For both craft breweries and large commercial brewing operations, hops play a crucial role in defining the aroma, flavor, and overall character of beer. While traditional methods of adding hops during brewing have been widely successful, new technological advances continue to transform the process, improving both efficiency and the quality of the final product. One such breakthrough is the Hop Extraction System—a highly efficient device that utilizes the principles of cross-flow filtration and centrifugation to ensure maximum extraction of hop flavors and aromas.
This system not only enhances the utilization of hops, thereby reducing waste, but also results in a fuller, richer beer flavor. With automated operating controls and seamless integration with fermenters, the hop extraction system provides brewers with a simplified, precise method for incorporating hops into their brewing process.
For brewers looking to integrate the Hop Extraction System into their production line, here are step-by-step instructions for using the Hop Extraction Tank:
Preparation and Cleaning
Before beginning the extraction process, thoroughly clean and sanitize both the extraction tank and the piping to ensure a contamination-free brewing process.
Connecting the Fermenter
Connect the fermenter to the hop extraction system. The keg interface of the fermenter should be connected to the front feed port of the electric diaphragm pump, while the bottom discharge port of the extraction tank connects to the fermenter’s beer outlet. This setup ensures that beer moves seamlessly between the two systems.
Water Addition and CO2 Purging
Add water to the water tank, and turn on the circulating water pump to automatically control water flow. At the same time, introduce CO2 gas to displace any oxygen in the extraction tank, ensuring that air does not interfere with the extraction process.
Hop Addition
Open the manhole and introduce the hops into the tank, while maintaining a CO2 environment to prevent air exposure.
Pressure Balancing
After adding the hops, balance the pressure between the fermenter and the extraction tank by adjusting the CO2 flow to ensure smooth operation.
Circulation Process
Open the valve to send the beer from the fermenter to the extraction tank. Start the circulation process and allow the beer to flow back and forth between the tanks for 4-6 hours. This ensures that the hops are evenly distributed and their flavors are fully extracted.
Final Transfer
Once the extraction process is complete, use CO2 pressure to transfer the beer back into the fermenter.
Cleaning the System
After draining the hops, clean both the extraction tank and piping to maintain a hygienic brewing environment and prepare for the next use.
The hop extraction system is essential for breweries aiming to improve production quality. It represents a significant leap forward in brewing technology, allowing for the efficient and controlled extraction of intense hop flavors and aromas.
