Problems solved by technology

[0004] At present, the expansion agent widely used in foreign countries is carbon dioxide, but the equipment using carbon dioxide is expensive, and each equipment is as high as 40-50 million yuan. Considering the manufacturing cost, it is difficult for my country's tobacco industry to accept it. Due to the low boiling point of carbon dioxide dry ice, it is not easy to recycle. , which increases the emission of carbon dioxide into the atmosphere, which is not conducive to environmental protection

Abstract

The present invention relates to a shredded tobacco expansion agent composition. The first shredded tobacco expansion agent composition of the present invention is composed of pentafluorobutane and heptafluoropropane, the second is composed of pentafluorobutane and hexafluoropropane, and the third is composed of pentafluorobutane and heptafluoropropane. Butane and pentafluoropropane, the fourth is composed of pentafluorobutane and tetrafluoroethane, and the fifth is composed of pentafluorobutane and decafluoropentane. The cut tobacco expander composition of the present invention has an ozone depletion potential (ODP) of zero, moderate boiling point, safety, low toxicity and nonflammability, and can replace CFC-11 as a cut tobacco expander in the tobacco industry.

Description

technical field [0001] The invention relates to chemical substance treatment of tobacco, more precisely relates to an environment-friendly shredded tobacco expander composition used in the tobacco processing industry. Background technique [0002] At present, the cut tobacco expansion agent used in the tobacco industry is CFC-11 (trichlorofluoromethane). The expansion process is to fully soak the condensed volatile substance CFC-11 with the cut tobacco, and then heat the soaked cut tobacco to trigger the The rapid volatilization of the above-mentioned expansion medium, so as to diffuse outward through the cell wall of the cut tobacco, restore the volume and shape of the tobacco cells to the original volume and shape before harvesting, and finally through the process of rehydration and other processes, the expanded cut tobacco is made in line with normal production and Product in best storable condition. The expanded shredded tobacco can reduce the tar content in the tobacco...
