    • The invention relates to a process and apparatus to agglomerate soluble coffee particles. The process comprises feeding a curtain of soluble coffee particles to an agglomerator. The curtain falls between a pair of steam distributors (66, 68) which spray steam which intersects the particles causing wetting and fusion of coffee particles to form agglomerates. The moist agglomerates pass through a tempering zone where they are partially surface dried by a draft of laminar air of a temperature less than 200°F (93.3°C) which moves downward with the agglomerates. The agglomerates are collected on a moving continuous belt (48), transferred to a drier and are subsequently dried to a moisture content of 5% or less. A process is also disclosed for darkening a light-colour, granular soluble coffee product.
    • 本发明涉及一种使可溶性咖啡颗粒附聚的方法和装置。 该方法包括将可溶性咖啡颗粒的帘幕进料到附聚器。 窗帘落在一对蒸汽分配器(66,68)之间,蒸汽分配器(66,68)喷射与颗粒相交的蒸汽,导致咖啡颗粒的润湿和熔融以形成附聚物。 潮湿的团块通过回火区域,通过回火区域,其部分表面干燥,其中温度小于200°F(93.3℃)的层流空气通过附聚物向下移动。 将附聚物收集在移动的连续带(48)上,转移到干燥器中,随后干燥至5%或更低的含水量。 还公开了一种使浅色颗粒状可溶性咖啡产品变暗的方法。
