Embodiment:
Figure 1 shows that electrical heating controllable temperature Range structure block diagram.Electromagnetic oven with control module 2 with the electrical heating controllable temperature stove and accessory 1 of control module.The heating power of control module 2 control electromagnetic ovens; Control module 2 connects respectively temperature sensor 3 and module storage 4, stores culinary art module 50, temperature deviation digestion submodule 51, temperature compensation module 52 and high temperature limit module 53 in module storage 4; Temperature sensor 3 adopts embedded PT1000 temperature sensor, be installed on the contact-making surface of electromagnetic oven and pot body, culinary art module 4 contains the software control procedure according to the manufacture craft establishment of determined temperature of middle medium scope, Temperature Control Model U=P-k (t-T) and various vegetables, and temperature deviation digestion submodule 51 contains the control program of eliminating the outer temperature deviation of technological process; 52 pairs of starting stages of temperature compensation module delimited temperature compensation range, and observed temperature and normal temperature are compared, and in the time of in the design temperature scope dish of cooking carried out proportional compensation or the fixed value compensation of process time; High temperature limit module 53 realizes high temperature limit by setting limiting value; Control module 2 also has overcurrent, overvoltage, overheat protector concurrently, and unloaded the detection reported to the police, the function such as communicate by letter with host computer.
In cooking container (being specially pot in the present embodiment) bottom and electromagnetic oven contact-making surface mounting temperature sensor 3, cooking bottom temperature is carried out real-time detection, so that control module 2 in time and exactly collects current temperature, process according to control program rapidly, constantly adjust to suitable power, thereby realize the purpose of control temperature.In addition outer pan body sealing is subjected to ectocine hardly, namely can think, temperature of boiler approximates pot required temperature of interior food materials, thereby the cooking methods whole process is carried out artificial intelligence control, has realized intelligent cooking.
In the intelligent cooking practical operation, the factor (the outer temperature deviation of technological process) that affects the dish cooking quality has:
1. temperature deviation
1), the deviation of food materials when culinary art initial temperature, such as the raw material of preparation with condiment because the storage environment is different from cooking environments, when initial culinary art, have certain temperature deviation.
2), the temperature of boiler deviation, namely because the pot storage environment is different, and cause pot temperature of boiler when culinary art is initial also different.When the operator is disposed at food materials in the pot according to the garnishes handbook, when holding point was single, pot and food materials left in the refrigerator and refrigerate, and therefore, temperature of boiler is lower.If need be through refrigeration, the temperature of pot body generally be exactly room temperature.
3), seasonal environment temperature difference main cause is along with the seasonal variations indoor temperature also changes thereupon.Stove and accessory startup initial temperature and coefficient of heat transfer, stove and accessory and pot body etc. exist temperature deviation under the room temperature environment temperature effect of Various Seasonal.
4), the real time temperature of electrical heating stove and accessory is related to stove and accessory and starts initial temperature and coefficient of heat transfer thereof, mainly be reflected in front course meat and fish dishes culinary art finish after the uncertainty of its furnace surface temperature of course meat and fish dishes under the correspondence.
2. soup stock viscosity deviation
Viscosity has influence on thermal conductivity factor, finally can be converted into the deviation of kettle temperature.
3. the deviation of pot cover seal degree causes the variation of pot interior water content
Seal degree is related to coefficient of heat transfer, finally can be converted into the deviation of kettle temperature.
4. the deviation that produces in the dish layoutprocedure
Mainly be the heat demand difference that the deviation of food materials input amount causes, finally can be converted into the deviation of kettle temperature.
5. there is the deviation of processing technology in pot body itself
Heat generation speed and conduction deviation finally can be converted into the deviation of kettle temperature.
6. electrical heating stove and accessory self power deviation
The difference of electrical heating stove and accessory components and parts causes Difference of Output Power, finally can be converted into the deviation of kettle temperature; The aging power output deviation that also can cause of electrical heating stove and accessory.
