Description

Technical Field

[0001] The present invention relates to the technical field of essence extraction, and in particular to a hierarchical spiral condensation essence collection and extraction device. Background Art

[0002] Essential oils are unique aromatic substances extracted from plants, such as flowers, leaves, roots, bark, fruits, seeds, resins, etc. Steam extraction is a commonly used process method. Its principle is to use steam to fully contact the extraction raw materials to extract the effective ingredients in the raw materials.

[0003] Existing extraction devices typically use a fixed placement method for the raw materials. During the steam extraction process, the contact area between the raw materials and the steam is limited and uneven. This structure results in low extraction efficiency during flavor collection and extraction, and the flavor components in the raw materials cannot be fully extracted, resulting in material waste. Furthermore, due to the uneven contact, the extraction effect is inconsistent, making it difficult to ensure product quality. Summary of the Invention

A transmission rack meshing with the transmission gear is provided in the ring frame, and the transmission rack is provided with two and symmetrically distributed along the center of the ring frame.

[0009] Furthermore, the flip frame is fixedly connected to a sleeve via a bracket disposed inside the flip frame, and the sleeve is provided with two sleeves and symmetrically distributed along the center of the flip frame.

When the turning frame rotates, the driven gear and the adjustment rack in the ring plate intermittently engage, driving the extraction box to deflect around the axis of the rotating shaft, causing the raw material to shake in the extraction box. The steam penetrates into the interior of the raw material through the hollow structure, effectively increasing the mass transfer contact area between the raw material and the steam, solving the problem of uneven contact when the raw materials are placed in a traditional fixed manner, and improving the extraction rate.

[0022] The turning frame 3 is fixedly connected to a sleeve 31 through a bracket provided inside the turning frame 3.

The sleeves 31 are slidably connected to a counterweight rod 32 through an elastic member provided inside the sleeves 31. The end of the counterweight rod 32 is rotatably connected to a sponge 33. A steam passage is provided inside the turnover frame 3 , and the sleeve 31 is connected to the steam passage via a connecting pipe provided on the outside thereof.

[0023] A raised portion 24 is provided on the inner wall of the extraction tank 2 near the storage portion 23, and a guide groove is provided on the surface of the raised portion 24. There are multiple guide grooves and they are distributed in an array along the center of the extraction tank 2. A liquid collecting box 25 is detachably installed on the outer surface of the extraction tank 2, and a guide channel 26 connected to the guide groove is provided inside the extraction tank 2.

[0024] The steam section 5 includes a delivery pipe 51 connected to an external steam unit, and the delivery pipe 51 is fixedly connected to the outer surface of the extraction tank 2 by a pipe clamp provided on its outer surface. The outer surface of the delivery pipe 51 is fixedly connected to a nozzle 52 extending into the interior of the extraction tank 2, and the delivery pipe 51 is connected to the steam channel through a branch pipe provided on its outer surface.

[0025] The working principle and advantages of the hierarchical spiral condensation essence collection and extraction device: Loading process: The operator controls the external drive unit of the extraction tank 2, driving the tilting frame 3 in uniform circular motion along a pre-set trajectory within the extraction tank 2. The extraction box 41 within the tilting frame 3 rotates synchronously with the tilting frame 3, and its external transmission gear 45 translates in a circular motion along the inner side of the ring frame 63. When the extraction box 41 reaches the loading station, the transmission gear 45 engages with the transmission rack 62 inside the ring frame 63. As the tilting frame 3 continues to rotate, the meshing driving force of the transmission gear 45 and transmission rack 62 exceeds the preload threshold of the torsion spring 46 external to the pin 43, causing the movable plate 44 to undergo angular displacement about the axis of the pin 43 until it reaches its maximum rotation angle. Based on the transmission ratio parameters of the transmission gear 45 and transmission rack 62, when the movable plate 44 reaches its maximum rotation angle, the extraction box 41, in its open state, is positioned directly below the unloading station. Through the auxiliary mechanism within the unloading section, precise and quantitative delivery of the extracted raw materials to the extraction box 41 is achieved.

[0026] After the feeding process is completed, the driving unit drives the turning frame 3 to continue to operate, the transmission gear 45 is disengaged from the transmission rack 62, and under the action of the restoring force of the torsion spring 46, the transmission gear 45 and the pin 43 rotate in the opposite direction to reset, and the movable plate 44 returns to the initial closed state, completing the closing action of the extraction box 41.

