Description

Technical Field

[0001] This utility model relates to the field of fragrance extraction technology, specifically a fragrance extract impurity adsorption and filtration device. Background Technology

[0002] Fragrance extracts (such as essential oils, tinctures, resins, etc.) are widely used in the food, cosmetics and pharmaceutical industries, but their production process often contains multiple components such as plant tissue fragments, colloids, pigments, hydrophilic / hydrophobic impurities, which seriously affect the purity and stability of the products.

[0003] Traditional filtration devices often employ a single filter media or a simple series structure, which has significant drawbacks: low filtration efficiency; conventional devices cannot classify impurities with significantly different physicochemical properties in fragrance extracts; when hydrophilic impurities (such as polyphenols and proteins) coexist with hydrophobic impurities (such as waxes and terpene polymers), the adsorption selectivity of a single filter media is poor, resulting in high impurity penetration or over-adsorption of active ingredients; filter media compaction and channeling occur when the feed liquid directly impacts the filter media surface, and excessively high local flow velocities can easily form a channeling effect, failing to fully utilize the filter layer; at the same time, the kinetic energy of droplets compacts the filter media (especially the fine particulate layer), accelerating cake formation, clogging the flow channels, and significantly shortening the filtration cycle. Utility Model Content

[0004] The purpose of this invention is to provide a fragrance extract impurity adsorption and filtration device, which has the effects of gradient adsorption for efficient purification, and shock-resistant liquid distribution to prevent clogging.

[0019] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0020] Please see Figures 1-5 In this embodiment of the present invention, a fragrance extract impurity adsorption and filtration device includes three interlocking cylinders 1. The top of the uppermost cylinder 1 is provided with a sealing cap 2, which is fixedly connected to the top of the uppermost cylinder 1 by fixing screws, allowing for quick assembly and disassembly. A feed pipe 201 is fixedly provided in the middle of the sealing cap 2, and a distribution plate is provided at the outlet end of the feed pipe 201. Liquid entering from the feed pipe 201 first impacts the distribution plate, being dispersed into multiple fine streams, which are evenly sprayed onto the entire cross-section of the uppermost filter material 302, avoiding localized impact that could cause channeling or compaction of the filter material 302. A flow guide shroud 102 is fixedly provided at the bottom of each cylinder 1. This shroud is designed as an inverted cone to collect the liquid flowing out from the previous stage and guide the liquid to flow evenly to the next stage, preventing short-circuiting along the cylinder wall of the cylinder 1 and preventing direct dripping of liquid onto the surface of the next stage filter material 302, thus avoiding localized compaction that could form a sludge cake and cause blockage. A filter cylinder 3 is provided inside each cylinder 1. The bottom of the filter cartridge 3 is provided with a through hole. The interior of the filter cartridge 3 is filled with filter media 302. The uppermost filter media 302 is an inert material with large pore size and high porosity, such as food-grade porous ceramic balls, coarse diatomaceous earth particles, or large pore size sintered metal particles, which intercepts larger solid particles and some plant tissue fragments. The middle filter media 302 is an adsorbent with medium pore size and strong hydrophilicity, such as modified zeolite, food-grade activated alumina or kaolin particles with a specific pore size range, which mainly adsorbs hydrophilic impurities in the fragrance extract. The lowermost filter media 302 is an adsorbent with smaller pore size and specific hydrophobicity / weak polarity, such as surface-silanized activated alumina, specific type of hydrophobic polymer adsorption resin particles, or specially treated activated carbon, which mainly adsorbs hydrophobic or weakly polar impurities. The filter cartridge 3 is provided with an inner filter cloth or filter bag, which can wrap the filter media 302 to prevent particle leakage. The three-level gradient structure can use different filter media 302 to perform adsorption and filtration in a gradient manner.

[0021] In this embodiment, preferably, the bottom of the two upper cylinders 1 is fixedly provided with a positioning disk 105, the surface of which is provided with a positioning groove 106, and the top of the two lower cylinders 1 is fixedly provided with a positioning disk 107, the upper surface of which is provided with a positioning post 108 that cooperates with the positioning groove 106. The cooperation between the positioning groove 106 and the positioning post 108 enables the adjacent cylinders 1 to be quickly assembled and also facilitates separation.

