High-shear mixers for fine dispersions and emulsions

Batch high-shear mixers equipped with the Solids/Liquid Injection Manifold (SLIM) Technology (photo) deliver powders in an efficient manner for quick wet-out and complete dispersion into low-viscosity liquids. In a conventional rotor/stator mixer, materials are continually drawn from below the mixing head and then expelled at high velocity through the stator openings. A SLIM mixer assembly with Progressive Spiral Porting creates a powerful vacuum that draws powders directly into the high shear zone and rapidly disperses individual solid particles into the liquid vehicle. This method of powder addition dramatically reduces the formation of lumps (fisheyes), prevents floating powders, eliminates dusting, and accelerates mixing time, says the manufacturer. The SLIM can also be used to introduce minor liquid components and create fine emulsions. To easily raise and lower the mixer in and out of the mix vessel, a floor-mounted design equipped with an air/oil hydraulic lift is available. Safety limit switches prevent operation of the mixer while in a raised position or without a mix vessel in place. — Charles Ross & Son Company, Hauppauge, N.Y.

Benzene monitor for asphalt production and more

The Titan (photo) is a specific fixed gas detector, based on photoionization detection (PID), designed only for the monitoring of benzene. This makes it the perfect choice for use in asphalt manufacturing plants, where benzene is likely to be the most prominent volatile organic compound (VOC) that requires management and monitoring. As a fixed unit, the Titan can be installed at regular distances around sites, and with its “plug and play” installation approach, the Titan can be left monitoring without the need for intervention. Two alarm systems can be set at the user’s convenience, and another two are pre-set relays for immediate warnings, so no exposure incident is ever missed. The Titan offers continuous real-time data feedback of VOC concentrations in the air, taking samples every minute to an accuracy of 0.1 parts per million (ppm) or +10%, whichever is greater. — Ion Science Ltd., Royston, U.K.

Save up to 95% in CIP liquid with this drain valve cleaner

Drain valves comprise up to 20% of all valves in a typical processing plant. But cleaning them is costly, difficult and time-consuming due to long cleaning cycles and the risk of pressure shocks. The new ThinkTop pulse seat clean (photo) addresses all these issues, quickly and effectively cleaning drain valves while delivering savings of up to 95% in cleaning-in-place (CIP) liquid, says the company. Short bursts, or pulses, drive the valve cleaning process, activating the valve when shear forces peak. Each position-based pulse takes less than a second, preventing pressure shocks in the system. The pulse creates high turbulent flow as the liquid passes through the narrow gap between the valve house and valve seat, effectively removing all residuals for spotless drain valves. Intended for use with single-seat valves or butterfly valves used as drain valves, pulse seat clean is a standard feature of ThinkTop V50 and V70 sensing and control units with one solenoid valve. — Alfa Laval AB, Lund, Sweden

The modular AC filtration technology (photo) is designed for smaller side streams of copper and other metal-loaded aqueous streams. It is specifically suited for efficient organics removal before the electrowinning and crystallization processes. The AC filter utilizes the already proven design and operation philosophy of the company’s DM filter product family and is suitable for both greenfield and brownfield installations. Benefits of the AC filter include: increased end-product yield and quality; increased recovery and recycling of valuable process chemicals; low energy consumption, due to low pumping pressure; and minimized water consumption with optimized back washing. — Metso Outotec Corp., Helsinki, Finland


Leakage valve boosts safety of ESL production

The Aseptomag LV leakage valve is a mixproof double-seat valve is designed for manufacturers of foods and beverages, as well as pharmaceutical products. Typical examples are products with an extended shelf life (ESL), such as soft drinks, fruit juices and milk-based and lactic-acid fermented products, along with plant-based alternatives sold chilled by retailers. The design features significantly mitigate the risk of contamination in this hygiene class. In addition, products become more durable — with less preservatives. Thanks to its dimensions, the compact double-seat valve for ESL processes takes up less space and is easier to install and maintain than aseptic alternatives. Technical features, such as the backstroke barrier, can be easily retrofitted without the need to replace the actuator or other existing equipment. The leakage valve is available in the upright LV version for typical valve matrices (photo, left) and in the LVBS version (right) for tank bottoms. The latter is typically used for tank installations and can also be connected to a pigging station for resource-saving product recovery systems. — GEA Group, Düsseldorf, Germany


This fast coupling device is patent-pending

REconnect (photo) is a new a coupling device for simple and safe decoupling and recoupling of diaphragm seal systems, including process connections and measuring devices. REconnect consists of two parts — one fitted to the measuring device, the other to the process connection – and with the aid of the special lock, they are easily separated. The lock is detachable and can be retained separately so that REconnect cannot be operated accidentally or by unauthorized persons. After separation, the two parts of the coupling are each closed with covers made of stainless steel to protect the measuring instrument and diaphragm seal. The fast coupling is vacuum-proof and has no parts that can be lost. It is suitable for applications in the pharmaceutical, food and chemical industries. — Labom Mess- und Regeltechnik GmbH, Hude, Germany

An efficient cleaning system for mixers

Automatic WIP-Systems (photo) provide a reliable and repeatable process for cleaning mixing systems — such as the Ploughshare Mixers — an important task especially in life-science applications. A smart arrangement of rotating cleaning nozzles inside the mixing drum ensures a thorough rinsing of all product contact surfaces without any need for filling the machine with cleaning media. By simultaneous rotation of mixing elements and cleaning nozzles, any spray shadows are avoided. The gear-driven rotating flat fan nozzles guarantee an intensive and uniform cleaning of all surfaces. Besides the rotating cleaning nozzles inside the mixing drum, the seals for the mixing elements and choppers are purged with water and all ports on the machine are cleaned effectively by static, locally installed cleaning nozzles. — Lödige Process Technology, Paderborn, Germany


A polymer pelletizer for when capacities are high

The Pearlo 350 EAC underwater pelletizing system (photo) has a liquid-heated die plate for high capacities, delivering throughputs of 18,000 kg/h of virgin polymer. The unique cutting-blade design and optimum water- and material-flow conditions within the cutting chamber provide not only ideal and homogeneous cooling effects, but also outstanding pellet quality, says the company. Another design feature is the cutting-blade advance system, which permits axial movement of the cutter shaft, resulting in a precise blade advance, as well as a regrinding of the blades during production. This allows higher equipment availability and lengthened production runs, which saves costs. — Maag Pump Systems, Oberglatt, Switzerland
