At that time of year (October), the limitation of not being allowed to carry out night harvesting means being exposed to high ambient temperatures, so it is necessary to find solutions to help alleviate this effect. Tubular heat exchangers have long been used in the milling sector to cool the paste, but we consider that some of the damage to the aromas and minor components of the olives is already done when it has been “hot” ground. For this reason, at the beginning of the project we were looking for equipment that would allow us to cool the olive continuously before it passed through the mill. In this way we minimize the effect of the increase in temperature that the grinding itself entails, by doing it with a much colder olive. Subsequent malaxing and centrifugation processes are carried out without adding water or heating the paste.
