Description

Technical Field

[0001] This application relates to the field of Sichuan pepper oil processing technology, specifically to a hot oil cooling device in the process of Sichuan pepper oil processing. Background Technology

[0002] Sichuan pepper oil is a liquid condiment made primarily from Sichuan peppercorns. Modern extraction processes, such as spray extraction, are used to extract the numbing and aromatic compounds from the peppercorns into edible oil. When processing Sichuan pepper oil using the spray extraction method with hot oil extraction, rapeseed oil or soybean oil heated to a suitable temperature is typically poured over the Sichuan peppercorns to extract the effective aromatic and numbing components. After extraction, the still-warm oil is usually cooled rapidly to prevent excessive volatilization of the extracted heat-sensitive active substances under sustained high temperatures. This also prevents some of the extracted active substances from developing bitter or burnt flavors at high temperatures, which would degrade the flavor of the finished oil.

[0003] Currently, common shell-and-tube or plate heat exchangers are generally used to cool hot oil. However, after extraction, hot oil is easily mixed with solid impurities from Sichuan pepper. These solid impurities tend to deposit in the fluid channels of the heat exchanger, causing blockages. Therefore, the fluid channels of the heat exchanger need to be cleaned frequently, which requires shutting down the production line and reducing the production efficiency of Sichuan pepper oil. At the same time, the heat of the hot oil is directly exchanged with the cooling water, which easily leads to the direct waste of heat and affects the energy consumption of the entire production line. Summary of the Invention

[0004] To address the aforementioned deficiencies in the prior art, this application provides a hot oil cooling device for the processing of Sichuan pepper oil, which can improve production efficiency, reduce heat waste, and has strong practicality.

[0005] To achieve the above objectives, the present invention employs the following techniques:

[0006] A hot oil cooling device for processing Sichuan pepper oil includes:

[0007] A water tank, with an inlet pipe connected to its upper end and an outlet pipe connected to its lower end;

[0008] Multiple oil transfer mains are arranged in an array along the height of the water tank. Each main is inserted along the length of the water tank and both ends extend out of the water tank. One end of each oil transfer main is open and threaded with a first cap. The other end is equipped with an exhaust valve. Inside each oil transfer main, a pair of sliding discs are coaxially slidably fitted. Each pair of sliding discs is coaxially connected with a connecting rod.

[0009] There are multiple oil transfer auxiliary pipes, which are respectively located between adjacent oil transfer main pipes and on the oil transfer main pipes at both ends of the array. The two ends of the oil transfer auxiliary pipes located between adjacent oil transfer main pipes are respectively connected to the corresponding oil transfer main pipes. One end of the oil transfer auxiliary pipes located on the oil transfer main pipes at both ends of the array is respectively connected to the oil transfer main pipe. The two oil transfer auxiliary pipes connected to one oil transfer main pipe are respectively located at both ends of the side wall of the oil transfer main pipe, and the distance between them is less than the length of the connecting rod. All oil transfer auxiliary pipes are set along the height direction of the water tank.

[0010] There are multiple backup pipes, each corresponding to a main oil pipeline. All backup pipes are installed inside the water tank with both ends extending out of the tank. Each backup pipe is connected to two auxiliary oil pipelines located on the corresponding main oil pipeline. Each auxiliary oil pipeline is equipped with a first valve located between the end of the backup pipe and the corresponding main oil pipeline. Each backup pipe is also equipped with two second valves located at both ends of the backup pipe.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. By setting up a spare pipe, the hot oil in the other oil pipelines can still be cooled while the space inside one main oil pipeline is being cleaned, thus improving the production efficiency of Sichuan pepper oil.

[0013] 2. By setting up the first and second sleeves, it is possible to preheat the cold oil while cooling the hot oil, which reduces heat waste and plays a positive role in the energy consumption of the entire production line. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a hot oil cooling device for the processing of Sichuan pepper oil, including a water tank 1, a main oil supply pipe 2, a secondary oil supply pipe 3, and a spare pipe 4.

