A system for continuously processing a combination of materials, the system comprising: an acoustic agitator capable of being removably coupled to a process vessel; a continuous process vessel comprising: a first inlet configured for introducing at least one process ingredient; a plurality of plates configured for directing a flow of the at least one process ingredient downward through the continuous process vessel and capable of transferring acoustic energy generated by the acoustic agitator into the at least one process ingredient; an outlet for discharging a product of the at least one process ingredient subsequent to the at least one process ingredient passing through at least a portion of the continuous process vessel while being exposed to the acoustic energy transferred by at least one of the plurality of plates; and a fastener for removably coupling the continuous process vessel to the acoustic agitator; wherein the acoustic agitator is configured to oscillate the continuous process vessel such that the acoustic energy penetrates the entire contents of the continuous process vessel while the at least one process ingredient flows downward through the continuous process vessel via at least a gravitational force; and wherein the acoustic energy generated by the acoustic agitator has a frequency of less than 1 kHz. an acoustic agitator capable of being removably coupled to a process vessel; a continuous process vessel comprising: a first inlet configured for introducing at least one process ingredient; a plurality of plates configured for directing a flow of the at least one process ingredient downward through the continuous process vessel and capable of transferring acoustic energy generated by the acoustic agitator into the at least one process ingredient; an outlet for discharging a product of the at least one process ingredient subsequent to the at least one process ingredient passing through at least a portion of the continuous process vessel while being exposed to the acoustic energy transferred by at least one of the plurality of plates; and a first inlet configured for introducing at least one process ingredient; a plurality of plates configured for directing a flow of the at least one process ingredient downward through the continuous process vessel and capable of transferring acoustic energy generated by the acoustic agitator into the at least one process ingredient; an outlet for discharging a product of the at least one process ingredient subsequent to the at least one process ingredient passing through at least a portion of the continuous process vessel while being exposed to the acoustic energy transferred by at least one of the plurality of plates; and a fastener for removably coupling the continuous process vessel to the acoustic agitator; wherein the acoustic agitator is configured to oscillate the continuous process vessel such that the acoustic energy penetrates the entire contents of the continuous process vessel while the at least one process ingredient flows downward through the continuous process vessel via at least a gravitational force; and wherein the acoustic energy generated by the acoustic agitator has a frequency of less than 1 kHz.
