Dry cleaning of containers – a clean solution

Dry cleaning – environmentally friendly and effective

The ingenious design makes it possible to automatically clean containers that have been contaminated inside with product residue and dust. Thanks to the umbrella-like mechanism, it is also possible to clean containers with small inlet apertures, as the cleaning unit only unfolds once it is inside the container. The design can thus be adapted to virtually any geometric shape of rotationally symmetrical hoppers.

Water is frequently used for cleaning containers. This necessitates expensive washing chambers and drier units, which need to be installed in separate parts of the building. Therefore, wet cleaning results in the containers being out of production for a longer time in order to carry out the cleaning and subsequent drying processes. In most cases, however, dry cleaning the containers is totally sufficient to remove any product residue reliably. This type of cleaning provides quite a few advantages if contrasted with wet cleaning. Since no water is used, the station can be installed directly in production. The outcome is shorter transport distances for hoppers and in addition there is no need for time-consuming drying processes.

Collapsible and robust

The cleaning unit is attached to a vertical pillar with a cantilever bracket and can be moved in a vertical line with a linear drive. The cleaning unit consists of two arms where the cleaning jets are attached. These arms are folded together tightly as the cleaning unit is inserted into the container and they do not open out until fully inserted in the container. Once unfolded, the unit is rotated during the cleaning cycle via a pneumatic rotary drive. This enables it to reach all points on the inside of the container and to purge them with compressed air. The nozzles have a central supply of cleaning air via pneumatic hoses that run in a flexible energy supply chain.

The container that is being cleaned, and which is usually fitted with a manually operated outlet valve, is deposited by a lifting truck onto the station for cleaning or is conveyed to the station automatically. Centring corners make it easier to position the container. A dust-tight connection is generated between the container outlet and the suction hopper with the aid of the patented docking collar. An exhaust for suction is connected to this hopper via a central filter station, which extracts product residue and dust particles that accumulate during the cleaning cycle. The container’s outlet valve can be opened and closed manually or automatically, depending on the model.

Ranging from manual to fully automatic

If a container needs to be cleaned as a result of a changeover in products or due to a set cleaning interval, it is removed from production and placed on the cleaning station. The station is now in its starting position, i.e. the linear drive with the attached cleaning unit is in the upper end position and the rotary drive is in the starting position.
