Embodiment 2

[0025] According to pentafluoropropane 71.5%

[0026] Pentafluorobutane 28%

[0027] The mass ratio of perfluorobutyl methyl ether or decafluoropentane 0.5% is taken by weighing raw materials, then placed in a preparation tank, stirred evenly, and then pressurized and filtered with a 600-mesh filter to obtain the cut tobacco expansion agent, and its indicators are as follows:

[0028] Test items

[0029] boiling point

[0030] The shredded tobacco expanding agent of the present invention has the characteristics of zero or very low ozone depletion potential, moderate boiling point, low toxicity, good safety and good chemical stability, etc., and can completely replace CFC-11 in the tobacco manufacturing industry as the shredded tobacco expanding agent.

Abstract

The invention discloses a shredded tobacco expander, which is composed of dichlorofluoroethane and perfluoropentane or perfluorohexane in a certain proportion, and has zero or very low ozone depletion potential, moderate boiling point, safety and low Toxic, non-flammable, volatile and other characteristics, it can replace CFC-11 in the tobacco industry as tobacco expansion agent.

Description

technical field [0001] The invention relates to an expanding agent, more specifically an 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 addition...
