[0002] In the rice processing industry chain, rice bran oil is a functional oil with high nutritional value, and its extraction efficiency and quality directly affect the added value of the industry. Traditional rice bran oil processing mainly relies on physical pressing or solvent extraction. Although the physical pressing method can retain some nutrients, the oil yield is low, and high temperature can easily cause oil oxidation. Although the solvent extraction method can increase the oil yield, the solvent is easy to leave residues.

[0003] Therefore, the prior art has defects and needs to be improved urgently. Summary of the invention

[0004] Based on the above problems, the purpose of the present invention is to provide a broken rice separation control method and system for rice bran processing, which can reduce the proportion of broken rice by real-time monitoring the amount of broken rice generated and feedback-adjusting the grinding parameters; in addition, by mixing and processing oil bran and broken rice according to a preset ratio, rice bran oil is obtained, thereby increasing the added value of rice bran and broken rice.

[0014] Divide the weight of the oil bran by the weight of the brown rice to obtain the yield of the oil bran;

[0015] If the output rate of the oil bran is greater than or equal to the preset first output rate threshold, the current milling of the brown rice is qualified;

[0016] If the output rate of oil bran is less than a preset first output rate threshold, rice grains with a particle size larger than a preset second particle size threshold are extracted, and the rice grains with a particle size larger than the preset second particle size threshold are subjected to secondary grinding.

[0017] This plan also includes:

[0018] The rice grains smaller than the preset first grain size threshold are defined as broken rice, and the weight value of the broken rice is extracted;

[0020] If the broken rice content is less than or equal to the preset broken rice content threshold, the current broken rice content is normal; if the broken rice content is greater than the preset broken rice content threshold, the preset broken rice content threshold is subtracted from the broken rice content to obtain a first broken rice content difference;

[0021] determining a milling speed adjustment value according to a range within which the first broken rice content difference falls;

[0022] The grinding speed value of the current grinding device is obtained, and the grinding speed adjustment value is subtracted from the grinding speed value of the current grinding device to obtain the revised grinding speed value of the current grinding device.

[0023] This plan also includes:

[0026] The actual grinding pressure value of the current grinding device and the ideal grinding pressure value of the current grinding device are calculated, and the absolute value is taken to obtain the grinding pressure difference;

[0027] If the grinding pressure difference is greater than or equal to the preset grinding pressure difference threshold, the actual grinding pressure value of the current grinding device is optimized and replaced according to the ideal grinding pressure value;

[0028] If the grinding pressure difference is less than the preset grinding pressure difference threshold and the broken rice content is less than or equal to the preset broken rice content threshold, the grinding pressure value of the current grinding device does not need to be optimized and replaced;

[0040] The pressure increase value of the vacuum pressing and the pressure value of the vacuum pressing are added together to obtain the revised pressure value of the vacuum pressing.

[0041] In this solution, the formula for obtaining the vacuum pressing efficiency value is specifically:

[0042] Where η represents the vacuum pressing efficiency value, n represents the number of vacuum pressing times of the first mixture, P i represents the pressure value of the i-th vacuum pressing, V i represents the absolute value of vacuum during the i-th vacuum pressing, T represents the temperature during pressing, t represents the cumulative time of pressing, H represents the moisture content of the crushed mixture, and a represents the coefficient.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0065] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0066] Figure 1 The present invention shows a flow chart of a broken rice separation control method for rice bran processing.

[0067] like Figure 1 As shown, the present invention discloses a broken rice separation control method for rice bran processing, comprising:

[0068] S101, based on a preset feeding port, conveying the rice to a preset hulling device to obtain bran and brown rice, and obtaining a weight value of the brown rice;

[0070] S103, extracting rice grains smaller than a preset first particle size threshold;

[0071] S104, mixing rice grains smaller than a preset first particle size threshold and oil bran according to a preset ratio to obtain a first mixture;

[0072] S105, sending the first mixture to a preset pressing device to obtain rice bran oil.

[0073] According to an embodiment of the present invention, rice is husked to separate whole bran and brown rice, and the brown rice is then milled to separate rice grains of different sizes through a preset grid; oily bran and whole bran are the main products derived from rice bran.

[0074] According to an embodiment of the present invention, after obtaining the oil bran and rice grains, the method further comprises:

[0075] Get the weight value of the bran and the total weight value of the rice grains;

[0076] The rice grains are screened and divided according to a preset particle size range to obtain rice grains in different particle size ranges and weight values ​​of the rice grains in the corresponding particle size ranges;

[0077] Divide the weight of the oil bran by the weight of the brown rice to obtain the yield of the oil bran;

[0078] If the output rate of the oil bran is greater than or equal to the preset first output rate threshold, the current milling of the brown rice is qualified;

[0079] If the output rate of oil bran is less than a preset first output rate threshold, rice grains with a particle size larger than a preset second particle size threshold are extracted, and the rice grains with a particle size larger than the preset second particle size threshold are subjected to secondary grinding.

[0080] It should be noted that the preset second particle size range threshold is greater than the preset first particle size range, and the preset particle size range is divided into at least three intervals, a particle size range less than the preset first particle size threshold range, a particle size range greater than or equal to the preset first particle size threshold and less than or equal to the preset second particle size threshold, and a particle size range greater than the preset second particle size threshold; when the cumulative output rate of oil bran after the second grinding is still less than the preset first output rate threshold, an oil bran extraction warning message is generated, indicating that there is a fault in the extraction of oil bran by the current grinding equipment, and the cumulative output rate of oil bran is the sum of the output rate of oil bran after the first grinding and the output rate of oil bran after the second grinding.

