There are several manufactures:

Nisco (Switzerland) -http://www.nisco.ch/

Brace (Germany)-https://www.brace.de/en/microencapsulation.html

LabPlant (UK)-http://www.labplant.co.uk/

Depending what type of encapsulation processes do you need, there are other producers too.

 Thanks steva Levic

for prompt response. We are planning to encapsulate the pomegranate seed oil using coextrusion method where in shell and core type of capsules are expected. NISCO is dealing in it , brace does not manufacture encapsulators, and labplant deals in spray dryers. It will be of great help if u could able provide me one or two more manufaturers of microencapsulators. 

This may help:

It is not so complicated to produce encapsulated oils (for example we developed several formulations for such systems as well as applications in meat products)-https://www.researchgate.net/publication/262077067_The_utilisation_of_grapeseed_oil_in_improving_the_quality_of_dry_fermented_sausages?_iepl%5BviewId%5D=ew9mTg96Mkv1AzG40VshutY6&_iepl%5BprofilePublicationItemVariant%5D=default&_iepl%5Bcontexts%5D%5B0%5D=prfpi&_iepl%5BtargetEntityId%5D=PB%3A262077067&_iepl%5BinteractionType%5D=publicationTitle

However, the problems could start with storage of such products. Appropriate measures must be taken to prevent negative chemical transformations of encapsulated oil.
