ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a home-style decoctor and a method of preparing red ginseng extract using the same. More particularly, this invention pertains to a home-style decoctor endowed with steamy boiling function, the decoctor heating and boiling (undried, white or red) ginseng to draw out red ginseng extract, the invention further applying to a method of preparing red ginseng extract.
BACKGROUND OF THE INVENTION
Generally speaking, Panax ginseng is a medicinal herb used as hematinic tonic medicine for a long time in the eastern Asia. Korean ginseng is especially known to contain a great quantity of more than thirty kinds of ginsenoside.
Grubbed up after the cultivation of four to six years, panax ginseng is classified into undried (unprocessed and containing water as much as 70 to 80%), white (the primarily processed product), and finally red ginseng according to the processing method.
White ginseng is made by being dried with or without the skin of undried ginseng of over four years, the white containing water below 12%. Red ginseng is manufactured by steam-boiling undried ginseng for the purpose of long-time preservation or according to another process.
The red ginseng has several kinds of phenolic compounds and maltol, aging-resistants (anti-oxidants), and ginsenosides Rg and Rh, all of which are produced through a steamy boiling process but not contained in undried ginseng, as well as a great volume of more than thirty kinds of ginsenoside. The red ginseng is known to further have a great quantity of ginsenosides, its peculiar components, and panaxydol group and panaxytriol group.
Red ginseng made as above may be produced as ginseng extract, which is drawn out with several components of red ginseng. The extract can be drunk as a undiluted solution or an alkaline which is made by adding raw medicinal stuff or physiological activator thereto.
It is difficult to domestically make red ginseng extract because of several complicated processes as described above. Even though it is made domestically, charcoal is used to decoct the red ginseng, which is also not simple. Because of those problems, there has been developed a decoctor for facilitating the domestic decoction of ginseng or other objects.

is a vertical section of a conventional home-style decoctor;
FIG. 2
is an enlarged vertical section of the heating vessel of the conventional decoctor; and
FIG. 3
is an enlarged vertical section of the steam condensing means of the decoctor.
Referring to
FIGS. 1
,
2
and
3
, a prior art decoctor
10
has: a main body
20
equipped with a heater
22
at an appropriate place; a heating vessel
30
which stores water and is heated by heater
22
; a filter
32
positioned in heating vessel
30
and for containing an object to be boiled (for instance, undried, white or red ginseng); a steam collector
40
for gathering steam generated from heating vessel
30
during the decoction of the object; means for cooling steam collector
40
with cooling water; and steam/condensed water guiding means for enabling heating vessel
30
to communicate with steam collector
40
when heating vessel
30
is safely placed in main body
20
, and thus leading the steam contained in heating vessel
30
to steam collector
40
and the condensed water condensed in steam collector
40
to heating vessel
30
.
With the conventional home-style decoctor
10
, when heater
22
is operated while heating vessel
30
containing an object to be boiled and a predetermined amount of water is mounted thereon, the to-be-boiled object contained in heating vessel
30
is decocted due to heater
22
heated. This to-be-boiled object is heated while immersed in water stored in heating vessel
30
. The steam produced in heating vessel
30
during the decoction goes into steam collector
40
by means of the steam guiding means, and the steam collected in steam collector
40
and then condensed by the cooling means in turn to heating vessel through steam/condensed water guiding means
50
.
The decoction of a to-be-boiled object and its extraction is carried out through the repeated performance of incoming of the steam produced from heating vessel
30
, which is heated, into steam collector
40
and heating vessel
30
in the form of steam or condensed water.
In case of red ginseng extraction through the decoction of undried or white ginseng with the conventional home-style decoctor, however, the undried or white ginseng is designed to be decocted while immersed into water stored in the heating vessel. In this condition several kinds of phenolic compounds and maltol as aging-resistants (anti-oxidants) and ginsenosides Rg and Rh are not produced, which are, however, contained only in red ginseng. This is because there is no steamy boiling in the conventional decoctor.
SUMMARY OF THE INVENTION
Therefore, in order to overcome such drawbacks of the prior art, an objective of the present invention is to provide a home-style decoctor endowed with a steamy boiling function, with which ginseng (undried or white) is steam-boiled to become red ginseng and thus generate several kinds of phenolic compounds and maltol, aging-resistants (anti-oxidants), and ginsenosides Rg and Rh. This invention also aims for a method of preparing a red ginseng extract using the decoctor of the invention.
To accomplish the objectives of the present invention, there is provided a home-style decoctor endowed with steamy boiling function, the decoctor being comprised of: a main body of a predetermined size equipped with a heater at an appropriate position of the bottom; a heating vessel for containing and heating a predetermined amount of water with the heater; a support plate having a plurality of throughholes and for allowing a to-be-boiled object to be placed above the surface of water stored in the heating vessel and to be steam-boiled with the steam produced inside the heating vessel; means for supplying water for boiling into the heating vessel so that the to-be-object is immersed after its steamy boiling and drying; a steam collector for gathering steam produced when the to-be-boiled object is decocted with water for boiling poured in the heating vessel which stores the water for boiling through the water for boiling supplying means; means for condensing the steam collected into the steam collector; and steam/condensed water guiding means for causing the heating vessel to communicate with the steam collector when the heating vessel is safely placed. in the main body and thus leading the steam present in the heating vessel to the steam collector and the condensed water placed in the steam collector to the heating vessel.
There is provided another embodiment of a home-style decoctor endowed with steamy boiling function of the present invention comprising: a main body of a predetermined size having a heater at an appropriate place of its bottom; a heating vessel put above the heater for heating a to-be-boiled object contained therein; a support plate having a plurality of throughholes mounted on the heater for supporting a to-be-boiled object so that it is located above water stored, the plate allowing the object to be steam-boiled by means of steam produced inside the heating vessel; a water reservoir installed at an appropriate place of the main body for storing water to be supplied to the heating vessel; means for supplying water stored in the water reservoir to the heating vessel; a steam collector for gathering steam produced from the heating vessel while the object contained in the heating vessel is boiled; means for condensing the steam collected in the steam collector; and steam/condensed water guiding means for enabling the heating vessel to communicate with the steam collector when the heating vessel is safely placed in the main body, and thus leading the steam contained in the heating vessel to the steam collector and the water condensed in the steam collector to the heating vessel.
For another aspect of the present invention, there is provided a method of preparing red ginseng extract using a home-style
