Description

Technical Field

[0001] The present invention relates to the technical field of temperature detection and control, and in particular to a temperature control system and a control method for Sichuan pepper oil. Background Art

[0002] Sichuan peppercorn oil is a common condiment widely used in food processing and cooking. Traditionally, it's prepared using direct flame or steam heating. Rapeseed oil is heated to a suitable temperature before the Sichuan peppercorns are soaked or fried in the oil to extract their flavor components, such as piperine, geraniol, and D-limonene.

[0003] However, this traditional process has the following problems: the heating temperature is difficult to control accurately; the traditional heating method often causes the oil temperature to be too high or too low, affecting the release of flavor substances in the peppercorns. Excessive temperature may destroy the aroma components in the peppercorns and even produce a burnt smell; when the temperature is too low, the efficiency of flavor extraction is reduced, affecting product quality; as disclosed in the patent CN202311055391.2, a temperature control method and system in the refining process of edible animal fats is disclosed, which is also the temperature control of edible oil. In order to be able to accurately control the temperature, it divides the refining container into multiple areas of equal height in the longitudinal direction, calculates the volume and average temperature of each area, calculates the energy required for heating through the temperature difference calculation strategy, and imports the energy and heating power into the heating time planning strategy, and heats according to the calculated heating time and actual heating power.

[0004] At the same time, during the high temperature processing, it will lead to large oil mist loss, low utilization rate of effective ingredients, and part of the oil mist will escape with the steam, resulting in increased oil loss, affecting production efficiency, causing waste of materials to be processed, and increasing production costs.

[0005] Therefore, how to accurately control the oil temperature and increase the flavor extraction rate while reducing oil mist loss and improving processing efficiency has become a core issue of concern to technical personnel in this field. Summary of the Invention

[0051] ,

[0052] Where R represents the oil mist content and η represents the efficiency of the collection unit;

[0053] The second temperature regulating zone and the first temperature regulating zone are also provided with an oil mist detection unit. When the oil mist concentration in the second temperature regulating zone and the first temperature regulating zone is detected to be too high, the feedback control module can reduce the T S Or increase η.

[0054] In the above technical solution, the oil mist concentration is monitored by the oil mist detection unit in the heating and first temperature adjustment zones, and real-time regulation is performed in combination with the efficiency of the collection unit.

[0064] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the examples and accompanying drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0065] Example 1

[0066] like Figures 1 to 3 As shown, this embodiment provides a peppercorn oil temperature control system, comprising:

[0067] The processing module 1 includes a heating unit 51, a supply port is provided at the top of the processing module 1, and a discharge port and a collection port are provided at the bottom of the processing module 1. A mixing module 3 is provided in the processing module 1. The top surface of the processing module 1 also includes an input port, which is connected to the first heating module 2 via an oil supply pipe.

[0068] A temperature detection module is provided on the inner wall of the processing module 1 and is electrically connected to the feedback control module;

[0069] Among them, the temperature detection module is used to monitor the temperature inside the processing module 1 in real time, and feed back the data to the feedback control module through the data transmission module. The feedback control module is used to dynamically adjust the power of the heating unit 51 and the output temperature of the first heating module 2 according to the real-time data of the temperature detection module and the real-time temperature changes in the processing module 1 to achieve closed-loop temperature control.

[0070] like Figure 2 and Figure 3 As shown, a first baffle 14 is provided in the processing module 1, the edge of the first baffle 14 is fixedly connected to the inner wall of the processing module 1, a through hole is opened on the first baffle 14, a sealed bearing is provided in the through hole, the mixing module 3 includes a shaft and a plurality of blades, the plurality of blades are fixedly connected around the shaft, the shaft is provided with sealed bearings located on the upper and lower sides of the first baffle 14, a first valve 141 is provided on the first baffle 14, and the feedback control module is electrically connected to the first valve 141 and controls the opening and closing of the first valve 141.

