Polymer production – complex technological process where certain preparation steps can be more important than main ones. Especially it deals with preliminary drying of hygroscopic polymer raw material which humidity causes total loss of mechanical characteristics of the end product. Though non- hygroscopic poor dried granules can also bring technologists unpleasant moments: defects of the surface of end products, degradation or total loss of estimated characteristics, quality degradation of the product, increase of defective products. So, application of high quality drying units Somos T/TF by Mann+Hummel ProTec GmbH is an integrant part of technological process in polymer processing.
Convenience for technologists
Innovational small-type drying unit SOMOS T/TF is convenient in service and can be applied in drying any kind of polymer material , the main principle – connect and work, the only thing technologist has to do is to set up required temperature on control board. Aggregate is perfectly suitable for continuously-running fabrication, at not very high discharge the optimum result on efficiency and power consumption is reached. German quality helps to work continuously for a long time and optimum cost makes it available for a wide range of manufacturers.
Easy servicing, ease of operation – two in one
Drying unit SOMOS T/TF can be easily applied at any production process, mostly at producing small and midrange parts, and also at laboratory tests where dried hygroscopic material has to be used.
Uninterrupted quality of the drying process and manufacturing process and also produced goods is provided by commercial adaptor RS232, which includes protocol and free software. With the help of this adapter data is transferred and processed to any unit of the machine. Microprocessor-based unit RS232 controls all the parameters and excludes errors.
Raw charging is possible both manually and also by means of automatic vacuum loader. After drying process granules remain dry for a long time as hopper is hermetical and technologists should not worry about humidity of material during sudden stop of the main machine.
Technical parameters
Small-type drying systems have charging hopper for 5 and 10 liters and discharge capacity from 600 to 4000 g/h and from 1300 to 8000 g/h respectively. Particularly in corresponding units homogeneousness of the drying process is achieved for the whole volume of raw material what is important during processing expensive polymer materials, and automatic air-flow controller ALAV controlling the flow of air provides balanced drying and electricity saving.
As compressed air is applied expanding in the aggregate under the action of atmospheric pressure without moving parts it is possible to reach the dew point up to – 25 °С, what is very important during cold snap in production area.
Maximum temperature of drying in aggregate is 160 °С.
Assembling
Drying aggregates can be installed both on the main production machine and close to it and also build into centralized systems of supply and handling of polymer material. The quantity of charging hoppers and their dimensions depend on time necessary for drying, type of material, required efficiency, other factors and is chosen individually case by case. Technical specialists of Mann+Hummel ProTec GmbH firm will help you to make necessary scoping calculations.
As a conclusion
In case at continuously-running fabrication not very high discharge capacity of material is required then small-type innovative drying aggregates Somos T/TF by Mann+Hummel ProTec GmbH are perfect technological solution effective from the point of view of material expenses for purchasing, assembling and service.
