A method of heating and mixing contents is disclosed that combines heating and agitating of a bottle and its contents in order to achieve even warming, as well as, mixing the contents of the bottle.

The present disclosure discloses a yogurt maker and its method of use for using the same. A vertical upwardly extending mixing container protrusion is set at the bottom of the mixing container of the yogurt maker and a mixing head is detachably sleeved on the mixing container protrusion, and the rotation of the mixing head is driven by a power device so that the mixing head can mix the mixture in the mixing container well. At the same time, a temperature sensor is installed at the bottom of the mixing container to monitor the temperature of the mixing container, so as to ensure constant heat preservation conditions in different environments. The mixing device can be detached easily, which eliminates hygienic blind spots and ensures that the yogurt maker can be cleaned easily after making yogurt.

The present invention is in the field of stirring, and particularly relates to a stirring assembly including a rotary shaft and a stirring member. The stirring member is fixedly provided on the rotary shaft. The rotary shaft is provided with a first passage therein. The first passage is formed with an air inlet through one end of the rotary shaft. The stirring member is provided with a second passage therein. The second passage is formed with an air outlet through the stirring member. The second passage is connected with the first passage. In the present invention, when the rotary shaft is rotating, the external air is drawn in from the air inlet and discharged from the air outlet to make the liquid to be mixed by the stirring member with the air discharged from the air outlet.
