Vegetable Terpene Tablets for Extracting Essential Terpene Oil It relates to an extraction method.

In recent years, many people are developing various natural therapies and new leisure to protect their health from the increasingly serious urban pollution. Among them, forest baths, which let you breathe fresh air in the forest and relax your mind and body, are gaining attention as a new health therapy among the city residents. The effects of forest baths known at home and abroad to date include bactericidal action, antioxidant action, stress relieving action, deodorizing action, and human emotional engineering sedation by fragrance emission. In addition, the forest bath not only provides these functional effects, but also gives the child with autism and the elderly suffering from depression not only the confidence and aggressiveness of the central nervous system, but also stimulates the cerebral cortex to increase concentration and momentum, and the skin of humans. It is known to have a special effect on beauty. These effects are mainly due to volatile terpene essential oils, ie, organic chemical fragrance substances emitted by conifers, fragrances and plants. These terpene essential oils have cosmetics, pharmaceuticals, quasi-drugs, hygiene products, textiles, household chemicals, home appliances, building materials, paints, pigments, deodorizing products, foods and animal feeds due to their inherent functionality. It is applied to the functionalization of related products, and also used in so-called aromatherapy, which treats diseases by mitigating the autonomic nervous system by activating the body's physiological function as humans contact and inhale fragrance substances on the skin. As such, terpene essential oils that are released from plants and beneficial to humans and of great industrial value are generally proportional to the essential oil content of the plants. That is, plants with a high essential oil content also have a large amount of release of fragrance components. Such essential oils are called, for example, "natural aromatic oil substances possessed by plants," which are usually composed of dozens or hundreds of compounds. It is a kind of hydrocarbon produced by the gathering of many isoprene (Isoprene, C5H8), mainly composed of monoterpene, sesquiterpene, diterpene and aromatic and aliphatic compounds, among which the terpene compound is the most abundant.

On the other hand, the terpene essential oil is known to be contained mainly in the conifers such as pine, pine, cypress, birches, and the like and aroma and plants such as tangerine and tanza. In addition, the terpene oil content of the plant reaches a very small amount of 5%, and varies slightly depending on the season and species. Thus, since terpene essential oil contains a small amount in a plant, a predetermined terpene essential oil extracting apparatus is required in order to extract from a plant.

As an example, a method of extracting essential oil using a portable steaming method of a small essential oil extractor used by the Korean Forestry Research Institute will be described. First, the branches or leaves cut to about 1cm in length are put in a distillation tank in a separately manufactured stainless steel net. Put water in the distillation tank so that the sample will not be submerged, connect the cooling water to the cooler, and ignite. Subsequently, the refined oil flowing out while heating for 2 to 3 hours after the internal temperature of the distillation tank reaches 100 degreeC is collected in a rectifier collector. At this time, terpene essential oil is lighter than water, so it floats on the water. If it is collected in a separatory filter and left for 20 minutes, it is divided into an essential oil layer and a water layer. Then, you only have to discard the water and collect only the essential oils. The essential oil collected by repeating this process several times is filtered to remove impurities contained in the essential oil. Finally, about 1% of anhydrous sodium sulfate (drying at 105 DEG C for at least 3 hours and cooling in a desiccator) of the essential oil weight is added thereto, and purified terpene essential oil is obtained by dehydrating for 24 hours in a cold dark place.

However, in the case of extracting the essential oil in the above manner, the oil recovery amount (OilRecovery Percentage) is not only a small amount, but a lot of work time is required in the process, there is an economic problem that increases the cost accordingly. In addition, when the material is put in a small distillation tank and boiled by the so-called distillation method, since the active ingredient inherent in essential oils is extracted from the water vapor after being dissolved in a large amount of water, there is a problem in yield, that is, mass production is difficult.

The present invention has been made to solve the above problems, an object of the present invention is to provide a high-purity natural vegetable terpene essential oil extraction method newly designed to mass-produce terpene essential oil at a low cost and time.

Meanwhile, referring again to FIG. 1, an auxiliary condensate discharge path 490 having a plurality of condensate discharge pipes 493 is connected downstream of the main valve 451 of the main condensate discharge path 450.

