Description

Technical Field

[0001] This invention relates to the field of seasoning production technology, and in particular to an ultrasonic-assisted extraction device for Sichuan pepper seasoning oil and its application. Background Technology

[0002] Sichuan peppercorn seasoning oil, a condiment with a unique flavor and wide range of uses, plays an important role in food processing, catering, and other fields. The preparation of Sichuan peppercorn seasoning oil usually begins with the processing of Sichuan peppercorn raw materials. The conventional process involves crushing dried Sichuan peppercorn raw materials into granules or coarse powder, which is then directly added to edible vegetable oil. Through heating and soaking or stirring, the volatile oil (aroma) and numbing agents (taste) in the Sichuan peppercorns are transferred to the oil phase using the solid-liquid extraction principle.

[0003] However, existing extraction equipment has many drawbacks when processing this solid-liquid mixture of peppercorns and oil.

[0004] On the one hand, traditional extraction equipment has low extraction efficiency, and the effective components in Sichuan pepper cannot be fully dissolved in the solvent, which affects the yield and quality of Sichuan pepper flavored oil. For example, in a simple soaking process, the contact area between Sichuan pepper and solvent is limited, and there is a lack of effective means to promote the dissolution of components, which makes the extraction process slow and the extraction rate low.

[0005] On the other hand, traditional extraction equipment lacks precise and flexible temperature control. The extraction process for Sichuan peppercorn oil requires a suitable temperature; excessively high temperatures may destroy some heat-sensitive components in the peppercorns, affecting the flavor and quality of the oil; excessively low temperatures will slow down the extraction process, resulting in incomplete extraction. However, traditional equipment often struggles to precisely adjust and stably control the temperature according to actual needs, making it difficult to meet the production requirements of high-quality Sichuan peppercorn oil. To address the aforementioned problems, this technical solution proposes an ultrasonic-assisted extraction device for Sichuan peppercorn flavoring oil and its application. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of low extraction efficiency and inaccurate temperature control in traditional extraction equipment, and to propose an ultrasonic-assisted extraction device for Sichuan pepper flavoring oil and its application.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An ultrasonic-assisted extraction device for Sichuan peppercorn flavoring oil includes an extraction chamber, an oil pump fixedly installed on one side of the extraction chamber, and the output end of the oil pump extending into the extraction chamber. Multiple ultrasonic components are evenly spaced on both inner walls of the extraction chamber, a heating component is installed inside the extraction chamber, and a filter component is installed at the bottom of one side of the extraction chamber. The solid-liquid mixture formed by the peppercorn raw material and edible oil is transported to the extraction box by the oil pump. Under the temperature control of the heating element, the solid-liquid mixture flows in a tortuous manner and flows through multiple ultrasonic components in sequence for multiple ultrasonic extractions. The extracted solid-liquid mixture is then filtered by the filtration component.

[0008] In one possible design, the ultrasonic component includes a trapezoidal plate fixedly mounted on the inner wall of one side of the extraction box, with two symmetrical mounting holes on the trapezoidal plate, and an ultrasonic generator fixedly mounted in the mounting holes; In this process, the solid-liquid mixture is guided by a trapezoidal plate and flows sequentially through an ultrasonic generator to achieve multiple ultrasonic extractions.

[0009] In one possible design, the heating component includes a heat-conducting frame fixedly installed inside the extraction box, with multiple guide frames evenly spaced on the inner walls of both sides of the heat-conducting frame, and the guide frames located between two adjacent trapezoidal plates; The guide frame and the trapezoidal plate together guide the solid-liquid mixture to flow in a curved manner.

[0010] In one possible design, a first electric heating frame located inside a heat-conducting frame is fixedly installed inside the extraction box, and a water pump is fixedly installed on the top side of the extraction box, with the output end of the water pump extending into the heat-conducting frame. The water pump delivers water to the heat-conducting frame, and the first electric heating frame heats the water, thereby raising the temperature of the heat-conducting frame to control the temperature of the solid-liquid mixture.

[0011] In one possible design, heating boxes are fixedly installed on both sides of the extraction box, a second electric heating frame is fixedly installed inside the heating box, and a diversion pipe is fixedly installed on the bottom of one side of the guide frame. One end of the diversion pipe passes through the inner wall of the bottom of one side of the extraction box and extends into the heating box. In this process, water is distributed to the heating chamber through a diversion pipe, and the second electric heating rack heats the water, raising the temperature of the side wall of the extraction chamber.

[0012] In one possible design, an electronic drain valve is fixedly installed on the bottom inner wall of the heating box, with the bottom end of the electronic drain valve extending to the bottom of the heating box. The electronic drain valve is used to drain the water from the heating tank.

