Lesson 3 - Wort Separation Principles SAQ
This lesson provides the opportunity for you to test yourself on the material covered in Lesson 2 on Wort Separation Principles. It allows you to determine to the level to which you have attained the learning outcomes.
Self-Assessment Questions
1. *Name the three process objectives of wort separation.
2. *List four uses for a brewer’s spent grain.
3. *For the same grist charge, what is the relative flow rate of the lauter tun, mash tun and mash filter.
4. *Provide the Darcy’s Law equation for filter flow rate, along with descriptions of its variables.
5. **Sketch a typical wort collection profile showing gravity and volume. Identify the different process stages. Demonstrate how kettle gravity could be increased by 10% without loss of extract recovery.
6. **With the aid of diagrams, demonstrate the differences in grain bed formation and grain bed depth, between the lauter tun and the mash filter. Explain the relevance of this to strong worts flow rate.
7. **Explain the impact of wort viscosity on wort separation flow. Account for the difference in strong worts viscosity between the mash tun and the lauter tun.
8. **Explain why different milling systems are used for the mash tun, lauter tun and mash filter. Demonstrate how this impacts on the relative wort flow rate of these wort separation devices.
