The experimental tests were conducted using five different
mass flow rate values. To rapidly set the mass flow rate required
in a specific test condition, the authors have determined the correlation
existing between the cavity pump motor frequency and the
mass flow rate. For this purpose, an electronic welting system was
used. In the experimental tests, seven mass flow rates were used,
which produced seven set frequencies. For each seven frequencies,
the exact mass flow rate was calculated by measuring the time
required to welt 500 kg of olive paste. The measurement was replicated
4 times.
The mass flow rate of the olive oil and wastewater/pâté were
determined using the same welting system; otherwise, the husk
mass flow rate was determined indirectly based on the abovementioned
parameters. The process water added was measured using a
digital flow meter.
