Table 25: Summary of the processes, methods and machines used at the Microalgal biomass
treatment unit.
According to table 25, that shows a Summary of the processes, methods and machines used at
the Microalgal biomass treatment unit, we note that this unit requires the use of several
Process
Purpose of use
Methode
Brand of machine
Dewatering
Since
spirulina
platensis,
contains a hight water content,
dewatering is often necessary to
remove excess moisture.
Spray drying
GEA-spray drayer
Cell
disruption
To
access
the
valuable
compounds within microalgae
cells, cell walls need to be
disrupted.
Ultrasonication
Qsonica-Ultrasonic
homogenizer
Extraction
After cell distruption, the desired
compounds
(proteins,
pigments…) are extracted
Solvent extraction
Buchi-Rotary evaporator
Purification
The extracted mixture is
typically purified to isolate and
refine the specific compounds of
interest.
Chromatography
Waters-Chromatograph
Drying
The purified extracts are often
dried to creat a stable product
Spray drying
GEA-spray drayer
Product
utilisation
The purified spirulina platensis
compounds can be used for
varios applications including
dietary supplements, cosmetics
and food additives.
Converting extracts of
microalgae
into
capsules
Capsugel-Capsule filling
machine
