For example The separation bottom has a sawtooth cross section.   The separating bottom has, for example, a curved notch in the transition to the bar sieve. to this Advantageously, therefore, a wire cotton such that the coarse residue is caught on the tip of the separation bottom The inclusion of debris is prevented.   In another embodiment, between the fine residue discharge and the coarse residue discharge Smooth separating walls are arranged. This also prevents metal wire scrap from being caught The advantage is that there is no.   For example, two controllable vibration generators are attached to the transport device. For example, both The rotation speed of the vibration generator is made different.   According to the unloading device according to the present invention, a transfer device equipped with a vibration generator is employed. Plugs in the residue discharge pit To prevent air oxygen from entering the low-temperature carbonization device better than before. Another advantage is obtained. In particular, coarse residues are now possible from fine residues The advantage is that the separation is clearly better than it was.   The above combination of a grooved separation bottom and a rod-shaped sieve separates or purifies other substances. Can also be used.   Hereinafter, a takeout apparatus according to the present invention will be described in detail with reference to the drawings.   FIG. 1 is a schematic sectional view of a take-out device according to the present invention,   FIG. 2 is a cross-sectional view of a grooved separation bottom,   FIG. 3 is a plan view of a grooved separation bottom in which a rod-shaped sieve is integrally formed.   FIG. 1 shows a housing 1 of an unloading device.
