Extra vrigin olive oil(also known as EVOO) is extracted from fresh olive fruits by cold-pressed process with minimal processing steps in order to retain as much of their natural minerals, vitamins and nutrients as possible.
工艺描述 PROCESS DESCRIPTION
|
A |
OLIVE FRUITS RECEPTION PROCESS |
|
|
The harvested olive fruit from the olive orchards are usually collected in 20kg or 400kg plastic bin;then the fruits are poured into the feeding hopper by labors or forklift (for 400kg box)and conveyed to the next station-washing machine;The belt conveyor is equipped with one or two air fans to remove the leaf and debris mixed in the olive fruits. |
|
B |
OLIVE FRUITS WASHING PROCESS |
|
|
The olive fruits are conveyed into the washing machine and then rinsed&washed to remove the dust under the function of strong water flow.Then the washed fruits flow through one vibration sieve mounted on the washing machine to separate the small leaves and the clean fruits comes down to the hopper of the screw conveyor for next step. The water is collected for recovery by the circulation tank under the vibration sieve. |
|
C |
OLIVE FRUITS CRUSHING PROCESS |
|
|
After cleaning,the washed olive fruits are conveyed into the crusher by screw conveyor.The crusher can work as a separate unit equipped with screw conevyor or screw pump to distribute the paste into mamalaxer or mounted on the malaxer together with the screw conveyor. |
|
D |
OLIVE PASTE MALAXING SYSTEM |
|
|
After crushing, the olive paste is pumped into the horizontal mixing tanks (known as malaxer or kneading machine). Each malaxer consists of a stainless steel tank with a central screw stirring the paste slowly and continuously at a monitored temperature. The equipped jacket of malaxer allows to heating the inside olive paste evenly by the hot water circulated inside the jacket.small oil drops released during the malaxing at the desired temperature and merge into large drops that can be easily separated by centrifugal extraction.usually for extra virgin olive oil extraction,the paste temperature is usually controlled around 25-30 ℃. |
|
E |
OLIVE OIL EXTRACTION PROCESS |
|
|
In this step,the ready olive paste is pumped into one decanter centrifuge to extract the olive oil by solid-liquid-liquid separation(3-phase) or solid-liquid separation(2-phase).Usually the vibration collection tank,piston pump,oil pump and screw conveyor are as part of this extraction system.Both 2-phase decanter and 3-phase tricanter is available for option according to your local requirements |
|
F |
OLIVE OIL PURIFICATION SYSTEM |
|
|
The olive oil coming from the decanter centrifuge still contains a certain amount of water and solids.the system consists of a disk stack centrifuge for final olive purification to remove residual water and solids.( a second disk stack centrifuge should be used to recover residual olive oil from the vegetation water flowing from the decanter.).We provide both popular type 1500/2000 separator and also modern type EVOS-Series separator for continuous olive oil production. |
|
G |
VIRGIN OLIVE OIL STORAGE |
|
|
The oil from separator will be pumped into sedimentation tank and stay for some time to remove the seldom moisture and impurities.after stay some time,the oil will be pumped into big stainless steel tank for storage,the tank should be avoid light and heat,constant temperature and nitrogen filling if necessary.
