Hosokawa’s Pesticide Milling System Helps Contract Processor Grow

07 March 2017

Hosokawa Micron Ltd recently beat stiff competition to win the order for a fine milling system to suit the rigorous demands of UK based contract chemical processing company, Exwold Technology Ltd. With an exacting requirement for a pesticide formulation milling system able to achieve throughput rates of 900kg/hr and a particle top size limitation of 15 microns the customer awarded the contract to Hosokawa based on their technical expertise, project management capability and most appropriate equipment supply to meet the target requirements. ‘The customer specialises in formulation and processing for the Crop Protection and Speciality Chemicals markets, providing toll processing services on a worldwide basis. We were happy to support through extensive product trials carried out at the Hosokawa Alpine test centre to ensure correct mill selection and operating parameters to meet the customer’s needs,’ explained John Buck, Area Sales Manager, Hosokawa Micron Ltd. Hosokawa Micron supplied a 630 AFG Fluidised Bed Jet Mill with integral 315 ATP Classifier which is capable of producing the top size requirement with extremely tight particle size distribution. This configuration gives the customer highly efficient and accurate particle sizing across the high volume throughput. Product is fed to the mill by screw feeder via a double flap valve to ensure an accurate, modulated flow of material and maintaining the integrity of the 10 Bar containment. Once milled the product is collected in a filter. As standard within an agrochemical plant the stainless steel construction milling system is fully ATEX compliant and built to 10 Bar pressure resistant design. The crevice free design of the mill and integral classifier helps ensure full product evacuation whilst the WIP nozzles allow easy cleaning for contamination free production between batches.
John confirms, ‘When the system was installed a few months ago, Hosokawa Micron engineers provided installation assistance and full commissioning services. The system is now fully operational with expected throughput and particle distribution targets achieved.’ Kevin Martin, Managing Director, Exwold Technology Ltd. commented, ‘This new milling system is highly efficient and enables us to produce high volumes of powders to exacting particles size to meet the demands of new and existing customers. We have been extremely pleased with the service we have received from Hosokawa Micron and their sales and engineering teams. The ability to undertake pre-purchase tests ensured we were able to buy the right machine for the job.’  

Hosokawa Micron Ltd Joins the Space Race

31 January 2017

Engineers at Hosokawa Micron Ltd have literally taken their latest glove-box developments into another dimension as a result of the company’s recent collaboration with the European Space Agency. Working closely with scientists and engineers at the Universitat Autonoma de Barcelona, Hosokawa has developed a pilot plant habitat (Pilot Plant Compartment V) in the form of a high containment glovebox and gas loop system. The Compartment V glove-box has been designed, built and installed by Hosokawa Micron as the final piece of the jigsaw in the MELiSSA Pilot Plant to provide a habitat for the development and demonstration of regenerative closed loop life support systems, paving the way for deep space travel. The project also offers potential solutions for today’s global challenges such as waste recycling, water provision and food production in harsh environments.
The MELiSSA project (Micro-Ecological Life Support System Alternative) depends on biological processes and understanding of how these may be affected by reduced gravity and cosmic radiation. For cost and safety reasons the MELiSSA Pilot Plant is a ground based, closed loop support system with a ‘crew’ of rats. Later developments will involve humans, in preparation for future space missions.
The Glove-box system represents the crew compartment and allows regeneration of the habitat atmosphere (loaded with carbon dioxide exhaled by the animal crew) and control of an oxygen fraction set-point. Part of the habitat atmosphere is circulated through a photo-bioreactor, where photosynthesis converts carbon dioxide into oxygen. The experiments carried out rely on having a ‘gas tight’ environment and the entire system was designed to achieve a leak tightness of less than 0.03% volume per hour (equivalent to a pressure loss of 0.3mbar/hour).