In addition, referring to Figure 5, a pair of main guide rail 270 provided in the pressure tank 200 as a raw material input means for injecting the raw material of the vegetable terpene essential oil into the pressure tank 200, and the perforated network for raw material storage A container 810, a container stacker 830, and a transport cart 850 are provided. The perforated network container 810 has a case-type structure in which a plurality of steam passing holes 811 are formed. The perforated net container 810 is stacked up and down on the shelf portion 833 of the container holder 830. The paper stack 830 is movably positioned on the auxiliary guide rail 853 of the transport cart 850. Accordingly, the paper stock holder 830 may be moved along each guide rail 853 and 270 to be introduced into the pressure tank 200.

Meanwhile, the method for extracting vegetable terpene essential oil according to an embodiment of the present invention using the vegetable terpene essential oil extracting device having the above configuration will be described in detail with reference to FIGS. 1 to 6.

First, the ground and wood parts of several species are crushed to about 2 to 3cm to prepare a raw material of vegetable terpene essential oil (S10). The species used as the raw material is a variety of species, such as pine, pine, rigi pine, globose, larch, cedar, non-tree, cypress, birches, firs and the like. Here, the essential oil content contained in each species is different from each other, even the same species is known to be slightly different depending on the collection place and time. For example, according to the related academic papers to be described later, the terpene oil content extracted by the distillation method in the case of domestic pine tree is described as an average of about 1.08%.

On the other hand, the prepared raw material is put into the pressure tank 200 (S11). In this step, in order to inject the raw material into the pressure tank 200, it is preferable to use the raw material input means as shown in FIG. That is, in the step S11, the raw material is first accommodated in the perforated network container 810, for example, about 200 kg. Thereafter, the perforated network containers 810 containing the raw materials are loaded up and down on the container loading table 830. Then, by moving the transport cart 850 to match each guide rail 270 (853), and pushes the container carrier 830 placed in the transport cart 850 into the pressure tank 200. In this way, while the perforated net container 810 is loaded on the container loading rack 830, the entire container loading rack 830 is introduced into the pressure tank 200, whereby the raw material is easily put in and taken out. In addition, since the raw material can be evenly distributed in the space portion in the pressure tank 200, it is possible to effectively carry out essential oil extraction within a short time.

Subsequently, after the raw material is added, the tank body 210 is sealed using the door 230. Then, the vacuum pump 300 is driven to reduce the pressure inside the pressure tank 200 (S12). In the step (S12), it is preferable to reduce the pressure until the pressure in the pressure tank 200 reaches a vacuum degree of about 30 to 40 torr (torr). By reducing the pressure in the pressure tank 200 as described above, the pores of the plant cells, that is, the pores of the raw materials, are expanded, thereby increasing the extraction efficiency of the vegetable fertene essential oil from the raw materials. Subsequently, after the step S12, the steam supply means 100 is driven to generate steam (S13). That is, the boiler 130 is driven to heat the water supplied from the water tank 110 to generate steam. At this time, the steam generated in the boiler 130 is supplied to the pressure tank 200 via the steam pressure regulator 180 at a pressure of about 5kg / ㎡g (S14). While continuously supplying steam to the pressure tank 200 for a predetermined time, the temperature sensor 214 and the pressure gauge 212 measure the temperature and pressure in the pressure tank 200, and the measured data is transferred to the predetermined main control. It is determined whether the preset reference temperature and pressure have been reached (S15). Here, the temperature and pressure set for various trees can be adjusted differently within 130 ℃, the example is based on a pine tree reference temperature is about 130 ℃, the reference pressure is about 2.0kg / ㎡g desirable. The reference temperature and the reference pressure are preset in consideration of the capacity and design pressure of the pressure tank 200, it may vary depending on the design of the pressure tank 200.

On the other hand, when the temperature and pressure measured in the step (S15) does not reach the reference temperature and pressure, the steam is continuously supplied, and when the reference temperature and pressure is reached, a predetermined time set in the main control, for example, about It is determined whether about 1 hour has elapsed (S19). When the preset time has elapsed, the steam supply to the pressure tank 200 is stopped (S20). As such, the reason for stopping the steam after a predetermined time elapses is because most of the vegetable terpene essential oils contained in the raw material are extracted when the set time elapses. Therefore, while the amount of extraction of vegetable terpene essential oil can be substantially increased, a small amount of terpene essential oil is abandoned during the extraction process in consideration of production cost and time, and the amount of abandonment is only a negligible amount. . In addition, even when the steam supply is stopped, the temperature and the pressure in the pressure tank 200 are continuously checked and controlled as in the step S15.

