual labor.

[0005] In view of this, we propose a rose essential oil raw material separation and extraction device and method. Summary of the invention

[0067] Furthermore, a frame edge slide groove 3110 is opened on the side wall of the placing frame 311 away from the stirring device 200, and a frame body through groove 3111 is opened on the side wall of the placing frame 311 close to the stirring device 200.

[0068] Furthermore, the placement frame 311 cooperates with the filter screen 312 to allow the rose petals to contact with the organic solvent while the petals will not leave the inside of the placement frame 311. The connecting bracket 313 is used to allow the placement part 310 to be fixed on the outer wall of the mounting roller 230 as a whole, and the limiting frame 314 is used to limit the movement range of the internal structure of the transmission part 320.

[0072] Furthermore, when the petal processing device 300 rotates clockwise, the pawl 322 immediately comes into contact with the fixed ring tooth 130 and rotates, thereby driving the rotating disk 321 and the reciprocating screw 323 to rotate, and then driving the limit slider 324 to move up and down inside the limit frame 314. After the limit slider 324 moves downward to the limit distance, the inclination angle of the connecting rod 326 changes, and drives the movable plate 325 and the extrusion part 330 to move as a whole inside the placement frame 311.

[0073] In this embodiment, Figure 10-11 As shown, the extrusion portion 330 includes an extrusion plate 331, a limiting protrusion 333 disposed at the corner position of the outer side wall of the extrusion plate 331, and a pressure spring 334 disposed on the outer side wall of the limiting protrusion 333;

The movable cover plate 343 is rotatably connected to the top of the recovery frame 341 through a hinge.

[0077] Furthermore, during the movement of the squeezing plate 331, the space inside the placement frame 311 is continuously reduced, thereby squeezing out the solution absorbed by the rose petals. After the limiting protrusion 333 on the squeezing plate 331 extends to the inside of the limiting hole 3410 under the action of the pressure spring 334, the stirring motor 210 is temporarily turned off. Subsequently, the operator pulls the recovery part 340 together with the squeezing part 330 out of the placement frame 311 as a whole, and recovers the rose petals squeezed into the recovery frame 341.
