Factors to Consider for Managing Wort in a Brewery
Featured Product from Industrial Flow Solutions
When designing a brewery, waste management is often an afterthought. Selecting the proper equipment, from cooling systems to fermentation vessels, is no easy task. Inventory logistics, labor concerns, and market research all need attention. But a robust, updated waste management system is just as important as fermentation and plumbing equipment. Taking time to carefully consider a proper brewery waste management system upfront, is a crucial step in managing wort and producing beer – trust us, this will pay off in the long run.
There are three major factors to consider when designing brewery waste management systems: solids handling, chemical corrosion, and high temperature liquids.
- Brewing Solids
Solids used in the brewing process, such as spent grains, hops, flavoring agents, and yeast, can flood into the waste stream during the mashing and lautering process. These soft solids also get rinsed into drains during cleaning and sanitation but can form solid masses that can lead to issues. An improperly selected brewery wastewater pump can clog causing failures in your waste stream and result in costly repairs. Understanding the type and size of the solids will help you select the proper solids handling pump to avoid clogging.
- Chemical Compatibility
Clean-in-Place (CIP) uses cleaning chemicals combined with turbulent water to clean interior piping and spray balls to clean large surface areas. These chemicals can be extremely caustic or acidic. While they are tuned for specific cleaning processes and designed to work with brewing equipment, they can cause corrosion of waste management system components – leading to expensive repairs or replacements. Conducting a material compatibility analysis is an important step in avoiding corrosion when selecting a corrosion resistant pump for a brewery waste system. A chemical compatibility chart will help you identify the type of submersible wastewater pump you need for your cleaning processes.
- High Temperature Fluids
High-temperature fluids are inherent in the mashing, sparging and boiling brewing processes. CIP also uses extremely hot water, e.g., 180°F (83°C). The run-off from these processes will enter your waste stream, often retaining its high temperature. Many high temperature submersible pumps are not designed to operate in liquids at elevated temperatures and will prematurely fail putting your brewing operations in hot water.
