Lesson Information
Pre-requisite Knowledge:
- Introduction to Wort Separation (Wort Separation/Lesson 1)
- Wort Separation Principles (Wort Separation/Lesson2)
Learning Outcomes:
- Outline the process objectives of wort separation.
- Explain the role of the grain filter bed.
- Understand how the grain filter beds are formed differently by the lauter tun, mash filter and mash tun.
- Produce a typical wort collection gravity profile with values for gravity and volume. Include the following within this: strong worts, sparge, sparged worts, weak worts and last runnings.
- Describe the removal and disposal of spent grain.
- Define Darcy’s Law for calculating the filtered wort flow rate of a wort separation device; explain each of the variables involved.
- Explain why wort viscosity can vary, and how it affects filtered wort flow.
- Provide typical grain bed loadings for the different wort separation devices, and then calculate their relative impact on filtered wort flow.
- Demonstrate how the different milling requirements for different separation devices affect grain bed permeability; evaluate the impact on filtered wort flow.
- Explain why a mash separation device has to operate with a low differential pressure limit; describe the consequence for filtered wort flow.
- Demonstrate, using Darcy’s Law, the relative flow rates for each mash separation device for a set grist charge.
