The mobile classifier can be set up at different locations underneath silos. To perform its function, the mobile classifier is technically connected to stationary pipelines, filters and fans. ## Claims ### Claim 1 A device comprising a base frame (1) with an integrated working platform (2) with a traveling mechanism, the base frame accommodating at least the following dedusting components: a. a conical docking flange (3), free from any dead space, with quick-clamping devices (4) and an associated inlet funnel (5) with a shut-off flap (6); b. a wind classifier (7); c. an intermediate container (8) as a recipient vessel; d. a telescopic pipe (9) with an initiator (10) at a conical outlet flange (11); c. an intake filter (12) with a supply-air fan (13); and f. an exhaust-air pipe docking means with a lifting device (14) and an initiator (15). ### Claim 2 (depends on 1) The device according to claim 1, wherein all component parts that come into contact with product are structurally designed to be free from dead space. ### Claim 3 (depends on 1) The device according to claim 1, wherein the working platform (2) is equipped with a climbing ladder, a device for docking onto a silo outlet (17), a device for connecting the exhaust-air line (14) and a device for plugging in a coded connector (18). ### Claim 4 (depends on 1) The device according to claim 1, further comprising a local control unit (16) for regulating the rate of the air supplied and allowing the classifier to operate. ### Claim 5 (depends on 1) The device according to claim 1, wherein an automatic location identification on the basis of a coded E-type connector (18) is performed for each silo, filled from a silo outlet to the classifier inlet when docking the classifier. ### Claim 6 (depends on 1) The device according to claim 1, wherein a data transfer between a local control and a higher-level central control takes place via a wireless network (WLAN). ### Claim 7 (depends on 1) The device according to claim 1, further comprising a lifting mechanism, including two adaptation arms (22), with interlocking and frictional engagement onto the frame of the classifier, the lifting mechanism being adapted to allow connection of a small tractor (21) to the device. ### Claim 8 (depends on 1) A method for classifying granules, comprising classifying granules using the device according to claim 1. ### Claim 9 (depends on 8) The method for classifying granules according to claim 8, wherein the amount of granules supplied is stopped by the shut-off flap (6). ### Claim 10 (depends on 9) The method for classifying granules according to claim 9, wherein a rate of granules flowing out in the filling process, inflow metering to the classifier is controlled by closing the shut-off flap (6) by means of a filling-rate monitor in the recipient vessel (8). ### Claim 11 (depends on 1) The method for cleaning a device according to claim 1, wherein a flap (20) in a supply-air pipe is closed during flushing. ### Claim 12 (depends on 11) The method for cleaning a device according to claim 11, wherein the flap (20) in the supply-air pipe is initiator-monitored. ### Claim 13 (depends on 11) The method for cleaning a device according to claim 11, further comprising drying the complete device by introducing compressed air.
