5. Conclusion s and Perspectives
Further applications can be developed based on this tech nology. It was demonstrated the coffee roaster
can be used to roast cocoa and broad beans too. Pop -corn can even be produced easily, provided a
te mpered glass is placed in front of the cylinder to prevent the corn beans to pop out of the cylinder! The
same concentrator can be used for cooking and ot her application can be developed, such as milk
pasteurization, essential oil extraction...
The current state of development of the technology is very promising. The concept proved to
yield good results like illustrates Figure 8 . The technology raises attention and people from the
co mmunity seem interested. The perspectives of this solar roasting technology are great.
