One Press. More Possibilities for Spent Grain.

What if the purpose of spent grain treatment is not only:

“How do we remove the water?”

But instead:

“How do we create more possibilities for this material?”

After brewing, brewer’s spent grain can become a valuable resource.

Some breweries send it directly to nearby farms.

Some use it for animal feed.

Others explore composting, anaerobic digestion or further processing solutions.

However, almost every brewery faces the same challenge:

Fresh spent grain contains too much moisture.

It is wet.

It is heavy.

It is difficult to store and transport.

And before it can become a useful resource, it often needs better handling.

Mechanical Dewatering Creates a Better Starting Point

A screw press does not try to completely dry spent grain.

Instead, it focuses on one important step:

Removing excess free water efficiently.

The process is simple:

Wet Spent Grain
↓
Feeding System
↓
Screw Conveying & Compression
↓
Liquid Separation
↓
Dewatered Spent Grain

During operation, the screw continuously moves the material forward while compression pressure separates liquid through the screen.

The solid fraction is discharged continuously and prepared for the next stage.

No complicated chemical treatment.

No waiting for natural drainage.

Just continuous mechanical separation.

More Than Dewatering — It Creates More Choices

Once spent grain becomes easier to handle, breweries have more flexibility in deciding what happens next.

Animal Feed

Spent grain is commonly used as a feed ingredient.

Dewatering can make collection, storage and transportation more practical for farms and feed-related applications.

Composting

For organic waste management projects, dewatered spent grain can be easier to mix, transport and process during composting.

Biogas Production

Spent grain can also be considered as an organic material source for anaerobic digestion systems.

Further Drying and Processing

When a lower final moisture level is required, mechanical dewatering can work as a pre-treatment step before thermal drying or additional processing.

The Real Value Is Not Only in Removing Water

Many breweries ask:

“Where can we send our spent grain?”

But another question may be more important:

“What do we want our spent grain to become?”

Feed?

Compost?

Biogas?

A processed ingredient?

The answer depends on the brewery’s location, production volume and final application.

A screw press does not decide the final destination.

It simply helps prepare the material for more possibilities.

From Brewing By-Product to Resource Opportunity

The process changes from:

Brewing → Wet Waste → Disposal

to:

Brewing → Spent Grain → Dewatering → Resource Recovery

One material.

Different applications.

More flexibility.

The right dewatering solution can become the connection between brewery waste management and resource utilization.