[0071] like Figure 2 and Figure 3 As shown, a second baffle 15 is further provided in the processing module 1. The second baffle 15 is located below the first baffle 14. A second valve 151 is provided on the second baffle 15. The first baffle 14 and the inner top surface of the processing module 1 form a first temperature adjustment zone 11. A second temperature adjustment zone 12 is formed between the first baffle 14 and the second baffle 15. The second baffle 15 and the inner bottom surface of the processing module 1 form a third temperature adjustment zone 13.

[0072] like Figure 2 and Figure 3 As shown, it also includes a vacuum module 8, a collecting unit 6, a cooling module 7 and a second heating module 5. The vacuum module 8 is connected to the first temperature regulating zone 11 through a vacuum tube, the collecting unit 6 is connected to the first temperature regulating zone 11 through a liquid collecting pipe, the cooling module 7 is connected to the collecting end through an oil drain pipe, the first heating module 2 is connected to the storage module 4 through an oil pipeline, the second heating module 5 is connected to the heating unit 51, and the other end of the heating unit 51 is located in the second temperature regulating zone 12. The feedback control module controls the vacuum module 8, the collecting unit 6, the cooling module 7, the first heating module 2 and the second heating module 5 to perform operations.

[0073] like Figure 2 and Figure 3 As shown, a separation unit is provided in the processing module 1 , and the separation unit is located below the second baffle 15 , and the lowest end of the separation unit is at the same height as the discharge port.

[0074] The temperature detection module is a plurality of temperature sensors, which are spirally wound around the inner wall of the processing module 1 located in the first temperature adjustment zone 11 , the second temperature adjustment zone 12 and the third temperature adjustment zone 13 .

[0075] like Figure 2 and Figure 3 As shown, the first baffle 14 is further provided with an air outlet 142 , the air outlet 142 is provided with a third valve, and a temperature insulating layer is provided in the processing module 1 in the first temperature regulating zone 11 .

[0076] Specifically, the storage module 4 is used to store vegetable oil at room temperature. In the present invention, the vegetable oil is preferably rapeseed oil. During processing, the feedback control module is responsible for controlling the opening of the oil pipeline and the rapeseed oil enters the first heating module 2. Preferably, a temperature sensor is also provided in the first heating module 2 to detect the oil temperature of the rapeseed oil. The heating temperature should be the real-time data fed back to the feedback control module by the temperature sensor. The feedback control module calculates the required temperature. After heating to the required temperature, it is input into the first temperature adjustment zone 11 through the supply end via the oil supply pipe. The feedback control module performs PID calculation through the PID controller, and then the program control unit executes each module and unit in the control system.

[0077] The temperature sensor then detects that after the first temperature adjustment zone 11 is cooled to a certain temperature, the data is fed back to the feedback control module, the input end is opened, and a certain amount of the object to be processed is manually added and mixed with the rapeseed oil. Preferably, the object to be processed in the present invention is fresh peppercorns, and the residue is processed peppercorn fruit. The rapeseed oil in the first temperature adjustment zone 11 is mixed with the fresh peppercorns and cooled to the required temperature again.

[0078] When the temperature sensor in the first temperature regulating zone 11 detects that the mixture of the rapeseed oil and fresh peppercorns reaches the required temperature, the feedback control module receives feedback, opens the first valve 141, and the mixture is input into the second temperature regulating zone 12. Preferably, a level gauge or pressure sensor electrically connected to the feedback control module can also be provided on the first baffle 14 to detect whether the mixture in the first temperature regulating zone 11 is emptied. After the mixture has completely entered the second temperature regulating zone 12, the feedback control module receives a response signal, controls the mixing module 3 and the second heating module 5 to start, and simultaneously controls the opening of the third valve on the air outlet 142.

[0079] The mixing module 3 stirs the mixture of rapeseed oil and fresh peppercorns through blades, and the second heating module 5 transfers heat to the mixture through the heating unit 51 to heat it. Preferably, the second heating module 5 is a steam heating device and the heating unit 51 is a steam pipe, which can better heat the mixture; during the operation of the mixing module 3 and the heating unit 51, the temperature sensor in the second temperature adjustment zone 12 monitors the temperature in real time, and the feedback control module controls the temperature of the mixture within a preset range to maintain the best flavor.

