The present invention relates to the copper condensing unit for the distilling machine, more particularly, to a hydrogen sulfide adsorption distiller using copper that can easily adsorb and remove hydrogen sulfide (H2S) from fermented liquor by a copper condensing unit for distilling machine.
Generally, an alcoholic drink is a beverage containing alcohol, and generally refers to a beverage containing 1% or more of alcohol.
Alcohol is broadly divided into fermented wine, distilled liquor, and compounded liquor, depending on the production method or the alcohol content.
The fermented liquid is an alcoholic drink in which diastase, which is a starch saccharifying enzyme, and yeast, which is a fermenting agent, are acted on sugar contained in fruits, that is, starch-contained grains converted to sugars, and fermented. The fermented liquid contains a lower alcoholic content of about 8 to 14 degrees depending on the sugar content of the raw material or the type of fermenting yeast, and beer and wine belong to this category.
Distilled liquor is made by distilling a fermented wine to obtain a higher percentage of alcohol from fermented wine, whiskey, brandy, rum, gin, vodka, tequila, and soju belong to this category. It usually contains alcohol of 40 percent or more.
Distilled soju, which is a type of distilled liquor, is obtained by mixing starch-containing raw materials with ipguk and water, then, fermenting, and distilling. As a raw material for distilled soju, starch-rich grains such as rice, barley and corn, and root and tuber crops such as potatoes and sweet potatoes are used. Among them, sweet potatoes contain beta-carotene, which is a precursor of vitamin A, and thus exhibit anti-cancer properties, and also contain high-quality dietary fibre and Alaafin, and thus exhibit constipation-relieving action. Further, it contains a large number of other minerals such as potassium and calcium and various vitamins and thus is mainly used as a raw material for distilled soju.
During the production of distilled spirits, the distilled liquor is obtained from vaporizing the fermented alcohol by heating and condensing the vaporized alcohol through cooling in a reverse way. As described above, fermented wine is made by fermenting fruits or grains. Solid components of fruits and grains other than alcohol still remain in the fermented wine, If the fermented wine is heated directly, the solid component could be burned and adhered to the heating surface, and then, the burnt smell is coming out tasted from the distilled spirit.
In addition, if harmful gases contained in the fermented liquid are removed from the liquid effectively, mellow and better-quality distilled spirits can be produced. A typical harmful gas is hydrogen sulfide.
As shown in
A cooling vessel 14 containing cooling water C is located on the upper part of the second chamber 12, wherein the vaporized alcohol is reached in the second chamber 12 would be cooled by cooling water C and condensed in the lower part of the cooling vessel 14 to be liquefied.
At this same time, the liquefied alcohol is the distilled liquor B and drained outside through a drain tube 13 along the wall surface of the distillation vessel 10.
However, such a conventional distiller heats the wine (A) through a heat source F directly, which is hard to control the distilling temperature of the wine, and the material of the vessel is not copper. Therefore, some of the solid particles are burned and adsorbed on the inner surface of the first chamber inside 11, burnt flavour could be coming out from the distilled liquor B. In addition, it has the disadvantage of not being able to get rid of hydrogen sulfide and should be a lower quality of the distilled liquor, it has a disadvantage in that liquid quality has deteriorated.
The present invention has been proposed to solve the problems in consideration of the various problems of the prior arts, and the object of the present invention is to provide the copper condensing unit for the distilling machine in which vaporization is facilitated more, and at the same time, hydrogen sulfide of the vaporized alcohol and the condensed liquefied alcohol is adsorbed with copper by catalytic reaction, and thus, hydrogen sulfide, which affects the organoleptic flavour properties of the distilled liquor C in a negative way, should be removed as much as possible, then, the quality of the liquor is improved.

