Machine for extracting puree, or juice, from food products

Method for adjusting the position of a sieve in a machine for extracting puree, or juice, from a food product, said method comprising the steps of:

• providing a machine for extracting puree, or juice, from a food product comprising:
• a machine body having an inlet for introducing the food product;
• an extraction section configured to separate, during an extraction configuration, said food product into a main product comprising said puree, or juice, and a waste product, within said extraction section a sieve having a cylindrical, or conical, shape being mounted and provided with a plurality of holes, and a rotor having cylindrical, or conical, shape positioned within said sieve and configured to rotate about a rotation axis in such a way to apply a centrifugal force on said food product to force the same against said sieve and separate the same into said main product, which passes through said holes of said sieve, and is discharged through a first outlet, and said waste product, which, instead, does not pass through said holes of said sieve and is discharged through a second outlet positioned downstream of said first outlet with respect to the advancing direction of the food product in said extraction section;
• a motor operatively connected to said rotor and configured to cause said rotor to rotate about said rotation axis;
• a displacement step is, furthermore, provided to move said sieve with respect to said machine body along a longitudinal direction in a first and a second displacement directions to position said sieve in a determined working position (Pe) when said extraction section does not work in said extraction configuration, said determined working position (Pe) being positioned between a predetermined first limit position (P1) and a predetermined second limit position (P2).
