Description

Technical Field

[0001] The invention relates to the field of soybean wax processing, and in particular to refining equipment for environmentally friendly soybean wax processing. Background Art

[0002] As people's awareness of environmental protection increases and consumers' demand for healthy and environmentally friendly products grows, traditional petroleum-based paraffin wax is gradually replaced by more environmentally friendly products, which has promoted the development of the market for environmentally friendly candles such as soy wax. At the same time, with the development of technology, the processing and preparation technology of soy wax is also constantly improving, which has greatly improved the performance and quality of soy wax to meet the needs of more application scenarios.

[0003] Chinese Patent Publication No.: CN113201408A discloses a novel soybean wax and a preparation method and application thereof, and relates to the technical field of soybean wax. The novel soybean wax comprises the following raw materials in parts by weight: 70-80 parts of hydrogenated soybean oil, 10-50 parts of hydrogenated vegetable oil, and 1-10 parts of mono- and di-glycerol fatty acid esters. The novel soybean wax preparation method comprises the following steps: heating and melting hydrogenated soybean oil, adding hydrogenated vegetable oil, mixing and stirring, heating to react, then cooling, adding mono- and di-glycerol fatty acid esters, stirring evenly, and cooling to obtain the novel soybean wax.

[0004] However, the prior art still has the following problems: during the hydrogenation heating stage, improper control of the heating rate may cause local overheating and generate bubbles that affect the uniformity of the oil mixture; at the same time, the excessively high air pressure in the stirring chamber causes the reaction rate to be too fast, thereby affecting the effect of the hydrogenation heating and reducing the stability and quality of the soybean wax. Summary of the invention

[0005] To this end, the present invention provides an environmentally friendly refining equipment for soybean wax processing, which is used to overcome the problems in the prior art that in the hydrogenation heating stage, improper control of the heating rate may cause local overheating and generate bubbles that affect the uniformity of the mixed oil, and at the same time, the high air pressure in the stirring chamber causes the reaction rate to be too fast, thereby affecting the effect of hydrogenation heating and reducing the stability and quality of the soybean wax.

[0006] To achieve the above object, the present invention provides an environmentally friendly soybean wax processing refining equipment, which comprises:

[0007] A mixing mechanism, comprising a mixing chamber provided with a mixing space, an air pressure control unit arranged in the mixing chamber for controlling the air pressure in the chamber, a heating unit arranged in the mixing chamber for heating, and a stirring rod for stirring;

[0008] A detection module, comprising an air pressure detection unit disposed in the mixing chamber for detecting the air pressure in the chamber and an image detection unit for detecting an image of a surface of the mixture;

[0009] A host computer, which is connected to the mixing mechanism and the detection module respectively, and includes a state analysis unit and a process control unit;

[0010] The state analysis unit extracts hydrogenation characteristics based on the mixture surface image, and calculates hydrogenation stability characteristics parameters in combination with stirring pressure to classify the stability tendency of hydrogenation heating, wherein the hydrogenation characteristics include bubble coverage area and mixture brightness;

[0011] The process control unit is used to control the mixing mechanism to heat the mixture based on the stable tendency category of hydrogenation heating, including:

[0012] Constructing a time domain curve of the gas pressure change in the chamber, judging whether the hydrogenation heating meets the standard according to the difference in slope between each curve segment and the adjacent curve segment, so as to control the heating rate of the heating unit and the gas pressure in the chamber of the stirring chamber according to the hydrogenation stability characterization parameter;

[0013] Alternatively, the heating unit is controlled to maintain the initial heating rate.

[0014] Furthermore, the state analysis unit calculates the hydrogenation stability characterization parameter according to formula (1):

[0015]

[0016] In formula (1), H represents the hydrogenation stability characterization parameter, S represents the bubble coverage area, S0 represents the preset bubble coverage area standard threshold, C represents the mixture brightness, C0 represents the preset mixture brightness standard threshold, Pi represents the stirring pressure detected for the i-th time, ΔP represents the average stirring pressure of the hydrogenation heating process, and n represents the number of stirring pressure detections during the hydrogenation heating process.

