Working Principle

Unopex B 45 Dehumidifier

Unopex B 45 Dehumidifier is a complementary accessory to condition drying air, to work continuously with water and organic solvent mixtures or inlet air cooling for the spray chilling operations.

Unopex B 60 Inert Cycle

Unopex B 60 Inert Cycle organic solvent recovery unit is a complementary accessory that enables to work with organic solvent-based formulations safely.

Spray Chilling Unit

Unopex Spray Chilling Unit is the ideal complementary accessory that enables to make powders directly from molten feed samples by solidification. It used to work in combination with Unopex B 15 Mini Spray Dryer and B 45 Dehumidifier.

Closed Cycle Mini Spray Dryer

Unopex B 15 Mini Spray Dryer, B 45 Dehumidifier and B 60 Inert Cycle together is the solution for spray drying of organic solvents safely under nitrogen.

Spray drying can be used as a microencapsulation method.

In microencapsulation the product is mixed with a carrier which protects the product.

Microencapsulation protect the product from surrounding environment, degradation or flavor loss, and extends its shelf life.

Scale Up

A small spray dryer is particularly useful for initial trials.

Unopex B 15 Mini Spray Dryer is an ideal instrument for research and product development purposes.

The results from a successful spray drying test conducted on Unopex B 15 Spray Dryer can be utilized in the scale up procedure to Unopex B 230 Pilot Scale Spray Dryer and to industrial production.