[0030] Specifically, such as Figure 1 As shown, the upper end of the water tank 1 is connected to the water inlet pipe 11, and the lower end is connected to the water outlet pipe 12. The water inlet pipe 11 is used to fill the water tank 1 with cooling water, and the water outlet pipe 12 is used to discharge the cooling water in the water tank 1.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, there are multiple oil pipelines 2 extending along the length of the water tank 1 inside the water tank 1. In this example, fourteen oil pipelines 2 are provided in one water tank 1. Both ends of the oil pipelines 2 extend outside the water tank 1. The oil pipelines 2 are arranged in a linear array with the array direction parallel to the height direction of the water tank 1. One end of each oil pipeline 2 is open and threaded with a first cap 21, which is used to seal one end of the oil pipeline 2. The other end of each oil pipeline 2 is provided with an exhaust valve 22, which is used to control the gas flow at the other end of the oil pipeline 2. A pair of sliding discs 23 are coaxially slidably fitted inside each oil pipeline 2. The contact surface between the side of the sliding disc 23 and the inner wall of the oil pipeline 2 is liquid-tight. A connecting rod 24 is coaxially connected between each pair of sliding discs 23.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, there are multiple oil transfer auxiliary pipes 3. In this example, one water tank 1 is provided with fifteen oil transfer auxiliary pipes 3. The oil transfer auxiliary pipes 3 are respectively located between adjacent oil transfer main pipes 2 and on the oil transfer main pipes 2 at both ends of the array. The oil transfer main pipes 2 at both ends of the array are the uppermost and lowermost oil transfer main pipes 2. The two ends of the oil transfer auxiliary pipes 3 located between adjacent oil transfer main pipes 2 are respectively connected to the corresponding oil transfer main pipes 2. One end of the oil transfer auxiliary pipes 3 located on the oil transfer main pipes 2 at both ends of the array is respectively connected to the oil transfer main pipe 2. The two oil transfer auxiliary pipes 3 connected to one oil transfer main pipe 2 are respectively located at both ends of the side wall of the oil transfer main pipe 2, and their distance is less than the length of the connecting rod 24. This design is used to make the initial position of the slide plate 23 located between the two oil transfer auxiliary pipes 3 and the two ends of the oil transfer main pipe 2. The oil transfer auxiliary pipes 3 are all set along the height direction of the water tank.

[0033] Specifically, such as Figure 3 As shown, there are multiple spare pipes 4 corresponding to the main oil supply pipes 2. In this example, one water tank 1 is provided with fourteen spare pipes 4, and each spare pipe 4 corresponds to one main oil supply pipe 2. The spare pipes 4 are all installed inside the water tank 1 and both ends of the spare pipes 4 extend out of the water tank 1. The two ends of the spare pipes 4 are respectively connected to two auxiliary oil supply pipes 3 located on the corresponding main oil supply pipe 2. Each auxiliary oil supply pipe 3 is provided with a first valve 31. The first valve 31 is located between the end of the spare pipe 4 and the corresponding main oil supply pipe 2. The first valve 31 is used to control the liquid flow of the auxiliary oil supply pipe 3. Each spare pipe 4 is provided with two second valves 41. The second valves 41 are located at both ends of the spare pipe 4. The second valves 41 are used to control the liquid flow between the two ends of the spare pipe 4 and the auxiliary oil supply pipes 3.

[0034] During operation, cooling water is introduced into the water tank 1 through the inlet pipe 11, filling the water tank 1 completely. Using an external pumping mechanism, the hot oil to be cooled is sent into the auxiliary oil pipe 3, which is separately connected to the bottom oil main pipe 2. The hot oil passes through the auxiliary oil pipe 3, the main oil pipe 2, the next auxiliary oil pipe 3, the next main oil pipe 2, and so on, until it leaves from the auxiliary oil pipe 3, which is separately connected to the top oil main pipe 2. When the hot oil flows through the main oil pipe 2, the hot oil and the cooling water in the water tank 1 exchange heat through the pipe wall of the main oil pipe 2 to achieve the purpose of cooling the hot oil.