[0080] Preferably, the processing module 1 is also provided with a time monitoring unit for monitoring the processing time of the rapeseed oil at each stage and feeding back the data to the feedback control module. After the rapeseed oil and fresh peppercorns are processed for the required time in the second temperature regulating zone 12, the time monitoring unit feeds back to the feedback control module to control the opening of the second valve 151, and the processed mixture, i.e., the peppercorn oil, is input into the third temperature regulating zone 13. The peppercorn oil is gathered to the bottom surface of the processing module 1 through the separation unit, and is input to the cooling module 7 through the collecting end along the oil drain pipe. Preferably, the separation unit is a screen plate, which can isolate the peppercorns above the screen plate. The cooling module 7 is a cooler, which cools the peppercorn oil to the required temperature and then packs it into boxes; the peppercorn fruits are isolated on the separation unit. After the peppercorn oil is input, it stays for the required time preset by the time monitoring unit, and then the feedback control module opens the discharge port to collect the peppercorn fruits; during the working time of the third temperature adjustment zone 13, the second temperature adjustment zone 12 and the first temperature adjustment zone 11 stop operating, and close the corresponding valves and air outlet 142. The feedback control module can control the system to discharge new rapeseed oil into the first temperature adjustment zone 11 again, that is, at the end of the first processing, the second processing is carried out to improve work efficiency.

[0081] Preferably, the processing module 1 is also provided with a vacuum system, which is connected to the first temperature adjustment zone 11 through a vacuum tube, so that the first temperature adjustment zone 11 and the second temperature adjustment zone 12 can maintain a vacuum state. In the vacuum state, the oil temperature in the processing module 1 rises faster, and the heating efficiency of the heating unit 51 is improved.

[0082] Example 2

[0083] In Example 1, when the heating unit 51 and the mixing module 3 in the second temperature regulating zone 12 are in operation, the Sichuan pepper oil will be exposed to high temperature and produce oil mist, that is, vapor mixed with Sichuan pepper oil. In order to avoid waste, the generated oil mist will be collected in this embodiment.

[0084] Preferably, an oil mist detection unit is also provided in the processing module 1. When it is detected that the oil mist in the second temperature adjustment zone 12 and the first temperature adjustment zone 11 exceeds a certain amount, the feedback control module receives feedback, controls the collection unit 6 to start, and opens the liquid collecting pipe. The collection unit 6 sucks the oil mist through the liquid collecting pipe. After the oil mist enters the collection unit 6, the pepper oil will be extracted and enter the filter bag, which avoids waste.

[0085] It should be noted that when the oil mist concentration is too high, the feedback control module can control the second heating module 5 to reduce the heating power, or control the collection unit 6 to increase the power, thereby reducing the oil mist concentration.

[0086] Example 3

[0087] like Figure 4As shown, this embodiment provides a method for controlling the temperature of Sichuan pepper oil, which realizes temperature control processing based on a Sichuan pepper oil temperature control system according to claim embodiment 1 and embodiment 2, including the following steps:

[0088] S1, inputting normal temperature vegetable oil into the first heating module 2 and heating it to a first preset temperature, inputting the vegetable oil heated to the first preset temperature into the first temperature adjustment zone 11, and then adding the object to be processed through the supply end;

[0089] S2, cooling the vegetable oil and the object to be processed in the first temperature adjustment zone 11 to a second preset temperature;

[0090] S3, inputting the vegetable oil and the object to be processed after being cooled to the second preset temperature into the second temperature adjustment zone 12, and heating the vegetable oil and the object to be processed input into the second temperature adjustment zone 12 to a third preset temperature to obtain a semi-finished product and a residue;

[0091] S4, inputting the semi-finished product and the residue into the third temperature adjustment zone 13;

[0092] S5. Discharge the semi-finished product in the third temperature adjustment zone 13 to the cooling module 7 through the oil discharge pipe, and discharge the residue out of the processing module 1 through the discharge pipe;

[0093] S6, cooling the semi-finished product input to the cooling module 7 to a fourth preset temperature to obtain a finished product;

[0094] S7, while the residue is being discharged from the processing module 1, continue to execute S1;

[0095] S8. Repeat S2-S7 to produce and process finished oil products.

