Vacuum Mixer Dryer with Conical Floor Boasts Complete Self-Discharge

With the AMT series, amixon presents a new generation of vacuum mixer dryers. The main difference between the AMT style and previous models is their conical floor form. This floor offers the decisive advantage that complete and automatic self-discharging 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 a three-dimensional movement of the mixing-goods. The helical spring gathers the mixing materials at the periphery of the mixing chamber and transports them upwards. Once it reaches the top, the mixture flows downwards in the centre of the container. The mixing effect essentially takes place at the interfaces between the two macro-currents.

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 patented mixing tool is only fixed and driven at the top. The tanks are 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 dough. Cutting rotors can accelerate the mixing and drying process and at the same time carry out de-agglomeration; as a further option, the tanks can be provided with a heated inspection door without dead space.

amixon mixers and dryers are developed to fulfil the highest hygiene requirements. They can be used as sterile equipment and reactors in compliance with FDA regulations, EHEDG requirements and the 3a sanitary standards.

Each amixon vacuum mixer-dryer and reactor is individually adapted to the respective customer’s requirements and process parameters. The mixers and dryers as well as all components are manufactured exclusively in Germany. The processes within the drying procedure can be determined at the amixon test centres at Paderborn, Germany, Memphis, US, Osaka, Japan, Bangkok, Thailand or Satara, India, where all the relevant parameters are recorded in real time.
