Description & Rationale |
|
Application Purpose |
Wort Cooling (Knock-Out) |
To cool wort from boiling temperature (~98°C) down to yeast pitching temperature (18-22°C for ales, 7-12°C for lagers) in a single step. |
|
Flow Rates |
||
|
Wort Flow Rate |
~ 100 - 150 hL/h |
Example for a mid-sized craft brewery. Based on brewhouse size and desired whirlpool rest time. |
|
Cooling Media Flow Rate |
~ 120 - 180 hL/h |
Flow rate of coolant is typically 1.2 to 1.5 times the wort flow to achieve sufficient heat transfer. |
|
Temperatures |
||
|
Wort Inlet Temperature |
96 - 98 °C |
Temperature after the boil and whirlpool. |
|
Wort Outlet Temperature |
18 - 22 °C (or target pitch temp) |
The critical parameter to achieve. Requires a very cold coolant. |
|
Cooling Media Inlet |
-3 to -1 °C |
Must be a glycol-water mixture (e.g., 30-35% glycol) at a temperature well below the target wort outlet temp. |
|
Cooling Media Outlet |
~ 70 - 80 °C |
The glycol gets warmed significantly. This heat is wasted back to the glycol loop's cooling system. |
|
Heat Duty |
~ 400 - 600 kW |
The total amount of heat that must be removed from the wort per hour. Very high due to single-stage approach. |
|
Pressure Drop |
||
|
Wort Side |
< 0.8 - 1.0 bar |
Must be low enough to avoid crushing hot wort and causing cavitation in the wort pump. |
|
Coolant Side |
< 0.8 bar |
Must be within the capacity of the glycol circulation pumps. |
|
Design Pressure |
6 - 10 bar |
Standard for brewery PHEs to handle pressure spikes and allow for CIP. |
|
Plates |
||
|
Material |
AISI 316 / 316L Stainless Steel |
Food-grade, corrosion-resistant standard for breweries. |
|
Gaskets |
EPDM or NBR (Nitrile) |
Suitable for high wort temps and resistant to cleaning chemicals (CIP). |
|
Pattern/Chevron Angle |
High-Theta (e.g., 60°+/60°+) |
Creates high turbulence for efficient heat transfer, but also higher pressure drop. |
|
Connections |
4 x Tri-Clamp (1.5" or 2") |
Standard sanitary connections for breweries: Wort In/Out, Glycol In/Out. |
Shell and Tube Heat Exchangers: Durable and suitable for high-pressure applications. Often used in steam heating systems or where fouling is a concern. Require more space and are harder to clean than plate models.
Spiral Heat Exchangers: Excellent for viscous fluids or applications with particulates. Less common in standard brewing but useful in specialty processes like mash recirculation or yeast handling.
Double-Pipe (Concentric Tube): Simple design, often used in small or pilot systems. Lower efficiency but easy to fabricate and maintain.
Wort Cooling
One of the most critical applications of heat exchangers in brewing is rapidly cooling hot wort after the boil. Immediate cooling is essential to prevent bacterial contamination, reduce haze formation, and prepare the wort for yeast pitching at the ideal fermentation temperature.
Sanitizer Heating
Effective sanitation is crucial in brewing environments. Heat exchangers are used to heat cleaning solutions such as caustic soda (CIP – Clean-in-Place) or peracetic acid to their optimal operating temperatures, enhancing microbial kill rates and cleaning efficiency.
Steam Generation
Heat exchangers serve as key components in steam generation systems, where they transfer heat from a primary source (e.g., hot oil or exhaust gases) to water, producing steam for various brewery operations.
Energy Recovery
Modern breweries increasingly adopt energy recovery systems to reduce utility costs and environmental impact. Heat exchangers capture waste heat from processes like wort boiling, fermentation cooling, or refrigeration systems.
Preheating
Preheating raw materials such as brewing water, malt slurry, or yeast starters using recovered heat improves overall thermal efficiency and reduces cycle times.
Temperature Control
Precise temperature management is vital throughout the brewing process. Heat exchangers provide accurate heating or cooling for sensitive stages such as mashing, boiling, and fermentation.
Integration with Other Systems
Beyond core brewing functions, heat exchangers are integrated into auxiliary systems to improve facility-wide efficiency and sustainability.
