These thesis presents the development of pushing out medias with ice slurry and its preparation. Ice slurry sistems are nowadays used in industry, but mainly for cooling purposes. With ice slurry we can efficiently push out media and clean up tube. In addition, we save on water, throwing away product and reducing the use of CIP cleaners. Also we contribute to reduce pollution of the environment and increase the profitability of production. The procedures for the preparation of ice slurry and design of the test track, measurement of the viscosity of products, push outs of products with ice slurry, measurement of pressure drops and results of measurements are presented in this thesis.
