Description

Technical Field

[0001] The present application relates to the field of tobacco technology, and in particular to a method and system for preparing tobacco extract. Background Art

[0002] Heated cigarettes are an emerging tobacco product that releases tobacco extracts through heating rather than combustion, providing users with a smoking experience similar to traditional cigarettes while reducing the production of tar and other harmful substances. Due to the lower heating temperature, heated cigarettes are unable to fully release tobacco components, resulting in a weak aroma. Therefore, the addition of tobacco extracts to enhance the aroma of heated cigarettes is a key factor influencing the user experience.

[0003] Tobacco extract is extracted from tobacco and contains tobacco's natural aroma compounds. Compared to other natural flavors, tobacco extract is more compatible with heated cigarettes, enhancing the aroma and adding to the satisfaction of smoking. Currently, traditional tobacco extract extraction methods, such as solvent extraction or steam extraction, can produce tobacco extracts. However, these traditional methods are inefficient, with some components of the tobacco extract being lost and degraded during the extraction process, resulting in an incomplete composition of the final extracted tobacco extract.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] The embodiments of the present invention are written in a progressive manner.

[0051] The present application provides a method for preparing a tobacco extract. The method primarily addresses the technical issues of low process efficiency, partial component loss and degradation during the extraction process, and incomplete composition of the final extracted tobacco extract caused by conventional tobacco extraction methods such as solvent extraction or steam extraction.

[0052] like Figure 1 As shown, a method for preparing a tobacco extract comprises the following steps:

[0053] S1. In a confined space, ionization forms a plasma environment;

[0054] S2. Transporting tobacco raw materials into a confined space;

[0055] S3. Adjust the parameters within the confined space so that the tobacco raw material generates a vapor phase tobacco extract in a plasma environment;

[0056] Among them, the parameters include: pressure and temperature.

[0057] In step S1, the enclosed space adopts a sealable extraction tank, a storage body and a box body that can withstand high pressure and high temperature; a certain amount of gas is already stored in the enclosed space in step S1, and the gas in the enclosed space can be gas prepared and generated in the enclosed space, or gas input from outside the enclosed space.

[0058] It should be noted that in step S1, plasma is also called plasma, which is an ionized gas with high energy and high activity and overall electrical neutrality, formed by the outer electrons of the gas breaking free from the constraints of the atomic nucleus and becoming free electrons under the action of external conditions. Its specific composition is a collection of ions, electrons and non-ionized neutral particles.

[0059] Plasma is mainly used in the following three aspects: plasma smelting, which is used to smelt materials that are difficult to smelt by ordinary methods, such as high-melting-point metals such as zirconium (Zr), titanium (Ti), tantalum (Ta), niobium (Nb), vanadium (V), and tungsten (W); it is also used to simplify the process, for example, Zr, Mo, Ta, and Ti can be obtained directly from ZrCl, MoS, TaO, and TiCl respectively; plasma melting and rapid solidification can be used to develop hard high-melting-point powders, such as tungsten carbide-cobalt, Mo-Co, Mo-Ti-Zr-C, etc. The advantage of plasma smelting is the good consistency of product composition and microstructure, which can avoid contamination of container materials; plasma spraying, many equipment components should be wear-resistant, corrosion-resistant, and high-temperature resistant, for which a layer of material with special properties needs to be sprayed on their surface. Plasma deposition rapid solidification sprays specialty material powders into a hot plasma, melting them before spraying them onto a substrate (component). The powder rapidly cools and solidifies, forming a surface layer with a near-net-like structure, significantly improving spray quality. Plasma welding can be used to weld steel, alloy steel, aluminum, copper, titanium, and their alloys. It features smooth welds, a reworkable, oxide-free weld, and high welding speeds. It is also suitable for cutting steel, aluminum, and their alloys, with high cutting thicknesses.

[0060] In step S1, ionization is performed to form a plasma environment. Ionization can be performed using an electrode plate or an electrode tube. In one embodiment, the electrode plate bombards the gas in the enclosed space through discharge to form a plasma environment.

[0061] In step S2, the tobacco raw material refers to a raw material containing tobacco components, and the tobacco raw material may be tobacco leaves and / or tobacco stems.

[0062] In step S2, the components of the tobacco extract include nicotine, organic acids, phenolic compounds, aromatic compounds, terpenoid compounds, ketone compounds, ester compounds, and the like.

[0063] In step S2, the tobacco raw materials can be transported into the confined space by means of an auger conveyor, a belt conveyor, a roller conveyor, a plate chain conveyor, a mesh belt conveyor, a chain conveyor, etc. In actual application, in order to simplify the equipment, the tobacco raw materials can also be directly put into the confined space.

[0064] It should be noted that in step S3, the parameters in the confined space are adjusted so that the tobacco raw material generates a gaseous tobacco extract in a plasma environment. In actual application, the specific implementation method is: by adjusting the pressure in the confined space, the air pressure and airflow in the confined space are kept stable; by adjusting the temperature in the confined space, the tobacco raw material and the plasma environment in the confined space reach the reaction temperature, and the tobacco raw material undergoes reactions such as distillation and cracking under the combined action of high temperature and plasma environment.

