Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to a high-pressure homogenizer for spicy red oil used in snack foods. Background Technology

[0002] Spicy chili oil, as a core seasoning ingredient in snack food processing, directly determines the flavor, taste, and quality of snack foods through its color, spiciness, aroma, and smoothness. High-pressure homogenizers, through high-pressure shearing, impact, and cavitation, can fully emulsify and homogenize the oil, capsaicin, and spice components in spicy chili oil, resulting in a smooth and uniform texture and stable flavor extraction. It is a key piece of equipment for improving the quality of spicy chili oil, making it easier to adhere to the surface of snack foods and enhancing the flavor penetration effect.

[0003] Existing high-pressure homogenizers used for processing spicy chili oil mostly employ a direct-flow feeding design and lack pre-treatment functions for the chili oil materials. In actual production, spicy chili oil typically contains solid impurities such as chili flakes, Sichuan pepper residue, chopped scallions and ginger, and spice residue. These impurities, when directly introduced into the homogenizer along with the materials, easily cause blockages in the homogenization channels, resulting in poor flow of the high-pressure oil circuit. Consequently, the homogenization pressure fluctuates and becomes unstable, significantly reducing the homogenization effect of the chili oil and leading to problems such as layering, strong particle texture, and uneven flavor. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: spicy red oil usually contains solid impurities such as chili flakes, Sichuan pepper residue, chopped scallions and ginger, and spice residue. When these impurities enter the homogenizer directly with the material, they can easily cause blockage of the homogenization channel, resulting in poor flow of high-pressure oil. This leads to fluctuations and instability in the homogenization pressure, a significant decrease in the homogenization effect of the red oil, and problems such as layering, strong particle texture, and uneven flavor. Therefore, this invention proposes a high-pressure homogenizer for specialty spicy red oil used in snack foods.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-pressure homogenizer for spicy chili oil used in snack foods includes a machine body, a high-pressure homogenizing mechanism fixedly installed at the front end of the machine body, a pressure regulating screw rotatably installed on the side of the high-pressure homogenizing mechanism, and a material cup installed at the front end of the high-pressure homogenizing mechanism through a connecting pipe. An installation ring is fixedly installed on the upper end of the material cup, and a filter screen is fixedly installed on the inner wall of the installation ring. The filter screen has a conical structure and its lower end is inside the material cup. A pretreatment cylinder is provided on the upper end of the material cup, and a pressure ring is fixedly installed on the lower end of the pretreatment cylinder. The pressure ring is installed on the upper end of the material cup through a magnetic suction assembly, and the installation ring is clamped between the pressure ring and the material cup.

[0007] As a preferred embodiment, the magnetic suction assembly includes a metal ring fixedly sleeved on the material cup and a plurality of magnetic blocks equidistantly fixedly mounted on the pressure ring. The plurality of magnetic blocks are circumferentially arranged on the pressure ring and are magnetically connected to the metal ring.

[0008] As a preferred embodiment, the mounting ring has multiple positioning holes equidistantly spaced around its circumference, and multiple positioning posts are fixedly installed equidistantly around the upper circumference of the material cup, with the multiple positioning posts respectively inserted into the multiple positioning holes.

[0009] As a preferred embodiment, a bracket is fixedly installed at the upper end of the pretreatment cylinder, a support rod is horizontally fixedly installed on the bracket, a rotating shaft is vertically rotatably installed at one end of the support rod, the lower end of the rotating shaft extends into the pretreatment cylinder and is fixedly installed with an arc-shaped scraper, the arc-shaped scraper is slidably disposed on the surface of the filter screen.

[0010] As a preferred embodiment, a drive motor is fixedly mounted on the bracket, the output shaft of the drive motor is fixedly connected to the upper end of the rotating shaft, and multiple stirring rods are horizontally fixedly mounted on the rotating shaft, all of which are located inside the pretreatment cylinder.

[0011] As a preferred embodiment, multiple mounting seats are fixedly installed equidistantly on the side wall of the material cup, and a small air pump is fixedly installed on each of the multiple mounting seats. The output ends of the multiple small air pumps are connected to gas nozzles. Multiple through holes are opened on the side wall of the material cup, and one end of the gas nozzle passes through the through hole. The gas nozzle and the through hole are sealed. One end of the gas nozzle is inclined towards the bottom of the filter screen.

