Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
Example one
A method of controlling a food processor including an anti-spill electrode, as shown in fig. 1, the method comprising S11-S12:
and S11, detecting the water quality of the slurry according to the state of the slurry foam of the slurry contacting the anti-overflow electrode during the food processing process of the food processing machine.
In the embodiment of the invention, the water quality with high TDS (total dissolved solids) value is tested, the pulp foam is high in the pulping process, and the pulp foam is not easy to eliminate. In view of the situation, the conventional solution is to increase the waiting time of the pulping room, which is usually measured according to a large number of tests and is generally long, so that the total pulping period is long. In addition, in most cases, the pulp foam is difficult to be eliminated in the pulping process only in a single water quality, if the overflow-preventing strategy is assigned to the food processing machine only according to the situation that the pulp foam is difficult to be eliminated in the water quality, the problem that the reaction is too slow and the pulping time is wasted by the assigned overflow-preventing strategy (such as collecting the overflow-preventing signal by an overflow-preventing electrode) if the overflow phenomenon is generated in the process of pulping by using water with other water qualities is caused, and the problem that the final crushing is poor if the pulping is stopped at the moment. Therefore, according to the above contents, the conventional anti-overflow scheme cannot effectively solve the problem of slurry overflow caused by different water qualities.
In the embodiment of the invention, a novel control scheme of the food processor is provided aiming at the problems, the problem of slurry overflow of the soybean milk machine aiming at different water qualities in different regions is solved, the soybean milk making process can be intelligently adjusted according to the characteristics of local water quality, and the self-adaption to the water qualities in different regions is realized.
In the embodiment of the invention, the water quality of the slurry needs to be detected in the food processing process. Due to the influence of water quality characteristics, the slurry overflowing problem caused by different water qualities can enable slurry foam to be in different states when contacting the anti-overflow electrode, and therefore the water quality of the slurry can be detected according to the state of the slurry foam when contacting the anti-overflow electrode.
In the embodiment of the invention, the states of the pulp foam contacting the anti-overflow electrode can comprise the temperature during the anti-overflow and the foam removing time (namely the time length of the foam removing waiting stage) and different water qualities can correspond to different temperatures during the anti-overflow and different foam removing times, so that different water qualities can be determined according to different states in the food processing process. The process of detecting water quality will be described in the following two aspects.
Firstly, according to the foam removing time detection
In the embodiment of the invention, research on water resources in different regions of China discovers that pulp foam is more easily generated in the water with high TDS value than in the water with low TDS value in the pulping process, and the pulp foam is not easy to eliminate. Experiments show that the water quality defoaming time with high TDS value is much longer than that of water with low TDS value by using the same material. Therefore, the scheme of the embodiment can distinguish the difference of the water quality used for pulping according to the difference of the foam removing time by measuring the foam removing time in the waiting process after the anti-overflow stage in the pulping process.
Optionally, the food processing process may include: a foam removing waiting stage; the foam-removing waiting stage is a stage from the moment that the pulp foam contacts the anti-overflow electrode to the moment that the pulp foam is separated from the anti-overflow electrode;
as shown in fig. 2, detecting the water quality of the slurry according to the state of the slurry when the slurry foam of the slurry contacts the anti-overflow electrode may include steps S21-S23:
and S21, detecting the duration of the foam-removing waiting stage.
Optionally, detecting the duration of the foam-removing waiting period may include:
monitoring the state of a preset collision and overflow prevention mark;
when the state of the anti-overflow mark is changed from the first state to the second state, a preset timer is started to start timing until the state of the anti-overflow mark is changed from the second state to the first state again.
In the embodiment of the invention, in the pulping process, generally, there is a foam-removing waiting period after boiling and anti-overflow, and the scheme of the embodiment can record the duration T of the foam-removing waiting period (i.e. the time from the time when the foam is removed below the anti-overflow electrode after the foam is touched to the anti-overflow electrode, or the time from the time when the foam is touched to the anti-overflow electrode to the time when the foam is separated from the anti-overflow electrode)) through a preset program. The preset program can calculate the duration T of the foam returning waiting stage by detecting the preset state of the anti-overflow collision identifier and according to the state change of the anti-overflow collision identifier.
