It realizes the comprehensive and accurate monitoring of the production process of hot pot base materials.

[0003] The existing processing technologies have the following problems: it is not convenient to control the water content of the base materials, and it is difficult to reduce the harmful substances generated during the processing.

[0004] Based on the above situation, there is an urgent need for a method and equipment for controlling the processing of base materials to solve the problems of inconvenient control of the water content of the base materials and difficulty in reducing the harmful substances generated during the processing. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of inconvenient control of the water content of the base materials and difficulty in reducing the harmful substances generated during the processing for the existing processing equipment.

[0006] On the one hand, the present invention provides a method for controlling the processing of base materials, including:

[0007] After heating oil with a pot body, adding n types of raw materials into the pot body step by step according to types for processing;

[0008] Respectively setting corresponding humidity thresholds RH i and particulate matter concentration thresholds P i ;

[0009] During the processing, the air in the pot body is detected to obtain measurement data, and the measurement data includes at least humidity RH and particulate matter concentration P ;

[0010] If the humidity measurement value RH is greater than the corresponding humidity threshold RH i , the processing time is increased;

[0011] If the particulate matter concentration measurement value P is greater than the corresponding particulate matter concentration threshold P i , the processing temperature is decreased;

[0012] If the humidity measurement value RH is less than the humidity threshold RH i and the particulate matter concentration measurement value P is greater than the particulate matter concentration threshold P i , the processing of the corresponding type of raw material is completed, and the next type of raw material is added to the pot body;

[0013] Wherein n is a positive integer, i = 1, 2, 3... n .

[0014] The existing processing equipment has the following problems: it is not convenient to control the water content of the base material, and it is difficult to reduce the harmful substances generated during the processing. In this solution, by continuously measuring the air in the pot body during the processing, the water content of the corresponding raw material is reflected by the humidity threshold RH i . When the humidity measurement value RH is less than the humidity threshold RH i , it indicates that the water content of this type of raw material has been less than the preset value. Since the raw material will decompose to produce particulate matter and other harmful substances after being overheated, when the particulate matter concentration measurement value P is greater than the particulate matter concentration threshold P i , it indicates that this type of raw material is about to produce excessive harmful substances. It is possible to reduce the water content of this type of raw material to below the preset value before excessive harmful substances are produced by the decomposition of this type of raw material, and then continue to process the next type of raw material, solving the problems of inconvenient control of the water content of the base material and difficulty in reducing the harmful substances generated during the processing. By reducing the water content of the raw material to below the preset value, the corruption of the raw material can be delayed, thereby extending the storage time.

[0015] Further, in order to reduce the generation of particulate matter during the entire processing, one feasible solution is: setting corresponding humidity thresholds according to different types of raw materials RH i and particulate matter concentration thresholds P i , including:

[0016] Adding a specified type of raw material independently during the trial processing;

[0017] Calculating the corresponding humidity threshold of the raw material RH i ;

[0018] Calculating the corresponding particulate matter concentration threshold of the raw material P i ;

[0019] Controlling the processing order of different types of raw materials according to the particulate matter concentration threshold P i .

[0020] When adopting this solution, a raw material with a higher particulate matter concentration threshold P i reflects that more harmful substances are generated during the processing of this type of raw material. Then, the processing order is postponed, thereby reducing the total processing time of this type of raw material, reducing the generation of particulate matter during the entire processing, and reducing the generation of harmful substances.

[0021] Further, this solution does not uniquely limit the calculation method of the humidity threshold RH i , and one feasible solution is: calculating the corresponding humidity threshold of the raw material RH i , including:

[0022] Heating the oil to a temperature above the first temperature;

[0023] Adding a specified type of raw material into the pot body;

[0024] Continuously measuring the air humidity in the pot body;

[0025] If the humidity change amount within a time period is less than 20%, then calculate the average humidity within this time period as the humidity threshold RH i .

[0026] When adopting this solution, if the change amount of the air humidity in the pot body within a time period is less than 20%, it means that the evaporation amount of the raw material during the processing is less and the water content is already low enough. By taking the average humidity within this time period as the humidity threshold RH i, which is convenient for controlling the processing time of raw materials.

[0027] Furthermore, due to the different water contents of raw materials, to reduce the interference of environmental changes on raw materials with low water content, one feasible solution is: before adding the specified type of raw materials into the pot body, measure the water content of the raw materials;

[0028] If the water content of the raw materials is less than 10%, when the humidity change amount within a time period is less than 10%, calculate the average humidity value within this time period as the humidity threshold RH i .

