VEGA Grieshaber

Guided radar for level measurement of bulk solids

The new guided radar sensor Vegaflex 82 features a new, automatic probe-end-tracking function, which enables the device to measure the levels of bulk solids — even those with dielectric constants of 1.1 and higher — with unprecedented reliability, says the company. When there is an increasingly unreliable product signal, the sensor switches automatically to the stable probe-end-tracking signal, which is always proportional to the level. This guarantees accurate, consistent readings, especially with critical products, such as plastic powder. Vegaflex 82 is suitable for level measurement in almost all bulk solids. It delivers reliable measurement data in process temperatures from –40 to 200°C and process pressures from –1 to 40 bars. Its applications range from large-volume bunkers to 75-m-high silos, from light, fine powders to coarse, heavy gravel. Hall 6, Stand 209 — VEGA Grieshaber KG, Schiltach, Germany

Goudsmit Magnetic Systems


Use this strong magnet to remove impurities from product

The recently developed, fast-cleaning clean-flow magnet reaches a magnetic field of 10,700 Gauss on the bars that are within the product. The magnetic system removes iron particles and weakly magnetic particles from powdery substances, such as powdered milk, sugar and flour. With the application of the new generation of Neoflux magnets, it is also possible to capture weakly magnetic particles, such as 304 stainless steel (SS). Because the grill of this type of clean-flow magnet can be drawn outward via a rail, the magnet ensures a smooth operation and safety for the operators. The casing is made of 304 SS and the entire machine has a smooth finish (Ra ≤ 0.8), thus complying with the HACCP/EHEDG requirements. Three standard sizes are available for handling capacities of 10 to 20 m3/h. Hall 1, Stand 339 — Goudsmit Magnetic Systems B.V., Waalre, the Netherlands

This versatile, heavy-duty processor is self-cleaning

The Reactotherm consists of a cylindrical, horizontal shell and a rotor with segmented discs and mixing bars. Stationary mixing hooks are attached to the inside of the shell. The close clearance between the mixing hooks, the segmented discs and the rotor results in a high mixing and kneading effect and largely self-cleaning properties of the rotor. Mixing bars are used to clean the inside of the shell, which prevents fouling of heat exchange surfaces and the formation of agglomerates. The shell, shaft and discs can be heated or cooled. The system can operate continuously or batch-wise under vacuum, atmospheric pressure and overpressure. Units are available with volumes from 160 to 10,000 L and 3 to 104 m² of heat-exchange surface area. Research and pilot units are also available with working volumes of 8 to 60 L.

Thin-film dryers gently process liquids, slurries and pastes

GIG Karasek

The thin-film drying technology from this company can be used for continuous drying of suspensions, municipal sludge, slurries, pastes, wet solids, filter cakes and chemical products. It is also suitable for heat-sensitive products, such as polymers, foods and pharmaceuticals. A thin-film dryer is a special type of wiped-film evaporator. The product to be dried is distributed over the circumference of the heating surface to form a downward-flowing thin film of liquid that is stirred by a specially shaped rotor system to create optimal turbulence. These dryers can produce dry powder from a liquid feed. They can be used either alone, or as a pre- or post-dryer combined with other equipment. Horizontal thin-film dryers are ideal for drying slurries and pastes, while their vertical counterparts are preferred for continuous drying of liquids to wet solids in a single step. Both types feature short residence times, low holdup, self-cleaning characteristics and low-energy consumption. Closed-system operation allows toxic and dangerous products, such as solvents, to be handled safely. Hall 6, Stand 328 — GIG Karasek GmbH, Gloggnitz, Austria
