The invention provides a food processor, which aims at solving the problems in the prior art that the heating efficiency of the food processor is not high. The food processor comprises a body, a cover, a liner and a thick membrane heating disc, wherein the body defines a containing space; the cover is connected to the body in a pivoting manner, so that the cover is closed by moving towards the body and opened by moving away from the body; the liner is arranged in the containing space of the body; the thick membrane heating disc is fixed on the bottom of the liner. By adopting the thick film heating disc, the heat can be rapidly and completely transferred to food in the liner, and the energy utilization rate is high.
