The invention provides diacylglycerol-rich grease variable-temperature deodorization and deacidification equipment and a diacylglycerol-rich grease variable-temperature deodorization and deacidification method. The equipment comprises a tower body, and a low-temperature section, a heat exchange section and a high-temperature section are sequentially arranged in the tower body from bottom to top; the low-temperature section comprises a low-temperature packing layer and multiple layers of heating assemblies which are sequentially arranged from top to bottom, an oil inlet assembly is arranged above the low-temperature packing layer, a conical dispersion plate is arranged below the low-temperature packing layer, and the multiple layers of heating assemblies comprise large heating discs and small heating discs which are sequentially and alternately arranged from top to bottom; the edge of the small heating disc and the inner wall of the tower body are provided with an annular liquid outlet channel; the edge of the large heating disc is hermetically fixed with the inner wall of the tower body, a liquid outlet hole is formed in the middle of the large heating disc, and a low-temperature direct gas pipeline is fixed at the lower end of the large heating disc and is provided with a downward gas outlet hole. The high-temperature section, the heat exchange section and the low-temperature section are integrated in the same tower body, the occupied area is reduced, meanwhile, the multiple layers of heating assemblies of the low-temperature section are arranged, low-temperature long-time heating of oil liquid is achieved, and the deacidification and deodorization effects are achieved.

The application discloses a cooking utensil, a heating control method thereof, a storage medium and a controller, wherein the cooking utensil comprises a pot body and a heating component, the heating component is adapted to heat the pot body, and the heating power of the heating component is adjustable; the method comprises the following steps: in response to a starting instruction of the cooking utensil, the heating component is controlled to work, and the temperature of the pot body is acquired; in the case that the temperature of the pot body is less than or equal to a preset temperature threshold, the heating power of the heating component is adjusted, so that the heating component works at a first preset heating power; in the case that the temperature of the pot body is greater than or equal to a first preset temperature, the heating component is controlled to heat at a second preset heating power, so that the temperature of the pot body is maintained above the first preset temperature; in the case that the temperature of the pot body is greater than a second preset temperature, the heating component is adjusted in power, so that the heating component heats at a third preset heating power. The method realizes low-temperature long-time heating cooking.
