The present invention discloses a new type tobacco shreds expanding agent. It can be formed from dichloromonofluoethane and perfluoropentane or / and perfluorohexane according to a certain proportion or formed from pentafluoro-propane, pentafluorobutane and decafluoropentane or / and perfluorobutylmethyl-ether according to a certain proportion. It is characterized by that its ozone consumption latent energy value is zero or low, its boiling point is moderate, and it is safe and low-toxic, incombustible and volatile, and can be used as expanding agent for tobacco shreds instead of CFC-11 in tobacco industry.
Description
technical field [0001] The invention relates to an expanding agent, more specifically to a novel environmentally friendly shredded tobacco expanding agent used in the tobacco processing industry. Background technique [0002] At present, the cut tobacco expansion agent mainly used in the tobacco industry is CFC-11, and the expansion process steps are: fully soak the condensed volatile substance CFC-11 with the cut tobacco, and then heat the soaked cut tobacco to trigger the rapid volatilization of the expansion medium , so that the tobacco cells are pushed out through the cell wall of the shredded tobacco to restore the volume and shape of the tobacco cells to the original volume and shape before harvesting, and then undergo moisture regain and other processes to make the expanded shredded tobacco into a product that meets the production and storage conditions. The expanded shredded tobacco can reduce the tar content in the tobacco and improve the taste of the cigarette. In ...
