2015-2-18 · Practical applications: The practical application of this work includes understanding the effects of four different crushers on oil drops and pit fragmentation. The experimental data could be useful to define the best malaxation time and to gain a better understanding of the minor components distribution in olive oil.
The tests performed showed that hammer-crushing produces a more intense fragmentation of the olive pits than the disk-crusher, thus resulting in a more substantial increase in output temperature. Higher temperatures in the crusher during olive processing lead to a shorter preservation of the oils.
