Description

Technical Field

[0001] This utility model belongs to the field of chili extraction technology, and in particular relates to a continuous extraction device for extracting chili oil resin. Background Technology

[0002] In the field of capsicum oleoresin extraction, traditional extraction methods and equipment have many limitations. Early static extraction methods involved simply mixing the capsicum raw material with a solvent and then letting it stand. Due to the lack of effective stirring or dynamic mixing mechanisms, the contact between the solvent and the capsicum particles relied solely on natural diffusion. This resulted in an extremely slow rate of capsicum oleoresin dissolution from the capsicum cells, often requiring a significant amount of time and severely impacting production efficiency. For example, in some small-scale workshops, a single extraction could take several hours or even days, failing to meet the demands of large-scale industrial production for high efficiency and speed.

[0003] With technological advancements, some equipment has incorporated stirring devices to promote mixing between solvents and raw materials. However, this type of stirring often results in uneven mixing, preventing some chili pepper raw materials from fully contacting the solvent and creating extraction dead zones, leading to unsatisfactory chili oleoresin extraction rates. Furthermore, if the mechanical shear forces generated during stirring are not properly controlled, they may excessively damage the cell structure of the chili pepper raw materials, introducing too many impurities and increasing the difficulty of subsequent separation and purification.

[0004] In addition, some existing continuous extraction devices are not structurally sound. For example, some devices lack coordination in raw material input and solvent circulation, making it impossible to efficiently recycle the solvent within the device, resulting in solvent waste. At the same time, it is difficult to ensure the relative stability of the solvent concentration throughout the extraction process, affecting the consistency of chili oil resin extraction and the stability of product quality.

[0005] Therefore, it is essential to invent a continuous extraction device for extracting chili oil resin. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a continuous extraction device for extracting chili oil resin, comprising an extraction tank, an extraction auxiliary device, a top cover, support legs, an injection port, a discharge port, a support frame, hydraulic cylinders, an ultrasonic generator, and an ultrasonic bar. The extraction auxiliary device, installed inside the extraction tank, is fixed to the top cover, which is also fixedly installed inside the extraction tank. A support leg is fixedly installed below the extraction tank, with an injection port and a discharge port respectively located at the top and bottom of one side. A support frame is fixedly installed above the extraction tank, and hydraulic cylinders are fixedly installed at the bottom of the extraction tank and above the support frame. The output ends of two opposing hydraulic cylinders are connected to the extraction auxiliary device. An ultrasonic generator, fixedly installed outside the extraction tank, is connected to the ultrasonic bar installed inside.

[0007] Preferably, the extraction auxiliary device includes an isolation filter cylinder, a slide rail, an upper extrusion plate, a lower extrusion plate, ball heads, and a connecting rod. The bottom of the isolation filter cylinder is fixedly connected to the bottom of the interior of the extraction tank, and its top is fixedly passed through the top cover. The isolation filter cylinder is slidably connected to the upper extrusion plate and the lower extrusion plate through the slide rail provided inside. Ball heads are evenly distributed on the surface of the upper extrusion plate and the lower extrusion plate, and both are connected to the output end of the corresponding hydraulic cylinder through the connecting rod.

[0008] Preferably, the isolation filter cartridge is a cylindrical filter cartridge structure composed of several arc-shaped filter plates. The chili raw material can be put into the isolation filter cartridge through the opening at the top. The isolation filter cartridge is vertically installed in the middle of the inside of the circular extraction tank.

[0009] Preferably, there is an annular space between the extraction tank and the isolation filter cartridge, and a circular array of several ultrasonic bars are arranged in the annular space between them and are located around the outside of the isolation filter cartridge.

[0010] Preferably, the insulating filter cartridge allows the upper and lower extrusion discs, which slide inside, to move vertically up and down, and the surfaces of the upper and lower extrusion discs opposite each other are provided with a number of hemispherical ball-head protrusion structures.

[0011] Preferably, the connecting rod of the upper extrusion plate is connected to the output end of a hydraulic cylinder fixedly installed above the support frame, and the connecting rod of the lower extrusion plate is connected to the output end of a hydraulic cylinder fixedly installed at the bottom of the extraction tank. The lower extrusion plate can move upward and lift the chili raw material to the opening of the isolation filter cylinder, while the upper extrusion plate can move upward and detach from the isolation filter cylinder and be positioned above the opening of the isolation filter cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes hydraulic cylinders arranged vertically to drive the upper and lower extrusion discs in a reciprocating motion within an isolation filter cartridge, enabling continuous and efficient movement of the chili raw material within the solvent. Compared to traditional static extraction, this significantly increases the contact area and frequency between the chili raw material and the solvent, accelerating the dissolution of chili oleoresin from the chili cells into the solvent, significantly shortening the extraction time, and improving production efficiency. Experimental tests have shown that, under the same conditions, extraction using this device significantly reduces the extraction time.

