Abstract

PURPOSE:To perform extraction in an extremely efficient manner, by propagating the vibration of a container to an extractant and material to be extracted filling said container as repetition of compression and expansion. CONSTITUTION:When a vibration generating source 9 is operated by a drive motor to vibrate a container 3, the vibration in the inner wall surface of said container 3 is propagated to the material to be extracted and an extractant (a) filling the interior thereof as a repetition of compression and expansion, and the liquid level of the extractant (a) is rippled thereby. The effect influenced on the material to be extracted is just similar to such that a water-containing sponge is compressed and expanded; it is really pref. transfer the material to be extracted contained in the solid into the extractant. As the result, in the extracting experiment of a herb medicine, the extraction can be completed in an extracting time of about 1/2-1/3 as compared to a conventional simple extractor with a stirrer.

Description

Detailed Description of the Invention The present invention provides extremely efficient extraction by propagating vibrations of an extractor, more specifically a container, to the extracting agent and extract material filled in the container as a repeated phenomenon of compression and expansion. Regarding the extraction machine that can.

Extraction in which the extract in the extract is transferred to the extractant is widely used in many industrial fields in the form of solid-liquid or liquid-liquid extraction. For example, in pharmaceutical factories and food factories, active ingredients are extracted from solid natural products as solid-liquid, and in chemical factories, components that cannot be separated by distillation are extracted as liquid-liquid based on the difference in solubility.

Conventionally, various machines and devices have been used for such extraction. The simplest method is to perform solid-liquid extraction by filling a container with the extraction material and extracting agent and leaving it as is or stirring it with an attached stirrer. There are still methods, such as the case of extracting soybean oil, in which solid-liquid extraction is carried out by bringing the extractant into countercurrent contact with each other while transporting the extractant using a screw. Furthermore, there is also a liquid-liquid extraction method in which a heavy liquid is supplied from the upper part and a light liquid is supplied from the lower part using a formal apparatus such as a spray tower, a perforated plate extraction tower, or a rotating plate type extraction tower with stirring.

However, these conventional extractors have the drawback that the extractant and extractant are not continuously activated, resulting in poor extraction efficiency. In other words, in the case of the above-mentioned solid-liquid extraction, even if the extractant and extractant are stirred or brought into countercurrent contact, the movement of the extract inside the extract is static movement, and the movement takes time. There is.

In addition, in the case of liquid-liquid extraction mentioned above, the main mass transfer occurs when bubbles in either liquid collapse or generate due to the action of a perforated plate, rotating plate, etc., so when there is no such action, there is almost no mass transfer. What a waste of time.

As a result of intensive research into a new extractor that eliminates the drawbacks of the conventional slanted extractor, the present inventor found that when vibration is applied to a container, the vibration is influenced by the amplitude and frequency of the vibration. It is believed that the repeated phenomenon of compression and expansion is propagated to the extracted material and extractant, and that this repeated phenomenon continuously activates the extracted material and extractant, resulting in extremely efficient extraction. This discovery led to the completion of the present invention.

Hereinafter, the configuration of the present invention will be explained in detail based on the drawings, but the present invention is not limited to these, such as the shape of the container.

FIG. 1 is a side view showing one embodiment of the present invention, and FIG. 2 is a sectional view taken along the line A--A in FIG. 1, including the state of use. The container 3 consists of a main body 1 with a U-shaped cross section and a slightly long body, and a lid 2 screwed to the main body 1 at each flange portion. 7 (not shown) is supported on a base 8, and a vibration generating source 9 connected to a drive motor (not shown) is attached to the container 3.

The drawing shows an example of batchwise solid-liquid extraction, but when the vibration source 9 is activated by a drive motor (not shown) to vibrate the container 3, vibrations on the inner wall surface of the container 3 or vibrations caused by the filling inside the container 3 occur. It is propagated to the extracted material and extracted material a as a repeated phenomenon of compression and expansion. In such a repeated phenomenon, the period and degree of compression/expansion are affected by the frequency and amplitude of vibration of the container 3 caused by the vibration source 9, and this can be clearly confirmed, for example, by simply inserting a hand into the extracted liquid in the container 3. However, due to this phenomenon, the liquid surface of the extractant exhibits ripples, and the state this gives to the extractant is similar to compressing and expanding a sponge containing water, and the extraction inside the solid extractor. It is very suitable for transferring the quality into the extractant for extraction.

Since this example is a batch method, the extractant must be replaced once the extract concentration in the extract reaches the equilibrium solubility. Compared to this, the extraction time can be completed in about 1/2 to 1/3.

FIG. 3 is a side view showing another embodiment of the present invention. A vertical cylindrical container 11 containing a plurality of perforated plates 10 is mounted on a base 16 using elastic springs 12, 13, 14, 15.
The container 11 is supported by vibration generating sources 17 to 22 connected to a drive motor (not shown).

The drawing shows an example of continuous liquid-liquid extraction, in which the container 11 is vibrated to supply light liquid from the bottom and heavy liquid from the top, as in the case of the previous embodiment. When both liquids are brought into countercurrent contact with each other, the light liquid rises in the form of bubbles through the heavy liquid and becomes fine particles at the perforated plate, and the bubbles repeat splitting and gathering between the perforated plates, further changing their shape. A constantly changing state is also observed.

According to this example, the tower height is 1
The same extraction efficiency can be obtained at around /20
