Thermal exchange food processing device and method of producing same

A thermal exchange food processing device for processing at least one target foodstuff, comprising:

• a thermal conductive body comprising an acting region adapted for being in contact with and exchanging heat with the at least one target foodstuff and at least one inner thermal conductive region disposed corresponding to, and in thermal connection with, the acting region;
• a thermal insulation layer having a lower thermal conductivity coefficient than the thermal conductive body and encapsulating at least a portion of the thermal conductive body, so that the acting region of the thermal conductive body is exposed while remaining regions of the thermal conductive body other than the acting region are thermally insulated from the ambient environment, wherein the thermal conductive body alone or together with the thermal insulation layer defines an accommodation space and the inner thermal conductive region is disposed to face the accommodation space;
• and
• a phase change material disposed within the accommodation space and in thermal connection to the inner thermal conductive region;
• wherein the thermal conductive body further comprises:
• a processing portion comprising two side surfaces covered completely by the thermal insulation layer, wherein the acting region is a side edge connected to the two side surfaces;
• and
• a hollow handle portion extending from the processing portion and formed with the accommodation space.
