Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A pressure cooking appliance, a control method thereof and an apparatus thereof according to embodiments of the present invention will be described below with reference to the accompanying drawings.
It is understood that, according to the common sense of physics, the boiling point, i.e. the temperature at which the saturated vapour pressure of a liquid is equal to the external pressure, when the liquid boils, the saturated vapour pressure in the bubbles formed inside it is equal to the externally applied pressure, i.e.: pv is Pe +2 σ/R, Pv is the bubble internal saturation pressure, Pe is the liquid external air pressure (pan internal air pressure), σ is the bubble surface tension, and R is the bubble radius. Thus, the higher the atmospheric pressure, the higher the boiling point, and the lower the reverse atmospheric pressure, the lower the boiling point. By utilizing the principle, the air pressure Pe in the pot is reduced, so that the boiling temperature is reduced to be close to the temperature at which rice does not start gelatinization or just starts gelatinization, the rice grains are disturbed by utilizing the separation bubbles generated by boiling, the rice grains are not adhered to each other under the disturbance condition, and the agglomeration is avoided. Meanwhile, dense bubble channels are formed by utilizing the separated bubbles generated by boiling to convey heat and moisture upwards, so that the rice grains are heated and absorb water more uniformly.
Referring to fig. 1, the pressure cooking appliance of the embodiment of the present invention includes a lid 1, a pot 2, an air extracting device 3, and a control device 4. The pressure cooking appliance may be a pressure rice cooker or the like. Wherein, the air extracting device 3 can be arranged in the cover body 1 or the pot body 2. Specifically, in the heating process, the control device 4 controls the air extracting device 3 to extract air in the pot body 2 and discharge the air to the outside of the pot body 2, so that negative pressure is formed in the pot body, food mixtures such as rice water are boiled at a lower temperature (the temperature of rice grains which are gelatinized but not bonded into a mass) and boiling bubbles are generated, the rice grains are loosened and not bonded through bubble disturbance, the heating uniformity of rice is ensured, and the boiling effect is optimal.
Based on the pressure cooking appliance in the embodiment of fig. 1, the embodiment of the invention provides a control method of the pressure cooking appliance.
Fig. 2 is a flowchart of a control method of a pressure cooking appliance according to an embodiment of the present invention. As shown in fig. 2, the method for controlling a pressure cooking appliance includes the steps of:
s201, acquiring the temperature in the pressure cooking appliance.
That is, the temperature inside the cooking utensil (pot) is detected in real time during the cooking process of the pressure cooking utensil, wherein the cooking process comprises a preheating and water absorption stage, a heating and boiling stage, a high-temperature boiling stage and a stewing stage (a cooking completion stage).
Specifically, the temperature in the pressure cooking appliance can be acquired in real time through a temperature acquisition module such as a temperature sensor arranged at the bottom of the pot body or can be acquired in real time through a temperature acquisition module such as a temperature sensor arranged in the cover body.
It is understood that the cooking process of the pressure cooking appliance during cooking may include, but is not limited to, a pre-heating water absorption phase, a warming boiling phase, a high-temperature boiling phase and a stewing phase, and may not include the pre-heating water absorption phase and/or the stewing phase. Wherein, as shown in fig. 3, the heating and boiling stage will be described in detail in the following examples; before entering the temperature-rising boiling stage, the pressure cooking appliance firstly enters a preheating water absorption stage, and rice grains are preheated and absorbed in the preheating water absorption stage, so that the cooking time can be shortened, and the taste of the rice cooked by the pressure cooking appliance can be improved; after the temperature-raising boiling stage, the high-temperature boiling stage and the stewing stage are carried out, wherein the inside of the pot body is in a non-negative pressure state such as a normal pressure state in the high-temperature boiling stage, the inside of the pot body is in a normal pressure state in the high-temperature boiling stage, and rice water in the pot body can be kept boiling at a higher temperature, namely, the rice water is kept boiling at a temperature of a boiling point (about 100 ℃) under the external atmospheric pressure, so that the rice is cooked.