[0013] In one possible design, a first drain pipe is fixedly installed through the top inner wall of one side of the first heating rack. The bottom end of the first drain pipe extends to the outside of the extraction box and is fixedly installed with a flow box. A second drain pipe is fixedly installed on the top inner wall of one side of the heating box. The bottom end of the second drain pipe extends into the flow box and is fixedly connected to the bottom inner wall of one side of the flow box. A connecting pipe is fixedly installed on the inner wall of the other side of the flow box. One end of the connecting pipe extends to the outside of the flow box. The first and second drain pipes guide hot water into the flow tank, and the hot water is recycled through the connecting pipe.

[0014] In one possible design, the filtering component includes a filter box fixedly installed at the bottom of the other side of the extraction box. A discharge pipe is fixedly installed on the inner top wall of the filter box, and the top end of the discharge pipe extends into the extraction box. A cover plate is provided at the opening of the filter box to close the filter box. Four mounting rods are symmetrically fixedly installed on one side of the cover plate. A docking ring is fixedly installed inside the filter box. One end of each of the four mounting rods extends into the docking ring and is fixedly installed with the same filter plate. The filter plate fits against the inner wall of the docking ring. A discharge pipe is fixedly installed through the cover plate. A solenoid valve is fixedly installed on one side of the inner wall of the filter box, and one side of the solenoid valve extends into the extraction box. The solid-liquid mixture flows into the filter box through the discharge pipe, is filtered by the filter plate, and is discharged through the discharge pipe.

[0015] In one possible design, the top and bottom of the cover plate are fixedly mounted with clamping plates, and the top and bottom of the filter box are fixedly mounted with fixing plates. An installation shaft is fixedly mounted on one side of the fixing plate. A through hole is opened on the clamping plate, and the installation shaft passes through the through hole. A retaining strip located on one side of the clamping plate is rotatably sleeved on the installation shaft, and the retaining strip fits tightly against one side of the clamping plate. An electric push rod is fixedly mounted on the other side of the filter box. The output shaft of the electric push rod extends into the filter box and is fixedly mounted with a pressure plate. The pressure plate slides tightly against the inner wall of the filter box. The clips are used to fix the cover plate, and the electric push rod drives the pressure plate to filter impurities, thereby increasing the amount of Sichuan peppercorn seasoning oil collected.

[0016] An application of an ultrasonic-assisted extraction device for Sichuan peppercorn flavored oil, comprising the ultrasonic-assisted extraction device for Sichuan peppercorn flavored oil as described above, including the following steps: S1: Raw material preparation: The dried Sichuan pepper raw material is pulverized to obtain coarse Sichuan pepper powder or granules; S2: Feeding and extraction: The pepper granules obtained in step S1 are mixed with edible vegetable oil and pumped into the extraction tank through the oil pump (9); S3: Ultrasonic enhancement: The solid-liquid mixture flows in a tortuous manner in the extraction chamber. When it flows through the ultrasonic generator, the ultrasonic cavitation effect is used to destroy the cell structure of the pepper particles and accelerate the dissolution of flavor substances. S4: Residue and oil separation: The mixture after extraction enters the filter box, where the pepper residue is separated by the filter plate, and the residual oil in the residue is pressed by the pressure plate to obtain the finished pepper seasoning oil.

[0017] In this application, during use, the suction end of the water pump is first connected to the external water supply pipe, and the water pump is turned on. Water is then transported to the heat-conducting frame, and simultaneously, the first electric heating frame is energized to heat the water inside. The heated water raises the temperature of the heat-conducting frame. At the same time, the water is distributed to two heating chambers through multiple distribution pipes. Then, the two second electric heating frames are energized to heat the water in the heating chambers, raising the temperature of the walls on both sides of the extraction chamber. This achieves temperature regulation within the entire extraction chamber, ensuring that the solid-liquid mixture formed by the peppercorn raw material and edible oil is at a suitable temperature during extraction. Next, the oil pump is started to transport the solid-liquid mixture formed by the peppercorn raw material and edible oil into the extraction chamber. Guided by the trapezoidal plate and guide frame, the solid-liquid mixture formed by the peppercorn raw material and edible oil flows in a tortuous manner within the extraction chamber, sequentially passing through multiple ultrasonic generators installed on the trapezoidal plate. The ultrasonic generators... The solid-liquid mixture formed by the peppercorn raw material and edible oil undergoes multiple ultrasonic extraction processes to ensure more thorough extraction of the peppercorn flavoring oil. After extraction, the solenoid valve is opened, and the solid-liquid mixture flows into the filter box through the discharge pipe. The peppercorn flavoring oil is filtered through the filter plate to remove impurities. The filtered peppercorn flavoring oil is discharged and collected through the discharge pipe. When the filter box needs cleaning, the retaining strip is rotated to separate it from the retaining plate, and the cover is removed to clean or replace the filter plate. To increase the collection volume of peppercorn flavoring oil, after filtration, the electric push rod is activated to move the pressure plate closer to the filter plate to press and filter the filtered impurities. When water needs to be drained after extraction, the electronic drain valve is opened to drain the water in the heating box. At the same time, the water in the first electric heating rack and the heating box flows into the flow box through the first drain pipe and two second drain pipes, respectively. The hot water can be continuously reused through the connecting pipe.

