Sherwood Scientific Model 501 programmable fluid bed dryer

Sherwood Scientific’s Model 501 programmable fluid bed dryer provides a convenient laboratory-scale method of rapid moisture reduction/removal at relatively low temperature. Multiple configurations and microprocessor control ensure complete flexibility for a wide range of applications.

The fluid bed dryer delivers a high air-flow rate, breaking up wet samples and ensuring vigorous mixing so that drying is not only fast but uniform, with no lumps or caking of the particles. Microprocessor control of the air flow, inlet air temperature and drying period and a temperature/humidity probe within the tub assembly, enable all stages of the drying process to be programmed, monitored and analysed.

Offering a maximum sample capacity of 5 kg, the Model 501 is compatible with both glass and stainless steel drying tubs of various volumes and with a range of inlet and outlet filters and other accessories. This versatility makes it possible to dry hundreds of different sample types as well as carry out mixing, granulation and other processes.

The speed of fluid bed drying compared with conventional methods leads to faster sample testing and, therefore, production runs using a new material batch can be instigated sooner.

High reproducibility of the drying process and excellent homogeneity of the finished samples make the Model 501 suitable for studies of material-drying behaviour, optimising and scale up of drying processes and preparation of small sample batches for subsequent material studies.
