An overview of essential oil and vitamin case studies Phytochemicals are increasingly found in many food, chemical and agricultural items. Product and process optimization is becoming ever-more important in all of these industries, with a focus on quality, manufacturing efficiency, stability and formulation costs. Essential oils are volatile substances with a relatively high vapor pressure; they are susceptible to oxidation and light and may change or may even lose their properties when directly exposed to stressors. Like other sensitive, volatile, odor- or taste-intensive liquid active ingredients, they must therefore be protected from the environment or vice versa. For this protection and to simplify handling — as well as for better dosage and targeted release — these substances are therefore progressively offered and used in encapsulated and/or free-flowing forms. Various processes can be used to deliver products with a compact structure. During process development, the most suitable procedures and equipment

Glatt PHOS4green plant for fertilizer production with phosphorus from sewage sludge ash at Seraplant in Haldensleben, Saxony-Anhalt, Germany started up Residue-free production of ready-to-use fertilizer from phosphate-containing sewage sludge ash is now possible, thanks to plant manufacturer and process expert Glatt Ingenieurtechnik, and fertilizer specialist Seraplant. After a 20-month construction period, the first production plant for phosphate-containing mono and complex fertilizers made from recycled sewage sludge ash is now in operation. Seraplant operates the new plant at its headquarters in Haldensleben, Saxony-Anhalt, Germany. Glatt Ingenieurtechnik, a globally active plant engineering company, was responsible for the process development and construction. The official commissioning on May 31, 2021, was attended by Prof Dr Armin Willingmann, Saxony-Anhalt’s Minister for Economics, Science and Digitalization. Seraplant invested more than 20 million euros in the new production facility, with the support of the state of Saxony-Anhalt. As a result, more than 20 new jobs have been created in the southern

Fluidised bed and spouted bed processes offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients, the properties of which can be fine-tuned Fluidised bed and spouted bed processes by Glatt offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients, the properties of which can be fine-tuned using spray granulation, agglomeration, microencapsulation and coating. The consumer demand for fortified products is constantly growing and has been well received by end users. The form in which health-promoting probiotics, dietary fibres or antioxidants are consumed depends on both the preferences and everyday habits of the individual: some prefer sports drinks, protein bars or enriched iced tea, whereas others favour more direct dosage forms, such as effervescent tablets, sachets or capsules. However, although the manufacturing processes associated with these products present numerous challenges, a universal requirement is that functional ingredients must be stable during storage, precisely dosed, dissolve quickly or have a depot effect. Key

Plant protection products, be they herbicides or fungicides, must be dust-free, free-flowing, stable, safe to handle + provide good redispersibility properties. Product development usually focuses on the optimization of successful products: That means improved effectiveness and storage, safer handling and easier dosing. As well as these long-standing challenges, however, farmers and manufacturers of crop protection products are facing an increasingly fragmented market with regionally specific requirements. Due to globalisation and imbalances in the ecosystem, it is becoming increasingly necessary to control pests in a targeted manner and protect plants from previously unknown threats. Yet a growing market for organic farming means an increase in demand for biological or biodegradable crop protection agents which are obtained, for example, by fermentation processes. Industrial processing means these intermediate products are not temperature-stable and require gentle treatment at low temperatures. A further challenge is climate change: Cultivated areas in normally temperate climate regions are now exposed to weather events such

Sensitive raw materials, especially those that are volatile or of natural origin, require particularly gentle process conditions. Spray granulation, spray coating and (micro)encapsulation procedures have proven to be methods of choice, as they enable high yields, low temperatures and bespoke properties. When it comes to cosmetics, product development often focuses on proven, multifunctional ingredients. This is in addition to the ongoing demand for natural ingredients, as consumers increasingly look for effective cosmetic products that neither harm their health nor the environment. Glatt Ingenieurtechnik, the German expert in particle design, process development and plant engineering, offers unique particle processing solutions based on fluidised bed and spouted bed technologies for essential oils, collagens, active substances, stabilizers, enzymes, fragrances, aromas, vitamins and controlled release products, all of which can be optimally produced, protected and refined. Efficient fluidised and spouted bed processes Unique flow, mechanical and thermodynamic properties make fluid bed technology

