Sieving device for a juicing plant

The invention relates to a screening device for a juicing system.

Juicing systems, for example for oranges, are well known. Individual oranges are fed into the juicing system, which are automatically divided and then squeezed. Customers often want only a very specific amount of pulp in the juice to be served. In this respect, it is well known to run the squeezed juice through a sieve.

However, a conventional sieve with a net-like sieve has the disadvantage that it clogs up relatively quickly due to the pulp. In addition, such a sieve has the disadvantage that the amount of pulp that should remain in the juice cannot be determined by the sieve. This means that there is juice with or without a full pulp content.

The invention is therefore based on the object of providing a sieving device for a juicing system which, on the one hand, no longer clogs and, on the other hand, makes it possible to leave a very specific amount of pulp in the pressed juice.

The object is achieved according to the invention in that two rotating axes arranged parallel to one another are provided, by which several belts arranged parallel and at a distance from one another are held. The distance between the belts can in principle determine how much pulp remains in the pressed juice and how much is carried away to the side by the belts. This means that by increasing the distance, the proportion of pulp in the juice increases, whereas if the distance is smaller, the proportion of pulp in the juice decreases.

In order to prevent the distance between the belts from changing during operation, it is provided that the distance between the belts can be set on at least one axis. This can be done, for example, by having at least one of the axes have a toothing running parallel to the longitudinal axis of the axis in order to guide the belts - as already explained - at a distance from one another on the axis.

According to a further feature of the invention, the screening device has a scraper plate to remove the

to strip off any fruit pulp that has accumulated. The scraper plate is arranged at the end of the sieve device, as seen in the conveying direction of the belt. The scraper plate advantageously has a toothing at its end facing the belt, so that the scraper plate can engage in the gaps between the individual belts.

Beneath the sieve device, a funnel for collecting the juice is advantageously provided, which has a tap for discharging the liquid. 10

The invention also relates to a juicing system with a sieving device according to one or more of the features described above.

The invention is explained in more detail below with reference to the drawings.

Figure 1 shows the juicing system in perspective;

Figure 2 shows a top view of the screening device;

Figure 3 shows a view along the line III - III of Figure 2;

Figure 4 shows the arrangement of the scraper plate on the

Sieving device.

The juicing system, designated as 1, shows the sieving device, designated as 10, under the juice outlet opening 2. The sieving device, designated as 10, consists of a rectangular box 11 with a funnel 12 arranged on the underside with a tap 13. The rectangular box 11 accommodates the two axes 20 and 21 in a rotatable manner.

, with the drive being via the axis 20. Between the two axes 20 and 21 there are the belts 25 arranged parallel to each other on the two axes. A gap 26 is provided between the belts 25, with this gap 26 ensuring that a certain amount of pulp can pass through, while another part of the pulp is transported away by the belt in the conveying direction (arrow 30).

The axes 20, 21 have a toothing 22, which ensures that the individual belts 25 are actually received by the axes at a predetermined distance from one another.

Furthermore, a scraper plate 40 is provided. The scraper plate ensures that the pulp conveyed on the belt can be separated.

Claims (10)

1. Sieving device ( 10 ) for a juicing plant ( 1 ) , characterized by two rotatable axes ( 20 , 21 ) arranged parallel to one another, by which a plurality of belts ( 25 ) arranged parallel and at a distance ( 26 ) from one another are held. 2. Screening device according to claim 2, characterized in that at least one of the axes ( 20 ) is drivable. 3. Screening device according to claim 1, characterized in that the distance ( 26 ) of the belts ( 25 ) on the at least one axis ( 21 ) can be fixed. 4. Screening device according to claim 3, characterized in that at least one of the axes ( 21 ) has a toothing ( 22 ) running parallel to the longitudinal axis of the axis in order to guide the belts ( 25 ) spaced apart from one another on the axis ( 21 ). 5. Sieving device according to claim 1 or 3, characterized in that the sieving device ( 10 ) has a scraper plate ( 40 ) in order to scrape off the pulp accumulating on the upper side of the belt. 6. Screening device according to claim 5, characterized in that the scraper plate ( 40 ) is arranged at the end of the screening device ( 10 ) as seen in the conveying direction of the belt ( 25 ). 7. Screening device according to claim 4 or 5, characterized in that the scraper plate ( 40 ) has a toothing ( 22 ) at its end facing the belt ( 25 ). 8. Sieving device according to claim 1, characterized in that a funnel ( 12 ) for collecting the juice is arranged under the sieving device ( 10 ). 9. Sieve device according to claim 8, characterized in that the funnel ( 12 ) has a tap ( 13 ) for discharging the liquid. 10. Juicing system ( 1 ) with a screening device ( 10 ) according to one or more of the preceding claims.
