  • Patent number: 7329430
    Abstract: The present invention relates to a method for coating of a pharmaceutical product. The method comprises the step of producing discrete droplets (7) of controlled size, shape and composition with at least one micro dispenser (1) and distributing droplets (7) with controlled velocity, time of flight. Also, the method comprises the step of controlling the production frequency and modulation of the droplets (7). Further, the method comprises the step of controlling the flow rate, temperature and composition of the carrier gas and directing droplets (7) towards particles (10) subjected to coating. The present invention also relates to a device for coating of a pharmaceutical product. The device comprises a droplet producing unit (1) and a droplet-directing unit (8). The droplet producing unit (1) is a piezo-actuated micro dispenser (1) for producing discrete droplets (7) and controlling the size, shape and composition of said droplets (7).

  • Patent number: 7213474
    Abstract: An apparatus for use in sampling material on-line in a process system, comprising a sample collector (1) for receiving a sample of material, an elongate shaft (10) defining a passageway (14) carrying a measurement probe (11) for taking measurements from a colelcted sample, a pressurised fluid supply (31) connected to the passageway for delivering a pressurised fluid through the passageway to the sample collector for displacing the collected sample and a nozzle (33) provided at the distal end of the measurement probe (11) for distributing the pressurised fluid to the sample collector for displacing the collected sample from the sample collector (1).

  • Patent number: 6946157
    Abstract: In a method of monitoring the formation of a coating on a single particle (P), an apparatus is used which comprises means (2,5,6,9) for arranging said particle (P) at a given spatial location, and a fluid supply unit (3) adapted to apply a coating fluid to the particle (P) such that the coating is formed. Further, the apparatus has a measurement unit (4) which is adapted to perform a spectrometric measurement on the coating during formation thereof, and to derive a measurement value of at least one principle parameter related to the coating. This, such principle parameters, for example the thickness, thickness growth rate and physical and/or chemical properties related to the quality of the coating, as well as heat, mass and momentum transfer, can be continuously and non-invasively monitored during the coating process on the single particle (P).

  • Patent number: 6633792
    Abstract: This invention relates to a method for controlling the process of manufacturing a coating of a pharmaceutical product, comprising the steps of: performing a spectroscopic measurement on the coating; generating a sample vector of measurement values from the spectrometric measurement; condensing the measurement values into at least one principal parameter; comparing the principal parameter to a predetermined corresponding model parameter; determining deviations of the principal parameter from the corresponding model parameter and extracting information directly related to the quality of the coating; and controlling the process on the basis, at least partly, of the extracted information.
