What is the best way to dry brewer's spent grains?

Continuous belt dryers like FlowDrya are ideal for drying brewer's spent grains at industrial scale. They provide gentle, low-temperature drying that preserves nutritional value while efficiently reducing moisture from 75-80% down to 10-12% for stable storage and transport.

What can dried brewer's grains be used for?

Dried brewer's grains have multiple valuable applications: high-protein animal feed for cattle, pigs, and poultry; food ingredients for bread, biscuits, and protein bars; fertiliser and soil amendment; and even as a biomass fuel source. Drying extends shelf life from days to months.

How much moisture do brewer's spent grains contain?

Fresh brewer's spent grains typically contain 75-80% moisture, making them heavy to transport and prone to rapid spoilage. FlowDrya systems can reduce this to 10-12% moisture for stable storage, or to custom levels based on end-use requirements.

Is drying brewer's grains energy efficient?

Yes, FlowDrya systems are designed for energy efficiency. They can utilise waste heat from brewery processes, CHP engines, or biomass boilers. Heat recovery systems further reduce operating costs, making spent grain drying economically viable for breweries of all sizes.

Overview

What are Brewer's Grains?

Brewer's spent grains (BSG) are the solid residue remaining after the mashing process in beer production. This by-product is rich in protein, fibre, and essential nutrients, making it valuable for animal feed and increasingly for human food applications.

Fresh spent grains contain approximately 75-80% moisture and begin to spoil within 24-48 hours without preservation. This short shelf life limits distribution options and forces many breweries to give away or dispose of this valuable material.

FlowDrya gently reduces moisture to create a stable, shelf-stable product that can be stored, transported, and sold at premium prices as dried distiller's grains or food-grade ingredients.

Benefits of Drying Brewer's Grains

Why Drying Brewer's Grains Creates Value

FlowDrya spent grain drying systems transform a perishable by-product into a valuable, tradeable commodity with extended market reach.

Extended Shelf Life

Dried grains can be stored for months without refrigeration, enabling stockpiling and year-round sales.

Increased Market Value

Dried brewer's grains command significantly higher prices per tonne than wet grains given to local farmers.

Expanded Distribution

Reduced weight and extended shelf life enable cost-effective transport to distant markets and export.

Nutrient Concentration

Drying concentrates protein and nutrients, increasing feed value per kilogram.

Food-Grade Potential

Properly dried grains meet food-grade specifications for use in bread, pasta, and baked goods.

Sustainability Credentials

Upcycling brewery by-products supports circular economy goals and enhances brand sustainability messaging.

Dry Brewer's Grains Applications

What Are the Applications of Dried Brewer's Grains?

Cattle Feed

High-protein supplement for dairy and beef cattle, improving milk production and weight gain.

Human Food Ingredients

Flour additive for bread, pasta, crackers, and energy bars, adding protein and fibre.

Aquaculture Feed

Protein source for fish and shrimp feed formulations in sustainable aquaculture.

Pet Food

Ingredient in premium pet foods providing protein and dietary fibre.

FlowDrya FAQs

Brewer's Grains Drying FAQs

For stable storage and animal feed applications, 10-12% moisture is typical. For food-grade applications, lower moisture levels around 8% may be required to meet specifications.

Wet spent grains should ideally be dried within 24 hours of production to prevent spoilage. FlowDrya systems can be sized to match brewery output for continuous processing.

FlowDrya's low-temperature drying preserves protein quality and nutritional value. Unlike high-heat dryers, there is minimal protein denaturation or nutrient degradation.
