Drying processes in Biotech are designed to:
- Increase the life-cycle of an active product by stabilizing it in dry form
- reduce the transport quantity
- provide a convenient delivery form as a solid tablet, a soluble product,
wettable solution, suspension liquid, inhalation, etc.
Typical products are: Bacterial soup, yeast cells, yeast
extract, yeast autolysate, l-lysine, proteins, etc.
often included in the drying process by surface agent migration during drying
or surface cooking after drying.
Our drying methods are:
- Spray drying
- Fluid bed drying
- Freeze drying
- Pneumatic ring and flash drying
Thin liquors from fermentation broth
and other preparation forms can be concentrated by our gentle Falling Film
Evaporators. For process economy, we use vapour recompression and multi-stage
Granulation and Aglomeration are often
integrated into the drying process to instantize the powder. Agglomeration of
the fine dusty powder reduces the total product surface area so the product is
easier to wet.
Process plants supplied by us manufacture many tonnes
each year of agglomerated food products with specialized surface treatment for
extended life-cylcle and easy re-combination.
