Abstract:
1. A method for RF dielectric heating an object immersed in a medium; said method comprising: (A) placing said object and medium into an enclosure; wherein said object substantially has absorbed said medium in a first “cool” state; and wherein said object includes a maximum weight in said first “cool” state due to absorption of said medium; (B) adding an ionic substance to at least one of said object and medium; (C) initiating a heating process by subjecting said object and medium to a variable AC electrical field produced by an RF source; wherein said object is substantially free from said medium in a second “heated” state due to substantial release of said medium from said object; and said released medium is substantially evaporated during said heating process; and (D) controlling said heating process, wherein said heating process is terminated when said object is substantially transitioned into said second “heated” state; wherein said ionic substance is a substance from the group consisting of a dilute acidic substance of mineral acid; and hydrochloric acid.
