| 1. | A distillation apparatus including a base container to contain the liquid to be distilled, a cooling liquid container mounted above the base container adapted to receive a cooling liquid vapour tube extending upwardly from the base container passing upwardly through the cooling liquid container and connected to a condensing spiral passing downwardly through the cooling liquid container to a spout extending away from the apparatus. |
| 2. | A distillation apparatus as defined in claim 1 wherein the cooling liquid container is removable from the base container to permit access to the interior of the base container. |
| 3. | A distillation apparatus as defined in claim 2 wherein the cooling liquid container and vapour tube are mounted on a removable lid on the base container, the vapour tube extending through the removable lid. |
| 4. | A distillation apparatus as defined in either claim 1 or claim 2, whereinthe base container has a pressure relief valve positioned in an upper portion of a wall of the base container. |
| 5. | A distillation apparatus as defined in any one of the preceding claims, wherein the cooling chamber has a lid and a spout wherein the upper chamber can be filled and emptied. |
| 6. | A distillation apparatus as defined in any one of a heat source such as an electric hot plate or gas burner to heat the liquid in the base container. |
| 7. | A distillation apparatus as defined in any one of the preceding claims 1 to 6 wherein the spout extends away from the apparatus to permit the distillate to be discharged into a receptacle distant from a heat source heating the liquid in the base container. |
It is often desired to have available a pure liquid obtained by distillation. One example of this is the requirement for distilled water in the home, often for medical purposes. Also other liquids are often distilled to obtain the more volatile factions of the base liquid. Thus wine or other alcoholic liquids can be distilled to obtain the alcohol.
It is an object of this invention to provide a distillation apparatus to be used by families or business persons to provide the distillate in a few minutes.
A further object of the invention is to provide an apparatus which is economical to produce and also quick and easy to use.
Thus there is provided according to the invention a distillation apparatus including a base container to contain the liquid to be distilled, a cooling liquid container mounted above the base container, adapted to receive cooling liquid, a vapour tube from the base container passing upwardly through the cooling liquid container connected to a condensing spiral passing downwardly through the cooling liquid container to a spout extending away from the apparatus.
Preferably an insulating tube surrounds the vapour tube.
In order to more fully describe the invention reference will now be made to the accompanying drawing showing one form of the invention in cross section.
The distillation apparatus has a base pot 1 to receive the liquid to be distilled. The pot 1 has a screw cap 2 to which is attached a tube 3 integral with a condensing chamber 4. Within the tube 3 is a vapour tube 5 passing upwardly to a downwardly extending condensing spiral 6 leading to an outlet spout 7 through the bottom of the condensing chamber 4.
The condensing chamber has a lid 8 and a spout 9 so that the condensing chamber can be filled and emptied.
The base pot 1 has a safety relief valve 10. This embodiment of the invention is intended to be heated by placing on a hot plate or other heated surface, and to evenly distribute the heat the base of the pot is provided with a heat diffuser 11.
The lid 8 of the condensing chamber preferably has air holes 12.
Thus in operation the condensing chamber 4 is unscrewed from the pot 1 and the liquid to be distilled is placed in the pot. On replacement of the condensing chamber the cooling liquid, usually water or chilled water or water containing ice is placed in the condensing chamber. The apparatus is then placed on a hot plate.
The vapour produced on heating or boiling passes up the vapour tube protected by the insulating tube to be condensed in the downwardly extending serpentine and discharged through the outlet spout. This spout is of a length to have its outlet at a sufficient distance from the hot plate.
Thus if an alcoholic liquid such as wine is distilled the volatile alcohol will vaporise and be condensed to pass through the outlet. It will be realised that the apparatus can also distil other liquids such as water.
Although the apparatus as described is placed on a hot plate it is to be realised the pot can have incorporated in its base an electric element for heating purposes.
Although various forms of the invention have been described in some detail it is to be realised the invention is not to be limited thereto but can include variations and modifications falling within the spirit and scope of the invention