[0027] Extraction process: After the extraction material is loaded, the drive unit continuously drives the tilting frame 3 in a circular motion. The external steam unit delivers high-temperature steam via a delivery pipe 51 to a nozzle 52, which periodically applies pulsed steam jets to the extraction box 41. Because the extraction box 41 and the movable plate 44 utilize a hollow structure, the steam enters the extraction box through the array of through-holes on the box surface, fully contacting the extraction material within, triggering the evaporation and extraction of the target components in the material. During steam injection, as the tilting frame 3 continuously rotates, the driven gear 47 mounted on the end of the rotating shaft 42 moves in a circular trajectory along the inner side of the ring plate 61, intermittently meshing with the segmented adjustment racks 64 within the ring plate 61. When the driven gear 47 and the adjustment racks 64 engage, the rotating shaft 42 drives the extraction box 41, overcoming the preload threshold of the return spring 48 and generating an angular deflection about the axis of the rotating shaft 42. After the driven gear 47 disengages from the adjustment racks 64, the return spring 48's restoring force forces the extraction box 41 back to its original position about the axis of the rotating shaft 42. Because the adjustment racks 64 within the ring plate 61 are evenly spaced circumferentially, the driven gear 47 sequentially meshes with each adjustment rack 64 during its movement, causing the extraction box 41 to continuously and periodically oscillate during steam injection. This effectively increases the mass transfer contact area between the extraction material and the water vapor, improving mass transfer efficiency, ensuring uniform steam contact across all parts of the extraction material, and enhancing the consistency of the extraction effect. During the heat transfer process, the latent heat of vaporization carried by the steam molecules causes the low-boiling-point aromatic components in the raw materials to vaporize. These aromatic components then enter the condenser 22 along with the steam. Heat exchange in the condenser tubes cools the steam and liquefies it, forming a liquid mixture. After standing and stratifying, the liquid mixture naturally separates into layers based on density differences. The plant essential oil, due to its lower density than water, floats to the upper layer, while the aqueous phase settles to the lower layer. By leveraging the density and phase characteristics of the two, separation techniques such as liquid separation and centrifugation can be employed to achieve efficient separation and purification of the plant essential oil.

[0028] Nesting process: After the steam injection operation is completed, the drive unit continues to rotate the tilting frame 3. When the extraction box 41 reaches the unloading position, the transmission gear 45 and the transmission rack 62 inside the ring frame 63 once again form a gear-and-rack meshing transmission state. As the tilting frame 3 continues to rotate, the movable plate 44 completes its maximum rotation and returns to the open state.

[0029] Because the storage section 23 is arranged 180 degrees from the loading section 21, the extraction box 41 opens vertically upward when it is at the loading station and then turns vertically downward when it reaches the unloading station. When the extraction box 41 opens vertically downward and the movable plate 44 rotates to its maximum angle, the extraction box 41 reopens, and the extracted materials inside the box fall by gravity into the storage section 23, achieving centralized collection of the extracted materials.

[0030] Extraction tank 2 inner wall cleaning process: During steam extraction, high-temperature steam enters extraction tank 2, where it comes into contact with the raw material, vaporizing the aromatic components along with it. Because the inner wall temperature of extraction tank 2 is lower than the steam dew point, the high-temperature steam releases heat upon contact with the tank wall, condensing and liquefying, forming droplets that adhere to the wall. Many aromatic components in plants are water-insoluble but volatile. During steam distillation, they form an "azeotropic" system with the steam and are distilled out along with the water vapor. This steam mixture can become a breeding ground for microorganisms, affecting the quality of the subsequent extracted product. When steam is injected into the steam channel through a branch line connected to delivery pipe 51, the solenoid valve mounted on the outer wall of the connecting pipe is activated, allowing steam to enter the interior of sleeve 31 through the connecting pipe. Because the counterweight rod 32 and sleeve 31 form a steam-driven piston mechanism, the steam pressure inside sleeve 31 increases, causing the counterweight rod 32 to move axially, driving the sponge 33 toward the inner wall of extraction tank 2. When the counterweight rod 32 reaches its maximum stroke, the sponge 33 completely adheres to the inner wall of extraction tank 2, forming a sealed adsorption surface.