[0012] As a preferred embodiment, a resistance ring is fixedly installed on the side of the high-pressure homogenizing mechanism, the axis of the pressure regulating screw coincides with the axis of the resistance ring, an adjusting block is fixedly installed at one end of the pressure regulating screw, and a limiting component for restricting the rotation of the pressure regulating screw is provided on the adjusting block.

[0013] As a preferred embodiment, the adjusting block is provided with symmetrical moving holes, and the limiting component includes a moving rod that is horizontally slidably installed in the moving holes, a rubber friction block that is fixedly installed at one end of the moving rod, and a telescopic spring that is sleeved on the moving rod. The two ends of the telescopic spring are fixedly connected to the rubber friction block and the adjusting block, respectively, and the rubber friction block is tightly fitted with the resistance ring.

[0014] As a preferred embodiment, a strip connecting rod is fixedly installed at one end of each of the two moving rods. A moving groove is vertically opened on the side of the adjusting block away from the pressure adjusting screw. Sliding blocks are symmetrically slidably installed in the moving groove. Support rods are hinged to both sliding blocks. The ends of the two support rods away from the adjusting block are hinged to the strip connecting rods.

[0015] As a preferred embodiment, pressure plates are fixedly installed on both of the support rods, and both pressure plates are provided with anti-slip textures.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. A conical filter screen is installed at the top of the mixing cup, which can completely intercept solid impurities such as chili flakes, peppercorn residue, and spice residue before the spicy red oil enters the high-pressure homogenizing mechanism. This prevents impurities from entering the homogenizing channel and causing blockage, ensuring smooth flow of the high-pressure oil circuit, solving the problems of homogenization pressure fluctuation and reduced homogenization effect, and ensuring that the red oil has a delicate texture, does not separate, and has no grainy feel.

[0017] 2. The drive motor drives the stirring rod to pre-treat and mix the red oil. At the same time, the arc-shaped scraper rotates continuously along the surface of the conical filter screen to scrape away the impurities accumulated on the filter screen in time, preventing the filter screen surface from clumping and blocking the filter holes, ensuring smooth feeding of red oil, and improving feeding efficiency and filtration continuity.

[0018] 3. Multiple small air pumps can be started simultaneously, and air is sprayed at an angle to the bottom of the conical filter screen through the gas nozzle, forming an airflow backflow effect, which blows off the fine residues adhering to the inside of the filter screen, preventing fine impurities from clogging the mesh. Combined with the scraper, it achieves double anti-clogging, and the filtration effect is not affected even after long-term continuous processing.

[0019] 4. The pretreatment cylinder is magnetically connected to the metal ring of the material cup via a magnetic block on the pressure ring. The mounting ring is stably clamped, and the positioning post and positioning hole cooperate to prevent displacement. When disassembling, simply lift the pretreatment cylinder upward to remove the filter screen. No tools or bolts are required, which greatly simplifies the filter screen cleaning and replacement process and improves equipment maintenance efficiency.

[0020] 5. The pressure regulating screw is equipped with a limit component. The rubber friction block is tightly attached to the resistance ring under the action of the telescopic spring, realizing automatic locking after adjustment. This prevents the pressure screw from rotating due to equipment vibration, ensuring stable homogeneous pressure throughout the process, resulting in more uniform emulsification and more stable flavor of the spicy red oil.

[0021] 6. By squeezing the pressure plate, the moving rod can be retracted through the support rod, causing the rubber friction block to disengage from the resistance ring. The pressure can then be adjusted by rotating the adjusting block. Releasing the pressure plate automatically resets and locks it in place. The operation is convenient and the positioning is precise, making it suitable for the homogenization process requirements of different spicy red oil formulas. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figures 1-5 A high-pressure homogenizer for spicy chili oil used in snack foods includes a machine body 1. A high-pressure homogenizing mechanism 2 is fixedly installed at the front end of the machine body 1. A pressure regulating screw 3 is rotatably installed on the side of the high-pressure homogenizing mechanism 2. A material cup 4 is installed at the front end of the high-pressure homogenizing mechanism 2 through a connecting pipe 31. An installation ring 5 is fixedly installed at the upper end of the material cup 4. A filter screen 6 is fixedly installed on the inner wall of the installation ring 5. The filter screen 6 has a conical structure and its lower end is inside the material cup 4. A pretreatment cylinder 7 is provided at the upper end of the material cup 4. A pressure ring 8 is fixedly installed at the lower end of the pretreatment cylinder 7. The pressure ring 8 is installed at the upper end of the material cup 4 through a magnetic suction assembly. The installation ring 5 is clamped between the pressure ring 8 and the material cup 4.

