What is the strong worts flow for a Lauter Tun?
240 hL/h
What is the cycle time in minutes for a Mash Filter?
110 min
What is the cycle time in brews per day for a Lauter Tun?

What is the primary function of a spent grain hopper?
Buffer tank designed to receive the whole brew in 10-15 min
How is the plate pack of a mash filter held in position during operation?
Compressed together by a hydraulic ram applying 120 bar pressure
What are the two designs for false floor plates in a lauter tun?
- Solid plates with milled slots
- Wedge wire segments
What is the typical rotation speed during lautering in a lauter tun?
0.1 rpm
What is the maximum differential pressure (DP) limit across the false floor in a mash tun?
0.1 bar (1,000 mmwg)
True or False: The mash filter operates by draining wort from the grain bed.
False
What happens if the differential pressure exceeds its limit in a mash tun?
It pulls in air to reduce the vacuum
What is the purpose of the vacuum breaker in a mash tun?
Safeguard against floor collapse
What is the cycle time for strong worts collection in a Lauter Tun?
40 min

110 min
Fill in the blank: The mash filter uses _______ hL of water for a 10 t batch of malt.
550
What is the main advantage of the mash filter over the lauter tun in terms of processing time?
24% less time to process 10 t of malt
What is the role of rakes in a lauter tun?
To reduce DP and maintain flow rate
How does the mash filter handle inlet pressure limits?
Switches from flow control to pressure control
What is the effect of higher viscosity wort on flow rate in a mash filter?
Reduces wort flow rate per unit of surface area
What is the typical sparge volume used by a Lauter Tun?
400 hL
What is the pressure limit for the inlet of a mash filter?
0.5 bar
Fill in the blank: The lauter tun uses _______ hL of water for a 10 t batch of malt.
720
