    摘要： A mixer blade which is adapted to be mounted on the shaft of a vertical continuous granulating mixer, characterised in that an inner portion of the leading edge of the blade is bevelled upwards and an outer portion of the leading edge of the blade is substantially vertical or is bevelled downwards. A vertical continuous granulating mixer which comprises a shaft fitted with blades rotating within a tubular housing and having an inlet for solid particles and a spray inlet for liquid to contact the solid particles above the blades, characterised in that an inner portion of at least one of the blades is angled forwards and upwards over at least part of its area so that particles hitting the angled portion of the blade acquire an upwards velocity component.

    摘要： In an agglomeration process for the preparation of granules encapsulating a hydrophobic active material, the active material and a molten binder which has a melting point above ambient temperature are sprayed onto water soluble carrier particles while agitating the particles. A liquid which interacts exothermically with the carrier particles is sprayed onto the carrier particles separately from and just before or simultaneously with the active material and binder, so that the heat generated by the interaction reduces the cooling rate of the binder during the agglomeration process. For example the liquid can be water when the carrier particles have a positive heat of hydration and/or solution by water.