In the embodiment of the invention, for example, whether the overflow-preventing signal is generated or not is detected, after the pulp liquid is subjected to overflow prevention, the overflow-preventing signal mark is set, the pulping process enters a waiting stage, a timer (or a counter) T1 is started, and pulp foam is gradually eliminated in the waiting process. When the program detects that the anti-overflow signal mark is reset (the pulp foam is just separated from the anti-overflow electrode at the moment), the timing time T2 of the timer at the moment is recorded, so that the duration T of the foam removing waiting stage (namely the foam removing time) of the water quality is obtained as T2-T1.
In the embodiment of the present invention, the preset program may be the program shared with the overflow detection program, or may be a dedicated defoaming test program configured to record defoaming time. The program can set a water quality detection zone bit, and when the zone bit is marked, the program enters a foam removing waiting stage: when foam is returned to wait, if the anti-overflow signal is pulled down, a second timer Time _ TM is started to continue to wait, and when the anti-overflow signal is detected to be released, timing is stopped, foam returning Time is recorded, so that the foam returning Time is calculated according to the Time recorded by the timer.
In the embodiment of the invention, the water detection time is limited by the water quality detection marker, and the water detection action is carried out when the program detects that the marker is set, so that a fixed point can be set in the flow to carry out detection and analysis on the water quality, and the timer is started and stopped by the existence of the anti-overflow signal, so that the foam removing time can be accurately calculated. And dividing the pulping water into a plurality of grades according to the measured foam withdrawal time for the adjustment of the subsequent flow.
S22, comparing the detected time length with a preset first comparison table;
in the embodiment of the present invention, in order to determine the water quality according to the duration of the foam-removing waiting stage, a comparison table, i.e., the first comparison table, in which the water quality and the foam-removing time are in one-to-one correspondence may be specified in advance through a large number of experiments or according to empirical values, so that after the duration (i.e., the foam-removing time) of the current foam-removing waiting stage is detected through step S111, the corresponding water quality may be obtained according to the first comparison table. Wherein, can include the corresponding relation of the length of time and different quality of water soluble solids total TDS value of different foam removal waiting periods in the first look-up table to and the corresponding relation of different TDS values and different quality of water grades.
In the embodiment of the invention, as shown in table 1, the soybean milk making process is taken as an example, a food processor of the same machine type is adopted, and under the same experimental condition and functional condition, the corresponding foam removing time in the soybean milk making process is obtained aiming at different water qualities.
In the embodiment of the invention, as can be seen from table 1, the difference of the TDS values of the water quality can be indirectly reflected by measuring the defoaming time.
TABLE 1
S23, determining the water quality grade of the slurry according to the comparison result;
in the embodiment of the present invention, the preset first comparison table may be as shown in table 2, and after the foam removing time in the current pulping process is determined according to the above steps, the corresponding water quality may be directly determined according to the foam removing time and the first comparison table.
| Range of foam-back Time (Time _ TM) | Water quality grading (SZ _ Level _ FY) |
| 0 is more than or equal to Time _ TM < 5 or Time _ TM < 0 | SZ_Level_FY＝0 |
| 5≤Time_TM＜10 | SZ_Level_FY＝1 |
| 10≤Time_TM＜15 | SZ_Level_FY＝2 |
| 15≤Time_TM＜20 | SZ_Level_FY＝3 |
| 20≤Time_TM | SZ_Level_FY＝4 |
TABLE 2
Secondly, according to the temperature detection during collision and overflow prevention
In the embodiment of the invention, experiments can conclude that water with high TDS value is more likely to generate slurry foam in the slurry preparation process, and the overflow-preventing temperature point of the water with high TDS value is lower than that of the water with low TDS value, so that the current water quality can be judged according to the overflow-preventing temperature point based on the phenomenon.
