A plant for producing juice and/or puree from a food product of vegetable origin, said plant comprising:
- a first extraction section configured to subject said food product to a first extraction operation the first extraction section including:
- an inlet for introducing said food product;
- a first rotor operatively connected to a first drive motor arranged to cause said first rotor to rotate about a first rotation axis at a first predetermined angular velocity (ω1);
- and
- a first sieve provided with a plurality of holes and arranged to be positioned externally to said first rotor, said food product being forced by said first rotor against said first sieve in such a way to divide the same into a first extracted food product comprising said puree, or juice, which passes through said first sieve and is discharged through a first outlet, and in a first waste product which, instead, does not pass through said sieve and is discharged through a second outlet;
- and
- a second extraction section positioned downstream of said first extraction section, said second extraction section being configured to subject an entering product to a second extraction operation the second extraction section including:
- an inlet for introducing said food product;
- a second rotor operatively connected to a second drive motor arranged to cause said second rotor to rotate about a second rotation axis at a second predetermined angular velocity (ω2);
- and
- a second sieve provided with a plurality of holes and arranged to be positioned externally to said second rotor, said introduced food product being forced by said second rotor against said second sieve in such a way to divide the same into a second extracted food product comprising said puree, or juice, which passes through said second sieve and is discharged through a first outlet, and in a second waste product which, instead, does not pass through said second sieve and is discharged through a second outlet;
- wherein:
- wherein a treatment section is furthermore provided positioned between said first extraction section and said second extraction section and comprising an inlet for introducing said first extracted food product, and an outlet for discharging a treated product arranged to be fed into said second extraction section,
- said treatment section is configured in such a way that the quantity of the food product entering the treatment section is equal to the quantity of treated product exiting the same, and
- said treatment section includes a fixed hollow body cylindrical, or conical shaped within which a third rotor is positioned also this cylindrical, or conical shaped in that said third rotor is operatively connected to a third drive motor configured to cause said third rotor to rotate about a third rotation axis at a third predetermined angular velocity (ω3) in that said third predetermined angular velocity (ω3) is greater than both the first predetermined angular velocity (ω1) and the second predetermined angular velocity (ω2), and in that said third predetermined angular velocity (ω3) is less than 8000 rpm, in such a way that said second extracted food product has a high viscosity.
