[0002] In the industrial production of flavor-oriented condiments (such as pepper water and compound spice oil), in order to completely retain the complex flavor components of plant raw materials, a process system of crushing pretreatment combined with solvent extraction is usually adopted. After increasing the specific surface area of ​​the material through mechanical crushing, the gradient temperature control soaking technology is used to promote the migration of fat-soluble flavor substances to the solvent phase, and then the flavor oil is enriched and purified through the distillation process. In this process, the efficient separation of the extract and the solid residue is the core process node, and its separation effect directly affects the operating stability of the distillation system and the quality of the product. At present, mainstream production lines are generally equipped with a solid-liquid separation system consisting of a centrifuge unit and a filter device. This technical solution occupies a dominant position in small and medium-scale production scenarios.

[0003] The oil-residue separation equipment of existing extraction equipment has shortcomings. The filtering device is limited by the filter structure design problem. Under continuous operation conditions, the separation efficiency will gradually decay with the increase of working time. Traditional equipment is limited by the structural design and cannot achieve dynamic and continuous separation of mixed oil and residue in the extraction tank.

[0022] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] Embodiment 1

[0024] See also Figures 1 to 10 As shown, a condiment processing and extraction device includes: an extraction mechanism 1 for immersion extraction, a first filtering mechanism 2 for separating mixed oil from coarse residue, a second filtering mechanism 3 for separating mixed oil from fine residue, a slag discharge mechanism 4 for removing coarse residue and a solvent recovery mechanism 5 for separating solvent and condiment.

[0025] The extraction mechanism 1 includes an extraction tank 11, a stirring rod 12, a first drive motor 13 and a control valve block 14. The stirring rod 12 is rotatably disposed in the extraction tank 11, and the first drive motor 13 is connected to the stirring rod 12, that is, the first drive motor 13 can drive the stirring rod 12 to rotate in the extraction tank 11, thereby stirring the raw material and the solvent in the extraction tank 11.

[0026] The control valve block 14 is arranged at the discharge port at the lower end of the extraction tank 11. It should be noted that in the present embodiment, the control valve block 14 has the same number of liquid outlets as the first filtering mechanism 2, and the liquid outlets are connected to the corresponding first filtering mechanism 2 through pipelines. It can be understood that the control valve block 14 can control the mixed oil and residue in the extraction mechanism 1 to enter the selected first filtering mechanism 2.

[0027] The first filtering mechanism 2 includes a housing 21 , a first telescopic rod 22 , a pressing plate 23 , a liquid inlet assembly 24 , a combined filter screen 25 , a second telescopic rod 26 and a baffle 27 .

[0028] It should be noted that, in this embodiment, there are six first filtering mechanisms 2 .

[0029] The housing 21 is connected to the second filter mechanism 3, and the pressing plate 23 is connected to the upper end of the housing 21 through the first telescopic rod 22. It can be understood that the extension of the first telescopic rod 22 can make the pressing plate 23 rise, and the shortening of the first telescopic rod 22 can drive the pressing plate 23 to fall, until the lower end surface of the pressing plate 23 is squeezed and matched with the upper end surface of the housing 21, so as to prevent the mixed oil and material residue in the housing 21 from leaking out of the first filter mechanism 2 from the pressing plate 23. Specifically, a slide groove 232 is also provided on the pressing plate 23, and the liquid inlet component 24 is slidably provided in the slide groove 232. In this embodiment, a rubber sealing strip is also provided in the slide groove 232 to prevent the mixed oil, material residue, etc. from leaking out of the first filter mechanism 2 from the slide groove 232.

[0030] The liquid inlet assembly 24 is slidably mounted on the pressure plate 23, the liquid inlet assembly 24 is connected to the control valve block 14 through a pipeline, and the combined filter screen 25 is connected to the lower end of the liquid inlet assembly 24. Specifically, the combined filter screen 25 includes a first filter screen 251 and a second filter screen 252, the first filter screen 251 is a hemispherical filter screen, and the first filter screen 251 is fixedly connected to the second filter screen 252. Correspondingly, the second filter screen 252 is slidably matched with the inner wall of the housing 21.

