A popcorn making machine for the continuous popping of corn kernels, including a main unit, said main unit comprising: a fan; a heating chamber communicated with said fan; a heater means for heating air mounted within said heating chamber; a feeding means for supplying raw corn kernels into a heating bowl at a predetermined rate; said heating bowl being disposed within said heating chamber, said bowl including: sidewalls tapered downwardly, a bottom opening, and a plurality of predeterminedly configured mini-nozzles internally attached to said sidewalls; wherein each said mini-nozzle covers an orifice made in the sidewall so that hot airflows can be introduced from said heating chamber through said orifices and said mini-nozzles into the interior of said bowl toward directions, essentially tangential to the inner surface of said bowl, and collectively forming a main hot airflow circulation within said bowl; and a central nozzle having: a convex shape with a bottom flat opening, peripherally coupled to said bottom opening of the bowl, and a plurality of equidistantly situated and predeterminedly configured slots, such that additional hot airflows can be introduced from said heating chamber through said slots into said bowl; wherein said additional hot airflows are directed essentially tangential to the outer surface of said central nozzle, thereby collectively forming an additional hot airflow circulation surrounding said central nozzle, and said additional circulation is oriented essentially toward the direction of said main circulation. a fan; a heating chamber communicated with said fan; a heater means for heating air mounted within said heating chamber; a feeding means for supplying raw corn kernels into a heating bowl at a predetermined rate; said heating bowl being disposed within said heating chamber, said bowl including: sidewalls tapered downwardly, a bottom opening, and a plurality of predeterminedly configured mini-nozzles internally attached to said sidewalls; wherein each said mini-nozzle covers an orifice made in the sidewall so that hot airflows can be introduced from said heating chamber through said orifices and said mini-nozzles into the interior of said bowl toward directions, essentially tangential to the inner surface of said bowl, and collectively forming a main hot airflow circulation within said bowl; and sidewalls tapered downwardly, a bottom opening, and a plurality of predeterminedly configured mini-nozzles internally attached to said sidewalls; wherein each said mini-nozzle covers an orifice made in the sidewall so that hot airflows can be introduced from said heating chamber through said orifices and said mini-nozzles into the interior of said bowl toward directions, essentially tangential to the inner surface of said bowl, and collectively forming a main hot airflow circulation within said bowl; and a central nozzle having: a convex shape with a bottom flat opening, peripherally coupled to said bottom opening of the bowl, and a plurality of equidistantly situated and predeterminedly configured slots, such that additional hot airflows can be introduced from said heating chamber through said slots into said bowl; wherein said additional hot airflows are directed essentially tangential to the outer surface of said central nozzle, thereby collectively forming an additional hot airflow circulation surrounding said central nozzle, and said additional circulation is oriented essentially toward the direction of said main circulation. a convex shape with a bottom flat opening, peripherally coupled to said bottom opening of the bowl, and a plurality of equidistantly situated and predeterminedly configured slots, such that additional hot airflows can be introduced from said heating chamber through said slots into said bowl; wherein said additional hot airflows are directed essentially tangential to the outer surface of said central nozzle, thereby collectively forming an additional hot airflow circulation surrounding said central nozzle, and said additional circulation is oriented essentially toward the direction of said main circulation.
