The invention relates to a bar confluence rod for the concentrates preparation device using low pressure and low boiling point. The bar confluence rod comprises a rod body; the bar confluence rod is provided with an abutment surface corresponding to the interior crow surface of thecover body, a first arcuate surface opposed invagination is symmetrically arranged to the two side surfaces vertical to the abutment surface, a second arcuate surface opposed invagination is arranged to the top surface parallel to the abutment surface, an overflow prevention edge is formed between the first and second arcuate surface. The first and second arcuate surfaces enlarge the interface between hot and cool so as to increase the condensing efficiency. The overflow prevention edge makes condensed water drop slide along the first and second arcuate surfaces into the confluence chamber so as to prevent condensed water drop directly from dropping into the concentrates, such that the density of concentrates is reduced. <Figure 3> |