[0031] As the tilting frame 3 rotates, the sponge 33 dynamically absorbs condensed liquid droplets adhering to the inner wall of the extraction tank 2. When the sponge 33 moves with the mechanism to the raised portion 24 on the inner wall of the extraction tank 2, the condensed liquid droplets within the sponge 33 are squeezed out by the curved surface. The droplets converge along the guide grooves on the surface of the raised portion 24 toward the lowest point, where they are directed through the guide channel 26 provided in this area into the collection box, thereby centrally collecting the condensed liquid from the inner wall of the extraction tank 2.

[0032] This solution adopts placement part 4, which has the following advantages: Advantage 1: Multiple sets of placement sections 4 are located within the tilting frame 3. Each set of placement sections 4 contains extraction boxes 41, arranged in a circular array around the center of the tilting frame 3. The drive unit drives the tilting frame 3 to rotate at a constant speed, and multiple sets of extraction boxes 41 simultaneously enter the loading, extraction, and discharge stations, forming a continuous production process. This circular array layout allows more raw materials to be processed per unit time, and the extraction boxes 41 are evenly distributed within the extraction tank 2, ensuring steam coverage without blind spots. Compared to traditional single-station extraction devices, this increases raw material processing capacity, reduces batch-to-batch variability, and enables large-scale continuous production.

[0033] Advantage 2: A switching member 6 is provided in the flip frame 3, comprising a ring plate 61, an adjusting rack 64, a ring frame 63, and a transmission rack 62, which engage with the driven gear 47 and the transmission gear 45 at the end of the rotating shaft 42 of the extraction box 41. When the flip frame 3 rotates, the driven gear 47 intermittently engages with the adjusting rack 64 in the ring plate 61, driving the extraction box 41 to deflect around the axis of the rotating shaft 42, causing the raw material to shake in the extraction box 41, and the steam penetrates into the interior of the raw material through the hollow structure, effectively increasing the mass transfer contact area between the raw material and the steam, solving the problem of uneven contact when the raw material is placed in a traditional fixed manner, and improving the extraction rate.

[0034] Advantage three: Storage section 23 is located directly below loading section 21. Extraction box 41 opens upward when in the loading station and downward when in the unloading station. After turning frame 3 rotates 180 degrees, extraction box 41 switches from loading above to discharging below. Gravity automatically causes the raw materials to fall into storage section 23, eliminating the need for manual intervention. This symmetrical layout separates the loading and discharging stations, preventing cross-contamination, enabling fully automated continuous production, and reducing operator error.

[0035] Advantage 4: A sleeve 31 is provided within the tilting frame 3, slidingly connected to a counterweight rod 32 via an elastic member. The end of the counterweight rod 32 pivots to connect to a sponge 33. The steam passage is connected to the sleeve 31. Steam enters the sleeve 31, pushing the counterweight rod 32 outward, allowing the sponge 33 to adhere to the inner wall of the extraction tank 2. As the tilting frame 3 rotates, the sponge 33 follows the movement of the mechanism and wipes the inner wall. When it encounters the protrusion 24, it is squeezed out and condensate is discharged. The condensate is then collected into the liquid collection box 25 through the guide groove. This prevents the aromatic components in the condensate from secondary contamination of the raw materials, ensures the purity of the subsequent extraction product, and reduces equipment maintenance costs.

[0036] Advantage five: multiple groups of guide grooves are provided on the surface of the raised portion 24 on the inner wall of the extraction tank 2, and a guide channel 26 is provided inside to communicate with the detachable liquid collecting box 25 on the outer surface. The condensate converges to the guide groove along the curved surface of the raised portion 24 and flows into the liquid collecting box 25 through the guide channel 26. The detachable design facilitates regular cleaning to prevent the liquid from accumulating at the bottom of the tank and breeding microorganisms. At the same time, trace essence components in the condensate can be recovered to improve the utilization rate of raw materials.

[0037] Advantage six: the driving unit drives the turning frame 3 to rotate according to the preset trajectory. The adjustment rack 64 and the transmission rack 62 in the switching member 6 accurately control the deflection angle of the extraction box 41, thereby realizing the automation of the loading, extraction, and discharge actions of the extraction box 41. The delivery and injection of steam are also controlled by the system, which reduces manual intervention, improves production efficiency, and ensures the accuracy and consistency of operation.
