WebHeat energy in vacuum drying Using the same material as in Example 7.1, if vacuum drying is to be carried out at 60oC under the corresponding saturation pressure of 20kPa abs. (or a vacuum of 81.4 kPa), calculate the heat energy required to remove the moisture per unit weight of raw material. Heat energy required per kg raw material ... WebThe speed of the freeze-dry process depends on the sublimation of ice and the diffusion rate of vapor, the former indicator is also determined by the intensity of heat transfer to the sublimation interface, hence, the drying process is controlled by tow mechanisms.
