Problems solved by technology

However, with the continuous improvement and pickiness of people's requirements for smoking quality and taste, the application of CO2 dry ice expanded shredded tobacco in finished cigarettes has been challenged, especially in the application of high-end cigarettes.
like image 3 As shown, according to the current processing technology, entering CO 2 CO before hot end sublimator 6 of dry ice expansion line or expansion tower 2 Dry ice shredded tobacco 1, due to the dry ice formed on the surface and inside of the shredded tobacco, the shredded tobacco becomes hard and brittle. After being beaten by the feeding electronic scale 2 and raked by the feed air lock 5 and rolled by the valve body and the rotating valve core The impact of the raking of the mill or discharge air lock 8 and the rapid expansion and transportation of the hot air in the sublim

Embodiment 1

[0033] A method for expanding shredded tobacco, characterized in that it comprises the following steps:

[0034] ①Impregnation: Use CO2 liquid to impregnate shredded tobacco with a certain amount of moisture to form dry ice shredded tobacco 1;

[0035] ② Loosening: Loosen dry ice shredded tobacco 1 once to reduce lumps.

[0036] ③Storage: Buffer the material and keep it in the state of dry ice shredded tobacco.

[0037] ④Secondary loosening: Secondary loosening is performed on the cut dry ice tobacco 1 to further reduce lumps.

[0038] 5. Quantitative feeding, the dry ice shredded tobacco 1 impregnated through the expansion medium is sent into the blowing device 10 evenly by quantitative feeding equipment such as metering tube 2 and electronic scale or conveyor belt 3;

[0039] ⑥Pre-expansion and impurity removal and air extraction: the dry ice shredded tobacco 1 impregnated with the expansion medium enters the blowing device 10, and in this embodiment, the shredded tobacco ...

Embodiment 2

[0046] The differences between this embodiment and the first implementation are as follows:

[0047] 1. Steps of a method for expanding shredded tobacco 6. In pre-expansion and impurity removal and air extraction: the temperature of the airflow during blowing is normal temperature; the dry ice shredded tobacco 1 impregnated with the expansion medium is located above the blowing pipe 101 of the blowing device 10; the blowing pipe 101 When under the dry ice shredded tobacco 1, it is better to have a slightly suspended state of the dry ice shredded tobacco 1. In the present embodiment, the air velocity discharged from the blowing pipe is 10 m / s;

[0048]2. The blowing device 10 is installed at the lower part of the outlet 31 of the conveying device at the front end of the feed air lock 5 of the sublimator 6. In this embodiment, the blowing pipe 102 of the blowing device 10 is located below the outlet 31 of the conveyor belt 3 of the conveying device. The air blowing pipe 102 is p...

Embodiment 3

[0051] The differences between this embodiment and the first implementation are as follows:

[0052] 1. Steps of a method for expanding shredded tobacco ⑥ During pre-expansion and impurity removal and air extraction: the temperature of the airflow during blowing is 200°C; the airflow velocity discharged from the blowing pipe is 10 m / s;

[0053] 2. The airflow velocity discharged from the blowing pipe 102 on the blowing device 10 is 10 m / s.

[0054] The rest are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to a method for expanding tobacco shreds and equipment used in the method. The method is characterized by comprising the following steps: (1) dipping; (2) loosening; (3) storing; (4) secondary loosening; (5) quantitative feeding; (6) pre-expanding, purification and air extraction: the tobacco shreds dipped by an expanding medium are pre-expanded in air blowing equipment, and the tobacco shreds dipped by the expanding medium are delivered to the air blowing equipment which blows air to the shreds dipped by the expanding medium; and miscellaneous gas volatilizing at the pre-expansion of the tobacco shreds and CO2 are pumped off by an exhaust tube; (7) expanding: the pre-expanded tobacco shreds are quickly delivered to a sublimator by a feeding air lock and is mixed with hot air flow in the sublimator for continuous expansion; and (8) cooling and shaping. The method has the advantages of improving the toughness, the whole cut rate and long shred rate of the expanded tobacco shreds, reducing the breakage of the expanded tobacco shreds, eliminating the miscellaneous gas and lowering energy consumption in the production process.

Description

technical field [0001] The invention relates to the tobacco processing industry, in particular to a technology for processing shredded tobacco by using CO2 dry ice as an expansion medium in a hot gas flow expansion method. Background technique [0002] CO 2 Dry ice expansion technology is a mature technology for processing shredded tobacco by using expansion medium and hot air expansion method. However, with the continuous improvement and pickiness of people's requirements for smoking quality and taste, the application of CO2 dry ice expanded shredded tobacco in finished cigarettes has been challenged, especially the application in high-end cigarettes is more cautious. like image 3 As shown, according to the current processing technology, entering CO 2 CO before hot end sublimator 6 of dry ice expansion line or expansion tower 2 Dry ice shredded tobacco 1, due to the dry ice formed on the surface and inside of the shredded tobacco, the shredded tobacco becomes hard and b...
