Patent number: 11762403Abstract: An arrangement for monitoring an aseptic manufacturing process includes product condition sensors capable of making closely spaced measurements of a product condition such as temperature or humidity. The measurements are made using closely spaced sensors arranged in a linear array on a single probe, which may be used to take measurements at multiple levels within the product. Data from the sensors is transmitted to a data collection point via short range wireless digital communications. The sensors may be used to measure temperature and humidity at a single point. For example, when the sensors are used in pharmaceutical freeze drying, the location of a sublimation front may be calculated for each vial, and the freeze drying process may be controlled using the data.Type: GrantFiled: January 31, 2023Date of Patent: September 19, 2023Assignee: IMA LIFE NORTH AMERICA INC.Inventors: Joseph Brower, Arnab Ganguly, Ernesto Renzi, Francis W. Demarco, Michele Arduini

Publication number: 20230235956Abstract: A compact freeze dryer removes a liquid from a bulk powder product. The freeze dryer utilizes a single cryogenic vessel for both (1) freezing the liquid contained in the bulk product, and (2) condensing vapor resulting from sublimating the frozen liquid. A vacuum pump is connected to the cryogenic vessel for drawing a vacuum in the cryogenic vessel and in a drying vessel. Vapor resulting from subliming the frozen liquid in the drying vessel is drawn into the cryogenic vessel and condensed.Type: ApplicationFiled: May 24, 2021Publication date: July 27, 2023Inventors: David Debo, Arnab Ganguly, Dennis Posheluk, Ernesto Renzi

Patent number: 11448463Abstract: 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).Type: GrantFiled: October 1, 2019Date of Patent: September 20, 2022Assignee: IMA Life North America Inc.Inventors: Arnab Ganguly, Francis W.

Patent number: 11359861Abstract: 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.Type: GrantFiled: April 9, 2019Date of Patent: June 14, 2022Assignee: IMA LIFE NORTH AMERICA INC.Inventors: Arnab Ganguly, Ernesto Renzi, Francis W.

Publication number: 20210381766Abstract: A freeze drying system (200) having a nozzle (30) operated at a setpoint pressure to generate fluid product drops (242) for freezing in a freezing chamber (244) of a freezing vessel (228). The freezing chamber includes an inner wall (250) that defines a cavity (254) and an outer wall (252) having an inlet (260) that extends from a location on the outer wall that is lower than an outlet (262). A cooling fluid flows through the inlet, cavity and outlet to form a freezing zone (280). A drying chamber (304) having sloped shelves (352) receives frozen particles (282) from the freezing chamber. A heating element (418) is associated with each shelf that heats the frozen particles to promote sublimation. Vibration elements (396, 398, 400, 402) located outside the drying chamber vibrate the shelves causing the frozen particles to move from shelf to shelf to form freeze dried product (284).Type: ApplicationFiled: October 11, 2018Publication date: December 9, 2021Inventors: ARNAB GANGULY, FRANCIS W.

Publication number: 20210190425Abstract: A freeze dryer processes a bulk material including a liquid, and produces a product including the freeze dried material borne on a substrate. The material is introduced in a freezing chamber as a droplet stream that impinges on the substrate. The liquid in the material is frozen after it contacts the substrate. The substrate bearing the material is transferred through a vacuum lock into a vacuum drying chamber where the frozen liquid sublimates under vacuum and applied heat.Type: ApplicationFiled: November 22, 2017Publication date: June 24, 2021Inventors: ARNAB GANGULY, FRANCIS W.
