[0026] As Figures 1 to 4 Indicated, a compound device of compound bottom pot, it includes upper module 1, lower module 2 and positioning ring 3.

[0027] Further, the bottom edge of the upper module 1 has a rounded portion for the working surface matching the shape of the inner cavity of the compound bottom pot, so that the two are more fitted;

[0028] The outer wall of the upper module 1 is provided with an annular groove.

[0029] Further, the lower module 2 is provided at one end of the upper module 1, and the lower module 2 is provided with a recessed die, and a protrusion is arranged in the recessed die, which is used for exhaust during compounding.

[0030] The groove 21 is used for the working surface matching the shape of the outer contour of the compound bottom sheet 6, so that the two are more fitted;

[0031] The top edge of the recessed die has a rounded portion for the working surface matching the shape of the outer contour of the compound bottom pot, and the size of the intermediate protrusion is 0.1-1mm.

[0032] Specifically, the upper module 1 and the lower module 2 are made of CrNiMo die steel.

[0033] Further, the positioning ring 3 is provided at the other end of the upper module 1, which protects the upper module 1.

[0034] The positioning ring 3 is provided with four thread holes distributed in a circle;

[0035] Specifically, the positioning ring 3 can protect the upper module 1 when it is accidentally collided or shaken and accidentally dropped.

[0036] Further, it further comprises:

[0037] A heating area is provided on the lower module 2, which is used for forming efficient heat transfer of the compound bottom pot.

[0038] Locking screws 4, four in total, are respectively threaded into four threaded holes, used for positioning and fixing between the positioning ring 3 and the upper module 1, through threaded connection, which facilitates the disassembly and assembly of the positioning ring 3.

[0039] As shown in Figures 5 to 7 A double-bottom pot made of the above device, comprising:

[0040] A pot body 5 having an open end for containing food materials and a closed end;

[0041] A double-bottom sheet 6 located at the bottom of the pot body 5 and combined therewith;

[0042] A positioning ring 7 for pre-positioning between the pot body 5 and the double-bottom sheet 6.

[0043] Further, the double-bottom sheet 6 is firmly combined with the pot body 5 through spot welding;

[0044] The double-bottom sheet 6 is made of 430 stainless steel;

[0045] The bottom of the pot body 5 is provided with a protrusion for matching the positioning ring 7, and the pot body 5 is made of ADC12 aluminum alloy.

[0046] The pot body 5, the upper module 1, the lower module 2, and the double-bottom sheet 6 adopt different materials, so their thermal expansion coefficients are different.

[0047] The working principle of the double-bottom pot and the composite device of the double-bottom pot is as follows:

[0048] From top to bottom, they are:

[0049] The upper module 1, the pot body 5, the double-bottom sheet 6, and the lower module 2;

[0050] First, the pot body 5 and the double-bottom sheet 6 are combined, the positioning ring 7 is placed at the bottom of the pot body 5, and the positioning ring 7 is matched with the protrusion at the bottom of the pot body 5, then the double-bottom sheet 6 is placed at the bottom of the pot body 5 through the fixing ring, then the positioning ring 7 is removed (the double-bottom sheet 6 is forced during this process, so that the position of the positioning ring 7 does not change during the removal of the positioning ring 7), and then the positioning ring 7 and the pot body 5 are welded together through spot welding;

[0051] After the above combination is completed, the pot body 5 is placed on the lower module 2, the open end of the pot body 5 faces upwards, and the double-bottom sheet 6 is placed in the groove 21, and there is a gap between the double-bottom sheet 6 and the lowest part of the groove 21, which is 0.1-1mm;

[0052] Then the upper module 1 is placed above the pot body 5, and the bottom of the upper module 1 abuts against the inside of the pot body 5;

[0053] The heating area on the lower module 2 is heated by heating device (such as electromagnetic coil heating), the pot body 5 and the composite bottom sheet 6 are heated by heat transfer, and the deformation composite between the pot body 5 and the composite bottom sheet 6 is caused by thermal expansion (the material between the lower module 2 and the pot body 5 and the composite bottom sheet 6 causes the expansion coefficients of the three to be different, so that the lower module 2 remains unchanged when the pot body 5 and the composite bottom sheet 6 expand and deform), in this process, the gap between the composite bottom sheet 6 and the groove 21 exhausts the air between the pot body 5, the composite bottom sheet 6 and the lower module 2 during the composite process, to avoid air retention to cause bulging between the composite bottom sheet 6 and the pot body 5;

[0054] After the composite is completed, the combined state is maintained for 60-120s for setting and cooling.
