Abstract

PURPOSE: Provided is a process for extracting natural volatile essential oil alleviating blood pressure from Japanese cypress by a vertical type heating system. CONSTITUTION: The natural essential oil is extracted from branches and leaves of the Japanese cypress by the vertical type heating system. The essential oil extraction time is shortened by supplying high temperature and high pressure steam to a high pressure steam line of an outer casing of a distillation tank and increasing the inside temperature rapidly. And the production efficiency is increased by bypassing the high pressure steam and passing through a low pressure steam line and recycling a residual essential oil component after extracting.

Description

Distillation method of Japanese Cypress (Chamaecyparis obtusa essential oil alleviating against blood pressure by promoted heating system)

The present invention is composed of volatile monoterpene, sesquiterpene, and mixtures of derivatives thereof, which are harmless to the human body from the branches and leaves of the planting by-product, Chamaecyparis obtusa Sieb. Et Zucc, English Japanese cypress or Hinoki cypress. The present invention relates to a method for extracting a natural essential oil (organic compound) by a specially manufactured vertical type heating promotion system (Fig. 1).

Essential oils are produced mainly in plants, but are usually present in the cavities of plants, either in the mammary gland or in the gland or dissolved in resin, most of which are flowers, buds, leaves, and branches of seed plants. It is derived from each part of the plant, stem, root, etc. The composition varies according to the type of plant. Very important in terms of

Volatile essential oils are a type of antibiotic that plants emit to protect themselves from the surrounding microbes. However, antibiotics have a double side that kills the germs that are about to be killed immediately, and their vitality kills the germs that are beneficial to the body. The good thing about volatile essential oils is that they can focus on what kind of bacteria to kill because of their nature, they are absorbed smoothly by the human body, and they are not chemically synthesized. In addition to having a strong antibacterial activity, essential oils provide various functions to our humans, including odor elimination, stress relief, relaxation, hookworm, diuresis, expectoration, tonic, anti-inflammatory and pleasant effects. In addition, children with autism and seniors suffering from depression have confidence and activeness, and have a special effect on women's skin beauty. Recently, a health law called "forest therapy" is being carried out in Germany, Russia, Japan, etc., which is intended to expect a calming and calming effect of the mind by entering the forest and drinking the fragrance of trees.

Essential oils, which are fragrant components of trees, are used for various purposes and are currently dependent on imports. Usually, there is an aroma or odor as a liquid insoluble in water and soluble in organic solvents. Most of them are lighter than water, but some of them are heavier than water, such as sperm oil and cinnamon oil, with specific gravity ranging from 0.7 to 1.07. It is liquid at room temperature, but when it cools, crystals are precipitated. The crystals are called stearoptene, and the part that is not crystallized is called oleoptene. The boiling point is usually in the range of 150 to 350. Essential oils are fragrances and are used in various fragrances, food additives, deodorants, food flavors, fruit essences, cosmetic perfumes, air fresheners, and the like. In addition, there are medicinal, industrial, flotation oil (floatation oil) and the like.

Since most of essential oils are insoluble in water, the steam distillation method is the simplest and most widely used method in which the fragrance component is not changed by the heat of steam. Since the total pressure of the insoluble mixture vapors is equal to the sum of the vapor pressures of the respective pure components, when the sum of the vapor pressure of the essential oil and the vapor pressure of the water is equal to the pressure in the distillation tank, the essential oil boils out with water vapor. Since it can flow out at a temperature much lower than the boiling point of the essential oil components (150 to 350), there is little concern about decomposition or deterioration of the components. However, there is a risk of missing the head space early in the steam distillation. Ross oil and orange flower oil contain water-soluble components, so the water-soluble components move to water during steam distillation. In general, the rose water refers to this water. Leaves, stems and roots should be dried immediately after harvesting or about 1/3 to 1/4 of the weight, and the branches, stems, and roots of the wood should be crushed finely with a cutting machine. It is then generally extracted with a horizontal type steam distillation extraction equipment.

Extraction using the general horizontal extraction equipment as described above has the advantage of easy raw material input to the distillation tank, but has a big disadvantage that the extraction efficiency is lowered per unit time due to the limited amount of raw material input, heat transfer time to the input raw material It takes a long time, and there is a risk of missing the head space early in the steam distillation. Therefore, the heat transfer to input materials is required to be fast and constant, and as a result, there is a problem that a subtle difference may occur in the quality of the refined oil that is produced.

The present invention has been devised in view of the above problems, by using a vertical heating promotion system to shorten the heat transfer time and extraction time to the feedstock to increase the economics, while maintaining a constant blood pressure relief effect produced The purpose of the present invention is to provide an extraction method for improving the quality of the protein.