Cleaning agents and detergents can be produced environmentally friendly and effective, using fluid bed and spouted bed technologies. Experts from Glatt Ingenieurtechnik explain. As a manufacturer of consumer goods, the detergent industry must respond to megatrends like no other. One of these drivers is sustainability; eco-friendly biosurfactants have been available since 2009 and, now, alternative complexing agents such as α-ADA or MGDA-Na3 can be produced from renewable raw materials and used to replace phosphates. According to the German Zukunftsinstitut (Future Institute), the neo-ecology megatrend is causing a reorientation of the values of global society, culture and politics and will have a defining impact on the 2020s [1]. Consumers and business partners alike are asking about transparent value creation and whether social aspects are being considered. As an example, seamless traceability has long been standard practice. Yet, the ongoing microplastics debate calls for a rethink when it comes to encapsulated fragrances or when the fibres of functional clothing have to be fished out of wastewater. Solutions for all these requirements can

Batch and continuous granulation and coating in one equipment for maximum process flexibility Weimar, August / 19 / 2014 – In a world of short-living products, flexibility of production equipment may give the leading edge on the market. For fluid bed processes, Glatt has designed and installed this flexibility in large scale. The AGT System can be equipped with an AGT insert for continuous spray granulation, a GF insert for continuous agglomeration and coating and a Vario insert for agglomeration and coating in batch mode. With this equipment even contract manu-facturers achieve the flexibility that they need to serve multiple cus-tomers. One unit with high capacities ensures low production cost. All inserts are shown at the Powtech 2014 in laboratory scale with the ProCell LabSystem. Fluid bed equipment can be used for spray granulation, agglomeration and coating. The process can be controlled and the product quality optimized by changing various parameters, including the design of the processing chamber. Laboratory equipment for feasibility trials typically

Laboratory fluid bed all-rounder now available in its 100% explosion pressure proof PRO version Glatt"s ProCell LabSystem – the most flexible laboratory fluid bed unit on the market – will be introduced in a fully explosion pressure proof PRO version at POWTECH 2013. Integrated in a mobile main unit, this modular lab all-rounder thus allows the use of all process options for batch and continuous fluid bed, spouted bed or rotor processes for a great variety of material systems such as powders entailing the risk of dust explosion up to hybrid mixtures. This compact and modular lab system allows you to process all dusts of the classes St-1 and St-2 as well as organic solvents. Users can benefit from considerable savings in safety reviews prior to trials or production while being prepared for the processing of future product generations. Using the proven concept of "avoiding ignition sources" an explosion is very unlikely. If an explosion occurs nevertheless, it will be enclosed within the explosion pressure proof ProCell LabSystemPRO and there

Processing of all St-1 and St-2 dusts and their hybrid mixtures The ProCell LabSystem – the most flexible fluid bed laboratory unit for granulation processes – is introduced in explosion pressure proof design at ACHEMA 2012. All St-1 and St-2 dusts, which means almost all common solid materials, can be processed in the lab unit. By this means the time needed for safety review prior to trials can be considerably reduced. In addition the equipment is safe for the future – even with products, not known today, tests will be possible. The proven concept of “avoiding ingnition sources” is still applied and makes explosions highliy unlikely. Yet, in case of an explosion, it is contained inside of the equipment. Solvents can also be processed, using additional equipment. In this case the solvents and explosive dust form hybrid mixtures. An explosion of these mixtures is also kept inside the pressure shock resistant ProCell LabSystem. When processing solvents not only explosion protection but also the environment and the cost

Product safety for food, biotechnology or similar applications Apart from the legal requirements in particular the EHEDG guidelines provide valuable directions and specifications for the hygienic and aseptic design of equipment, systems and complex production facilities. These have also to be considered for a hygienic conception of production processes for solid product forms. As a system provider of equipment for solids process engineering and an active member of the EHEDG-subgroup "dry material handling" Glatt Ingenieurtechnik Weimar makes its contribution to the development of guidelines in this field. Results from many years of experiences are considered in the relevant documents. To be able to produce under hygienic conditions a HACCP concept is developed together with the customer. Various requirements resulting from this concept have to be considered. Glatt Ingenieurtechnik has many years of experiences in this field. Several production facilities with specific hygienic and cleaning requirements have already been

Cleanability of fluid bed units in all scales Fluid bed and spouted bed units of Glatt are used to produce or improve granules and pellets. Spray granulation, agglomeration, coating and encapsulation are the most common processes. Glatt is supplying production size equipment with automatic cleaning systems since several years. Now it is possible to test the cleanability of the equipment in all scales. At Powtech 2011 Glatt will show a new feature of the largest mobile lab unit – a WIP system. The ProCell LabSystem is now equipped with cleaning nozzles in the filter plate and in the processing chamber, which clean the unit without the need to open it. Two different filter types can be used in the ProCell LabSystem – pleated cartridges and washable filter bags. The cartridges are only precleaned in the unit – the narrow places in the pleats must be cleaned manually. Still the WIP system makes sure the operator does not get in contact with the dry dust. The filter bags can be completely cleaned in the unit.

