Claim:
1. A liquid asphalt heating and mixing system for a liquid asphalt storage vessel of an asphalt production plant, said heating and mixing system comprising: a heat exchanger positioned within said liquid asphalt storage vessel of an asphalt production plant; a fluid heater and circulator connected to said heat exchanger for circulating heated fluid through said heat exchanger for heating said liquid asphalt within said storage vessel; an eductor mixer centrally positioned longitudinally in said heat exchanger, said eductor mixer having an intake end and a discharge end wherein said intake end is positioned within said heat exchanger and said discharge end is directed outwardly from said heat exchanger; a liquid asphalt pump connected to said eductor mixer and to said storage vessel to pump liquid asphalt from said storage vessel back to said eductor mixer; whereby said liquid asphalt pumped through said eductor mixer induces liquid asphalt within said storage vessel to flow around said heat exchanger which transfers heat from the circulating heated fluid therein to the liquid asphalt as it is drawn into said intake end of the eductor mixer and discharged through said discharge end of the eductor mixer for mixing the liquid asphalt within the storage vessel.
