At present, there are many kinds of commercial coffee machines on the market, and many people still don't understand them. Let's learn about the types of commercial coffee machines.

1, American (traditional trickling filter) coffee machine

As the name implies, it is drip-filtering coffee brewing, which generally consists of a funnel-shaped container at the upper part and a coffee pot at the lower part. When in use, the ground coffee beans are put into the funnel-shaped container on the upper layer, and the cold water in the water tank will drop into the container containing coffee powder after heating, and then drop into the coffee pot below after soaking and extracting.

2. Italian (high-pressure pump) coffee machine

Italian coffee machine is named after its Italian origin. It uses high-pressure hot water to brew espresso, and high-pressure steam and water are mixed and quickly extracted by coffee powder. Italian coffee machine is generally divided into traditional boiler type and cutting-edge heating block type in heating. The traditional boiler type has stable water temperature and high extraction quality, but its manufacturing cost is high, so it belongs to high-end coffee machine. Cutting-edge heating block technology, with low cost, good controllability and relatively good product quality, is common in low-end and fully automatic toy italian coffee machine.

3. Capsule coffee machine

The new coffee machine that has caught fire in recent years is specially designed for lazy people who still have some requirements on quality. Strictly speaking, it can also be regarded as a kind of italian coffee machine. Simple and rude operation: just buy capsules of various flavors provided by machines and manufacturers. When in use, put the capsule into the machine and press the switch to get a cup of medium-to-high quality espresso. Friends who love espresso very much buy it home or put it in the office.
