A high-speed rotating small metal can! There are many small holes in the waist! There is a blowtorch below to heat it! Add sugar and dissolve! And then thrown out of the hole by centrifugal force! Solidify into a floccule after encountering cold air!
The old way is to turn with your feet! It's similar to the principle of pedal sewing machine! The battery is dead!
The new model is driven by a motor! The heating is also electric!