[0014] This utility model's isolation filter cartridge employs a cylindrical structure composed of several arc-shaped filter plates, with hemispherical protrusions on the opposing surfaces of the upper and lower extrusion discs. This design allows the device to adapt to chili raw materials of different textures and particle sizes. For harder chilies, the reciprocating extrusion of the extrusion discs and the action of the protrusions effectively disrupt their cell structure, promoting solvent penetration. For smaller chilies, the protrusions prevent raw material accumulation, ensure uniform solvent flow, avoid "channeling," and ensure that all types of chili raw materials can achieve full extraction, improving extraction rate and product quality stability.

[0015] The annular space formed between the extraction tank and the isolation filter cartridge in this invention not only provides space for solvent storage and circulation but also effectively isolates impurities in the chili raw material. During the extraction process, the solvent containing chili oleoresin can circulate within this annular area and be discharged through the outlet for subsequent processing, while preventing impurities from flowing out with the solvent and affecting subsequent processes. Moreover, the annular space, in conjunction with the extraction area within the isolation filter cartridge, helps maintain a relatively stable solvent concentration, ensuring the continuity and stability of the extraction process and improving the consistency of chili oleoresin extraction.

[0016] This invention features an upper extrusion disc that can move upwards to detach from the isolation filter cylinder, facilitating the pouring of chili raw materials into the filter cylinder; the lower extrusion disc can move upwards to lift the chili raw materials to the opening of the isolation filter cylinder. This design makes the raw material feeding operation simple and quick, and during the extraction process, the movement of the extrusion discs can be flexibly controlled as needed to achieve precise control of the extraction process.

[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] This utility model provides a continuous extraction device for extracting chili oil resin, comprising an extraction tank 1, an extraction auxiliary device 2, a top cover 3, a support leg 4, an injection port 5, a discharge port 6, a support frame 7, a hydraulic cylinder 8, an ultrasonic generator 9, and an ultrasonic rod 10. The extraction auxiliary device 2, installed inside the extraction tank 1, is fixed to the top cover 3, which is also fixedly installed inside the extraction tank 1. The support leg 4 is fixedly installed at the bottom of the extraction tank 1, with an injection port 5 and a discharge port 6 respectively located at the top and bottom of one side. The support frame 7 is fixedly installed on the top of the extraction tank 1, and hydraulic cylinders 8 are fixedly installed at the bottom of the extraction tank 1 and on top of the support frame 7. The output ends of the two opposing hydraulic cylinders 8 are connected to the extraction auxiliary device 2. The ultrasonic generator 9, fixedly installed outside the extraction tank 1, is connected to the ultrasonic rod 10 installed inside.

[0026] Furthermore, the extraction auxiliary device 2 consists of an isolation filter cylinder 21, slide rails 22, an upper extrusion plate 23, a lower extrusion plate 24, ball heads 25, and a connecting rod 26. The bottom of the isolation filter cylinder 21 is fixedly connected to the stainless steel base plate at the bottom of the extraction tank 1 by welding, and its top penetrates the top cover 3 and is fastened with bolts to ensure stability. Two stainless steel slide rails 22 are symmetrically arranged on both sides inside the isolation filter cylinder 21. The slide rails 22 form a sliding fit with the corresponding slide grooves opened on the edges of the upper extrusion plate 23 and the lower extrusion plate 24, restricting the upper and lower extrusion plates to move only in the vertical direction. The upper extrusion plate 23 and the lower extrusion plate 24 are made of high-strength aluminum alloy, and hemispherical ball heads 25 are evenly distributed on the surface. The ball heads 25 are fixed to the surface of the extrusion plate by an inlay process to enhance the contact friction with the chili raw material. The two extrusion discs are connected to the output end of the hydraulic cylinder 8 via connecting rod 26. One end of connecting rod 26 is hinged to the upper and lower extrusion discs via a pin, and the other end is threaded to the connecting seat at the end of the piston rod of the hydraulic cylinder 8, which facilitates disassembly and maintenance.

