Did you know that we have registered a new property right?
The ENTEX system is enriched by a further element – ERMO (degassing reaction module) is a world innovation that further enhances the efficiency and versatility of the ENTEX planetary roller extruder.
This latest addition to the modular system of ENTEX offers a significantly increased process chamber volume in comparison to the conventional cylinder assembly of the respective series.
It has been developed specifically for degassing applications. Here, free large-scale process surfaces and generously dimensioned flow cross-sections are decisive. ERMO maximizes these aspects without significantly changing the size of the extruder.
But the advantages of ERMO can also be used for the addition of fillers with particularly low bulk density – also here, the largest possible free cross sections are needed for the supply of such materials.
Another example of application are processes in the field of reactive extrusion. For their successful execution an extension of the dwell time or an enlargement of the reaction surface or of the volume are required.
Like all other components of the modular ENTEX system, several ERMOs can be used in series or at separate positions of a production line – in addition, there are various supplementary options such as side feeder, injection and degassing openings.

Laboratory roller extruders offer everything that the "big" planetary roller extruders can do, only in smaller, more compact sizes. Due to their versatility, they are mostly used as experimental extruders in laboratories or for the production of small quantities.
Some industrial production lines with an output of several tons per hour have originally started as laboratory roller extruders on a smaller scale.
For the development of new materials and production processes, ENTEX laboratory roller extruders provide possibilities that cannot be realized with other processing systems. Whether melting, mixing, tempering, cooling, compounding, dispersing, drying, chemically reacting, degassing or all of that at the same time in different zones of the process section, the modular design of ENTEX laboratory roller extruders offers a wide range of processing options, especially for mechanically and thermally sensitive materials. The art of modern process engineering lies in omissioning of process steps. Even very complicated reaction or mixing processes, e.g. for plastics, elastomers, foodstuffs or pharmaceutical and chemical products, can be realized with the multiple configuration variants of the modular ENTEX extruder system.
For the respective area of application, laboratory roller extruders are individually adapted to the customer's specific process requirements with regard to the used materials. The design size, process part length and equipment of the laboratory roller extruder are based on calculations and decades of experience. Special solutions are usually possible. When planning the extruder, in addition to the standard designs, special properties such as food suitability, acid resistance or resistance against abrasion or particularly high process temperatures, etc. can be realized for the parts in contact with the product.
The latest development in the field of laboratory roller extruders is the L-WE 30. This compact size from the modular ENTEX extruder system has been developed for the simulation of chemical and pharmaceutical compounding processes and for experimental extrusion trials.
With the push on a button, the height of the generously designed machine frame can be adapted to the local conditions. In order to achieve high efficiency and very short reaction times for the tempering, heat exchangers which can be supplied with primary energy, e.g. preheated water, can be integrated into the substructure. The throughput capacity is approx. 1 - 20 kg/h, depending on the material to be conveyed and the process parameters.