[0035] However, in the processing of Sichuan pepper oil, the hot oil that needs to be cooled is generally the hot oil that has already come into contact with the Sichuan pepper and extracted the effective numbing components. During the initial extraction process, the hot oil inevitably carries a significant amount of impurities, such as the outer shell and stem segments of the Sichuan pepper. These impurities tend to deposit inside the main oil supply pipe 2, potentially causing blockages or contamination of the hot oil. Therefore, the main oil supply pipe 2 needs to be cleaned regularly. However, cleaning the main oil supply pipe 2 usually requires shutting down the entire machine, as it's impossible to ensure the continued operation of the other main oil supply pipes 2 while cleaning a single one, significantly reducing the production efficiency of Sichuan pepper oil. Therefore, in this example, a spare pipe 4 structure is introduced: when the flow rate of hot oil from the auxiliary oil supply pipe 3 connected to the uppermost main oil supply pipe 2 decreases significantly, or when a particular main oil supply pipe 2 meets the time limit for cleaning, the corresponding spare pipe 4 is selected. To clean the main oil pipe 2, close the first valve 31 on the auxiliary oil pipe 3 and open the two second valves 41 on the corresponding spare pipe 4. Hot oil about to flow through the main oil pipe 2 will directly enter the next main oil pipe 2 from the spare pipe 4. At this time, open the first cap 21 and vent valve 22 of the main oil pipe 2, and move the sliding plate 23 outwards. The sliding plate 23 will cause the remaining hot oil in the main oil pipe 2 to leave from the open end of the main oil pipe 2. Simultaneously, the sliding plate 23 will scrape away any remaining impurities on the inner wall of the main oil pipe 2 and cause these impurities to leave from the open end of the main oil pipe 2. After cleaning, return the sliding plate 23 to its original position, close the vent valve 22 again, and replace the first cap 21. Close the two second valves 41 and reopen the first valve 31. Then, the cleaning of the next main oil pipe 2 can begin.

[0036] Preferred, such as Figure 2 As shown, each slide plate 23 near the first cover 21 is equipped with a pull ring 25, which is located on the side of the slide plate 23 facing the first cover 21.

[0037] This design allows the slide plate 23 and connecting rod 24 to be pulled out of the oil supply main pipe 2 using external hooks, avoiding the difficulty of directly pulling out the slide plate 23 and connecting rod 24 under high temperature conditions.

[0038] Preferred, such as Figure 2 As shown, both ends of the side wall of the main oil pipeline 2 are connected to short pipes 26. The short pipes 26 are coaxially arranged with the auxiliary oil pipeline 3. The end of the short pipe 26 facing away from the main oil pipeline 2 is open and threaded with a second cap 27.

[0039] With this design, the short pipe 26 serves two purposes: first, when cleaning the main oil supply pipe 2, the hot oil between the sliding plates 23 can be directly discharged from the short pipe 26, and the hot oil can be collected in a container in advance to avoid waste or spillage in the environment and pollution of the working environment; second, external cleaning tools such as cleaning brushes can be inserted through the short pipe 26 to clean part of the space inside the oil supply branch pipe 3.

[0040] Preferred, such as Figure 4 As shown, each of the spare pipes 4 is connected to an oil drain pipe 42. The end of the oil drain pipe 42 facing away from the spare pipe 4 is open and is fitted with a third cap 43.

[0041] With this design, since hot oil remains in the corresponding spare pipe 4 after the main oil pipe 2 is cleaned, a drain pipe 42 is introduced here to drain the hot oil in the spare pipe 4 in a timely manner and avoid waste of hot oil. More preferably, if the spare pipe 4 is inclined, the drain pipe 42 should be set at the lower end of the spare pipe 4 so that all the hot oil in the spare pipe 4 can flow out from the drain pipe 42.

[0042] Preferred, such as Figure 2 As shown, filter discs 28 are coaxially sleeved in the middle of the connecting rod 24, and the side of the filter discs 28 has liquid-tight contact with the inner wall of the oil pipeline 2.

[0043] With this design, impurities in the hot oil can be filtered multiple times through the filter disc 28, and the filter disc 28 can be cleaned in time as it moves out of the oil main pipe 2 along with the connecting rod 24.

