Continuous Drum Dryer: Our novel continuous dryer converts concentrated or diluted suspensions containing the API into a dry, flowable powder in just a few minutes. The suspension is deposited onto two heated rotating drums, forming thin layers that are quickly dried. The entire system is under vacuum, allowing the process material to be maintained at lower temperatures. The dried API is then conveyed to the next unit operation. In-line PATs allow for real-time measurement of particle size, residual solvent, and crystal form.
