摘要： PURPOSE:To provide a method for more simply and economically improving an aroma and a flavor of a leaf tobacco raw material and obtain the leaf tobacco raw material improved in the aroma and flavor. CONSTITUTION:This method for improving an aroma and a flavor of a leaf tobacco raw material is to seal two kinds of leaf tobacco raw materials 20 and 21 in a treating tank 19, then close valves 23 and 26, subsequently inject carbon dioxide from a tank 11 through heat exchangers 15 and 17 into the treating tank 19 with a pump 16, keep the carbon dioxide at 0-50 deg.C temperature, feed the carbon dioxide to the treating tank 19 until the interior thereof is pressurized to 35-100kg/cm , maintain the interior of the treating tank 19 in a state of an interior thereof increased to a prescribed pressure for 10-60min, thereby leach a flavor ingredient contained in cells in the interior of the leaf tobacco raw materials 20 and 21 into the carbon dioxide, then close a valve 18, open the valve 23, slowly reduce the pressure in the interior of the treating tank 19 to atmospheric one, thereby condense the flavor ingredient dissolved in the carbon dioxide onto the surface of the leaf tobacco raw materials 20 and 21.

摘要： PURPOSE:To produce an inclusion compound having high inclusion ratio of guest component with a smaller amount of carbon dioxide consumed than a conventional method. CONSTITUTION:As a first process, a guest and a host components are prepacked into an inclusion tank 15, as a second process, carbon dioxide is introduced into the inclusion tank 15 under pressure and the guest component is dissolved to form a saturated dissolution phase of the guest component. As a third process, a stirrer 16 is operated, the saturated dissolution phase is brought into contact with the host component in the inclusion tank 15 while controlling temperature to include the guest component in the host component. In the first process, an excessive amount of the guest component is packed into the inclusion tank 15 so that an undissolved guest component remains after the saturated dissolution phase is formed by the second process.

摘要： PURPOSE:To obtain a method and a device for controlling the contact interface position of a pressure vessel, which can maintain the height of the contact interface between the fluid to be treated and the supercritical fluid inside of the pressure vessel constant. CONSTITUTION:A laser beam at a width of X is made incident upon the fluid 27 to be treated and the supercritical fluid 28 to measure damping factors A, B of the laser beam, which is transmitted through the fluid 27 to be treated and the supercritical fluid 28. Next, a damping factor C1 of the laser beam at the time when the laser beam is made incident upon the fluid 27 to be treated or the super critical fluid 28 at a desired position is measured. A reference value C2 of the damping factor C1 in the case where the existence of the contact interface at a reference position separated from the upper end of the laser beam, which is positioned at a desired position, with a distance Y in the vertical direction is assumed is computed with an equation (1). In the case where the damping factor C1 is smaller than the reference value C2, supply quantity of the fluid 27 to be treated is made excessive, and in the case where the damping factor C1 is larger than the reference value C2, discharge quantity is made excessive to maintain the contact interface at the reference position. Reference value C2=A(1-Y/X)+B(Y/X)...(1).

摘要： PURPOSE:To suppress foaming at the time of recovering the raffinate and to continuously and stably extract a supercritical gas by keeping the raffinate introduced into a second separator at a high pressure to prevent rapid foaming in the separator, heating the raffinate stably at a temp. where the raffinate is not degraded and separating the gas dissolved in the raffinate. CONSTITUTION:A foamable liq. material (e.g. honey) is introduced into an extractor 1, and supercritical CO2 is introduced into the extrator 1 and brought into contact with the material to extract the desired substance in the material in CO2. CO2 incorporating the extract is introduced into a first separator 2. The raffinate in the extractor 1 is kept above the pressure where the liq. material begins to foam and introduced into a second separator 3 heated to a temp. where the raffinate is not degraded and the gas dissolved in the raffinate is separated. The raffinate is heated and retained for a specified time in the second separator 3, the gas dissolved in the raffinate is separated and discharged, and the extractant after gas separation is discharged into the atmosphere.

摘要： PURPOSE:To provide a method for extracting soluble substance of a natural solid raw material, which enhances extraction efficiency and dispenses with after-drying step of the natural solid raw material after extraction treatment. CONSTITUTION:High-pressure fluid is passed through a natural solid raw material to extract a specified component. In the method for extracting soluble substance, the high-pressure fluid is hydrated to the saturation amount of dissolution at a first temperature in a water tank 8 and then heated at a second temperature higher than the first temperature. Thereby the ratio of relative moisture of the high-pressure fluid is diminished. The high-pressure fluid diminished in the ratio of relative moisture is allowed to flow through the raw material of a tobacoo in an extraction vessel 1. Thereby nicotine is extracted from the raw material of the tabacoo.

摘要： PURPOSE:To provide the subject simpler and more economical method for improving smoking flavor, and to obtain a leaf tobacco stock improved in smoking flavor. CONSTITUTION:A treatment tank 19 is first encapsulated with a leaf tobacco stock. Second, valves 22, 26 are closed. Then the treatment tank 19 is injected with carbon dioxide by a pump 16 from a tank 11 via heat exchangers 15, 17. The temperature of the carbon dioxide stands at 0-50 deg.C. The carbon dioxide is fed until the inside of the tank 19 is pressurized to a level of 35-100kg/cm . At this specified elevated pressure level, the tank 19 is maintained for 10-60min. As a result, the flavor ingredient in the cells inside the leaf tobacco stock 20 is leached into the carbon dioxide. Then, a valve 18 is closed, the valve 22 or 26 is opened to gradually decrease the pressure inside the tank 19 to the atmospheric pressure. Thereby the flavor ingredient dissolved in the carbon dioxide is condensed on the surface of the leaf tobacco stock 20. The flavor ingredient is localized on the surface of the leaf tobacco stock 20 by this method.

摘要： PURPOSE:To selectively extract and separate a specific component from a natural solid raw material and also to easily and properly control the content of the specific component and water in the natural solid raw material after treatment. CONSTITUTION:High pressure carbon dioxide is brought into contact with a tobacco raw material housed in a extractor 11 to dissolve and extract nicotine contained in the tobacco raw material into the high pressure carbon dioxide. Next, the high pressure carbon dioxide contg. the extracted nicotine is brought into contact with absorbing water 18 housed in an absorber 17 to absorb the nicotine. Then, the high pressure carbon dioxide from which the nicotine has been absorbed is again returned to the extractor 11 and circulated. Here, the inside of the extractor 11 is set in a pressure range of 200 to 300kg/cm and in a temperature range of 50 to 80 deg.C, and the inside temperature of the absorber 17 is set in a range of 40-60 deg.C. The relative ratio of the water content to the high pressure carbon dioxide at extraction is set in the range of 55-80%.

摘要： PURPOSE:To prevent pulsation in high pressure fluid such as aqueous carbon dioxide with the use of a highly durable equipment while preventing impurity from entering the high pressure fluid in a super critical fluid chromatograph separating device or the like. CONSTITUTION:A metal cover plate 12 is fixed to a metal container body 11 so as to form a pressure container which serves as an accumulator 1. A temperature sensor 14 is pivotally fitted into the container body 1 through the cover plate 12 at the center of the latter. A heater 15 is laid around a cylindrical part 11a of the container body 1. A connecting pipe 13 is communicated with a pipe line through which a high pressure fluid flows, so that the high pressure fluid is led into the container body 1 through the connecting pipe 3. The container body 1 is heated while the temperature of the interior of the container body 1 is monitored so as to gasify (evaporate) the high pressure fluid in the container body 1, thereby pulsation in the high pressure fluid flowing through the pipe line may be absorbed through this elasticity of this gas.
