Energy. Reduce, Re-use, Recycle

There’s a lot of heating and cooling involved in making ice cream so we’re always looking for creative ways to reduce our energy use. One critical stage in the process is cooling each batch of ice cream mix fast after it has been blended and cooked in stage 1. This is done as it is pumped over to a chilled tank to be held overnight where the mix settles before stage 2 (freezing!) the next day.

A few years ago we adapted our process and installed a number of plate heat exchangers for us to recycle energy, and reduce our total consumption: we now cool the hot ice cream mix from the first batch using cold incoming ingredients from the following batch (which is helpfully warmed up pre-cooking). Every incremental improvement like this helps us reduce our carbon intensity as progress towards our goal of a 43% reduction by 2030.
