Özet
The moisture content changes under optimum drying conditions of a droplet of ?-amylase solution leaving the nozzle in a specially designed horizontal spray dryer was investigated. In a horizontal spray dryer of 6 × 3 × 3 m size, the gas entered at 155°C concurrently with the ?-amylase solution being sprayed from two pressure nozzles. The particles were collected in a channel through which they were transported to the cyclone pneumatically. The air rate was adjusted to keep the temperature below 60°C during the powder travel in the channel. During the operation, the activity loss of the powder was determined as 9%. The fully dry, equilibrium and critical moisture contents of the powder were determined by off-line experiments. These values were fed to the computer program to predict the final moisture content of particles. A good agreement between the predicted and the experimental values was found. © 1997 Elsevier Science Limited.
