Oil tank and Sichuan pepper oil production line

Abstract

This application discloses an oil tank and a Sichuan pepper oil production line. By setting independent oil chambers and stirring chambers inside the tank, the stirring element allows for full contact between the oil and Sichuan pepper powder, improving extraction efficiency and the dissolution rate of flavor substances. Simultaneously, the agitation generated by the stirring helps the oil pass evenly through a first filter element located on the partition wall between the stirring chamber and the oil chamber, achieving continuous and stable solid-liquid separation. During this process, Sichuan pepper residue is retained in the stirring chamber. The pipe joint connected to the stirring chamber can be used to connect to other systems for further processing of the Sichuan pepper residue, while the pipe joint connected to the oil chamber can be used to discharge the filtered Sichuan pepper oil, preventing secondary contamination. This oil tank allows for the completion of feeding, stirring, filtering, and oil discharge within the same container, eliminating the need for intermediate material transfer, shortening the production cycle, improving operational efficiency, and preventing spillage, splashing, or residue, thus avoiding raw material waste and ensuring food safety and workshop hygiene.

Description

Technical Field

[0001] This application relates to the field of food production technology, and in particular to an oil tank and a pepper oil production line. Background Technology

[0002] Sichuan peppercorn oil is a traditional condiment widely used in Chinese cuisine, and it is loved by consumers for its unique numbing and fragrant flavor. Its preparation typically involves mixing Sichuan peppercorn powder with edible oil and then soaking it at room temperature or extracting it by heating. This process allows the flavor compounds in the Sichuan peppercorns to dissolve into the oil phase, resulting in a functional condiment oil with a rich aroma.

[0003] In existing production processes, open containers (such as stainless steel drums, glass tanks, etc.) are commonly used as mixing devices. First, pepper powder and edible oil are added to the container and stirred or left to soak. After extraction, the mixture is transferred to a filtration device (such as a filter screen, centrifuge, or filter press) for solid-liquid separation to obtain a clear pepper oil product.

[0004] However, since mixing and filtration are two independent processes completed in different devices, the high-viscosity, high-sludge-content oil-powder mixture must be manually or pumped for transfer, resulting in a cumbersome process, long operation cycle, and low production efficiency. Furthermore, material spillage, splashing, or residue is highly likely during the transfer process, not only wasting raw materials but also potentially causing cross-contamination, affecting food safety and workshop hygiene. Utility Model Content

[0005] The purpose of this application is to provide an oil tank and a pepper oil production line that can complete the feeding, stirring, filtering and oil discharge process in the same container without the need to transfer materials in the middle, shorten the production cycle, improve the operation efficiency, and at the same time eliminate spillage, splashing or residue, avoid raw material waste, and ensure food safety and workshop hygiene.

[0006] The embodiments of this application can be implemented as follows: In the first aspect, this utility model provides an oil tank for producing Sichuan pepper oil, comprising a tank body and a stirring component; The tank body has an oil chamber and a stirring chamber, and pipe joints are respectively provided on the outer wall of the tank body in the areas corresponding to the oil chamber and the stirring chamber; The stirring element is disposed inside the stirring chamber and is used to stir the oil-powder mixture inside the stirring chamber; The partition wall between the oil chamber and the stirring chamber is provided with a first filter element.

[0007] In an optional embodiment, the oil chamber and the stirring chamber are arranged along the length of the tank body; The two side walls in the width direction of the pool body are the first side wall and the second side wall, respectively, and the pipe joint is located on the first side wall; In particular, from the second sidewall to the first sidewall, the height of the bottom wall of the pool gradually decreases.

[0008] In an optional embodiment, the oil tank further includes a first partition, which is located above the partition and is detachably connected to the two side walls of the tank body, wherein the first partition is equipped with a second filter element.

[0009] In an optional embodiment, a first limiting strip is provided on the side wall of the pool body. The first limiting strip extends along the height direction of the pool body, and a first guide groove is formed between two first limiting strips. The edge of the first partition can be slidably embedded in the first guide groove.

[0010] In an optional embodiment, the upper edge of the first partition is provided with a first handle.

[0011] In an optional embodiment, the oil tank further includes a second baffle located within the oil cavity to divide the oil cavity into a front cavity and a rear cavity, the front cavity being closer to the stirring chamber than the rear cavity; the front cavity and the rear cavity are each connected to a pipe joint; The second partition is detachably connected to the two side walls of the pool body, and the second partition is equipped with a third filter element.

[0012] In an optional embodiment, a second limiting strip is provided on the side wall of the pool body. The second limiting strip extends along the height direction of the pool body, and a second guide groove is formed between the two second limiting strips. The edge of the second partition can be slidably embedded in the second guide groove.

[0013] In an optional embodiment, the upper edge of the second partition is provided with a second handle.

