Abstract

A preparation vessel, in particular for a food processor, has a vessel wall and a preparation area surrounded by the vessel wall. The vessel wall has a cooling device that contacts the vessel wall in a heat-conducting manner for cooling a preparation item present in the preparation area. The vessel wall in at least a partial area has a double-walled design, with an inner wall bordering the preparation area and an outer wall that is formed separately from the inner wall and spaced apart from the inner wall by a gap, wherein the gap has the cooling device and a phase change material located between the cooling device and the outer wall as viewed in a direction from the preparation area to the outer wall.