Optionally, the food processing process comprises: a preheating stage at the beginning of the food processing process;
as shown in fig. 3, detecting the water quality of the slurry according to the state of the slurry when the slurry foam of the slurry contacts the anti-overflow electrode may further include S31-S33:
s31, detecting the temperature of the slurry when the slurry foam of the slurry contacts the anti-overflow electrode in the preheating stage;
s32, comparing the detected slurry temperature with a preset second comparison table;
and S33, determining the water quality grade of the slurry according to the comparison result.
Wherein, can include the corresponding relation of different thick liquids temperature and different TDS values in the second look-up table to and the corresponding relation of different TDS values and different water quality grades, perhaps, directly include the corresponding relation of different thick liquids temperature and different water quality grades in the second look-up table.
In the embodiment of the invention, in the preheating stage, foams generated in the pulping process by different water qualities and the same material are different, and when water with high TDS value is used for pulping, the foams are more easily generated due to the high content of calcium and magnesium ions. In addition, because the preheating stage generally sets the program to heat the slurry to a set temperature point or to the collision and overflow prevention, for the case of heating to the collision and overflow prevention, when the program detects the collision and overflow prevention, the current temperature AD (digital) value can be recorded for distinguishing the quality of the pulping water. Specifically, the detected temperature during the overflow prevention during the preheating stage in the current pulping process is compared with a preset comparison table (i.e., the second comparison table), and the corresponding water quality grade is directly obtained according to the mapping relationship in the comparison table.
In the embodiment of the invention, as shown in table 3, a comparison table embodiment for distinguishing water quality according to different temperature values is provided.
TABLE 3
And S12, adjusting the subsequent processing technology of the food processor according to the detected different water quality.
In the embodiment of the invention, after the water quality of the current food processing process is obtained according to the scheme, the subsequent flow can be adjusted according to the current water quality so as to optimize the food processing process.

Example two
The embodiment provides a plurality of specific embodiments for adjusting the flow according to the water quality on the basis of the first embodiment.
In the embodiment of the present invention, regarding the adjustment scheme in the first embodiment, different adjustment strategies may be set according to different food processing stages, and the following description will take specific embodiments as examples.
In the embodiment of the invention, the whole food processing process can be divided into the following food processing stages in sequence: the method comprises a preheating stage (stage 1), a preliminary grinding and interval waiting stage (stage 2), a formal heating and anti-overflow collision stage (stage 3), a foam removing waiting stage (stage 4), a centralized grinding stage (stage 5) and a boiling stage (stage 6). The adjustment strategy of the subsequent process is described below for different water quality detection stages:
situation one, when water quality is detected by defoaming time in defoaming waiting stage (stage 4)
1. Adjusting pulping time in centralized crushing stage
In the embodiment of the invention, when the water quality is detected by the foam removing time in the foam removing waiting stage (stage 4), the beating time of the next food processing stage, namely the concentrated crushing stage (stage 5), can be adjusted according to the detected water quality grade. Specifically, the pulverization time can be shortened according to the following first relational expression.
The first relation may include: t1 ═ T2-nxy;
wherein, T1 is the processing time of the next food processing stage after adjustment; t2 is the processing time of the next food processing stage before adjustment; n is a preset adjusting parameter; and Y is the detected water quality grade of the slurry.
In the embodiment of the invention, in the concentrated crushing stage, the motor is used for crushing and pulping at full power, the generated vortex can push pulp foam to be high, and on the other hand, as the heat of the motor rises, the heat is transferred to the pulp while being radiated by the lower cover, and the heating effect is achieved. This scheme shortens crushing time through the difference that produces the thick liquid foam according to the quality of water difference to on the one hand reduced the height that the thick liquid foam rises, on the other hand reduced the heating effect of motor heat dissipation to the soybean milk.
