As shown in fig. 2, the decocting pot 1 is connected with a condensing reflux device 36 through a steam exhaust pipe 9, and a steam exhaust valve 35 is installed on the steam exhaust pipe 9.

When the decocting pot 1 discharges steam outwards, the steam discharging valve 35 is opened, the steam in the decocting pot 1 is conveyed into the condensing reflux device 36 through the steam discharging pipe 9, and the condensing reflux device 36 condenses the steam, thereby recovering the effective components contained in the steam.

The application example is as follows:

compared with the existing standard process, the extraction device for extracting the Chinese medicinal preparation has the advantages of simple and convenient operation, shortened extraction and concentration time, improved yield of the related extract and improved content of effective components in different degrees, and the comparison data are shown in the following table:

as can be seen from the table, the utility model can improve the extraction yield and the active ingredient content of the 25 Chinese patent medicines, reduce the loss of the medicines and improve the internal quality of the Chinese patent medicines.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications derived therefrom are intended to be within the scope of the utility model.
