Barley Malt Residue Dewatering – A Byproduct of Malt-Based Beverage Manufacturing

Barley malt residue, commonly referred to as barley husk or spent barley, is a fibrous byproduct generated during the production of malt-based beverages. In large-scale malt extraction facilities, barley grains are processed to obtain soluble nutrients, sugars, and flavors for use in nutritional drinks and brewing. What remains after this extraction is a high-moisture, fibrous biomass that presents a significant challenge in terms of handling and disposal.

Nature of the Barley Malt Residue

The process of converting barley into malt involves steeping, germination, drying, and finally mashing. During mashing, the soluble components are extracted, leaving behind the barley husk—a dense, water-laden material that typically contains 85–88% moisture. While this residue is no longer useful for malt extraction, it is rich in fiber and residual proteins, making it suitable for animal feed, composting, or even biofuel applications.

However, the high moisture content makes the husk bulky, difficult to transport, prone to spoilage, and expensive to dispose of or repurpose unless it is dewatered effectively.

DeWatering Screw Press

Dewatering with a Screw Press

The Dewatering Screw Press provides a reliable and efficient solution for processing barley malt residue. Designed specifically to handle fibrous and organic biomass, the screw press applies continuous mechanical pressure to extract both free and loosely bound moisture from the husk.

In our experience, the screw press is capable of reducing the moisture content from 85–88% down to 60–65%, depending on the specific condition and character of the feed. This reduction not only makes the material lighter and easier to manage but also stabilizes it for further value-added use.

Applications of Dewatered Barley Malt Residue

Once dewatered, the barley husk can be repurposed in several sustainable and commercially viable ways:

Animal Feed – Provides roughage and fiber in livestock diets.
Composting – Enhances carbon content and structure in compost piles.
Fuel Substitution – Can be dried further and used as a solid biofuel in industrial boilers or biomass furnaces.
