91921.tifSquare-Bin Blender
The SFM-2000 blender speeds ingredient handling by accommodating pharmaceutical manufacturers’ most commonly used square bins. This minimizes campaign disruptions and shortens loading time and changeout. The blender can be configured to blend square-shaped bins of any design. Bohle can also provide square bins to match existing configurations or to utilize its patented blending technology. The square bin blender provides homogeneous blending of dry powder batches using patented blending elements mounted to the inside of the container lid. The blending procedure can be scaled from 5 to 2500 L. Users also can exchange blending containers to accommodate different volumes.  L.B. Bohle LLC, Warminster, PA 215-957-1240 www.lbbohle.com

91922.tifConical Vacuum Dryer-Mixers
These conical vacuum dryer-mixers offer high mixing accuracy and low shear force to the products being dried and mixed, while requiring low energy consumption, along with the ability for variable volume filling down to 20% of overall volume design on powders, pastes, and slurries. Many different processing tasks can be carried out simultaneously to include drying, mixing, heating/cooling, de-aeration, crystallization, granulation, agglomeration, and the injection of liquids or gases directly into the batch during processing in a totally enclosed safe environment. Typical applications range from plastics, spices, adhesives, soap powders, and food premixes, to shampoos, toothpastes, gelatins, pharmaceuticals, and chemicals. Bolz-Summix (USA), Swedesboro, NJ 856-241-9970 www.mpegroupusa.com

91923.tifPowder Induction and Dispersion System
The Fastfeed powder induction and dispersion system is designed to offer controlled powder feed rates from 3 to 400 lb/min. The Fastfeed offers consistent powder delivery even as viscosity and solids levels increase, ensuring that the system will never plug or foul. It offers the benefits of an in-line, skid-mounted dispersion system that feeds powders and disperses them instantly. The system allows processors to add dry ingredients to mix vessels in a more ergonomic fashion, reducing operator injuries and providing the shear required for today’s changing and tougher ingredients, ensuring maximum yield. Applications include sugars, sweeteners, whey and soy proteins, gums, dairy powders, NFDM, gelatin, flavorings, starches, salt, phosphates, carbomers, carrageenan, SHMP, caffeine, nutraceuticals, maltodextrin, vitamins, and more. Admix Inc., Manchester, NH 603-627-2340 www.admix.com

91924.tifMiniature Rotary Batch Mixer
This miniature rotary batch mixer blends bulk ingredients, adds liquids, and achieves 100% batch uniformity in less than three minutes while heating or cooling the batch. It features an internal spray line for liquid additions and a jacketed mixing drum that can be piped to an oil, steam, or chiller system. The unit is equally effective at blending batches from 100 to 15% of its 1-cu-ft capacity. Four-way mixing action rapidly distributes particles without degradation, while causing the greatest number of particles to contact the vessel walls, maximizing thermal transfer efficiency. It is suitable for 3-A, USDA, or industrial lab or production applications. Munson Machinery, Utica, NY 800-944-6644 www.munsonmachinery.com

91926.tifContinuous Blender
The Vibra blender utilizes a combination of a rotating paddle and material fluidization to blend dry solids with the ease of liquids. Gentle controlled vibration of the mixing trough fluidizes ingredients on entry where a cut and fold mixing rotor provides agitation. Materials flow through the blender by gravity, making it completely self regulating to changes of infeed rate. The unit’s simple rugged design offers dust-tight operation, easy cleanout, and years of maintenance-free operation. The blender is available in capacities up to 1500 cu ft/hr. Vibra Screw Inc., Totowa, NJ 973-256-7410 www.vibrascrew.com

91927.tifContinuous Mixer
Designed for use as an on-machine or central station blender, the ProBlend mixer precisely meters and mixes materials at various throughputs and blend ratios. Utilizing a compact hopper with an adjustable speed impeller, the ProBlend’s continuous mixing action consistently delivers a homogeneous blend. Equipped with an optional instant access hopper door with quick-release latches, the mixing chamber and impeller can be easily cleaned without being removed. Positions are provided for up to four high-precision ProRate feeders that can simultaneously meter additives or colorants into the blending hopper. ProRates can be added or removed to accommodate future application requirements. K-Tron Process Group – K-Tron Premier, Salina, KS 785-825-1611  www.ktronpremier.com

91928.tifBatching & Blending Systems
PRO series batch automation allows formulas to be manually or electronically entered into the system to automatically ensure that the proper amount of ingredients are measured into each scale and that the material is transferred to the mixing operation where the proper mixing cycle is handled, including mix time and transfer of ingredients to packaging or bulk load out. PRO series blend automation allows formulas to be manually or electronically entered into the system to automatically ensure that the proper ratio of liquid and dry ingredients are proportioned and blended into a homogeneous mixture. When used in conjunction with the Mistcoater liquid applicator and mass flow and volumetric metering systems, this system allows material to be accurately and consistently blended together automatically in a continuous flow process. APEC, Lake Odessa, MI 616-374-1000 www.apecusa.com

91929.tifRibbon Blenders
Ribbon blenders are manufactured in a wide range of sizes from ½ to over 500 cu ft working capacity. The blenders are offered with several agitator design possibilities. Standard options include sanitary or air-purged stuffing boxes, jackets for heating and cooling, sanitary construction, and covers to meet client’s production needs. The unit shown is a 500-cu-ft model constructed of stainless steel and designed for operation under vacuum and internal pressure.

91932.tifDouble Shafted Fluidized Zone Mixer
The Bella XN double shafted fluidized zone mixer includes access doors that not only increase accessibility but also make it easier to clean when necessary. The mixer achieves fast, high-capacity, low-shear, precision mixing of either dry bulk solids or liquids with solids. Regardless of particle size, shape, or density, materials are mixed with a fast, efficient, and gentle action. Typical mixing times are 60 seconds or less. A weightless zone created by low-speed counter rotating shafts generates very low friction without shear. This makes it ideal for fragile products that cannot tolerate rough handling. Even flakes or spray-dried bodies remain intact. The mixer includes twin bomb-bay door openings for fast, efficient discharging and to minimize segregation during discharge. The Bella mixer is available in stainless steel for sanitary applications. Custom sizes, finishes, and materials of construction are available upon request. Dynamic Air Inc., St. Paul, MN  651-484-2900 www.dynamicair.com

92112.tifHorizontal Blenders
Each of these two 900-cu-ft horizontal blenders is 9 ft wide, 9 ft, 2 in. tall, and 25 ft long with 125 hp direct-connected drives. The Multi-Pitch agitators are furnished to blend granular polypropylene with additives to the customer’s exact mixing requirements. Accessories furnished with each blender include a temperature gauge, temperature transmitter, and four 15,000-lb-capacity load cells all pre-wired to a local control panel with hand switch and weight indicator.

92113.tifAutomated Mixing System
Designed specifically for fully automated introduction, transfer, mixing, and blending of multiple, sluggish materials, this integrated mixing system produces such homogenous blends that downstream production scrap is virtually eliminated. A lift-and-seal gaylord discharge system, with a dust-tight, custom discharge hood introduces the material to the transfer bin. An integrated agitator and vacuum pump transfer system supply material to the high-volume material mixer. Within the mixer, a 16-in.-diam auger mixes material in a 17-in.-diam, 10-gauge mix tube. In-feed scoop blades at the base of the mixing auger, and broad-throw dispersion paddles at the top of the mixing auger ensure a homogenous and consistent blend supply to downstream processes.  National Bulk Equipment Inc., Holland, MI 616-399-2220  www.nbe-inc.com
