ABSTRACT:
An evaporator includes a maple sap evaporating pan in fluid communication with a maple syrup forming pan, a fire box in gas communication with gas circulating adjuncts, a flue stack and chimney and an auxiliary reservoir for pre-heating the sap prior to entering the maple sap evaporating pan. The auxiliary reservoir consists of a housing defined in the flue stack with an inlet for receiving cold sap. A series of horizontally spaced open end vertical tubes extends through the housing, each tube including a lower inlet receiving from the adjuncts flue gases that circulate through and heat the tubes and an upper outlet allowing the gases to exit through the chimney. Hence, cold sap received in the auxiliary reservoir is first heated by contact with the hot tubes.