[0081] According to an embodiment of the present invention, it also includes:

[0082] The rice grains smaller than the preset first grain size threshold are defined as broken rice, and the weight value of the broken rice is extracted;

[0083] Divide the weight of broken rice by the total weight of rice grains to obtain the broken rice content;

[0084] If the broken rice content is less than or equal to the preset broken rice content threshold, the current broken rice content is normal; if the broken rice content is greater than the preset broken rice content threshold, the preset broken rice content threshold is subtracted from the broken rice content to obtain a first broken rice content difference;

[0085] determining a milling speed adjustment value according to a range within which the first broken rice content difference falls;

[0086] The grinding speed value of the current grinding device is obtained, and the grinding speed adjustment value is subtracted from the grinding speed value of the current grinding device to obtain the revised grinding speed value of the current grinding device.

[0087] It should be noted that the first content difference of broken rice is divided into multiple range intervals according to the size of the numerical value. For example, less than or equal to 3% is an interval, and each increase of 3% is set as a range interval, and each range interval corresponds to a grinding speed adjustment value. If the first content difference of broken rice is 5%, the corresponding first content difference of broken rice falls into the second range interval, and the grinding speed adjustment value set for the second range interval is used.

[0088] According to an embodiment of the present invention, it also includes:

[0089] Obtaining the actual grinding pressure value of the current grinding device;

[0090] The ideal grinding pressure value of the current grinding device is set to P, and its formula is: Where k is a coefficient greater than zero, A 1 is the broken rice content, A 0 is the broken rice content threshold, P 0 is the actual grinding pressure value of the current grinding device;

[0091] The actual grinding pressure value of the current grinding device and the ideal grinding pressure value of the current grinding device are calculated, and the absolute value is taken to obtain the grinding pressure difference;

[0092] If the grinding pressure difference is greater than or equal to the preset grinding pressure difference threshold, the actual grinding pressure value of the current grinding device is optimized and replaced according to the ideal grinding pressure value;

[0093] If the grinding pressure difference is less than the preset grinding pressure difference threshold and the broken rice content is less than or equal to the preset broken rice content threshold, the grinding pressure value of the current grinding device does not need to be optimized and replaced;

[0094] If the grinding pressure difference is less than the preset grinding pressure difference threshold and the broken rice content is greater than the preset broken rice content threshold, the actual grinding pressure value of the current grinding device is optimized and replaced according to the ideal grinding pressure value.

[0095] It should be noted that the broken rice content can be reduced by dynamically adjusting the pressure value of the grinding device.

[0096] According to an embodiment of the present invention, the step of sending the first mixture to a preset pressing device to obtain rice bran oil specifically includes:

[0097] The first mixture is crushed to obtain a crushed mixture;

[0098] The crushed mixture is transported to the interior of the pressing device, and the internal environment of the pressing device is adjusted to a preset vacuum environment based on a preset vacuum extraction device;

[0099] Based on the vacuum environment, the crushed mixture is subjected to the first vacuum pressing to obtain the oil yield and the residue mixture;

[0100] The oil content in the residue mixture is extracted, and if the oil content in the residue mixture is greater than or equal to a preset first oil content threshold, the residue mixture is subjected to a second vacuum pressing.

[0101] It should be noted that, based on the vacuum environment, the first mixture is squeezed multiple times to increase the output rate of bran oil.

[0102] According to an embodiment of the present invention, it also includes:

[0103] Get the vacuum pressing efficiency value;

[0104] Determine whether the vacuum pressing efficiency value is greater than or equal to a preset pressing efficiency threshold value, if so, the current pressing efficiency of the rice bran oil is normal;

[0105] If not, subtract the vacuum pressing efficiency value from the preset pressing efficiency threshold value to obtain the pressing efficiency difference value;

[0106] According to the preset value range that the difference in squeezing efficiency falls into, a squeezing pressure adjustment coefficient is obtained, and based on the squeezing pressure adjustment coefficient multiplied by the pressure value of vacuum squeezing, a pressure increase value of vacuum squeezing is obtained;

[0107] The pressure increase value of the vacuum pressing and the pressure value of the vacuum pressing are added together to obtain the revised pressure value of the vacuum pressing.

[0108] According to an embodiment of the present invention, the formula for obtaining the vacuum pressing efficiency value is specifically:

[0109] Where η represents the vacuum pressing efficiency value, n represents the number of vacuum pressing times of the first mixture, Pi represents the pressure value of the i-th vacuum pressing, V i represents the absolute value of vacuum during the i-th vacuum pressing, T represents the temperature during pressing, t represents the cumulative time of pressing, H represents the moisture content of the crushed mixture, and a represents the coefficient.

[0110] It should be noted that the pressing efficiency difference is divided into multiple preset numerical ranges according to the size of the numerical value. For example, if 2% is a numerical range interval, it can be divided into (0, 2%], (2%, 4%], ..., and each numerical range interval corresponds to a pressing pressure adjustment coefficient, and as the numerical value in the numerical range interval increases, the corresponding pressing pressure adjustment coefficient increases.
