Pre-cooking machine capable of avoiding steam scald

The invention discloses a pre-cooking machine capable of avoiding steam scald, and relates to the technical field of pre-cooking machines.The pre-cooking machine comprises a pre-cooking machine body, a food storage box is rotationally connected to the pre-cooking machine body, a transverse plate is fixedly connected to the upper end of the food storage box, vertical plates are symmetrically and fixedly connected to the upper end of the food storage box, and penetrating grooves are formed in the vertical plates; clamping holes are formed in the opposite sides of the vertical plates at equal intervals, so that in the process that food in the food storage box is poured out in a rotating mode, the gravity block is always kept vertically downward under the influence of gravity, a steam exhaust opening of the steam exhaust pipe is driven to be upward all the time, and therefore when the food in the food storage box is poured out, generated steam can still be exhausted to the upper portion; by means of the food stor
