Filter Press consisting of a series of cloth filters fixed to frames, used for the large-scale filtration of liquid under pressure. |

A mash filter press is a large frame filter used for filtering mash. The mash goes through the same basic steps as a traditional lauter tun. The mash is pumped into the filter. The mash slowly fills up each chamber. Once the chambers are filled to capacity, a squeezing process begins to help remove wort and extract from the mash. Pressure from the mash and squeezing process will push the wort through a micron rated filter cloth before the wort gets pumped to the next phase.
In a traditional brewery, a lauter tun is used to remove the wort from the mash & grains. A lauter tun removes the extract via gravity and circulation. In the lauter tun there is a false bottom with a screen. The mash falls to the bottom of the tank and is circulated by a rake. Mash build up on the bottom creates a filtration medium. This allows the solids and liquid (clear wort) to separate.
Time Savings
Durable Materials of Construction—Stainless Steel and Polypropylene
Savings of Raw materials
Technical Advantages
Shorter Filtration Cycles
Lower Residual Moisture in Cake
Lower pressure to be used on plates
Higher Volume per Chamber
Shorter Filter Press Frames
Filling: Mash enters the chambers through a feed pump in the upper right corner. Mash will fill each chamber sequentially. |
Filtration: Once the chambers are full, the mash that is being pushed by the feed pump will force the liquid out from the chambers. |
Compression: Once the Feed Pressure has cycled out, the system will be closed and the membrane squeeze will begin. |
Draining: As the Squeezing is happening, the liquid will be forced out of the chambers and into one of the 3 return pipes. |
Grain Discharge: The hydraulic closure of press is opened. Each chamber is opened up for cleaning and grain discharge. |