2. Adjusting pulping power in centralized crushing stage
In the embodiment of the invention, when the water quality is detected by the foam removing time in the foam removing waiting stage (stage 4), the pulping power of the next food processing stage, namely the concentrated crushing stage (stage 5), can be adjusted according to the detected water quality grade. Specifically, the pulverization power may be reduced according to the following second relational expression.
The second relation may include: p1 ═ P2-mxy;
wherein P1 is the processing power (i.e. the above-mentioned crushing power or pulping power) of the next food processing stage after adjustment; p2 is the processing power of the next food processing stage before adjustment; and m is a preset adjusting parameter.
In the embodiment of the invention, the height of the vortex generated in the beating process can be controlled by adjusting the beating rotating speed (i.e. power) according to the second relational expression. When the water quality grade measured in the foam withdrawal waiting stage is higher, pulp foam is not easy to withdraw, the height of a vortex generated when the pulping power is high is higher, and the pulp foam is easy to push out to cause pulp overflow. The embodiment scheme adjusts the pulping rotating speed according to the water quality grade, and the vortex height can be adjusted, so that the pulp overflowing phenomenon is avoided.
3. Adjusting the cooking power in the cooking stage
In the embodiment of the invention, when the water quality is detected through the foam removing time in the foam removing waiting stage (stage 4), the pulping power of the subsequent food processing stage, such as the cooking stage (stage 6), can be adjusted according to the detected water quality grade. Specifically, the boiling power can be reduced according to the following third relational expression.
The third relationship may include: p3 ═ P4-kxy;
wherein P3 is the processing power (i.e. the above boiling power) of the adjusted boiling stage; p4 is the processing power of the boiling stage before adjustment; k is a preset adjusting parameter.
In the embodiment of the invention, the self-adaptive adjustment of the heating power is realized by adjusting the heating time of the fire (namely high power and low power) according to the water quality classification data. The boiling power can be kept unchanged at the stage, after the heating is carried out for a period of time, the boiling is realized by pausing for a period of time (for example, the heating is stopped for 1 second and for m seconds), and the power is indirectly adjusted by adjusting the heating stop time.
In the embodiment of the invention, the boiling power of the food processor can not be automatically adjusted by the difference of water quality at present, and aiming at the water quality with much foam, the boiling power set in the process of pulping aims at the water quality with common tap water, and aiming at the water quality with easy foaming in Heilongjiang and Shandong, the fixed boiling power has the problem of pulp overflow. According to the scheme, the cooking power is adaptively adjusted through the water quality classification SZ _ Level _ FY, the cooking power is reduced for the water quality which is easy to foam and difficult to remove pulp foam according to the actual condition, and the cooking power can not be adjusted for the normal water quality such as common tap water, purified water and the like, so that the pulp overflowing problem of the water quality in individual areas is avoided, and meanwhile, the period of normal water quality pulping is not influenced.
4. Adjusting the waiting time (or interval for short) after the central comminution stage
In the embodiment of the invention, when the water quality is detected by the foam removing time in the foam removing waiting stage (stage 4), the interval waiting time between the subsequent food processing stages, such as the interval between the concentrated crushing stage (stage 5) and the boiling stage (stage 6), can be adjusted according to the detected water quality grade. Specifically, the interval waiting time may be increased according to the following fourth relational expression.
The fourth relation may include: t3 ═ T4+ hxy;
wherein T3 is the adjusted interval time; t4 is the interval time before adjustment; h is a preset adjusting parameter; and Y is the detected water quality grade of the slurry.
In the embodiment of the present invention, after the pulping process enters stage 5, the wait process may set the adjustment flag SZ _ rev, and when the flag is set, set T3 to T4+ hxy.
