Mann+Hummel Protec: Visualisation software for easy dryer control

Overview screen of the new visualisation software.

With the new MH 25 Somos Control MTA visualisation software, the dry air dryer and the connected drying hoppers, with their volumes adjusted to the corresponding processing process, can be centrally monitored and controlled. This standard software has been designed for the monitoring of a modular hopper installation consisting of up to 12 drying hoppers whose control also runs a conveyor for the filling of the hopper and up to 12 conveyors on the processing machines. If, for example, the processing parameters change, the operator can easily access and accordingly align all individual controls from a central location The individual operation of each drying system unit with the associated material handling up to the processing machines would not only be very time-consuming but also harbours a significant potential for error.

Comfortable system operation
The new Windows-based visualisation software offers functionality comparable to a powerful SPS, however at a much more affordable cost/benefit ratio. These advantages become evident not least if the processor gradually upgrades the drying system in the course of a production expansion. With the additional module hopper connected via the standard plug and socket, the visualisation software automatically recognises the new component assembly and the drying hopper is operational.

Parameters the system operator may not change are accessible by password entry only.

Each time the software is started an automatic scan of all interfaces recognises which units are currently in operation. At this level, the possibility also exists to individually name the devices, to align them according to one´s own criteria and to set the required language. From the overview screen displaying all devices and their statuses the operator can switch over to the device´s operational side with a click on the device. Here he can enter the relevant material and process parameters. In configuring the D dryer, some other parameters that the machine operator is not allowed to change are locked and only authorised for persons with a password. Any questions on the operation of the machines can be quickly answered with the directly accessible online operating manual.

The possibility to record the dryer and hopper temperatures is particularly helpful for monitoring, documentation and traceability of the production process. For this, the supply and return air temperatures of all active drying hoppers and the dryer are stored as CSV files with date and time. The operator can, for example, display the temperature curve of a device for any time period also as a line graph from this.