[0018] In this invention, an ultrasonic-assisted extraction device for Sichuan peppercorn seasoning oil, through an ultrasonic component, allows the solid-liquid mixture formed by Sichuan peppercorn raw material and edible oil to be transported into the extraction chamber. Guided by a trapezoidal plate and a heating component, the mixture flows in a tortuous manner within the extraction chamber. During this flow, the mixture passes through multiple ultrasonic generators sequentially, enabling multiple ultrasonic extraction processes to be performed on the mixture, resulting in a more thorough extraction of the Sichuan peppercorn seasoning oil. In this invention, an ultrasonic-assisted extraction device for Sichuan peppercorn seasoning oil includes a heating component. A first electric heating frame is fixedly installed inside the extraction chamber within a heat-conducting frame. A water pump is fixedly installed on the top side of the extraction chamber, with its output end extending into the heat-conducting frame. The suction end of the water pump is then connected to an external water supply pipe, allowing water to be pumped into the heat-conducting frame. The first electric heating frame is then energized to heat the water, which in turn heats the heat-conducting frame. Therefore, during the extraction of the solid-liquid mixture formed by Sichuan peppercorn raw material and edible oil, the temperature of the mixture can be controlled as needed, ensuring that the mixture is at a suitable temperature during extraction. In this invention, the ultrasonic-assisted extraction device for Sichuan peppercorn seasoning oil, through a filtration component, allows the solid-liquid mixture formed by the Sichuan peppercorn raw material and edible oil to be transported to the top of the discharge pipe. At this point, it flows into the filter box through the discharge pipe. Then, the solid-liquid mixture formed by the Sichuan peppercorn raw material and edible oil can be filtered through the filter plate to remove impurities from the Sichuan peppercorn seasoning oil. The filtered Sichuan peppercorn seasoning oil can be discharged through the discharge pipe, thus facilitating the collection of the purified Sichuan peppercorn seasoning oil. This invention utilizes ultrasonic assistance and a curved flow design to allow the solid-liquid mixture formed by Sichuan peppercorns and edible oil to flow through the ultrasonic generator multiple times, resulting in more thorough extraction and improved yield and quality. Precise temperature control prevents damage to heat-sensitive components, meeting production requirements. The filter structure facilitates cleaning and replacement, and pressure filtration increases the collection capacity. Furthermore, it can discharge and collect hot water for continuous reuse, resulting in significant overall benefits. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In one embodiment: Refer to Figure 1-9 An extraction apparatus includes an extraction tank 1. An oil pump 9 is fixedly installed on one side of the extraction tank 1, and the output end of the oil pump 9 extends into the extraction tank 1. Multiple ultrasonic components are installed at equal intervals on the inner walls of both sides of the extraction tank 1. Each ultrasonic component includes a trapezoidal plate 2 fixed to the inner wall of one side of the extraction tank 1, with two symmetrical mounting holes on the trapezoidal plate 2. An ultrasonic generator 3 is fixedly installed in each mounting hole. A heating component is installed inside the extraction tank 1. The heating component includes a heat-conducting frame 4 fixed inside the extraction tank 1. Multiple guide frames 5 are equally spaced on the inner walls of both sides of the heat-conducting frame 4, with each guide frame 5 located between two adjacent trapezoidal plates 2. A first electric heating frame 6 is fixedly installed inside the heat-conducting frame 4 inside the extraction tank 1. A water pump 7 is fixedly installed on the top of one side of the extraction tank 1, and the output end of the water pump 7 extends into the heat-conducting frame 4.

[0023] like Figure 5As shown, in use, the suction end of the water pump 7 is connected to the external water supply pipe, and the water pump 7 is turned on. Water is delivered to the heat-conducting frame 4, and at the same time, the first electric heating frame 6 is energized to heat the water in the heat-conducting frame 4. The heated water causes the heat-conducting frame 4 to heat up. The water is distributed and delivered to two heating boxes 11 through multiple diversion pipes 10. The two heating boxes 11 are fixedly installed on both sides of the extraction box 1. The second electric heating frame 12 is fixedly installed in the heating box 11. The two second electric heating frames 12 are energized to heat the water in the heating box 11, raising the temperature of the walls on both sides of the extraction box 1. This achieves temperature regulation within the entire extraction box 1, ensuring that the solid-liquid mixture formed by the peppercorn raw material and edible oil is at a suitable temperature during extraction.