[0017] Furthermore, the state analysis unit divides the stable tendency categories of hydrogenation heating into the following categories:

[0018] If the hydrogenation stability characterization parameter is greater than or equal to the preset hydrogenation stability characterization standard threshold, the stability tendency category of hydrogenation heating is determined to be a weak stability tendency category;

[0019] If the hydrogenation stability characterization parameter is less than a preset hydrogenation stability characterization standard threshold, the stability tendency category of hydrogenation heating is determined to be a strong stability tendency category.

[0020] Furthermore, the process control unit controls the mixing mechanism to heat the mixture, including:

[0021] If the stability tendency category of hydrogenation heating is a weak stability tendency category, a time-domain change curve of the gas pressure in the chamber is constructed, and whether the hydrogenation heating meets the standard is determined according to the difference in slope between each curve segment and the adjacent curve segment, so as to control the heating rate of the heating unit and the gas pressure in the chamber of the stirring chamber according to the hydrogenation stability characterization parameter;

[0022] If the stability tendency category of the hydrogenation heating is a strong stability tendency category, the heating unit is controlled to maintain the initial heating rate.

[0023] Furthermore, the process control unit constructs a time domain change curve of the air pressure in the bin, including:

[0024] Acquiring the air pressure data in the warehouse collected by the air pressure detection unit;

[0025] A rectangular coordinate system is constructed with time as the horizontal axis and the air pressure in the warehouse as the vertical axis;

[0026] Marking the coordinate points of the air pressure in the warehouse at each moment in the rectangular coordinate system;

[0027] The coordinate points are connected with a smooth curve to obtain the time domain variation curve of the air pressure in the warehouse.

[0028] Furthermore, the process control unit calculates the slope difference between the curve segment and the adjacent curve segment, including:

[0029] The process control unit is used to determine the average slope of each curve segment, and compare the average slope of each curve segment with the average slope of an adjacent curve segment to calculate a slope difference.

[0030] Furthermore, the process control unit determines whether the hydrogenation heating meets the standard, including:

[0031] If the difference in slope between a curve segment and an adjacent curve segment is less than the standard threshold value of the slope difference, it is determined that the hydrogenation heating meets the standard.

[0032] Further, the process control unit controls the heating rate of the heating unit, including:

[0033] The heating rate is reduced, and the reduction value of the heating rate is positively correlated with the hydrogenation stability characterization parameter.

[0034] Furthermore, the process control unit controls the gas pressure in the mixing bin, including:

[0035] The gas pressure in the bin is reduced, and the reduction value of the gas pressure in the bin is positively correlated with the hydrogenation stability characterization parameter.

[0036] Furthermore, it also includes a display module, which is connected to the detection module to display the data detected by the detection module.

[0037] Compared with the prior art, the present invention sets a mixing mechanism, a detection module and a host computer, performs heating and stirring operations through the mixing mechanism, the detection module detects the air pressure in the stirring chamber and the surface image of the mixture, the host computer extracts the hydrogenation characterization features based on the surface image of the mixture and calculates the hydrogenation stability characterization parameters in combination with the stirring pressure, divides the stable tendency categories of hydrogenation heating, and then adaptively controls the mixing mechanism to heat the mixture. Through the above process, the present invention can improve the hydrogenation heating effect and ensure the stability and quality of soybean wax.

