Yes, it is that fermenter in your attached link. Thanks for the confirmation.https://www.kegland.com.au/products/32l-304-stainless-steel-conical-fermenter
Just to confirm we are talking about the one in the link above. I am sure a lot of customers use sanitiser just to clean these dump valves out. With that said this type of ball valve has small cavities around the ball and I would recommend boiling between uses as it only takes a few moments to remove the ball valve and it may save you an infection.