One of the main design challenges was extending the stringent leak tightness requirement to the integrated recirculating gas loop system components whilst also satisfying the specified process performance. Key components integrated into the gas loop include:

·         3 stage safe-change HEPA filtration ·         Carbon filtration ·         Gas stream heating ·         Gas stream cooling & de-humidification with condensate collector ·         Atmospheric variation pressure compensating system ·         Gas tight recirculation blowers ·         Gas sampling manifolds & gas analyser   The gas loop and Glove-box are fitted with instrumentation for monitoring and control of environmental parameters such as pressure, flow, temperature, humidity etc. As this is a closed loop system without external ventilation, the internal pressure would suffer large variations due to changes in atmospheric pressure and temperature without the innovative design of a pressurised buffer tank which can remove or add gas to the system to compensate for these variations and hence maintain a constant internal system pressure. It is important to maintain the internal pressure at a low positive pressure to minimise leakage into or out of the system and to allow easy use of the glove-ports. The airlock transfer chamber has a dedicated HEPA filtered air recirculation system to avoid cross contamination and the mixing of internal and external atmospheres. The inside of the isolator and airlock is designed for easy cleaning and decontamination and is periodically disinfected using a Vaporised Hydrogen Peroxide (VHP) system. Another key aspect of the design was to comply with strict requirements for the comfort and welfare of the animals. This includes strict control of the internal temperature, humidity and lighting (each cage has its own dedicated fan and dimmable, soft lighting) as well as removing potentially harmful contaminants from the recirculating gas flow. ‘This has been a very exciting project with which to be involved,’ said Adam Harper, Projects Manager, Hosokawa Micron Ltd., ‘As engineers it has tested our design capability whilst highlighted the flexibility of our Glove-boxes and their uses and also given us a valuable and fascinating insight into the complexities of engineering for space exploration.’

The Rising Tide of Super Seaweed

31 January 2017

Tipped as one of the superfood trends of 2016, seaweed is packed with minerals, vitamins, fibre, omega 3 and protein, often being added to food as a nutrient boost. Claims that it can prevent colon cancer, control blood glucose level and aid digestion make it of significant dietary and health interest whilst sustainable farming and harvesting methods have led to seaweed’s recognition as a ‘futurefood’ as well as a superfood. The fibrous, wet and often sandy or gritty, seaweed is however difficult to process with costly and time consuming drying times. To reduce the drying process seaweed is often chopped to facilitate more rapid, less nutrient destructive drying processes. For many years processing experts Hosokawa Micron Ltd have offered processing solutions to alginate producers across the world. To meet the demands for milled, freshly harvested seaweed Hosokawa Micron Ltd has developed a two stage system comprising of a Prebreaker and Vertical Disintegrator. This low energy system offers uniform particle size reduction of wet or moist seaweeds for further processing, which offers higher levels of availability compared to conventional hammer mills. Once the friable materials have passed through the initial size reduction (Prebreaker) stage, they are transferred directly to the Hosokawa Micron Vertical Disintegrator to be further reduced to a uniform particle size.   Designed for the reduction of fine to coarse, wet, moist or dry materials, the Hosokawa Micron Vertical Disintegrator provides automatic and continuous separation of disintegration resistant materials with redirection through the system from the exclusive secondary discharge.   Uniform particle size is achieved as materials are subjected to repeated impact and attritional force from the high speed rotating hammers, and carried by centrifugal force through a perforated sizing screen. The vertical screen frees itself of product instantaneously during processing, which is ideal for products with a high moisture content.   Barry Walmsley, Product Manager, Hosokawa Micron Ltd says, ‘The sturdy system, can operate at 12- 20 t/h.  It is low noise and delivers product in a narrow particle size distribution, resulting in higher yields and less effluent. The Disintegrator is designed to withstand corrosion caused by the low pH often involved in the process and erosion caused by the natural inclusions which determines a predominant use of higher abrasion resistant materials of manufacture.’

