Abstract:
Method for transfer of containers, such as vials (101), between a freeze dryer (1) that is located at a first location and a separate transport vehicle (30) that is mobile with respect to the freeze dryer, wherein the freeze dryer (1) comprises a freeze dryer housing (2) with an access opening (11) towards an inner freeze drying chamber (10) inside the freeze dryer housing (2), multiple shelves (21-24) that are arranged spaced apart above each other inside the freeze dryer chamber (10) and each provided with a horizontally extending first flat supporting surface (25) for supporting the containers, wherein the mobile transport vehicle (30) comprises a mobile undercarriage (31) supporting a storage housing (33) with an access opening (40) towards an inner storage chamber (39), a carrier provided with a second flat supporting surface (58) for supporting the containers inside the storage housing (33), and a container shifter (60) for pushing out containers away from the second flat supporting surface (58) in a pushing out direction parallel to the second flat supporting surface (58).
Abstract:
The disclosure provides for a system and method of characterizing or inspecting the content of moving containers with Infrared IR spectroscopy from the side. Data processing techniques are used to eliminate effects of variable path lengths and light scattering in such way that the resulting spectra are comparable with a spectra acquired from static containers.
Abstract:
The feeder module comprises a number, for instance five to eight, feeder units. Each feeder unit includes a storage hopper, a weighing cell, a conveyer, and a discharge end. The feeder units may be arranged in a single level and in a spokes-like configuration,in which each feeder unit extends radially outwards from an imaginary inner circle defined at the discharge end adapted to face the common receiving container to an imaginary outer circle defined by radially opposite end of each feeder unit, the feeder units being positioned substantially on radii extending from the inner circle. The feeder module makes it possible to provide a very accurately dosed mixture of one or more powders to a receiving container.
Abstract:
A feeder unit (2) comprising a storage hopper (21), a weighing cell (24), a conveyer (22), and a discharge end (23), wherein the storage hopper is adapted to be connected to a refilling system, and the discharge end (23) to a receiving container. A working space (ws) is defined by the aritmethic product of the dead weight (dw) of the feeder unit (2) and the refilling interval (ri), such that the working space (ws) is below 0.2 kgh. Furthermore a method method for discharging a constant mass flow of one or more powders into a receiving container is defined.

Abstract:
Device for treatment of materials by freeze drying, comprising a housing (2) having first walls (9,15) that define a drying chamber (3) that is equipped for the accommodation of the material for drying and destined for carrying out the freeze drying process, and a controller assembly (40) for the evaluation of process parameters during the freeze drying process, wherein the controller assembly comprises a controller antenna (41) for high frequency electromagnetic wireless communication with measuring transponders (23) arranged within the drying chamber (3), which controller antenna (41) is placed outside the drying chamber (3).
Abstract:
A method of determining the mass of a moving sample is described, in which the sample is moved at a controlled velocity through a mass interrogation zone and a temperature interrogation zone, which may be upstream or downstream from the mass interrogation zone. Using a magnetic resonance method, a first signal is generated as the sample passes through the mass interrogation zone, the first signal having a characteristic that varies with the mass of the sample and with the temperature of the sample. A beam of electromagnetic radiation of a terahertz frequency or a near-infrared wavelength is generated and directed through the temperature interrogation zone. As the sample moves through the temperature interrogation zone, the electromagnetic radiation reflected from or transmitted through the sample is detected, and from that detected electromagnetic radiation a second signal is generated that has a characteristic that varies with the temperature of the sample. The characteristic of the first signal is adjusted using the second signal to produce a temperature compensated characteristic, which is compared to a similar characteristic obtained from a similar sample of known mass to determine the mass of the sample.
