Steam recompression extraction device

The utility model relates to the field of bioengineering equipment, and discloses a steam recompression extraction device which comprises an extraction tank (8), a steam pipeline (9) connected to the top of the extraction tank (8), a steam inlet pipeline (15) connected to the bottom of the extraction tank (8) and a steam compressor (11), an inlet of the steam compressor (11) is communicated with an outlet of the steam pipeline (9), and an outlet of the steam pipeline (9) is communicated with an outlet of the extraction tank (8). And an outlet of the steam compressor (11) is communicated with an inlet of the steam inlet pipeline (15). By means of the technical scheme, in the working process of the extraction tank, steam generated in the extraction tank flows into the steam compressor through the steam pipeline, then the steam is compressed through the steam compressor, so that the temperature of the steam meets the requirement, and then the compressed steam flows to the bottom of the extraction tank through th
