Addition to patent 559 ^ 2 - Addition to patent 559 ^ 2

The invention relates to a separating device according to patent No. 55942 for separating light particles from berries by means of an air flow, the device comprising a substantially vertical separating tube and a supply tube connected to said separating tube with supply devices. the lighter particles contained in the flow of material fed to the separation tube are separated by a bottom-up air flow through the separation tube and the heavier particles are pressed through the separation tube from top to bottom.

The object of the invention is to develop the above-mentioned device, in particular for berry cleaning, so that the use of the device, its adjustment and the monitoring of the adjustment can be carried out easily and simply.

With regard to the features characteristic of the invention, reference is made to the claims.

The invention is based on the use of a special separation chamber placed between the separation pipe and the vacuum piping. The separation tube 2 58447 «suitably protrudes a certain distance into the separation chamber from below. The vacuum piping joins the separation chamber resonantly from the side. The separation chamber is suitably at least partially, preferably completely transparent, so that the flow of the particles to be separated can be monitored visually. The pressure in the vacuum piping can be adjusted or the air flow can be adjusted in other ways according to the particle flow observed in the transparent separation chamber.

The separation chamber suitably consists of two parts, e.g. a top part and a bottom part, which can be detachably connected to each other. Thanks to the parts, the debris that accumulates in the separation chamber can be easily removed from the chamber.

The invention will now be described in detail by means of an exemplary embodiment with reference to the accompanying drawing, in which Figure 1 shows a perspective view of a separation chamber connected to a separation device according to the invention.

Figure 1 shows a separation chamber 11 connected to the separation device. The separation chamber 11 consists of a box-like member delimited by side walls, a top wall and a base 14. The separation chamber 11 is connected to the upper part of the separation pipe 1 of the separation device (not shown) by means of a connecting pipe 15. Further, a vacuum suction line 18 is connected to the separation chamber 11 via a connecting pipe 17.

The separating pipe 1 of the separating device, which is formed by the connecting pipe 15 of the extension, protrudes some distance, e.g. 1-2-3-4-5 cm, into the separating chamber 1 from below, through the bottom 13 of the chamber. The separation chamber 11 consists of detachably fastenable parts, a top part 12 and a bottom part 13. At the joint connection point 19 of the parts, the edges of the parts protrude partially so that the parts form a unitary, mainly fixed separation chamber.

The separation chamber 11 is suitably at least partially transparent, e.g. with respect to the upper part 12, so that in the cleaning of the berries the flow of particles formed by particles different from the berries is visible from outside the chamber. Thus, the device is suitable for monitoring the difference and adjusting the difference, e.g. by means of the air pressure of the vacuum piping or the control device of the separation device.

3 58447

When the device according to the invention operates in the separating pipe 1 and its connecting pipe 15, as well as in the vacuum piping 18 and its connecting pipe 17, a relatively fast air flow takes place. In the separation chamber 11, on the other hand, the velocity of the air flow is considerably lower, whereby the particles entrained with the air flow settle partially to the bottom of the separation chamber. The chamber is easy to empty and clean due to its two-part structure.

The exemplary embodiment is intended to illustrate the invention without limiting it in any way.
