Description

Technical Field

[0001] This invention relates to the field of seed husk separation technology, and more specifically, to a method for separating the seed husk of Torreya grandis. Background Technology

[0002] Torreya grandis is a precious nut whose fruit consists of a hard outer shell and an inner kernel. In the traditional processing of Torreya grandis, separating the seed coat is an important and tedious step.

[0003] In the process of separating the kernels from the husks of Torreya nuts, pre-treatment of the nuts, such as washing and drying, is usually required to ensure the smooth progress of subsequent separation steps. Then, specific mechanical devices or hand tools are used to apply appropriate force to the Torreya nuts, separating the outer shell from the kernel. The key to this process is controlling the force and method of separation to avoid damaging the kernel while ensuring effective removal of the husks.

[0004] However, existing methods for separating seed husks have many shortcomings. For example, traditional mechanical devices often struggle to precisely control the separation force, easily leading to kernel damage and affecting product quality and value. While manual separation with tools can reduce kernel damage to some extent, it is inefficient and cannot meet the needs of large-scale production.

[0005] Therefore, it is necessary to design a method for separating the seed coat of Torreya grandis to solve the problems existing in the current technology. Summary of the Invention

[0006] In view of this, the present invention proposes a method for separating the seed coat of Torreya grandis, aiming to develop an efficient and non-destructive method for separating the seed coat of Torreya grandis.

[0007] This invention proposes a method for separating the seed coat of Torreya grandis, comprising:

[0008] The torreya nuts to be screened are identified, and the torreya nuts to be screened are grouped according to their length range to obtain torreya nut groups to be separated.

[0009] The physical property data of the Torreya grandis group to be separated are collected and analyzed. Based on the analysis results, the initial crushing force of the Torreya grandis group to be separated is determined.

[0010] A shell-breaking device is used to perform a crushing and separation test on the group of Torreya grandis to be separated at the initial crushing force. Test data after the crushing and separation test is collected, and it is determined whether the initial crushing force should be adjusted based on the test data.

[0011] If so, the actual operating parameters of the shell-breaking device are collected, and the initial crushing force is adjusted according to the actual operating parameters to obtain the final crushing force.

[0012] Furthermore, when grouping the Torreya nuts to be screened according to length intervals to obtain Torreya nut groups to be separated, the process includes:

[0013] Define a first length interval, a second length interval, and a third length interval;

[0014] The Torreya nuts to be screened whose length is within the first length range are divided into the first group of Torreya nuts to be separated;

[0015] The Torreya grandis to be screened whose length is within the second length range are divided into the second group of Torreya grandis to be separated;

[0016] The Torreya nuts to be screened that are within the third length range are divided into the third group of Torreya nuts to be separated.

[0017] Furthermore, when analyzing the physical property data and determining the initial crushing force of the Torreya grandis group to be separated based on the analysis results, the following steps are included:

[0018] The physical property data are analyzed to obtain the shell thickness characteristic value, shell hardness characteristic value, moisture content characteristic value, and shell kernel binding tightness characteristic value of the Torreya grandis group to be separated;

[0019] The conventional crushing force of the Torreya grandis group to be separated is determined based on the shell thickness characteristic value.

[0020] Determine whether to optimize the conventional crushing force based on the shell hardness characteristic value;

[0021] If so, an optimized feature group is constructed based on the moisture content characteristic value and the shell-kernel binding tightness characteristic value. An optimization coefficient for the conventional crushing force is determined based on the optimized feature group, and the product of the optimization coefficient and the conventional crushing force is used as the initial crushing force.

[0022] Furthermore, when determining the conventional crushing force of the Torreya grandis group to be separated based on the shell thickness characteristic value, the following steps are included:

[0023] The shell thickness characteristic value is compared with the first shell thickness characteristic value and the second shell thickness characteristic value, and the conventional crushing force of the Torreya grandis group to be separated is determined according to the comparison result; wherein, the first shell thickness characteristic value is smaller than the second shell thickness characteristic value.

[0024] When the shell thickness characteristic value is less than or equal to the first shell thickness characteristic value, the conventional crushing force of the Torreya grandis group to be separated is determined to be the first crushing force.

[0025] When the shell thickness characteristic value is greater than the first shell thickness characteristic value and less than or equal to the second shell thickness characteristic value, the conventional crushing force of the group of Torreya grandis to be separated is determined to be the second crushing force, which is greater than the first crushing force.

