Description

Technical Field

[0001] This invention relates to the field of food processing control technology, and more specifically, to a method for controlling the pulping process in the production process of candied white fungus and lotus root cake. Background Technology

[0002] In the core processing steps of candied white fungus and lotus root cakes, the effect of beating the white fungus and lotus seeds after stewing them in rice wine directly determines the smoothness, viscosity, and nutrient release efficiency of the paste, which in turn affects the processing stability of subsequent mixing, pressing, and frying, ultimately affecting the taste and quality of the finished product.

[0003] In existing technologies, pulping control often employs a crude operation with fixed rotation speed and duration, or relies solely on passive monitoring using a single rotation speed sensor, which has the following key drawbacks:

[0004] 1. The influence of fluctuations in raw material characteristics was not considered. The batch differences in the moisture content of white fungus, the maturity of lotus seeds, and the amount of rice wine added resulted in the slurry being either too coarse or overly pulverized under fixed parameters, leading to poor consistency in taste.

[0005] 2. Lacking a multi-dimensional feedback and dynamic correction mechanism, relying solely on rotation speed to judge fineness makes it impossible to accurately perceive the actual particle state of the slurry, which can easily lead to misjudgments such as "rotation speed meets the standard but slurry is unqualified".

[0006] 3. The control logic lacks mathematical model support, and the adjustment methods are mostly one-time abrupt changes, which can easily lead to slurry viscosity imbalance and affect the processing adaptability of subsequent processes.

[0007] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0008] To address the problems in related technologies, this invention proposes a pulping and processing control method based on the production process of candied white fungus and lotus root cake, in order to overcome the aforementioned technical problems existing in the existing related technologies.

[0009] The technical solution of this invention is implemented as follows:

[0010] A method for controlling the pulping process in the production of candied white fungus and lotus root cakes includes the following steps:

[0011] Step S1: After starting the pulping equipment, real-time data is collected in advance through dual sensors, including the real-time acquisition of the actual rotation speed of the pulping equipment through a speed sensor. And the actual particle diameter of the slurry can be detected in real time using a laser particle size sensor. Where t is the pulping running time;

[0012] Step S2 involves dynamically correcting the rotational speed based on the collected real-time data. This dynamic speed correction includes rotational speed feedback adjustment, granularity feedback adjustment, and shutdown determination. The steps include:

[0013] Step S201: Perform speed feedback adjustment to preset the initial speed. The target value is set, and the deviation between the actual speed and the target value is corrected by the PID control algorithm to ensure that the speed is stable within the allowable range.

[0014] Step S202: Calibrate the target threshold for slurry particle size. Based on the stable rotation speed, dynamic control is carried out under two working conditions to ensure that the fineness of the slurry meets the standard and there is no risk of over-crushing.

[0015] Step S203: The shutdown determination is based on the condition that the actual particle diameter of the slurry meets the qualified threshold and the state continues for a preset time, triggering the slurry completion command.

[0016] Furthermore, the speed feedback adjustment includes the following steps:

[0017] The deviation of the calibrated speed is expressed as: ;

[0018] in, This is the initial value of the pulping speed; This indicates that the actual rotational speed is lower than the target value. This indicates that the actual rotational speed is higher than the target value.

[0019] The speed deviation rate is calculated and expressed as:

[0020] ;

[0021] Among them, the preset speed deviation allowable range threshold If the speed exceeds this range, speed correction will be initiated.

[0022] The PID control output is obtained and represented as:

[0023] ;

[0024] in, It is a proportional element used to quickly respond to speed deviations, and directly outputs the adjustment amount according to the magnitude of the deviation to achieve rapid speed correction; This is an integral term used to eliminate static deviations. When there is a continuous small deviation in speed, it is gradually corrected through integral accumulation to ensure that the speed is stable at the target value. This is the differential element, used to predict the trend of speed change, suppress large fluctuations in speed in advance, and avoid over-adjustment;

[0025] Obtain the corrected rotational speed, and satisfy the following conditions: , is represented as:

[0026]

[0027] in, This is the maximum speed threshold.

[0028] Furthermore, the dynamic control is performed under two operating conditions, including:

[0029] like and This means that the pulp fineness and rotation speed are both stable and meet the standards, and the current pulping parameters are maintained unchanged. .

[0030] Furthermore, it also includes: if but This means that if the rotational speed is deemed sufficient but the slurry is too coarse, a step-by-step speed-up strategy is triggered, as shown below:

[0031]

[0032] in, To increase the speed, For the current stable speed, The acceleration is achieved through a stepped gradient, maintaining a constant speed after each acceleration stage. Then, it is detected by a particle size sensor. until .

[0033] Furthermore, the triggering of the pulping completion command includes: when the actual particle diameter of the pulp meets the following conditions... And the duration of this state When the pulping process is completed, it indicates a stable state, which triggers a shutdown decision to ensure that the pulp quality is stable before ending the pulping process.

