Lesson 5 - Wort Separation Technology SAQ
This lesson allows you to test yourself on the material covered in Lesson 4 on ‘Wort Separation Technology’ and determine the level to which you have attained the outcomes.
Self-Assessment Questions
1. *For processing 10 t of malt by the mash tun, lauter tun and mash filter, provide comparative values for the following:
- grain bed loading
- strong worts flow
- cycle time (min /brews per day)
2. *Briefly explain the difference between a spent grain hopper and a spent grain storage silo.
3. *Explain how the mash filter plates are held in position during operation.
4. *Briefly describe two different false floor plate designs for a lauter tun.
5. *Provide typical lauter tun rig rotation speeds during lautering and also during grain discharge.
6. **Explain the pressure limitations of the mash tun, lauter tun, and mash filter. For all three devices, demonstrate how their design and operation prevent these limits being exceeded.
7. **With reference to wort separation steps and typical cycle times, explain why the mash filter time to process 10 t of malt is around 24% less than that required by the lauter tun.
8. **The diagram below is an annotated trend graph of a lauter tun wort collection. Explain what was happening, and how the lauter tun was responding to process conditions.
