<p>Design method for bar confluence rod for concentrates preparation device Abstract The invention relates to a design method for the bar confluence rod for the concentrates preparation device using low pressure and low boiling point. The bar confluence rod comprises providing a rod body; providing the bar confluence rod with an abutment surface 5 corresponding to the interior crow surface of the cover body; symmetrically arranging a first arcuate surface opposed invagination to the two side surfaces vertical to the abutment surface; arranging a second arcuate surface opposed invagination to the top surface parallel to the abutment surface; forming an overflow prevention 10 edge between the first and second arcuate surface. The first and second arcuate surfaces enlarge the interface between hot and cool so as to incarese 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 15 condensed water drop directly from dropping into the concentrates, such that the density of concentrates is reduced. 1103b 1103a Fig.</p> |
