How versatile viscometers optimize encapsulation processes?

Encapsulation processes

In the pharmaceutical industry, the perfection of encapsulated products requires total control of several processing steps including encapsulation, which consists of enclosing a substance in a stable envelope called a capsule.

The purpose of these capsules is to protect the substance from interactions with the external environment or to transport the substance to the place where it will be released to act.

Today, there are two types of capsules: the hard-shell capsule and the soft-shell capsule, both of which are made of a gelling agent (gelatin), an animal protein or polysaccharides and derivatives. 

The quality of the final product depends on the upstream production of the gelling agents through the processing of materials of natural origin, the manufacturing of the shells and their sealing after filling with the active ingredient.

Viscosity is a key specification of the gelling agent that will be involved in the manufacturing of the empty capsules through the dipping process and in a later step in their sealing after filling with the active ingredient.

The resonant frequency vibrating type MIVI viscometer, invented by Sofraser, is known for its great versatility which allows the MIVI viscometer to be used for difficult or sophisticated transformation processes, including hygienic processes. In addition to its contribution to upstream gelatin production, the sensitive and reliable measurement allows perfect monitoring and control of viscosity during capsule manufacturing and sealing.

The MIVI Viscometer is successfully used by gelatin producers whose concern is quality, safety and compliance with the final product specifications. Capsule manufacturers take advantage of the viscosity control to ensure the best performance of the dipping process in the gelatin bath. Finally, MIVI is used in the pharmaceutical industry to control the viscosity of the sealing agent during the application step and to guarantee the safety of the final consumers. Moreover, thanks to its instantaneous and continuous measurement, MIVI ensures the traceability of the manufacturing conditions.