Subsequently, the water vapor discharge port 213 of the pressure tank 200 is opened to start discharging the water vapor material in the pressure tank 200 to the heat exchange condenser 400 (S16). Here, the reason why the steam discharged from the pressure tank 200 to the heat exchange condenser 400 is referred to as “water vapor material” is because the water vapor contains vegetable terpene essential oils extracted and evaporated from the raw materials introduced into the pressure tank 200. Because it is, it is ordered to distinguish from the steam supplied from the boiler 130 to the pressure tank 200.

On the other hand, while the step (S16) is in progress, the steam is continuously supplied to the pressure tank 200 to continuously maintain the inside of the pressure tank 200 in a high temperature / high pressure state. In this process, in the raw material introduced into the pressure tank 200, the vegetable terpene essential oil contained in the raw material is extracted and volatile according to the change in the state of being maintained at a high temperature / high pressure in the vacuum state of the pressure tank 200. In other words, it is evaporated and contained in water vapor. In particular, since the hot steam is intensively injected at a high pressure toward the raw material from the injection member 250, the raw material can effectively extract the material contained in the raw material by the so-called convection steamer action. In addition, in a state in which the initial state of the pressure tank 200 is maintained at a low pressure of a vacuum degree, since high temperature / high pressure steam is supplied to the pressure tank 200, it is possible to increase the extraction effect of vegetable essential oils from raw materials and to shorten the time. There is an advantage. The step 16 lasts about 1 hour, during which time steam is continuously supplied to the pressure tank 200 to maintain the high temperature / high pressure. Therefore, the vegetable terpene essential oil is continuously extracted from the raw material in the pressure tank 200 for about 1 hour, and the extracted terpene essential oil is contained in the water vapor material and continues to move to the heat exchange condenser 400 through the water vapor discharge path 220. do.

Therefore, the heat exchange condenser 400 is cooled by the cooling means 500 and condensed by the heat exchange the water vapor material moved from the pressure tank 200 to the condensed water (S17). Specifically, the circulation pump 540 forcibly pumps the cooling water of the cooling water tank 510 to the cooling pipe 430 in the condensation tank 410 through the cooling water supply path 470, and continuously cools the cooling pipe 430. Let's do it. Then, the high temperature water vapor material introduced into the condensation tank 410 is contacted with the cooling pipe 430 to be cooled and converted into condensed water. At this time, it is preferable that the cooling water temperature supplied to the cooling pipe 430 is about 18 ° C so that the condensed water can be maintained at a temperature of about 30 ° C. To this end, the coolant in the coolant tank 510 is continuously cooled by the operation of the cooler 530. On the other hand, the cooling water warmed by heat exchange with water vapor passing through the cooling pipe 430 is recovered into the cooling water tank 510 through the cooling water discharge path 480.

The condensed water condensed in the condensation tank 410 includes water, vegetable terpene essential oils, and other moles of flotation. The condensate is discharged and stored in the oil / water separator 600 through the main condensate discharge path 450 (S18).

Meanwhile, the condensed water stored in the oil / water separator 600 is a mixture of water, terpene essential oils and foreign substances. However, since the specific gravity of water and terpene essential oils are different from each other, if the condensed water is left for a predetermined time, the essential oil layer and the water layer are naturally divided into upper and lower parts. Accordingly, after checking the boundary between the water and the terpene essential oil through the transparent window 620 of the oil / water separator 600, the terpene essential oil is opened by opening the valve 631 provided in the oil refinery discharge pipe 630 positioned above the boundary. To separate to the outside (S21). In addition, the water and foreign matter filled in the oil-water separator 600 may be discharged to the outside by opening the valve 651 installed in the water discharge pipe 650.

However, the terpene essential oil separated by the oil / water separator 600 as described above contains a very small amount of water. Therefore, the separated terpene essential oil can be purified and purified into pure natural vegetable terpene essential oil using a predetermined oil separator (not shown) (S22). Since the refinery separator is released and used in various models throughout the industry, a detailed description thereof will be omitted.

On the other hand, when the amount of condensate discharged from the heat exchange condenser 400 is small, the discharged condensate is provided in the condensate discharge path 490 so that the discharged condensate can be collected in, for example, a separatory filter or the like. The auxiliary valves 491 and 492 may be opened to discharge the condensed water into the discharge tube 493.

