Abstract

The beans are suspended in a hot, fluidised bed or fine, solid particles of a chemically inert nature and thickness 30 times the average mesh size of the beans. The average density of the bed particles is 1.2 to 4.0 times the initial density of the beans. The particles are heated and transfer heat to the beans by contact. Roasted beans are skimmed off the top and discharged from the roasting chamber. Beans are pref. fed continuously through the fluidised bed. The injection speed of recyclable fluidising gas into the bed is pref. about 3 times the min. necessary to fluidise the fine particles. The mesh size of the fine particles is pref. less than 1/2 of that of the beans. The total wt. of beans should be 25% of the wt. of fine particles. After discharge from the roasting chamber the prod. is pref. sepd. from the fine particles on a vibrating screen through which cold air is blown to cool the prod. It is now possible to roast the beans continuously and the prod. receives homogeneous treatment with no local overheating or scaling. Thermal efficiency is raised by bombarding the beans with hot particles.
