From the internal diagram, we can see that the boiler part of Aurora is very large, and the internal structure has been adjusted to remove the automatic water feeding system. Instead of adding a temperature probe at the top of the boiler, a vacuum valve has been added, which makes preheating simple and fast. The heat exchange pipeline can be seen below, and the direction is very clear. Cold water enters the heat exchange module from the left and then flows out from the right. The hot water from the pipe connected to the cooking head will boil the coffee powder in the powder bowl.

E61 another function praised by the world is the automatic prepreg function. The hot water pressure of making espresso is equivalent to 8: 10 atmospheric pressure, and if the water under such high pressure is applied to the surface of the coffee cake at once, it is not very beneficial for coffee extraction, so engineers who design and make coffee machines should try to avoid it. On E61, an expansion cavity (cavity 4) is designed to slow down the pressure establishment process. In addition, hot water from the boiler through the inlet to cavity 1, cavity 2, cavity 3 and then to the water distribution network, it has to go through tortuous and narrow pipes, which play a good role in limiting current. Therefore, for the E61 head, the hot water pressure is slowly established, and this pressure establishment process is called preleaching.

Aurora Europa, also known as Termozona, was one of the few real heat-exchange single-ended espresso machines in the early years. The year of manufacture is the 1970s. The reason why it is called single-head is that many manufacturers use dipper tube design when making single-head machines, while multi-head machines use heat exchange. The Aurora is a real single-ended coffee machine with a large boiler, and the power consumption is not high. Most of the originals in the Aurora machine are unique, unlike other coffee machines.
