| Technique | Description | |
|---|---|---|
| Techniques related to the use of centrifuges | ||

| (b) | Rinsing of the cream heater with skimmed milk or water | Rinsing of the cream heater with skimmed milk or water which is then recovered and reused, before the cleaning operations. |
| Techniques related to ice cream production | ||
| (c) | Continuous freezing of ice cream | Continuous freezing of ice cream using optimised start-up procedures and control loops that reduce the frequency of stoppages. |
| Techniques related to cheese production | ||
| (d) | Minimisation of the generation of acid whey | Whey from the manufacture of acid-type cheeses (e.g. cottage cheese, quark and mozzarella) is processed as quickly as possible to reduce the formation of lactic acid. |
| (e) | Recovery and use of whey | Whey is recovered (if necessary using techniques such as evaporation or membrane filtration) and used, e.g. to produce whey powder, demineralised whey powder, whey protein concentrates or lactose. Whey and whey concentrates can also be used as animal feed or as a carbon source in a biogas plant. |
