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.
Claims21
A process for electrostatic spray drying of a living microorganism, the process comprising:
- applying an electrostatic charge to a suspension comprising a live microorganism, a solvent, and an additive, wherein the suspension comprises at least 35% by weight water;
- forming droplets of said suspension;
- drying said droplets, thereby forming dried particles;
- and
- collecting the dried particles;
- wherein the solvent has a higher dielectric constant than the additive, and the additive has a higher dielectric constant than the microorganism.