[0029] When adopting this solution, for raw materials with low water content, the requirement for the change amount of evaporation is small, which can reduce the interference of environmental changes on raw materials with low water content to ensure that the water content of the raw materials is reduced to below the preset value.

[0030] Furthermore, this solution does not uniquely limit the calculation method of the particulate matter concentration threshold P i One feasible solution is: calculating the particulate matter concentration threshold corresponding to the raw materials, P i , including:

[0031] Heat the oil to above the second temperature;

[0032] After adding the specified type of raw materials into the pot body, continue heating and continuously measure the particulate matter concentration in the air in the pot body;

[0033] Sample the air in the pot body at several moments in a fixed cycle and analyze the concentration of harmful substances corresponding to each moment. The concentration of harmful substances at least includes the concentration of polycyclic aromatic hydrocarbon compounds;

[0034] If the concentration of one of the harmful substances exceeds the preset value, calculate the average particulate matter concentration within the first cycle before the corresponding moment as the particulate matter concentration threshold P i .

[0035] When adopting this solution, if after one cycle of processing, due to the high heating temperature, the air particulate matter concentration in the pot body decomposes to produce particulate matter and harmful substances, resulting in the concentration of harmful substances exceeding the preset value, it is necessary to reduce the heating temperature by using the average particulate matter concentration within this cycle as the particulate matter concentration threshold P i , which is convenient for controlling the processing temperature of raw materials.

[0036] Furthermore, this solution does not uniquely limit the particulate matter concentration threshold P iMethod for associating with processing sequence, according to the particulate matter concentration threshold P i Control the processing sequence of different types of raw materials, including:

[0037] Divide the raw materials into dry raw materials and wet raw materials according to the water content of the raw materials;

[0038] Add the wet raw materials step by step according to the types into the pot body for processing;

[0039] After all the wet raw materials are processed, add the dry raw materials step by step according to the types into the pot body for processing;

[0040] From the particulate matter concentration threshold P i Add the dry raw materials or wet raw materials in ascending order.

[0041] When adopting this scheme, after all the wet raw materials are processed, then process the dry raw materials. The wet raw materials can be further dehydrated during the processing of the dry raw materials to ensure that the water content of the wet raw materials is low enough. For raw materials with a relatively high particulate matter concentration threshold P i Delay the processing sequence, which can reduce the generation of particulate matter during the whole processing process, and thus reduce the generation of harmful substances.

[0042] On the other hand, the present invention also provides a bottom material processing device, including:

[0043] A pot body, in which a heating plate is arranged;

[0044] Several feeding units, arranged above the pot body;

[0045] A humidity sensor, installed on the pot body;

[0046] A particulate matter concentration sensor, installed on the pot body.

[0047] When adopting this scheme, measure the humidity RH and particulate matter concentration P respectively through the humidity sensor and the particulate matter concentration sensor, so as to control the feeding unit to add the corresponding raw materials into the pot body.

[0048] Furthermore, the specific structure of the feeding unit is not uniquely limited in this scheme. One feasible scheme is that the feeding unit includes a storage barrel, and a feeding valve is installed at the lower end of the storage barrel. When adopting this scheme, by pre-quantitatively storing various raw materials in the storage barrel, after opening the feeding valve, it is convenient for the raw materials in the corresponding storage barrel to fall into the pot body.

[0049] Furthermore, the present solution does not solely limit the specific structure of the particle concentration sensor. One feasible solution is: the particle concentration sensor includes a detection channel, in which a laser emitter and a receiving plate are provided. When this solution is adopted, the air in the pot body expands due to heat, resulting in a decrease in density. Under the action of buoyancy, the air passes through the detection channel from bottom to top. When the particulate matter carried in the air passes between the laser emitter and the receiving plate, the laser is scattered. The scattered light is received by the receiving plate and analyzed, so that the particle concentration value can be obtained conveniently and quickly.

[0050] Furthermore, in order to automate the feeding, one feasible solution is: the feeding valve is an electric valve and the feeding valve is jointly controlled by a humidity sensor and a particle concentration sensor. When this solution is adopted, the feeding valve is controlled by feedback from the humidity sensor and the particle concentration sensor so that the corresponding feeding valve can be opened when the preset conditions are met, thereby realizing automatic feeding.

