Description
Technical field
The utility model relates to a kind of cooker.
Background technology
Traditional non-stick pan uses fluorinated polymer to form the thin layer of not sticky food at the inner surface that pot body is recessed.The fluorinated polymer that pan the most often uses is Teflon.The not sticky characteristic of Teflon is because of its low-surface-energy, but this also can cause it not strong to the adhesion of pot body.Teflon attachment forms thin film on the metal surface, and this film manifests a large amount of pores under the microscope.When in cooking process, salinity, by these pores, is easy to react with metal, particularly iron, causes the Teflon of inner surface of pot body to protrude bulge, come off.Although the mode that this chemistry does not glue has original not sticky effect, the problem that comes off of teflon coatings, and when temperature of boiler is greater than 200 DEG C, Teflon starts the problem of decomposing harmful substances, the method and structure causing people to pursue pan physics not gluing.
The principle that pan physics does not glue makes foodstuff surface uniform carburized in culinary art, because the surface energy of the food after carbonization reduces, is easily separated with pan surface, thus the food entirety after surface uniform carbonization is easily separated with pan.But in culinary art, often occur that food is just stirred food by the area of heating surface is not yet uniform carburized, at this moment food and pan just there will be the sticky glutinous phenomenon in local.Further, it is found that, when the inner surface that pot body is recessed is covered with the dot matrix of salient point formation, with the surface contact of the upper surface of each salient point and food during culinary art, namely the contact surface that the recessed inner surface of pot body directly contacts with food is reduced, for local location food not having on these contact surfaces carbonization simultaneously, process due to carbonization can cause the sclerosis of foodstuff surface to reduce distortion, at this moment the gap of foodstuff surface due to distortion formation will freely be filled by the grease heated in salient point peripheral recesses place, the carbonization at the non-carbonization position of further quickening foodstuff surface, can effectively promote the uniform carburized of foodstuff surface.
Stainless pot for stir-frying is in the market in order to obtain good thermal conductivity and the heating of electromagnetic stove, all adopt " interlayer steel " material, the ferromagnetism stainless steel of the nonferromagnetic stainless steel of the interior surface layers of this material to be thickness be 0.5mm, outer surface layer to be thickness be 0.5mm, and the interlayer of centre adopts aluminium alloy (general outer surface layer is the interlayer of SUS 430 ferromagnetism stainless steel-centre be 1007Al aluminium alloy-interior surface layers be SUS 304 nonferromagnetic stainless steel).This Stainless pot for stir-frying, because the surface great majority of interior surface layers adopt conventional rubbing down process, non-adhesion behavior is not strong.
The physics release treatment of the inner surface that existing Stainless pot for stir-frying pot body is recessed, impact style is mainly adopted to make the lattice-like pattern of indentations of honeycomb pattern, this mode is because technical reason cannot form the high low head that in dot matrix, each hexagon salient point periphery top and bottom are vertical, and along with the process of punching press, the upper surface of hexagon salient point can form an arc surface, compares perfect condition and increases the contact surface with food.Another problem is that punching press hexagon salient point can only split the recessed inner surface of pot body with thinner straight line, also the dot matrix realizing reduced size hexagon salient point is difficult to, this not only large area cannot reduce the direct contact surface of pan and food, also destroy the Density Distribution of inner aluminium alloy layer, hexagon salient point also brings the trouble in cleaning simultaneously.Therefore practical effect is not good.
Utility model content
The utility model aims to provide the not sticky frying pan of a kind of stainless steel, and it is easy to produce and has not sticky effect preferably.
The technical solution of the utility model is: the not sticky frying pan of a kind of stainless steel, and recessed pot body has interior surface layers and the stainless outer surface layer of magnetic of non-magnetic stainless steel, and the intermediate course of aluminium alloy; The surface bottom portion of inner surface of pot body layer is covered with netted groove, and the ledge in this groove is the dot matrix of cylindrical salient point composition; The end face of each cylindrical salient point is plane; The degree of depth of this groove is 0.1-0.2mm, and the diameter of each cylindrical salient point is 2.0-3.0mm, and the area of this bottom portion of groove is 3-3.5 times of all cylindrical salient point top surface area summations.
