The difference between Italian Coffee Grinder and other Coffee Grinder
Generally speaking, the parallel grinding disc has the advantages of fast rotational speed, fast grinding and more uniform grinding, while the disadvantage is easy to heat and relatively short life, while the tapered grinding disc has the advantages of not easy to heat and long life, and the disadvantage is slow and uneven. At present, the Japanese Fuji ghost tooth grinding plate can grind more uniform coffee powder, at the same time produce less fine powder, and the grinding efficiency is higher. But it is not suitable for espresso extract.

Coffee roasting heat source heat conduction and convection
At present, the most widely used baking equipment is semi-direct fire (semi-hot air) baking, where the half is only relative to the baking heat source, not the thermal efficiency distribution ratio, such as the probat baking machine we use, in terms of thermal efficiency distribution, it is about 3(direct fire):7(hot air) or 2:8, rather than 5:5. In this article, I try to analyze the characteristics of these two heat sources.