[0051] Compared with the existing technology, the beneficial effects of the present invention are:

[0052] 1. By continuously measuring the air in the pot during the processing, the humidity threshold RH i Reflects the moisture content of the corresponding raw material. When the humidity measurement value RH Less than humidity threshold RH i When the water content of the raw material is less than the preset value, the raw material will decompose and produce particles and other harmful substances after overheating. P Greater than the particle concentration threshold P i When the water content of the raw material is about to produce too many harmful substances, it indicates that the raw material is about to produce too many harmful substances. The water content of the raw material can be reduced to below the preset value before the raw material decomposes and produces too many harmful substances. Then, the next raw material can be processed. This solves the problem of being difficult to control the water content of the base material and difficult to reduce the harmful substances produced during the processing. By reducing the water content of the raw material to below the preset value, the corruption of the raw material can be delayed, thereby extending the storage time.

[0053] 2. If the concentration of air particles in the pot exceeds the preset value after a cycle of processing, due to the high heating temperature, the particles and harmful substances are decomposed by heat, and the concentration of harmful substances exceeds the preset value, the heating temperature needs to be reduced, and the average particle concentration in the cycle is used as the particle concentration threshold. P i , which is convenient for controlling the processing temperature of raw materials;

[0054] III. After all wet raw materials are processed, the dry raw materials are processed. The wet raw materials can be further dehydrated during the processing of the dry raw materials to ensure that the water content of the wet raw materials is low enough, and the particulate matter concentration threshold P i For raw materials with a relatively high BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The features and performance of the present invention will be further described in detail below in conjunction with the embodiments.

[0063] Embodiment 1:

[0064] Please refer to Figure 1 , a method for controlling the processing of the base material, comprising:

[0065] S100. After heating the oil with the pot body, add n types of raw materials to the pot body step by step according to the types for processing;

[0066] S200, set corresponding humidity thresholds according to different types of raw materials RH i and particulate matter concentration thresholds P i ;

[0067] S300: During the processing, the air in the pot is detected to obtain measurement data, which at least includes humidity. RH and particulate matter concentration P ;

[0068] S400, if humidity measurement value RH Greater than the corresponding humidity threshold RH i , then the processing time will be increased;

[0069] S500, if the particle concentration measurement value P Greater than the corresponding particle concentration threshold P i , then reduce the processing temperature;

[0070] S600, if humidity measurement value RH Less than humidity threshold RH i And the particle concentration measurement value P Greater than the particle concentration threshold P i , the processing of the corresponding type of raw materials is completed, and the next type of raw materials is added to the pot;

[0071] in n is a positive integer, i =1, 2, 3... n .

[0072] The existing processing equipment has the following problems: it is not easy to control the moisture content of the base material, and it is difficult to reduce the harmful substances produced during the processing. In this solution, the air in the pot is continuously measured during the processing, and the humidity threshold is used to determine the water content of the base material. RH i Reflects the moisture content of the corresponding raw material. When the humidity measurement value RH Less than humidity threshold RH i When the water content of the raw material is less than the preset value, the raw material will decompose and produce particles and other harmful substances after overheating. P Greater than the particle concentration threshold P iWhen the water content of the raw material is reduced to below the preset value before it decomposes and produces too many harmful substances, the next raw material can be processed. This solves the problem of being inconvenient to control the water content of the base material and difficult to reduce the harmful substances produced during the processing. By reducing the water content of the raw material to below the preset value, the corruption of the raw material can be delayed, thereby extending the storage time.

[0073] In order to reduce the generation of particulate matter during the entire processing process, one feasible solution is: S200, set the corresponding humidity threshold according to different types of raw materials RH i and particulate matter concentration thresholds P i ,include:

[0074] S210, independently adding designated types of raw materials during the trial processing;

[0075] S220: Calculate the humidity threshold corresponding to the raw material RH i ;

[0076] S230: Calculate the particle concentration threshold corresponding to the raw material P i ;

[0077] S240, based on the particle concentration threshold P i Control the processing sequence of different types of raw materials.

[0078] When this solution is adopted, the particle concentration threshold P i Higher raw materials reflect that more harmful substances are produced during the processing of this raw material. Therefore, the processing sequence should be postponed, thereby reducing the total processing time of this raw material, thereby reducing the generation of particulate matter during the entire processing process, and thus reducing the generation of harmful substances.

[0079] This solution does not uniquely define the humidity threshold RH i A calculation method, one of which is feasible: S220, calculate the humidity threshold corresponding to the raw material RH i ,include:

[0080] S221, heating the oil to a temperature above a first temperature. Specifically, in this embodiment, the first temperature is t-80° C., where t is the boiling point of the oil and “-” is a minus sign.

