### Lower Division Courses

**ECH 1: Design of Coffee – An Introduction to Chemical Engineering (4 Units)**-
*Prerequisites: None. Intended for non-majors.*

Many people are aware that chemical engineering exists as a profession – but few people have a firm idea about what chemical engineers actually do on a daily basis. This class is intended to serve as a non-mathematical introduction to how chemical engineers think, as illustrated by elucidation of the process of roasting and brewing coffee. The instructors will provide qualitative overviews of the basic principles of engineering analysis and design, and then guide the students in corresponding laboratory experiments testing the effect of design choices on the sensory qualities of coffee. In this manner, students will learn that even a process with only two “chemicals” – coffee beans and water – requires careful consideration of key physical concepts that are actually ubiquitous in chemical engineering. Why coffee? As we will discuss in this class, making coffee is actually a quintessential operation in chemical engineering. A raw material – in this case green coffee beans – undergoes a variety of chemical reactions in a roaster. The roasted beans are then ground to a specific size to optimize the extraction or “mass transfer” of caffeine and flavor molecules into the liquid phase, and a filtration step provides the final separation to ultimately deliver the cup of coffee. This class will start students down the path of thinking about coffee – and other processes or products – the way a chemical engineer does. Toward that end, the class will be organized around weekly laboratory experiments that each focus on a core chemical engineering concept. In weeks 1 and 2, the students will partially disassemble a drip coffee maker, and learn how the coffee maker can be considered as a series of “unit operations” that each accomplish a specific goal. In weeks 3 and 4, the students will learn how to roast green coffee beans using kitchen-scale roasters. The students will learn about the core reaction engineering concepts of “conversion” and “selectivity”, and importantly they will be able to taste the consequences of various roast profiles. Weeks 5 through 8 will then feature experiments exploring various design choices regarding grind size, temperature, pressure, filtration, with corresponding discussion about the underlying principles of mass transfer, fluid mechanics, thermodynamics, and colloid science. Week 9 will introduce basic engineering economics, comparing “break-even” curves for roasting your own coffee versus buying daily coffees from Starbucks. Finally, the class will culminate in week 10 with a design competition featuring a blind taste test of the students’ custom roasted brews. **ECH 5: Introduction to Analysis and Design in Chemical Engineering (4 Units)**-
