Stainless steel wedge wire lauter tun screen

In modern brewing systems, efficient separation between wort and grain is essential for maintaining consistent beer quality and improving production efficiency. A stainless steel wedge wire lauter tun screen serves as a critical filtration component installed at the bottom of a lauter tun, helping separate liquid wort from solid grain particles during the lautering process.

Compared with traditional perforated plates or mesh screens, wedge wire lauter tun screens provide a continuous slot design, high open area, excellent mechanical strength, and improved resistance to clogging. These advantages make them widely used in breweries requiring stable filtration performance and long service life.

UBO Wedge Wire manufactures customized stainless steel lauter tun screens according to different brewery equipment designs, slot size requirements, and processing conditions.

What Is a Wedge Wire Lauter Tun Screen?

A wedge wire lauter tun screen is a specially designed stainless steel screening component used as a false bottom in brewing vessels. It consists of precisely welded wedge-shaped profile wires and supporting rods.

During the lautering process, the screen allows liquid wort to pass through while retaining grain particles on the surface. The filtered wort can then be collected efficiently while maintaining a stable grain bed.

The main components include:

• V-shaped wedge wires – form continuous filtration slots

• Support rods – provide structural strength and load-bearing capability

• Screen panels or curved sections – match different lauter tun designs

The V-shaped slot structure creates a wider opening toward the inside of the screen, helping reduce particle blockage and improving cleaning performance.

How Does a Stainless Steel Lauter Tun Screen Work?

During brewing, crushed malt is mixed with hot water inside the lauter tun to create a mash. After conversion, the lautering process separates the liquid wort from the remaining grain material.

The working process includes:

1. Grain Bed Formation

The crushed grain settles above the lauter tun screen and forms a natural filtration layer.

2. Wort Flow Through Screen Slots

The liquid wort flows downward through the precisely designed wedge wire openings, while grain particles remain above the screen surface.

3. Efficient Liquid Collection

The filtered wort is collected below the screen and transferred to the next brewing stage.

The slot opening design is critical because it determines the balance between:

• Wort flow rate

• Grain retention

• Filtration efficiency

• Cleaning requirements

Why Use Wedge Wire Screens for Lauter Tun False Bottoms?

1. High Open Area for Better Wort Flow

The continuous wedge wire structure provides a larger open area compared with traditional drilled plates.

Benefits include:

• Improved liquid flow

• Reduced resistance

• More efficient lautering performance

A higher open area helps breweries maintain stable production efficiency without increasing filtration pressure.

2. Excellent Anti-Clogging Performance

One common challenge in brewing filtration is screen blockage caused by fine grain particles.

The V-shaped slot design helps prevent particles from becoming trapped inside the openings because the slot becomes wider internally.

This provides:

• Easier cleaning

• Reduced maintenance frequency

• More stable operation

3. Strong Mechanical Structure

During operation, the lauter tun screen must support the weight of the grain bed and withstand repeated cleaning cycles.

Stainless steel wedge wire construction provides:

• High mechanical strength

• Good deformation resistance

• Long service life

This makes it suitable for both small craft breweries and large-scale industrial brewing systems.

4. Hygienic Stainless Steel Material

Stainless steel is widely used in brewing equipment because it provides:

• Corrosion resistance

• Easy cleaning

• Smooth surface finish

• Compatibility with food processing requirements

Common material options include stainless steel grades suitable for different brewery environments.

Slot Size Selection for Lauter Tun Screens

Selecting the correct slot size is one of the most important factors affecting lauter tun performance.

A suitable slot opening should consider:

• Malt particle size

• Grain bed structure

• Required filtration speed

• Wort clarity requirements

A slot that is too small may restrict flow and increase cleaning requirements.

A slot that is too large may allow unwanted grain particles to pass through.

Therefore, the ideal slot size should achieve a balance between:

• Effective grain retention

• High wort recovery

• Stable filtration performance

UBO Wedge Wire can customize slot openings according to specific brewing applications and equipment requirements.
