The present invention provides a process for treating a wort composition in a kettle, said method providing a significant energy saving compared to existing wort treatment processes. In particular, the process includes a hot-hold step for the wort, followed by gas sparging at elevated temperatures.

A device and method for recovering energy from a hot medium, in particular from hot wort or hot mash for a beer brewery, including a first heat exchanger device for a heat transfer medium that is arranged in particular downstream of a device for heating, boiling or keeping wort or mash warm and is designed such that the heat transfer medium can be heated while cooling preferably wort or mash, wherein at least one heat consumer of the brewery is heated with the heat transfer medium. The heat transfer medium cooled down during heating the heat consumer can be recirculated to the first heat exchanger device in the circuit.

A method for a multi-step supply of heat to at least one processing device in a brewhouse includes storing in an energy storage tank a heat transfer medium, which is heated by a heat recovery device before it is stored; in a first phase, supplying heat to the at least one processing device mainly by supplying the heat transfer medium from the energy storage tank to the at least one processing device; and, subsequently, in a second phase, supplying a heat amount, which increases over time, of heat of non-recuperative origin to the heat transfer medium supplied to the at least one processing device, and thus to the at least one processing device.

A system and method for generating wort utilizing steam injection heating and stratified flow. The system mixes a fine ground grain with water to form a slurry. The slurry is pumped through a steam injection heater to form a mash. The heated mash enters into a stratified vessel that creates a stratified temperature profile from a first end to a second end. The stratified heating vessel allows the mash to flow from the first end to the second end without internal mixing. After retention within the mash coil, the wort is directed to a mash filtration unit. After filtration, the wort enters into a boil kettle and is heated using a second steam injection heater. The boil kettle includes a spray head that directs brewing liquor onto the wort to reduce foam within the boil kettle. Finally, the wort passes through a scraped surface sieve that removes particles from the heated wort.

A method for treating a wort in a kettle provides a kettle with an inlet for feeding a wort into the kettle and with an outlet for flowing the wort out of the kettle. A heating means for bringing the wort contained in the kettle close to or at boiling temperature, as well as for controlling the temperature. A gas sparging system for sparging an inert gas into said wort. Feeding wort from a lautering step into said boiling kettle through the inlet, the wort at a temperature below its boiling temperature. During sparging, heating the wort and maintaining it at a treatment temperature below the boiling temperature of the wort for a duration between 15 and 90 min, and no longer than required to evaporate at most 4 wt. % of water initially in the wort. Transferring the treated wort to a trub separation step through the outlet.
