Drying - water extraction
CO2 drying is a unique form of extraction, focuses on removing water from a substrate
Challenge
Current drying methods like spray dryers, ovens, or sunlight are energy intensive and/or time consuming.
Overcoming challenges:
- Careful substance selection and parameter optimization
- Consideration of material properties
- Development of tailored techniques or technologies
Sc CO2 solution
Advantages of carbon dioxide
- High diffusivity
- Low surface tension
- Easy removal
- Cost-effective supercritical process
- No waste, no residue, no solvent, non toxic
- Freshness preservation
- Superior dehydration
- Retention of vitamins and antioxidants
- Maintains color
- Increases shelf life
Market applications
Food, Pharma, Cosmetics, Chemical, Agriculture
- Food: extends the shelf life of fruits, vegetables, and meat
- Pharmaceutical: Dries sensitive ingredients
- Cosmetics: Preserves the properties of natural extracts
- Chemical: Ensures purity of solvents and catalysts
- Biotechnology: Dries biomaterials
- Agriculture: Reduces moisture in crops, seeds, and flowers
Competitive advantages
CO2 above a certain temperature and pressure (*)
offers the advantages of both a gas and a liquid:
CLEAN
- Zero waste, no residue, no solvent. Nontoxic
ADDED VALUE
- Low T° (32°C): heat-sensitive products
- (currently solvent often T° > 60°C)
- Minimizes risk of thermal/chemical degradation
- Penetrating power (density of a liquid, diffusivity of a gas)
- Better unimodal size/population distribution
- Obtain precise control over encapsulation
- Avoids formation of unwanted by-products
- Better control of product properties (encapsulation)
- Biocidal properties of CO2 (sterilization)
- More homogeneous and optimal properties (APIs)
- Enhancing product stability and bioavailability
- Particle size >60 nm (vs microfluidique > 5000 nm)
COMPETITIVE and EFFICIENT
- Faster and compact process (no need separation steps)
- Reduced process time (5 to 10 times)
- Reduced operation cost (from to 2 to 4 times)
- Compact, modular and integrated process
