[0002] A steam coffee machine is a device that uses the principle of steam to make coffee. It uses steam to pass directly through the ground coffee powder of deeply roasted coffee beans, and extracts coffee through high-temperature steam.

[0003] The basic principle of a steam coffee machine is to generate steam by heating water, and then introduce the steam into a filter basket filled with coffee powder. When the steam passes through the coffee powder, it will exert a certain pressure, dissolving the coffee's aroma, taste, pigment and other extracts from the coffee powder, and finally flow out through the outlet to form coffee.
