Specific embodiment
To make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and it is embodied Mode does further in detail a kind of unfreezing control method, thawing control device and computer storage medium provided herein Description.
It is thawed, frozen heat foods can be thawed to -2 DEG C~35 DEG C to food using thawing control device, And currently during carrying out heating defrosting to food, it is easy due to heating the problem of unevenly leading to food hot-spot, It requires to carry out turn-over to food at this time, increases the complexity of user's operation.And the application propose unfreezing control method, it can be achieved that The defrosting that is evenly heated of thawed foodstuff is treated, user is not necessarily to carry out turn-over operation to food in course of defrosting, reinforces effect of thawing Fruit simplifies user's operation.
It is the flow diagram of one embodiment of the application unfreezing control method referring specifically to Fig. 1, Fig. 1.The present embodiment solution Freeze in control method and two stages defrostings are carried out with the first heating power and the second heating power respectively, wherein the first heating function Rate is greater than the second heating power.Unfreezing control method includes the following steps.
S101: treating thawed foodstuff with the first heating power and carry out first stage defrosting, until to thawed foodstuff first The first temperature rise that stage thaws reaches the first temperature rise standard.
It carries out thawing in the present embodiment and can be microwave heating defrosting, be also possible to heat pipes heat defrosting, therefore heat function Rate can correspond to be heating element output power.
The first stage, which thaws, in this step is carried out with biggish first heating power, and the big of thawed foodstuff is treated in realization In power ice-breaking, such as the meat of the freezing at -18 DEG C of refrigerator, the freezing rate of water is about 90%, i.e., most of water becomes in meat Ice crystal, but still there is the fraction water not to be frozen.Fraction water is carried out using biggish first heating power in this step Heating fill can, since the thermal conductivity of water is 0.582W/ (m*k), the thermal conductivity of ice is 2.326W/ (m*k), about the four of water times, Thus fraction water can realize that quickly heat transmitting, the stage temperature rise are more rapid by most of ice after filling energy.
If but continue to be heated with the first heating power of increasing, it be easy to cause certain position heatings too fast, other The problem of position or frozen state, such as surface overheat, inside is in frozen state.Thus with temperature rise in the present embodiment It thaws to control the first stage, i.e., when carrying out first stage defrosting, the first temperature rise to thawed foodstuff is detected, when the first temperature rise When reaching the first temperature rise standard, i.e., heating defrosting is no longer carried out with the first heating power, but carry out step S102, with lesser Second heating power carries out heating defrosting.
S102: second stage defrosting is carried out with the thawed foodstuff for the treatment of of the second heating power on-off type.
When being thawed with smaller second heating power, carried out by the way of on-off type in the present embodiment.It is i.e. first Guide, which passes to the second heating power and treats thawed foodstuff, carries out heating defrosting, is then turned off the heating solution that thawed foodstuff is treated in pause Freeze, the process for suspending heating can make the temperature to thawed foodstuff realize whole machine balancing.
Since second stage defrosting is in order to avoid heating too fast caused hot-spot problem, rank is heated in conducting The heating time of section is also shorter.Only carry out a complete defrosting that second stage defrosting generally cannot achieve food, thus this reality It applies in example and is repeatedly carried out with the second stage defrosting of the second heating power on-off type.
S103: repeating second stage and thaw, until the second temperature rise thawed to thawed foodstuff in last time second stage Reach the second temperature rise standard.
The number of repetition that second stage is thawed is also to be controlled by temperature rise, after terminating second stage every time and thawing, The second temperature rise thawed to thawed foodstuff in second stage can be calculated, when the second temperature rise reaches the second temperature rise standard, is then tied Beam thaws.
Different temperature rise variations can embody food in the different phase of defrosting, complete to thaw fast, i.e., ice crystal becomes completely The temperature rise of Cheng Shuihou, water become larger, i.e. gradually completing with defrosting, and the temperature change that second stage is thawed can be increasing, because And controlled by the second temperature rise standard, i.e., when the second temperature rise reaches low temperature temperature rise standard, it is believed that defrosting is completed, in food Ice crystal become water completely, food temperature reaches expected thaw point.
It carries out heating ice-breaking in the present embodiment by the first heating power first, and is controlled using the first temperature rise standard First stage thaws, and avoids hot-spot;Then second stage defrosting is repeated by the second heating power on-off type, protected The uniformity of heating is demonstrate,proved, and controls the number of repetition of second stage defrosting using the second temperature rise standard, being thawed with control terminates. First temperature rise standard and the second temperature rise standard determined by food material itself, thus in the present embodiment and without limitation.
The detailed process of each step is referring to Fig. 2, Fig. 2 is the detailed of unfreezing control method embodiment shown in Fig. 1 in Fig. 1 Flow diagram.Unfreezing control method shown in Fig. 2 specifically includes following steps.