S202, judging whether the temperature in the pressure cooking appliance is larger than a first preset temperature threshold value or not. Wherein, the value range of the first preset temperature threshold is 55-65 ℃, and the optimal value range is 60 ℃.
S203, if the temperature in the pressure cooking appliance is larger than a first preset temperature threshold value, further judging whether the temperature in the pressure cooking appliance is in a first preset temperature range. Wherein, the first preset temperature range is between a first preset temperature threshold and a second preset temperature threshold, and the value range of the second preset temperature threshold is 70-80 ℃, and can be preferably 75 ℃.
And S204, if the temperature in the pressure cooking appliance is in a first preset temperature range, controlling the pressure in the pressure cooking appliance in the first pressure range.
And S205, if the temperature of the pressure cooking appliance is larger than the first preset temperature range, further judging whether the temperature in the pressure cooking appliance is in a second preset temperature range. Wherein the second preset temperature range is between the second preset temperature threshold and a third preset temperature threshold, and the value range of the third preset temperature threshold is 85-95 ℃, and preferably 90 ℃.
S206, if the temperature in the pressure cooking appliance is within the second preset temperature range, controlling the pressure in the pressure cooking appliance to be within the second pressure range. Wherein the pressure values of the second pressure range are greater than the pressure values of the first pressure range.
For example, referring to fig. 3, the temperature rise interval of the pressure cooking appliance from 60 ℃ to 98 ℃ is a temperature rise boiling phase, which can be divided into two phases T1 and T2 according to the temperature, wherein the T1 phase with the lower temperature is the interval of the pressure cooking appliance from 60 ℃ to 75 ℃, and the T2 phase with the higher temperature is the interval of the pressure cooking appliance from 75 ℃ to 90 ℃.
The scheme is obtained through a large number of experiments: in order to optimize the boiling effect, the pressure Pe in the pressure cooking utensil and the temperature T in the pressure cooking utensil in the intervals of T1 and T2 in the temperature rising boiling stage have the corresponding relation of 0.16 < Pe/T < 1.6. The average value of the air pressure in the pressure cooking utensil corresponding to the T1 stage is
The average value of the air pressure in the pressure cooking utensil corresponding to the T2 stage is
Then
Specifically, during the cooking process of the pressure cooking appliance, the temperature in the pressure cooking appliance is obtained in real time, and the temperature is compared with a first preset temperature threshold value, such as 60 ℃, so that whether the cooking process of the pressure cooking appliance enters a temperature rising boiling stage or not is judged. When the temperature in the pressure cooking appliance is higher than 60 ℃, which indicates that the cooking process of the pressure cooking appliance enters a temperature-raising boiling stage, it is further determined whether the temperature in the pressure cooking appliance is higher than 60 ℃ and lower than 75 ℃, that is, it is determined whether the temperature in the pressure cooking appliance is in a stage T1 where the temperature is lower. When the temperature in the pressure cooking appliance is more than 60 ℃ and less than 75 ℃, namely in the T1 stage of lower temperature, the control device of the pressure cooking appliance controls the air extracting device to extract the air in the pot body and discharge the air out of the pot body so as to control the pressure in the pressure cooking appliance in a first pressure range.
When the temperature in the pressure cooking appliance is greater than or equal to 75 ℃, whether the temperature in the pressure cooking appliance is greater than 75 ℃ and less than 90 ℃ is further judged, namely whether the temperature in the pressure cooking appliance is in a stage T2 when the temperature is higher. When the temperature in the pressure cooking appliance is more than 75 ℃ and less than 90 ℃, namely in the T2 stage of higher temperature, the control device of the pressure cooking appliance extracts the air in the pot body and discharges the air out of the pot body so as to control the pressure in the pressure cooking appliance in the second pressure range.
The following describes, with reference to a specific example, a cooking process of the pressure cooking appliance in a temperature-raising boiling stage, and the boiling effect when the pressure (pressure in the cooker) in the pressure cooking appliance is controlled in different first and second pressure ranges respectively in the stages T1 and T2.