The essential oil extraction method of the present apparatus for achieving the above object is to prepare a raw wood powder for extracting vegetable essential oil and load the raw wood powder crushed to a certain size in a fine stainless basket to supply to the distillation tank using a hoist Supplying steam of a high temperature and high pressure to heat the raw wood powder filled in the distillation tank in a short time to the steam heating line mounted in the inner and outer cases of the distillation tank, wherein the raw wood powder in the distillation tank is hot steam Rapidly and completely volatilizes even essential oil components that are difficult to extract with a conventional extraction device by rapidly heating with internal steam, and the inside of the distillation tank through an automatic steam control valve installed at the steam outlet of the distillation tank. The oil vapor in the oil refinery Class step of, due to the cooling water which is circulated inside the condenser by a cooling tower and a cooling water circulation pump the water vapor supplied to the condenser is condensed and is characterized in that it comprises the step of separating the pure essential oil and effluent by the water separator.

Here, to maintain the temperature inside the distillation tank at a low temperature of 105 ~ 110 ℃ to obtain a high quality essential oil, and thus a lot of extraction time can be drastically shortened without deterioration of the quality, raw material powder in the distillation tank It is possible to dramatically increase the extraction efficiency of essential oils by extracting even the high boiling point essential oil components contained in the raw materials by rapidly raising the temperature to a certain temperature.

The efficacy of essential oils extracted in this process is characterized by a higher tendency to lower mean arterial pressure compared to the control group, even if the rats are inhaled in the vaporized state without significant mean arterial blood pressure change.

Hereinafter, an extraction method of the present vegetable essential oil extraction device will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view for explaining the extraction method of the present invention. When the configuration of the drawings is described, the system is composed of the following three systems.

1. Transfer and supply of raw wood powder and post-processing device

2. Steam supply system and refinery and effluent treatment system generated after extraction

3. Steam generation It consists of boiler fuel supply device, high pressure steam supply condensate recovery device and water supply device.

Referring to the first system, the branches or branches produced by thinning or pruning the cypress are pulverized with sawdust of about 3 mm or less using a wood mill (7), and then lined through a wood powder feed fan (8). It transfers to the wood powder feed hopper 9 through 40. From the loaded hopper is supplied the necessary amount to the wood flour loading basket (2) consisting of a fine stainless steel net of 100 microns or less downward. The loaded wood powder is moved to the upper part of the distillation tank 1 using the hoist 10, and then the upper lid 35 of the distillation tank is opened and the wood powder is loaded into the distillation tank 1 with the wood powder loaded in the loading basket 2. do. After this process, the lid 35 of the distillation tank is closed, and the air control valve 42 of the air compressor 21 is opened and supplied to the lid to completely maintain airtightness. After the essential oil extraction, wait for the pressure in the distillation tank (1) to be equal to the atmospheric pressure to lock the air control valve 42 and discharge the air in the lid to open the upper lid (35). The hoist 10 again lifts the wood powder stacking basket 2 and moves it to the by-product treatment hopper 20. The extraction residue poured into the bottom with a large amount of water is used after fermentation after dehydration treatment.

Referring to the second system, the steam of about 9 bar generated from the steam boiler 14 passes through the pressure reducing valve 31 installed at the outlet of the boiler and is decompressed to about 6 bar and is sent to the steam distributor 15. 6 bar of water vapor supplied to the steam distributor is supplied to the outer casing high-pressure steam line 32 of the distillation tank (1) serves to quickly increase the temperature of the raw wood powder already introduced into the distillation tank (1). Again, the high pressure steam line (6 bar) is supplied with 1 bar of low pressure steam through the pressure reducing valve 33 through the bottom of the distillation tank (1) to the inside of the distillation tank so that other components, including the essential oil components contained in the raw wood flour, from the bottom Volatilized by the supplied steam, this steam containing essential oil is sent to the cooler (3). At this time, the water vapor discharged from the distillation tank (1) is adjusted in conjunction with the pressure sensor 41 for checking the internal pressure of the distillation tank (1) by the flow control valve 34 and adjusts the internal pressure of the distillation tank 1 bar or The steam passage is adjusted to maintain the pressure at which pressure is reached and the steam is transferred to the cooler (3). At this time, since the cooling water supplied from the cooling tower 11 is already circulated inside the cooler 3, water vapor containing the essential oil component passing through the cooler 3 is condensed through heat exchange in the cooler 3, and the condensed water Is collected in the oil / water separator (4). At this time, in the oil / water separator 4, an oil component lighter than water floats on the upper layer and is collected and sent to the refinery storage tank 5, and the effluent separated in the lower layer is drained and stored in the effluent storage tank 26.

