Description

Technical Field

[0001] The invention relates to the technical field of seabuckthorn oil extraction, in particular to an integrated seabuckthorn oil extraction and synthesis device. Background Art

[0002] Seabuckthorn oil is extracted from seabuckthorn fruit. Seabuckthorn oil is a nutritious plant oil that can be used to prepare cosmetics, medicines, foods and industrial products. There are many ways to extract seabuckthorn oil. There are three common extraction methods: cold pressing method: This is a traditional seabuckthorn oil extraction method. The oil in the seabuckthorn fruit is mechanically cold pressed out. This method does not require the use of chemical extractants and can retain the natural nutrients of the oil, but the yield is low; extractant extraction method: The oil in the seabuckthorn fruit is dissolved using a chemical extractant (such as ether, acetone or ethanol), and then the seabuckthorn oil is obtained by evaporating the extractant. This method has a high yield, but it is necessary to pay attention to removing the residual chemical extractant; supercritical fluid extraction method: The seabuckthorn fruit is extracted using a supercritical fluid (such as carbon dioxide). This method can be carried out at a lower temperature to reduce the thermal sensitivity of the oil, and no extractant residue is left. For synthetic cosmetics using seabuckthorn oil, the extractant extraction method is generally used, which has a higher yield, and compared with the supercritical fluid extraction method, its cost is lower and the extraction conditions are lower.

[0057] Example 3

[0058] This embodiment adds a control unit on the basis of the above embodiment; the device also includes a control unit (the control unit is not shown in the figure), which is arranged on the outer wall of the extraction tank 1. The control unit is used to control the heating extraction time of the extraction tank 1. The control unit includes:

The real-time extraction raw material coefficient, type of extractant and heating temperature are collected, and the heating extraction time is predicted based on the trained machine learning model.

[0061] The controller controls the heating extraction time of the extraction tank 1 based on the predicted heating extraction time.

[0062] The parameters that affect the extraction raw material coefficient include the particle size of seabuckthorn seed powder and the ratio of seabuckthorn seed powder to extractant;

[0063] The expression of the extraction raw material coefficient is:

[0064]

[0065] Where CUxs is the extraction raw material coefficient, XJf is the particle size of seabuckthorn seed powder, is the ratio of seabuckthorn seed powder to extractant, and is the weight factor, and Both are greater than 0.

[0066] It should be noted that the larger the extraction raw material coefficient, the slower the extraction efficiency and the longer the heating extraction time, and vice versa. Secondly, the larger the particle size of the sea buckthorn seed powder, the slower the extraction efficiency, and vice versa.

[0069] Convert the collected historical extraction training data into a corresponding set of feature vectors;

[0070] Each group of feature vectors is used as the input of the machine learning model. The machine learning model takes the heating extraction time corresponding to each group of heating temperature, extraction raw material coefficient and type of extractant as the output, and takes the heating extraction time actually corresponding to each group of heating temperature, extraction raw material coefficient and type of extractant as the prediction target. Minimizing the loss function value of the machine learning model is used as the training target. The training is stopped when the loss function value of the machine learning model is less than or equal to the preset target loss value.

[0071] The machine learning model is one of the models such as SVM regression, random forest regression or neural network regression.

[0072] The loss function value of the machine learning model is the mean square error;

[0073] Mean square error is one of the commonly used loss functions. Minimization is used to train the model so that the machine learning model can better fit the data, thereby improving the performance and accuracy of the model;

[0074] In the loss function, MSE is the loss function value of the machine learning model, n is the feature vector group number; m is the number of feature vector groups; y nis the heating extraction time predicted by the nth group of feature vectors, is the heating extraction time actually corresponding to the nth group of characteristic vectors.

[0075] Specifically, a control unit is provided, which trains a machine learning model for predicting the heating extraction time by collecting historical extraction training data of sea buckthorn, namely, heating temperature, extraction raw material coefficient, type of extractant and heating extraction time, and then collects real-time extraction raw material coefficient, type of extractant and heating temperature, and predicts the heating extraction time based on the trained machine learning model, and then automatically controls the heating extraction time of the extraction tank 1 based on the predicted heating extraction time, thereby realizing intelligent control, and improving the extraction efficiency compared with the traditional manually set extraction time.
