The process of making coffee in siphon pot is invented based on the principle of thermal expansion and cold contraction.
A brief introduction to the siphon Coffee Pot, also known as the plug Pot, it was developed by Scottish Navy engineer Robert Naiphir. It was invented in 1840. The siphon kettle is invented based on the principle of thermal expansion and cold contraction, which produces water vapor after heating with water during production, resulting in long heat and cold shrinkage. The hot water in the lower seat is pushed to the upper seat. After the lower pot cools, it produces negative pressure to suck back the water from the upper pot to get coffee.

Italian coffee machine brewing head structure-coffee machine brewing head apron replacement
Italian coffee machine brewing head structure-coffee machine brewing head apron replacement is different from ordinary brewing head. E61 is connected to the boiler (or heat exchanger) with two water pipes, the upper one is called the inlet, and the lower one is called the backwater outlet. The hot water in the boiler enters the cavity 1 from the inlet, and the flushing head is heated. After exchanging heat, the temperature of the hot water decreases, and the density of the cooled hot water increases.
