PENGUKURAN KUANTITAS UAP MASUK REBUSAN SECARA TIDAK LANGSUNG MENGGUNAKAN GRAFIK ROTOTHERM

Abstract

Sterilization process is one of the keys to success in a Palm Oil Mill. In conventional palm oil mills that use
horizontal serilization, the fruit is heated in a closed vessel using pressurized steam at a pressure of 40 psi
and a temperature of 140oC. The performance parameters that determine the success of the process in
intermediate sterilization are pressure, temperature and time as well as steam requirements. This study aims
to determine the correlation between the area under sterilization graph represent the measurement of time
and pressure from every cycle of sterilization to oil losses in the condensate and empty bunch. The results
show that the higher the sterilization graph area which represents pressure and time, did not show significant
trend to the percentage of oil losses in the condensate and emptu bunch.