[0024] Start the oil pump 9 (a pump capable of transporting particulate media, such as a single screw pump) to transport the solid-liquid mixture formed by the pepper raw material and edible oil into the extraction box 1. Under the guidance of the trapezoidal plate 2 and the guide frame 5, the solid-liquid mixture formed by the pepper raw material and edible oil flows in a tortuous manner in the extraction box 1, and flows through multiple ultrasonic generators 3 installed on the trapezoidal plate 2 in sequence. The ultrasonic generators 3 perform multiple ultrasonic extraction treatments on the solid-liquid mixture formed by the pepper raw material and edible oil (the ultrasonic waves act directly on the pepper particles suspended in the oil, and the cavitation effect instantly destroys the cell walls on the surface of the particles, so that the internal numbing agents and volatile oils are quickly released into the high-temperature oil, realizing dynamic ultrasonic extraction), so that the pepper seasoning oil is extracted more fully.

[0025] like Figure 5 As shown, after extraction, the mixed fluid containing the completely extracted pepper residue flows into the filter box 18 through the discharge pipe 17. The filter box 18 is fixedly installed at the bottom of the other side of the extraction box 1, and the discharge pipe 17 is fixedly installed on the inner wall of the top of the filter box 18, with the top end of the discharge pipe 17 extending into the extraction box 1. A cover plate 20 is provided at the opening of the filter box 18 to close the filter box 18. Four mounting rods 22 are symmetrically fixedly installed on one side of the cover plate 20. A docking ring 19 is fixedly installed inside the filter box 18. One end of each of the four mounting rods 22 extends into the docking ring 19 and is fixedly installed with the same filter plate 23. The filter plate 23 fits against the inner wall of the docking ring 19. The discharge pipe 21 is fixedly installed through the cover plate 20. The Sichuan peppercorn seasoning oil is filtered through filter plate 23 to remove impurities. The filtered Sichuan peppercorn seasoning oil is discharged and collected through discharge pipe 21. After the Sichuan peppercorn seasoning oil extraction is completed, the solenoid valve 31 is opened to discharge the Sichuan peppercorn seasoning oil that cannot be discharged in the extraction box 1 into the filter box 18, thereby facilitating the filtration of the Sichuan peppercorn seasoning oil.

[0026] When cleaning the filter box 18 is required, rotate the retaining strip 26 to separate it from the retaining plate 27. The retaining plate 27 is fixedly installed at both the top and bottom of the cover plate 20, and the fixing plate 24 is fixedly installed at both the top and bottom of the filter box 18. A mounting shaft 25 is fixedly installed on one side of the fixing plate 24. A through hole 28 is formed in the retaining plate 27, through which the mounting shaft 25 passes. The retaining strip 26, located on one side of the retaining plate 27, is rotatably fitted onto the mounting shaft 25, ensuring a tight fit between the retaining strip 26 and the side of the retaining plate 27. Removing the cover plate 20 allows for cleaning or replacement of the filter plate 23.

[0027] To increase the amount of Sichuan peppercorn seasoning oil collected, after filtration, start the electric push rod 29 to move the pressure plate 30 closer to the filter plate 23. The pressure plate 30 slides tightly against the inner wall of the filter box 18 to press and filter the impurities.

[0028] This application can be used in the field of seasoning production technology, or in other fields applicable to this application.

The structure of this embodiment is basically the same as the previous embodiments, except that: when water needs to be drained after extraction, the electronic drain valve 13 is opened to drain the water in the heating box 11. The electronic drain valve 13 is fixedly installed on the bottom inner wall of the heating box 11, and its bottom end extends to the bottom of the heating box 11. Meanwhile, water in the first heating frame 6 flows into the flow box 15 through the first drain pipe 8, and water in the two heating boxes 11 flows into the flow box 15 through the two second drain pipes 14. The first drain pipe 8 is fixedly installed on the top inner wall of one side of the first heating frame 6, and its bottom end extends to the outside of the extraction box 1 and is fixedly installed in the flow box 15. The second drain pipe 14 is fixedly installed on the top inner wall of one side of the heating box 11, and its bottom end extends into the flow box 15 and is fixedly connected to the bottom inner wall of one side of the flow box 15. A connecting pipe 16 is fixedly installed on the inner wall of the other side of the flow box 15, and one end of the connecting pipe 16 extends to the outside of the flow box 15. The hot water can be continuously used through the connecting pipe 16.