[0081] S222, adding specified types of raw materials into the pot;

[0082] S223, continuously measuring the air humidity in the pot;

[0083] S224. If the humidity change within a time period is less than 20%, calculate the average humidity within this time period as the humidity threshold. RH i .

[0084] When adopting this scheme, if the change in air humidity in the pot body within a time period is less than 20%, it indicates that the evaporation amount of the raw material during the processing is small and the water content is already low enough. By taking the average humidity within this time period as the humidity threshold RH i , it is convenient to control the processing time of the raw material.

[0085] Due to the different water contents of raw materials, to reduce the interference of environmental changes on raw materials with low water content, one feasible scheme is: before adding the specified type of raw material into the pot body, measure the water content of the raw material;

[0086] If the water content of the raw material is less than 10%, when the humidity change within a time period is less than 10%, calculate the average humidity within this time period as the humidity threshold RH i .

[0087] When adopting this scheme, for raw materials with low water content, the requirement for the change amount of evaporation is small, which can reduce the interference of environmental changes on raw materials with low water content to ensure that the water content of the raw material is reduced below the preset value.

[0088] This scheme does not uniquely limit the calculation method of the particulate matter concentration threshold P i One feasible scheme is: S230. Calculate the particulate matter concentration threshold corresponding to the raw material P i , including:

[0089] S231. Heat the oil to a temperature above the second temperature. Specifically, in this embodiment, the value of the second temperature is t - 50°C, where "-" is the minus sign;

[0090] S232. After adding the specified type of raw material into the pot body, continue heating and continuously measure the particulate matter concentration in the air in the pot body;

[0091] S233. Take samples of the air in the pot body at several moments (exemplarily, the period is 2 minutes, and the sampling times are the 2nd minute, the 4th minute, the 6th minute...) at a fixed period, and analyze the harmful substance concentration corresponding to each moment. The harmful substance concentration at least includes the concentration of polycyclic aromatic hydrocarbon compounds;

[0092] S234. If the concentration of one of the harmful substances exceeds the preset value, calculate the average value of the particulate matter concentration in the first cycle before the corresponding moment as the particulate matter concentration threshold. P i ; Exemplarily, if it is detected at the 4th minute that the concentration of any harmful substance exceeds the preset value, then the average value of the particulate matter concentration in the cycle from the 2nd minute to the 4th minute is used as the particulate matter concentration threshold. P i .

[0093] When adopting this scheme, if after one cycle of processing, due to the high heating temperature, the air particulate matter concentration in the pot body decomposes to produce particulate matter and harmful substances, resulting in the concentration of harmful substances exceeding the preset value, then it is necessary to reduce the heating temperature by using the average particulate matter concentration in this cycle as the particulate matter concentration threshold. P i This is convenient for controlling the processing temperature of the raw materials.

[0094] This scheme does not uniquely define the method for analyzing the concentration of harmful substances. One feasible scheme is as follows: During multiple processing processes, air in the pot body is sampled at several moments in a fixed cycle, and the concentration of harmful substances corresponding to each moment is analyzed. Specifically, gas chromatography is used to separate the organic substances in the sample, and 80% of the particulate matter concentration corresponding to the moment when the concentration of any harmful substance is detected by mass spectrometry is used as the correction value. If the correction value is lower than the particulate matter concentration threshold. P i , then the particulate matter concentration threshold P i is updated to the correction value. When adopting this scheme, during the batch bottom material processing process, the types and proportions of the raw materials are relatively fixed. Therefore, the processing sequence obtained from the trial processing process is also relatively fixed. The raw materials added first will decompose together with the later added raw materials under heat to produce particulate matter and other harmful substances. So the interference of the raw materials added first to the particulate matter concentration threshold P i of the currently added raw materials is also relatively fixed. By correcting the particulate matter concentration threshold P i , it is possible to sequentially and quickly eliminate the interference of the raw materials added first to the particulate matter concentration threshold P i corresponding to the currently added raw materials, and thus it is possible to more quickly optimize the control method and gradually reduce the generation of harmful substances during the entire processing process.

[0095] This scheme does not uniquely define the association method between the particulate matter concentration threshold P i and the processing sequence. S240. According to the particulate matter concentration threshold P iControl the processing sequence of different types of raw materials, including:

[0096] S241. Divide the raw materials into dry raw materials and wet raw materials according to their moisture content;

[0097] S242. Add the wet raw materials into the pot body step by step according to their types for processing;

[0098] S243. After all the wet raw materials are processed, add the dry raw materials into the pot body step by step according to their types for processing;

[0099] S244. Add the dry raw materials or wet raw materials in ascending order according to the particulate matter concentration threshold P i from low to high.

