Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the application provides a method for making a heating cup body. The welding medium will not melt when the non-stick layer is sintered, so as to ensure that the heating device is firmly welded on the metal inner cup and prevent the occurrence of welding of the heating device. Problems such as defective or falling off of the heating device after welding; moreover, elements such as manganese and chromium contained in stainless steel will not penetrate into the slurry, effectively ensuring the food safety of the slurry

Abstract

The invention provides a heating cup body manufacturing method. The heating cup body manufacturing method comprises the steps that a heating device is welded to the outer surface of a metal inner cupthrough a welding medium; and a non-stick layer is sintered onto the inner surface of the metal inner cup. The melting point of the heating device and the melting point of the metal inner cup are higher than the melting point of the welding medium, and the melting point of the welding medium is higher than the sintering temperature of the non-stick layer. When the non-stick layer is sintered ontoa heating cup body, the welding medium is not melted, thus, it is ensured that the heating device is firmly welded to the metal inner cup, and the problem that heating device welding is poor or the heating device is disengaged after welding is solved; and in addition, manganese, chromium and other elements contained in stainless steel do not seep into slurry, and the edible safety of the slurry iseffectively ensured.

Description

technical field [0001] The application relates to the field of food processing, in particular to a method for making a heating cup. Background technique [0002] At present, the metal inner cup of the heating cup of the household soybean milk machine is generally made of stainless steel, and the outer bottom surface or the outer surface of the metal inner cup is welded with aluminum-silicon flux (that is, one of the welding media) with an aluminum heating tube. However, elements such as manganese and chromium contained in stainless steel will seep into the slurry during the pulping process, and drinking slurry containing elements such as manganese and chromium for a long time is not conducive to human health. [0003] The existing solution is: sinter a non-stick layer on the inner surface of the metal inner cup to prevent elements such as manganese and chromium from penetrating into the slurry, but the sintering temperature of the non-stick layer is relatively high (the sint...
