Description

Automated in-line extraction of cypress oil to increase sterilization effect {Automated in-line extraction of cypress oil to increase sterilization effect}

The present invention relates to an automated device for extracting cypress oil to increase the sterilization effect, and more specifically, to increase the purity of limonene and esters of terpenes to increase the natural sterilization, disinfection, and antibacterial effects of cypress oil, from washing cypress tree raw materials. This is about an automated cypress oil extraction device that allows in-line PH (acidity) testing until the final extraction process.

The cypress tree is a representative tree that contains a large amount of phytoncide, which is attracting the most attention among natural antibacterial substances. In particular, the cypress leaves contain a large amount of phytoncide. Phytoncide is a natural antibiotic substance produced by trees to protect themselves from pests and pathogens, and its main ingredient is an organic compound called terpene.

Phytoncide has the effect of purifying and sterilizing the air, so it is not only good for treating various infectious diseases and atopic dermatitis, but also has less anxiety about the safety of the human body compared to synthetic antibacterial agents, so various functional products using phytoncide for deodorization, antibacterial, and sterilization are being released. .

The main components of phytoncide oil (essential oil) extracted from cypress trees consist of terpenes, of which monoterpenes and sesquiterpenes are the main components. These terpenes are hydrocarbons (C5H8)n and have sterilizing and anti-inflammatory effects. Among the oil components, limonene is widely used as a natural sterilizer and pesticide for household use. In addition, esters including terpene alcohols and acids have been shown to have sterilizing, disinfecting, and sedative effects.

To extract phytoncide from the cypress tree, steam distillation is mainly used. Since cypress oil is not soluble in water, the condensate from which the essential oil components of the cypress tree are evaporated by water vapor is used at a temperature lower than the boiling point (150℃~350℃) of the essential oil components. By cooling, you can obtain cypress oil whose composition has not changed.

Meanwhile, in relation to the method of extracting cypress oil from the cypress tree, published patent 2015-0046526 (cypress extract extracted by steam and compressed air and processed product manufactured by adding the cypress extract), published patent 2014-0008906 (cypress extract using cypress tree) A number of prior patents have been proposed, such as phytoncide extraction method), published patent 2012-0047039 (apparatus for extracting essential oil from cypress tree leaves), and published patent 2012-0050318 (apparatus for extracting phytoncide essential oil from cypress tree by low-pressure steam distillation). .

However, the cypress oil extract using the conventional steam distillation method and prior patents is extracted due to various factors such as uneven composition of the cypress tree raw material itself required for extraction, extraction temperature during the extraction process, change in cooling temperature, inflow of impurities, and volatilization of phytoncide. The content of phytoncide components in cypress oil varies depending on the process used, making it difficult to produce cypress oil with uniform purity.

Korean Patent No. 2105797 “Cypress oil extraction device and extraction method” (registered on April 22, 2020)

The present invention is an invention made to solve the problems of the prior art, and the acidity (PH) value of the cypress oil in distilled water is automatically measured at the steam stage containing the cypress oil component in the distillation tank. By obtaining information and comparing it with the acidity value of the actual cypress oil coming out of the oil-water separator, if the appropriate acidity is not reached in the distillation steam state, additional cypress wood raw materials connected in-line are added and a stirring blade created in the distillation tank is used. The purpose is to provide an automated system that can extract cypress oil with uniform acidity by adjusting and adjusting the acidity value required for the final cypress oil from the distilled steam state through additional acidity value adjustment work.

In order to increase the purity of limonene and esters of terpenes to increase the natural sterilization, disinfection, and antibacterial effects of cypress oil, the automated device for in-line extraction of cypress oil to increase the sterilization effect according to the present invention is a bubble washing device and washing device for cleaning cypress leaves.

An acidity measurement unit that measures and a central control device that automatically adjusts the amount of cypress leaves added, stirring conditions, and steam supply pressure according to the acidity value of the acidity meter; It is characterized as an automated device system that performs an in-line continuous process from washing cypress leaves to extracting cypress oil.

In addition, when the acidity measurement value is not reached, the acidity value is adjusted by automatically adding additional cypress wood raw materials, adjusting the stirring rpm using a stirring blade, and controlling the steam supply amount. In order to maintain uniform purity of cypress oil, the acidity value is adjusted. It is characterized by being composed of an automated device capable of continuous in-line processing from washing to distillation tank input and oil-water separator extraction.

