The invention discloses automatic heating beverage production device which structurally comprises a motor, a motor supporting rod, a tank body, a base and supporting legs. The bottom end of the motoris welded with the top end of the motor supporting rod, the motor supporting rod is arranged at the top end of the tank body, the motor supporting rod and the tank body form an integral structure. Byimproving a feeding structure of the device, when the device is used, the liquid level in the tank body can be detected through a liquid level detection mechanism, when the specified liquid level is reached, a valve is automatically closed to stop liquid feeding, and the phenomenon is prevented that excessive feeding of a feeding device exceeds the processing limit of device to affect the qualityof produced beverages. In addition, the feeding flow is detected through a liquid adding driving mechanism, so that enzyme is added according to the feeding flow for fermentation, the enzyme in a rawmaterial is stabilized, and the phenomenon is avoided that the enzyme is excessive or insufficient to affect the quality of produced beverages.
