Description

A kind of pot

Technical field

The utility model relates to a kind of cooking apparatus, relate in particular to a kind of water vapour that utilizes as the culinary art thermal source, and steam temperature can regulate, and can realize utilizing medium to carry out the pot of food cooking.

Background technology

Culinary art is that food material is carried out to hot-working, and the raw food Raw material processing is become to delicatessen.In cooking process, normally utilize the vessel of food container (such as the medium pot) (such as water, oil, air etc.) or vessel conduction heat itself, thereby the purpose that realization is heated food.At present, cooking the thermal source often adopted is combustion gas and electricity.Such as: adopt electrically heated electric cooker, electromagnetic oven etc., and the gas furnace of employing open firing etc.Although the process to culinary art while adopting electricity or combustion gas as the thermal source of culinary art brings great convenience, but in electric spark or naked light are had to the environment of prohibiting (as outdoor bad borders such as the operating modes such as mine and forests), adopt electricity or the combustion gas may be explosion caused as the cooking apparatus of culinary art thermal source and the major disaster such as fire, cause the loss of personnel and property.In addition, in the wild or in travelling way, often can't obtain electricity or combustion gas, therefore also need not adopt electricity or the combustion gas cooking apparatus as the culinary art thermal source.

Nowadays, a kind of cooking container of chemical energy as the culinary art thermal source that adopt arranged in existing cooking apparatus.Its working method is, outside the vessel of food container, place a reaction vessel, wherein place from adding fever bag (being called for short generates heat wraps or the reaction material bag), utilize the heat discharged in the water generates chemical reaction process in heating bag and reaction vessel as the thermal source of cooking.Adopt this kind cooking apparatus can make water heating or the boiling in the vessel of food container, thereby the cooking method such as realize stewing, boiling.Although existing employing chemical energy has realized not producing the cooking function of spark and naked light as the cooking apparatus of culinary art thermal source, the cooking method such as also can realize stewing, boil, but because the temperature of water vapour under an atmospheric pressure is up to 100 ℃, the maximum temperature of the heat food that above-mentioned cooking apparatus can provide is no more than 100 ℃.Even existing similar cooking apparatus has adopted relief valve to improve the pressure of saturated water vapour in the reaction vessel, but because its main purpose is to accelerate the boiling speed of the water in the vessel of food container, to realize shortening the function of food cooking time, therefore, the force value in the reaction vessel in similar cooking apparatus smaller (generally in 1.2 atmospheric pressure left and right).According to the temperature of water vapour and the relation between its saturated vapor pressure, learn, the pressure in reaction vessel has determined the temperature of water vapour, thereby has also determined the temperature of the vessel of food container and medium wherein.Thus, in similar cooking apparatus the vessel of food container and wherein for the maximum temperature of the medium of cooking food substantially at 100～105 ℃.Be limited by temperature, similar cooking apparatus can only adopt the medium of water as culinary art, the cooking method such as can only realize stewing, boil.And fry, explode, decoct, (for example: temperature wet goods) is all far above 100 ℃ for the medium in the vessel of the cooking method requirement food container such as Bao, is baked, roasting.For example: during frying food, the oil temperature needed is generally at 160 ℃～170 ℃, and the temperature of fried food is generally at 120 ℃～130 ℃.Adopt existing similar cooking ware can't realize frying, explode, decoct, the cooking method such as Bao, is baked, roasting, its function as cooking ware is limited by very large.

In addition, in existing similar cooking ware, utilize in the process that heat energy that reaction material bag and water generation chemical reaction produce cooks as thermal source, when reaction material bag and water reacted, its chemical reaction rate was, with the temperature of the residing environment of material bag, substantial connection is arranged.According to Arrhenius (Arrhenius) formula:

k＝k ₀exp(-E _a/RT)

Wherein, k is speed constant, and R is molar gas constant, and T is thermodynamic temperature, E _aFor apparent activation energy, k ₀For pre-exponential factor (also claiming frequency factor).Due to what in material bag, occur, be the solid-liquid phase reaction, according to the concentration of the concentration of solid-state reactants in heterogeneous reaction and immiscible neat liquid reactant not the writing rate equation learn, the reaction rate of the reaction occurred in the material bag equals reaction rate constant k.

According to Arrhenius (Arrhenius) formula, learn, when other conditions are constant, the temperature of the reaction environment of living in that raises, chemical reaction generally all will be accelerated.Measuring, 10 ℃ of the every risings of temperature, reaction rate increases to original 2～4 times usually.Due to the force value in existing similar cooking ware reaction vessel smaller (generally in 1.2 atmospheric pressure left and right), variation of ambient temperature during the material packet response can only be increased to 105 ℃ at most from 100 ℃ under an atmospheric pressure, therefore the variation of temperature very little (in 5 ℃), can think the chemical reaction rate substantially constant.And after the environment temperature when the pressure by remarkable change material bag environment of living in is expected packet response to significantly improve, the chemical reaction rate of material bag will have significant change.For example, when the pressure by reaction vessel is increased to approximately 5 atmospheric pressure by 1.2 atmospheric pressure, temperature in reaction vessel will be increased to approximately 155 ℃ by 105 ℃, because temperature has raise approximately 50 ℃, the chemical reaction rate of material bag will increase to original 10～20 times, thereby be conducive to expect to wrap the quick generation of reacting with water, the i.e. rapid release of heat, temperature with the vessel that make quickly food container and medium wherein (as, oil) reaches the temperature value that culinary art needs.

In addition, existing similar cooking ware, because it has adopted the relief valve of fixation pressure, the maximum pressure value that in its reaction vessel, water vapour produces (as, 1.2 atmospheric pressure) fix, make the pressure range (0～0.2 atmospheric pressure) of water vapour in reaction vessel very little, the vessel of food container and the range of temperature of medium thereof be accordingly less (0～0.5 ℃) also.Can't require to select different cooking temps according to the difference culinary art.

In addition, existing Domestic pressure cooking ware, in the cooking process of food, food to be cooked is in the pressure atmosphere.As, Domestic pressure cooker is in cooking process, and the residing pressure atmosphere of food is 1.2～1.8 atmospheric pressure.Well-knownly be, the food cooked in the high pressure atmosphere, the nutritional labeling of its food, mouthfeel etc. all are worse than under normal pressure (1 atmospheric pressure) condition.Therefore, existing employing chemical energy is as the cooking container of culinary art thermal source, even food that will be to be cooked is in the pressure atmosphere, the mouthfeel of the food that it cooks and the reservation of nutritional labeling etc. are the food not as cooking under condition of normal pressure also.

For the problems referred to above, the utility model has designed a kind of naked light that do not produce, utilize heating bag and water exothermic heat of reaction, by changing the force value in reaction vessel, both can realize stewing, boiled, stewed, fried, exploded, decocted, the multiple cooking methods such as Bao, is baked, roasting, can control again stir-fry, explode, the oil temperature while decocting, and can not produce the oil smoke of infringement health.Have boundless application prospect and commercial promise.