[0026] When the shell thickness characteristic value is greater than the second shell thickness characteristic value, the conventional crushing force of the Torreya grandis group to be separated is determined to be the third crushing force, which is greater than the second crushing force.

[0027] Furthermore, when determining whether to optimize the conventional crushing force based on the shell hardness characteristic value, the following steps are included:

[0028] Obtain the shell hardness standard value corresponding to the shell hardness characteristic value, and calculate the ratio of the shell hardness characteristic value to the shell hardness standard value, which is denoted as the shell hardness ratio.

[0029] The shell hardness ratio is compared with the shell hardness ratio threshold, and the comparison result is used to determine whether the conventional crushing force should be optimized.

[0030] When the shell hardness ratio is within the threshold range of the shell hardness ratio, it is determined that the conventional crushing force will not be optimized.

[0031] When the shell hardness ratio is outside the threshold range of the shell hardness ratio, it is determined that the conventional crushing force should be optimized.

[0032] Furthermore, when determining the optimization coefficient of the conventional crushing force based on the optimized feature set, it includes:

[0033] The optimized feature group is compared with the historical optimized group, and the optimization coefficient of the conventional crushing force is determined based on the comparison result.

[0034] When there is a historical optimization feature group in the historical optimization group that is the same as the optimization feature group, the historical optimization coefficient corresponding to the historical optimization feature group is used as the optimization coefficient;

[0035] When there is no historical optimization feature group in the historical optimization group that is the same as the optimization feature group, the similarity between the historical optimization group and each historical optimization feature group is calculated, and the highest similarity is obtained. The optimization coefficient is determined based on the highest similarity.

[0036] Furthermore, when determining the optimization coefficient based on the highest similarity, the process includes:

[0037] The highest similarity is compared with the similarity threshold, and the optimization coefficient is determined based on the comparison result;

[0038] When the highest similarity is greater than or equal to the similarity threshold, the historical optimization coefficient corresponding to the highest similarity is used as the optimization coefficient;

[0039] When the highest similarity is less than the similarity threshold, the difference between the highest similarity and the similarity threshold is calculated and recorded as the similarity difference.

[0040] The similarity difference is compared with the first similarity difference and the second similarity difference, and the optimization coefficient is determined based on the comparison result; wherein the first similarity difference is less than the second similarity difference;

[0041] When the similarity difference is less than or equal to the first similarity difference, the optimization coefficient is determined to be the first optimization coefficient;

[0042] When the similarity difference is greater than the first similarity difference and less than or equal to the second similarity difference, the optimization coefficient is determined to be the second optimization coefficient, and the second optimization coefficient is less than the first optimization coefficient;

[0043] When the similarity difference is greater than the second similarity difference, the optimization coefficient is determined to be the third optimization coefficient, and the third optimization coefficient is less than the second optimization coefficient.

[0044] Furthermore, when determining whether to adjust the initial crushing force based on the test data, the following steps are included:

[0045] The test data is analyzed to obtain the whole kernel rate of the Torreya grandis group to be separated;

[0046] The kernel wholeness rate is compared with a preset kernel wholeness rate threshold, and the initial crushing force is adjusted based on the comparison result.

[0047] When the whole kernel ratio is greater than or equal to the preset whole kernel ratio threshold, it is determined that the initial crushing force will not be adjusted.

[0048] When the whole kernel ratio is less than the preset whole kernel ratio threshold, it is determined that the initial crushing force should be adjusted.

[0049] Furthermore, when adjusting the initial crushing force based on the actual operating parameters to obtain the final crushing force, the following steps are included:

[0050] The actual operating parameters are analyzed to obtain the actual crushing frequency and actual crushing time of the shell-breaking device;

[0051] The separation influencing factor of the Torreya grandis group to be separated is determined based on the actual crushing frequency and actual crushing time.

[0052] The adjustment coefficient of the initial crushing force is determined based on the separation influence factor, and the product of the adjustment coefficient and the initial crushing force is taken as the final crushing force.

[0053] Furthermore, when determining the adjustment coefficient for the initial crushing force based on the separation influencing factor, the following steps are included:

[0054] The separation influence factor is compared with the first separation influence factor and the second separation influence factor, and the adjustment coefficient of the initial crushing force is determined according to the comparison result; wherein, the first separation influence factor is smaller than the second separation influence factor;

[0055] When the separation influence factor is less than or equal to the first separation influence factor, the adjustment coefficient of the initial crushing force is determined to be the first adjustment coefficient;

[0056] When the separation influence factor is greater than the first separation influence factor and less than or equal to the second separation influence factor, the adjustment coefficient of the initial crushing force is determined to be the second adjustment coefficient, and the second adjustment coefficient is greater than the first adjustment coefficient.

