Description

Technical Field

[0001] This utility model relates to the technical field of flavor concentration equipment, and in particular to a flavor extraction and concentration device. Background Technology

[0002] The extraction and concentration of flavorings are core processes in the food and fragrance industry. The goal is to efficiently separate and purify aromatic substances from natural raw materials such as flowers, fruits, and plants, ultimately obtaining high-concentration flavorings or essential oils. This process typically consists of two stages: extraction and concentration. The extraction stage uses solvents to dissolve and transfer the aroma components from the raw materials, while the concentration stage removes solvents or water to increase the concentration of active ingredients. Vacuum vacuum concentration, a standard industry process, lowers the boiling point of liquids by creating a vacuum in a closed system, allowing the solvent to evaporate rapidly within a lower temperature range (e.g., 40 to 60 degrees Celsius), thus preventing heat-sensitive aromatic substances from decomposing or deteriorating due to high temperatures. Current technology commonly employs jacketed heating for vacuum vacuum concentration, where the heat transfer medium circulates within the jacketed chamber, conducting heat to the internal material through the tank walls. Although this method has high heat transfer efficiency, in actual operation, as the concentration process progresses, the solvent volume continuously decreases, causing the liquid level to gradually drop, or the solvent volume itself becomes insufficient. When the liquid level is below a certain area of ​​the inner wall of the compression tank, these areas are out of solvent contact and exposed to the heating environment. This prevents the jacketed heat energy from being effectively transferred to the material, resulting in significant heat waste and potentially affecting the stability of flavor quality due to localized overheating, as well as reducing the overall energy efficiency of the process. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0003] The main purpose of this invention is to provide a fragrance extraction and concentration device that aims to avoid heat waste and local overheating, and improve energy utilization efficiency.

[0004] To achieve the above objectives, the fragrance extraction and concentration device proposed in this utility model includes: A compression tank, wherein the compression tank is provided with an inner cavity; A jacket is provided on the outer side wall of the compression tank, and a heating chamber is provided between the jacket and the compression tank at a distance, wherein a heating medium is provided in the heating chamber; The irrigation mechanism includes a lifting bucket, a lifting assembly, and a squeezing assembly. The lifting bucket is located below the inner cavity, and the lifting assembly is located outside the compression tank. The lifting assembly is used to lift the lifting bucket, and the squeezing assembly is located above the inner cavity. After the lifting bucket carries the solvent and is lifted, it squeezes against the squeezing assembly, causing the solvent to be squeezed from the edge of the lifting bucket to the inner wall of the compression tank.

[0005] In one embodiment, the lifting assembly is provided with a slide bar that extends from the top of the compression tank, passes through the compression assembly, and connects to the lifting barrel.

[0006] In one embodiment, the cross-sectional area of ​​the cavity of the lifting bucket gradually decreases from top to bottom, and the shape of the extrusion assembly corresponds to the cavity of the lifting bucket.

[0007] In one embodiment, the extrusion assembly includes: An extrusion component, the bottom surface of which corresponds to the shape of the cavity of the lifting bucket; A sealing ring is provided around the extrusion member, and the sealing ring has a liquid outlet. When the lifting bucket is raised to below the extruder, the sealing ring surrounds the upper part of the lifting bucket, so that the gap between the extruder and the lifting bucket forms a relatively sealed space. As the lifting bucket continues to move upward, the solvent inside is squeezed out from the outlet and flows down the inner wall of the compression tank, where the solvent evaporates.

[0008] In one embodiment, the liquid outlet is provided in a plurality of locations, and the plurality of liquid outlets are evenly spaced in a ring on the side wall of the sealing ring.

[0010] In one embodiment, the bottom surface of the extruder is provided with multiple connecting grooves, which are corresponding to the liquid outlet. When the lifting tank is raised to the top, the cavity of the lifting tank fits against the bottom surface of the extruder. The connecting grooves are used for solution guidance and flow before the closed state.

[0012] In one embodiment, the cross-section of the sidewall of the compression tank is configured with multiple bends.

[0022] Please see Figures 1 to 3 This application provides a fragrance extraction and concentration device 1000, comprising: a compression tank 1 with an inner cavity; a jacket 2 located on the outer wall of the compression tank 1, with a heating chamber spaced apart from the jacket 2 and the compression tank 1, the heating chamber containing a heating medium; and a pouring mechanism 3, comprising a lifting tank 31, a lifting assembly 32, and a squeezing assembly 33. The lifting tank 31 is located below the inner cavity, the lifting assembly 32 is located outside the compression tank 1, the lifting assembly 32 is used to lift the lifting tank 31, and the squeezing assembly 33 is located above the inner cavity. After the lifting tank 31 carries the solvent and is lifted, it is squeezed by the squeezing assembly 33, causing the solvent to be squeezed from the edge of the lifting tank 31 to the inner wall of the compression tank 1.

