Lesson 10 - Jacketed Vessels
This lesson explores another type of common heat transfer equipment used in brewing, namely jacketed vessels. It investigates the application, specifications, and the operating conditions of these exchangers. It also looks at their design and sizing considerations.
Preface
In the previous lesson, we explored how heat is transferred when beer or wort is pumped through an inline exchanger. In this lesson, we will explore how heat is transferred when beer or wort is contained in a vessel. We will learn about the technologies used for this type of heat transfer, and the mechanisms that govern it. We will also consider its design and operation.
As you will recall, a heat exchanger is defined as a device that transfers heat from one fluid to another, across a barrier that prevents the fluids themselves coming into direct contact. One fluid will leave with more energy (warmer) than when it entered the exchanger, and the other will leave with less energy (colder).
The previous lesson described several applications of inline heat exchangers. Can you identify any examples in the brewing process where vessels are used as heat exchangers? Give yourself 5-10 min to think about this, and then click ‘Next’ to continue with this lesson.
