Constant pressure

A digitally controlled constant pressure option has been added to the M-700 series Microfluidizer high-shear fluid processors. Operating at constant process pressure is expected to minimize component stress, resulting in longer component life and increased machine reliability. With the constant pressure option, real-time flow rates are displayed on an LCD panel, and built-in alarms warn and/or shut down the unattended system in the event of out-of-spec processing pressure. This significantly reduces the incidence of product waste and improves overall product quality.

Triple the action

Triple-action mixing plus portability and control are keys of the Tri-Mix Turbo-Shear agitator. It can be built in many custom sizes with various viscosity ratings especially for R&D use. Its portability allows you to not commit valuable lab space to one mixer. A variety of control options are available.

Custom wet-mix

Custom-engineered wet-mix process systems are packaged to achieve specific customer requirements for emulsifying, dispersion and particle size reduction. They provide users with a finished product that is homogeneous, has repeatable viscosity and dispersion down to one micron and is consistent from batch to batch. Systems can be designed for handling viscous materials from 1,000 cps and up with flow rates 0.5-300 gpm, depending upon the application, and are ideally suited for food, pharmaceutical, cosmetics and chemical applications.

Stationary and portable CB Series Blender-Conveyors combine bulk carrier unloading, transfer, and blending capabilities in one vacuum-pressure unit. They are sized for 5 to 20-plus TPH and can handle powdered, granular or pelletized abrasive materials that are friable. Equipped with automated controls and load cells, these machines blend products from multiple sources and convey them to one or more destinations using a single 15-psig positive-displacement blower. Proprietary semi-dense design results in low line velocities and high material-to-air ratios that reduce wear and product degradation.

Auger metering added

RAM, regrind auger metering, has been added to the vendor's SGBD series 900 and larger blenders. The blenders already accurately mix up to six components; RAM allows the addition of two more hard-to-meter components. Up to two RAM units can be mounted onto each blender with a 7-in. frame riser section that sits below the material hoppers. These feeders funnel into the weigh hopper with the other six ingredients from the standard slide gate, processing material between 10-2,500 lbs. per hour.

Small and lightweight

Small, lightweight, all-steel production mixers for pharmaceutical, biotech and higher-end food applications meet ASME BPE standards and are designed for tank mounting. The PB-Series mixers feature an IEC frame motor that weighs only 7 lbs. and all-steel drive systems with a 316L stainless steel dry-running mechanical seal, pedestal and wetted parts. Ideally suited for batch processing from 5 to 200 liters, these portable mixers have a sanitary Tri-Clamp mount and are SIP/CIP cleanable.