[0057] When the separation influence factor is greater than the second separation influence factor, the adjustment coefficient of the initial crushing force is determined to be the third adjustment coefficient, and the third adjustment coefficient is greater than the second adjustment coefficient.

[0058] Compared with existing technologies, the beneficial effects of this invention are as follows: The method for separating the seed coat of Torreya grandis provided by this invention can precisely control the separation of Torreya grandis fruits of different length ranges and with different physical characteristics, achieving efficient and non-destructive separation of the seed coat. By grouping the Torreya grandis fruits by length, it can be ensured that each group of Torreya grandis fruits has similar physical characteristics, thereby improving the accuracy and efficiency of subsequent separation steps. At the same time, by collecting and analyzing the physical characteristic data of Torreya grandis fruits, such as shell thickness, shell hardness, moisture content, and shell-kernel bonding tightness, the initial crushing force of each group of Torreya grandis fruits can be further precisely determined, avoiding damage to the kernels during separation. In addition, this embodiment also provides a method for adjusting the initial crushing force to ensure that the best separation effect can be achieved in actual operation. This method not only improves the efficiency and accuracy of Torreya grandis seed coat separation but also reduces the kernel breakage rate, thereby improving the quality and value of Torreya grandis products.

[0061] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0062] See Figure 1 As shown in some embodiments of this application, this embodiment provides a method for separating the seed coat of Torreya grandis, including the following steps:

[0063] S100: Determine the Torreya grandis to be screened, and group the Torreya grandis to be screened according to the length range to obtain Torreya grandis groups to be separated;

[0064] S200: Collect the physical property data of the Torreya grandis group to be separated, analyze the physical property data, and determine the initial crushing force of the Torreya grandis group to be separated based on the analysis results;

[0065] S300: The shell-breaking device is used to perform a crushing and separation test on the group of Torreya grandis to be separated with the initial crushing force, and the test data after the crushing and separation test is collected. Based on the test data, it is determined whether the initial crushing force should be adjusted.

[0066] S400: If so, the actual operating parameters of the shell-breaking device are collected, and the initial crushing force is adjusted according to the actual operating parameters to obtain the final crushing force.

[0067] In this embodiment, the initial crushing force refers to the preset crushing force value before the shell-breaking equipment starts the crushing and separation operation. This value is determined based on the physical characteristic data of the torreya nuts to be separated, aiming to ensure the crushing and separation effect while minimizing damage to the kernels.

[0068] It is understood that the seed-husk separation method for Torreya grandis provided in this embodiment can precisely control the separation of Torreya grandis fruits of different length ranges and with different physical characteristics, achieving efficient and non-destructive separation of the seed-husk. By grouping the Torreya grandis fruits by length, it can be ensured that each group of Torreya grandis fruits has similar physical characteristics, thereby improving the accuracy and efficiency of subsequent separation steps. At the same time, by collecting and analyzing the physical characteristic data of Torreya grandis fruits, such as shell thickness, shell hardness, moisture content, and shell-kernel bonding tightness, the initial crushing force of each group of Torreya grandis fruits can be further precisely determined, avoiding damage to the kernels during separation. In addition, this embodiment also provides a method for adjusting the initial crushing force to ensure that the best separation effect can be achieved in actual operation. This method not only improves the efficiency and accuracy of Torreya grandis seed-husk separation but also reduces the kernel breakage rate, thereby improving the quality and value of Torreya grandis products.

[0069] Specifically, when grouping the Torreya nuts to be screened according to length intervals to obtain Torreya nut groups to be separated, the process includes:

[0070] Define a first length interval, a second length interval, and a third length interval;

[0071] The Torreya nuts to be screened whose length is within the first length range are divided into the first group of Torreya nuts to be separated;

[0072] The Torreya grandis to be screened whose length is within the second length range are divided into the second group of Torreya grandis to be separated;

[0073] The Torreya nuts to be screened that are within the third length range are divided into the third group of Torreya nuts to be separated.

[0074] Understandably, by setting different length intervals, the nuts of Torreya grandis can be classified more precisely, ensuring that each group of nuts exhibits more consistent physical characteristics in the subsequent crushing and separation steps. This grouping method helps improve the uniformity and consistency of husk separation, further enhancing separation efficiency and product quality. In practice, the first, second, and third length intervals can be flexibly set according to the actual size distribution of the Torreya grandis nuts to ensure the rationality and effectiveness of the grouping process.

