SPANGLER – The Plus in Process Reliability.
For BHS-Sonthofen, a specialist in recycling, construction materials, and process technology solutions, we developed a modern control solution for a vertical dryer (an industrial drying system used for drying bulk materials or pasty substances, e.g., in the food, chemical, or pharmaceutical industry), which stands out for its exceptional efficiency and adaptability.
Advanced Control for Maximum Efficiency
The control system we designed and built consists of two cabinet sections. The core component is a frequency converter with a power rating of 90 kW, which drives the mixing spirals in the vertical dryer. This frequency converter plays a key role in the high efficiency of the drying process, as it enables precise control of the mixing motions while also saving energy.
Since the system operates in a potentially explosive (Ex) environment, we met strict safety requirements. The control cabinet itself is located outside the Ex area, while the locally installed operator panels comply with the standards for Gas Zone 1 and Dust Zone 21. This means the specially manufactured stainless steel operator panels are designed to provide maximum protection in the event of an explosive atmosphere. The special enclosures for this project were supplied by explosion protection expert Exepd to meet the high safety demands. The local operator interface allows specific process requirements to be addressed directly during operation, ensuring a high level of safety and process control.
Adaptable Automation for the Process Technology Market
The dryer itself is designed to efficiently dry various media while ensuring uniform temperature distribution and consistent moisture levels. With its double-walled, conical containers and a central agitator, the material is continuously mixed to allow even heating and drying.
This automation solution enhances process stability and reduces drying times – resulting in a significant increase in production capacity for the end customer.