[0023] The compression tank 1 serves as the basic space for containing materials and solvents, and its inner cavity provides a closed processing environment for the solvent. The jacket 2, through a gap with the outer wall of the compression tank 1, forms a heating chamber. The heating medium within the heating chamber can be water, heat transfer oil, or other fluids with high thermal conductivity. Its main purpose is to transfer heat to the inner wall of the compression tank 1 via thermal conduction, thereby heating the internal solvent. Furthermore, the pouring mechanism 3 is designed to achieve uniform solvent distribution. The lifting tank 31 can be made of rigid material, and its shape can be cylindrical or conical, depending on actual needs. The lifting assembly 32 can lift the lifting tank 31 through mechanical transmission, hydraulic drive, or electric push rod, raising it from below the inner cavity to the position of the extrusion assembly 33. The extrusion assembly 33 creates an extrusion effect through relative movement with the lifting tank 31. For example, it can be designed as a pressure plate with elastic elements or a rigid structure pressure block. Its purpose is to force the solvent out from the edge of the lifting tank 31 during the lifting process and allow it to flow along the inner wall of the compression tank 1.

[0024] The innovation of this application lies in solving the problem of heat waste caused by insufficient solvent volume through the design of the pouring mechanism 3. Specifically, when the lifting tank 31, carrying solvent, is raised below the extrusion assembly 33, the two form an extrusion action. Specifically, as the lifting tank 31 moves upward, its edge interacts with the extrusion assembly 33, forcibly squeezing the solvent from the edge of the lifting tank 31 and distributing it evenly to the inner wall of the compression tank 1. Thus, after being squeezed out, the solvent flows down the inner wall of the compression tank 1, forming a continuous liquid film that covers the inner wall surface even with a small amount of solvent. This design avoids localized dry burning caused by insufficient solvent, thereby ensuring efficient heat transfer to the solvent and reducing heat loss. The cooperation between the lifting tank 31 and the extrusion assembly 33 achieves forced solvent distribution, ensuring that even with a small amount of solvent, the solvent can still evenly cover the inner wall of the compression tank 1, preventing localized dry burning.

[0025] Please see Figure 2 Furthermore, this application proposes that the lifting assembly 32 is equipped with a slide rod 321, which extends from the top of the compression tank 1, passes through the extrusion assembly 33, and connects to the lifting bucket 31. This technical solution effectively solves the problem of motion stability of the lifting bucket 31 by introducing the slide rod 321.

[0026] Please see Figure 2 This application further proposes that the cross-sectional area of ​​the cavity of the lifting tank 31 in the aforementioned fragrance extraction and concentration apparatus 1000 gradually decreases from top to bottom, and the shape of the extrusion assembly 33 corresponds to the cavity of the lifting tank 31. Specifically, the cavity of the lifting tank 31 refers to the internal space structure used to hold the solvent, which can be implemented using a conical design. The purpose is to create a pressure gradient through the gradually changing cross-sectional area, thereby guiding the solvent to be extruded uniformly. The shape of the extrusion assembly 33 corresponds to the cavity of the lifting tank 31, which can be understood as the bottom contour of the extrusion assembly 33 matching the shape of the inner wall of the cavity of the lifting tank 31. The purpose is to ensure that the two form a consistent annular gap during the fitting process, avoiding extrusion direction deviation or uneven flow caused by shape mismatch. This solves the problem of uneven solvent extrusion.

[0027] Please see Figure 3This application further proposes an extrusion assembly 33 comprising: an extruder 331, the bottom surface of which corresponds to the cavity shape of the lifting tank 31; and a sealing ring 333, which surrounds the extruder 331 and has an outlet 334. When the lifting tank 31 is raised below the extruder 331, the sealing ring 333 surrounds the upper part of the lifting tank 31, creating a relatively sealed space between the extruder 331 and the lifting tank 31. As the lifting tank 31 continues to move upward, the solvent inside is extruded from the outlet 334 and flows down the inner wall of the compression tank 1, where the solvent evaporates. This technical solution, through the organic combination of the extruder 331, the sealing ring 333, and the outlet 334, achieves sealing and directional flow functions during the solvent extrusion process. The bottom surface of the extruder 331 corresponds to the cavity shape of the lifting tank 31, a design that reduces gaps at the initial stage of extrusion, laying the foundation for subsequent sealing. A sealing ring 333 surrounds the extruder 331. When the lifting tank 31 is raised below the extruder 331, the sealing ring 333 tightly surrounds the upper outer wall of the lifting tank 31, thus forming a relatively sealed space between the extruder 331 and the lifting tank 31, preventing premature solvent leakage due to uneven pressure. The outlet 334 serves as the sole solvent outlet channel. As the lifting tank 31 continues to move upward, the internal solvent is squeezed out from the outlet 334 under continuous pressure, flowing evenly down the inner wall of the compression tank 1, fully contacting the heated tank wall to achieve efficient evaporation. Furthermore, the above technical solution, combined with the conical design of the lifting tank 31, further optimizes the solvent extrusion path, ensuring that the solvent can evenly cover the inner wall of the compression tank 1, thereby avoiding localized heat waste due to uneven solvent distribution and improving overall heat transfer efficiency.

