We have been dealing with the bench-top spray drying of a hydroalcoholic herbal extract comprising around 30 GL ethanolic content and 5% solid content. The evaporatory capacity is 1.0 L/h and the equipment is operated in concurrent flow regime. The pneumatic (two-fluid) spray noozle available has 1.0 mm or 1.2 mm inner diameter. The nozzle air pressure is 0.4 MPa. The drying air is supplied by a blower (nominal flow rate of 1.0 m3/min) and electrically heated. The cylindrical drying chamber was made of borosilicate glass with 160 mm in diameter and 645 mm in height. Is it possible to determine which could be the safer experimental condiitons (i.e., range of drying air inlet temperature, extract feed rate, spraying air flow-rate, etc.)? Do you guys reccomend any literature regarding this issue?
