Abstract (Swedish)
The company QB Food Tech designs and installs powder in liquid
mixing systems for the food and pharmaceutical industries. The aim of
this master thesis is to develop a continuous blending system with
concentration output feedback for inline blending of complex products
starting from an existing batch process. A method for measuring a
substance concentration in flow‐rates therefore needs to be established.
The measured concentration signal is then used for controlling the
inflow rate of raw materials; a PID controller block is used for achieving
this task. The whole system is PLC controlled and programmed in
Siemens SIMATIC STEP7 software. An HMI operator‐panel enables
parameter adjustments and results of the monitored... (More)