ProCell LabSystem for testing fluid bed and spouted bed processes „ProCell LabSystem“ is not only the new name of the largest mobile Glatt lab unit –but, all fluid bed and spouted bed processes can be tested in batch and continuous mode with only one equipment. The continuous operating mode is especially preferred for the liquid-only , spray granulation process. In batch mode this process can be tested only within narrow limitations. The “ProCell LabSystem” has evolved from the lab unit ProCell 5, which has been sold and rented to numerous customers. This customer experience and satisfaction was driven by the excellent operating reliability and process flexibility of the equipment. The “new” lab unit will now offer four different process systems.. Customers can select one, two, three or all four process options, based on the needs of the desired product or project, as necessary. Using the “ProCell-system”, spouted bed processes can be tested. The spouted bed technology is extending the possibilities to process

No dismantling of filter bags during wash cycle Wash in place – bag filters have also existed for several years. Glatt has frequently used them for the design of continuous fluid beds. Washing nozzles are installed in the clean and raw gas chamber at the top of the filter bags. During the wash cycle they flush the filter bags from the raw gas side and wash down all the dust on the surface. The quality of the washing process depends on the product. Our experience shows that in many applications the filters are clean for the next product. In order to improve the efficiency of the WIP step and to adjust the design of the specific granulator needs, we have now developed our own design of spray nozzles and filter bags. The filter has been installed in a GFG 250 and will soon be tested in full scale. Tests on our pilot unit were successful in 2008. After washing and rinsing the filter bags are dried in the fluid or spouted bed unit, and the next production campaign can start. This filter has a walk-in clean gas chamber

For continuous fluid bed and spouted bed equipment Fluid bed and spouted equipment requires additional space to service the filter on top of the already tall equipment. Up to 2.5 meters are required above the fluid bed contraption in order to exchange 6 m long filter bags. Glatt has now integrated horizontal filters into the fluid bed. The height of the equipment is decreased by putting the clean gas chamber to the side, resulting in no space being required above the fluid bed unit. Doors on the side of the clean gas chamber enable easy access to the filter elements. Exchanging of the filter elements is in actual fact easier from the side compared to the top. A further advantage is the possibility to design the room at the side of the clean gas chamber as a wash room with a solid floor and tight connection to the fluid bed unit. The dust-loaden filters are handled only within this room, contaminating no other parts of the plant with the filter dust. Having removed the filter plates the complete fluid bed unit can

The Austrian plant engineering and construction company AMMAG is specialised on spray granulation / coating and bulk material handling (conveying, silos, big bags, dosing and weighing). Own test plants in lab and pilot scale are used to test all process steps and to develop new products together with the customers. Toll manufacturing of these joint developments is possible, too. AMMAG has developed and constructed a novel laborscale spraygranulator A-WT 25. Air supply/-heating station and process-modul are designed in sparate units. Favorable design and a well elaborated plant concept, makes the A-WT 25 multi-purpose and in conformity with ATEX. The granulator can be operated in top - or bottom spray mode with different positions for the nozzels. An up-to-date control- and visualization system and changeable granulation-baskets for different batch-sizes give additional advantages to the user. Thus, first feasibility studies and small productions in the field

granulating with optimised energy efficiency and pneumatic conveying with minimised attrition Price leadership is difficult to achieve in the western economies; therefore AMMAG focus on the fortification of its innovative strength on within its own 70 years of experiences and core-competencies in the fields of bulk materials handling and fluidised bed spraygranulation. Following this visionary approach, AMMAG is further extending its Technical Centre, already the most modern of its kind in Austria, and has developed a laboratory granulator for the testing of new processes in the fields of spray granulating, coating, agglomeration and for the development of new products in close cooperation with clients. The second expansion of the pilot plant regards the business field: pneumatic conveying systems: a 40 m test line for pneumatic dense phase conveying and one for leanphase conveying in vacuum and pressure mode have been installed. AMMAG provides its research-infrastructure and its plant engineering competence both to foodstuffs and chemical industry leaders
