Description

  The present invention relates to a distiller that extracts a condensed extract containing a component by condensing a vapor containing the component in an object.

  A distillation apparatus for extracting a condensed extract containing a component by condensing the vapor containing the component in the object, wherein an internal space for generating or introducing the vapor is formed and opened upward A container having an opening, an upper lid configured to close the opening from above and having a dome-shaped condensing surface facing the internal space through the opening when the opening is closed, and condensing at the condensing surface And a collecting part for collecting the condensed extract flowing down, an annular placing part is formed on the peripheral side of the opening in the container, and a lower part of the upper lid is provided with the placing part described above. A distiller is known that is formed in an annular shape in a bottom view so as to follow an annular circumferential direction and has a contact surface that is placed in contact with the placement portion.

  The distiller having such a configuration has the merit that the amount of steam flowing out to the outside can be reduced by the contact between the contact surface and the mounting portion, and the condensed extract can be efficiently collected. When the condensed extract enters between the mounting portion, there is a problem that the airtightness is excessively increased, the temperature rises, and the vapor is difficult to condense on the condensation surface.

  In order to improve such a problem, a distiller in which the abutting surface is inclined downward toward the center of the ring is known (for example, see Patent Document 1).

  According to the distiller of the above-mentioned document, the inclination of the contact surface suppresses the condensed extract between the contact surface and the mounting portion to some extent, while the surface tension causes a certain amount of condensation. Since the extract flows between the contact surface and the placement portion, further measures are required.

It is. The distiller 1 shown in FIGS. 1 to 4 includes a container 2 having an opening 2a above and an upper lid 3 that closes the opening 2a of the container 2.

  The container 2 is a ceramic. This container 2 has a bottomed cylindrical shape that is formed in a cylindrical shape that extends in the vertical direction so as to have a steam chamber (internal space) 1a that generates steam containing components in the object P such as plants. Portion 4, flange portion 7 formed integrally with bottom portion 6 of tubular portion 4 and extending radially outward from the lower end side of the outer peripheral surface of tubular portion 4, and opening portion of tubular portion 4 A collecting groove (collecting portion) 8 having a circular ring shape in a plan view formed over the entire circumferential direction is provided on the inner peripheral surface side on the 2a side.

  One or a plurality (in the illustrated example, a plurality) of introduction holes 6 a are formed in the bottom portion 6. The introduction holes 6a are a plurality of types of holes having different sizes, and in the illustrated example, a plurality of introduction holes 6a having a large size and introduction holes 6a having a small size are formed.

  The outer shape of the flange portion 7 is formed in a circular shape in plan view. The container 1 is installed above the supply container B by placing the integrally formed bottom part 6 and flange part 7 on the annular upper end edge of the supply container B such as a pan. During the installation, the container 1 can be installed above the supply container B having a large size by the flange portion 6.

  The water vapor generated by heating and boiling the water W in the supply container B is supplied to the steam chamber 1a of the container 2 through the introduction hole 6a.

  The collection groove 8 is a circular shape that is integrally formed so as to project obliquely upward from the opening 2 a side of the inner peripheral surface of the cylindrical portion 4 toward the radially inner side, and has a flat cross-sectional shape that has the same center as the cylindrical portion 4. Are formed by the outer peripheral surface of the collecting side wall portion 9 and the inner peripheral surface of the cylindrical portion 4. In the illustrated example, the upper end of the annular collection side wall portion 9 is formed at a position lower than the upper end of the cylindrical portion 4, but it may be formed at a higher position.

  The peripheral wall of the cylindrical portion 4 is formed so that the thickness of the portion other than the upper portion thereof is equal or substantially equal, while the upper portion is formed so that the thickness gradually decreases upward. And the upper end where the thickness of the cylindrical part 4 becomes the thinnest comprises the mounting part 11 which makes | forms circular annular shape by planar view.

  By the way, the mounting portion 11 is formed with a notch-shaped exhaust portion 11a uniformly at predetermined intervals in the circumferential direction (in this example, at regular intervals, and more specifically, every quarter turn). ing.

