DRIVES, CONTROLS & MOTORS PRODUCTS DRIVE KEEPS THE DRINKS FLOWING
From its facility in Shepton Mallett, contract packing company Framptons processes around 1.5million litres of fruit juices and milk-based drinks each year. The company, however, needed to find a drive to replace an obsolete unit, but the new one needed to fit into the existing cabinet. ABB Value Provider APDS recommended the
ACS480 general purpose drive from ABB. Being compact and with a low power rating range (0.75
to 22kW), this is an ideal fit for the size of fans, pumps, mixers, conveyors, and compressors most commonly found in the food and beverage industry. The drive is facilitating more consistent end-product quality by
applying closed loop control to the blending process. As the soft water pump feeds four blending cells, it is critical that the water pressure to any one of them remains constant, regardless of how many cells are activated. The closed loop control is provided by a PID controller. This is included
in the VSD software, which is inserted within the control loop so that the loop can be tuned to ensure stable and accurate control with good response times. PID control is used to control a range of parameters such as flow and pressure. The PID controller then determines the optimum speed at which the pump’s motor achieves the correct water flow rate. A pressure transducer in the water tank feeds a signal to the VSD; and
as the pressure of the water varies, the pump’s speed is adjusted accordingly. This provides a constant flow of water into the system, ensuring the fruit juices are mixed to the right consistency every time. Of additional benefit, the VSD’s intuitive control keypad offers Framptons
more intelligence on the process. The keypad allows the user to customise the display to show key parameters such as water pressure, flow rate and energy savings in money, kWh or CO2
to 21 selected parameters, which can be displayed in various formats. ABB