[0014] In an optional embodiment, both the pipe joint communicating with the front cavity and the pipe joint communicating with the stirring chamber are tee joints, one of which is used to connect to the suction pump.

[0015] Secondly, this utility model provides a Sichuan pepper oil production line, including the oil tank described in any of the aforementioned embodiments.

[0016] Compared with the prior art, the beneficial effects of the embodiments of this application include, for example: By setting up independent oil chambers and stirring chambers inside the tank, the oil and pepper powder are poured into the stirring chamber. The stirring element allows the oil and pepper powder to come into full contact, improving extraction efficiency and the dissolution rate of flavor substances. Simultaneously, the agitation generated by the stirring helps the oil pass evenly through the first filter element located on the partition wall between the stirring chamber and the oil chamber, achieving continuous and stable solid-liquid separation. During this process, pepper residue is effectively retained in the stirring chamber, preventing it from entering the oil chamber and causing contamination, thus ensuring that the pepper oil collected in the oil chamber has high clarity and purity. The pipe joint connected to the stirring chamber can be used to connect to a slag discharge system or a filtration system to achieve automatic removal and further filtration of pepper residue. The pipe joint connected to the oil chamber can be used to export the filtered, clarified pepper oil, avoiding secondary contamination.

[0017] Therefore, this oil tank can complete the process of feeding, stirring, filtering and oil discharge in the same container without the need to transfer materials in the middle, shorten the production cycle, improve the operation efficiency, and at the same time eliminate spills, splashes or residues, avoid raw material waste, and ensure food safety and workshop hygiene.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] refer to Figures 1 to 4 This application discloses an oil tank, which includes a tank body 10 and a stirring component 20; The tank body 10 has an oil chamber 13 and a stirring chamber 12, and pipe joints 70 are respectively provided on the outer wall of the tank body 10 in the areas corresponding to the oil chamber 13 and the stirring chamber 12. The stirring element 20 is disposed in the stirring chamber 12 and is used to stir the oil-powder mixture in the stirring chamber 12; The first filter element 14 is provided on the partition wall 11 between the oil chamber 13 and the stirring chamber 12.

[0029] In this way, by setting independent oil chambers 13 and stirring chambers 12 inside the tank 10, when oil and pepper powder are poured into the stirring chamber 12, the stirring element 20 allows the oil and pepper powder to come into full contact, improving extraction efficiency and the dissolution rate of flavor substances. Simultaneously, the agitation generated by stirring helps the oil pass evenly through the first filter element 14 set on the partition wall 11 between the stirring chamber 12 and the oil chamber 13 into the oil chamber 13, achieving continuous and stable solid-liquid separation. During this process, pepper residue is effectively retained in the stirring chamber 12, preventing it from entering the oil chamber 13 and causing contamination, thus ensuring that the pepper oil collected in the oil chamber 13 has high clarity and purity. The pipe joint 70 connected to the stirring chamber 12 can be used to connect to a slag discharge system or a filtration system to achieve automatic removal and further filtration of pepper residue. The pipe joint 70 connected to the oil chamber 13 can be used to export the filtered, clarified pepper oil, avoiding secondary contamination.

[0030] Therefore, this oil tank can complete the process of feeding, stirring, filtering and oil discharge in the same container without the need to transfer materials in the middle, shorten the production cycle, improve the operation efficiency, and at the same time eliminate spills, splashes or residues, avoid raw material waste, and ensure food safety and workshop hygiene.

[0031] Furthermore, the continuous action of the agitator 20 prevents powder from accumulating on the filter surface to form a dense filter cake layer, effectively alleviating filter clogging problems, maintaining stable filtration flux, extending continuous operating time, and reducing cleaning frequency and maintenance costs. The pipe connector 70 of the agitator chamber 12 can be connected to a cleaning fluid supply system to achieve in-situ flushing of the reaction zone, thoroughly removing residues, complying with food safety regulations, and reducing the risk of cross-contamination.

[0032] Optionally, the oil chamber 13 and the stirring chamber 12 are arranged along the length of the tank body 10; that is, the two chambers are arranged side by side on the longitudinal axis of the tank body 10, sharing the middle partition wall 11, on which the first filter element 14 is provided.

[0033] The two side walls of the pool body 10 in the width direction are the first side wall 15 and the second side wall 16, respectively. The pipe joints 70 (including the pipe joints 70 for connecting the stirring chamber 12 and the pipe joints 70 for connecting the oil chamber 13) are located on the first side wall 15; this facilitates centralized connection of external pipelines, reduces the scattered distribution of interfaces, and improves the neatness and maintainability of the equipment.

