  • Patent number: 5629187
    Abstract: A process and apparatus are provided for making solid Particles from an ionically cross-linkable material by cross-linking drops of the material with a cross-linking agent in the form of a falling stream. In one embodiment, a stream of the cross-linking agent flows down the inner walls of an enclosure and drops of the material are directed to the stream of cross-linking agent. In another embodiment, a stream of the cross-linking agent is free-falling by gravity in a cascade without contacting any surface and drops of the material are directed to the stream of cross-linking agent. Solid particles are separated from the cross-linking agent at about the bottom of the enclosure or at about the bottom of the cascade. The drops of cross-linkable material are directed at the stream of cross-linking agent preferably at an angle of incidence of less than 90.degree. such as between 5.degree. and 45.degree. and most preferably between 15.degree. and 30.degree.. Particles having a size of 10 .mu.
    Type: Grant