[0034] The beneficial effects of this invention are:

[0035] This invention provides a scientific and intelligent control solution for the pulping process of candied lotus root cakes by constructing a closed-loop precision control system that integrates multi-sensor data acquisition and PID control algorithms. It achieves dynamic sensing and precise control of the pulp's fineness, effectively avoiding the problems of coarse or overly pulverized pulp caused by fluctuations in raw material characteristics under traditional fixed-parameter pulping modes, thus ensuring the consistency and stability of the taste across different batches. The innovative stepped acceleration strategy, through gradual parameter adjustment, avoids the damage to the pulp's viscosity caused by sudden changes in rotation speed, ensuring that the pulp achieves the ideal fineness while also taking into account the subsequent mixing, pressing, and frying processes. The adaptability of the control mechanism provides crucial support for the stability of the entire production process. Through real-time data feedback and dynamic algorithm correction, the closed-loop control system can automatically adapt to fluctuations in variables such as raw material moisture content, maturity, and the amount of rice wine added. It also compensates for speed deviations during equipment operation, significantly reducing the need for manual intervention, minimizing human error, and improving the automation level and ease of operation of the production process. All control parameters have clear physical meaning and flexible adjustment space, allowing for personalized adaptation based on different finished product taste requirements and raw material characteristics. This provides a valuable practical paradigm for the application of intelligent control technology in the food processing industry. Attached Figure Description

[0041] Step S1: After starting the pulping equipment, real-time data is collected in advance through dual sensors, including the real-time acquisition of the actual rotation speed of the pulping equipment through a speed sensor. And the actual particle diameter of the slurry can be detected in real time using a laser particle size sensor. Where t is the pulping running time;

[0042] Step S2, based on the collected real-time data, performs dynamic correction of the rotational speed, including the following steps:

[0043] Step S201: Perform speed feedback adjustment to preset the initial speed. To achieve the target value, a PID control algorithm is used to correct the deviation between the actual speed and the target value, ensuring that the speed remains stable within the allowable range. This includes the following steps:

[0044] The deviation of the calibrated speed is expressed as: ;

[0045] in, The initial operating speed is set based on the basic characteristics of the raw materials. This indicates that the actual rotational speed is lower than the target value. This indicates that the actual rotational speed is higher than the target value.

[0046] In this technical solution, the initial value of the pulping speed... Based on the basic test data of the moisture content of white fungus, the maturity of lotus seeds and the amount of rice wine added, the value range is set from 1500r / min to 3000r / min.

[0047] The speed deviation rate is calculated and expressed as:

[0048] ;

[0049] Among them, the preset speed deviation allowable range threshold The value is set to 3%. If the value exceeds this range, speed correction will be initiated. When this happens, PID control is initiated;

[0057] Step S202: Perform particle size feedback adjustment, i.e., calibrate the target threshold for slurry particle size. Based on the stable rotation speed, dynamic control is implemented under two operating conditions to ensure that the slurry fineness meets the standard without the risk of over-crushing. The value is [value to be filled in]. ,in, This is the over-grinding warning threshold. When the diameter of the slurry particles is below this value, it is considered over-grinding. This refers to the maximum particle diameter of a qualified slurry; specifically as follows:

[0059] This means that the pulp fineness and rotation speed are both stable and meet the standards, and the current pulping parameters are maintained unchanged. .

[0060] Among them, working condition two is represented as: but ;

[0061] If the rotational speed is deemed sufficient but the slurry is too coarse, a step-by-step speed-up strategy is triggered, as shown below:

[0062]

[0063] in, To increase the speed, For the current stable speed, The acceleration is achieved through a stepped gradient, maintaining a constant speed after each acceleration stage. Then, it is detected by a particle size sensor. until .

[0064] Specifically, a stepped acceleration gradient The value range is 50 r / min-150 r / min, and the duration of maintenance after each speed increase is... The value range is 30s-60s; among which, the qualified threshold for slurry particle size is... The value range is 50μm-100μm, and the excessive pulverization warning threshold is... The value range is 20μm-30μm.

[0065] In step S203, when determining whether to stop the machine, that is, when the actual particle diameter of the slurry meets the requirements... And the duration of this state When the pulping process is completed, it indicates a stable state, which triggers a shutdown decision to ensure that the pulp quality is stable before ending the pulping process.

[0066] Among them, downtime stabilization time This indicates the duration for which the particle size of the slurry needs to remain stable after reaching the standard.

[0067] Specifically, downtime stabilization time The value ranges from 60s to 120s and can be adjusted to suit individual taste preferences.

[0068] In summary, by employing the above-described technical solution of the present invention, the following effects can be achieved:
