Packaging Planning, PDX Redux & Energy in the Brewery

My colleagues invited me to enjoy a few days off starting on Wednesday to visit my parents in Florida as well as Cigar City Brewing Company, and the SBC production team managed well without me…especially Mark who stayed Friday until 8:45 p.m. kegging beer after the engineer organized by PRO Engineering called on us late in the morning; I hope for us to keg off some more Goldencold this week. The week of July 9 is when we have various packaging experts coming in to commission the bottling line and train our small team. PDX engineers shared the nice graphic of how the wort boiler they engineered for our brewhouse works, attached. Dr. Furukawa contrasts its 3-D boiling to traditional 2-D…that is, in alternative boiling strategies, direct conduction occurs along the heating surface and then convective heat transfer occurs across a thermal gradient to the bulk of the wort. It works in breweries everywhere, but burn-on can occur, as can fouling. PDX uses direct food-grade steam injection into an annular conditioning chamber and by nature of its supersonic transition phase, the heating is ‘3-D’ and burn-on cannot occur. Energy recovery off the vapor phase of the kettle is still possible for the future. We’ve made several decisions that allow us to explore getting more from our energy. I enjoy sharing these with people who come for our daily tours (M-F 3:00 & 5:00 p.m., Saturday at 2:00 p.m.). We very much appreciate Fred offering tours last week!
