Topic starter has not reacted anymore since 2018, would be interesting to know if the problem was indeed the insufficient vent (inbreathing) capacity.

US Rao, are you still a member?

Here's a youtube film showing what most likely happened.

thanks Latexman, yeah I saw that too. "Funny" thing is that I encounter a similar problem, also with a curd tank.
Problem could be wrong basic tank design (wall thickness versus vent). The supplier does not make a good impression regarding design aspects, tells me "all our curd tanks are like that, so must be ok".....

Then, those two incidents provide a good economic basis to specify future curd tanks be designed, built, inspected, and stamped (certified) to an internationally recognized pressure vessel Code, and rated for "full vacuum". That's definitely a corrective action I would recommend.

From the video, it happens extremely fast. I would not size a relief device for that. I would specify the vessel be rated for full vacuum.

Good Luck,
Latexman
