More preferably, the rice cooking appliance is an electric rice cooker or an electric pressure cooker.

The utility model has the advantages that:

the rice heating device comprises a heating disc, a rice vent, a rice inlet, a rice outlet, a heating disc, a heating coil, a rice outlet, a rice inlet, a rice outlet, a rice.

And secondly, the area of the contact surface is changed by changing the distance or the width of the concentric annular grooves, the original processing equipment of the heating plate can still be used, the cost and the pressure are low, the implementation is simple, and the production and installation convenience and the after-sale universality are ensured.
