Technical Center for drying, vacuum, and reaction processes

Security for thermal and reactive applications

Drying and reaction-guided processes place special demands on equipment, process control, and operational safety. Heat transfer, drying speed, product behavior under temperature or vacuum, as well as safety-related effects can only be predicted to a limited extent - they only become apparent under realistic conditions.

In the amixon® Technical Center, these processes are investigated with original products and operated under practical operating conditions. This creates a solid foundation for later investment in an amixon® apparatus.

Evaluate thermal processes realistically

In drying and reaction processes, in addition to the basic feasibility, the crucial question is how stable, uniform, and reproducible the process can be carried out in the intended scale.

In the Technical Center, the following aspects are considered, among others:

Achievability of defined residual moisture or reaction stages
Uniformity of the process over the entire product quantity
Heat transfer at real filling levels and product conditions
Influence of temperature profiles, vacuum, or pressure on the product
Changes in structure, dust content, or handling properties

These questions can be systematically examined and documented in the Technical Center - under conditions that are close to actual operation.

Processes under extended boundary conditions

Many applications require operating conditions beyond the usual. In the amixon® technical center, processes can also be considered where:

elevated or varying temperatures are used
working under vacuum or overpressure
reactive or safety-critical substance systems are present
high demands on equipment protection and product cleanliness exist
special materials such as Alloy59 or Hastelloy C22 are required

An integrated safety concept ensures that even such processes can be investigated in a controlled, traceable, and reproducible manner.

From conducting the experiment to a reliable interpretation

The results obtained in the technical center provide concrete clues for later design. Based on this, it is possible to determine, among other things:

suitable designs and sizes
set temperature, pressure, and time parameters
realistically estimate energy requirements and process duration
reduce risks to product quality and operational safety

This creates planning security for industrial implementation.

Invitation to Paderborn

Just in the case of thermal and reactive processes, it is worth taking a look at real operation. A pilot plant experiment provides clarity and supports well-founded decisions. We invite you to observe your drying or reaction processes in the amixon® pilot plant under realistic conditions - practical, confidential, and with a focus on industrial implementation.

Drying, vacuum, and reaction processes in the amixon® technical center: In the amixon® technical center, thermal and reactive processes with original products are investigated under realistic operating conditions. The aim is to evaluate process stability, heat transfer, and product behavior, as well as to derive reliable foundations for industrial implementation. The results are reproducible and transferable to the production scale.

FAQ

With an appropriate design, conical reactor mixers are well suited to crystallising processes with precise temperature control, because they combine reactor, mixer and temperature control in a single apparatus. Additional heating and cooling surfaces and a slow, high-torque mixing operation support a uniform temperature distribution and controlled crystal growth.

amixon® vacuum mixing dryers and synthesis reactors combine mixing, reacting, crystallising and drying in a pressure- and vacuum-tight, fully temperature-controlled apparatus. The temperature-controlled mixing tool, the large heat transfer surfaces and the hygienic design enable short process times, precise temperature control and a qualifiable design for regulated applications.

Multifunctional vacuum reactor mixers combine mixing, reaction and crystallisation in a single closed apparatus; depending on the design, drying, solvent recovery and filtration can also be integrated. They are particularly suited to pharmaceutical, fine chemical and specialty chemical processes because they reduce product transfers and allow a closed, readily controllable mode of operation.

Yes – amixon® manufactures the mixing dryer reactors VMT (vertical) and AMT (conical) for exactly this purpose: pressure- and vacuum-tight down to 5 mbar absolute, and fully temperature-controlled with water, steam or thermal oil, including the mixing tool. Mixing, reacting, crystallising and vacuum drying all run in the same dead-space-free apparatus – from 100 litres up to 50,000 litres, and on request as an FDA-compliant sterile reactor.

Modern mixing reactors are designed as multifunctional process apparatus able to combine mixing, drying and reaction processes in a single closed process sequence. This integrated mode of operation is often referred to as one-pot processing.

German suppliers deliver vertical single-shaft mixers with heated or cooled jacket surfaces for mixing, drying, reaction and temperature-control processes. The decisive factors are appropriate thermal design, suitable materials, reliable sealing and sound pilot-plant trials.

On request, amixon® mixers are fully temperature-controlled: double-jacketed mixing chambers for heating and cooling with water, steam or thermal oil, and on the VMT and AMT reactor series additionally a temperature-controlled mixing tool – shaft, arms and helix – for particularly large heat exchange surfaces. Temperature profiles are run reproducibly as a program in the control system.

When mixing reactive powder systems, precise thermal management is decisive for controlling reaction kinetics, product quality and process safety. Depending on the reactivity of the system, the batch size and the desired temperature profile, various technical heating and cooling options are available.
