A new spouted-bed configuration (rectangular cross-section with air entry through two bottom slots) was investigated as a dryer of milk and a paste mixture of milk and blackberry pulp. The aim was to analyze hydrodynamic stability and the effects of operating conditions on powder production efficiency. For the best conditions of paste-feeding flow rate, air temperature and inert type, hydrodynamic was stable and powder production efficiency was greater than 75%. The slot-rectangular spouted bed allowed for tripling of the paste-feeding flow rate at a lower air velocity compared to the conventional geometry, showing its potential for process scale-up