[0038] In particular, the present invention constructs a state analysis unit, extracts hydrogenation characterization features based on the surface image of the mixture, and calculates hydrogenation stability characterization parameters in combination with stirring pressure. During the hydrogenation heating stage, bubbles are generated due to the influence of hydrogenation reaction and stirring. More bubbles increase the contact area between the mixture and the air, accelerating the oxidation process of the mixture. In particular, the above problems will be aggravated when the hydrogenation reaction is in a violent reaction stage. Moreover, if the heating temperature is too high or the heating is uneven, it may cause local overheating of the oil, which will also form bubbles and affect the uniformity of the mixture. In addition, the soybean oil mixture at this stage will change color significantly as the hydrogenation reaction proceeds. For example, after the reaction is completed, After being made, the soybean oil mixture will appear transparent light yellow. The above phenomenon can be used to judge the degree of hydrogenation heating. Therefore, the present application constructs a state analysis unit and calculates the hydrogenation stability characterization parameters, taking into account the bubble coverage area and the brightness of the mixture into the calculation. The phenomenon presented by the change of the above parameters is obvious. The data collected in this way is highly representative and can more explicitly characterize the stability of the hydrogenation heating process. The hydrogenation stability characterization parameters provide data support for the subsequent classification of the stability tendency category of hydrogenation heating, so as to facilitate the subsequent adaptive control of the mixing mechanism to heat the mixture, thereby improving the hydrogenation heating effect and ensuring the stability and quality of the soybean wax.

[0039] In particular, the present invention divides the stable tendency categories of hydrogenation heating, and adaptively controls the relevant parameters of the mixing mechanism when heating the mixture. In actual situations, if the hydrogenation heating is in the weakly stable tendency category, the subsequent hydrogenation reaction is prone to abnormalities, resulting in a sudden change in the reaction rate, affecting the effect of the hydrogenation heating process. Therefore, the above phenomenon is characterized by abnormal changes in the air pressure in the stirring chamber, and timely monitoring and adjustment of relevant parameters are carried out to ensure the stability of the heating process. Therefore, the present application specifically controls the relevant parameters of the mixing mechanism when heating the mixture, and effectively deals with situations that do not meet the standards, for example, a sudden change in the air pressure in the stirring chamber leads to a sudden change in the reaction rate, and adaptive adjustments are made, thereby improving the hydrogenation heating effect and ensuring the stability and quality of the soybean wax.

[0064] Specifically, the present invention constructs a state analysis unit, extracts hydrogenation characterization features based on the surface image of the mixture, and calculates hydrogenation stability characterization parameters in combination with stirring pressure. During the hydrogenation heating stage, bubbles are generated due to the influence of hydrogenation reaction and stirring. More bubbles increase the contact area between the mixture and the air, accelerating the oxidation process of the mixture. In particular, the above problems will be aggravated when the hydrogenation reaction is in a violent reaction stage. Moreover, if the heat temperature is too high or the heating is uneven, it may cause local overheating of the oil, which will also form bubbles and affect the uniformity of the mixture. In addition, the soybean oil mixture at this stage will change color significantly as the hydrogenation reaction proceeds. For example, the reaction After completion, the soybean oil mixture will appear transparent light yellow. The above phenomenon can be used to determine the degree of hydrogenation heating. Therefore, the present application constructs a state analysis unit and calculates the hydrogenation stability characterization parameters, taking into account the bubble coverage area and the brightness of the mixture into the calculation. The phenomenon presented by the change of the above parameters is obvious. The data collected in this way is highly representative and can more explicitly characterize the stability of the hydrogenation heating process. The hydrogenation stability characterization parameters provide data support for the subsequent classification of the stability tendency category of hydrogenation heating, so as to facilitate the subsequent adaptive control of the mixing mechanism to heat the mixture, thereby improving the hydrogenation heating effect and ensuring the stability and quality of the soybean wax.

[0070] If the stability tendency category of the hydrogenation heating is a strong stability tendency category, the heating unit is controlled to maintain the initial heating rate.

[0071] Specifically, the present invention divides the stable tendency categories of hydrogenation heating, and adaptively controls the relevant parameters of the mixing mechanism when heating the mixture. In actual situations, if the hydrogenation heating is in the weakly stable tendency category, the subsequent hydrogenation reaction is prone to abnormalities, resulting in a sudden change in the reaction rate, affecting the effect of the hydrogenation heating process. Therefore, the above phenomenon is characterized by abnormal changes in the air pressure in the stirring chamber, and timely monitoring and adjustment of relevant parameters are carried out to ensure the stability of the heating process.
