Approximately 75 L of soybean oil, purchased from a wholesale
supplier (Gordon Food Services, Chicago, IL), was added to the
steam-jacketed tank 1 (T1) and heated to ~93 C (Fig. 1).
Oil heated in T1 was pumped through the piping, via the centrifugal
pump until the exiting oil was visibly clear (~5 L), to flush
out any liquid or debris that may have been present in the piping
prior to the start of each trial. Rinse oil was disposed of by pumping
to a collection tank. Once clear, the remaining oil was re-circulated
through the piping back to T1.
