Process technology
PfaDuKo
The banke kettle vapor condenser
Wort boiling is by far the most energy-intensive process in the entire brewhouse and thus offers considerable potential for savings.
Valuable energy can be recovered in a kettle vapor condenser, which then can be utilized again in the brewing process. The PfaDuKo is therefore a critical component in reducing a brewery’s CO2 footprint.
Odor emissions from the brewery, which may be considered undesirable by some, are also significantly reduced.
Key facts
- primary energy savings of up to 60 %
- correspondingly lower CO2 emissions
- reduction of odor emissions
- due to its small footprint, easily retrofitted in a brewhouse
- a durable shell-and-tube heat exchanger
- increased efficiency through an integrated vapor cooler
- a crucial component for integrative energy management and optimization of the thermal energy balance
- capable of installation for heating the lauter wort
Function
The vapors rising from the boiling wort are directed from the wort kettle into the kettle vapor condenser. The vapor condenses on the vertical piping as a condensate film, which exits the vapor condenser at the cold water level. An additional condensate cooler is therefore not necessary.
The recovered energy can be reused to produce high-quality, high-temperature brewing liquor.
Primary energy savings
With this technology, primary energy usage for generating hot water can be reduced to a bare minimum. Lower operating costs as well as lower CO2 emissions are the result.
Minimal odor emissions
The vapor is full of undesirable aromas, which are present in the condensate and thus do not escape into the environment. In many cases, this means the brewery has already met legal emissions requirements with the vapor removed from its brewhouse emissions.
Customized energy management
Depending upon a brewery’s individual circumstances, the thermal energy thus recovered can be stored in a high-temperature thermal energy storage unit. This energy can be utilized later, for example, to heat the lauter wort.
Taking your individual circumstances into consideration, we can develop a concept tailored to your energy management needs.
Regenerative energy sources can also be effectively incorporated into this system.
