NUVO Hand Coffee Bean Roaster NV CCR Semi-Hot air method Aluminum & Ceramic Coating

What is semi-Hot air method roasting?
The advantage of the direct-burning type that directly applies heat to the roaster and the heat is transmitted by the hot air to the roasting,
It is roasted uniformly by roasting method which circulates heat, and it has the feature that raw bean's original flavor is saved well.
Roasting air holes to create the optimum temperature
There is a remarkable scientific principle even in the Evenly arranged holes that are pierced back and forth.
It is an important hole that enables the semi-wind roasting using the principle of thermodynamics.
This ensures that the roasting temperature of 220 degrees is maintained.
