[The purpose of the device]

 Plants, especially the leaves of coniferous trees such as pine needles and cedar leaves, emit a gaseous aromatic substance called phytoncide, which is considered to be an active ingredient during so-called forest bathing. In order to separate and extract the phytoncide mainly contained in the leaf part of this plant, the leaves of the coniferous tree, which was previously considered to contain a relatively large amount of phytoncide, were finely cut in a room with good airtightness. , The gas around it was collected by a collector. However, when this conventional method was used, the collection efficiency was very poor, and it was a great disadvantage economically.

The present inventor has conducted earnest research to economically and efficiently extract and extract phytoncide from a plant. As a result, the source plant containing phytoncide is housed in a closed container, and steam is applied to the source plant. The inventors have found that phytoncide can be efficiently extracted from these and have completed the device of the present invention. Therefore, an object of the present invention is to provide a phytoncide extractor capable of economically and efficiently separating and extracting phytoncide, which is known as an active ingredient in a forest bath, from a raw material plant.

Phytoncide is considered to be an active ingredient in forest bathing as described above, but it is generated by the plant to secure its own territory, in other words, to stop the growth of the partner. According to this idea, phytoncide is adsorbed on a porous adsorbent to allow the phytoncide to diffuse over a relatively long period of time, and the picked fruits and The effect of maintaining the freshness of vegetables, etc. is considered to be great, and the separation and extraction of phytoncide from the raw material plant is extremely important in this respect as well.

FIG. 1 is an explanatory view showing an embodiment of the phytoncide extracting apparatus of the present invention, FIG. 2 is an explanatory view showing another embodiment of the phytoncide extracting apparatus of the present invention, and FIG. 3 is a further embodiment of the phytoncide extracting apparatus of the present invention. FIG.

In the figure, 1 is a closed container, and 2 is a raw material plant filled in the closed container 1. It is needless to say that the airtight container 1 is provided with an openable / closable airtight lid for loading and unloading the raw material plant 2, which is not particularly shown. Reference numeral 3 denotes a steam blow-out pipe as a steam supply means attached to the lower portion of the closed container 1. Reference numeral 4 denotes a boiler that sends steam to the steam blow-out pipe 3, and the steam generated in the boiler 4 is supplied from the steam blow-out pipe 3 into the closed container 1 through the steam supply pipe 5. In the embodiment shown in FIG. 1, no special partition is provided in the closed container 1, and the raw material plant 2 in the closed container 1 is placed directly on the upper surface of the steam outlet pipe 3. ing.

Next, 6 is an air supply pipe connected to an appropriate place in the upper part of the closed container 1, and the gaseous phytoncide vaporized from the raw material plant 2 by the steam supplied from the steam outlet pipe 3 is sent to this air supply pipe. It is accommodated in the next-stage accommodation cylinder 7 through the trachea 6. Reference numeral 8 in the drawing denotes a valve attached in the conduit of the air supply pipe 6.

In this embodiment, when the steam is supplied from the boiler 4 to the lower part in the closed container 1 through the steam supply pipe 5 and the steam outlet pipe 3, the steam becomes an upward flow and the raw material plant 2 The phytoncides contained in the raw material plant 2 are evenly contacted and steamed out. Then, phytoncide, which is a gaseous aromatic substance separated from the raw material plant 2, is collected in the storage cylinder 7 through the air pipe 6. Although not shown, a vacuum generator or the like may be attached to the accommodating cylinder 7 so that the inside of the cylinder is in a negative pressure state so that the phytoncide can be recovered smoothly. From the beginning of the work, phytoncides with a low vapor content and a relatively high concentration can be recovered, but the recovery rate of phytoncide decreases with the passage of time and the vapor content increases, so the required time After a lapse of time, the valve 8 attached in the pipeline of the air supply pipe 6 is closed, and the operation of the boiler 4 is stopped. By such an operation, the container cylinder 7 is filled with phytoncide having a high concentration.

Next, in the embodiment shown in FIG. 2, the airtight container 1 containing the raw material plant 2 is divided into upper and lower parts by a partition member 9 such as an air-permeable metal net or a perforated plate, and the upper part is made into a raw material plant. The second storage chamber 10 and the lower part thereof are the steam generation chambers 11. In this embodiment, the equipment of the boiler 4 is unnecessary.
