The subject of the invention is a chamber apparatus for leaching sugar-containing Plant cuttings.

This apparatus consists in a known manner of an inclined trough in which the juice from the upper to the lower end is fed through an agitator and transport mechanism Flows counter to the pulp conveyed at the top, the pulp through transfer devices from each chamber to the next higher one separating the individual chambers Part of the trough cross-section, leaving free partitions, are thrown.

Practice has shown that such apparatus does not leach sufficiently evenly the schnitzel is to be obtained; in particular, it occurs in the case of substantially different specifics Weight of the juices and schnitzel often only leach the schnitzel in layers.

According to the invention, this Ubelstand is to be avoided in that the juice is forced is to flow through the individual chambers not only in the longitudinal direction, but the schnitzel also obliquely upwards in the diagonal direction of each in the chamber to flow through the schnitzel mass. The individual leaching chambers are used for this purpose separated by so-called reversal chambers, in which the juice is not but the schnitzel can enter. These chambers are therefore called reversal chambers because the juice enters them at the top to exit again at the bottom, the chambers so serve to keep the juice from the upper end of a leaching space lower end of the next to convey. As a result of this arrangement, the way of the juice becomes not insignificantly enlarged by the pulp masses and thereby the leaching improved. A further improvement in this sense is ensured by the fact that by virtue of the reversal chambers between each two successive leaching chambers juice and schnitzel completely separated from each other , it is therefore prevented that the schnitzel always adheres to them with the same Stay in touch with the juice layer.

The reversing chambers are particularly advantageous by joining chambers in a V-shape at the top Walls formed, one of which is perforated at the top and the other at the bottom. With this type of construction exists for the chips, which are passed through the throwing devices via the reversing chambers are thrown away, no way to stay where they are, they just roll Down the roof-shaped sloping walls of the reversing chambers unhindered down into the next chamber.

The subject of the invention is shown in an exemplary embodiment in the drawing shown schematically.

Fig. Ι is a longitudinal section,

FIG. 2 shows a section through the trough alone along line AB in FIG. 1.

is divided into a number of discharge chambers d and reversal chambers e. The partition walls b and c are brought together obliquely V-shaped upwards and end below the drive shaft f, which runs through the trough to its full length. The walls b are perforated at the lower end at g "and the walls c at the upper end at h. The feed channel i is provided for the inlet of the cossettes; The incoming chips are transported upwards in the individual chambers d by the correspondingly inclined transport arms k, which are only shown in the left half of FIG Upper thrower I, which are also only shown at the ends of the trough, are thrown over the apex of the V-shaped walls b, c into the next chamber d. The liquid, juice or water supplied through the pipes m, which is used for leaching, flows towards them. This juice flows in the sense of the arrows drawn in the right half of FIG deeper chamber and so on, whereby, as indicated by the straight arrow drawn in the penultimate chamber d, the chip mass heaped up in the chamber not only in the longitudinal direction of the trough, but also in the diagonal direction from below to above moved through it and within the reversal chambers e is completely separated from the chips thrown over these chambers. ■ The leached chips are from the ^ last chamber d at the right end of the trough by a transport device in the form of the screw η ο. Like. Conveyed into the tube 0, from which they can be moved by any subsequent transport members. The juice obtained flows through the pipe p for further production. The juice still flowing out of the chamber d located furthest to the right is again transferred into the leaching through the pipe q in the sense of the arrows connected to it by means of the pipes m. Of course, the walls b and c could also meet in a U-shape instead of a V-shape; moreover, several of the new devices could be connected in series. Godfather ν t-An Proverbs: 1. Apparatus for leaching sugar-containing cuttings, in which the Juice and the schnitzel are fed in countercurrent through individual leaching chambers, characterized in that the latter are separated from one another by walls, the one Include space in which the juice enters separately from the schnitzel at the top exit below, so that at the end of each leaching chamber juice and schnitzel are separate and the juice all obliquely from the bottom to the leaching chambers flows through above. 2. Apparatus according to claim 1, characterized in that the reversing chambers be formed by walls colliding in a V-shape at the top, one of which is perforated at the top and the other at the bottom. 1 sheet of drawings.
