    摘要: A freeze dryer processes bulk powder products. The freeze dryer freezes the product by mixing an atomized spray of product with sterile liquid nitrogen. The resultant powder is freeze dried in a vessel, and the vessel contents is agitated to maintain product contact with heated vessel wall and to prevent agglomeration.

    摘要: A freeze drying vessel (302) having a freeze drying chamber (304) that includes sloped horizontal shelves (352) that receive frozen particles (282). Each shelf is sloped relative to a horizontal axis (390) and arranged such that a downward slope between successive shelves alternates between first (392) and second (394) directions. At least one connecting member (374, 376, 378, 380, 382, 384, 386, 386, 388) is attached between pairs of shelves. At least one connecting member is attached to an associated vibration element (396, 398, 400, 402) located outside the drying chamber. Each vibration element vibrates a pair of shelves to cause the frozen particles to advance relative to an associated shelf and drop downward from shelf to shelf wherein the shelves heat the frozen particles to promote sublimation to form freeze dried product (284).

    摘要: In a system and method for controlling a freeze drying process, a diagnostics server (718) is connected for receiving time series data from a freeze drying system (710, 711). The diagnostics server uses a tuned freeze drying system mathematical model to analyze the time series data to predict a system event, and alter the freeze drying process. An analytics server (730) is connected for secure communication with the diagnostics server, and creates and tunes the freeze drying system mathematical model. An equipment provider service and diagnostic cloud (735) may apply learning algorithms to the time series data to enhance diagnostic tools and provide predictive maintenance and diagnostic services to the operator of the first production sites using the diagnostic tools.