[0096] The vegetable oil and the object to be processed input into the second temperature regulating zone 12 are heated to the third preset temperature for a heating time that is the first preset time, and the mixing module 3 operates while heating.

[0097] The time length for the residue in the third temperature regulating zone 13 to be discharged from the processing module 1 is the second preset time length.

[0098] The temperature control method for the production and processing of refined oil products also includes:

[0099] The temperature value of the first temperature regulating zone 11 is detected by a temperature sensor, and the feedback control module adjusts the first preset temperature when the vegetable oil is input into the first temperature regulating zone 11 in response to the temperature value of the first temperature regulating zone 11 .

[0100] The feedback control module adjusts the first preset temperature according to the following method:

[0101] ,

[0102] Wherein, T1 represents the first preset temperature, T represents the optimal temperature at which the vegetable oil at the first preset temperature can be put into the first temperature adjustment zone 11 after cooling, and T H represents the temperature of the processing module 1 in the first temperature adjustment zone 11, m H 、c H They represent the mass and specific heat capacity of the processing module 1 in the first temperature adjustment zone 11, m o 、c o They respectively represent the mass and specific heat capacity of the vegetable oil entering the first temperature adjustment zone 11.

[0103] The first preset temperature is 150°C-250°C, the second preset temperature is 100°C, the third preset temperature is 110°C-220°C, and the first preset time is 20-40 minutes.

[0104] Specifically, in the present invention, in order to control the peppercorn oil to meet the flavor requirements, the temperature of each processing step is monitored and controlled by a temperature sensor and a feedback control module; in the present invention, the first preset temperature is 150℃-250℃, the second preset temperature is 100℃, the third preset temperature is 110℃-220℃, the first preset time is 20-40min, the rapeseed oil is at room temperature of 25℃, and the quantitative amount added each time is 300kg, the fresh peppercorn is at room temperature of 25℃, and the quantitative amount added each time is 100kg, the cooling module 7 cools the peppercorn oil to the fourth preset temperature, i.e. 100℃-150℃; the second preset time is 20-40min, and it can also be selected to take it out directly after the finished oil is discharged, or to use the heat conduction of the second temperature adjustment zone 12 to dry the residue during the second processing, and the drying time at this time should be less than the minimum value of the first preset time.

[0105] In the temperature control method of this embodiment, the above formula is to control the power of the first heating module 2 at the optimal temperature T, so that the first preset temperature T1 is not only within the preset reasonable temperature range, but also can be quickly cooled to the optimal temperature T; after the rapeseed oil is heated to the first preset temperature by the first heating module 2 and input into the first temperature adjustment zone 11, it needs to be cooled to the optimal temperature T. Fresh peppercorns are added at the optimal temperature T. The oil temperature of the rapeseed oil can fully release the numbing substances in the fresh peppercorns to obtain the best flavor. The optimal temperature T is obtained through multiple experiments and is 120°C-130°C. After the heated rapeseed oil enters the first temperature adjustment zone 11, it will change according to the specific heat capacity of the first temperature adjustment zone 11. Therefore, the first preset temperature T1 must be higher than the optimal temperature T;

[0106] Preferably, in the second and subsequent processing, since the first temperature adjustment zone 11 has been cooled and the second temperature adjustment zone 12 has been heated to generate oil mist release, the specific heat capacity of the first temperature adjustment zone 11 is relatively high relative to the first processing, and the optimal temperature T is determined according to the type of fresh peppercorns added, and the temperature value is constant. Therefore, after the temperature sensor detects the temperature of the first temperature adjustment zone 11, the feedback control module can reduce the power of the first heating module 2 in the second and subsequent processing according to the relationship of the above formula, that is, reduce the first preset temperature, and allow the rapeseed oil to cool to the optimal temperature T faster and add fresh peppercorns, further increasing production efficiency. At the same time, the power of the first heating module 2 is appropriately reduced, and the cost is correspondingly reduced.

