Green smoking tips and methods of mass manufacturing of green smoking tips comprising extracting volatile compounds and carbonizing hollow plant stem cuts.
Claims15
A method of mass manufacture of green smoking tips comprising:
- cutting hollow plant stems that are between 4 mm and 30 mm in diameter into segments having a length of between 5 mm and 60 mm;
- extracting volatile compounds from the segments by boiling the segments in a solvent;
- and
- carbonizing the segments through heat treatment by heating the segments after they have been boiled in the solvent until starches in the segments begin to caramelize and the segments turn to a golden/tan color.
