Abstract
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
The present invention relates to a kind of swelling agent, relate to an a kind of novel environment friendly tobacco expanding agent that grows tobacco and use in the processing industry or rather.
Background technology
The tobacco expanding agent that present tobacco business mainly uses is CFC-11, its expansion process step is: CFC-11 fully soaks with pipe tobacco with the frozen state volatile materials, the pipe tobacco heating that to be soaked then, cause the quick volatilization of described inflating medium, thereby it is extrapolated by its cell membrane through pipe tobacco, make tobacco cell return to volume and the shape that is had before the former harvesting,, but the pipe tobacco after expanding is made the product that meets production and storage configuration again through PROCESS FOR TREATMENT such as moisture regain.Pipe tobacco after overexpansion can reduce the taste that the tar content in the tobacco improves cigarette, because the pipe tobacco volume that expands becomes big, adds it to can reduce tobacco in the cigarette cost in proportion, so also have remarkable economic efficiency in addition.
Yet the ODP ODP index of described swelling agent CFC-11 is 1.0, thereby it is very big to the destruction of ozone layer, the use that has been under an embargo in the world at present, and China also reduces the supply consumption year by year, all eliminates by 2006.
External widely used swelling agent is a carbon dioxide at present, but uses carbon dioxide plants to cost an arm and a leg, and every equipment reaches 4-5 10,000,000 RMB, and China's tobacco enterprise is considered beyond affordability from manufacturing cost.
Summary of the invention
Having the purpose of this invention is to provide a kind of ODP index is zero or very low, and every technical data all approaches the environment-friendly type tobacco expanding agent of CFC-11.
The present invention realizes by following composition, the consisting of of said composition: (quality)
Dichloro one fluoroethane 90-99%
Perflenapent or perfluor hexane 1-10%
The present invention also can realize that said composition consists of by following composition:
Pentafluoropropane 70-98%
3-pentafluorobutane 1-30%
Decafluoropentane or perfluoro butyl methyl ether 0.5-2%
Above-described raw material all adopts primes, and described composition can evenly mix by aforementioned proportion, weighs to be placed in the preparing tank and stirs, and makes it to mix, and carries out pressure filtration with 600 purpose filters then, obtains a kind of tobacco expanding agent of the present invention.
The composition technical data of the present invention after modification is as follows:
| Test event | Unit | CFC-11 | New swelling agent |
| Outward appearance | Water white transparency liquid is stopped | Colourless transparent liquid | |
| Boiling point | ℃ | 24 | ?20-40℃ |
| Freezing point | ℃ | -111 | -100--120 |
| Density | G/cm 3(25℃) | 1.476 | ?1.25-1.42 |
| Saturated vapour pressure | Mpa | ?0.106 | ?0.068-0.100 |
| ?ODP | ?1.0 | ?0.00-0.086 | |
| The latent heat of vaporization | KJ/Kg | ?180.3 | ?200-221 |
| Viscosity | mpas(20℃) | ?0.43 | ?0.40-0.45 |
| Residual quantity | PPm | After 7 days, 5-7 | Blew 4.5-6.0 12 hours |
| Toxicity/LD 50 | ?mg/kg | ?1436.4 | ?1436-1654 |
By last table, as can be seen: its ODP of the novel swelling agent ODP index after modification of the present invention then is significantly less than CFC-11.The moderate boiling point of this novel swelling agent if boiling point is too low, then is difficult for reclaiming, transporting and store; If the too high capacity that then need increase equipment of boiling point, energy consumption become big, operating cost increases.So being 20-40 ℃, its boiling point suits.Described novel swelling agent is compared with CFC-11, and when with the mouse stomach acute toxicity testing, this novel swelling agent is slightly less than CFC-11 to the acute toxicity of mouse.The residual quantity of described novel swelling agent also is lower than CFC11.
The used bloating plant of described swelling agent for shredded tobacco is with to be used for the CFC-11 bloating plant identical, technological process is also taken charge of substantially mutually, need only change the processing jar and improve refrigerator power, improve evaporator temperature to 90-100 ℃, the pressure of work jar reaches 0.6-0.7Mpa when leading to medium, makes work jar temperature reach 100-110 ℃ when leading to steam and gets final product.
When described novel swelling agent was heated in its expansion process process, its chemical composition did not change, and can find out that it has very high decomposition temperature and good chemical stability.
Further specify the present invention below by embodiment.
