Abstract: A factory scale process for producing crystalline atorvastatin calcium includes the step of drying the isolated product in a vacuum pan dryer. The vacuum pan dryer has an agitator which is continuously rotated at a speed of approximately 1 rpm. High quality material is routinely and consistently produced with reduced cycle time.

Abstract: A unit 1 for producing pyrogen controlled water on a small to medium factory scale comprises a number of charged ultrafiltration units 10 arranged in parallel. Orifice plates 15 are used to restrict and control the flow of deionized water to each filter 10. The filter units 10 are mounted on a frame 2 with a wheeled chassis 3 which may be pushed or moved by a forklift truck to a site where pyrogen controlled water is required. The unit 1 has an inlet line 4 for connection to a supply of deionized water and an outlet line 6 for connection to a user of pyrogen controlled water. The unit 1 may be purged with nitrogen from a supply 18. Sampling ports 17 in a common supply inlet 4 and a common outlet 6 ensure that the filtration efficiency can be closely monitored. The flow of water is monitored by a flowmeter 19 and pressure sensors 16 upstream of each filter facilitate a high level of control.
