Sift-N-Blend

GlobePharma’s Patented (US 8,235,582; US 8,827,545; CA 2736942C; CA 2821188C & EP2703072B1) SIFT-N-BLEND® technology facilitates simultaneous sifting and blending in the blending vessel itself, thereby eliminating the need for separate sifting of ingredients, such as silicon dioxide, and provides excellent content uniformity of pharmaceuticals, especially low dose drugs, as well as food and cosmetic ingredients such as colors, flavors, sweeteners, etc. The SIFT-N-BLEND® attachment replaces the traditional intensifier bars, which are heavy, especially on commercial scale blenders requiring multiple operators to install and dismantle, and difficult to clean. It consists of a semi-tubular screen, either made of wire mesh or a perforated stainless-steel sheet, a pair of mounting rods, and a paddle. This assembly is mounted on the trunnion hub inside the blending vessel, allowing the screen to rotate at the same speed as the shell (e.g., 25 rpm on a lab blender). A separate drive operates the paddle, which turns independently at variable speeds up to 2,500 rpm. As the paddle rotates, at each rotation some powder enters the screen and the paddle forces it through the screen, effectively breaking up lumps and any static agglomerates ensuring a uniform blend. The powder goes through screening multiple times, helping eliminate the need for pre-screening of the powder ingredients, and homogeneous blend is achieved.