[0031] The liquid inlet assembly 24 includes a liquid inlet pipe 241, a liquid outlet 242, a connecting sleeve 243, a liquid outlet hole 244 and a partition 245. The liquid inlet pipe 241 is connected to the control valve block 14 through a pipeline, the liquid outlet 242 is arranged at the lower end of the liquid inlet pipe 241, the connecting sleeve 243 is fixedly connected to the lower end of the liquid inlet pipe 241, the liquid outlet hole 244 is arranged on the connecting sleeve 243, and correspondingly, the lower end of the connecting sleeve 243 is fixedly connected to the first filter screen 251 of the combined filter screen 25. It can be understood that the mixed oil and residue enter the liquid inlet pipe 241 through the pipeline, and are sprayed to the upper end of the first filter screen 251, that is, the concave side of the first filter screen 251, through the liquid outlet 242. Part of the mixed oil and fine residue pass through the first filter screen 251 and fall into the second filter mechanism 3; part of the mixed oil, that is, the coarse residue and fine residue flow to the top of the second filter screen 252 through the liquid outlet hole 244 on the connecting sleeve 243 under impact, among which the mixed oil and fine residue pass through the second filter screen 252 and fall into the second filter mechanism 3, and the coarse residue accumulates above the second filter screen 252, and as it accumulates, it pushes the liquid inlet component 24 and the combined filter screen 25 to slide downward along the inner wall of the outer shell 21. Specifically, the liquid inlet assembly 24 also includes a first spring 249, and the upper end of the liquid inlet pipe 241 is connected to the pressure plate 23 through the first spring 249. It should be noted that when the first spring 249 releases its elastic force and contracts, it can drive the liquid inlet assembly 24 and the combined filter screen 25 to slide upward, thereby accelerating the mixed oil and fine residue to pass through the combined filter screen 25.

[0032] It should be noted that the mixed oil and the residue are directly sprayed from the liquid outlet 242 to the concave side of the first filter screen 251, which can not only separate part of the mixed oil, fine residue and coarse residue, but also prevent the residue from accumulating on the concave side of the first filter screen 251 and causing blockage. The partition 245 is fixedly connected to the outer wall of the liquid inlet pipe 241, and correspondingly, the partition 245 is located above the combined filter screen 25, and the two sides of the partition 245 are slidably matched with the inner wall of the shell 21. It can be understood that the coarse residue accumulated above the combined filter screen 25 will be divided into two parts by the partition 245.

[0033] The liquid inlet assembly 24 also includes an air supply pipe 246, an air hole 247 and an air inlet valve 248. The air supply pipe 246 is fixedly connected to the partition 245, and the air hole 247 is provided at the lower end of the air supply pipe 246, and the air inlet valve 248 is provided at the upper end of the air supply pipe 246. It should be noted that the air inlet valve 248 can be provided at the upper end of the air supply pipe 246, and the air supply equipment can be connected through a pipeline. When producing easily oxidizable products or using easily oxidizable solvents, nitrogen can be introduced into the air supply pipe 246 using the air supply equipment. In this embodiment, air enters the air supply pipe 246 through the air inlet valve 248, and enters the first filter mechanism 2 through the air hole 247 below the air supply pipe 246. It should be noted that, in this embodiment, the rotating shell 32 of the second filter mechanism 3 and the guide plate 321 on the rotating shell 32 rotate to make the gas flow downward, and the air supply pipe 246 can cooperate with the second filter mechanism 3 to generate a downward airflow in the first filter mechanism 2 and the second filter mechanism 3, thereby accelerating the mixed oil and fine residue to pass through the combined filter screen 25.

[0034] The baffle 27 is installed in the housing 21 through the second telescopic rod 26. It should be noted that the extension of the second telescopic rod 26 can drive the baffle 27 to rise, so that the baffle 27 is squeezed and matched with the lower part of the second filter 252 in the combined filter 25, and the second telescopic rod 26 continues to extend, which can further push the baffle 27, the combined filter 25, and the liquid inlet assembly 24 to slide upward, compressing the slag between the combined filter 25 and the pressing plate 23, so as to further squeeze out the mixed oil in the slag.

[0035] It should be noted that the pressing plate 23 is also provided with a locking mechanism 231, and the locking mechanism 231 includes a bracket 2311, an electromagnet 2312, and a second spring 2313. The bracket 2311 is slidably arranged on the pressing plate 23, and the electromagnet 2312 is fixedly connected to a side of the bracket 2311 close to the liquid inlet assembly 24. The bracket 2311 is connected to the pressing plate 23 via the second spring 2313. It can be understood that the electromagnet 2312 is squeezed and matched with the pressing plate 23, and the liquid inlet assembly 24 can be locked, so that the liquid inlet assembly 24 cannot slide in the slide groove 232. It should be noted that the locking mechanism 231 cooperates with the liquid inlet assembly 24. After locking the liquid inlet assembly 24, the first telescopic rod 22 extends, which can drive the pressure plate 23, the liquid inlet assembly 24, the combined filter screen 25, and the slag between the pressure plate 23 and the combined filter screen 25 to slide upward together, rising until the combined filter screen 25 just does not slide out of the outer shell 21. Under the separation of the partition 245, the slag will flip outward from both sides of the partition 245 or slide into the slag discharge mechanism 4.