In the embodiment of the invention, in the concentrated crushing stage (stage 5), due to the difference of water quality, the pulp foam height generated in the pulping process is greatly different, the pulp foam is slowly withdrawn in the pulping process of the water quality with high TDS value, the interval time is adjusted according to the water quality grade, the flow adjustment of different water in the pulping process can be ensured according to the actual condition, the pulp overflow risk is reduced, and the total pulping time can be optimized according to the water quality. The traditional pulping process is provided with fixed foam-removing waiting time, so that the water quality condition is not always considered, the pulping time is too long or the overflow phenomenon is frequently caused, and the food processing process cannot reach a better state.
Case two, when the water quality is detected by the temperature of the slurry at the time of collision with the overflow prevention in the preheating stage (stage 1)
1. Adjusting the beating time of the preliminary grinding and interval waiting stage (stage 2)
In the embodiment of the present invention, when the water quality is detected by the temperature of the slurry at the time of overflow prevention in the preheating stage (stage 1), the beating time of the next food processing stage, i.e., the preliminary grinding + interval waiting stage (stage 2), may be adjusted according to the detected water quality level.

Specifically, the pulverization power may be reduced according to the following second relational expression.
The second relation may include: p1 ═ P2-mxy;
wherein P1 is the processing power (i.e. the above-mentioned crushing power or pulping power) of the next food processing stage after adjustment; p2 is the processing power of the next food processing stage before adjustment; and m is a preset adjusting parameter.

3. Adjusting the cooking power in the cooking stage
In the embodiment of the invention, when the water quality is detected by the temperature of the slurry during overflow prevention in the preheating stage (stage 1), the pulping power of the subsequent food processing stage, such as the cooking stage (stage 6), can be adjusted according to the detected water quality level.

In the embodiment of the invention, the boiling power of the food processor can not be automatically adjusted by the difference of water quality at present, and aiming at the water quality with much foam, the boiling power set in the process of pulping aims at the water quality with common tap water, and aiming at the water quality with easy foaming in Heilongjiang and Shandong, the fixed boiling power has the problem of pulp overflow. According to the scheme, the cooking power is adaptively adjusted through the water quality classification SZ _ Level _ FY, the cooking power is reduced for the water quality which is easy to foam and difficult to remove pulp foam according to the actual condition, and the cooking power can not be adjusted for the normal water quality such as common tap water, purified water and the like, so that the pulp overflowing problem of the water quality in individual areas is avoided, and meanwhile, the period of normal water quality pulping is not influenced.
4. Adjusting the Interval waiting time (or Interval for short) in the preliminary grinding + Interval waiting phase (phase 2)

The fourth relation may include: t3 ═ T4+ hxy;
wherein T3 is the adjusted interval time; t4 is the interval time before adjustment; h is a preset adjusting parameter; and Y is the detected water quality grade of the slurry.
In the embodiment of the present invention, after the pulping process enters stage 2, the wait process may set the adjustment flag SZ _ rev, and when the flag is set, set T3 to T4+ hxy.

In the embodiment of the invention, the boiling points of the same water are different at different altitudes, so that the measured temperature values can be deviated due to different altitudes of different regions when the temperature during the pre-heating stage and the overflow prevention are detected. According to the scheme, after the influence of the altitude on the water boiling point is taken into consideration, the influence of the altitude difference on the water boiling point is eliminated, whether water boils or not is judged through the change of the water temperature rising slope, the deviation FY _ Rev of the boiling point and the zero altitude corresponding boiling point AD value of the food processing machine in a specific area is calculated, the preheating anti-overflow temperature is corrected (the anti-overflow temperature in other processing stages can be corrected), and the corrected temperature value is adopted to grade the water quality for regulating the subsequent flow.
In the embodiment of the present invention, if the temperature at which water boils at the current altitude is FD _ AD, and the AD corresponding to the boiling point of 100 ℃ at Zero altitude is FD _ Zero _ AD (any currently practicable method can be used for measurement, and no limitation is imposed on a specific measurement scheme, for example, a heating slope method is used), the correction value FY _ Rev is obtained, where FY _ Rev is | FD _ Zero _ AD-FD _ AD |.