[0075] Specifically, when analyzing the physical property data and determining the initial crushing force of the Torreya grandis group to be separated based on the analysis results, the following steps are included:

[0076] The physical property data are analyzed to obtain the shell thickness characteristic value, shell hardness characteristic value, moisture content characteristic value, and shell kernel binding tightness characteristic value of the Torreya grandis group to be separated;

[0077] The conventional crushing force of the Torreya grandis group to be separated is determined based on the shell thickness characteristic value.

[0078] Determine whether to optimize the conventional crushing force based on the shell hardness characteristic value;

[0079] If so, an optimized feature group is constructed based on the moisture content characteristic value and the shell-kernel binding tightness characteristic value. An optimization coefficient for the conventional crushing force is determined based on the optimized feature group, and the product of the optimization coefficient and the conventional crushing force is used as the initial crushing force.

[0080] Understandably, in-depth analysis of physical property data allows for a more accurate understanding of the characteristics of Torreya grandis fruits, thus providing more precise control parameters for their crushing and separation. Shell thickness characteristic values ​​reflect the thickness of the Torreya grandis fruit's outer shell and are crucial for determining the standard crushing force. Shell hardness characteristic values ​​reveal the hardness of the Torreya grandis fruit's outer shell, helping to determine whether the standard crushing force needs optimization. When the shell hardness is high, it may be necessary to increase the crushing force to ensure separation; conversely, when the shell hardness is low, the crushing force can be appropriately reduced to avoid damaging the kernel. Moisture content characteristic values ​​and shell-kernel bonding tightness characteristic values ​​further provide clues for optimizing the crushing force. Torreya grandis fruits with high moisture content may require increased humidity control during crushing to prevent excessive fragmentation during shell-kernel separation. Torreya grandis fruits with high shell-kernel bonding tightness require more precise crushing force control to ensure complete separation of the shell and kernel.

[0081] Specifically, determining the conventional crushing force of the Torreya grandis group to be separated based on the shell thickness characteristic value includes:

[0082] The shell thickness characteristic value is compared with the first shell thickness characteristic value and the second shell thickness characteristic value, and the conventional crushing force of the Torreya grandis group to be separated is determined according to the comparison result; wherein, the first shell thickness characteristic value is smaller than the second shell thickness characteristic value.

[0083] When the shell thickness characteristic value is less than or equal to the first shell thickness characteristic value, the conventional crushing force of the Torreya grandis group to be separated is determined to be the first crushing force.

[0084] When the shell thickness characteristic value is greater than the first shell thickness characteristic value and less than or equal to the second shell thickness characteristic value, the conventional crushing force of the group of Torreya grandis to be separated is determined to be the second crushing force, which is greater than the first crushing force.

[0085] When the shell thickness characteristic value is greater than the second shell thickness characteristic value, the conventional crushing force of the Torreya grandis group to be separated is determined to be the third crushing force, which is greater than the second crushing force.

[0086] Understandably, by comparing the shell thickness characteristic value with preset first and second shell thickness characteristic values, the standard crushing force for Torreya nuts can be determined more accurately. This comparison method fully considers the diversity of Torreya nut shell thickness, ensuring that Torreya nuts of different thicknesses receive appropriate crushing treatment. When the shell thickness characteristic value is small, meaning the Torreya nut shell is thin, selecting a smaller first crushing force can avoid over-crushing and protect the integrity of the kernel. Conversely, when the shell thickness characteristic value is large, meaning the Torreya nut shell is thick, a larger second or third crushing force is selected to ensure effective separation of the shell and kernel. This method of flexibly adjusting the crushing force based on the shell thickness characteristic value not only improves the efficiency and accuracy of seed coat separation but also further reduces the kernel breakage rate, bringing significant advantages to the processing and production of Torreya nut products.

[0087] Specifically, when determining whether to optimize the conventional crushing force based on the shell hardness characteristic value, the following steps are included:

[0088] Obtain the shell hardness standard value corresponding to the shell hardness characteristic value, and calculate the ratio of the shell hardness characteristic value to the shell hardness standard value, which is denoted as the shell hardness ratio.

[0089] The shell hardness ratio is compared with the shell hardness ratio threshold, and the comparison result is used to determine whether the conventional crushing force should be optimized.

