Coffee maker silicone tubing has: cold and high temperature resistance, weak acid and alkali resistance, harmless, non-toxic and tasteless; high transparency, high elasticity, strong UV resistance; good elasticity, resistance to kinking and no deformation, softness, chemical stability, physiological inertness, and human body Non-toxic, non-irritating, hydrophobic, breathable, excellent resilience, permanent non-deformation, etc., can be used at -50 to 250 degrees, it is the best choice for connecting pipes for coffee machines.

 

Coffee machine performance principle:
Since LuigiBezzera launched the first commercial coffee machine with steam pressure in 1901, whether it is PavoniGaggia or other machines that use steam or pistons as pressure, there is only one boiler: the bottom of the boiler is hot water for brewing coffee, and the top of the boiler provides steam. But in order to produce steam, the entire boiler must be heated to boiling, so that the hot water close to the boiling point burns the coffee powder, loses the aromatic oils hidden in the coffee powder, and extracts more bitter coffee.

Since the water used for brewing coffee is heated in a large boiler, the water will become stale if left in the boiler for too long, and the temperature difference of the hot water will increase due to the use of steam. The temperature difference of the hot water for making coffee. In order to improve the temperature difference, Ernesto Valente changed the heating method of the water used to brew coffee in the world's first FAEMAE61 with a pump as a pressure source in 1960, so that the water used for brewing coffee does not directly contact the heat source, but Use a method similar to water heating.

The FAEMAE61 boiler (hereinafter referred to as the outer boiler) is connected by a silicone tube in the middle, which uses a pump to introduce fresh cold water into the internal curved pipeline. When the pump pushes fresh cold water through this silicone tube, the cold water will become hot due to the hot water in the outer boiler, but there is a food grade silicone tubing wrapped around it, so the fresh water will not be the same as the hot water in the outer boiler. When contacted, the internal water pipe is made into a curved shape, so that the cold water has enough time to contact the outer boiler and become the hot water temperature just suitable for brewing coffee.
