The normal vacuum range of a vacuum freeze dryer is typically between 10 Pa and 1000 Pa, with the specific value influenced by the material properties and processing technology. This vacuum range is beneficial for accelerating the sublimation rate and improving drying efficiency.
The vacuum level of a vacuum freeze dryer refers to the degree to which the internal gas pressure is lower than the external atmospheric pressure. This parameter is crucial for the normal operation of the equipment and the drying effect. However, there is no uniform and fixed value for the normal vacuum level of a freeze dryer, as it is affected by various factors, including the type, specifications, application, and operating conditions of the equipment.
