The coffee machine allows lovers of this strong aromatic drink to enjoy it even outside the cafe. A good and properly configured vending machine can bring you a lot of profit if you install it in a place with a large flow of people.
Principles for choosing a coffee machine
Despite the obvious advantages of coffee machines, they are not often found in Russia. Many people simply do not know how to choose this device: what determines the quality of coffee and the operation of the machine?
First of all, pay attention to what the coffee is made from in the machine. Raw materials can be natural (ground grains) or soluble. The properties and criteria for choosing a coffee machine depend on this.
Automatic coffee machine
If the vending machine prepares coffee from natural beans, the quality and taste of the drink is significantly increased. But the price of the machine itself is also growing.
Please note if the coffee machine is equipped with a coffee grinder. It depends on how difficult the process of filling the machine will be. When buying a vending machine with a coffee grinder, find out what its wear life is, since this is one of the most important points, it affects both the performance of the entire device and the taste of coffee. If you buy a used vending machine, the knives in the grinder are most likely worn out and the coffee will taste worse.
Find out how the coffee is brewed. There are two types of brewing: espresso and french press. Espresso, or the high pressure method, is when water converted to steam is forced through the ground coffee bean under high pressure. The taste of the drink is slightly thicker and richer than with the low pressure method. The French press (low pressure method) means that hot water simply passes through the coffee, which is brewed like in a regular cup. Ultimately, the drink is redirected to the glass, and the thick to a special container.
In such machines, filters of two types are used: permanent (metal or plastic) or replaceable (paper). The first option requires regular maintenance of the filter, as it needs to be cleaned from time to time. With the second option, you just need to constantly change the filters.
Instant coffee machine
This machine is filled with instant coffee powder. The machine dispenses coffee by itself and then dilutes it with hot water. The mixing parameter is important: it can be carried out both in the glass itself and in a separate container. It is believed that the method of mixing in a cup is good because the machine needs cleaning and special maintenance much less often.
The disadvantage of this method is that it is imperative to check how well the process is carried out: not all machines mix coffee well. When buying, you need to test such a vending machine by preparing a portion of coffee in it. The presence of sediment at the bottom indicates that the mixing is not thorough enough.