  The upper lid 3 is a ceramic. The upper lid 3 is formed in a circular ring shape in a plan view, and is bulged upward toward the center side, and the four sides of the dome part 12 from the lower end side having the maximum diameter of the dome part 12 It is configured by integrally forming a cylindrical tubular portion 13 protruding upward so as to surround it.

  A condensing surface 14 is formed on the entire inner surface of the dome portion 12 so as to face the internal space 1a of the container 2 through the opening 2a. The inside of the dome portion 12 rises from the vapor chamber 1a through the opening 2a. It becomes the condensation chamber 1b which condenses the said vapor | steam which comes.

  The cylindrical portion 13 is open at the top. Between the inner peripheral surface of this cylindrical part and the outer peripheral surface of the dome part 12, the accommodation space 1c which accommodates the cooling water C or ice is formed. The condensation of the steam is promoted by cooling the condensation surface 14 with the cooling water C in the housing space 1c.

  Incidentally, in a state where the upper lid 3 is installed above the container 2, the dome portion 12 and the cylindrical portion 13 of the upper lid 3 and the cylindrical portion 4 of the container 2 are on the same axis.

  Next, the structure in which the upper lid 3 is installed above the container 2 will be described in detail. The lower end side and the outer peripheral edge side of the upper lid 3 are in contact with the annular mounting portion 11 over the entire circumference or substantially the entire circumference. As described above, the contact surface 16 formed in a circular ring shape having the same center as that of the mounting portion in a bottom view is integrally formed. That is, the abutment surface 16 is formed such that its full length direction is in the circumferential direction of the upper lid 3, and its width direction is set in the radial direction of the upper lid 3.

  The contact surface 16 is inclined downward toward the center side (inner side) of its own circular shape. More specifically, the contact surface 16 is formed in a truncated cone shape whose diameter decreases downward. In other words, the inclination of the contact surface 16 is formed in a straight line in a sectional view, and is not curved or bent in a concave shape or a convex shape.

  A midway portion in the width direction of the contact surface 16 becomes a contact portion with the mounting portion 11. An inner regulating portion 12a that protrudes downward is integrally formed on the end side located inward of the contact portion in the width direction of the contact surface 16, and an outer side that protrudes downward also on the end side positioned on the outer side. The restricting portion 13a is integrally formed.

  The inner regulating portion 12a is formed in a circular ring shape along the entire circumference of the contact surface 16 when viewed from the bottom, and constitutes the lower end portion of the dome portion 12. The inner peripheral surface of the inner restricting portion 12a constitutes the lower end portion of the condensing surface 14, and the outer peripheral surface is formed in the vertical direction. The inner restricting portion 12a is formed thinner than the other portions of the dome portion 12.

  Incidentally, the collection groove 8 described above is disposed and formed immediately below the lower end of the inner regulating portion 12a (the lower end of the condensation surface 14).

  The outer restricting portion 13 a is configured by extending a circular annular lower end portion below the width direction outer end of the contact surface 16 in a plan view of the tubular portion 13. In other words, the outer restricting portion 13 a constitutes the lower end portion of the tubular portion 13. The inner peripheral surface and the outer peripheral surface of the outer restricting portion 13a rise in the vertical direction.

  Next, based on FIG. 1 thru | or FIG. 4, the distillation method using this distiller 1 is demonstrated.

  A container 2 is set above a supply container B in which a predetermined amount of water W is stored, and a predetermined amount of an object P such as a plant is disposed on the upper surface (bottom surface) of the bottom 6 of the container 2. An upper lid 3 is installed above the container 2 so as to close 2a.

  Subsequently, the water vapor generated by boiling the water by heating the supply container B is introduced into the steam chamber 1a from the plurality of introduction holes 6a. The water vapor in the vapor chamber 1a becomes a vapor containing the components of the object P in the process of passing through the object P placed on the bottom 6. This vapor passes through the opening 2a and rises to the condensation chamber 1b.