[0026] The main body 1 provides support and power for the entire machine. The high-pressure homogenizing mechanism 2 is a mature core component of existing homogenization, consisting of a high-pressure pump, homogenizing valve group, pressurizing chamber, and pressure relief channel. The working principle is to draw the pre-treated red oil material into the pressurizing chamber, and generate a high pressure of 10-100MPa through the high-pressure pump, causing the material to be sprayed at high speed in the narrow gap of the homogenizing valve. Utilizing the quadruple action of shearing, impact, cavitation, and turbulence, the oil, capsaicin, and spice particles are broken down to the micron level, achieving complete emulsification and homogenization, making the red oil delicate, non-layered, and with a uniform flavor. The pressure regulating screw 3 is used to precisely adjust the gap of the homogenizing valve, thereby changing the working pressure. The material cup 4 temporarily stores the filtered red oil material. The mounting ring 5 provides a fixed carrier for the filter screen 6. The conical filter screen 6 filters solid impurities from top to bottom to avoid clogging the homogenizing channel. The pre-treatment cylinder 7 provides space for stirring and scraping. The pressure ring 8, in conjunction with magnetic attraction, enables quick assembly and disassembly. The magnetic assembly enables quick docking of the pre-treatment cylinder 7 and the material cup 4 without bolts, facilitating cleaning and maintenance.

[0027] Reference Figure 6 The magnetic attraction component includes a metal ring 9 fixedly sleeved on the material cup 4 and multiple magnetic blocks 10 equidistantly fixedly installed on the pressure ring 8. The multiple magnetic blocks 10 are circumferentially arranged on the pressure ring 8 and magnetically connected to the metal ring 9. The metal ring 9 is made of magnetically conductive stainless steel and forms a stable magnetic attraction with the magnetic blocks 10. The magnetic blocks 10 are high-attraction permanent magnets, which are evenly distributed circumferentially, so that the pressure ring 8 is subjected to uniform force and the clamping force is stable. The magnetic attraction connection enables the pretreatment cylinder 7 to be quickly installed and disassembled without bolts or tools, which facilitates the cleaning and replacement of the filter screen 6 and equipment maintenance, and greatly improves the work efficiency.

[0028] Reference Figure 4 The mounting ring 5 has multiple positioning holes 11 equidistantly spaced around its circumference. Multiple positioning posts 12 are fixedly installed equidistantly around the upper circumference of the material cup 4. The multiple positioning posts 12 are respectively inserted into the multiple positioning holes 11. The positioning posts 12 and the positioning holes 11 form a circumferential limiting structure to prevent the mounting ring 5 and the filter screen 6 from rotating and shifting under the action of feeding impact, scraper rotation and airflow backflow, so as to ensure that the filter screen 6 is always in the center position, so as to achieve uniform filtration, smooth material feeding and avoid local blockage.

[0029] Reference Figure 7A bracket 13 is fixedly installed on the upper end of the pretreatment cylinder 7. A support rod 14 is horizontally fixedly installed on the bracket 13. A rotating shaft 15 is vertically rotatably installed on one end of the support rod 14. The lower end of the rotating shaft 15 extends into the pretreatment cylinder 7 and is fixedly installed with an arc-shaped scraper 16. The arc-shaped scraper 16 is slidably set on the upper surface of the filter screen 6. The bracket 13 and the support rod 14 form a rigid support structure to ensure that the rotating shaft 15 is vertically stable and rotates without shaking. The rotating shaft 15 provides rotational power output to the arc-shaped scraper 16. The arc of the arc-shaped scraper 16 is completely in contact with the surface of the conical filter screen 6. When rotating, it can continuously scrape and spread the solid impurities accumulated on the surface of the filter screen 6, prevent impurities from agglomerating and blocking the filter holes, ensure continuous and stable feeding of red oil, and avoid interruption of feeding and fluctuation of homogenization pressure due to poor filtration.