[0028] Please see Figure 3 This application further proposes that multiple outlets 334 are provided, and the multiple outlets 334 are evenly spaced in a ring on the side wall of the sealing ring 333. Multiple outlets 334 refer to several opening structures for solvent outflow on the side wall of the sealing ring 333. The purpose is to disperse the solvent extrusion location and avoid flow concentration and localized high pressure caused by single-point extrusion. This effectively solves the problem of uneven solvent extrusion.

[0029] Please see Figure 3 This application further proposes that the liquid outlet 334 is located above the side wall of the sealing ring 333, and the liquid outlet 334 is adjacent to the outermost side of the extrusion 331.

[0030] Please see Figure 3This application further proposes that the bottom surface of the extruder 331 is provided with multiple connecting grooves 332, which are correspondingly arranged with the liquid outlet 334. When the lifting tank 31 is raised to the top, its cavity is in contact with the bottom surface of the extruder 331. The connecting grooves 332 are used for solution guidance and flow before the extrusion is closed. Specifically, the connecting groove 332 refers to a groove structure with a flow guiding function opened on the bottom surface of the extruder 331. When the lifting tank 31 is raised to the top, its cavity gradually approaches and finally fits with the bottom surface of the extruder 331. During this process, the presence of the connecting groove 332 allows the solvent to continue to flow through the channel before complete closure, maintaining the dynamic balance of the extrusion process. The design of the connecting groove 332 not only optimizes the flow path of the solvent, but also makes full use of the annular and uniformly distributed characteristics of the liquid outlet 334, ensuring that the solvent can be efficiently guided to the inner wall of the compression tank 1. This technical solution effectively solves the problem of poor solvent flow before closure and prevents local residue or flow obstruction.

[0031] This application further proposes that the sidewall of the compression tank 1 be non-vertically smooth. This design alters the flow behavior of the solvent along the inner wall. When the solvent is squeezed out from the edge of the lifting tank 31 and flows down the non-smooth sidewall, the flow path is prolonged and dispersed multiple times due to the special morphology of the sidewall surface. This design avoids the rapid concentrated flow phenomenon easily caused by a vertically smooth surface, allowing the solvent to form a more uniform film coverage on the inner wall. Even with a small amount of solvent, the exposed area on the inner wall is significantly reduced. The non-vertically smooth sidewall design also works well with the heating method of the jacket 2. The heating medium in the jacket 2 transfers heat to the solvent through the sidewall, and the non-vertically smooth sidewall further optimizes the heat utilization efficiency. This design not only solves the problem of uneven solvent distribution but also enhances the overall performance of the device, demonstrating the ingenuity of the technical solution.

[0032] Specifically, the sidewall of compression tank 1 has a multi-layered bend design. This design allows the solvent to naturally remain in the recessed areas formed by the bends as the liquid level drops, ensuring continuous contact between the inner wall and the solvent. This design not only expands the effective heat transfer area but also guides the solvent to distribute evenly using the layered bends, avoiding the localized dry wall phenomenon that occurs with smooth or single-layer non-vertical sidewalls at low liquid levels.

[0033] Please see Figure 2Specifically, the sidewall of the compression tank 1 has a wavy cross-section. Specifically, the wavy design refers to constructing the cross-sectional shape of the sidewall of the compression tank 1 using a continuous, smooth curve design. In practical applications, this wavy shape can be achieved through machining, molding, or other suitable manufacturing processes. Its purpose is to eliminate the dead zones in solvent flow caused by sharp angles in multi-layered bending structures, while ensuring that the solvent can form a uniform coverage and continuous flow path on the inner wall of the compression tank 1. The wavy sidewall design significantly increases the contact area and contact time between the solvent and the inner wall of the compression tank 1 through its undulating structure. During the concentration process, even with a small amount of solvent, the solvent can flow smoothly along the wavy trajectory, avoiding localized drying. Furthermore, the smooth transition characteristics of the wavy shape allow heat to be transferred to the solvent more evenly, thereby effectively reducing energy waste.
