German to English Tech/Engineering Chemistry; Chem Sci/Eng precipitation and filtration

Hallo ProZ-Profis!

This term appears in the following context:

Rezept Y wird eingesetzt, wenn das Filtrat aus der Faktor IX-Adsorption (Behälter 111/Rührdrucknutsche 000) als Ausgangsmaterial übernommen wird.

This is from an SOP for the precipitation and filtration of various factors. Unfortunately the term only occurs once in the document and no further context is provided.

After an exhaustive internet search about the best I can come up with is "agitated nutsche filter". However, "nutsche" does not sound like English to me and Ernst calls a "Nutsche" a suction filter or strainer. I am a little suspicious of "agitated nutsche filter" because most of the websites where this term shows up feature a nearly identical and somewhat questionably written definition. In addition, a lot of these websites are foreign (i.e. Asian, German-language etc.) and contain spelling errors and other clues that they were not written by native English speakers. Could it be that the term "Rührdrucknutsche" was incorrectly translated as "agitated nutsche filter" at some point and has simply been picked up by other translators/websites? In today's cyberspace of rapidly self-multiplying errors it certainly wouldn't be the first time :)

Could someone with EXPERIENCE in this field kindly clue me in to what we call this in English? I am willing to accept "agitated nutsche filter" but I need confirmation from some native English-speaking experts first.

Vielen Dank im Voraus,

P.S. This is all the context I have. If anything about the style/substance of this query is displeasing to you, then kindly move on to the next one. Thank you so much in advance!
