Technical field
The present invention relates to a kind of technical field of cooking tools, relate in particular to a kind of aluminium alloy gravitational casting pressure cooker and technology thereof.
Background technology
The pressure cooker of selling circulation in the market all is flat pressure cookers, and it is aluminium, iron, stainless or the like that material has, and the aluminum pressure cooker is one of economic pan that uses in people's daily life, since flat, cause heat transfer efficiency general.
The pressure cooker that on market, circulates roughly is divided into two kinds, and a kind of is the aluminium sheet pressure cooker that aluminium sheet stretches, and another kind is stainless steel stretched Stainless steel pressure cooking-vessel.There is certain potential safety hazard in these two kinds of pressure cookers in the middle of using, pressure cooker cover has the phenomenon generation that pump leaves sometimes in the middle of the process of usefulness.
Summary of the invention
The present invention is directed to the problem that exists in the above-mentioned prior art, a kind of aluminium alloy gravitational casting pressure cooker and technology thereof are provided.Purpose is in order to provide a kind of Material Strength high, and a kind of pressure cooker safe and reliable, that the heat conduction is fast, and it can replace existing conventional pressure pot.
The technical solution adopted for the present invention to solve the technical problems is:
Aluminium alloy gravitational casting pressure cooker comprises a pot body, pot cover and handle, and pot cover is provided with safety valve and exhaust apparatus, is provided with silica gel sealing ring in the pot cover.The pot body is to be formed by the aluminium alloy gravitational casting, and correspondence is provided with handle with lock on pot body and the pot cover, and bottom of pot body is provided with groove.
The bottom thickness of described pot body is 3-15mm, and sidepiece thickness is 2-10mm.
Described exhaust apparatus is on pot cover, to be provided with the exhaust post, is arranged with exhaust cap on the exhaust post; Described exhaust cap is provided with the anti-scald bakelite of exhaust cap.
Described handle is provided with two pairs relatively, and wherein a pair of handle is that pot body upper handle with lock and corresponding with it pot body lower handle with lock constitute; Another constitutes the pot body upper handle that is provided with for pot cover and a pot body lower handle on the pot body.
Be provided with the back fore shaft in the described pot body upper handle with lock; In the fore shaft outer cover, preceding fore shaft was connected through the same handle fore shaft spring with the back fore shaft after preceding fore shaft was located at, and the structure of preceding fore shaft and back fore shaft is public affairs one mother's a form; Have hollow in the preceding fore shaft; Back fore shaft is put hollow interior connection of preceding fore shaft into handle fore shaft spring, and moving before and after two fore shafts, preceding fore shaft is an exhaust condition before the pot cover locking all the time.
The manufacturing process of aluminium alloy gravitational casting pressure cooker is to be prepared from according to the following steps:
1. dissolving: get raw material aluminium alloy aluminium ingot, dissolve, solution temperature is 730 °-750 °;
2. casting: pour the aluminium alloy solution after the dissolving in the casting mold into through gravitation casting method, foundry goods is taken out in the cooling back naturally, and foundry goods soup mouth is cut off;
3. foundry goods processing: through lathe in machining foundry goods surfaces externally and internally, make it reach smooth surface, pot cover is accurately up to standard with pot body size;
4. process of surface treatment: behind the surface degreasing, surface oxidation or hardening oxidation are handled;
5. other accessories such as handle installation, safety valve, air bleeding valve, O-ring seal promptly get.
Described aluminium alloy aluminium ingot model is A356.2.
The described the 4. step: process of surface treatment can also use following step to replace: process of surface treatment: surface degreasing, and after the blasting treatment, the inside and outside spray of pot ceramic non-stick coating.
Described the 2. step can be prepared from according to the following steps: pour the aluminium alloy solution after the dissolving in the casting mold into through the artificial gravity casting, taking-up foundry goods in cooling back cuts off foundry goods soup mouth naturally.
The characteristics of aluminium alloy gravitational casting pressure cooker of the present invention are: pot body material is an aluminium alloy casting, and intensity is high, and security is more superior than the pot that stretches; The material purity of gravitational casting is high, adopts the cast molding of special process reverse mould in the manufacture process, aluminium alloy is cast thing under the gravity effect, inject casting mold; Naturally cooling again; Therefore cast the inner molecule of thing and keep certain arrangement architecture, the heat conduction is fast, and evenly.The characteristics of gravitational casting pressure cooker are that the heat conduction is fast, and evenly, heat is evenly distributed on all sites of pot, and keeps certain temperature.The part heat that surpasses can be dispersed into the outside automatically, so temperature can not surpass 260 degree.
Space pressure is 1 air pressure in our daily life, thus the highest 100 degree of the water temperature during boiling water, but sealed water vapor during pressure cooking; So pressure rises to 2 air pressure; Water temperature when boiling reaches 120 degree, utilizes the pressure cooking of this principle, boils food with high temperature, high pressure culinary art in the short time; Food nutrition is not run off, cook out delicious food.Culinary art efficient is high, save time, the pan of energy saving and environmental protection effect.
The technology of the 70-80% of product of the present invention is accomplished through the manual process manufacturing, and therefore the class and the quality standard of pot are high.When using the culinary art of gravitational casting pressure cooker,, can boil food in the short period of time because internal temperature is high.During cook vegetables, the moisture that material itself has can heat, and prevents nutrient loss, fast heat penetration food.Steam dish, cook, fried etc., dealing with various requirements.Can prevent that food from burning, oil smoke produces, and the food of cooking out evenly boils, delicious flavour.Because of quick, uniform heat transmission function, medium and small fire also can be cooked out delicious food, is the pan of energy-conserving and environment-protective.Can replace existing conventional pressure pan, its market prospects are wide.
