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 and that could also be encapsulated. The spraying can be done with high pressure system or with bi-fluid. The drying tower is sized depending on the type of spray nozzle (velocity, angle of dispersion and size of droplets) and the hot fluid flowrate to determine its diameter. The time residence needed to evaporate the liquid is determining the height of it. The mixed fluid made of vapor and dry particles is pneumatically conveyed to some powder separation system. Several configurations can be proposed: cyclone, bag filter, scrubber to reduce the loss of fine particles at its minimum to comply with local requirements in terms of emission. Riera Nadeu can propose some very special configurations for the drying of corrosive products with some drying lines made of Hastelloy, and of toxic product in compliance with OEB4 requirements fitted with CIP system. From the safety point of view, they can be adapted to work in explosive hazardous area with the relevant certification or approval for the operating location. The drying line can be working in closed loop circuit with Nitrogen if needed. The drying lines RINA Spray Dryer are customized to fit perfectly with the specifications of the client considering either the process requirement and general arrangement of the production plant.