Distilled liquor is an alcoholic beverage made by distilling the primary fermented wine to obtain a higher alcohol percentage than a fermented wine. Distillation is the process of obtaining high-concentration alcohol by using the difference in the boiling points between alcohol and water. When the fermented wine is heated slowly, the alcohol with a lower boiling point evaporates earlier than water. By collecting and cooling the evaporating vapours or gases such as steam, a high-concentration alcoholic liquid can be obtained in the end.
Referring to
That is, the heating vessel 100 and the storage vessel 160 are preferably formed of stainless steel or steel.
The retention tube 120, the vertical tube 130, the spiral coil 132, the cooling vessel 140 and a water catchment vessel 150 are preferably formed of pure copper, which is easy to be catalyzed so as to facilitate adsorption and removal of hydrogen sulfide of vaporized alcohol and condensed liquefied alcohol.
At this time, the retention tube 120 is formed in the form of a fallopian tube whose passage becomes narrower from the lower part to the upper part, whereby once the alcohol vaporized in the heating vessel 100 escaped through the vent hole 112 of the vessel lid 110, it is not passing through quick by the hole of the upper formed cone from the lower part opened of the retention tube 120, and while the hydrogen sulfide of the alcohol vaporized temporal staying in 120 is primarily adsorbed and removed on the inside surface of the wall of retention tube 120 formed of pure copper having a catalytic reaction.
The vertical tube 130 and the spiral coil 132 fitted and fixed to the internal hole of the vertical tube 130 form a spiral passage to minimize interference with the ascending current of the vaporized alcohol while increasing the contact area of copper with the vaporized alcohol passing through from the retention tube 120. Therefore, while the vaporized alcohol up current rises and passes through, hydrogen sulfide of the vaporized alcohol is secondarily adsorbed and removed on the inside (inner) surface of the vertical tube 130 and the surface of the spiral coil 132 formed of pure copper have a catalytic reaction as well.
The cooling vessel 140 has an open upper part to store the cooling water B and can close the opening with a vessel lid to enhance the cooling effect, if necessary.
The submerged part 142 for protruding from the centre bottom of the cooling vessel 140 is preferably opened to the outside downward with respect to the center of the bottom of the cooling vessel 140, and protrudes vertically up to a certain height inside the bottom, so as to be submerged in the cooling water B, and free space is preferably formed through the submerged part 142 so that the outer peripheral surface and the upper end of the vertical tube 130 do not come into contact with each other.
At this time, the upper end of the submerged part 142 is upside down to the lower part while vaporized alcohol passing through the upper part of the vertical tube 130 is guided by the upper part of the submerged part 142 and dispersed to all directions, and at the same time, it is preferably formed in a hemispherical shape protruding upward so as to come into contact with the inside surface of the submerged part 142 to do heat exchange.
The edge of the lower end of the submerged part 142 preferably forms dripping part 144 that protrudes downward lower than the bottom height of the cooling vessel 140, for the condensed liquefied alcohol dripping along the inside of the submerged part 142 make sure to flow down into the collecting vessel 150.
The collecting tray 150 is coupled around the lower outer peripheral surface of the vertical tuber 130 so as to surround the lower opening edge of the submerged part 142, and the drain (discharge) tube 152 is preferably installed at the side of the bottom of the liquid collecting tray 150 to drain the condensed liquefied alcohol to the receiver vessel 160 for storing the distilled liquor C.
In this manner, a hydrogen sulfide adsorption distiller using pure copper of the present invention has advantages in that, while alcohol vaporized in a heating vessel 100 sequentially passes through a retention tube 120, which is formed of pure copper having a catalytic reaction, a vertical tube 130, a spiral coil 132, a cooling vessel 140, and a liquid collecting tray 150 until distilled liquor C of condensed liquefied alcohol is completed, vaporization process is facilitated, and at the same time, hydrogen sulfide of the vaporized alcohol and the condensed liquefied alcohol is adsorbed, and thus, hydrogen sulfide, which affects the organoleptic flavour properties of distilled liquor C negatively, is removed as much as possible, thus improving liquor quality.