[0090] When the shell hardness ratio is within the threshold range of the shell hardness ratio, it is determined that the conventional crushing force will not be optimized.

[0091] When the shell hardness ratio is outside the threshold range of the shell hardness ratio, it is determined that the conventional crushing force should be optimized.

[0092] Specifically, determining the optimization coefficient of the conventional crushing force based on the optimized feature set includes:

[0093] The optimized feature group is compared with the historical optimized group, and the optimization coefficient of the conventional crushing force is determined based on the comparison result.

[0094] When there is a historical optimization feature group in the historical optimization group that is the same as the optimization feature group, the historical optimization coefficient corresponding to the historical optimization feature group is used as the optimization coefficient;

[0095] When there is no historical optimization feature group in the historical optimization group that is the same as the optimization feature group, the similarity between the historical optimization group and each historical optimization feature group is calculated, and the highest similarity is obtained. The optimization coefficient is determined based on the highest similarity.

[0096] Understandably, the similarity calculation process employs a feature-matching-based optimization coefficient determination method. First, several historical optimization groups are extracted from the historical optimization database. Each historical optimization group contains a moisture content feature value, a kernel-shell binding tightness feature value, and a corresponding optimization coefficient. Then, the optimization feature group of the current Torreya grandis group to be separated is compared one by one with the historical optimization groups. If a completely matching historical optimization feature group is found, its corresponding optimization coefficient is directly adopted. If no completely matching historical optimization feature group is found, the similarity between the current optimization feature group and each historical optimization group is calculated. The similarity calculation can comprehensively consider the differences in moisture content feature values ​​and kernel-shell binding tightness feature values, using methods such as Euclidean distance and cosine similarity for quantification. Finally, the historical optimization group with the highest similarity is selected, and its optimization coefficient is appropriately adjusted, serving as the optimization coefficient for the current Torreya grandis group to be separated.

[0097] Understandably, the similarity calculation method considers the moisture content characteristic value, the kernel-shell binding tightness characteristic value, and the weighting relationship between them, ensuring that the determination of the optimization coefficient is scientifically based and accurate. In this way, more personalized crushing force optimization schemes can be provided for Torreya grandis fruits with different physical properties, further improving the efficiency of seed coat separation and the protection of the kernel. Furthermore, comparing historical optimization groups with optimized feature groups not only fully utilizes past experience data but also helps to achieve intelligent and automated crushing force adjustment, improving the controllability and stability of the entire separation process.

[0098] Specifically, determining the optimization coefficient based on the highest similarity includes:

[0099] The highest similarity is compared with the similarity threshold, and the optimization coefficient is determined based on the comparison result;

[0100] When the highest similarity is greater than or equal to the similarity threshold, the historical optimization coefficient corresponding to the highest similarity is used as the optimization coefficient;

[0101] When the highest similarity is less than the similarity threshold, the difference between the highest similarity and the similarity threshold is calculated and recorded as the similarity difference.

[0102] The similarity difference is compared with the first similarity difference and the second similarity difference, and the optimization coefficient is determined based on the comparison result; wherein the first similarity difference is less than the second similarity difference;

[0103] When the similarity difference is less than or equal to the first similarity difference, the optimization coefficient is determined to be the first optimization coefficient;

[0104] When the similarity difference is greater than the first similarity difference and less than or equal to the second similarity difference, the optimization coefficient is determined to be the second optimization coefficient, and the second optimization coefficient is less than the first optimization coefficient;

[0105] When the similarity difference is greater than the second similarity difference, the optimization coefficient is determined to be the third optimization coefficient, and the third optimization coefficient is less than the second optimization coefficient.

[0106] Understandably, by setting similarity thresholds and first and second similarity differences, the optimization coefficients can be determined more precisely based on the highest similarity. When the highest similarity is high, it indicates that the physical characteristics of the current group of Torreya nuts to be separated are very close to those of a historical optimization group. Therefore, the optimization coefficients corresponding to that historical optimization group can be directly adopted to ensure the accuracy and stability of the crushing force. Conversely, when the highest similarity is low, it indicates that the physical characteristics of the current group of Torreya nuts to be separated differ somewhat from those of the historical optimization group. In this case, the optimization coefficients need to be flexibly adjusted based on the similarity difference. By setting different similarity difference ranges and corresponding optimization coefficients, fine-tuning of the crushing force can be achieved to adapt to Torreya nuts with different physical characteristics, further improving the efficiency of husk separation and the protection of the kernels.