[0044] Example 2

[0045] like Figure 5 and Figure 6 As shown, this embodiment provides a hot oil cooling device for the processing of Sichuan pepper oil, which, based on the scheme described in Embodiment 1, further includes a first sleeve 5, a first connecting pipe 51, a second sleeve 6, and a second connecting pipe 61.

[0046] Preferred, such as Figure 1 and Figure 5As shown, the number of first sleeves 5 matches the number of main oil pipes 2. In this example, a water tank 1 is provided with fourteen first sleeves 5. The first sleeves 5 are coaxially sleeved around the periphery of the main oil pipe 2. There is a gap between the inner wall of the first sleeve 5 and the outer wall of the main oil pipe 2. The first sleeve 5 is located between two auxiliary oil pipes 3 on the corresponding main oil pipe 2. The first sleeves 5 are all inserted into the water tank 1 and both ends of the first sleeve 5 extend out of the water tank 1. Both ends of the first sleeve 5 are closed to the outer wall of the main oil pipe 2. The adjacent first sleeves 5 and the uppermost and lowermost first sleeves 5 are connected by first connecting pipes 51. The two first connecting pipes 51 connected to a first sleeve 5 are located at both ends of the side wall of the first sleeve 5. The first connecting pipes 51 are all set along the height direction of the water tank 1.

[0047] During operation, cold oil is pumped into the first connecting pipe 51, which is separately connected to the first sleeve 5 at the bottom, through an external cold oil pumping mechanism. The cold oil passes through the first connecting pipe 51, the first sleeve 5, the next first connecting pipe 51, the next first sleeve 5, and so on, until it leaves from the first connecting pipe 51, which is separately connected to the first sleeve 5 at the top. With this design, while the hot oil dissipates heat, it can fully exchange heat with the cold oil through the pipe wall of the oil conveying main pipe 2, preheating the cold oil and saving the time and energy consumption of heating before subsequent cold oil extraction.

[0048] Preferred, such as Figure 1 and Figure 6 As shown, a second sleeve 6 is coaxially sleeved on the periphery of the first sleeve 5. There is a gap between the inner wall of the second sleeve 6 and the outer wall of the first sleeve 5. The second sleeve 6 is located between two first connecting pipes 51 corresponding to the first sleeve 5. The second sleeve 6 is inserted into the water tank 1 and both ends of it extend out of the water tank 1. Both ends of the second sleeve 6 are closed to the outer wall of the first sleeve 5. The adjacent second sleeves 6 and the uppermost and lowermost second sleeves 6 are connected by second connecting pipes 61. The two second connecting pipes 61 connected to one second sleeve 6 are located at both ends of the side wall of the second sleeve 6. The second connecting pipes 61 are all set along the height direction of the water tank 1.

[0049] During operation, hot oil exiting from the auxiliary oil pipe 3, which is separately connected to the uppermost main oil pipe 2, is poured into the second connecting pipe 61, which is separately connected to the uppermost second sleeve pipe 6. The hot oil passes sequentially through the second connecting pipe 61, the second sleeve pipe 6, the next second connecting pipe 61, and so on, until it exits from the second connecting pipe 61, which is separately connected to the lowermost second sleeve pipe 6. With this design, the hot oil can undergo three layers of heat exchange: heat exchange between the main oil pipe 2 and the cold oil in the first sleeve pipe 5, heat exchange again between the first sleeve pipe 5 and the cold oil in the first sleeve pipe 5, and heat exchange between the second sleeve pipe 6 and the cooling water in the water tank 1, thereby achieving the purpose of sufficient cooling. The cold oil can undergo two layers of heat exchange: heat exchange between the main oil pipe 2 and the hot oil in the main oil pipe 2, and heat exchange between the first sleeve pipe 5 and the hot oil in the second sleeve pipe 6, thereby achieving the purpose of sufficient preheating.

[0050] Example 3

[0051] like Figures 7-12 As shown, this embodiment provides a hot oil cooling device for the processing of Sichuan pepper oil. Based on the scheme described in Embodiment 2, it also includes multiple water tanks 1. In this example, four water tanks 1 are provided.