[0030] A drive motor 17 is fixedly installed on the bracket 13. The output shaft of the drive motor 17 is fixedly connected to the upper end of the rotating shaft 15. Multiple stirring rods 18 are horizontally fixedly installed on the rotating shaft 15. All stirring rods 18 are inside the pretreatment cylinder 7. The drive motor 17 provides stable power for rotation and the speed is adjustable. The stirring rods 18 rotate synchronously with the rotating shaft 15 to pre-stir and mix the spicy red oil in the pretreatment cylinder 7, break up the stratification of oil and residue, disperse the lumpy materials, and make the materials enter the filter screen 6 evenly for filtration, thereby improving the filtration efficiency and homogeneity stability. Stirring and scraping are carried out simultaneously to achieve integrated feeding and pretreatment.

[0031] Reference Figure 5 Multiple mounting bases 19 are fixedly installed equidistantly on the side wall of the material cup 4. Each mounting base 19 is fixedly mounted with a small air pump 20. The output end of each small air pump 20 is connected to a gas nozzle 21. Multiple through holes are opened on the side wall of the material cup 4. One end of the gas nozzle 21 passes through the through hole. The gas nozzle 21 and the through hole are sealed. The mounting base 19 provides a stable mounting carrier for the small air pump 20, ensuring that the air pump operates without vibration. The small air pump 20 generates clean compressed air with stable output pressure. The gas nozzle 21 is a food-grade thin tube, tilted towards the bottom of the inner conical surface of the filter screen 6, forming an upward airflow back jet, which powerfully blows off the fine residues adhering to the micropores of the filter screen 6, preventing fine impurities from clogging the holes. The sealing treatment prevents the material liquid from leaking.

[0032] Reference Figures 8-9A resistance ring 22 is fixedly installed on the side of the high-pressure homogenizing mechanism 2. The axis of the pressure regulating screw 3 coincides with the axis of the resistance ring 22. An adjusting block 23 is fixedly installed on one end of the pressure regulating screw 3. The adjusting block 23 is equipped with a limiting component for limiting the rotation of the pressure regulating screw 3. The resistance ring 22 is a high-friction coefficient annular contact surface, which provides a friction basis for limiting and locking. The pressure regulating screw 3 is connected to the homogenizing valve gap adjusting mechanism. Rotation can change the homogenizing pressure. The adjusting block 23 increases the force application area, which facilitates manual rotation to adjust the pressure. The limiting component automatically locks after the pressure is adjusted to prevent the pressure regulating screw 3 from rotating and the pressure from drifting due to equipment vibration. This ensures that the homogenizing pressure is constant throughout the process and the red oil homogenization effect is stable and consistent.

[0033] The adjusting block 23 has symmetrically arranged moving holes. The limiting component includes a moving rod 24 that is horizontally slidably installed in the moving hole, a rubber friction block 25 that is fixedly installed at one end of the moving rod 24, and a telescopic spring 26 that is sleeved on the moving rod 24. The two ends of the telescopic spring 26 are fixedly connected to the rubber friction block 25 and the adjusting block 23, respectively. The rubber friction block 25 is tightly fitted with the resistance ring 22. The moving hole provides a horizontal sliding guide for the moving rod 24 to ensure smooth sliding without jamming. The rubber friction block 25 is made of high wear-resistant and high-friction rubber, which generates strong friction when it is tightly fitted with the resistance ring 22 to achieve locking. The telescopic spring 26 is always in a compressed state, continuously pushing the moving rod 24 and the rubber friction block 25 to press against the resistance ring 22, achieving automatic locking without manual locking, and ensuring stable pressure without drift.

[0034] Two movable rods 24 are fixedly mounted with strip-shaped connecting rods 27 at one end. An adjusting block 23 has a vertically opening on the side away from the pressure adjusting screw 3. Sliding blocks 28 are symmetrically slidably mounted in the sliding groove. Support rods 29 are hinged to both sliding blocks 28. The ends of the two support rods 29 away from the adjusting block 23 are hinged to the strip-shaped connecting rods 27. Pressure plates 30 are fixedly mounted on both support rods 29. Anti-slip textures are provided on both pressure plates 30. The strip-shaped connecting rods 27 enable synchronous linkage between the two movable rods 24, ensuring simultaneous extension and retraction of the rubber friction blocks 25 on both sides. The sliding blocks 28 slide within the sliding groove, providing motion guidance for the support rods 29. The support rods 29 adopt a hinged structure. The pinching pressure is converted into horizontal tension, which pulls the moving rod 24 back to unlock. The overall linkage structure is simple and reliable, and the operation is labor-saving. The pressure plate 30 is easy for the operator to hold and pinch with one hand. The anti-slip texture increases friction and prevents slippage. When the pressure plate 30 is pinched, the two support rods 29 drive the sliding block 28 to move closer. The strip connecting rod 27 pulls the moving rod 24 and the rubber friction block 25 to disengage from the resistance ring 22. The adjusting block 23 can then be rotated freely to adjust the pressure. When the pressure plate 30 is released, the telescopic spring 26 automatically pushes the rubber friction block 25 to re-tighten the resistance ring 22, completing the locking. This achieves one-pinch unlocking and one-release locking, which is quick and precise in operation.

