Abstract: In this paper, various measures for intensifying the process of spray drying of vegetable tannin extract are discuessed, namely, increasing the feed stock concentration and temperature, speeding up the spinning disc atomisers, making the best choice of the conditions for atomization, improving the distribution of heated air, adjusting the particle size and particle-size distribution, controlling air temperature at the inlet and outlet, improving the recovery system of dust particles, etc. Through the intensification of heat and mass transfer, purposes of raising heat efficiency, increasing productive effect and improving product qualities can be achieved.
