Technical Field

The invention relates to the technical field of cigarette flavors, in particular to an extraction process of a plant flavor for a cigarette which is not combusted by heating.

Background

The tobacco product which is not burnt by heating is an important innovation breakthrough of the tobacco product in the world in recent years, compared with the traditional cigarette, the tobacco product which is not burnt by heating can obviously reduce the harm, reduce the side stream smoke, avoid the fly ash from flying, and simultaneously can provide the smoking effect and the taste enjoyment similar to the traditional cigarette, thereby gaining the market acceptance. IQOS of Feimo tobacco group and GLO of Enume tobacco group do not burn tobacco products by electric heating, and have remarkable sale results in markets such as Japan, Korea and Europe and show good development tendency.

Compared with the traditional cigarette, the largest technical advantage of heating the non-combustible tobacco is that the tobacco raw material is not combusted, but is heated and distilled at the temperature of 250-500 ℃ to obtain smoke, so that the harmful ingredients are obviously reduced. However, the smoke components are changed from combustion release to heating and dry distillation release, which has great influence on the aroma components of the smoke. The cigarette perfume technology is one of the core technologies in cigarette manufacture, and is used for modifying the defects of a tobacco leaf or leaf group formula, so that the toughness and the combustibility of tobacco can be improved by adding materials and fragrance, the irritation of smoke can be reduced, and the anti-corrosion capability of the tobacco can be improved. The fragrance of the product is improved by adding fragrance to cover up miscellaneous gas and set off fragrance, so that the fragrance of cigarettes can be enriched and corrected, and the fragrance of the cigarettes can be kept stable and unchanged. In addition, the perfume material can shield certain smell and can also shield, dilute and neutralize miscellaneous gas in the cigarette. On the other hand, on the basis of ensuring external flavoring and cigarette fragrance, the cigarette can be endowed with different fragrance styles so as to meet the requirements of different consumers.

The traditional essence and spice is obtained by extraction modes such as alcohol extraction, water extraction or molecular distillation, the spice generates complex chemical change after being combusted in the traditional cigarette to release aroma, the aroma which is not combusted when being heated is obtained by cracking at the temperature of 250-400 ℃, certain requirements are provided for the volatility and low-temperature cracking of the spice, the effect of the extraction modes on adding the spice into the cigarette which is not combusted when being heated is not obvious at present, along with the increasing popularization of the cigarette which is not combusted when being heated, the research on the special spice for the cigarette which is not combusted when being heated is urgently needed to be carried out, and the blank on the one hand is filled.

Therefore, the present invention has been completed through a large number of experimental studies and summaries based on the prior art.

Disclosure of Invention

The invention aims to provide an extraction process of plant spice of a heating non-combustion cigarette, which reduces fragrant substances into a smoking section of the heating non-combustion cigarette, ensures the pure fragrance of plant raw materials and does not contain any chemical smell.

The technical scheme of the invention is as follows: an extraction process of a heat non-combustible spice comprises the following steps:

(1) pulverizing plant materials to 40-80 mesh, adding 0.5-1 times of water into plant powder, and mixing to obtain plant water powder;

(2) putting the plant water powder into a wet distillation device, and carrying out heating pyrolysis at different temperature gradients; the temperature gradient is 0-130 ℃, 130-240 ℃, 240-350 ℃ and 350-500 ℃, the wet distillation time of each temperature section is 90min, the temperature section of 0-130 ℃ belongs to a steam distillation section and wet distillation, the boiling point of some essential oil components can be reduced under the condition of steam existence, the perfume of the temperature section can be better brought out, the temperature section belongs to a carbonization and gasification stage after 130 ℃, the fragrance components are cracked through a temperature mode of simulated heating and non-combustion, the liquid perfume is collected after condensation, the temperature sections are divided into 5 temperature sections, and the perfume with different volatility and boiling points can be better collected after 90min cracking of each temperature section;

the atmosphere in the wet distillation device can be air, oxygen or nitrogen, on one hand, materials can generate different products under different atmospheres;

(3) and collecting the gas and the liquid at the outlet end of the dry distillation equipment through a condensation collecting device to obtain the spice suitable for heating the non-burning cigarettes.

In the extraction process, in order to improve the extraction efficiency of the fragrant raw materials, the contact surface area of materials needs to be increased, the materials are crushed, the preferred mesh number of the materials is 50-60 meshes, the added water in the materials is an essential oil substance with a low boiling point for better extraction, and the preferred added water amount is 0.6-0.8 times of zero.

The plant raw materials are nontoxic plant raw materials such as tobacco, mint leaves, coffee, roses, passion fruits and the like, and the selected plant raw materials are known in the industry or are allowed according to relevant regulations and are all commercially available products.

The temperature of the condensing device is set to be 2-8 ℃, the aroma components cracked by high temperature are all gases, are difficult to collect and cannot be used in heating non-burning cigarettes, the aroma substance gases need to be condensed, and the preferable condensing temperature is 2-5 ℃.

The height of the feeding end of the wet distillation device is 5-10cm higher than that of the perfume outlet end, the height difference between the feeding end and the discharging end is beneficial to the perfume to flow out from the discharging end, the perfume yield is increased, and the preferable height difference is 5-8 cm.

The atmosphere in the wet distillation device is preferably air in a simulated heating non-combustion mode, on the other hand, the airflow can drive the aroma to flow, the extraction efficiency is accelerated, and the preferred flow rate is 0.3-0.5 cm/s.

The extraction process of the invention extracts according to the pyrolysis principle of heating and non-combustion, reduces the fragrant substances to the smoke generating section of the heating and non-combustion cigarette, ensures the pure fragrance of the plant raw materials, does not contain any chemical smell, combines the dry distillation and the steam distillation extraction, well extracts the fragrant substances at the heating and non-combustion pyrolysis temperature section, has high reduction degree of the plant fragrance when the cigarette is not combusted by smoking and heating, improves the consumption experience, is simple in process, is environment-friendly, and is suitable for industrial production.