[0107] Example 4

[0108] In this embodiment, the mixture of rapeseed oil and fresh pepper at the second preset temperature obtained in Example 3 is input into the second temperature adjustment zone 12, and the second temperature adjustment zone 12 is heated to the third preset temperature by the heating unit 51. The relationship change of the third preset temperature is expressed as follows:

[0109] ,

[0110] Wherein, T3 represents the third preset temperature, T2 represents the second preset temperature, T S represents the heating temperature of the heating unit 51, and t represents the heating time at the third preset temperature.

[0111] The above formula represents the temperature rising process of the third preset temperature, that is, as the heating time t changes, the third preset temperature T3 also changes. As T3 gradually increases, the oil mist content in the current processing module 1 increases.

[0112] The third preset temperature T3 in the above formula is related to the heating temperature T of the heating unit. S Wherein, k1 represents the heating rate of the heating unit 51 and is a constant in the above formula. The expression of k1 is:

[0113] ,

[0114] In the above formula, h represents the heat transfer coefficient of the heating unit 51, A represents the heat transfer area of ​​the heating unit 51, and c Z It represents the specific heat capacity of the second temperature adjustment zone 12. These parameters are usually determined and the corresponding parameters can be accurately obtained. Preferably, the parameters of k1 can be changed by replacing different heating units 51 before processing according to actual operation. This formula is mainly used to determine the heating efficiency of the heating unit 51.

[0115] When k1 is large, the heating temperature T of the heating unit 51 SAs the temperature increases, the third preset temperature T3 also increases, which also indicates that the amount of oil mist in the second temperature adjustment zone 12 and the first temperature adjustment zone 11 is relatively large.

[0116] The vegetable oil in the second temperature regulating zone 12 is heated by the heating unit 51 to generate oil mist. The oil mist content in the second temperature regulating zone 12 and the first temperature regulating zone 11 is expressed as:

[0117] ,

[0118] Wherein, R represents the oil mist content, and η represents the efficiency of the collection unit 6;

[0119] This formula is mainly used to determine the oil mist content in the processing module 1. The change in the oil mist content is related to the temperature rise change process formula of the third preset temperature, that is, the third preset temperature T3, and is also related to the capture efficiency of the collection unit 6.

[0120] The second temperature regulating zone 12 and the first temperature regulating zone 11 are provided with an oil mist detection unit. When the oil mist concentration in the second temperature regulating zone 12 and the first temperature regulating zone 11 is detected to be too high, the feedback control module can reduce the T S Or increase η.

[0121] Specifically, the oil mist detection unit is preferably a laser particle counter or a light scattering instrument, and is set at a height much higher than the maximum liquid level in the second temperature adjustment zone 12. In the above formula, n represents the nonlinear relationship between oil mist generation and the gradual increase of the third preset temperature, k2 represents the oil mist generation rate, n and k2 are related to the third preset temperature T3, and the temperature range of T3 is fixed, which is 110°C-220°C. On this basis, n and k2 are measured through preliminary simulation experiments and recorded in the feedback control module. When the third preset temperature, the material of the oil and the processing module 1 are determined, n and k2 are also determined. The feedback control module obtains the current oil mist content based on the feedback data, and chooses to increase the efficiency of the collection unit 6 or reduce the temperature of the heating unit 51 according to the above formula according to the actual situation; for example, when the temperature sensor detects that the temperature of the pepper oil in the second temperature adjustment zone 12 is close to the maximum critical value of the third preset temperature, the efficiency of the collection unit 6 can be increased; otherwise, the temperature of the heating unit 51 is increased for adaptive adjustment.

[0122] Through the temperature control method described above, rapeseed oil and peppercorns can maintain appropriate processing temperatures at various nodes, thereby improving efficiency, reducing costs and obtaining better finished products.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
