Heating, evaporation and filtration, whose method is the best to separate water and starch?

Filtering is the best way to separate water from starch. Raw starch will naturally precipitate after mixing with water, and the water can be filtered out with filter paper.

Heating is actually to evaporate water. When it reaches a certain temperature, starch will be cooked into a paste. If heating is continued, starch may burn; The natural evaporation time without heating is too long.
