ABSTRACT:
A piggy back evaporator includes a drip pan having an oblique condensate drain sheet extending over the major length of the same. A steam hole within the condensate drain sheet allows steam to reach the lower surface of a bottom wall of a piggy back pan. The piggy back pan bottom wall is corrugated to define a series of laterally spaced troughs on its upper face and flues on its lower face. Maple sap is fed into the piggy back pan to a level covering the corrugations of the bottom wall. A hood overlies the piggy back pan and seals off the interior thereof. A high pressure air blower is mounted to the hood and feeds air under pressure into a plenum chamber and downwardly through the downpipes into individual horizontal sparging tubes which extend the length of the piggy back pan and are located within the bottoms of individual troughs defined by the corrugations. Air under pressure passes through pin holes within the sparging tubes with the bubbles formed thereby scouring the metal surfaces of the troughs within the piggy back bottom wall and additionally creating an effective frothing action for the sap within the piggy back pan. The air passing through the sap is effectively heated and saturated with moisture with the resulting evaporation of the moisture captured by the air consuming a large quantity of heat to maintain a temperature differential between the sap/air mixture and condensing steam under the pan such that almost all of the steam is condensed in the area between the drip pan and the piggy back pan to increase the liquid concentration of the sap being processed.
