Abstract

Device for cleaning the filter pipes used to extract fruit juice, consisting of a cylindrically shaped tube (1) that runs telescopically through the inside of the filter pipe (2), and some circumferential openings (3) have been made at one end of this interior tube (1) through which previously injected pressurized air is expelled along its entire length. The interior tube (1) includes an air inlet (5) that has been provided at one end, and this air inlet (5) is connected to a surrounding chamber (6) with the same configuration as the interior tube (1) and in turn is connected to the openings (3) that this tube has at its other end for cleaning the filter pipe (2).

Description

DEVICE FOR CLEANING THE TUBES FILTER FOR THE EXTRACTION OF FRUIT JUICES DESCRIPTION OBJECT The object to which the invention that is protected in the present patent consists of a "Device for cleaning the filter tubes for the extraction of fruit juices", which allows the extraction of fruit juices in conventional machines without need to interrupt the process every so often.

BACKGROUND The known process for the extraction of fruit juices, especially citrus fruits, consists in the introduction of the fruit in a machine that fulfills said function. To do this, the fruits are channeled and pushed by means of forks to cups that receive the fruit, so that the fruit remains deposited in them. At the same time, in this machine, other upper cups have been arranged vertically aligned with the cups that receive the fruit, and when they move vertically they imprison it.

Next, a cutter makes a circular incision in the upper and lower part of the fruit, to allow the juice to exit through a filter tube, located inferiorly to the cups, towards a juice collector SUMMARY Device for cleaning the filter tubes for the extraction of fruit juices, constituted by a tube (1) of cylindrical configuration that runs telescopically inside the filter tube (2), so that said inner tube (1) is they have made holes (3) surrounding and at one end thereof, which throughout their travel expel air pressure previously injected. The inner tube (1) incorporates an air inlet (5) which is provided in. one end thereof, said air inlet (5) being connected to a surrounding chamber (6) and of the same configuration as the inner tube (1), and connected in turn to the holes (3) that for cleaning the Filter tube (2) incorporates this one at its other end. when the upper and lower cups compress and squeeze the fruit.

The filter tube where the juice of the fruit enters has holes in all its surface that become clogged because the pulp of the fruit adheres to them. For this reason it is necessary to stop the machinery every certain time (approximately every 6 or 7 hours) to clean the filter tube, thus reducing the performance and the autonomy of said machinery.

DESCRIPTION OF THE INVENTION The purpose of the invention that constitutes the object of the present patent consists in the elimination of the structural and functional drawbacks of the known object, having been designed and developed according to this priority objective.

The device object of the Patent is constituted by a tube of cylindrical configuration that runs telescopically inside the filter tube, so that in said inner tube have been made holes surrounding and at one end thereof, which throughout their travel expel pressure air previously injected.

Although the injection of air has been foreseen, inside the inner tube can be injected any type of fluid that fulfills the same function, and that manages to keep all the holes of the filter tube clean, expelling all the impurities that in the process of their normal phase adhere to them and that the filter tube has in its entire surface.

In this way, there is an automatic cleaning of the filter tube, which allows its uninterrupted work during the work cycle of the machine. In addition, it is achieved that the performance of said machinery increases considerably and a consequent improvement of its autonomy.

BRIEF DESCRIPTION OF THE DRAWINGS To complement the description of the invention and to facilitate the interpretation of the structural and functional characteristics of its object, drawings are attached in which a preferred embodiment of the device for cleaning the filter tubes for the extraction of fruit juices is represented schematically. constitutes the object of the present Patent. In said drawings: - Figure 1 shows a section of the assembly formed by the filter tube and the inner tube for cleaning. Figure 2 shows a detail of the orifices of the filter tube and its communication with the orifice through which it leaves the air under pressure. - Figure 3 illustrates a section of the inner tube that runs inside the filter tube.

DESCRIPTION OF A PREFERRED EMBODIMENT In order to clearly show the nature and scope of the advantageous application of the device for cleaning the filter tubes, which constitutes the object of the claimed invention, its structure is described below with reference to the drawings which, because they represent a preferred embodiment of said object, for informative purposes, should be considered in its broadest sense and not as limiting the application and content of the claimed invention.

The device (1) for cleaning the filter tubes for the extraction of fruit juices is constituted by a tube (1) of cylindrical configuration that runs telescopically inside the filter tube (2), so that in said inner tube (1) Surrounding holes (3) have been made and at one end thereof, which during their entire travel expel air under pressure, expelling impurities adhered in the holes (4) 'that includes the filter tube on its entire surface ( 2) .

The pressurized air inlet (5) is provided at one end of the inner tube (1), so that it is connected to a surrounding chamber (6) and of the same configuration as the inner tube (1), connected in turn with the holes (3) that for the cleaning of the filter tube (2) incorporates the inner tube (1) at its other end.

Although the injection of air has been foreseen, inside the inner tube (1) could be injected any type of fluid that fulfills the same function, and that manages to keep all the holes (4) of the filter tube clean, expelling all the impurities that in the process of their normal phase adhere to them and that the filter tube (2) has in its entire surface.
