Fluidised bed Coating can be used when a solid must be coated with another substance to obtain different properties or a protective cover. Coating is always used when a solid must be coated with another substance to obtain different properties or a protective cover. Various micro-organisms (bacteria, yeast) have a positive, physiological influence. Often, they are very sensitive to environmental influences. Resistance to gastric acid can also be required. Coating with wax, shellac etc. protects the dried organism.

Agglomeration is the correct process when a powder is to be turned into an easily pourable and soluble product, for example in perborate production. Filter dust accumulating during perborate production cannot be reused and must be processed by dissolving. The fluidised bed agglomeration with a suitable binding agent creates a saleable product. In addition to experience and innovative strength, AMMAG also stands for long-term relationships with employees, suppliers and customers, which are based on values ​​such as trust, respect and honesty.

Fluidised bed spray granulation produces granules of the desired particle size and high chemical stability through targeted particle structure and temperature control. Granulating creates free-flowing solids, directly from the suspension / solution. Pesticides are often produced in the aqueous phase as a suspension. A dust-free product (application safety) must be created. Targeted grain structure results in granules in the desired grain size and optimal temperature control enables high chemical stability. Fluidized bed spray granulation has become firmly established as a drying process in recent years, because it can convert a solid-containing liquid into a dry product in a single process step. Advantages of spray granulation (1) the possibility of influencing the resulting particle size and bulk density (2) the extremely precise control of product temperature as well (3) the generally low process temperature contribute to this success. A characteristic of the process is that the liquid is sprayed onto its own particles, which are intensively mixed and dried in the fluidized bed. As a result of the spraying, the particles…

Due to their design, fluidised bed technology systems can be used very flexibly. Fluidised bed technology processes benefit from: * the intensive mixing of the original solids * the large available particle surface * the fine distribution of liquid droplets A fluidised bed consists of a bed of solid particles that are lifted by an upward flow of air and thereby converted into a liquid-like state, i.e. fluidised. By spraying a solid-bearing liquid with an average droplet size of 50 µm (1 liter of water = 15 billion droplets) onto the fluidised bed, granules or agglomerates can be produced. Further possible steps are coating or matrix encapsulation phases. After any subsequent drying or further thermal treatment, the finished product can easily be discharged from the system. Addition of liquid is carried out with a positive-displacement pump by spraying, using a two-substance nozzle. Compressed air is generally used for nebulization. The use of other gases (for example: steam, nitrogen) is possible. The filtered and heated supply air…

Thrust blenders are the most suitable for gentle mixing of products with broad particle size distribution. For a functional-drink-application a ribbon type blender with 3000 litres useful volume was built. The blender has a single shaft. The mixing tools are ribbons, which are arranged screw-like at two circumferences. The inner ribbon with the smaller diameter promotes the product from the centre outward and the outer ribbon again inward. Pushing the ribbons through the bulk product provides the mixing. For application in the foodstuffs industry an EHEDG compliant design is used. The materials of construction were carefully selected and high quality surfaces were realized; furthermore, bolted connections were avoided as far as possible. Special attention was paid to dead-space-free constructions at the discharge, where a metallic sealing was implemented. Since the blender is wet cleaned, it is provided with particularly large openings, which improve the accessibility…

with the new laborscale-granulator A-WT25 and the pneumatic dense phase conveying system TPA 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…