S201: initial temperature of the detection to thawed foodstuff.
Its initial temperature T will be first being detected when thawed foodstuff is put into thawing apparatuss, can specifically pass through thawing apparatus sheet Temperature sensor set by body, such as infrared sensor detection.It is realized in below the step of also by the temperature sensor Temperature detection.
S202: thawed foodstuff is treated with the first heating power and carries out first stage defrosting, is detected to the current of thawed foodstuff Temperature.
After thawed foodstuff is put into thawing apparatus, first stage ice-breaking heating solution is being carried out to it with the first heating power Freeze, the first heating power p during being somebody's turn to do1It can be 1000w.In the process, working as to thawed foodstuff need to be detected in real time Preceding temperature Te, i.e., periodically detect the temperature to thawed foodstuff.
S203: the difference of Current Temperatures and initial temperature is calculated to judge whether the first temperature rise reaches as the first temperature rise First temperature rise standard.
After periodically detecting Current Temperatures, after detecting Current Temperatures every time, be required to calculate Current Temperatures with The difference of initial temperature obtains the temperature rise generated when thawed foodstuff when current state is compared to original state, i.e. the first temperature rise △T1=Te-Ts
Then start to judge whether first temperature rise reaches the first temperature rise standard dT after obtaining the first temperature rise1If reaching, tie The beam first stage thaws, and carries out step S204.If not up to, continuing first stage defrosting, that is, returning to step S202, continue with First heating power treats thawed foodstuff and carries out first stage defrosting.When the present embodiment is applied to the defrosting of meat, the first temperature rise Standard dT1It is 4 DEG C.
S204: thawed foodstuff is treated with the second heating power and is heated.
After terminating first stage defrosting, that is, start with lesser second heating power p2It is heated, wherein when heating Between make heat energy meet energy preset requirement, which is calculated by the second heating power and heating time.This In step S204, with lesser second heating power, and with fixed heat energy to be heated, it can reduce and treat defrosting The heating speed of food, avoiding the problem that heating focuses leads to hot-spot.In the present embodiment, the second heating power p2It is set as 400w。
Fixed heat energy can be arranged according to the material of food, and when default can not exhaustive all materials consolidate Determine heat energy, therefore is arranged in the present embodiment using the unit heat energy that the first stage thaws.
Specifically, it after the completion of thawing in the first stage, calculates to total heat energy Q consumed by thawed foodstuff1, can root It is calculated according to the first heating power;Then according to total heat energy Q1With the first temperature rise △ T1Unit of account heat energy △ Q=Q1/ △T1.Fixation heat energy in this step S204 then can be equal to unit heat energy △ Q or be less than unit heat energy.
S205: pause is treated thawed foodstuff and is heated.
For after thawed foodstuff provides fixed heat energy, suspended by this step S206 and heated, so that wait the food that thaws Object bulk temperature balance, so that homogeneous heating.And after thawing in the first stage, to which still there are more ice in thawed foodstuff Crystalline substance, thus in pause stage, ice crystal heat transfer is very fast, so that will appear the case where temperature is fallen after rise to thawed foodstuff, that is, there is temperature drop, It then needs to provide heat energy in time at this time and be heated.
Thus in this step S205, time out need to meet preset requirement, such as time out meets this section of time institute The temperature drop of generation is less than or equal to default temperature drop threshold value, if having been above temperature drop threshold value, and defrosting is also not finished, then passes through step S204 continues to provide heat energy to thawed foodstuff.Certainly, also settable regular time threshold value is as time out.In advance If the mode that temperature drop threshold value and preset time threshold combine, when the second stage of several wheels is thawed in front, use to preset temperature drop Threshold value controls, and a few wheel second stage for terminating fastly defrostings is changed to control with preset time threshold.This is because Incipient earlier stage, it is also more to the ice crystal in thawed foodstuff, and last stages, ice crystal are fewer and fewer, also substantially no longer It will appear temperature drop;Thus earlier stage determines that last stages are determined using preset time threshold using default temperature drop threshold value.Front Stage and last stages can then judge that ice crystal and the water mixing of earlier stage, temperature rise is smaller, the ice of last stages by temperature rise Brilliant smaller, temperature rise is also larger.
S206: the second temperature rise thawed to thawed foodstuff in second stage is calculated, judges whether the second temperature rise reaches second Temperature rise standard.
After completing second stage defrosting every time, the second temperature rise to thawed foodstuff can be calculated, and judge second temperature rise Whether second temperature rise standard is reached, if reaching, then it represents that defrosting is completed, therefore terminates to thaw;If not up to, then carrying out one Secondary second stage is thawed, that is, returns to step S204.
