Help, what device is shown in the image below?

Just find the drawing and check it, and you’ll know

Take a photo of the entire tank, and take a photo of the nameplate as well. This isn’t a standard glass-lined reactor or carbon steel reactor; it looks like a stainless steel device used in pharmaceutical factories.

It’s best to disassemble devices without blueprints before using them; industrial production is different from other types. There are certification training programs for vehicle use in a general sense, and dealerships are available in case of problems. This also needs to follow such procedures within a certain circle of users. Oh, disassembly requires technical expertise. Let’s talk about these appearance guesses again. This one with a lifting ring can be lifted out using external force; after it is filled, the lifting ring needs to be removed, and a sealing cover must be tightened before it can be used. Is there a barrel with a screen inside this “plug”? Like installing some catalysts? Reagent? Or some other agent, draw it out after use, and then add it. It seems that this reactor is not of the type used for continuous production; it is likely a device designed for indirect production. The above are just guesses. :lol

It looks like this inside; it is a stainless steel fermentation tank

I’ve seen this before; many manufacturers use it as a device operating at atmospheric pressure. In reality, when steam is supplied to the jacket, it functions as a pressure vessel, and penalties are imposed if detected by regulatory authorities. Similar to a reaction kettle. This port at the top is usually a sampling port. It could be the thermometer socket, but the possibility that it’s not installed is low.

Do you know what the specific name of this item is? Something like a plug or a stopper, for example

The scientific names were chosen by the designers; you should ask them. Or you can tell me the specifics, and I’ll see if I can help you.
