Latest Patents
One of Ravi Prasad's latest patents is a process and apparatus for the impregnation and expansion of tobacco. This innovative process employs carbon dioxide gas to adjust the tobacco's temperature and OV content before contact. The method is particularly suitable for tobacco with a high bulk density, which can be achieved by compacting or compressing the tobacco prior to impregnation. The process allows for a short cycle impregnation in a specialized apparatus, following a thermodynamic path that controls the condensation of carbon dioxide gas on the tobacco. This liquid carbon dioxide evaporates during depressurization, helping to cool the tobacco bed uniformly. After the impregnation process, the tobacco can be expanded immediately or stored in a dry atmosphere for subsequent expansion.