7. the deviation of operating voltage, electric current is reflected as the power deviation of electrical heating stove and accessory
Electrical heating stove and accessory Difference of Output Power finally can be converted into the deviation of kettle temperature.
In above-mentioned deviation, because raw material condiment and the dish for preparing and pot body are states such as refrigerating, thaw in practice, with all kinds of food materials and vessel under the normal temperature be different to heat demand, so before formulation dish cooking technology begins, the dish after the refrigeration and a pot body thereof are tested, compare with the test gained technique under the normal temperature, obtain error parameter, determine again set temperature after obtaining probe temperature, improve power to system's headspace of rectifying a deviation;
For above-mentioned deviation, the different initial temperature (t) of actual measurement is related to the actual culinary art effect of dish.In summer, also involve the problem that can apparatus overheat start.Remedy in order to make dish when culinary art electrical heating stove and accessory start smoothly and carry out energy, when starting, need insert following two steps:
A) when design construction vegetable manufacture craft, no maximum improves the temperature requirements (being that T is much larger than t) of first technique, so that no matter how high the real time temperature of sensor is, lower one technological process can start operation, then in process time, heat is based on hot transfer principle balance voluntarily between stove and accessory and pot body.
B) for guaranteeing that the actual culinary art of vegetable effect error is in controlled range, control module is monitored compensation to the vegetable fabrication processing, the real time temperature and the normal temperature (can arrange) that are about to temperature sensor compare, delimit the overtemperature scope according to experimental data, in the time of in scope the vegetable of cooking is carried out proportional compensation or the fixed value compensation of manufacture craft time, real time temperature such as sensor is higher or lower than normal temperature (can arrange) X degree, then (X/10) % of system's auto-compensation dish first paragraph process time or add X/10 second.Implementing process compensation that the rest may be inferred reduces vegetable culinary art differentiation.
Heat conduction factor and heat radiation factor are the main causes of impact culinary art effect.For kettle temperature being reached and keeping target temperature, when carrying out manufacture craft, be provided with temperature deviation digestion subprogram (submodule), so that the heat that firing equipment produces is all the time greater than because the loses heat that heat conduction factor and heat radiation factor cause, thereby eliminate to greatest extent this two error effects that factor causes.
The error of food materials input amount can affect required heat, shows as temperature contrast.Because cook utensil manufacture craft difference can cause caloric value different with heat transfer rate.Therefore in the controlled situation of target temperature, this error is also eliminated by temperature deviation digestion subprogram (submodule).
Be performed in the vegetable manufacture craft and can use more than once temperature deviation digestion subprogram (submodule) in the process to eliminate the impact that temperature deviation was brought.Dish is adjusted affirmation by electromagnetic oven on controlled basis at power corresponding to target temperature T in the section sometime, make interior dish of this time period obtain target temperature T.And can also allow and power P is set by this Temperature Control Model of U=P-k (t-T) actual power U is remained on certain specified scope, constant to keep target temperature T, like this we just formerly reach this time target temperature T with after reach and made up a controlled temperature deviation between the Different Individual of this time target temperature T and digest platform.The item that may cause as mentioned above error to produce, final common result are to make kettle temperature produce deviation.Set temperature deviation digestion subprogram (submodule) in one vegetable fabrication processing after the vegetable culinary art is finished, can be controlled at the vegetable quality error of the same race of producing in 3%.
Realize high temperature limit by the method for setting limiting value, specific as follows:
A) after observed temperature begins greater than the target temperature that arranges; the power shelves progressively lower category according to the relation with (t-T); then no longer carry out and lower category when the power shelves drop to minimum; if this moment, temperature value still continued to rise; rise to (usually come across do pot is dried fries in shallow oil dried drying when the state such as stir-frying before stewing) limiting value (overtemperature protection value), then electrical heating controllable temperature stove and accessory execution halt command of setting more.
B) eliminate (being that food materials pan temperature is down in the controlled range) when high temperature limit, stove and accessory starts, and the starting power gear is according to constantly adjusting with the relation of (t-T).