Usually, the refined oil of low purity takes a little longer to separate, but the purified oil extracted from this device can be separated within 1 minute in oil / water separator (4). Transfer it to a cool dark place.

In consideration of the amount of oil refined separated from the oil water separator (4) and steam consumption, if the extraction of the essential oil is almost finished, the low pressure steam supply valve (36) is closed and bypasses the high pressure steam (6 bar) and the low pressure steam (1 bar). The valve 37 is opened and the high pressure steam is supplied through the low pressure steam line of the distillation tank 1 to blow water vapor containing the residual essential oil into the cooler 3. Next, after the bypass valve 37 is closed, when the internal pressure of the distillation tank reaches atmospheric pressure, the lid of the distillation tank 35 is opened and the wood powder loading basket 2 is lifted. After cleaning the inside of the distillation tank (1) and repeat the above process. Separate refined oil and effluent are stored in separate storage tanks for use.

The third system receives the fuel of the boiler from the diesel storage tank 13 and operates the steam boiler 14 to operate at a commercial pressure of 9 bar. The generated water vapor is cooled and recovered through the above-described process of 2., stored in the condensate recovery tank, and then supplied to the boiler. All of the supplied low pressure water vapor is condensed by passing through the cooler (3), the essential oil is separated, recovered in the effluent state, and stored for a long time. Recovering and using the supplied steam is more economical than generating steam by supplying ordinary cold water to the steam boiler, but this device is not recoverable because all the steam discharged is used as refinery or effluent.

Therefore, in view of energy saving, the coolant passing through the cooler 3 is thought to be a high temperature, and the hot water passing through the cooler is supplied to the line from the water supply pressure tank 16 to the cooling tower 11 to use the boiler 14 as supply water. The water supply valve 43 is installed and the electric bypass valve 39 is installed in the hot water line 38 passing through the cooler 3 so as to interlock with the electric flow control valve 40 on the cooling tower 11 side to supply the feed water. Supply. The recovered hot water is transferred to the condensate tank 17 and recycled into the steam generation supply water of the boiler 14. In addition, it is also used as a replenishment water supplied to the distillation tank (1) is a very preferred method in terms of energy saving.

On the other hand, in order to use the essential oil recovered in the oil and water separator (4) for a proper use it must go through a certain ripening period to minimize the deterioration of essential oil components by storing in a cool dark place. The effluent recovered in the oil / water separator 4 is removed in the short-term effluent storage tank 6 to remove some deposits and then transferred to the long-term storage tank for stabilization. After a certain period of time, the runoff is stabilized and used for a separate purpose.

Hereinafter, the effect on the blood pressure of the essential oil extracted by the present invention will be described in more detail by examples.

<Example 1> Effect on blood pressure of essential oils

Cycling essential oil was obtained using the extractor described above, and experimental animals purchased ICR mice and SD rats to adjust to the new environment for one week before the experiment in the breeding room. Immediately before the start of the experiment, the mice weighed 30 ml / g at 6 weeks of age and the rats were 220 ± 20 g at 8 weeks of age. The room temperature was 23 ℃ and the lighting was 150-300 Lux for 12 hours. Solid feed and tap water were freely fed.

After the catheter was attached to the femoral artery of the rat one day before the experiment, the average arterial blood pressure was measured using Escort II (DUBS, USA). Five rats were placed in each group and the vaporized essential oil was inhaled for 2 hours. Immediately before inhalation, 0 minutes were taken and measured for 2 hours at 15 minute intervals. The results of various experiments were compared to the group without the essential oil treatment and the change was analyzed by Student's t-test or x2-test. Significance assays were performed when the p-value was less than 5% compared to the control.

Experimental results to see if the test substance affects the blood pressure of the normal rat appeared as shown in FIG. When the blood pressure changes over two hours while inhaling essential oils were measured at 15-minute intervals, the cypressic oils, like other essential oils, tended to reduce overall arterial blood pressure.

As described above, the use of this heating promotion system to extract essential oils from plants produces not only very high quality essential oils, including head space components, but also extraction compared to other pressurized horizontal extraction devices currently used in Korea. The time can be shortened by about 1 hour or more. Therefore, this has the effect of increasing the oil refining yield by about 20%, which has the advantage of reducing the cost of producing and selling the oil and improving the competitiveness by supplying high quality oil.

In addition, since the extraction process is carried out at a relatively low temperature, by minimizing the alteration of the components, the intrinsic efficacy of essential oils, such as antimicrobial activity, as well as the homogeneous function of maintaining the blood pressure relieving effect identified in the present invention as well. It is characterized by the ability to produce essential oils.