[0065] It should be noted that the vapor phase tobacco extract generated in step S3 is an impure vapor phase tobacco extract, which is also mixed with solid phase tobacco waste.

[0066] Preferably, before step S1, the following steps are further included:

[0067] A1. Inject gas into the confined space;

[0068] Gases include nitrogen, oxygen, carbon dioxide, and noble gases;

[0069] In step A1, the gas injected into the enclosed space may include but is not limited to nitrogen, oxygen, carbon dioxide, argon, helium, neon and the like.

[0070] It should be noted that this method can achieve the effect of selectively extracting different components in the tobacco extract by ionizing different gases and adjusting the parameters in the closed space.

[0071] In Example 1, nitrogen gas is injected into a confined space to ionize the nitrogen gas to form a plasma environment. A tobacco raw material is introduced into the confined space, and the pressure of the confined space is increased to 1.5 standard atmospheres. The pressure and airflow in the confined space are maintained stable, and the temperature in the confined space is adjusted to 300°C. The tobacco raw material reacts under the action of the high temperature and the plasma environment, and the obtained vapor-phase tobacco extract mainly contains nicotine, organic acids, phenolic compounds, etc.

[0072] In the second embodiment, argon gas is injected into the confined space, the argon gas is ionized to form a plasma environment, tobacco raw materials are input into the confined space, the confined space pressure is increased to 1.5 standard atmospheres, the pressure and airflow of the confined space are kept stable, the temperature range in the confined space is adjusted to 250°C, and the tobacco raw materials react under the action of high temperature and plasma environment, and the main components of the obtained gas phase tobacco extract are nicotine, aromatic compounds, terpenoid compounds, etc. It should be noted that the injection of argon gas in this embodiment can create a relatively inert environment and reduce side reactions during the extraction process. Lower temperature and pressure can avoid excessive decomposition of the extract and ensure the quality of the extract and the integrity of the ingredients.

[0073] Example 3: Carbon dioxide is injected into a confined space to ionize the carbon dioxide to form a plasma environment. Tobacco raw material is introduced into the confined space, the confined space pressure is increased to 2 standard atmospheres, the pressure and airflow in the confined space are maintained stable, and the temperature in the confined space is adjusted to 350°C. The tobacco raw material reacts under the action of the high temperature and plasma environment, and the obtained vapor-phase tobacco extract mainly contains nicotine, ketone compounds, ester compounds, etc. It should be noted that in this example, the injection of carbon dioxide can adjust the pH of the reaction environment to a certain extent, which is conducive to the extraction of specific components. At the same time, the higher temperature can accelerate the extraction rate of the tobacco extract during the reaction.

[0074] Preferably, in step S1, ionization to form a plasma environment in a confined space is specifically performed as follows:

[0075] Ionizing the gas into plasma;

[0076] A plasma environment is formed in a confined space.

[0077] Preferably, after step S3, the method further includes the following steps:

[0078] B1. Processing of gas phase tobacco extract;

[0079] B2. Collect the treated gas phase tobacco extract.

[0080] Preferably, in step B1, the gas phase tobacco extract is processed by:

[0081] C1. Purify the gas-phase tobacco extract and output the purified gas-phase tobacco extract.

[0082] The purification of the vapor-phase tobacco extract in step C1 includes solid-gas separation of the vapor-phase tobacco extract, specifically removing solid-phase tobacco waste mixed with the impure vapor-phase tobacco extract generated in step S3, and outputting the purified vapor-phase tobacco extract. Specific purification methods can include filtration separation, gravity inertial separation, centrifugal sedimentation separation, electrostatic separation, etc. In specific applications, the vapor-phase tobacco extract can be purified using a cyclone-type gas-solid separator, a bag-type gas-solid separator, a wet gas-solid separator, etc.

[0083] Preferably, the processed gas phase tobacco extract is collected, e.g. Figure 2 As shown, the following steps are included:

[0084] D1. Condensing the purified vapor-phase tobacco extract to obtain a liquid-phase tobacco extract;

[0085] D2. Collect and store the liquid tobacco extract.

[0086] It should be noted that condensation refers to the condensation of a gas or liquid when it is cooled, such as water vapor when it is cooled and becomes water, and water when it is cooled and becomes ice. In step D1, condensation is the process of changing the gaseous tobacco extract after purification from a gaseous state to a liquid state to obtain a liquid tobacco extract. In specific application processes, condensation can be achieved by devices such as a condensation tower, a coiled-tube condenser, and a box-type condenser.

[0087] The collection and storage in step D2 can be performed using a liquid storage tank to collect and store the liquid tobacco extract.

[0106] As an embodiment, a conveyor inputs tobacco raw materials and gas from a feed port into a closed space in a reaction chamber.

[0108] The pressure regulator and the temperature regulator are connected to the reaction chamber;
