The invention discloses an automatic food processor comprising an engine body, a refrigerating mechanism, a heating mechanism and a conveying mechanism; a storage chamber and a heating chamber which are separated from each other are defined in the engine body; the refrigerating mechanism is used for refrigerating the storage chamber; the heating mechanism is used for heating the heating chamber; and the conveying mechanism is used for transferring food between the storage chamber and the heating chamber. According to the automatic food processor provided by the embodiment of the invention, thefood can be stored at a low temperature in the storage chamber before waiting for heating, and the risk of food deterioration is reduced. Due to the fact that the conveying mechanism completes the transfer of the food between the storage chamber and the heating chamber, a user does not need to manually operate, and a great deal of time is saved for the user. The refrigerating mechanism and the heating mechanism are small in mutual influence, and the automatic food processor is relatively reliable, safe and energy-saving on the whole. The automatic food processor is very wide in application range.
