amixon® is presenting a new generation of vacuum mixer dryers with its AMT series. Machines within the AMT series differ from previous models because of their conical floor form. This floor offers the decisive advantage that complete and automatic self-emptying is achieved with free-flowing material. A further benefit is that even mixing is also achieved in the cone. This is the result of a patented, helical ribbon mixing tool, which creates three-dimensional movement of the goods to be mixed. The goods move upwards at the periphery, while they are moved downwards again in the centre.
Not only the mixer itself, but also the helical ribbon, mixing arms and mixing shaft are completely heated. Drying is extremely fast, gentle and even. The tank is vacuum- and pressure proof, which means that pressure-dependent reactions can also be managed. For example, an inert carrier gas can be used for subsequent drying.
The AMT mixer dryer reactor is suitable for drying powders, suspensions, pastes and doughs. Cutting rotors can accelerate the mixing and drying process and at the same time carry out deagglomeration; as a further option, the tanks can be provided with a heated inspection door which does create dead space. As the mixing tool is only fixed and driven at the top, it is not necessary to extend the shaft right through the product.
Machines in the AMT series were developed to fulfil high hygiene requirements. They can be used as sterile equipment and reactors in compliance with FDA regulations. In addition, they fulfil EHEDG requirements and the 3a sanitary standards.
Based on a fundamental design in 23 sizes ranging from 100 to 40,000 litres of vessel content, each vacuum mixer dryer and reactor is adapted to the respective customer requirements and process parameters. The processes within the drying procedure can be determined with the technical centre test apparatus at our Paderborn works, where all the relevant parameters are recorded in real time.
