a large possibility of variation in terms of capacity change and the necessary assembly work guaranteed at the construction site and at the same time a more precise control of the juice return ensures.

This object is achieved in that in the container an intermediate floor in the form of several identical sieve troughs that are directly adjacent and oriented in the conveying direction are arranged is and in each intermediate floor section a conveyor screw is provided and the lying close to each other over the entire width '' - the kit allows:

Assemble similar training to a system, the assembly effort is extremely low.

While so far the crushed and processed sugar cane (bagasse) in a large layer height treated and by means of heavy and robust drag conveyors through the leaching containers or troughs was promoted, according to the invention there is a departure from this type of treatment by now for the Transport of the bagasse screw conveyor in close arrangement side by side in connection with large area Containers are used through which the material is transported in a lower layer or bed height will. The screws, which are arranged close to one another, automatically ensure that the feed is uniform Material distribution over the entire width of the container or trough and thus also for an evenly distributed Load on the individual snails.

Because the individual screws are equipped with commercially available low-power drives can, in spite of the majority of the drive devices seen overall, there is a simplification because the problem of the heavy-duty drive that is otherwise required and operates at a low conveying speed and its disadvantages are avoided in the event of a defect in the drive device.

The screws can be produced with a relatively low weight and stored and guided in the associated sieve troughs in such a way that the wear is extremely low. Nevertheless, there is a reliable and constant cleaning of the sieve trays. Due to the lower weight and the low friction with the sieve surface, the screws can be driven with much less force. With the same width of the container, the effective sieve area in the subject matter of the invention is substantially larger than in the known devices of this type, since the sieve area is formed from a plurality of trough-like, ie concavely curved, sieve sections assembled to form an intermediate base. In terms of production, the effective conveying width of the arrangement can easily be adapted to the respective conditions in that more or fewer sieve trough sections with associated screws can be arranged laterally next to one another. By inserting vertical partitions and disconnectable drives, e ^; n and the same kit, change and adapt the respective effective working width of the container to the desired conditions. The kit can be used in a horizontal arrangement as well as in an arrangement inclined with respect to the horizontal, either on its own or in conjunction with several similar elements. In the latter case, each kit is expediently arranged inclined to the horizontal, the upper end or delivery end of one kit being connected to the lower or input end of the next kit via a chute.

The screw threads can be designed as sieve threads in order to minimize the juice flow Resistance r it ^ gen / iiM-t / en.

These clearing devices are expediently two or more on the shaft arranged curved removal arms.

With the B; According to the invention, any system with extremely little space requirements can be used create. Due to the larger sieve surface, a greater uniformity of treatment and a achieve more precisely controllable juice circulation. By gradual extension of the adjacent ones Troughs and augers can easily be changed in direction with the kits according to the invention to be implemented within a system without intermediate conversion devices. The kit enables large variations in capacity changes. The kits can be factory-made prefabricated so that only the finished screw assemblies have to be assembled at the construction site. As a drive Gear motors can be used for the individual screws. As different from drag chain drives with the new arrangement no chain weight needs to be conveyed and moreover the large friction on the sieve bottom caused by the chain weight is eliminated, but with the same performance can be worked with significantly reduced driving force.

The invention is illustrated below with the aid of schematic drawings of several exemplary embodiments explained in more detail. Show it

F i g. 1 shows a longitudinal section through a kit according to the invention in a first embodiment,

F i g. 2 shows a cross section through the delivery end of the kit according to FIG. 1,

F i g. 3 shows a cross section through a conveying area of the kit according to FIG. I and

F i g. 4 two of several kits arranged one behind the other according to FIG. 1 in a predetermined arrangement.

The kit of Fig. 1 comprises a horizontally arranged container 1 of substantially rectangular Cross-section. At the left end in Fig. 1, the container 1 has an upper inlet opening 2 for the Prepared material to be leached out according to arrow 3 from an upstream device is fed. At the other end of the container 1, an outlet opening 4 is provided on the underside which the leached in the container 1 good according to the arrow 5 in a further processing device or a conveyor is dropped.

In the container 1 an essentially horizontally arranged intermediate floor 6 is provided which extends over the entire width and over the entire length of the container 1 except for the ejection opening. As shown in FIG. 1 and 3, this intermediate base 6 is designed as a sieve base and consists of a plurality of sieve troughs 6a to 6e that are closely connected to one another and arranged next to one another in a horizontal plane and oriented in the longitudinal direction of the container 1. The intermediate floor can be formed from individual trough sections / together or in one piece. The troughs each have the same cross-sections, although in certain cases alternating cross-sections or radii of curvature can be provided.
