The Design of Coffee: An Engineering Approach - Softcover

Inhaltsangabe

The Design of Coffee provides a non-mathematical introduction to chemical engineering, as illustrated by the roasting and brewing of coffee. Hands-on coffee experiments demonstrate key engineering principles, including material balances, chemical kinetics, mass transfer, fluid mechanics, conservation of energy, and colloidal phenomena. The experiments lead to an engineering design competition where contestants strive to make the best tasting coffee using the least amount of energy – a classic engineering optimization problem, but one that is both fun and tasty!

Anybody with access to a sink, electricity, and inexpensive coffee roasting and brewing equipment can do these experiments, either as part of a class or with your friends at home. The Design of Coffee will help you understand how to think like an engineer – and how to make excellent coffee!

This new fourth edition incorporates the latest research on coffee and features greatly revised labs on the energy of roasting and mass transfer in full immersion brewing. Improved labs feature water chemistry and brewing, pressure driven flow through grounds, espresso and viscosity, colloids and filtration, and coffee economics. This new edition also includes updated equipment recommendations and lists, an expanded glossary, and new bonus material about coffee.
