Spent Grain Dewatering Centrifuge
Cost-Effective & Efficient
The most effective spent grain dewatering centrifuge on the market for off-the-grain distilling and wastewater removal
Effective
Reduces up to 90% of moisture at up to 100 GPM
Efficient
Cleans up/reduces waste stream, improves dryer efficiency, preserves grain
Convenient
Motor above the centrifuge, fully-englosed design, infinite turn-down ratio
Simple
Easy setup, one-man and toolless operation and breakdown
Efficiently dewatering spent grain has long been a problem for distillers (especially those in Kentucky who produce roughly 95% of the world’s bourbon). Through years of trial and error, however, centrifugal sifters have emerged as the best modern solution, with a specific configuration—dubbed the dewatering centrifuge—leading the pack. Whether dewatering spent grain for distillation, drying, disposing, or giving to farmers, we’re proud to offer the best combination of painless, efficient, and cost-effective on the market.

SIMPLE OPERATION
• Completely enclosed and easy to operate
• First setup within hours
• Toolless breakdown and cleaning
• Clean up waste streams
Operation
• Liquid is either gravity fed or pumped into the inlet at the lower end of the machine. From there it passes into a cylindrical mesh basket where a rotating paddle assembly separates liquids from solids by way of centrifugal force.
• The retained solids agglomerate inside the mesh basket and are moved to the oversize outlet by a helical scroll on the paddle blade assembly.
• Throughput and the degree of dryness of the solids can be controlled with the optional variable speed gearbox and the tilt angle adjustment of the separator body.
The dewatering centrifuge is a unique, proven technology utilized in many industries across the world.
Reasons distillers need to dewater their spent grain
The #1 reason brewers and distillers dewater their spent grain is because they’re required to by their city. This is because large volumes of organic solids can 1, disrupt the biological methods used to treat wastewater and 2, become an oxygen-sink that kills marine life.
But even if you’re not required to dewater, it’s an overall beneficial process whether you upcycle or throw it away. If spent grain is treated as waste, dewatering reduces most of the weight, and thus disposal cost. If it’s upcycled, dewatering vastly improves dryer efficiency. If you’re dewatering for distillation, using a dewatering centrifuge will yield the most fluid without crushing bitters into the wort. (Dewatering centrifuges are sometimes called de-sludgers because they can be used for corn with varying levels of efficiency depending on how homogenous the slurry is.)
Why this solution is the best on the market
Dewatering Centrifuge
• Removes up to 90% of moisture for remaining moisture content as low as 65%
• Easy cleaning with a tool-less single unit disassembly
• Controlled noise (85 decibels)
• Optimal design that prevents water from leaking into the motor
Next-Best Solution
• Removes up to 60% of moisture for remaining moisture content as low as 65% (according to manufacturer)
• Cumbersome cleaning with a time-consuming disassembly
• Very loud operation
• Design that results in water leaking into the motor
Both units are comparable in price.
