Riera Nadeu, S.A. products

The RINA Serie 700 models are horizontal batch centrifuges with automatic discharge (peeler centrifuge) dedicated to solid-liquid filtering separation of slurries with high rotating speed (see table below).

The RINA Serie 700 models are horizontal batch centrifuges with automatic discharge (peeler centrifuge) dedicated to solid-liquid filtering separation of slurries with high rotating speed (see table below).

The RINA Serie 300 models are vertical batch centrifuges with automatic discharge (bottom discharge peeler centrifuges) dedicated to solid-liquid separation of slurries with high rotating speed (see table below).

The RINA Serie 200 models are vertical batch centrifuges with manual discharge dedicated to solid-liquid separation of slurries with high rotating speed (see table below). Riera Nadeu accumulates experience in several processes of the following sectors: Pharmaceutical & Fine chemicals, Bulk chemicals, Waste treatment (nuclear and others) and more applications with the most demanding requirements.

The RINA Serie 500 models are continuous vertical filtering centrifuges with conical rotor dedicated to solid-liquid separation of crystallin, granular o fibrous particles suspended in a liquid phase. Those equipments are providing a very high treatment capacity. The product must show a high filtration rate, between 30 and 80% solid content, and particles size between 50 and 5000 µm. The time residence is set by adjusting the feed rate and the speed difference of the epicycloid gear.

The RINA SRP models are vertical decanting tubular bowl centrifuges turning at very high speed (15.000G mini). They are being used for solid-liquid separation (“C” version) or liquid-liquid separation (“S” version).

The RINA Spray Dryer models are working in a continuous way by atomizing slurries in a vertical drying tower. This technological solution is particularly recommended for pumpable thermosensitive products requiring a soft and longtime drying in order to produce a dry powder made of fine particles which could additionally be encapsulated.

The RINA Jet-Mill models are micronizers processing dry powder in order to reduce significantly the size of the particles. It is the transformation of powder and granulates to microscopic particles that could be used in some special applications within the pharmaceutical industry for example pigmentation, coloration, inhalation, etc.
