Abstract: A container conveying system including a controller, a first robot, and/or a second robot. A first container pickup mechanism is provided on the first robot. A second container pickup mechanism is provided on the second robot. The controller is configured to, in response to a container conveying request, send a first conveying instruction to the first robot if it is determined a target container to be conveyed based on the container conveying request has a size within a first size range; or send a second conveying instruction to the second robot if it is determined the target has a size within a second size range. In warehousing operation scenarios, by jointly using the two robots for operation, containers with various container sizes can be picked up and placed, thus improving utilization rate of a container storage space.

Abstract: A method of monitoring and controlling a freeze drying process in a freeze drying apparatus having walls, shelves and a number of vials or trays positioned on different areas of the shelves and containing product to be freeze dried. One or more vials or trays are selected that are representative of the positions of all of the vials or trays in different areas of the shelves. One or more heat flux sensors are positioned between the selected vials or trays and adjacent portions of the walls and/or shelves. The heat transfer between the selected vials or trays and the adjacent wall or shelf portions is measured during the freezing and drying stages of the freeze drying process.
