Germination Flashcards
What is the purpose of germination specifically in malting?
Create enzymes
Partially digest structures (cell walls, protein chains, etc)
Minimize kernel consumption
What is the primary reason for germination in the wild?
Perpetuate plant species reproduction
How long is the germination cycle?
86-120 hours
What is the optimal temperature range for germination?
17-22c
Name 3 germination equipment requirements
Perforated floor
Turning machines
Water supply
Air flow regulator
Steeped malt in (gravity or mechanically fed)
Humidifier arm
What are some advantages to circular vessels?
Easier and quicker load in/level
Improved air flow
Easier to automate
Why do you need airflow?
Provide o2
Remove co2
Control grain temp
When is grain considered fully modified?
45% moisture content
Why is it important for grain to be turned regularly?
Adequate aerobic respiration for all kernels
Avoid clumping together
Why is water important during germination?
Facilitate movement of hormones and enzymes
Carbohydrate simplification
Why is it important to make sure grain is evenly loaded and level?
Keep consistent airflow through entire bed and ensure aerobic respiration