[0027] Furthermore, the isolation filter cartridge 21 is a cylindrical filter cartridge structure, composed of at least six arc-shaped stainless steel filter plates spliced ​​together. Each filter plate has a flange on its edge, and adjacent filter plates are fastened to a sealing gasket with bolts to ensure airtightness. The surface of the filter plates is evenly distributed with filter holes of 1mm in diameter, which effectively filters the chili raw material while facilitating solvent passage. The isolation filter cartridge 21 is vertically installed at the center of the circular extraction tank 1, and is fixedly connected to the stainless steel base plate at the bottom of the extraction tank 1. Its top protrudes above the top cover 3, forming an open raw material inlet, making it convenient for operators to pour the chili raw material into the filter cartridge.

[0028] Furthermore, an annular space is formed between the extraction tank 1 and the isolation filter cartridge 21, within which at least eight ultrasonic rods 10 are arranged in a ring array at equal intervals. Each ultrasonic rod 10 has a waterproof titanium alloy shell, internally encapsulating an ultrasonic transducer. Its bottom is fixed to a pre-drilled mounting hole on the inner wall of the bottom of the extraction tank 1 via a threaded connector, and its top is connected to the bottom of the top cover 3 via a snap-fit ​​bracket, ensuring the ultrasonic rod 10 is stable and level. The ultrasonic rod 10 is electrically connected to an external ultrasonic generator 9, which is connected to the ultrasonic rod 10 via a data cable passing through a pre-drilled sealing hole in the side wall of the extraction tank 1, providing it with a high-frequency oscillation signal.

[0029] Furthermore, the slide 22 inside the filter cartridge 21 precisely matches the upper extrusion plate 23 and the lower extrusion plate 24, ensuring that the two extrusion plates can make stable vertical movements inside the filter cartridge. The hemispherical ball heads 25 on the opposing surfaces of the upper extrusion plate 23 and the lower extrusion plate 24 have a diameter of 1.5cm, a protrusion height of 0.8cm, and a spacing of 3cm between the ball heads 25, forming an alternating arrangement. During the relative movement of the upper and lower extrusion plates 23 and 24, the ball heads 25 can effectively squeeze and turn the chili raw material, increase the contact area between the raw material and the solvent, and prevent the raw material from accumulating and clumping during the extrusion process.

[0030] Furthermore, the connecting rod 26 of the upper extrusion plate 23 is connected to the output end of the hydraulic cylinder 8 fixedly installed above the support frame 7. The hydraulic cylinder 8 is fixed to the mounting platform of the support frame 7 by bolts, and its piston rod end is connected to the connecting rod 26 through a threaded connector, so that the upper extrusion plate 23 can move up and down with the extension and retraction of the hydraulic cylinder 8. The connecting rod 26 of the lower extrusion plate 24 is connected to the hydraulic cylinder 8 fixedly installed at the bottom of the exterior of the extraction tank 1, and its piston rod extends upward and is hinged to the connecting rod 26. During operation, the lower extrusion plate 24 can move upward under the drive of the hydraulic cylinder 8, lifting the chili raw material in the filter cylinder to the opening of the isolation filter cylinder 21 for subsequent processing; the upper extrusion plate 23 can move upward to detach from the isolation filter cylinder 21, making room for the addition of new raw material.

[0031] The working principle is as follows: First, the upper extrusion plate 23 moves upward and separates from the isolation filter cylinder 21. The operator pours the chili raw material into the cylinder through the top opening of the isolation filter cylinder 21, and then the upper extrusion plate 23 resets. Next, the solvent is injected into the extraction tank 1 through the injection port 5, filling the annular space between the extraction tank 1 and the isolation filter cylinder 21, and seeping into the isolation filter cylinder 21 to contact the chili raw material.

[0032] Then, the upper and lower hydraulic cylinders 8 drive the upper extrusion plate 23 and the lower extrusion plate 24 to move back and forth relative to each other in the isolation filter cylinder 21. The ball head 25 on the surface of the extrusion plate flips and extrudes the chili raw material, so that it is fully mixed with the solvent, and accelerates the dissolution of chili oil resin into the solvent.

[0033] At the same time, the external ultrasonic generator 9 transmits high-frequency oscillation signals to the ultrasonic rod 10. The ultrasonic rod 10 emits ultrasonic waves in the annular space region, using cavitation and mechanical effects to destroy the chili pepper cell structure and further accelerate the leaching of chili pepper oleoresin.

[0034] During the extraction process, the solvent containing chili oil resin enters the annular space area through the filter holes of the isolation filter cylinder 21 and is finally discharged through the discharge port 6 to enter the subsequent separation and purification process. The lower extrusion plate 24 can lift the extracted chili raw material to the opening of the isolation filter cylinder 21 for discharge, and the upper extrusion plate 23 rises again to allow the addition of new raw materials, realizing continuous extraction operation.

[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
