Hello WashU + any and all readers, my name is Rudy Lawler. I am an incoming Junior in Mechanical Engineering - I was at summer school during the start of the program which is why this post is just about my first week. After getting in Sunday dead tired, we quickly got into the swing of our projects. I spent the first two days taking tours of the brewery, having conversations/quizzes with some of the leads, and reading a manual on all of the equipment used in the Brewery's packaging lines. After that, my lead Terrence and I ran a "loss and waste analysis" on the packaging hall and found a good source of water loss for me to investigate: a tunnel pasteurizer that is currently using 10 times the water projected by the manufacturer. For the last 3 days of this workweek I read up on Pasteurizer technology, found the pathways by which water is lost/consumed by the pasteurizer, and gone over some theories that Terrence has for why the machine discharges more water than it shoul...
On Monday we arrived at the Rosslyn plant and were introduced to our mentors. My mentor for the CIPs is Monique, as she specializes in brewing. She briefly explained the brewing process that takes place at the plant. Interestingly, AB InBev uses locally grown hops from South Africa as oppose to importing from elsewhere. This practice is considered rare because hops are usually made in countries that are farther away from the equator and therefore have colder and longer winters. They also use locally grown barley that is used for all their beers except Bud. Another fun fact that I did not know before was the difference between a lager and an ale. During the fermentation process, if the yeast floats to the top it is an ale and if the yeast sinks to the bottom it is considered a lager. Finally, we got a tour through the packaging and bottling process of the final products. For my project, I’ve been assigned to improve the CIP system in the racking lines. The racking line is the s...
This was our last week at the Rosslyn Plant so I spent most of the week working on wrapping up my different projects and preparing to present on my work next week. I got to train operators at the plant to work on with a calculator I made, which was really cool because now I know that one of the projects I worked on will definitely make a lasting difference at the plant. This Saturday we took a suggestion from Rob at the Bentley Lodge and hired a driver to take us up to Bela Bela. We went zip-lining across a gorge, toured a croc farm where we got to eat croc burgers, and then went around a monkey sanctuary. It was all really fun to do, and a great last day in the area. Nozomi and Rudy had never been zip-lining before so it was a fun new experience for them, and I enjoyed it too, though it wasn't my first time. The croc farm had a lot of both baby and giant adult crocs, including a 700 kg, 42 year old one that was massive. We learned that because of the low temperature the crocs don...
