(a)との間に介設されたものである。As an actual supercritical extraction apparatus, the apparatus shown in FIG. 6 has been proposed as Japanese Patent Application No. 62-119956 (see Japanese Patent Laid-Open No. 63-285176). In this device, in order to improve the contact condition between the extraction medium fluid and the product to be processed (d), the treated product case (c) has a dispersion filter of the sintered body at the inflow and outflow ends of the extraction medium fluid.
(g) and (h) are annular presser lids (i) (j), mounting bolts (k), packing
It is installed by (l) and the extraction medium fluid introduced from the introduction path (e) is dispersed by the filters (g) and (h) to make even contact with the article to be treated (d) and extract. After the extraction medium fluid containing the quality component is discharged from the discharge path (f) to the outside of the vessel, it is introduced into a separation tank (not shown) or the like to separate the extraction medium and the extract quality. Further, in order to sufficiently contact the extraction medium fluid with the product to be processed, the extraction medium fluid is prevented from flowing out through the outside of the processed product case (c) without participating in the extraction. In (c), a packing (m) is provided between the inner bottom of the pressure vessel (b) and the spring (n) that presses the packing (m).
It is installed between (a).

加しない抽出媒流体が排出されることになる。(Problems to be solved by the invention) In the supercritical extraction device of the prior art, the space for accommodating the spring (n) for pressing the packing (m) has a pressure vessel (b).
This space is required inside and becomes a dead space that does not participate in the extraction action, which makes the pressure vessel large and the equipment cost high. In addition, it is necessary to open the open / close lid (a) and exchange the processed product case (c) and the processed product (d) after each extraction.
Since the lid (a) is fairly heavy and many springs (n) are actually arranged between the lid and the upper part of the processed product case (c),
It is difficult to maintain the attachment / detachment. Also a sintered filter
If (g) and (h) become clogged and the intake pressure becomes larger than the spring (n) force, the packing (m) will not be fully sealed and extraction from the outside of the processed product case (c) will occur. The extraction medium fluid that does not participate will be discharged.
