German term or phrase: Shaukelwasser

The text is about a pasteurizer. I don't understand what Schaukelwasser is.

Während die regenerative Sektion zur Aufwärmung gegen Schaukelwasser dient, erwärmt die Erhitzersektion die Milch auf 74 Grad Celsius beziehungsweise auf bis zu 92 Grad Celsius.

English translation:hot water circulation / circulating water

Explanation:
This comes from a comparison of the Zootechnika websites in German and English for a PAW 200 Pasteurizer.
(Knowledge of Hungarian would also appear to be useful, here)

By deduction, "Schaukelwasser" infers some kind of motion. The only motion in combination with water mentioned on the site is hot water circulation

The regenerative section mentioned is very probably a heat exchanger and the Erhitzersektion is the vessel in which the milk is heated to the specified temperature

forroviz (Hungarian for hot water) turns up at the same place as "..Wasser" in the German version

This is followed by keringtetéssel - kering means zirkulieren, kreisen

Ergo: hot water circulation

cooling of the heated milk by water in counter flow principle.

Counter flow may also be appropriate (in connection with gegen)

ASKER: Schaukeln was probably guesswork by the Hungarian translator in the sense of hin und her, backwards and forwards and recirculation

In many regenerative stages, the milk that has already undergone pasteurisation is used for pre-heating the cold milk entering the process.
In many cases, a product must first be heated for a certain treatment and then cooled. Pasteurization of milk is an example. Chilled milk is heated from perhaps 4 °C to a pasteurization temperature of 72 °C, held at that temperature for 15 seconds and then chilled to 4 °C again. The heat of the pasteurized milk is utilized to warm the cold milk. The incoming cold milk is pre-heated by the outgoing hot milk, which is simultaneously pre-cooled. This saves heating and refrigeration energy. The process takes place in a heat exchanger and is called regenerative heat exchange or, more commonly, heat recovery. As much as 94 – 95% of the heat content of the pasteurized milk can be recycled.

Is Wasser right?

It would make more sense if it wasn't water (or vodka).

https://www.zumexfoodengineering.com/en/product/flash-pasteu...
The regenerative stage consists in raising the temperature of the intake juice by exchanging it with the already pasteurised juice and this in turn reduces the temperature a few degrees above the intake juice.

https://assets.tetrapak.com/static/documents/processing/tetr...
Before being homogenized, the product is pre-heated in a Tetra Pak® Plate Heat Exchanger (PHE) by the outgoing pasteurized product... To ensure even heating on the product, final heating takes place in the PHE by means of an indirect hot water circuit.

There is a hot water circuit for what I presume is the product being described, but that isn't introduced until 2. Erhitzersektion... (gegen Heißwasser).

Find a Hungarian...

I think you should try and find a good Hungarian - English translator to get a definitive answer from the website link I posted. I think the Hungarian - German translator screwed up a little on a couple of things in your German text (regenerativ - Schaukelwasser and the use of gegen). As far as I can gather, this is about a heat exchanger and a heating vessel (regenerative Sektion and Erhitzersektion) and hot water circulation.

Or, failing that, post the question again with the Hungarian text under Hungarian to English :-)

fat separation from milk

Explanation:
The regenerative heating raises the temperature of milk to about 40°C to facilitate easy standardization. Heating then continues to 60°C to facilitate easy homogenization of the fat globules.

http://dairytechnologist.com/milk-pasteurization/

Fat in milk is present as discrete globules which, being insoluble and lighter than water, rise to the top in the form of a cream line. This characteristic is used in the commercial separation of cream from milk...
...Homogenisation is also essential for long-life milks (...) since separation of cream in the carton or bottle would make these products unappealing.

Notes to answerer

Asker: You are most likely right here. So warming takes place with the help of hot water circulation around the milk container. Later in the text there is also a cooling through ice water circulation. The "Aufwärmung gegen Schaukelwasser" was hard to make sense of.

16 hrs confidence:

swing regenerator counter-current fluid

Explanation:
The regenerator is a storage-type heat exchanger. The heat transfer surface or elements are usually referred to as amatrix in the regenerator. To have continuous operation, either the matrix must be moved periodically into and outof the fixed streams of gases, as in a rotary regenerator or the gas flows must be diverted through valves to and from the fixed matrices as in a fixed matrix regenerator. The latter is also sometimes referred to as a periodic-flow regenerator, a swing regenerator, or a reversible heat accumulator.
