TWI735331B - Cold-pressed method for cigarette tar and nicotine remove by cryogenic- sine wave pressure cycling procedure - Google Patents

Abstract

In general, this inventive procedure is conducted to remove a huge amount of tar and nicotine cotained in tobacco that is made up of cigarette and cigar. First of all, the pressure of tank is vacuumed to below 0.5 atm. With LN ₂, the temperature can gradually decrease from room temperature to below – 80°C in order to let LN ₂penetrate into every tiny pore of tabacco. During the process, 1- 5 atm sine wave pressure will be applied, and thus the tar and nicotine will be squeezed out and exhausted along with N ₂gas through check valve of gas release pipe. Finally, the tar and nicotine in tabacco can be removed tremendously.

Description

Method for removing tar and nicotine in tobacco products by cold-hot high-pressure cycle cold-shrink density extrusion

The present invention relates to a method for removing tar and nicotine from cigarettes by cold-heat high-pressure cycle cold shrinkage density extrusion, and mainly refers to a method for removing tar and nicotine from cigarettes.

Conventional cigarettes, cigars, tobacco and other tobacco products contain harmful substances such as nicotine and tar. After the nicotine enters the human body, it will cause rapid heartbeat and blood pressure. After long-term absorption, it is more likely to cause cardiovascular disease. In addition, tar is a kind of The yellow viscous substance contains a variety of carcinogens, which will seriously endanger human health after entering the human body in large quantities.

At present, in order to reduce the harm of smokers and second-hand smokers, a longer or special filter can be installed in the smoke product, so that most of the nicotine and tar can be attached to the filter after the smoke from the burning product enters the filter. Reduce the number of people inhaled.

However, the method of increasing the filter will cause the smoker to not easily inhale the flue gas uncomfortable, and may cause the smoker to smoke harder, causing the flue gas to penetrate the human body and affect the health.

The object of the present invention is to provide a method for removing tar and nicotine in tobacco products.

The method of the present invention for removing tar and nicotine from cigarettes by cold-hot high-pressure cycle cold-shrinking density extrusion includes the following steps: S1 is equipped with a cold and hot high pressure cycle cold shrink density extruder with a containing tank, and the tobacco products are placed in the containing tank; S2 evacuates the accommodating tank; S3 cools down and condenses the holding tank, and puts it at a set low temperature for a set time; during the condensation process, a sinusoidal pressure of 1 to 5 atmospheric pressure is applied; S4 heats the accommodating tank back to normal temperature and takes out the tobacco after standing for a period of time.

In one embodiment of the present invention, the cold-heat high-pressure cycle cold shrinkage density extrusion machine has a closed containing tank, the containing tank is connected to an external liquid nitrogen pipeline and a vacuum device, the liquid nitrogen pipeline is connected to a liquid nitrogen tank, and The accommodating tank is provided with a one-way pressure relief valve, a heating device is provided in the accommodating tank, and a number of brackets are arranged at different height positions in the accommodating tank.

In an embodiment of the present invention, the S2 step is to evacuate the accommodating tank to make the pressure in the accommodating tank below 0.5 atmospheric pressure.

In an embodiment of the present invention, the S3 step is to start liquid nitrogen, so that the temperature in the containing tank is gradually reduced from normal temperature to 0°C to -196°C.

In an embodiment of the present invention, the process of cooling, condensing, and standing for a period of time when the temperature reaches the set low temperature in step S3 is 3-6 hours.

In an embodiment of the present invention, the process of heating back to normal temperature in step S4 and standing for a period of time is 1-3 hours.

The tobacco product of the present invention can be condensed at a low temperature and combined with a sinusoidal pressure wave in step S3 to push liquid nitrogen into the capillary pores of the tobacco of the tobacco product; and in step S4, the temperature of the liquid nitrogen is raised and the cell wall of the tobacco skin is blasted, and the inside of the tobacco is precipitated. The nicotine, tar.

Please refer to Figures 1 to 3. The method of the present invention for removing tar and nicotine from cigarettes by cold-heat cycle cold shrinkage density extrusion includes the following steps: S1 is equipped with a cold and hot high pressure cycle cold shrink density extruder with a containing tank, and the tobacco products are placed in the containing tank; S2 evacuates the accommodating tank; S3 cools down and condenses the holding tank, and puts it at a set low temperature for a set time; during the condensation process, a sinusoidal pressure of 1 to 5 atmospheric pressure is applied; S4 heats the accommodating tank back to normal temperature and takes out the tobacco after standing for a period of time.

The cold-heat high-pressure cycle cold-shrink density extruder 1 of the present invention has a closed accommodating tank 11, the accommodating tank 11 is connected to an external liquid nitrogen pipeline 21 and a vacuum device 3, and the liquid nitrogen pipeline 21 is connected to a liquid nitrogen tank 2 In addition, the accommodating tank 11 is provided with a one-way pressure relief valve 12, and a heating device 4 is provided in the accommodating tank 11, and the accommodating tank 11 is provided with a number of brackets 5 at different heights to hold agricultural products 6.

In step S1 of the present invention, the tobacco product can be mounted on the bracket 5 of the cold-heat high-pressure cycle cold shrinkage density extruder 1. The tobacco product 6 can be cigarettes, cigars, tobacco or other tobacco products 6; and the S2 step is performed by a vacuum device 3 Vacuum the accommodating tank 11 and make the pressure in the accommodating tank 11 below 0.5 atmospheric pressure.

The step S3 of the present invention is to start the liquid nitrogen 22, so that the temperature in the containing tank 11 is gradually reduced from normal temperature to 0°C~-196°C. The preferred condensation temperature is below -40°C, and the liquid nitrogen 22 is absorbed during the condensation process. The heat energy of the items in the accommodating tank 11 is expanded and pressurized, and the pressure can be relieved by controlling the pressure relief valve 12 when the pressure of the accommodating tank 11 is increased to exceed the set pressure, and the condensing process is simultaneously applied to 1~5 The sinusoidal pressure of atmospheric pressure ravages the tobacco product 6, as shown in Figures 2 and 3. This embodiment applies a sinusoidal pressure of 1-3 atmospheric pressure to the accommodating groove 11, which can push liquid nitrogen 22 into the tobacco of the tobacco product 6. When the pores reach the set low temperature, let them stand for a period of time to ensure that all the tobacco pores of the tobacco product 6 are evenly impregnated with liquid nitrogen 22, and the condensation and standing time process can be 3-6 hours.

In step S4 of the present invention, the heating device 4 in the accommodating tank 11 is operated to heat the accommodating tank 11 to normal temperature, and the process of heating to normal temperature and standing for a period of time can be 1 to 3 hours, so that the tobacco pores of the tobacco product 6 The infiltrated liquid nitrogen 22 will rapidly expand. This process bursts the cell wall of the tobacco epidermis of the tobacco product 6, which can precipitate most of the nicotine and tar in the tobacco.

The nicotine and tar precipitated by the present invention can be discharged out of the accommodating tank 11 with high-pressure nitrogen, so the nicotine and tar content of the tobacco 6 itself can be greatly reduced, and the damage of the tobacco product 6 to the human body can be greatly reduced. Mouth is a more permanent cure.

Based on the above, the present invention is a novel method, and more effectively reduces the nicotine and tar in the tobacco products, and the foregoing embodiments are examples of creation, not the limitation of this creation, and equivalent changes made according to the spirit of this creation are also Should belong to the scope of this creation.
