摘要： A process is provided for freeze-drying an aqueous liquid product which comprises distributing the liquid product in containers closely fitted in cavities of a tray-shaped heat-conducting solid metal block having relatively high heat transfer, subjecting the block to accelerated cooling such that the liquid in each container is frozen thereby freezing the liquid in each container at substantially the same rate, and drying the frozen product under vacuum while in the block so that the frozen product in each container is dried at substantially the same rate.
