Glass, glass, glass…
The main roasting chamber has been made of glass since it was first built 10 years ago. The reason for this is that environmental hormones are not released at high temperatures. Therefore, it can avoid the problem of mixing harmful substances during roasting. Additionally, it is easy to clean and durable if no special impact is applied, making it suitable for permanent use. Despite these advantages, the biggest reason for using glass is that it allows easy monitoring of the roasting progress. While the roasting situation can be monitored programmatically through temperature and humidity sensors and sound frequency analysis, visual observation is very intuitively useful for checking the progress. Moreover, it stimulates emotions when an individual operates it at home.