Cool Performance New Micron Glacis GC Mill

31 January 2017

Hosokawa Micron Ltd announce the development of the high performance cooling type, mechanical mill, the Micron Glacis GC fine grinding mill. Suitable for fine grinding of heat sensitive products, the Micron Glacis GC is ideal for the high volume grinding of green tea which is popular both as a beverage and for use in confectioneries too. The fine grinding and low heat generation of the Micron Glacis GC produces a tea with good mouth feel, texture, taste and mellow flavour. The Glacis is able to achieve a high cooling efficiency (7.5 times more than the conventional mechanical mill) by running coolants through the outer liner and grinding rotor. The Glacis can ultra-fine grind low-melting point, heat-sensitive materials that we impossible with conventional units. The Micron Glacis GC offers the particle grinding size accuracy of a jet mill (10 - 20µm) but with a higher volume capacity but with a 50% lower energy consumption. Material is ground by strong impact and shear force generated at the space between the grinding rotor and the liner. Both the grinding rotor and the mill lining are specially designed with an effective cooling structure which alongside the reduced air volume required by the unit for cooling actively prevents product oxidation and therefore deterioration of the tea quality. The Glacis has a low air volume requirement relative to grinding power which means the additional auxiliary equipment such as the blower and bag filer can be scaled down, allowing for a compact installation.

Save Up To 80% Energy Costs With The Micron Pulvis Sub-Micron Mill

31 January 2017

Capable of producing finer particle sizes than a jet mill and with energy consumption typically eighty percent less than other mills, the Pulvis offers an efficient alternative to impact type mills, when it comes to ultra-fine milling. As a dry agitated bead mill type, the Pulvis offers size reduction without the need for an additional drying phase. In the dry process particles do not re-agglomerate but remain in a dry, free flowing state, saving further energy costs and time. The mill is located at the bottom of the machine and ground particles are conveyed by air, passing through the grinding chamber to the integrated classifier the operating speed of which determines the fineness of the end product. The classifier separates the required fine product from coarse particles. The coarse particles are returned to the grinding zone. With the option of ceramic, wear protected grinding and classifying parts the Micron Pulvis is suitable for milling ceramic materials, metal oxides, battery materials, minerals, glass, hydrogen absorbent alloys, magnetic materials, pigments and carbon etc. Designed for easy access, disassembly and cleaning the machine is well suited to multiple applications and frequent material changes. Available in a range of sizes from 0.75 kW grinding motor (1.00 kW classifying motor) to 70.0 kW grinding motor (30.0 kW classifying motor) the Pulvis is suitable for test purposes through to fully scaled up production size.  

Flexible Compact Isolators for Nimble Manufacturing and Research

31 January 2017

 ‘Nimble manufacturing is now one of the main factors driving purchases of Hosokawa Micron’s Flexible Compact Isolators (FCI),’ says Carl Emsley, Sales Manager at Hosokawa Micron Ltd. As manufacturers strive to meet rapidly changing customer demand, production agility and nimble response is vital and Hosokawa customers are confirming that their small footprint, plug and play, high containment isolators are just what they need. ‘The ability to quickly respond to changes in demand is increasingly being seen as the key to success in pharmaceutical, cosmetic, biotechnology and research markets. As companies strive to ‘stay ahead of the pack’ and get a lead on their competitors, our mobile, barrier containment, compact isolators are proving that they are definitely up to the task. They make it easy to have flexible containment exactly where and when it is needed. ’ With the ability to use one isolator unit for several different processes or to link individual units together to create a multi-process work pod, FCIs create a real flexibility and agility in manufacturing or research settings that is not easy to achieve with large or static isolators. Delivering high containment levels of 1µg/m³, Hosokawa FCIs can cope with a range of potentially hazardous products, protecting both personnel and products. With excellent all round visibility and a range of rigid, semi rigid or disposable canopy options which fit onto the stainless steel base unit, many customers see the benefit of ordering more than one canopy style, further increasing manufacturing flexibility. The plug and play mobility of FCIs means units can be wheeled to where they are needed. Relocation is quick and easy and allows maximum use of the resource. Based on traditional, Hosokawa Micron static isolator designs the FCI is both durable and economic and with shorter manufacturing lead times it offers an ideal solution, particularly for test type applications, start-up companies or those for whom handling of hazardous powders is infrequent or when investment in a dedicated, static isolator, is not appropriate. The Hosokawa FCI can be tailored to suit customer requirements including air handling systems, CIP system, filtration and rapid transfer ports, nitrogen inertion, flexible glove port configuration and hazardous area systems. Hosokawa Micron can also offer a range of processing and packing equipment specially engineered in miniature for use within the Hosokawa Micron FCI.