[0034] In this configuration, from the second sidewall 16 to the first sidewall 15, the bottom wall 17 of the tank body 10 is inclined downwards, meaning the height of the bottom wall 17 of the tank body 10 gradually decreases, forming a sloping structure towards the first sidewall 15. This inclined bottom wall 17 penetrates the stirring chamber 12 and the oil chamber 13 area, allowing liquid and residue to naturally converge towards the first sidewall 15 under the action of gravity.

[0035] In this way, the bottom wall 17 of the tank body 10 gradually slopes down from the second side wall 16 to the first side wall 15, forming a guide slope. After filtration, the oil flows naturally to the oil outlet located on the first side wall 15 under the action of gravity; at the same time, the pepper residue remaining after stirring also slides to the first side wall 15 due to the slope structure, avoiding the liquid retention area or residue accumulation dead corners commonly found in flat-bottom structures, ensuring that the mixture in the stirring chamber 12 fully contacts the filter element, and the finished oil in the oil chamber 13 can be completely discharged, reducing material residue and improving the oil yield and raw material utilization rate.

[0036] The oil tank also includes a first partition 30, which is located above the partition wall 11 and extends along the width of the tank body 10. The first partition 30 is detachably connected to the two side walls (first side wall 15 and second side wall 16) of the tank body 10.

[0037] The first partition 30 is equipped with a second filter element, which can be a filter screen, filter cloth or sintered porous plate or other element with filtration function, used to pre-filter or secondary filter the oil-powder mixture in the mixing chamber 12.

[0038] In this way, the second filter element is located at the top of the mixing chamber 12. During the mixing process, the clearer oil from the upper layer can naturally flow through the second filter element into the oil chamber 13. This, combined with the first filter element 14 located on the partition wall 11, provides double filtration, improving the purity and sensory quality of the Sichuan pepper oil. Since the first partition 30 is detachably connected to the side wall of the tank body 10, it can be removed to clean the second filter element, preventing long-term clogging and ensuring stable long-term operation of the equipment.

[0039] A first limiting strip 40 is provided on the side wall of the pool body 10, extending along the height direction of the pool body 10. A first guide groove 41 is formed between two first limiting strips 40. The edge of the first partition 30 can be slidably embedded in the first guide groove 41, that is, the first partition 30 achieves vertical lifting and lowering movement through the cooperation of its side with the first guide groove 41. This structure guides the first partition 30 to move smoothly along a predetermined trajectory, preventing it from tilting, getting stuck, or coming off backward or forward during the sliding and stirring processes. This allows the first partition 30 to be completely pulled out from the top of the first guide groove 41, achieving quick disassembly without tools, which facilitates rinsing or replacement of the second filter element.

[0040] The first limiting strip 40 is generally L-shaped and can be made of stainless steel strip by bending. It has good mechanical strength and corrosion resistance. The first limiting strip 40 includes a first strip part and a second strip part connected at an angle. The first strip part is welded to the side wall of the pool body 10. A first guide groove 41 is formed between the second strip parts of the two first limiting strips 40.

[0041] Thus, the L-shaped structure of the first limiting strip 40 has good bending and torsional stiffness, and can maintain its shape stability, especially when it extends vertically for a long time, avoiding sagging or twisting due to its own weight or external forces. This ensures that the first guide groove 41 has consistent dimensions throughout its entire height range, guaranteeing smooth sliding of the first partition 30. The first strip is directly fixed to the side wall of the pool body 10 by welding, forming a metallurgical bond. The connection strength is much higher than that of mechanical connections such as screws or clips, and it can withstand dynamic loads such as stirring vibration and frequent sliding, without loosening even after long-term use.

[0042] The upper edge of the first partition 30 is provided with a first handle 31. The first handle 31 can be a U-shaped, ring-shaped, or strip-shaped protrusion made of metal or food-grade plastic, and is connected to the first partition 30 by welding, screw connection, or integral molding. When it is necessary to lift or pull the first partition 30 out of the pool body 10, the operator can hold the first handle 31 to apply an upward or outward pulling force, so that the first partition 30 can slide smoothly along the first guide groove 41, making the lifting or pulling operation of the first partition 30 more effortless and smoother.

[0043] The surface of the first handle 31 may be provided with anti-slip texture or covered with elastic material to enhance grip comfort and friction, prevent slippage, and improve operational safety.

[0044] The oil tank also includes a second partition 50, which is located within the oil cavity 13 to divide the oil cavity 13 into a front cavity 130 and a rear cavity 131. The front cavity 130 is closer to the stirring chamber 12 than the rear cavity 131. The front cavity 130 and the rear cavity 131 are each connected to a pipe joint 70. The second partition 50 is detachably connected to the two side walls (i.e., the first side wall 15 and the second side wall 16) of the tank body 10, and a third filter element is installed on the second partition 50.

