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

Embodiment 1

[0023] The mass percentage composition of an environment-friendly shredded tobacco expanding agent composition in this embodiment is: 90% of pentafluoropropane and 10% of ethanol.

[0024] The preparation method is to weigh the raw materials according to the mass percentage of 90% pentafluoropropane and 10% ethanol, then place them in a preparation tank, stir and mix evenly, and then pressurize and filter with a 600-mesh filter to make the Environmentally friendly shredded tobacco expander composition, its technical index data are shown in Table 2.

Embodiment 2

[0026] The mass percentage composition of an environment-friendly shredded tobacco expanding agent composition in this embodiment is: 80% of pentafluoropropane and 20% of isohexane.

[0027] The preparation method is to weigh the raw materials according to the mass percentage of 80% of pentafluoropropane and 20% of isohexane, then place them in a preparation tank, stir and mix evenly, and then pressurize and filter with a 600-mesh filter to prepare the present embodiment. The environment-friendly shredded tobacco expansion agent composition, its technical index data are shown in Table 2.

Embodiment 3

[0029] The mass percentage composition of an environment-friendly shredded tobacco expanding agent composition in this embodiment is: 99% of pentafluoropropane and 1% of diethyl ether.

[0030] The preparation method is to weigh the raw materials according to the mass percentage of 99% pentafluoropropane and 1% diethyl ether, then place them in a preparation tank, stir and mix evenly, and then pressurize and filter with a 600-mesh filter to make the Environmentally friendly shredded tobacco expander composition, its technical index data are shown in Table 2.

Abstract

The invention relates to an environment-friendly cut tobacco expanding agent composition, which comprises the following components in percentage by weight: 50-99 percent of hydrofluoroalkane and 1-50 percent of alcohol or ether or alkane, wherein the hydrofluoroalkane is one or any combination of several kinds of pentafluoropropane, pentafluorobutane, decafluoropentane or methoxyl heptafluoropropane, preferably 80-99 percent of hydrofluoroalkane and 1-20 percent of alcohol or ether or alkane; and more preferably, 90-99 percent of hydrofluoroalkane and 1-10 percent of alcohol or ether or alkane. The environment-friendly cut tobacco expanding agent composition has favorable chemical stability; and the ozone depletion potential (ODP) index of the environment-friendly cut tobacco expanding agent composition is zero which is far lower than CFC-11, so the environment-friendly cut tobacco expanding agent composition is beneficial to the environmental protection.

Description

technical field [0001] The invention relates to the chemical treatment field of tobacco, and more specifically relates to an environment-friendly shredded tobacco expander composition. Background technique [0002] The traditional shredded tobacco expansion agent used in the tobacco industry is CFC-11 (trichlorofluoromethane), and its expansion process is to fully soak the condensed volatile substance CFC-11 with shredded tobacco, and then heat the shredded tobacco soaked to trigger the The rapid volatilization of the expansion medium diffuses outward through the cell wall of the shredded tobacco, restoring the volume and shape of the tobacco cells to the original volume and shape before harvesting. Finally, after moisture regaining and other processes, the expanded shredded tobacco is made in line with normal production and final conditions. Product in good storage condition. The expanded shredded tobacco can reduce the tar content in the tobacco and improve the taste of t...