New Buggy Fill/Weigh Booth

31 January 2017

  Hosokawa Micron Ltd announce the launch of a new ‘twin, buggy filling and weighing, containment booth’, designed to handle safe, easy and accurate FIBC filling. Designed in co-operation with a leading detergent manufacturer, to meet the demands of the high volume product transfer of potentially sensitising powders, the containment system is uniquely configured for automated filling of FIBCs located on a wheeled buggy frame. The booth is connected to the customer’s HVAC system to generate a horizontal laminar airflow which captures airborne particulates generated in the filling operations. The contaminated air is then extracted through the combined booth plenum to a remote filtration system. Double opening doors at the front of each booth allow easy access for the manual loading of the FIBC buggy. As the buggy is pushed into position the FIBC lid is automatically lifted, eliminating the need for an operative to undertake this procedure by standing on a step ladder. Guide rails ensure accurate positioning beneath the downward sealing filling head. Once the buggy is in position (defined by a sensor) a mechanic clamp device holds the wheeled buggy in place. Doors are interlocked to prevent unauthorised entry whilst filling operation takes place. On disengagement and removal of the buggy from the filling and weighing system, the FIBC lid is closed. Accurate filling and weighing is controlled from outside the booth and once filled the FIBC buggy can be wheeled away with operatives protected from potentially sensitising or hazardous, residual airborne dusts. The booth incorporates a single rear, personnel door for safety and ease of all round access and maintenance. The booth is equipped with integrated weigh scale, internal lighting and integral dust monitoring system.

Hosokawa Micron Engineers Break Record  With Eleven Metre Wide Downflow Booth

25 January 2015

Hosokawa Micron Ltd has manufactured one of the widest Downflow Booths they have ever made. The 11m wide Downflow Booth was designed and manufactured using Hosokawa Micron’s modular Downflow Booth concept which delivers construction affordability alongside almost limitless size capability. Designed to meet the customer’s requirement for increased raw materials handling capacity, the 11m wide Booth encapsulates 8 IBC filling stations and was engineered to suit the layout and available factory space. The booth’s open fronted design uses no vertical supports offering unrestricted operator access into the booth and to the filling stations which makes for easy transfer of IBCs. Hosokawa Micron Ltd. commented, ‘By incorporating, into our modular build concept, a unique bracing system that supports and stabilises the full width of the booth,and prevents risk of twisting or bowing, we can meet requirements for larger, tailored, contained work spaces. A single booth rather than several smaller booths can also offer customers real economies of scale – in this instance, a single(rather than multiple) control panel(s) manages the operation: delivering a cost saving for the customer. ’ 

Downflow Booths  Protect Food Operatives from Airborne Dusts

25 January 2015

With a high incidence of workplace risk from respiratory sensitising dusts from grains, flour, egg protein, fish protein and ingredient additives, Hosokawa Micron Ltd, a leader in containment technology has responded to food industry demands for improved and safe levels of personnel and product protection and by developing a range of modular Downflow Booths. Capable of delivering Operator Exposure Levels of <1µg/m3 the booths also provide product protection from surrounding area contamination by creating a ‘clean processing zone’ minimizing cross contamination risk from other products or processes. The Hosokawa Downflow Booths have been designed to meet key demands for energy efficiency, low running cost and low operating noise. Their cost effective yet flexible modular design makes them suitable for a range of applications when it is necessary to undertake processing steps outside of a closed food processing machine, such as sampling, filling or packing operations. The low running costs of the booths can be attributed in part to the incorporation of highly effective and energy efficient motors and fans.
