Swenson has tested more than 700 different products over the past forty years. In addition to crystallization and evaporation testing equipment, the test center maintains a variety of dryers exclusively for testing purposes. The rotary dryer is operable in either the parallel current or countercurrent mode. Test results reveal important product drying characteristics, summarized in terms of particle size, moisture content, flowability, solubility, color and operating parameters. Tests are conducted so that the laboratory process will duplicate the commercial process as closely as possible for customer evaluation.
Custom drying of material is possible on a limited scale.
