Downstream of the inlet, an extraction section is provided comprising a sieve with a plurality of holes, and a rotor configured to rotate about a rotation axis, operated by a motor through a motor shaft, to apply a centrifugal force to the food product to cause the same to be separated into a main product, comprising the puree, and/or the juice, which passes through the holes and is discharged from the extraction section through a first outlet, and a waste product comprising the skins, and the seeds, which, does not pass through the holes of the sieve, and is discharged through a second outlet. Further, a displacement device is configured to move the sieve with respect to the machine body along a longitudinal direction.

Abstract: A machine for extracting puree, or juice, from a food product of vegetable origin comprises a hollow body having a longitudinal axis and an inlet for introducing the food product. In the hollow body a first extraction section and a second extraction section are provided both having, respectively, a sieve and a rotor coaxially positioned within the sieve and having a plurality of blades. The rotors are caused to rotate by a respective driving group in order to subject the treated product to a centrifugal force. In this way, in the first extraction section the division of the product is caused in a first portion, which passes through the sieve, and in a second portion, which does not pass through the sieve and advance along the hollow body up to reach a passage section and, therefore, to enter in the second extraction section.

Abstract: A process for optimizing the efficiency of extraction at room temperature of juice or puree from pulps of fruit and vegetables, responsive to their consistency. The pulps are first cut and softened in a first section of the machine, where a rotor applies pulses to the pulps in quick succession against a stator having protrusions on the inner surface. The softened product then passes through an extraction section, where the separation is carried out of a main product, which is conveyed in an outlet duct, from the waste solid parts, which are discharged through an outlet. The rotors are mounted on different shafts operated by motors. Both motors are operatively connected to a device that controls the speeds manually, or automatically, responsive to predetermined input parameters, according to the consistency of the product.

Abstract: An apparatus for removal of waste material in a process for extracting puree, or juice, from a starting product based on vegetable or animal food including a step of feeding a measured amount of starting product to a machine for extracting puree. The starting product can be pre-treated, for example softened, and then subject to an extraction step, obtaining a main product including the puree, which is discharged via a first outlet, and a waste material that is discharged via a second outlet. The waste material is then mixed with a measured amount of a liquid, for example water, obtaining a heterogeneous mixture. The heterogeneous mixture can be thus easily removed by suction, for example by a hydraulic pump connected to the second outlet, to be quickly withdrawn from the extraction section avoiding the risk of jamming the machine at the second outlet.
