34 January 2019 Tablets & Capsules A survey of what's available granulation & drying Continuous granulation-drying system Granuformer GF-215 continuous granulation-drying sys- tem produces highly-porous granules free of agglomeration and oversized particles. Unit kneads and blends the pow- der, combines it with a binder, and then feeds it into a twin-screw extruder. The extruded material is then milled to the desired particle size, dried in a spiral dryer, and col- lected using a cyclone. Granulated material has excellent compressibility. Unit is suitable for R&D and full-scale tablet production. Freund-Vector, Marion, IA 319 377 8263 www.freund-vector.com Granulation-drying system Granulation-drying system converts non-flowing moist solids into free-flowing dry granules using a centrifugal sifter, spheroidizer, fluid-bed dryer, and vibratory screener. Centri-Sifter uses rotating helical paddles to break up lumps and drive material through a screen, continuously produc- ing pellets at high rates. Pellets discharge into a vibrating spheroidizer that forms them into high-strength, uniform, spherical particles. Moist particles enter the Vibro-Bed cir- cular vibratory fluid-bed dryer on a perforated screen and are dried within a rising column of heated air on a first-in- first-out basis. Dry particles then pass through the Vibro- screen circular vibratory screener that removes oversized particles and dust. Equipment meets 3A, FDA, USDA, BISSC, and other sanitary standards. Kason, Millburn, NJ 973 467 8140 www.kason.com Blender dryers Company offers a variety of vacuum drying equipment. VCB heated tumble blenders, with working capacities of 0.5 to 50 cubic feet, gently blend, dry, and homogenize powders with other miniscule batch components. V vertical cone screw blenders gently lift and dry 1 to 350 cubic feet of material. Vertical blenders remove air pressure in the blending vessel, which lowers the evaporation temperature of unwanted moisture, while a turning screw travels along the inner sur- face of the vessel to create effective heat transfer. 42N/C horizontal ribbon blenders and cylindrical dryers are suitable for large batches requiring high shear levels and are also vac- uum capable and jacketed for fast drying.
