Described material disc pore size is 1 ~ 5mm;

Utilize a circulation extracting method for device described above, comprise the following steps:

Step one: be placed in by material to be extracted on material disc in extraction chamber, evenly spread out, closes extraction chamber; In distillery, import Extraction solvent, close distillery;

Step 2: distillery starts to add thermal distillation, the steam of generation enters extraction chamber through conduit I;

Step 3: the material to be extracted on material disc is by steam soak extraction, and a part is extracted after steam reduces condensation with temperature and naturally dripped, and after the filter membrane bottom material disc filters, gained extract enters distillery by conduit III; The uncooled extraction steam of another part flows to distillery by conduit II after the filter membrane on the upside of material disc filters, and by condensing tube condensation;

Step 4: the solvent entering the extract of distillery is added thermal distillation, the steam of generation enters extraction chamber through conduit I, repeats step 3, to realize circulating the active ingredient extracted in material to be extracted;

Step 5: extract after terminating, gained extract is derived through drain pipe;

In the form of sheets, its thickness is not more than 1mm to material to be extracted in described step one.

Beneficial effect of the present invention:

Circulation extracting apparatus provided by the invention, by arranging many conduits between the extraction chamber closed and distillery, and check valve is set on conduit, realization vapor recycle soaks thing to be extracted, and the infiltration being more conducive to treating active ingredient in extract is extracted, and arranges material disc in extraction chamber, in the both sides up and down of material disc, filter membrane is set respectively, the steam or extract that contain active ingredient are directly filtered rear condensation and collects process, simplify technical process, saved mass energy;

Circulation extracting method provided by the invention, makes whole technical process uninterrupted continuously, simplifies equipment, saved mass energy, and simple to operate, convenient and practical.
