At the beginning it is worth explaining a certain misunderstanding – not every mill in the espresso machine had coffee the same. On the market we will find two main types of clash mills: ceramic and steel. Here are the differences between them.
Grinder and the temperature of the grains
We often hear that steel grinders overheat coffee during grinding. This is a myth that is worth overthrowing. Tests show that the temperature in both types of mills is practically identical during normal use. The differences appear only with intense, continuous swarm – for example in a cafe where the machine works non -stop. Temperature It is a matter of grinding time and construction of the grinder, not the Żaren material itself.
Durability and resistance to damage
Steel mills have an advantage here. They are much more resistant to mechanical damage. A random pebble or twig, which sometimes hit in coffee bags, will not hurt them. Meanwhile, ceramic ardles can in such a situation break or chip off, which means the need to replace the entire grinder. However, ceramic mills are more durable in terms of wear – They do not exterminate as fast as steel, so their grinding quality remains more stable for years.
Precision of grinding
Evenly grinding and the amount of fine dust in coffee It depends primarily on the quality of Żaren and the precision of their settings, not the material itself. Excess dust can affect the taste of the infusion, but both steel and ceramic mills can produce it depending on the degree of grinding and construction of the grinder. However, ceramic mills often offer very even grinding for a long time, because they do not exterminate as fast as steel.
What about the volume of work?
Steel mills can be slightly louder than ceramic because ceramics naturally suppress sounds than steel, but the difference is usually marginal and depends on the entire design of the coffee machine. So this can be considered another myth to overthrow – none of the types of mills is by nature clearly louder or quieter. The volume of work depends mainly on the quality of the engine and the damping of the casing of the coffee. The cheap espresso machine will rather make noise regardless of the type of grinder.
Who is the ceramics for whom for?
The quality of grinding depends not only on the material, but also on the design and precision of the grinder. The ceramic grinder will work in a home espresso machine that burns a few coffee a day. It is long enough and precise for the average user. Steel mills are a better choice for a very intense.
Prices of espresso machines with a steel and ceramic grinder
Price The espresso machine should not be the selection criterion between steel and ceramics. In each price shelf you will find devices with these two types of mills. However, it is worth paying attention to the possibility of adjusting the grinding degree – it is more important than the Żaren material itself.
