Influences of Temperature of Vapour-Condenser and Pressure in the Vacuum Chamber on the Cooling Rate during Vacuum Cooling [PDF]
The temperature of vapour-condenser below 0°C and the final pressure in the vacuum chamber below 0.61kPa during vacuum cooling were experimentally analysed in this paper. The temperature of vapour-condenser, -2°C, -35°C, -39°C and -71°C, and the final pressure in the vacuum chamber, 0.3kPa, 0.4kPa, 0.5kPa and 0.61kPa, were chosen.

Study of Methods to Reduce Water Loss Rate for Vegetables in Vacuum Cooling
Water loss is inevitable during vacuum cooling because the temperature is decreased through the loss of water in vegetables. The cooling effect of leafy vegetables in vacuum cooling is evident, but that of root vegetables is not obvious because their ...
