A support grid, also known as a lauter tun screen, is a filtration component used in brewing systems to separate liquid wort from spent grain during the mashing and lautering process. It is installed at the bottom of a lauter tun and functions as a mechanical filtration base that supports the grain bed while allowing liquid to pass through.
In brewing production, this component plays a direct role in determining filtration stability, extraction efficiency, and overall brewing consistency.
During lautering, hot water is sprayed over the mash to extract fermentable sugars. The support grid ensures that:
Liquid wort flows evenly through the grain bed
Solid grain particles remain supported and evenly distributed
Filtration resistance is controlled and stable
The screen typically uses a wedge wire structure, where V-shaped wires create precise slot openings. This design helps maintain consistent flow while reducing the risk of clogging.
Filtration efficiency in brewing is strongly influenced by the structure of the lauter tun screen. Key factors include:
A well-designed support grid prevents channeling, ensuring liquid passes evenly through the entire grain bed. This improves sugar extraction and reduces inconsistencies in wort quality.
The wedge wire structure provides a high open area while maintaining strength. This allows faster filtration rates without sacrificing structural integrity.
Unlike traditional flat screens, wedge wire slots reduce particle entrapment. This self-cleaning effect helps maintain continuous operation with less downtime.
Most industrial lauter tun screens are made from stainless steel due to its:
Corrosion resistance
High-temperature tolerance
Compliance with food-grade standards
Long service life under repeated cleaning cycles
These properties make it suitable for both industrial breweries and craft brewing systems.
Support grids are widely used in:
Industrial beer production lines
Craft breweries
Pilot brewing systems
Beverage research and development facilities
Different brewing styles may require customized slot sizes and panel configurations to achieve optimal filtration performance.
Manufacturers can customize support grids based on production requirements, including:
Slot opening size
Panel diameter and shape
Reinforcement structure
Flow capacity requirements
This flexibility allows breweries to match filtration performance with specific beer recipes and production scales.
A support grid (lauter tun screen) is a core component in brewing filtration systems that directly impacts efficiency and product quality. By ensuring uniform flow distribution, reducing clogging, and improving extraction performance, it helps breweries achieve stable and efficient production.
For brewing operations focused on consistency and performance, a properly engineered lauter tun screen is essential for long-term success.
