Description
Technical field
The present invention relates to a kind of cooker, particularly a kind of low baking temperature heating and energy saving digester.
Background technology
Pressure cooker has become as one of indispensable cooker of family of China hundreds of millions, is averagely had with family of China 3.7 hundred million
Calculate flatly, that is, have nearly 400,000,000 mouthfuls of pressure cookers in routine use.Conventional pressure pot typically has rotation between pot and pot cover
Turn embedded structure, the pressure limiting valve of high steam of releasing or release valve arrangement etc..This pressure cooker needs someone to nurse,
Close thermal source by artificial means in time.Its pressure-relief valve also can send ear-piercing airflow noise, and a large amount of pressure of injection is high
Warm steam or liquid.In the case of pressure-relief valve airway blockage, conventional high-tension pot can occur the defects such as blast.
It is that utilization efficiency of heat energy is low that conventional pressure pot also has another prominent defect, according to pressure cooker work process
In heat transfer form, heated by pressure cooker process is, combustion gas is passed through gas-cooker and heated to the bottom of a pan, and heat is passed through in the bottom of a pan
Conductive form transfers heat to the bottom of a pan and pot wall；There is heat with the bottom of a pan and pot wall inner surface in the food in pot
Conduction, the food in pot is heated and boils, and meanwhile, with surrounding air, convection current occurs outside the pot wall of pot
Heat exchange, and along with radiation heat release.
Food-steaming pot steaming and decocting analysis shows, food is in pot by life to ripe time length and kettle temperature and pressure
The size of power pot pressure is relevant.The size of pressure cooker pressure, is the face of the weight by pressure limiting valve weight and valve seat orifice
Determining, most of model weights nearly weigh 160g～190g, valve seat bore dia about 4mm to long-pending size,
Pressure in pressure cooker (a diameter of 18cm～26cm) is 0.13MPa～0.15MPa, now in pressure cooker
Temperature is 125 DEG C～130 DEG C.In general, pressure is bigger, the higher food of temperature is ripe must be faster, but simultaneously
Non-linear relation, this is because some food absorbs moisture in digestion process and absorbs heat, some food is then inhaled
Receive heat and separate out moisture, its essence of absorption heat of food is diabatic process, separate out moisture or absorption moisture is
Mass transport process, also includes the phase transformation of water.Heat transfer is determined by the temperature difference, mass transfer then height, the pressure size with temperature
Interact, so, not kettle temperature is higher, pressure bigger food maturation speed is faster.Either meat
Class or the processing of plant food-steaming, when kettle temperature is in saturation temperature, that is, 125 DEG C～130 DEG C are afterwards,
In pot, the temperature retention time length required for maturation of food, is determined by food mass transfer rate, the process nature of mass transfer,
It is chemical reaction process under physical condition for the food, in this physical and chemical process, the main physics of food becomes
Change have dispersion, fusing, solidification, volatilization, condensation etc., chemical change have degeneration, hydrolysis, decomposition, polymerization,
Oxidation, esterification etc., the process of said process i.e. food maturation.The length of temperature retention time determines cooking stove combustion
The time of burning heating, thermal power needed for holding stage, the heat needing depending on maintenance temperature in pot and pot wall
Heat dissipation capacity, maintains the heat that temperature needs in pot and pressure cooker releases that steam in pot is relevant, and pressure cooker is released in pot
Steam is more, and heat consumption is more.Analysis shows, maintain temperature stage in pot, pressure cooker is released, and pot is interior to be steamed
Vapour belongs to more than needed and releases that is to say, that the pressure in pressure cooker is in saturation between 0.13MPa～0.15MPa
Pressure, belongs to unnecessary heating higher than steam in this pressure releasing pot.Therefore, it can identification steam of releasing to belong to
Heating more than needed, this waste of steam fuel of releasing more than needed.This being wasted in is cooked extremely using pressure cooker steaming and decocting
Generally.Analysis pressure cooker thermodynamic process, seeks to realize energy-conservation by thermodynamics measure, generally makes for China
With the life style of pressure cooker steaming and decocting culinary art, there is important energy-saving and emission-reduction meaning.
The heat dissipation analysis of pressure cooker：
After cooking gas heating, pressure cooker becomes heat transfer alms giver to pressure cooker, and inside pressure cooker, cooking is
For acceptor, because pressure outer wall of wall occurs phenomenon of Heat with surrounding air simultaneously, pressure cooker outside air be also by

Above-mentioned analysis shows, existing pressure cooker steaming and decocting cooking method, most of heats are radiated by pot outer wall
Consume, energy utilization rate is almost only capable of reaching 1/3.
Most of pressure cookers in the market, the pot wall of pot is identical with the bottom of a pan material, this generates one and asks
Topic, pressure cooker is in heating process it is desirable to the heat conductivity in the bottom of a pan is the bigger the better；And pass through to reduce heat
The pot wall of pot does reactive power consumption to function of environment heat emission it would be desirable that the pot wall heat conductivity of pot is the smaller the better.Solve
The method of this problem is the pot wall of the bottom of a pan and pot, respectively by heat conduction requirement adopt different materials manufacture it is clear that this
The structure manufacture difficulty of sample is very big, and cost can be very high, and manufacturing process also is difficult to realize.
Content of the invention

The good effect of low baking temperature heating and energy saving digester
It is documented, gas-cooker thermic load >=4.2kW【Zhang Huaqing, energy saving gas cooker ten thousand and is born
Averagely save gas, China Economic Herald/2006 year/April/18 day/the B02 version than general gas stove】.According to
The calorific value of natural gas is 8000～8500kcal, takes calorific value to be 8500kcal, then stove ocellate maximum air consumption
For the gas-cooker of 4.3kW thermic load, gas consumption reaches 0.435m per hour3.According to existing cooking gas consumption
0.435m3/ hour, family cooks every time one hour and calculates, after low baking temperature heating and energy saving digester technology,
Actual open amount is only 1/3 flow rate calculation of existing pressure cooker, and there are nearly 400,000,000 families, 400,000,000 families in China
In, there is 50% family to use gas stove heated pressure pot steaming and decocting to cook, conventional pressure pot is：0.435m3×1
(hour/sky) × 2 (hundred million pressure cookers)=0.87 billion cubic meter combustion gas (daily), whole nation whole year consumption of resident
Combustion gas 317.55 hundred million m3(365 days), this estimation is announced with rich combustion net；Prediction prediction resident in 2015
Demand is sufficiently close to for 325 billion cubic meters【Www.gasshow.com August in 2015 7 days】.Due to
The provision for thermal insulation of low baking temperature heating and energy saving digester pot body, cooking gas normal flow only used by low baking temperature heating and energy saving digester
Amount 1/3 can reach the effect of conventional pressure pot cooking, calculated according to 1 year actually used 365 days, can
To save combustion gas 211.7 hundred million m3, quite reduce by 4,000,000,000 m3Carbon emission.Compared with conventional pressure pot, need not pot
Rotate embedded structure between lid, operation is simpler, the Weight type pressure limiting valve of high steam of need not releasing unload laminated structure,
Safer.When in low baking temperature heating and energy saving digester, the steam pressure of pot rises, the pressure of low baking temperature heating and energy saving digester
Power governor motion, glue ring is floated the steam pressure of pot in release, this mechanism's ventilation face by the steam pressure of interior pot
Long-pending big, air-flow passes through also to send ear-piercing airflow noise, will not spray high-temperature steam or liquid, eliminate
There is the danger of blast in conventional pressure pot pressure-relief valve airway blockage.
