Before batch enzymolysis, an enzymolysis test step is performed on the preset enzymolysis conditions corresponding to the batch enzymolysis. In the enzymolysis test step, the test conditions of the m first enzymolysis tests and the n second enzymolysis tests are the same, and a straw enzymolysis-related material with a smaller weight is selected for the enzymolysis test to avoid waste of materials caused by abnormal enzymolysis and improve the effect of more straw accumulation on enzymolysis efficiency; Based on the m first enzymatic hydrolysis tests, a standard concentration change curve of the key enzymatic hydrolysis component concentration changing with time can be obtained, thereby obtaining the standard concentration change state of the key enzymatic hydrolysis component, and then dividing the standard concentration change curve of the key enzymatic hydrolysis component concentration changing with time into a plurality of sub-curve segments based on the standard concentration change state of the key enzymatic hydrolysis component and numbering the sub-curve segments, thereby selecting the enzymatic hydrolysis time period with a smaller difference change in the ordinate as a sub-curve segment; Then, based on the preset enzymatic hydrolysis conditions, the second enzymatic hydrolysis test is performed n times, and the first parameter detection of the mixed solution is performed several times in the enzymatic hydrolysis time period corresponding to each sub-curve segment, and the standard first parameter of the mixed solution corresponding to the enzymatic hydrolysis time detected each time is obtained, so as to obtain the standard first parameter of the mixed solution of each sub-curve segment based on the second enzymatic hydrolysis test, and the standard first parameter of the mixed solution can be used as a benchmark to evaluate the batch enzymatic hydrolysis process, so as to ensure that the first parameter of the mixed solution can be reliably evaluated during the batch enzymatic hydrolysis process, so as to facilitate timely detection of abnormalities and early warning, so as to adjust the batch enzymatic hydrolysis process and ensure the reliability of the batch enzymatic hydrolysis; Based on the standard concentration change curve of the key enzymatic hydrolysis component concentration over time (reflecting the concentration change state of the key enzymatic hydrolysis component), the total number of detections of the enzymatic hydrolysis time period corresponding to each sub-curve segment is determined to ensure the selection of the number of detections that is adapted to the concentration change state of the key enzymatic hydrolysis component and the reliability of the selection of the number of detections; finally, based on the total number of detections of the first parameter of the mixed solution in each sub-curve segment obtained in the enzymatic hydrolysis test step, the total number of detections of the enzymatic hydrolysis time period corresponding to each sub-curve segment in the batch enzymatic hydrolysis process is determined to ensure reliable detection of the batch enzymatic hydrolysis process; 3. Based on the first and second parameters of the mixed solution in different enzymatic hydrolysis time periods (different sub-curve segments) during the entire straw enzymatic hydrolysis process in the test steps, determine the target power of the stirring motor that matches the first and second parameters of the mixed solution in different enzymatic hydrolysis time periods (different sub-curve segments) and the amount of straw enzymatic hydrolysis-related materials added to the enzymatic hydrolysis box for a single straw enzymatic hydrolysis requirement under preset enzymatic hydrolysis conditions, and ensure that the determined target power of the stirring motor is reliable; Then, during the batch enzymolysis process, during the enzymolysis time corresponding to each sub-curve segment, the stirring motor operates at the target power of the stirring motor during the stirring of the corresponding sub-curve segment, thereby ensuring reliable stirring during the batch enzymolysis process.

[0017] The equivalent target pressure ensures that the mixed liquid has appropriate hydraulic pressure under the stirring action of the stirring blades, ensures the osmotic reaction between the mixed liquid and the straw, and ensures the efficiency of enzymatic hydrolysis; The equivalent target flow rate ensures that the mixed liquid has an appropriate flow rate, avoiding excessive impact on the straw due to excessive flow rate; at the same time, a certain flow rate ensures that the key enzymatic components can be mixed evenly in the mixed liquid, and on the other hand, is more conducive to the penetration reaction between the mixed liquid and the straw.