[0035] In this invention, the mounting ring 5 is placed on the upper end of the material cup 4, and the positioning hole 11 on the mounting ring 5 is aligned with the positioning post 12 on the material cup 4 for insertion to achieve circumferential positioning. The pressure ring 8 at the lower end of the pretreatment cylinder 7 is aligned with the upper end of the material cup 4 and lowered. The magnetic block 10 on the pressure ring 8 and the metal ring 9 are automatically magnetically attracted and engaged, and the mounting ring 5 is stably clamped between the pressure ring 8 and the material cup 4 to complete the quick installation of the filter screen 6. The magnetic attraction is checked to ensure that the filter screen 6 is not skewed and the sealing is reliable.

[0036] Hold and pinch the two pressure plates 30 with one hand. The pressure plates 30 drive the support rod 29 to move inward. The sliding block 28 slides along the moving groove. The strip connecting rod 27 pulls the two moving rods 24 to retract horizontally in sync. The rubber friction block 25 overcomes the elasticity of the telescopic spring 26 and disengages from the resistance ring 22, realizing the limit unlocking. Maintain the pinched state. Rotate the adjusting block 23 to drive the pressure adjusting screw 3 to rotate, accurately adjusting the homogenizing valve gap of the high-pressure homogenizing mechanism 2 to the target pressure. After the adjustment is completed, release the pressure plate 30. The telescopic spring 26 quickly returns to its original position, pushing the moving rod 24 and the rubber friction block 25 to tighten the resistance ring 22 again, completing the automatic pressure locking and ensuring that the pressure does not drift during operation.

[0037] The specially prepared spicy red oil material is slowly poured into the pretreatment cylinder 7 according to the formula. The drive motor 17 is started, and the drive motor 17 drives the rotating shaft 15 to rotate. The stirring rod 18 rotates with the shaft to premix and stir the red oil, breaking up the layers and dispersing the clumps. At the same time, the rotating shaft 15 drives the arc-shaped scraper 16 to rotate continuously along the surface of the conical filter screen 6 to scrape away the accumulated impurities and prevent the filter holes from being blocked. The small air pump 20 is started intermittently. The small air pump 20 generates compressed air and sprays it obliquely to the bottom of the filter screen 6 through the gas nozzle 21, forming an airflow backflow that blows off the adhering fine residue. Under the triple action of stirring, scraping and backflow, the material quickly and evenly passes through the filter screen 6 and enters the material cup 4. Solid impurities are completely intercepted on the upper surface of the filter screen 6.

[0038] After filtration, the red oil material enters the high-pressure homogenizing mechanism 2 through the connecting pipe 31. The high-pressure plunger pump inside the high-pressure homogenizing mechanism 2 draws the material into the pressurization chamber, forming high pressure and pushing it to the homogenizing valve assembly. Under ultra-high pressure, the material passes through the homogenizing valve slit at high speed. Under the quadruple action of shearing, impact, cavitation and turbulence, it is fully microemulsified, refined and homogenized to form a delicate, uniform and stable spicy red oil. After homogenization, the red oil is continuously discharged from the outlet and can be directly collected, bottled or entered into the next process.

[0039] The entire processing flow solves problems such as solid impurities clogging the homogenization channel, homogenization pressure fluctuations, strong granular texture of red oil layering, and cumbersome equipment maintenance through pretreatment filtration, double anti-clogging, pressure self-locking, and quick disassembly structure. This results in spicy red oil that is homogeneous and delicate, with uniform flavor and stable color, fully meeting the high-quality seasoning requirements of snack foods.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
