How is vacuum drying used to treat heat stress?


How is vacuum drying used to treat heat stress?

The use of controlled low temperature vacuum drying (CLTVD) which operates at pressures just above the triple point of water and a product temperature close to 0°C minimizes exposure of the cells to heat stress.See all results for this questionsp.info Which is better MVD or air drier for vacuum drying?The combination of MVD and AD is perhaps the most obvious option: as AD is relatively cheap, the first part of the process is preferably an air-drier. During the constant rate period, the drying rate is acceptable and the product remains cool due to the cooling effect of the evaporation.See all results for this questionsp.info How Choose Vacuum Dryer - Chemical ProcessingA vacuum dryer's upper temperature limit (typically about 600° F) is lower than that of a direct-heat dryer.