[0052] Each water tank 1 has a separate oil supply branch pipe 3 connected to the bottom oil supply main pipe 2, which is connected to the same oil inlet pipe 29. One end of the oil inlet pipe 29 is open and used to connect with external hot oil pumping equipment. Each water tank 1 has a separate oil supply branch pipe 3 connected to the top oil supply main pipe 2, which is connected to the same oil passage pipe 210. Both ends of the oil passage pipe 210 are closed.

[0053] Each water tank 1 has a second connecting pipe 61 connected to the oil pipe 210 on the second sleeve 6 at the top. Each water tank 1 has a third valve 62 on the second connecting pipe 61 connected to the second sleeve 6 at the top. Each water tank 1 has a second connecting pipe 61 connected to the second sleeve 6 at the bottom. Each water tank 1 has the same oil outlet pipe 63. One end of the oil outlet pipe 63 is open and used to connect with the external oil storage mechanism. Each water tank 1 has a fourth valve 64 on the second connecting pipe 61 connected to the second sleeve 6 at the bottom.

[0054] Each water tank 1 has a first connecting pipe 51 at the bottom of the first sleeve 5 connected to the same inlet pipe 52. One end of the inlet pipe 52 is open and used to connect with external cold oil pumping equipment. Each water tank 1 has a fifth valve 53 on its first connecting pipe 51 at the bottom of the first sleeve 5. Each water tank 1 has a first connecting pipe 51 at the top of the first sleeve 5 connected to the same outlet pipe 54. One end of the outlet pipe 54 is open and used to connect with external oil heating equipment. Each water tank 1 has a sixth valve 55 on its first connecting pipe 51 at the top of the first sleeve 5.

[0055] This design allows for the dynamic selection of the number of water tanks 1 to be activated based on the current required amount of hot oil to be cooled. For example, if the current required amount of hot oil to be cooled necessitates the activation of two water tanks 1, then two water tanks 1 are selected, and the first valve 31, third valve 62, fourth valve 64, fifth valve 53, and sixth valve 55 matched to these two water tanks 1 are opened, while the first valve 31, third valve 62, fourth valve 64, fifth valve 53, and sixth valve 55 matched to the other water tanks 1 are kept closed. The hot oil can then be cooled according to the workflow described above.

[0056] Preferred, such as Figure 1 As shown, multiple partitions 13 are arranged in parallel along their length in the water tank 1. In this example, four partitions 13 are provided. The sides of each partition 13 are connected to the inner wall of the water tank 1. Each partition 13 has a water inlet 14. The water inlets 14 of adjacent partitions 13 are located at the upper and lower ends of the partitions 13, respectively. The inlet pipe 11 and the outlet pipe 12 are located between the partitions 13 at both ends of the array and the inner wall of the water tank 1, respectively. The water inlet 14 of the partition 13 next to the inlet pipe 11 is located at the lower end of the partition 13, and the water inlet 14 of the partition 13 next to the outlet pipe 12 is located at the upper end of the partition 13. The spare pipe 4 and the second sleeve pipe 6 are both installed through the partitions 13.

[0057] With this design, the water inlet pipe 11 continuously supplies water to the water tank 1, and the water outlet pipe 12 continuously discharges water from the water tank 1, thus realizing the flow and circulation of cooling water in the water tank 1 and improving the cooling efficiency of the cooling water.

[0058] Preferred, such as Figure 7 and Figure 10 As shown, each inlet pipe 11 is equipped with a seventh valve 15, and each inlet pipe 11 is connected to the same water supply pipe 16. One end of the water supply pipe 16 is closed, and the other end is used to connect with an external cooling water pumping mechanism. Each outlet pipe 12 is connected to the same drain pipe 17. One end of the drain pipe 17 is closed, and the other end is used to connect with an external cooling water storage mechanism.

[0059] This design also allows for the dynamic selection of the number of water tanks 1 to be activated based on the current amount of hot oil that needs to be cooled, thus avoiding excessive waste of cooling water and reducing the energy consumption of pumping cooling water.

[0060] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