Example one:
the pressure in the cooker was controlled to a first pressure range of 10kPa to 80kPa at stage T1 and to a second pressure range of 30kPa to 90kPa at stage T2, and the results of the experiments were as shown in Table 1 below:
TABLE 1
Example two:
in order to achieve better negative pressure in the cooker, reduce the cost of the air extractor and ensure the boiling effect, in this example, the pressure in the cooker is controlled to be in the first pressure range of 20kPa-70kPa during the period T1, and the pressure in the cooker is controlled to be in the second pressure range of 40kPa-90kPa during the period T2, and the experimental results are shown in the following table 2:
TABLE 2
Example three:
in this example, the evacuation device can be a common micro vacuum pump, which is low in cost, and in order to achieve better boiling effect and better heating uniformity effect, the pressure in the cooker is controlled to be in the first pressure range of 40kPa-60kPa at stage T1, and the pressure in the cooker is controlled to be in the second pressure range of 50kPa-90kPa at stage T2, and the experimental results are shown in table 3 below:
TABLE 3
Example four: as can be seen from Table 3, if the design is made according to the parameters shown in Table 3, the boiling and heating effects are ideal, and in order to further reduce the cost, the lower end product can also achieve the improvement of the heating performance caused by the reduction of the boiling point due to the vacuum pumping, in this example, the pressure in the cooker is controlled to be in the first pressure range of 60kPa-80kPa during the T1 stage, and the pressure in the cooker is controlled to be in the second pressure range of 70kPa-90kPa during the T2 stage, and the experimental results are shown in the following Table 4:
TABLE 4
As indexes for evaluating the uniform heating and water absorption performance of the rice in the industry are mainly the number of boiling holes and the nine-point moisture deviation rate. The judgment criteria for the number of boiling holes are: the maximum side length of the opening is 5mm, the middle of the hole is in a spiral triangle shape, and the middle is not blocked by rice grains, namely the boiling hole is formed. Generally, the more uniform the boiling holes, the more uniform the rice boils. Nine-point moisture deviation ratio: as shown in fig. 4, the water content of the cooked rice at nine different positions is measured, and the deviation of the water content at the nine different positions is the deviation of the water content at the nine different positions, and the smaller the deviation value of the water content at the nine different positions is, the more uniformly the cooked rice at the different positions absorbs water and is heated.
Different heating effects and mouthfeel effects of the cooked rice can be obtained through different embodiments.
The first embodiment is as follows:
the pressure in the cooker is increased by an air extractor in the T1 stage (i.e. 60-75 deg.C interval)
Maintaining 80kPa, and making the pressure in the cooker by an air extractor at T2 stage (i.e. 75-90 deg.C)
When cooking 2, 4 and 8 cups of rice, respectively, while maintaining 90kPa, the effects achieved are shown in table 5 below:
TABLE 5
As can be seen from Table 5, the rice uniformity effect and the rice texture effect of example one did not achieve particularly desirable effects.
Example two:
the pressure in the cooker is increased by an air extractor in the T1 stage (i.e. 60-75 deg.C interval)
Maintaining 65kPa, and introducing at T2 stage (i.e. 75-90 deg.C)The pressure in the cooker is enabled to be exerted by an air exhaust device
When cooking 2, 4 and 8 cups of rice, respectively, while maintaining 75kPa, the effects achieved are shown in table 6 below:
TABLE 6
As can be seen from Table 5, the rice uniformity and texture effects of the cooked rice of example two were improved compared to those of example one, and were of moderate level.
Example three:
the pressure in the cooker is increased by an air extractor in the T1 stage (i.e. 60-75 deg.C interval)
Maintaining 40kPa, and making the pressure in the cooker at T2 stage (i.e. 75-90 deg.C) by air extractor
When cooking 2, 4 and 8 cups of rice, respectively, while maintaining 60kPa, the effects achieved are shown in table 7 below:
TABLE 7
As can be seen from Table 7, the rice uniformity effect and the rice texture effect of example III were improved to a higher level than those of example II.
