Wort Boiling
Briggs will supply both Internal and External Wort Boiling systems and has commissioned a large number of both types.
However, Briggs has been promoting external Wort Boiling technology for over 20 years, and has installed more than one hundred large scale commercial systems... We call our external Wort Boiling systems "Symphony" - it’s an effective and demonstrably proven technology.
An external thermosyphon wort boiler has identical boiling characteristics to an internal wort boiler... it shares the same thermosyphon principle. Single phase (liquid) flows into the bottom of the tubes and two-phase flows (liquid plus vapour) out of the top.
The Briggs external wort boiling system has no practical limit to the heating surface area (because it’s not limited by the size of the vessel). Therefore, the following additional benefits can be achieved:
• Low ∆T - which means less damage to foam positive proteins and therefore better foam stability, low fouling rates and low colour pick-up
• Control of Evaporation - mass flow steam control and wort temperatures up to 103°C/217°F provide excellent DMSP to DMS conversion. The opportunity exists to reduce evaporation rates by increasing the amount of two-phase flow, which has been proven in large scale trials. Also proven is the massive reduction in energy costs
• Volatile Stripping - is far more effective as wort is returned above the liquid surface, no re-condensing of volatiles takes place in the body of the wort
• Wort Homogeneity - using our wort kettle configuration combined with mass flow steam control, excellent homogeneity is achieved ensuring that each particle of wort receives uniform heat treatment
• Rapid Heat-up Rate - no need to cover heating surfaces prior to steam-on which means the heat-up time is reduced
• Higher Wort Velocities - lead to lower contact times, reduced burn-on, less colour pick-up and extended times between CIP
• Lower CIP Volumes - no need to cover the entire heating surface for cleaning, as this is achieved by re-circulation