[0045] Thus, the front chamber 130 receives the oil after preliminary filtration by the first filter element 14, while the rear chamber 131 stores the finished oil after further purification by the third filter element. The pipe connector 70 connected to the front chamber 130 allows for applications where high clarity of the pepper oil is not required, while the pipe connector 70 connected to the rear chamber 131 yields high-quality finished oil. The second partition 50 acts as a physical barrier, isolating the primary filtration zone from the secondary filtration zone, preventing fine impurities that may have accumulated in the front chamber 130 from re-entering the rear chamber 131, and ensuring that the finished oil is not contaminated by backflow. The second partition 50 is removable, exposing the third filter element to the outside, facilitating manual or automatic cleaning and replacement of the filter media, preventing long-term clogging that could lead to increased pressure drop or filtration failure, and ensuring long-term stable operation of the system.

[0046] A second limiting strip 60 is provided on the side wall of the pool body 10, extending along the height direction of the pool body 10. A second guide groove 61 is formed between the two second limiting strips 60, and the edge of the second partition 50 can be slidably embedded in the second guide groove 61. That is, the second partition 50 achieves vertical lifting and lowering movement through the cooperation of its side with the second guide groove 61. This structure guides the second partition 50 to move smoothly along a predetermined trajectory, preventing it from tilting, getting stuck, or coming off backward or forward during the sliding and stirring processes. This allows the second partition 50 to be completely pulled out from the top of the second guide groove 61, enabling quick disassembly without tools and facilitating the rinsing or replacement of the third filter element.

[0047] The second limiting strip 60 is generally L-shaped and can be made of stainless steel strip by bending. It has good mechanical strength and corrosion resistance. The second limiting strip 60 includes a third strip and a fourth strip connected at an angle. The third strip is welded to the side wall of the pool body 10. A second guide groove 61 is formed between the fourth strips of the two second limiting strips 60.

[0048] Thus, the L-shaped structure of the second limiting strip 60 has good bending and torsional stiffness, and can maintain its shape stability, especially when it extends vertically for a long time, avoiding sagging or twisting due to its own weight or external forces. This ensures that the second guide groove 61 has consistent dimensions throughout its height range and guarantees smooth sliding of the second partition 50. The third part is directly fixed to the side wall of the pool body 10 by welding, forming a metallurgical bond. The connection strength is much higher than that of mechanical connection methods such as screws or clips, and it can withstand dynamic loads such as stirring vibration and frequent sliding, and will not loosen after long-term use.

[0049] The upper edge of the second partition 50 is provided with a second handle 51. The second handle 51 can be a U-shaped, ring-shaped, or strip-shaped protrusion made of metal or food-grade plastic, and is connected to the second partition 50 by welding, screw connection, or integral molding. When it is necessary to lift or pull the second partition 50 out of the pool body 10, the operator can hold the second handle 51 to apply an upward or outward pulling force, so that the second partition 50 can slide smoothly along the second guide groove 61, making the lifting or pulling operation of the second partition 50 more effortless and smooth.

[0050] The surface of the second handle 51 may be provided with anti-slip texture or covered with elastic material to enhance grip comfort and friction, prevent slippage, and improve operational safety.

[0051] The pipe joint 70 communicating with the front chamber 130 and the pipe joint 70 communicating with the stirring chamber 12 are both tee joints, and one of the interfaces of these two pipe joints 70 is used to connect to the suction pump.

[0052] In other words, for the tee fitting 70, one port connects to the mixing chamber 12 (or the front chamber 130), one port is used to connect to a suction pump (such as a vacuum pump, rotor pump, or diaphragm pump), the suction pump provides active dredging power to pump the oil-powder mixture to another device for further filtration to obtain pure oil, and the other port is used to connect to the oil-using equipment.

[0053] The mixing component 20 can specifically be an agitator (also known as a spiral mixing shaft or ribbon agitator), which includes a rotating shaft and a blade structure that extends spirally along the axial direction, and can be driven to rotate by a motor.

[0054] The auger is installed inside the mixing chamber 12, and its axis can be arranged along the length or width of the tank body 10, preferably along the length, so as to cover most of the area of ​​the mixing chamber 12. The spiral blades of the auger maintain an appropriate gap with the bottom wall 17 of the mixing chamber 12, which avoids friction and wear, and can effectively drive the oil-powder mixture to move axially or circumferentially.

[0055] During operation, the auger continuously rotates to forcefully stir the pepper powder and cooking oil, promoting full contact and mass transfer between the two phases and accelerating the dissolution of flavor substances.

[0056] Optionally, the auger can be a single-head or multi-head spiral structure. Its pitch, direction of rotation (left-hand / right-hand), and blade width can be optimized according to the size of the mixing chamber 12 and process requirements to achieve the best mixing effect.

[0057] In addition, this application also discloses a Sichuan pepper oil production line, which includes the oil tank described in the above embodiment.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
