How long does a batch take?
The holding time is fixed (30 minutes at 63 °C), but the full cycle also includes heating the milk up and cooling it down. Heating time depends on the batch size and the heat source (electric or gas), so larger batches take longer. Ask us for the cycle time of the size you are considering.