In ice water solid-liquid phase change, temperature rise is slower, and temperature rise is handed over fastly after the completion of ice water solid-liquid phase change, is detected at this time Temperature rise becomes larger, and therefore, can be sentenced by judging whether the second temperature rise reaches the second temperature rise standard in this step S206 Disconnected completion of whether thawing.
After the completion of thawing in the first stage in the present embodiment, is thawed by repeating second stage, avoids hot-spot, Guarantee heating uniformity;And in second stage defrosting, pause heating time is controlled using temperature drop, to treat solution in time Freeze food supplementary heating energy, to improve the heating defrosting efficiency to thawed foodstuff.
The present embodiment controls heating course of defrosting by the variation of temperature change and heat energy, is with meat below Example, does entire course of defrosting the explanation in principle.Referring to Fig. 3, the temperature thermal change that Fig. 3 is meat freezing process is shown It is intended to.Course of defrosting, that is, freezing process inverse process, thus can be by being studied freezing process to carry out to course of defrosting Control.Such as the defrosting to meat, the freezing process of meat in Fig. 3 is seen first.
In the freezing process, the heat of meat releasing are as follows:
Q=m [cp1(T1-Tp)+wψr+cp2(Tp-T2)]
Wherein, Q is total exothermic energy, and m is the quality of meat, cp1And cp2Respectively meat freeze front and back specific heat capacity, ψ For freezing rate, r is the latent heat that water forms ice, T1、Tp、T2Respectively initial temperature, phase transition temperature, final temperature.When freezing, Meat heat release is broadly divided into three phases, the water exothermic phase that moisture cools down but do not freeze, and water is converted to the phase transformation heat release rank of ice After the completion of section and phase change transition, ice continues the ice exothermic phase of cooling;From the figure 3, it may be seen that the latent heat of phase transformation exothermic phase is most Greatly, Exotherm Time longest, phase temperature variation is smaller, and in water exothermic phase and ice exothermic phase, temperature change is larger.? In entire freezing process, the variation of exothermic energy is more uniform.
Relative to the freezing process, course of defrosting also corresponds to it with 3 endothermic phases.Course of defrosting is being carried out to meat In, by taking microwave thawing as an example, microwave heating principle are as follows:
Q=55.6 × 10-12E2fvε″r△ t=mcp△T
Wherein, E is electromagnetic field intensity, and f is microwave frequency, and V is volume, and Δ t is heating time, and Δ T is temperature rise, cpFor than Thermal capacitance, ε "rFor dielectric loss factor.
Temperature rise slope k is obtained as a result, are as follows:
K=△ T/ △ t=(55.6 × 10-12E2fv/m)×(ε″r/cp)
The dielectric loss factor of water is much larger than the dielectric loss factor of ice, such as the dielectric loss factor of -13 DEG C of ice is The dielectric loss factor of 0.0028,25 DEG C of water is 12.3;And the specific heat capacity of ice is the half of water, the specific heat capacity of water is 4.2kJ/ (kg × DEG C), the specific heat capacity of ice is 2.1kJ/ (kg* DEG C);Therefore by the formula of the above temperature rise slope k it is found that same heating power Under, kWaterMuch larger than kIce
Therefore, the ice thaw stage corresponds to the ice exothermic phase of freezing process in course of defrosting, at this time in meat containing big Ice crystal and little water are measured, therefore can be heated by biggish first heating power, i.e., the water inside meat piece is quickly filled Can, then by the ice of high thermoconductivity, fast speed heat transmitting is carried out, so that this stage temperature rise is more rapid.
And when temperature rise is to a certain temperature, the ice crystal in meat can progress into solid-liquid phase change state, therefore to prevent Hot-spot adjusts heating power, using lesser second heating power, carries out the on-off type heating solution of constant heat energy Freeze.
The process includes that ice water thaws the stage, and the phase transformation exothermic phase of corresponding freezing process utilizes the list in ice thaw stage The heat energy of position temperature rise to carry out on-off type heating to meat, thaws initial stage in stage in the ice water, there is also more in meat Ice crystal, the heat transmitting in meat is very fast, is easy to appear the case where temperature is fallen after rise after the heating, therefore fall after rise by monitoring temperature To carry out energy supply to meat piece in time.
The process further includes the water thawing stage, and the water exothermic phase of corresponding freezing process feeds identical heat energy, ice When aqueous phase, meat piece temperature rise is slow, and after being fully converted to water, meat piece temperature rise is fast, and temperature rise at this time can become larger.Therefore it records every Temperature rise after secondary on-off type heating is thawed and is completed when single temperature rise is greater than the second temperature rise standard.Wherein, the second temperature rise standard Can and obtained according to experiment.
It is realized using temperature energy variation to solution based on temperature energy variation principle, the present embodiment in the above course of defrosting Freeze control, ensure that the uniform high-efficiency of course of defrosting.The specific implementation of the present embodiment unfreezing control method by hardware device and Software architecture is realized.