  The steam introduced into the condensing chamber 1b contacts the condensing surface 14 and is condensed to become a condensed extract E containing the component of the object P. During the condensation, the condensation surface 14 is cooled by the cooling water C or ice accommodated in the accommodation space 1c, so that the steam is efficiently liquefied. The condensed extract E thus liquefied flows down along the condensation surface 14 and is collected in the collecting groove 8.

  When the condensed extract E is collected in the collecting groove 8, the inner restricting portion 12a restricts the flow toward the contact surface 16 side. Further, the small amount of the condensed extract E that has flowed to the contact surface 16 is also restricted from flowing outward in the width direction of the contact surface 16 due to the inclination of the contact surface 16. When the condensed extract E seals the gap between the contact surface 16 and the mounting portion 11, the pressure and temperature of the condensing chamber 1 b and the steam chamber 1 a rise, and it becomes difficult for the steam to condense on the condensing surface 14. Although the recovery efficiency of E is lowered, the above regulation prevents the reduction of the recovery efficiency.

  In addition, when the upper lid 3 is installed on the upper side of the container 2 and in contact with the contact surface 16 and the mounting portion 11, the above-described exhaust portion 11 a is located between the contact surface 16 and the mounting portion 11. The steam in the internal space 1b is exhausted from the exhaust part 11a to the outside. By the exhaust action of the exhaust part 11a, the steam chamber 1a and the condensation chamber 1b are prevented from rising to a predetermined pressure or more by steam.

  Furthermore, the outer peripheral surface of the cylindrical part 13 is condensed by the cooling water C in the accommodation space 1c, and water droplets adhere to the outer peripheral surface. This water droplet flows down along the outer peripheral surface of the cylindrical portion 13 by its own weight. If the flowing water droplets flow toward the contact surface 16 side, they flow down inward along the contact surface 16 along the above-described inclination, and between the contact surface 16 and the mounting portion 11. And passes through the gap 11 or the exhaust part 11a and flows into the collecting groove 8 to reduce the component concentration of the object P contained in the condensed extract E, thereby reducing the quality of the condensed extract E. However, since the flow of water droplets caused by condensation on the outer surface of the tubular portion 13 toward the contact surface 16 is regulated by the outer regulating portion 13a, the quality of the condensed extract E is prevented from being deteriorated.

  Incidentally, the condensed extract E in the collecting groove 8 is collected from a collecting hole 4a drilled radially outward from the bottom side of the collecting groove 8, or by a collecting pipe 17 inserted through the collecting hole 4a. Collected.

  Moreover, when the temperature of the cooling water C in the accommodation space 1c rises, the low-temperature cooling water C is newly poured into the accommodation space 1c. At this time, the old cooling water C whose temperature has risen is from the drain hole 13b drilled in the upper part of the cylindrical portion 13 from the inner peripheral surface to the outer peripheral surface, or from the drain pipe 18 inserted into the drain hole 13b. Drained.

  According to the distiller 1 configured as described above, high-quality condensed extract E can be efficiently collected by steam distillation.

  In addition, as shown by the phantom line in FIG. 1, by putting the object P together with the water in the supply container B and boiling this water, the steam containing the components in the object P is supplied on the supply container B side. The steam may be generated and introduced into the steam chamber 1a through the introduction hole 6a.

  Moreover, although the exhaust part 11a is provided with two or more in the example to show in figure, it is good also considering the number as one. In addition, the notch-shaped exhaust part 11a may be formed in a notch groove shape that extends from the upper part of the collecting side wall part 9 to the upper part (mounting part 11) of the cylindrical part 4 through the collecting groove 8.

  Next, based on FIG. 5, a different point from the above-mentioned form is demonstrated about another embodiment of this invention.

  FIG. 5 is an enlarged cross-sectional view of a main part according to another embodiment of the present invention. In the above embodiment, the lower end of the inner restricting portion 12a is formed at a position higher than the lower end of the outer restricting portion 13a. However, in the form shown in FIG. The restricting portion 12a extends downward.
