Every brewery produces more than beer.

After the brewing process, there is another material left behind:

Brewer’s Spent Grain (BSG).

It contains valuable organic matter, but there is one major challenge:

High moisture.

Fresh spent grain is heavy, wet and difficult to handle.

For breweries producing BSG every day, this can create problems:

• Higher transportation weight
• Limited storage time
• More difficult handling
• Increased drying requirements

The question is:

Why transport and process so much unnecessary water?

Mechanical Dewatering Changes the Process

A screw press provides a continuous way to remove free water from spent grain.

The process is simple:

Wet BSG → Screw Press → Water Separation → Dewatered Spent Grain

The screw moves the material forward while gradually increasing compression.

Water passes through the screen.

The solid material continues to the discharge outlet.

No complicated treatment.

Just continuous mechanical separation.

Why Dewater Spent Grain Before Further Processing?

For breweries using drying systems, mechanical dewatering can be an important pre-treatment step.

Instead of:

Wet BSG → Dryer

A more efficient process can be:

Wet BSG → Screw Press → Dryer

The screw press removes part of the water mechanically, allowing the dryer to focus on the remaining moisture.

This can help improve the overall processing efficiency.

What Can Dewatered Spent Grain Be Used For?

After dewatering, BSG can be prepared for different applications:

Animal Feed

A common use for brewery spent grain, especially for local livestock farms and feed businesses.

Biogas

BSG can serve as an organic material source for anaerobic digestion projects.

Composting

Dewatered organic material can be easier to handle in composting systems.

Further Drying & Processing

For applications requiring lower moisture, dewatering can work as the first step before drying.

More Than Waste Treatment

A screw press is not only removing water.

It helps breweries change the way they manage their by-product.

From:

Wet material → Limited handling options

To:

Better moisture control → More recovery possibilities

For breweries, the goal is not simply to dispose of spent grain.

It is to make this by-product easier to handle, transport and reuse.

Is a Spent Grain Screw Press Suitable for Your Brewery?

The right solution depends on:

✔ Daily BSG production
✔ Moisture content
✔ Feeding method
✔ Required capacity
✔ Final application