[0107] Specifically, determining whether to adjust the initial crushing force based on the test data includes:

[0108] The test data is analyzed to obtain the whole kernel rate of the Torreya grandis group to be separated;

[0109] The kernel wholeness rate is compared with a preset kernel wholeness rate threshold, and the initial crushing force is adjusted based on the comparison result.

[0110] When the whole kernel ratio is greater than or equal to the preset whole kernel ratio threshold, it is determined that the initial crushing force will not be adjusted.

[0111] When the whole kernel ratio is less than the preset whole kernel ratio threshold, it is determined that the initial crushing force should be adjusted.

[0112] Understandably, the whole kernel rate, as an important indicator of the effectiveness of seed husk separation, directly reflects the integrity of the kernel during the separation process. A high whole kernel rate indicates that the current crushing force is sufficient to meet the separation requirements and causes minimal damage to the kernel, thus requiring no adjustment. Conversely, a low whole kernel rate means that the crushing force needs further optimization to improve the efficiency of seed husk separation and the protection of the kernel.

[0113] Specifically, adjusting the initial crushing force according to the actual operating parameters to obtain the final crushing force includes:

[0114] The actual operating parameters are analyzed to obtain the actual crushing frequency and actual crushing time of the shell-breaking device;

[0115] The separation influencing factor of the Torreya grandis group to be separated is determined based on the actual crushing frequency and actual crushing time.

[0116] The adjustment coefficient of the initial crushing force is determined based on the separation influence factor, and the product of the adjustment coefficient and the initial crushing force is taken as the final crushing force.

[0117] In this embodiment, the separation influence factor is obtained by the following formula:

[0118] SIF = A·f·t;

[0119] Where SIF represents the separation influence factor; A represents the normalization coefficient; f represents the actual crushing frequency; and t represents the actual crushing time.

[0120] Understandably, the calculation of the separation influencing factor comprehensively considers the actual crushing frequency and actual crushing time of the shell-crushing equipment, both of which are directly related to the actual effect of seed husk separation. The actual crushing frequency reflects the number of crushing operations performed by the equipment per unit time, while the actual crushing time reflects the duration of each crushing operation. By reasonably setting these two parameters, it can be ensured that the shell-crushing equipment achieves the expected separation effect during operation without causing unnecessary damage to the kernels. Specifically, the calculation formula for the separation influencing factor fully considers the interaction between crushing frequency and crushing time, as well as their combined impact on the seed husk separation effect. This calculation method ensures that the determination of the adjustment coefficient has a scientific basis, thereby enabling precise adjustment of the initial crushing force.

[0121] Specifically, determining the adjustment coefficient for the initial crushing force based on the separation influencing factor includes:

[0122] The separation influence factor is compared with the first separation influence factor and the second separation influence factor, and the adjustment coefficient of the initial crushing force is determined according to the comparison result; wherein, the first separation influence factor is smaller than the second separation influence factor;

[0123] When the separation influence factor is less than or equal to the first separation influence factor, the adjustment coefficient of the initial crushing force is determined to be the first adjustment coefficient;

[0124] When the separation influence factor is greater than the first separation influence factor and less than or equal to the second separation influence factor, the adjustment coefficient of the initial crushing force is determined to be the second adjustment coefficient, and the second adjustment coefficient is greater than the first adjustment coefficient.

[0125] When the separation influence factor is greater than the second separation influence factor, the adjustment coefficient of the initial crushing force is determined to be the third adjustment coefficient, and the third adjustment coefficient is greater than the second adjustment coefficient.

[0126] Understandably, by comparing the separation influencing factor with the preset first and second separation influencing factors, the adjustment coefficient of the initial crushing force can be determined more accurately. This comparison method fully considers various factors in the actual operation of the shell-crushing equipment, ensuring that the determination of the adjustment coefficient is both scientific and reasonable. When the separation influencing factor is small, i.e., the actual crushing frequency and actual crushing time of the shell-crushing equipment are short, selecting a smaller first adjustment coefficient can avoid over-adjustment and maintain the stability of the initial crushing force. Conversely, when the separation influencing factor is large, i.e., the actual crushing frequency and actual crushing time of the shell-crushing equipment are long, a larger second or third adjustment coefficient is selected to ensure that the crushing force can adapt to the actual separation requirements. This method of flexibly adjusting the crushing force based on the separation influencing factor not only further improves the efficiency and accuracy of seed husk separation but also effectively reduces the kernel breakage rate.