Example four:
the pressure in the cooker is increased by an air extractor in the T1 stage (i.e. 60-75 deg.C interval)
Maintaining 40kPa, and making the pressure in the cooker at T2 stage (i.e. 75-90 deg.C) by air extractor
When cooking 2, 4 and 8 cups of rice, respectively, while maintaining 60kPa, the following table 8 is shown:
TABLE 8
As can be seen from Table 8, the rice uniformity and taste of the cooked rice according to the fourth embodiment are also at a high level, but the number of boiling holes is reduced, which is associated with the separation and combination of the early bubbles, and the bubbles are easily gathered into large bubbles penetrating through the cooked rice, and at the same time, the cost of the air-extracting device and the pressure-bearing structure is greatly increased to reach the low pressure value of 20kPa, which is not the optimal choice.
In practical applications, the parameters can be set according to actual conditions, but the parameters of the third embodiment are preferred as the optimal parameters in combination with the effects.
In another embodiment of the present invention, as shown in fig. 5, the method for controlling a pressure cooking appliance includes the steps of:
s501, acquiring the temperature in the pressure cooking appliance.
Wherein, the accessible sets up the temperature that obtains the module like temperature sensor in the pot body bottom and obtains the temperature in the pressure cooking utensil in real time or obtains the module like temperature sensor through the temperature that sets up in the lid and obtain the temperature in the pressure cooking utensil in real time.
S502, judging whether the temperature in the pressure cooking appliance is larger than a first preset temperature threshold value or not.
S503, if the temperature in the pressure cooking appliance is greater than a first preset temperature threshold and less than a second preset temperature threshold, controlling the pressure change value of the pressure cooking appliance in a first change range, wherein the first change range takes the pressure corresponding to the first preset temperature threshold as a reference. In one embodiment of the invention, the first variation range may be 20 kPa.

In one embodiment of the invention, the second variation range may be 20 kPa.
Specifically, during the cooking process of the pressure cooking appliance, the temperature in the pressure cooking appliance is obtained in real time, and the temperature is compared with a first preset temperature threshold value, such as 60 ℃, so that whether the cooking process of the pressure cooking appliance enters a temperature rising boiling stage or not is judged. When the temperature in the pressure cooking appliance is greater than a first preset temperature threshold value, such as 60 ℃, and less than a second preset temperature threshold value, such as 75 ℃, namely in a stage T1 where the temperature is lower, the control device of the pressure cooking appliance controls the air extraction device to extract air in the pot body and discharge the air to the outside of the pot body, so as to control the pressure variation value in the pressure cooking appliance within a first variation range taking the pressure corresponding to the first preset temperature threshold value as a reference.

When the temperature in the pressure cooking appliance is greater than a second preset temperature threshold, such as 75 ℃, and less than a third preset temperature threshold, such as 90 ℃, namely in a stage T2 where the temperature is higher, the control device of the pressure cooking appliance also controls the air extraction device to extract air in the pot body and discharge the air to the outside of the pot body, so as to control the pressure variation value in the pressure cooking appliance within a second variation range taking the pressure corresponding to the second preset temperature threshold as a reference. For example, referring to fig. 3, when the temperature in the pressure cooking device is 75 ℃, the pressure in the corresponding pressure cooking device is 50kPa, and at this time, the pressure in the pressure cooking device can be controlled to be in the range of 50kPa to 70kPa, so that the boiling point in this stage is 85 ℃ to 96 ℃, the pot is continuously boiled and generates a large amount of steam, the pressure Pe in the pot is slowly increased, the temperature in the pot is also increased, and the rice water can maintain a good heat receiving effect.
When the temperature in the pressure cooking appliance is higher than a third preset temperature threshold value, such as 90 ℃, the control device of the pressure cooking appliance controls the air exhaust device not to work so as to enable the pressure in the pressure cooking appliance to rise rapidly, thus the boiling can be realized at a lower temperature, and meanwhile, the optimal boiling effect can be achieved.

In one embodiment of the invention, the first variation range may be 20 kPa.