The present invention can extract cypress oil of uniform purity through acidity measurement and self-adjustment to have a constant acidity in the steam stage containing phytoncide components in the distillation tank, and fundamentally blocks the inflow of external impurities through a continuous in-line process. , the entire extraction process is controlled by an automated system, which is effective in extracting cypress oil with guaranteed uniform purity.

As shown in the drawing, the automated device for in-line extraction of cypress oil according to the present invention includes a distillation tank (10), a stirring device (20), a steam device (30), a bubble washing device (40), a cypress leaf cutting device (50), and an in-line device. It is roughly divided into the following components: cypress leaf injection device (60), cooler (70), oil/water separator (80), central control device (90), and acidity (PH) control device (12) (81).

In more detail, the automated device for in-line extraction of cypress oil to increase the sterilization effect according to the present invention includes a bubble washing device (40) for cleaning cypress leaves, and an in-line cypress leaf injection device (60) for cutting the washed raw materials and simultaneously inserting them into the distillation tank. ), a stirring device 20 inside the distillation tank 10, a steam device 30 for supplying steam into the inside of the distillation tank 10, real-time acidity of distilled water and cypress oil inside the distillation tank 10 Acidity measurement unit 12 that measures; and a central control device (90) that automatically adjusts the amount of cypress leaves input, stirring conditions, and steam supply pressure according to the acidity value of the acidity meter. It is an automated device system that performs an in-line continuous process from washing cypress leaves to extracting cypress oil.

In order to increase the purity of limonene and esters of terpenes to increase the natural sterilization, disinfection, and antibacterial effects of cypress oil, the automated device for in-line extraction of cypress oil to increase the sterilization effect according to the present invention is

washing cypress leaves using bubbles; Cutting the washed raw materials and simultaneously putting them into a distillation tank; Supplying high-temperature steam and stirring stirrers inside the tank using a heating means; Measuring and adjusting the pH (acidity) of steam containing cypress oil components in a distillation tank; Converting water vapor whose PH (acidity) value is confirmed into condensate by a cooler; An oil separation and extraction step of separating the condensate into cypress oil and cypress sap liquid; Extract cypress oil of uniform purity using a method including.

The distillation tank 10 is a means of extracting mixed steam containing essential oil components of cypress leaves by steam distillation. Cut cypress leaves are placed on an internal separator and connected to a steam device 31 on the side to produce high temperature. High-temperature, high-pressure steam is supplied to the steam jacket 11, which consists of a double jacket coupled to the distillation tank 10, through the steam supply pipe 31 and the steam pressure control valve 32, and the steam is supplied from the distillation tank. The acidity of the evaporated water vapor is measured through the acidity meter (12), and when the optimal acidity is confirmed, the evaporated water vapor is converted into condensate by the cooler (70), and the cypress oil and cypress water are mixed through the oil-water separator (80). Separate and extract each. When the water vapor containing cypress oil to increase the sterilization effect is confirmed to have a uniform acidity value, the central control device 90 automatically opens and closes the pressure reducing control valve 71 connected to the cooler to achieve uniform acidity and sterilization ability. Allows oil extraction.

Here, the acidity of the cypress oil produced through the final oil-water separator to increase the sterilization effect was found to exhibit uniform sterilization, antibacterial, and deodorizing effects when the pH value was 4.0 or less, as a result of various experiments by the present applicant.

In addition, the acidity value of the water vapor inside the distillation tank is large when compared to the cypress oil because the water vapor exists in the form of cypress water evaporated with cypress oil. As a result of various experiments by the applicant, the pH of the water vapor in the distillation tank is When the value was 6.5 or less, the PH value of the final cypress oil showed a value of 3.9 to 4.0.

The pure acidity value of cypress oil is pH 2.64, which is highly acidic, and the sesquiterpene content is found to be 19.20%. However, when extracted using the actual steam distillation method, the pH value ranges from 2.6 to 2.6 due to the mixing of impurities and the influence of temperature and pressure during extraction. It has a non-uniform acidity value of up to 6. Due to this non-uniform acidity value, the sterilizing, deodorizing, and antibacterial properties of phytoncide oil mixed with purified water vary from product to product, leading to consumer dissatisfaction and making it difficult to use as a sterilizing product.

