An apparatus, system, and method of irradiating fluent food products. The present invention utilizes a transmissive wall having a convex surface. A source of radiation is positioned on a side of the transmissive wall that is opposite the convex surface so that when the radiation source is emitting radiation energy, the radiation energy passes through the transmissive wall, thereby irradiating fluent food product that is flowing in contact with the convex surface.一種放射流質食品之設備、系統與方法。本發明利用具有一凸表面之傳遞壁。一放射源位於對面於凸表面之該傳遞壁一側上,使得當放射源射出放射能量時,該放射能量穿過傳遞壁,藉以放射與該凸表面接觸流過之流質食品。10...源15...供應管路20...放射腔21...第一壁22...第二壁25...出口管路29...產品流量腔30...輻射源31...放射能量40...控制閥50...真空泵60...封裝器70...CPU80...輻射感測器90...使用者界面100...放射系統110...外殼
