Abstract: The present invention provides a process for spray freezing or spray freeze drying under conditions of very low oxygen pressure, such as under essentially anaerobic conditions, and particularly a process for spray freezing strict anaerobic microorganisms (bacteria) under conditions where the level of oxygen is very low, or essentially anaerobic. Further, the invention provides a product achievable by the processes and an apparatus usable in the process.

Abstract: The present disclosure relates to a process for electrostatic spray drying of a living microorganism, the process comprising the following steps: a. Providing a suspension, comprising a number of components, including a microorganism, a solvent and an additive; b. Applying an electrostatic charge to said suspension; c. Forming droplets of said suspension; d. Drying said droplets, thereby forming dried particles; and e. (Optionally) collecting the dried particles.

Abstract: The invention relates to a plant for production of tablets, a process for production of tablets and tablets as such. The plant comprises a mixing device producing a mixed liquid feed of active pharmaceutical ingredient and excipients. A spray dryer atomizes the mixed liquid feed and dried particles with a high flowability are produced. The dried particles are subsequently compressed to tablets in a tablet press. The invention possesses several advantages, including the possibility of using an auto mated rotary tablet press directly, thereby reducing the number of unit operations in the tablet production.
