    • Several components relating to a heating apparatus which preferably are used in conjunction with each other in an apparatus for heating solid granular or particulate material, such as aggregate used to make asphalt concrete. One component of the present invention includes a heater-condenser unit (32) which indirectly heats the material by circulating heat transfer fluid within hollow plates (24) contained in a housing (232) holding the material. The heat transfer fluid used in the heater-condenser (32) preferably is supplied in the form of a vapor or gas involved from liquid contained in material heated by another type of heater (38). In this other type of heater (38), the material to be dried enters a chamber (106) containing hollow heat exchange plates (180) through which a primary heat transfer liquid is circulating.
    • 与用于加热固体颗粒或颗粒材料的装置(例如用于制备沥青混凝土的聚集体)相关联的加热装置的几个部件优选地彼此结合使用。 本发明的一个部件包括加热器 - 冷凝器单元(32),该加热器 - 冷凝器单元通过将容纳在保持该材料的壳体(232)中的中空板(24)内的传热流体循环来间接加热该材料。 在加热器 - 冷凝器(32)中使用的传热流体优选地以与包含在由另一种加热器(38)加热的材料中的液体相关的蒸汽或气体的形式供应。 在这种其他类型的加热器(38)中,要干燥的材料进入包含中空热交换板(180)的腔室(106),一次传热液体通过该空间换热板循环。
