4. a frozen cream ice is placed into the container before the freezing process is complete. The container has a slinder-shaped dimension with a diameter of 3.5m and is then placed in a water blast freezer with a heat conductivity coefficient of -25 W (m2 k). product temperature of -11 c and air temperature of -25 c. product density is 700kg / m3. thermal conductivity (frozen) 1.2 W / (m K), and specific heat 1.9 kj (kg / K). if latent heat is lost during the blast freezing process 250k j / kg. make an estimated freezing time? ... (kj / w)
