I have recently taken on a role at a brewery in South East Asia. The brewery is now 13 years old and for several years has had issues with oxidized and souring beer. Who would want to take on this challenge, I hear you say? Well they made me an offer I couldn't refuse. When I arrived I immediately noticed issues with sanitation and inefficient processes throughout. Poor and worn-out equipment. The owners of the brewery are very wealthy but have neglected the running of the site for several years and for some reason the staff have been reluctant to ask for items to be replaced where necessary.
I've spent several weeks now improving recipes, replacing items and have ordered DO meter, QC analysis laboratory equipment, new pumps, hoses etc. Yesterday, one of the tanks started leaking from the lower exterior jacket beside the outlet valve which I immediately expected was a hole in the glycol jacket but the liquid coming out appears to be dirty water which is confusing.
On inspecting the interior of the tank, I was horrified to see the pitting and corrosion evident on the outlet valve and tank walls (this is after CIP). I've already suggested replacing three of the tanks but now I think I'm going to recommend ripping out ALL the tanks and starting again. Thoughts?
