Cooling Tower Packing Reduces Harmful Bacterial Growth


SaniPacking fills and drift eliminators for wet cooling towers prevent the growth of bacteria, including Legionella pneumophilia, as well as Pseudomonas aeruginosa, the most common species found in industrial cooling water biofilm. When they are properly maintained, the antimicrobial effect can last for three to five years. The tough, impact-resistant, pressure-stable fills and drift eliminators consist of polypropylene films that are sealed and welded together to form secure modules with a cross-fluted structure. The honeycomb-shaped modules can operate consistently at hot-water temperatures up to 80°C and can handle temperatures up to 90°C for short periods of time. The lightweight material does not contain arsenic or heavy metals, and it is resistant to corrosion, UV radiation, most chemicals, fouling, and fungal growth. The fills and drift eliminators are available in various designs, all meeting International Organization for Standardization ISO 22196 and ISO 846 standards for its antimicrobial and antifungal properties, respectively.

Scraped-Surface Heat Exchanger Improves Handling of Viscous Fluids


The R Series rotating scraped-surface heat exchanger can handle fluids with extremely high fouling potential in sanitary and industrial applications. It uses a rotary scraper-rod capable of reaching velocities of 300 rpm to deliver high levels of shear mixing, increase heat-transfer rates, and provide constant agitation to keep solid particles in suspension. The scraper rod features both a helical mixing spiral and a series of scraper blades. The exchanger’s design enables high-viscosity products to be pumped at lower pressure and using less energy. The gearbox design reduces noise and allows multiple tubes to be fitted inside a single shell from a single electrical drive, further increasing the available heat-transfer area within the same shell footprint. The sealing system allows individual tubes to be removed for servicing and replacement, easing cleaning and maintenance. Most of the product can be emptied from the exchanger without the need for any additional pumps or pressure systems, reducing capital and operating costs. It is available in two lengths (1 m and 2 m) and with one-, three-, or six-tube options, providing a range of surface areas between 0.35 m2 and 4.2 m2; for larger installations, multiple units can be combined in series. The exchanger can be mounted horizontally or vertically, and internal baffles within the tubes can overcome shellside flow limitations. The heat exchanger is suitable for a variety of uses in the food processing and cosmetic industries, including heating, cooling, pasteurization, crystallization, and evaporation.

Solids Handling

Solids Mixer Evenly Distributes Added Liquid


The Model 700-TH-140-SS rotary batch mixer has an integral spray line that uniformly distributes liquid being added to dry bulk solids. Liquid can be sprayed over a wide expanse of moving material to ensure a uniform batch. Proprietary mixing flights of the rotating drum tumble, turn, cut, and fold material, creating free space between particles, which recombine 288 times per minute. The mixer is equipped with a sliding intake chute which, together with twin doors on opposite sides of the mixing vessel, provide rapid access to the interior, intake spout, and seal area for cleaning, sanitizing, and visual inspection of all material-contact surfaces. In addition to blending, the flights direct material toward and through a stationary, pneumatically actuated plug-gate valve for total discharge, eliminating residual material that would otherwise be wasted or require manual removal prior to cleaning. The mixer has a total capacity of 271 ft3 (7.67 m3), and a batch capacity of 140 ft3 (3.96 m3). It is effective at blending batches from 100% of the rated capacity to as low as 5% without liquid addition, and to 33% with liquid addition. The rotating drum is supported by two oversized trunnion rings that ride on heavy-duty alloy roller assemblies, eliminating the need for an internal shaft, minimizing maintenance requirements, and providing a long system life. To contain dust, the machine has one seal at the inlet, which is mounted externally to allow rapid replacement. Constructed of sanitary stainless steel, the mixer is intended for dry bulk blending, with or without the addition of coatings, flavorings, vitamins, other food products, or active liquid ingredients.

Mill Handles a Wide Variety of Materials

The Model CGM 750 cone mill gently grinds fatty, heat-sensitive, sticky, moist, or fragile materials into uniformly sized particles at rates up to 35 ton/hr (32 m.t./hr). Vertical material flow and low-energy grinding action with short residence times produce tight particle size distributions from 125 μm to 250 μm, without the noise, dust, product build-up or heat generation associated with traditional mills. Designed for bulk pharmaceuticals, foods, and contamination-sensitive chemicals, the sanitary unit is suitable for wet and dry milling, preconditioning, and de-agglomerating of a wide range of bulk products. Bulk material is fed by gravity or by a vacuum conveying system into a central milling chamber. There, a rotating impeller accelerates the material centrifugally against and through apertures in a conical screen. The ground particles then fall into a receptacle below the milling chamber. A pneumatic, swing-down conical discharge chute with quick-release clamps allows easy lowering of the 250-lb (114-kg) cone housing and full access to the housing interior, beater, and perforated conical screen for cleaning and sanitizing. Conical screens with round, square, or raised-lip (resembling a cheese grater) perforations can be changed rapidly and are offered with apertures from 150 μm for fine/dry de-agglomeration up to 25 mm for wet granulation. Constructed of Type 304 or Type 316 stainless steel to sanitary or industrial standards, the mill is top-driven by a belt drive. Fully interlocked moving components with a time-delay function ensure operator safety. This model has a diameter of 29.5 in. (750 mm); smaller models are available for laboratory applications.
