Italian Coffee Machine & usage of #160; structure Coffee Bean

Italian (high pressure pump) coffee machine:

Today, with the integration of mixed milk coffee based on Italian coffee, the market of traditional American coffee drip filter is getting smaller and smaller. From a health point of view, espresso has a low-cause characteristic that traditional coffee brewing cannot compare. In addition, it can be mixed with all kinds of syrup, cream and milk to make more acceptable coffee.

Italian coffee machine is generally divided into traditional boiler type and new heating block type from the heating mode. The traditional boiler type has been passed on because of its stable water temperature and high extraction quality. But the disadvantage is also obvious, the manufacturing cost is high, and the price of the finished coffee machine is high. Corresponding toys are the first choice of middle and high-end coffee machines. The cutting-edge heating block technology has been promoted in low-end and fully automatic and toy Italian coffee machines because of its low cost, good control and relatively good product quality.

From the use of water pump can also be a simple distinction between low-end and high-end coffee machine. Generally less than 5000 coffee machine, the use of vibration pump for extraction pressure, because the working principle of the vibration pump caused by the output pressure is not stable, so the extraction quality is poor. More than 5000 of coffee machines have rotary pumps in some mid-range models (Aibao E61). The high-end machine is the rotary pump all over the world! With the development of pressure swing extraction technology, new products such as gear pump and magnetic drive pump have jumped onto the stage. But the vast majority of the market is still occupied by vibrating pumps and rotary pumps. One of the simplest criteria for choosing a coffee machine on the market is... As long as it is a rotary pump, this machine is certainly not so bad!

From the use classification can be divided into commercial machines and household machines, commercial machines without exception have a huge boiler, most of which are 2-head or 3-head or even 4-head structure. Even single-end commercial machines mostly have more than 6L sub-mother boiler design. The household machine is either a low-end heating block or a 2L or so parent boiler. The capacity of the boiler is very small and the working quality of continuous multi-cup extraction can not be maintained. Today, with the continuous progress of manufacturers' technology, there are also some high-end household machines with the design of dual-boiler PID precise temperature control.