First, the cypress tree leaves are washed with a bubble cleaning device (40) using a water washing method using bubbles, and then automatically transferred to a cutter (50) connected to the bubble cleaning device and cut to a selected size (3 to 5 cm). Cypress leaves are continuously in-line fed into the distillation tank (10) through the leaf injection device (60). At this time, in order to increase the extraction amount of the cypress leaves and reduce the extraction time, they are introduced into the distillation chamber in a preheated state by contacting the high temperature plate part 62. The temperature of the high-temperature plate top is maintained at 60°C to 70°C to allow the cypress leaves to preheat efficiently.

The cypress leaf injection device is controlled by the central control device 90 and performs automatic injection. When the cut cypress leaves are introduced through the cypress mouth injection part 64, the transfer pipe opening and closing part 67 opens, and the pressure piston opens. As the cypress leaves are transferred to the high-temperature plate portion (62) through (65), a fixed amount can be input into the distillation tank through the transfer pipe opening/closing valve (63) connected to the distillation tank (10).

Meanwhile, if the cypress tree leaves are washed through a bubble washing process, the loss of phytoncide oil contained in the cypress tree leaves is minimized, and the amount of cypress oil extracted is increased through physical activation of the cypress tree leaves.

Next, high-pressure steam is supplied to the distillation chamber through a double-layered steam jacket (11). The high-pressure steam is controlled through the steam pressure control valve 32 and then supplied to the steam jacket. It is possible to extract high-purity cypress oil that maintains its unique color through indirect heating with a double steam jacket. As steam is supplied, automatic stirring is performed using the stirrer 20 inside the distillation tank, and the RPM is automatically adjusted according to the purity of the extracted cypress oil. Experimental results showed that the optimal RPM is 10 to 40 RPM.

In addition, the stirrer 20 is composed of a double blade structure 22 to increase stirring efficiency, and the lower stirring blade has a wedge-shaped structure and a structure 23 capable of moving up and down 180 degrees to physically impact the surface of the cypress leaf. The amount of cypress oil extracted can be increased.

Next, the acidity of the distilled water evaporated by the supplied high-temperature, high-pressure indirect steam is monitored in real time through the acidity meter 12, and when the set optimal acidity value is reached, the pressure reducing control valve (automatically connected to the cooler) is monitored. 71) is opened and moved to the cooler 70 to be cooled and condensed. The cooler is formed with a downward slope (3 to 5 degrees) in the condensate discharge direction, and the condensed water is supplied to the oil-water separator 80 by its own weight.

When the PH value monitored by the acidity meter 12 does not reach the set value, the central control device 90 additionally supplies cypress leaves through the cypress leaf injection device 60, and uses the stirrer 20 and Distilled water can be moved to the cooler (70) only when the PH value set through the control of the steam pressure control valve (32) is reached, so that cypress oil with uniform purity and sterilization efficiency can be manufactured.

As an example, the central control device 90 maintains the acidity value of the cypress oil below PH4 and automatically opens the pressure reducing control valve 71 connected to the cooler to move it to the cooler 70 and cool and condense it.

In addition, the cypress leaf injection device 60 is opened and closed periodically according to the acidity value measured in real time through the central control device 90, and cypress oil with uniform acidity is extracted through the injection of additional cypress leaves. .

In addition, the cypress distilled water extracted by the steam distillation method is separated into cypress oil and cypress water through a condensate oil-water separator (80) and stored.

The acidity of the actually extracted cypress oil is checked through the acidity meter 81 mounted on the cypress oil storage part of the oil-water separator 80, and measured by comparison with the acidity of the distilled water installed in the distillation tank 10. By adjusting the acidity value of the distilled water, uniform extraction of cypress oil is possible to increase the sterilization effect.

Meanwhile, cypress oil and cypress water extracted through the above process can be used to make various deodorant, antibacterial, and air purifier products with uniform purity and sterilizing, deodorizing, and antibacterial effects.

In explaining the present invention above, an automatic cypress oil in-line extraction system for increasing sterilization effect having a specific shape and structure has been described with reference to the accompanying drawings. However, the present invention can be modified and modified in various ways by those skilled in the art. Such modifications and changes should be construed as falling within the scope of protection of the present invention.