[0100] When adopting this scheme, after all the wet raw materials are processed, then process the dry raw materials. The wet raw materials can be further dehydrated during the processing of the dry raw materials to ensure that the moisture content of the wet raw materials is low enough. For the raw materials with a relatively high particulate matter concentration threshold P i postpone the processing sequence, which can reduce the generation of particulate matter during the whole processing process, and thus reduce the generation of harmful substances.

[0101] Embodiment 2:

[0102] Refer to Figure 2 and Figure 3 , a base material processing device, including:

[0103] A pot body 100, with a heating plate arranged inside the pot body 100;

[0104] Several feeding units 200, arranged above the pot body 100;

[0105] A humidity sensor 300, installed on the pot body 100;

[0106] A particulate matter concentration sensor 400, installed on the pot body 100.

[0107] When adopting this scheme, measure the humidity RH and particulate matter concentration P respectively through the humidity sensor 300 and the particulate matter concentration sensor 400, so as to control the feeding unit 200 to add the corresponding raw materials into the pot body.

[0108] This scheme does not uniquely limit the specific structure of the feeding unit 200. One feasible scheme is that the feeding unit 200 includes a storage barrel 201, and a feeding valve 202 is installed at the lower end of the storage barrel 201. When adopting this scheme, by pre - quantifying and storing various raw materials in the storage barrel 201, after opening the feeding valve 202, it is convenient for the raw materials in the corresponding storage barrel 201 to fall into the pot body.

[0109] The specific structure of the particulate matter concentration sensor 400 is not uniquely defined in this solution. One feasible solution is as follows: The particulate matter concentration sensor 400 includes a detection channel, in which a laser emitter and a receiving plate are arranged. When this solution is adopted, the air in the pot body 100 is heated and expands, resulting in a decrease in density. Under the action of buoyancy, it passes through the detection channel from bottom to top. When the particulate matter carried in the air passes between the laser emitter and the receiving plate, the laser is scattered. The receiving plate receives the scattered light and analyzes it, enabling the particulate matter concentration value to be obtained conveniently and quickly.

[0110] For automatic feeding, one feasible solution is as follows: The feeding valve 202 is an electric valve and is jointly controlled by the humidity sensor 300 and the particulate matter concentration sensor 400. When this solution is adopted, the feeding valve 202 is feedback-controlled by the humidity sensor 300 and the particulate matter concentration sensor 400, so as to open the corresponding feeding valve 202 under the preset conditions and achieve automatic feeding.

[0111] To solve the problems of inconvenient control of the water content of the base material and difficulty in reducing the harmful substances generated during the processing, in this solution, by continuously measuring the air in the pot body during the processing, and through the humidity threshold RH i reflecting the water content of the corresponding raw material, when the humidity measurement value RH is less than the humidity threshold RH i it indicates that the water content of this raw material has been less than the preset value. Since the raw material will decompose to produce particulate matter and other harmful substances after being overheated, when the particulate matter concentration measurement value P is greater than the particulate matter concentration threshold P i it indicates that this raw material is about to produce excessive harmful substances. It is possible to reduce the water content of this raw material to below the preset value before it decomposes to produce excessive harmful substances, and then continue to process the next raw material, solving the problems of inconvenient control of the water content of the base material and difficulty in reducing the harmful substances generated during the processing. By reducing the water content of the raw material to below the preset value, the corruption of the raw material can be delayed, thereby extending the storage time;

[0112] To facilitate the control of the processing temperature, in this solution, if the particulate matter concentration of the air in the pot body, after a cycle of processing, due to the high heating temperature, decomposes to produce particulate matter and harmful substances, resulting in the harmful substance concentration exceeding the preset value, then the heating temperature needs to be reduced. By using the average particulate matter concentration within this cycle as the particulate matter concentration threshold P i it is convenient to control the processing temperature of the raw material;

[0113] In order to reduce the generation of particulate matter during the entire processing, in this solution, after all wet raw materials are processed, the dry raw materials are processed. The wet raw materials can be further dehydrated during the processing of the dry raw materials to ensure that the water content of the wet raw materials is low enough, and the particulate matter concentration threshold P i For raw materials with a relatively high
