Whirlpool Trub (Hot + Cold Break Brewery Solids) Storage

Storing Whirlpool Trub? Start Here

If you're in the brewing or distilling business, you're familiar with trub, the mix of proteins, hop resins, and other solids that form during the boiling and cooling stages of wort. Managing this byproduct is crucial, especially when it comes to storage. Trub is slightly acidic and contains a mix of solids, making it a unique challenge. Whether you're a craft brewer or running a large-scale operation, understanding how to store trub safely and efficiently is key to maintaining smooth operations and meeting regulatory standards.

Can you store it in a poly tank?

For storing trub, especially when it's cooled or at cold-break stages, HDPE tanks are a viable option. However, they are not suitable for hot-break trub directly from the kettle, where temperatures can exceed 175°F. For these high-temperature conditions, stainless steel tanks are recommended to ensure safety and compliance.

Handling the Heat and Solids

The main challenge with trub storage is its temperature and solid content. Hot-break trub can reach temperatures up to 210°F, which exceeds the limits of HDPE tanks. Additionally, the solid content requires tanks with agitators and specialized discharge systems to handle the thick mixture effectively.

The safety that actually matters

• Use stainless steel tanks for hot-break trub to handle high temperatures.
• Ensure tanks have proper agitation and discharge systems for solids.
• Follow FDA and industry standards for food and animal feed safety.

Common questions

Can I use HDPE tanks for all trub stages?

HDPE tanks are suitable for cooled and cold-break trub but not for hot-break trub due to temperature limits.

What materials are best for gaskets?

EPDM and silicone rubber are standard for gaskets, providing good temperature and chemical resistance.

How much trub does a typical brewery produce?

A craft brewery might generate 2-5 gallons per session, while larger operations can produce up to 500 gallons.
