Adaptive control program optimises processes in compound feed plant

Efficient production of feed for farm animals

Cost pressure in the market for meat and dairy products is increasing. This also raises manufacturers’ interest in lowering energy consumption for the production of feed for cattle, pigs, and poultry. The BINE-Projektinfo brochure “Producing animal feed with less electricity and heat” (07/2014) presents the optimised production process for a compound feed plant. A computer-aided control program allows the energy-efficient processing of different batches of natural raw materials into a compound feed with a specified ratio of fats, proteins, and trace elements.

Milling, mixing, pressing and pelletising are the central processes in the production of animal feed. Energy accounting of these processes marked the beginning of this research project. In a next step, the scientists developed a measurement instrumentation that is integrated into the production process while continuously displaying the current quality data of the 12 to 18 feed ingredients used. A computer-aided and adaptive expert system gives real-time recommendations on process control.

While feed producers were previously solely dependent on the knowledge and experience of long-term employees, the new control program now acts as an assistant. With the now optimised processes, that part of the energy used as a measure of caution to ensure the expected product quality can now be saved. This research project was conducted by researchers at the Institute for Integrated Product Development at the University of Bremen in collaboration with the company Austing Mischfutterwerk GmbH & Co. KG.