[0022] In this embodiment, preferably, the tops of the two lower cylinders 1 are each fitted with a sealing ring 104, so that the adjacent cylinders 1 are assembled together to ensure sealing. A handle 103 is fixedly provided on the outside of the cylinder 1, and the upper cylinder 1 can be disassembled using the handle 103.

[0023] In this embodiment, preferably, the liquid distribution plate includes multiple liquid distribution pipes 203. The outer liquid distribution pipes 203 are fixedly connected to the inner side of the sealing cover 2 via mounting posts 202. The bottom of each liquid distribution pipe 203 is provided with uniformly arranged nozzles 204. Adjacent liquid distribution pipes 203 are connected by a connecting pipe 205. A connecting plate 206 connected to the feed pipe 201 is fixedly provided in the middle of the connecting pipe 205. When liquid enters from the feed pipe 201, it first impacts the liquid distribution pipes 203 and is dispersed into multiple fine streams. These streams are then uniformly sprayed onto the entire cross-section of the uppermost filter material 302 through the nozzles 204, thus avoiding local impact that could cause channeling or compaction of the filter material 302.

[0024] In this embodiment, preferably, the inner wall of the cylinder 1 is fixedly provided with an annular support strip 101 to support the filter cartridge 3, and the top of the filter cartridge 3 is provided with a handle 301, which can remove the filter cartridge 3 from the inside of the cylinder 1 and replace the filter material 302 inside.

[0025] In this embodiment, preferably, a baffle 4 is fixedly provided at the bottom end of the lowest flow guide shroud 102 to prevent splashing or eddy currents from introducing air when the liquid flows out. A drain pipe 401 is fixedly provided in the middle of the baffle 4, and a drain valve 402 is provided in the middle of the drain pipe 401.

[0026] In this embodiment, preferably, a support column 109 is fixedly provided at the bottom of the lowest cylindrical body 1, and an anti-slip pad is provided at the bottom end of the support column 109 to provide stable support for the entire device.

[0027] In use, the spice extract to be processed enters the device through the feed pipe 201, first impacting the connecting plate 206 of the distribution plate. The liquid is then distributed through multiple connecting pipes 205 to the annularly arranged distribution pipes 203, and finally forms multiple low-pressure fine streams through evenly distributed nozzles 204, uniformly covering the surface of the filter media 302 in the uppermost filter cartridge 3, completely avoiding channeling or compaction of the filter media caused by local jet impact. The liquid penetrates into the uppermost filter media 302 (a layer of large-pore inert material), where porous ceramic balls or coarse-grained diatomaceous earth trap large particles of impurities such as plant tissue fragments and colloids. After filtration, the liquid flows through the bottom through-hole of the filter cartridge 3 into the inverted conical guide hood 102. The conical structure of the guide hood 102 guides the liquid to converge towards the center, preventing short-circuit flow along the inner wall of the cartridge 1 and ensuring that the liquid flows smoothly into the surface of the middle filter media 302, eliminating drip impact. The liquid enters the middle filter media 3... 02 (Hydrophilic adsorbent layer): Modified zeolite or activated alumina targets and adsorbs hydrophilic impurities such as polyphenols and proteins through ion exchange and pore size sieving. The inner lining of the filter cloth or filter bag prevents the adsorbent particles from leaking with the liquid flow. When the liquid reaches the bottom filter material 302 (hydrophobic adsorbent layer), silanized activated alumina or polymer resin selectively adsorbs weakly polar impurities such as waxes and terpene polymers by relying on hydrophobic forces. The purified liquid is collected by the bottom guide hood 102, and after hitting the baffle 4 to eliminate splashing and eddies, it is output controllably from the drain pipe 401 through the drain valve 402. The handle 301 can be used to directly lift the filter cartridge 3, replace the single-stage filter material 302, and hold the handle 103 to lift the cartridge 1 upwards, so that the positioning groove 106 of the positioning disk one 105 is separated from the positioning column 108 of the positioning disk two 107. With the help of the sealing ring 104, rapid separation and sealing recombination are achieved.

[0028] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