On the other hand, when terpene essential oil is extracted from the raw materials in the same manner as described above, when about 200 kg of raw material is put into the pressure tank 200, for example, pine nuts are extracted on average about 1.05 liters (average moisture content of about 54%) . The amount of terpene essential oil extracted from pine nuts is 1.08 ml / 100g in the case of the steaming method. (Forest of pine trees in coniferous tree essential oils) In the case of about 0.79% (v / w%), and in the 1999 Forestry Research Report, `` Development of Tree Refinement Method '', the pine tree extract averages about 0.7125 ± 0.1275% (v / w%) for 6 months. In the case of this method, the average amount of terpene oil extract of pine nuts is 1.14 ml / 100g, which is higher than that of the steaming method. Therefore, the extraction efficiency of the vegetable terpene essential oil of the terpene essential oil extraction apparatus according to an embodiment of the present invention can be very high. Such an amount of extraction is a value that is recognized as a very high extraction amount for those skilled in the art given that the amount of essential oil contained in the pine tree is very small.

In addition, the remaining oil content of the remaining unextracted may be released as a volatile component in the natural state or crushing of the raw material, and may remain in the residual water vapor in the pressure tank 200 during the extraction process or a small amount in the raw material after extraction, In addition, since the extraction operation is completed per unit time, a small amount of vegetable Tefpen oil may remain. Therefore, it can be seen that the terpene essential oil extraction method of the present application has a very high effect through the amount of terpene essential oil extracted as described above.

In addition, the so-called one-cycle working time required to input the raw material into the pressure tank 200 and separate the essential oil from the condensate water takes about 26 to 28 hours to obtain refined refined oil by the conventional steaming method. Considering that the extraction time by the method takes about 2 hours or so, there is an advantage that it can save several times more time than the conventional method. As a result, it is possible to supply low-cost vegetable terpene oil-related products according to mass production by extracting a large amount of vegetable terpene oils in a short time as well as to reduce the cost required and reliably terpene without depending on imports to related industries. There is also the advantage that the oil can be supplied.

For reference, most of the vegetable essential oils extracted as described above are composed of terpene compounds, so-called terpene essential oils. The terpene concentrations of these terpene essential oils vary greatly depending on the surrounding environment in which raw materials are produced, such as seasons and climate, as mentioned above. Myrcene, α-terpinene, limonene, etc. are the main agents, of which the highest content of α-pinene is known. In addition, referring to the study on the antimicrobial activity of coniferous conifer essential oils (Kang Ha-young, Seong-sook Lee, and In-Kyu Choi), published in the Korean Journal of Forest Energy, Vol. 13, No. 2, data on various substances contained in essential oils are disclosed. .

In addition, as described above, the use and effects of vegetable terpene essential oils extracted from conifers have been published in various papers ("Effects of forest bath components emitted by trees", "Use of essential oil components emitted by trees", "Biochemistry of tree extract components"). -"Kang Ha-young, Forestry Researcher" ("Stress Relief Effect of Essential Oils Isolated from Coniferous Species" -College of Veterinary Medicine, Chungbuk National University) Research on Antimicrobial Activity "-Forestry Researcher, Department of Forestry, Kang Ha-young, Sung-Sook Lee, In-Kyu Choi (" Ergonomic Evaluation of Sedative Effects of Pine Tree Flavor "-Chungbuk National University Institute of Industrial Science and Technology-Lim Heon-gil). In other words, the plant terpene essential oil has a wide range of biological activities such as insect repellent, insect growth inhibition and feeding inhibition, plant growth inhibition, deodorization, pharmacological action, in addition to health and recreational functions and antibacterial action. The antimicrobial properties of these essential oils have good side effects and very low residual toxicity. Therefore, active research is being conducted, and they have already been applied to perfume products such as perfumes and cosmetics. In addition, terpene essential oil is known to be effective in reducing stress. In addition, Tefpen essential oils are listed in Korea Pharmaceutical, Jang Won-ki, Korea Cosmetic Ingredients (KCID), International Cosmetic Ingredients (ICID), Food and Drug Administration (FDA).

As described above, in view of the fact that research and products are being developed and marketed in various fields of use of terpene essential oil, when using the terpene essential oil extraction method according to the embodiment of the present invention as described above, Naturally, it is expected that the extraction of a large amount of terpene oils will greatly contribute to the development of the industry related vegetable terpene oils.

As described above, according to the vegetable terpene essential oil extraction method according to an embodiment of the present invention, a large amount of natural vegetable terpene essential oil can be extracted within a short time. In addition, it is possible to increase the extraction efficiency of terpene essential oil compared with the prior art.

Therefore, by reducing the production cost by reducing the time and cost of terpene oil extraction, there is an advantage that can provide a low-cost terpene oil-related products to the general consumer.
