Abstract
A process that is capable to optimize the efficiency of extraction at room temperature of juice or puree from food pulps of fruit and vegetables, responsive to the consistency of the same. In a first step the pulps are cut and softened in a first section (4) of the machine, where a first rotor (5) applies to the food pulps a plurality of pulses in quick succession against a stator that has protrusions on the inner surface. The softened product then passes through a second section (6), where the separation is carried out of the part of pulp that can be used (juice or puree), which are conveyed in a outlet duct (11), from the waste solid parts (peelings, seeds, hard fibres), which are disposed through an outlet (13). The rotors (5, 7) are not mounted on a same shaft, but on different shafts (8, 18) operated by respective motors (9, 19). Both motors (9, 19) are operatively connected to a device (20) that controls the respective speeds in a manual way, for example by a speed variator, or automatically, responsive to predetermined input parameters, relative to the consistency of the product.
Description
- The present invention generally relates to machines for the food industry and specifically it relates to the extraction of juice and puree from vegetable or animal food.
- In particular, the invention relates to a process for optimizing the efficiency of extraction at room temperature juice or puree from said food.
- As known, a variety exists of types of rotating machines (rough and fine extractors) for obtaining juice and puree mainly from vegetable food, fruit and vegetables, but also from animal food, meat and fish.
- Normally, in a first step the product to treat is previously softened or chopped, more or less finely, for then being put in an extracting machine in a second step. The extracting machines of prior art are made up essentially of a fixed structure that comprises a perforated sheet of cylindrical or conic shape, also called screen, and a bladed rotor that rotates inside. The rotor is fitted on a shaft which rotates quickly driven by a motor. In particular, the chopped or softened product by centrifugal force is pushed radially and continuously against the screen. This way the product passes through the screen thus extracting the mostly liquid part that is conveyed for being then subject to further treatments. The solid part that do not pass through the screen, instead, is pushed axially opposite to the input and is automatically conveyed to an unloading section as waste to dispose. See on this subject IT1199392.
- A known process of this kind is the extraction at room temperature that is carried out in two steps: in a first step the food pulps is softened by a plurality of pulses in quick succession and in a second step, which is carried out in an extracting apparatus as above described, the useful part (juice or puree) is separated from the waste solid part.
- In room temperature extraction softening is obtained by pulses in quick succession produced by a cylindrical or conical body (stator), which has a plurality of protrusions on the inner surface, associated to a bladed rotor that turning in the stator pushes the food pulps by centrifugal force against the protrusions of the stator, giving rise to the softening. See on this subject IT1249363.
- When extracting at room temperature, according to the above described prior art, the softening and extracting steps are gathered in a single compact working unit having a single motor: the respective rotors are mounted on a same axis and so rotate at a same speed. In this connection see hereinafter
FIG. 1 and the relative description. - Such a unit gives good results for all those vegetables that, owing to a low consistency of their pulp (i.e. apples, peaches, pears, apricots), can be easily softened, but are less suitable for products having higher consistency (i.e. carrots, quinces, etc.) that require a stronger softening action to reach an optimal efficiency in the following extraction step.
- The most effective way to boost the softening rate is to increase the speed of the respective rotor to obtain a double effect of having more pulses and at the same time to give each pulse a higher energy.
- However, a higher speed of the rotor of the extracting apparatus different from the optimal can be problematic, both because the fraction of liquid and solid parts changes, and because the mechanical parts can be stressed in an incorrect way.
- For this reason, the difficulty to soften certain fruit and vegetables having fibres of high consistency causes such fruit and vegetables to be scarcely used for juice or puree.
- An opposite problem arises with products having a very soft pulp, for example watermelons, for which the softening step has to be very short and not much energetic, i.e. with low speed of the rotor, whereas the step of extraction can be carried out with much higher speed.
- It is therefore a feature of the present invention to provide a process that is capable to optimize the efficiency of extraction at room temperature juice or puree from food pulps of fruit and vegetables, responsive to the consistency of the same, without encountering the above drawbacks.
- It is another feature of the present invention to provide a machine that carries out this process.
- These and other objects are accomplished by the process for optimizing the extraction at room temperature juice or puree, from food pulps of fruit and vegetables having a predetermined consistency, by a machine having:
-
- a softening section of the food pulps having at least a first stator and a first rotor, the first rotor rotating at a first speed:
- an extracting section having at least a second stator and a second rotor, the second rotor rotating at a second speed,
- speed adjusting means operatively connected to rotors driving means,
- wherein the steps are provided of
-
- actuating the rotors driving means by said speed adjusting means according to a predetermined ratio between the first and the second speed responsive to an input parameter relative to the consistency of the food pulps.
- In a possible exemplary embodiment said speed adjusting means comprise means for receiving an input parameter through a processor, and the steps are provided of:
-
- communicating to the processor an input parameter relative to the consistency of the food pulps;
- actuating the rotors driving means according to a predetermined ratio between the first and the second speed responsive to the input parameter.
- According to another aspect of the invention, a machine for extracting at room temperature juice or puree from food pulps of fruit and vegetables having a predetermined consistency comprises:
-
- a softening section of the food pulps having at least a first stator and a first rotor, the first rotor rotating at a first speed:
- an extracting section having at least a second stator and a second rotor, the second rotor rotating at a second speed,
- a first motor for causing the first rotor to rotate at the first speed,
- a second motor for causing the second rotor to rotate at the second speed,
- a device for adjusting the speed and the efficiency of the machine having speed adjusting means operatively connected to the first and the second motor, whereby it is possible to operate the rotors driving means by said speed adjusting means according to a predetermined ratio between the first and the second speed responsive to an input parameter relative to the consistency of the food pulps.
- In a possible exemplary embodiment, said speed adjusting means comprise means for receiving an input parameter through a processor, and means are provided for setting in said processor an input parameter relative to the consistency of the food pulps, said rotors driving means according to a predetermined ratio between the first and the second speed responsive to the input parameter.
- Alternatively, the speed adjusting means are means operated manually selected from the group: frequency variators, mechanical gearboxes.
- In a first exemplary embodiment of the invention the first and the second motor have axes shifted from each other.
- In a second exemplary embodiment of the invention the first and the second motor are coaxial.
- Preferably, the first rotor is mounted on a first shaft and the second motor is mounted on a second shaft, wherein said first and second shaft are coaxial and pivotally engaged a within/on another, whereby they are capable of having speed independent from each other and of holding with respect to each other workloads.

first section 4 as whole fruit or large parts, co-axially and upstream from the rotor is mounted a rotating cutter comprising a plurality of knives suitable for chopping the product in smaller parts. - The softened product, exiting from
first section 4, then passes through asecond section 6, where the separation is carried out of the target parts of pulp (juice or puree), which are conveyed in anoutlet duct 11, from the waste solid parts (peelings, seeds, hard fibres), which are disposed through anoutlet 13.