[0036] The second filtering mechanism 3 includes a fixed shell 31, a rotating shell 32, a rotating connector 33 and a second driving motor 34. The fixed shell 31 is provided with a second slag discharge port 311, the rotating shell 32 is rotatably arranged on the fixed shell 31, and the rotating connector 33 is arranged below the rotating shell 32. Specifically, a guide plate 321 is fixedly arranged on the inner wall of the rotating shell 32. The second driving motor 34 cooperates with the rotating shell 32, and the rotating connector 33 is connected to the solvent recovery mechanism 5 through a pipeline. It can be understood that the second driving motor 34 drives the rotating shell 32 and the guide plate 321 to rotate, which can drive the mixed oil and fine slag falling into the second filtering mechanism 3 to rotate. The fine slag will move toward the second slag discharge port 311 of the fixed shell 31 under the action of centrifugal force, and be discharged through the second slag discharge port 311. The mixed oil enters the solvent recovery mechanism 5 through the rotating connector 33 and the pipeline at the bottom of the rotating shell 32.

[0037] The slag discharge mechanism 4 is installed on the first filtering mechanism 2. Specifically, the slag discharge mechanism 4 includes a slag discharge trough 41, an annular conveyor belt 42 and a first slag discharge port 43, the slag discharge trough 41 is arranged outside the first filtering mechanism 2, the annular conveyor belt 42 is arranged at the bottom of the slag discharge trough 41, and the slag discharge trough 41 is provided with a first slag discharge port 43.

[0038] The solvent recovery mechanism 5 includes an evaporation reactor 51 and a solvent storage tank 52. The evaporation reactor 51 is connected to the second filtering mechanism 3 through a pipeline. The evaporation reactor 51 is connected to the solvent storage tank 52 through a pipeline. The solvent storage tank 52 is connected to the extraction mechanism 1 through a pipeline.

[0039] The working principle of the present invention is as follows: The seasoning raw materials and the solvent are put into the extraction tank 11 , and the stirring rod 12 rotates in the extraction tank 11 to stir the raw materials and the solvent in the extraction tank 11 to accelerate the soaking and extraction of the raw materials. The mixed oil and the residue produced after the soaking and extraction are completed enter the control valve block 14 .

[0040] The control valve block 14 controls the mixed oil and the residue to enter the three first filter mechanisms 2 first. After a lot of residue accumulates in the outer shell 21 of this part of the first filter mechanism 2, the control valve block 14 automatically switches to control the mixed oil and the residue to enter the other three first filter mechanisms 2, thereby realizing dynamic continuous separation.

[0041] The mixed oil and the residue enter the liquid inlet pipe 241 through the pipeline, and are sprayed to the upper end of the first filter screen 251, that is, the concave side of the first filter screen 251, through the liquid outlet 242. Part of the mixed oil and the fine residue pass through the first filter screen 251 and fall into the second filter mechanism 3. Another part of the mixed oil, that is, the coarse residue and the fine residue, flows to the top of the second filter screen 252 through the liquid outlet 244 on the connecting sleeve 243 under impact, wherein the mixed oil and the fine residue pass through the second filter screen 252 and fall into the second filter mechanism 3, and the coarse residue accumulates above the second filter screen 252, and as it accumulates, it pushes the liquid inlet component 24 and the combined filter screen 25 to slide downward along the inner wall of the housing 21. At the same time, the air supply pipe 246 provided on the liquid inlet component 24 can cooperate with the second filter mechanism 3 to generate a downward airflow in the first filter mechanism 2 and the second filter mechanism 3, accelerating the mixed oil and the fine residue to pass through the combined filter screen 25.

[0042] After a large amount of residue accumulates in the first filtering mechanism 2, the extension of the second telescopic rod 26 can drive the baffle 27 to rise, so that the baffle 27 is squeezed and matched with the bottom of the second filter 252 in the combined filter 25. The second telescopic rod 26 continues to extend, which can further push the baffle 27, the combined filter 25, and the liquid inlet assembly 24 to slide upward, compressing the residue between the combined filter 25 and the pressure plate 23, so as to further squeeze out the mixed oil in the residue.

[0043] Afterwards, the locking mechanism 231 cooperates with the liquid inlet component 24. After locking the liquid inlet component 24, the first telescopic rod 22 extends, which can drive the pressure plate 23, the liquid inlet component 24, the combined filter screen 25, and the slag between the pressure plate 23 and the combined filter screen 25 to slide upward together, rising until the combined filter screen 25 just does not slide out of the outer shell 21. Under the separation of the partition 245, the slag will flip outward from both sides of the partition 245 or slide into the slag discharge mechanism 4, and be discharged from the equipment through the slag discharge mechanism 4.

[0044] The second driving motor 34 drives the rotating shell 32 and the guide plate 321 to rotate, which can drive the mixed oil and fine slag falling into the second filtering mechanism 3 to rotate. The fine slag will move toward the second slag discharge port 311 of the fixed shell 31 under the action of centrifugal force and be discharged through the second slag discharge port 311. The mixed oil enters the solvent recovery mechanism 5 through the rotating connector 33 and the pipeline at the bottom of the rotating shell 32.

[0045] After the mixed oil enters the evaporation reactor 51, it is heated and evaporated to separate the solvent from the feed oil. The solvent enters the solvent storage tank 52, and the product feed oil is discharged from the equipment through a pipeline.
