Abstract

The invention relates to a wort boiler apparatus comprising a wort boiler vessel and at least one separate heating circuit external of the boiler vessel and including a heat exchanger for heating or boiling the wort, the heat exchanger comprising an arrangement of heat exchanger pipes for passing the wort through the heat exchanger. The object of the invention is to provide a heat exchanger adapted to be adjusted to different evaporation values as required for making different types of beer. To attain this object, the invention provides that the arrangement of heat exchanger pipes includes pipe connections and valves in an arrangement permitting the wort to be passed through the heat exchanger along flowpaths of different lengths.

Claims

1. A wort boiler apparatus comprising a wort boiler (1) and at least one separate heater circuit including a heat exchanger (2) for heating or/and boiling the wort, said heat exchanger (2) comprising a group of heat exchanger pipes for the passage of the wort through the heat exchanger, characterized in that said heat exchanger comprises at least one heat exchange section (3) composed of a plurality of heat exchanger pipes and having a wort inlet and a wort outlet, said heat exchange section (3) being provided with pipe connections and valves arranged to permit the wort to flow through said heat exchange section along flow paths of different length, each said flowpath including all of said heat exchanger pipes.

2. Apparatus according to claim 1, characterized in that said heat exchanger pipes are adapted to be interconnected in series and/or in parallel for the formation of flow paths of different lengths.

3. Apparatus according to claim 1 or 2, characterized in that each heat exchange section includes nine heat exchanger pipes.

4. Apparatus according to claim 3, characterized in that said heat exchanger pipes of said heat exchange section are adapted to be interconnected in series for the formation of a wort flow path of a first length, and in a series connection of groups of three pipes each for the formation of a wort flow path of a second length.

5. Apparatus according to claim 1 or 2, characterized in that all of said heat exchange sections (3) are enclosed in a common outer casing forming the outer wall of said heat exchanger for the passage therethrough of steam used as a heater medium.

6. Apparatus according to claim 1 or 2, characterized in that bypass pipings of reduced cross-sectional area are provided for the drainage of pipe branches shut down by the closure of respective valves.
