(20 cards)
What is the total cycle time for a mash filter to achieve 13 brews per day?
110 minutes
How long does it take to fill the mash filter?
5 minutes
What is the duration for filling and filtering strong wort?
23 minutes
How long does pre-compression of the mash filter take?
4 minutes
What is the time required for sparging and collecting sparged worts?
45 minutes
How long does the emptying process of the mash filter take?
5 minutes
What is the duration for spent grain discharge in the mash filter operation?
20 minutes
Fill in the blank: The total time for all operations of the mash filter is ______ minutes.
110
What pressure is the compressed air supplied to the membranes during pre-compression?
0.5 bar
Why is it important to maintain forward flow during sparging?
To prevent the spent grain bed from collapsing or cracking
What is the sparge flow rate relative to the strong worts flow?
Roughly 75%
True or False: The mash filter takes advantage of the reducing viscosity of sparged worts like the lauter tun or mash tun.
False
What happens if the grain bed is unevenly distributed during sparging?
There will be preferential flow through some plates and less flow through others
How long does the sparging process last in the mash filter?
45 minutes
What is the consequence of a collapsed or cracked spent grain bed during sparging?
The pumped sparge can take the path of least resistance
What is the initial action taken when the mash transfer is complete?
The mash inlet main is closed off
What is vented to the atmosphere during the filling of the mash filter?
Displaced air
How does the mash enter the filter plates during filtration?
Through the top inlets
Fill in the blank: The filtration process of strong worts takes ______ minutes.
23
What happens to the flow of strong wort after four minutes of pre-compression?
Flow has reduced by about 50%
