Plant and process for producing puree and/or juice with a high viscosity from a food product of vegetable origin

A plant for producing juice and/or puree from a food product of vegetable origin, said plant comprising:

• a treating section provided with an inlet for introducing a food product of vegetable origin and an outlet for discharging a treated food product of vegetable origin, said treating section being configured in such a way that the quantity of food product introduced through said inlet is equal to the quantity of treated food product discharged through said outlet, said treating section including:
• a fixed hollow body, or stator, having a substantially cylindrical or conical shape having a predetermined length (L) and provided with a treating surface;
• a first rotor also having a substantially cylindrical or conical shape, said fixed hollow body and said first rotor being configured in such a way that said treating surface is positioned at a first distance (d1) from said first rotor at an inlet end closer to said inlet less than, or equal to 100 mm, i.e. d1≤100 mm, and at a second distance (d2) with d2<d1, at an outlet end more distant from said inlet;
• a first driving group configured to cause said first rotor to rotate about a first rotation axis at a predetermined peripheral velocity (vT);
• a division section positioned upstream of said treating section and configured to divide a food product of vegetable origin into a plurality of pieces of determined size;
• and
• an extraction section positioned downstream of said treating section and configured to separate said treated food product of vegetable origin into a main product comprising said puree and/or juice and a waste product;
• wherein said division section is configured to divide said food product of vegetable origin into a plurality of pieces having at least a dimension with a length equal to, or less than, a said first distance (d1) between said fixed hollow body and said first rotor at said inlet end, in such a way to allow to easily introduce the pieces into said treating section.
