Green Innovation: Algae Granulation Solutions

Transferring non-flowable nutraceutical ingredients into powders with easy handling, processing and direct compressibility.

Tablets are the easiest and most convenient way for the customer for consume. The challenge is that some of the ingredients provided by nature are not free-flowing and change their properties over time. This leads to difficulties during the final compression step. Often chemical additives are used to improve their flowability and compressability.

Increased flowability with Innojet Granulation method

Your challenges

Very fine powder with poor flowability
Product is hygroscopic and shows electrostatic charging
Customer strives for 100% natural process & -ingredients with no additional binder or process aid
Requirements for “Clean Label”
Increasing production rate
Cost effective production
Sustainable production

Our solution

Usage of Ventilus® Technology:

Highly efficient Granulation- and Drying process
Significantly improved flowability, transferability and compressibility
Our technology allows perfect Granulation without additional process aid

Three processes were screened, optimised and evaluated to achieve the best flowing powder for tablet presses. The best of these was chosen for commercialization. In this way, we have created a green process that is suitable for many types of superfoods and food supplements of natural origin.

What you can expect

Perfect flowability and direct compressibility
Target Particle Size Distribution (PSD) reached within short time
100% natural, no additional (chemical) binder used
100% compressible
100% sustainable

At the Romaco Innojet lab, we have studied many of these ingredients, such as algae, and developed solutions to improve their properties for further processing.
