  • 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.

Design of equipment for media and inoculum preparation, fermentation and recovery, buffer preparation, purification, and utilities will be discussed. In this discussion, general equipment design issues will be included such as piping and pump sizing and pressure vessel design. Integral parts of the facility such as purified water and water-for-injection systems, clean steam generation, clean-in-place systems, biowaste treatment, and HVAC (heating, ventilation, and air conditioning) will be discussed in detail and sizing concerns addressed. Industry standards for process control, automation, and data acquisition will also be covered. The second focus of the course will be compliance with current GMP, the laws governing production of human and veterinary drugs, as enforced by the Food and Drug Administration. Concepts such as validation master planning, validation protocols, protocol execution, and change control will be discussed as applied to both equipment and process qualification. Standard operating procedures and batch records will also be discussed for new and established operations. Ideas for successful project management and facility startup will be introduced throughout the course material.

    Estimated ABET Category Content:
    Engineering Science: 1 unit
    Engineering Design: 3 units

    Design Statement: Given a general objective of the experiment, students will design experimental setups (e.g., determine how equipment components will be interconnected, determine where sensors should be located), protocols (e.g., how samples will be taken and analyzed) and procedures (e.g., what chemical compounds and/or experimental variables to investigate) to meet the objectives of the laboratory experiments.

  • ECH 169: The Design of Cocktails - Applied Thermodynamics and Transport Phenomena in Mixed Drinks (1 Unit)
  • Prerequisites: ECH 145B, ECH 152B, and consent of instructor.
    Engineering principles can be used to understand diverse phenomena. In this class we will show how core chemical engineering principles apply to cocktails. The students will be challenged to apply quantitatively their understanding of heat transport, mass transport, thermodynamics, and phase stability to the preparation of and sensory properties of mixed drinks. Hands-on quantitative experiments (e.g. of ice-water-ethanol phase diagram) will be combined with qualitative sensory analysis, culminating in the end of the quarter with a design contest.
