Page 8: Chapter 1: Introducing The Starch Pasting Cell (Spc)
Chapter 1: Introducing the Starch Pasting Cell (SPC) Overview This manual is intended as an addendum to the DHR and AR-G2/AR 2000ex/AR 1500ex Rheometer Getting Started Guides. The Smart Swap™ Starch Pasting Cell (SPC) is designed to measure the viscosity of starch using methods currently in use in the starch industry. -
Page 9: System Components
System Components The SPC consists of four components: • The jacket, which is mounted on the instrument base • The cup, which is removable and inserts into the jacket • The cap, which screws onto the jacket to hold the cup in place •... -
Page 10: Temperature Control
Temperature Control Heating is accomplished through the electrical elements placed within the jacket, concentrically to the cup. The sample is cooled using water carried in a helical conduit in close proximity to the cup outer walls. The cooling water flow is controlled through the Cooling Control Unit (CCU), which is placed upstream of the cup. -

Page 14: Connecting The Cooling Control Unit (Ccu)
Connecting the Cooling Control Unit (CCU) The flow of the cooling water and purge air is controlled through a CCU, shown below. This unit may be free standing, or wall mounted using the clearance holes on top of the unit. Figure 8 Cooling Control Unit (CCU). -
Page 15: Setting The Cooling Water Parameters
Connect the GAS/LIQUID outlet port to the upper port on the Starch Cell jacket, using the 4-mm outer diameter tubing with the 4-mm to 6-mm adapter provided. Using the 4-mm outer diameter tubing connect the lower port on the Starch Cell jacket to the drain, if the mains water is the supply, or to the return, if a fluid circulator is used. -
Page 16: Chapter 3: Spc Use And Maintenance
Chapter 3: SPC Use and Maintenance Running an SPC Procedure Perform the following steps to load your sample, run the experiment, then remove the sample: Raise the instrument head to the full back off distance. Remove the Starch Cell cap and cup from the jacket. See Chapter 3 for information, if needed. -
Page 17: Maintaining The Spc
See TRIOS software Online Help for details. Rotational Mapping Rotational mapping is used on the TA Instruments' AR Series Rheometers to ensure optimal performance for very sensitive samples. It should not normally be necessary with the Starch Cell, but may be used if very precise data are required at low angular velocities. -
