Solids/Liquid Injection Manifold
The Solids/Liquid Injection Manifold (SLIM) is a high-shear mixer system designed to prevent the formation of agglomerates and “fish eyes” in thickened solutions. This novel method of powder induction utilizes a specially engineered rotor/stator assembly that generates a powerful vacuum for drawing solids into the mix chamber. The liquid stream enters the mixer and immediately encounters the powder addition under intense shear conditions. The resulting dispersion is expelled centrifugally through the stator openings at high velocity. Stubborn agglomerates and “fish eyes” are prevented from forming. The sub-surface addition of solids also eliminates the occurrence of floating powders in batch tanks. A “hose & wand” attachment to the powder inlet of the SLIM allows operators to conveniently draw lightweight, free-flowing powders straight from within the bulk container. For faster induction rates, solids are loaded into a hopper located right above the mix chamber. Charles Ross & Son Co., Hauppauge, NY 800-243-7677 www.mixers.com

Particle Size and Shape Analyzer
The Haver Tyler CPA 2-1 is a photo-optical particle size and shape analyzer. The unit is ideally designed for laboratory use for measuring dry, free flowing, and non-agglomerating particles. Exclusive Haver software performs a correlation calculation, matching CPA 2-1 raw data to traditional test sieving results. The CPA 2-1 counts and measures, in real time, each individual particle of a representative material sample. The unit conveys dry, free-flowing material samples to fall past a high-resolution camera lens, which takes approximately 20,000 scans per second. This technology provides consistent, repeatable results. The CPA 2-1 user can select from a virtually infinite list of measurement “openings” for custom analysis. ASTM, ISO, and all other international standard sizes are available in addition to specific custom sizes the application may require. W.S. Tyler, Mentor, OH 800-321-6188 www.wstyler.com

Vibratory Conveyor
An engineered modification of the Iso-Flo vibratory conveyor, the Iso-Glide achieves a motion that resembles horizontal motion, which maximizes sanitation while offering gentle handling and quiet operation. Iso-Glide can perform a range of product handling and packaging distribution functions, including scale feed applications. It allows processors to experience the continuous self-cleaning benefits of horizontal motion conveying but on an Iso-Flo platform. Product virtually slides along the stainless steel conveyor bed, which prevents the buildup of coatings, oils, and seasonings. By limiting vertical acceleration to almost 1 g, Iso-Glide helps reduce plant-level noise that traditional direct drive or other vibratory conveyors can produce with conveying surface-to-product contact.

Planetary Dual Disperser
The Planetary Dual Disperser (PDDM) is ideal for powerful mixing of high viscosity applications requiring ultra-fine dispersion quality. It features four agitators – two planetary stirrers and two high-speed shafts – all rotating on their own axes while orbiting the mix vessel on a common axis. Pictured is a 40-gal model equipped with q built-in vacuum pump assembly for operation up to 29.5 in. Hg. The two saw-tooth blades on each high-speed shaft provide an intensive shearing action, promoting solids dispersion and particle size reduction. The planetary stirrers continually turn over batch material, help feed fresh product to the high-speed blades, and facilitate uniform temperature throughout the mix zone. Sidewall and bottom scrapers can also be installed to further ensure superior heat transfer between the vessel jacket and batch material.

Vibratory Weigh Scale Packers
GWT grid top, vibratory weigh scale packers equip production and shipping departments with a complete solution for filling, weighing, compacting, and conveying containers of bulk solids with capacities as high as 4000 lb. Durably constructed in mild or stainless steel, these products are an ideal interface to roller conveyors. GWT packers conveniently mount below conveyor rollers allowing bags, drums, trays, or other containers to easily be transported directly onto its grid top deck. With the GWT packer grids designed to raise between conveyor rollers, there is no need for operators to manually move containers. The packer lifts the container to the appropriate height, runs the selected vibration cycle time for fast, effective compaction of material as it is being filled, and weighs the container throughout the entire process. The filled, compacted container is lowered back onto the roller conveyor, enabling it to be moved to the next step as an empty container approaches.