The non-caked structure of physics of the present utility model adopts the combination of the dot matrix of meshed grooves and cylindrical salient point, no matter slice in any direction shovels to cylindrical salient point, food all can be separated from 1 point with the contact site of cylindrical salient point by it, thus promotes that food is all easy to be separated with pot body in any direction.And the orthohexagonal salient point of prior art, then occur the phenomenon that food is separated from a straight line with the contact site of this salient point by slice sometimes, this can cause being separated not easily thorough, there is the problem of adhesion.Moreover adopting periphery there is no the cylindrical salient point of corner angle, cleaning operation is not by the restriction in direction, and the dirt in groove easily cleans up, and cleaning process follows the stainless steel pan of cleaning common plane equally light substantially.The end face of each cylindrical salient point is plane but not arc surface, and the contact surface of food and pot body is close to perfect condition; Be conducive to improving non-adhesion behavior.Because food is on the dot matrix of cylindrical salient point, slightly sagging phenomenon can be produced by recess between cylindrical salient point, the contact angle of food and pot body is no longer 180 ゜, but form the contact angle being less than 90 ゜, greatly reduce and be separated food and the power required for pan, more easily realize being separated of food and pan.Can ensure to form the microscopic contact angle being easy to be separated pot between body with food so do like this, be conducive to food and be separated with pot body under the effect of slice.Because pot body circular " interlayer steel " dull and stereotyped punching stretch is formed, the degree of depth of groove is decided to be 0.1-0.2mm, the diameter of each cylindrical salient point is decided to be 2.0-3.0mm, not only can make the not viscosity that pot body has had, and electricity consumption caustic solution machined " interlayer steel " flat board of the dot matrix of above-mentioned meshed grooves and cylindrical salient point in advance, there will not be in follow-up punching stretch forming manufacturing procedure and break, and also there will not be and break when the pot body daily cooperation stainless steel slice produced uses.When propagandizing industry owing to decocting, grease is full of in groove, these greases can heat equably to the foodstuff surface that it contacts, the area of regulation bottom portion of groove is 3-3.5 times of all cylindrical salient point top surface area summations, this ratio area that too conference directly contacts with food because of bottom surface strengthens, and the area causing food to be heated uneven strengthens, and this ratio is too little, can strengthen the area that food directly contacts with pot body, aggravation is heated uneven, also increases the difficulty in cleaning simultaneously.In the ratio range more than specified, food can be realized and the minimum direct contact surface being about 24% of pot body amasss, be about at most the suspension grease heating surface of 76%.During culinary art, grease and the heat conduction of pot body to food will be more even, thus impel food by the area of heating surface evenly carbonization.
Implement in structure preferred: the degree of depth of described groove is 0.15mm, and the diameter of described cylindrical salient point is 2.40mm.
Experiment proves, adopts the pot body non-adhesion behavior of above parameter best, and in punching stretch forming processing, resistance to rupture is good, long service life.
And then: between adjacent two described cylindrical salient points of same a line, the center of circle spacing of horizontal direction is 4.40mm; Vertical direction center of circle spacing between every a line circular cylindrical projection point with a cylindrical salient point of adjacent lines is 3.81mm and in the cylindrical salient point of this row, each cylindrical salient point moves horizontally 2.20mm relative to cylindrical salient point adjacent in the cylindrical salient point of these adjacent lines respectively to the right side; Vertical direction center of circle spacing between every a line circular cylindrical projection point and the cylindrical salient point of another adjacent lines is 4.17mm, and in the cylindrical salient point of this row, each cylindrical salient point moves horizontally 1.40mm relative to cylindrical salient point adjacent in the cylindrical salient point of these adjacent lines respectively to the right side.
In meshed grooves, each cylindrical salient point adopts the lattice structure of above-mentioned non complete symmetry form, the front end of slice in any direction all can not snap in the depressed area of meshed grooves, thus the interference that when can avoid using, groove moves to slice, ensure the fluency that slice uses.
The not sticky frying pan of the utility model stainless steel, adopts galvano-cautery technology to form the dot matrix of the cylindrical salient point that conventional punch technology can not be formed in the interior surface layers of " interlayer steel ", and be not only easy to produce and have not sticky effect preferably, its product is also convenient to cleaning.Because galvano-cautery technology can not destroy the structure of aluminium alloy in the middle of " interlayer steel ", and accurately can control the size of each salient point, so the utility model can structurally realize physics non-adhesion behavior to greatest extent, there is value and the prospect of popularization.
Because freezing sliced meat are rich in moisture, in fry process, its moisture oozes out the carbonization that can affect sliced meat surface and the sliced meat surface of this non-carbonization is easy to be bonded at pan inner surface, is very large test to the non-adhesion behavior of pan.So we decoct the contrast test of freezing sliced meat with the not sticky frying pan of the utility model stainless steel and conventional Stainless pot for stir-frying.
