The malaxing phase represents the fundamental moment for the extraction of the oil both in terms of quality and quantity. During this phase of preparation of the pulp that has just been crushed by the crusher, the combination of the mechanical action of the rotating reel and the correct heat exchange allows the micro droplets of oil to group into ever larger drops of oil, giving rise to coalescence. The engineering of the malaxers and their perfect development guarantees excellent organoleptic properties of the extracted oil and excellent results in terms of quantity extracted and energy saved. Precisely for this reason the F.lli Ferri malaxers have been designed with an innovative design that guarantees perfect mechanical action and immediate thermal conditioning.

Malaxers 1200 kg Green 12

The 1200 Kg / 1300 lt F.lli Ferri malaxers have been designed and engineered to guarantee the best performance in terms of quality of extracted oil and in terms of quantity. They are suitable for both batch and continuous processing. Object of study was the design of the main reel of the malaxer designed with an innovative design of the blade that helps during the mechanical action of the reel rotation, the cutting of the fat molecule and the formation of oil droplets. The number of reel revolutions also varies according to the diameter of the malaxer, calculated on the basis of the peripheral speed of the reel. Another object of study was the thermal conditioning system designed to ensure that there are no shaded areas in the malaxer, thus significantly reducing the malaxing times. The malaxer is totally closed in order to reduce the contact points of the pulp with oxygen and subsequently obtain an oil with low peroxides. Even the tube loading system allows to eliminate the points of contact with oxygen and the pump loading system guarantees a soft loading of the dough. The cover is equipped with a gas spring system for 180 ° opening; the washing of each malaxer is guaranteed by rotating heads which, connected to a high pressure pump, will allow a homogeneous washing of the whole tank; the bottom unloading with full bore represents another advantage for these malaxers as they speed up the final part of the unloading.
