Abstract: Apparatus for selectively dispensing liquid phase cryogen from a two phase cryogenic fluid, and process therefor, comprising: 1. AT LEAST ONE LIQUID SPRAY NOZZLE FOR DIRECTING A SPRAY OF LIQUID CRYOGEN UPON THE PRODUCTS TO BE REFRIGERATED, 2. AT LEAST ONE VAPOR VENTING NOZZLE FOR DIRECTING SUBSTANTIALLY ALL OF THE VAPOR PHASE CRYOGEN INTO THE SURROUNDING ATMOSPHERE, AND 3. MANIFOLD MEANS CONNECTED TO A SOURCE OF CRYOGENIC FLUID FOR CONVEYING SAID CRYOGENIC FLUID TO THE LIQUID AND VAPOR NOZZLES. The respective inlet ports of the liquid spray nozzle and the vapor venting nozzle are located in the lower and upper sections, respectively, of the manifold means. The equivalent cross-sectional area of the discharge orifice of the vapor venting nozzle is from about 1/3-2/3 of the corresponding area of the discharge orifice of the liquid spray nozzle.
