The TSMEE is an experimental device developed to study melting and mixing in twin rotor mixers during the Polymer Mixing Study conducted at the Polymer Processing Institute (95). 

Downstream from the mixing element section there are two separate inverse SSEs (see Section 6.2) that have the helical channel machined into the barrel, thus needing only rotating shafts to convey the material. Two pressure transducers, one diameter apart, record the pressure built up at closed discharge, a parameter that can be used to measure the viscosity of the molten blend at various shear rates. This rheometry section is the forerunner of the Helical Barrel Rheometer (HBR) of the Polymer Processing Institute (118). 

This industrially cosponsored program was carried out through the 1990s at the Polymer Processing Institute at New Jersey Institute of Technology, Hoboken, NJ, and directed by one of the authors.

The last section of both the M-M and DME modes consists of two separate HBRs. The mixing element sequences are a design variable.

For example, the performance of several mixing elements were evaluated and compared at the Polymer Processing Institute by using the TSMEE (twin-screw mixing elements evaluator) [34]. 

The Polymer Mixing Study carried out in Polymer Processing Institute selected typical semi-crystalline polymers and amorphous polymer. Figure 5.59 shows the energy required to reach the transition temperature for the polymers selected.
