Radio Frequency Dryer
45 years designing and manufacturing state-of-the-art Radio Frequency drying and thermal processing equipment. 2600 machines in more than 70 countries.
1. Dryers For Yarn Packages and Tops/Bumps
The most practical and convenient way to dye yarns for weaving or knitting is to wind them in packages that can easily be loaded on suitable carriers and dyed in pressurized vessels of any size. Not surprisingly, yarn packages are the most common textile product dried in Stalam Radio Frequency equipment.
Over the years, Stalam has developed the widest and most advanced range of drying solutions capable to address all the specific needs of yarn package dyers and enabling them to achieve the best quality results with the minimum operating costs in all circumstances. Some of these solutions are also suitable to achieve the same outstanding quality and efficiency results in the drying of tops in bobbins or bumps.

Benefits:
| ✔ | Rapid and uniform drying. |
| ✔ | No discolouring, no yellowing, no hairiness, no strength loss. |
| ✔ | Instantaneous start/stop (no need for pre-heating / cooling). |
| ✔ | Low overall running cost. |
| ✔ | More softness, better touch, minimum conditioning time. |
| ✔ | Modular construction to meet every production requirement. |
2. Dryers or Loose Stock, Tow/Top Slivers and Yarns in Hanks
Textile fibers and yarns can be wet-processed (mainly bleached or dyed) in various ways and forms, according to convenience or to respond to specific requirements. Whatever the substrate, whatever the process, Stalam has developed the best drying solutions.

3. Vulcanisers And Dryer for Latex
Foam products are quite difficult to dry by means of conventional hot air systems due to several reasons: they are good thermal insulators, so heat conduction within the substrate is extremely slow; their physical-morphological structure make them little permeable to fluids, so air convection is also heavily hindered; for the same reason and due to their chemical nature, the water vapour migration from the centre towards the surface of the product is intrinsically slow; in many cases the items produced are thick, bulky, shaped, dense, etc.
The Radio Frequency technology overcomes all these inconveniences because: it does not rely on heat transmission, so even thick, shaped and dense items (casted blocks, mattress cores, anatomic pillows, etc.) dry quickly with no surface overheating or yellowing effects; it is selective towards water, so even that contained in the core absorbs the RF energy instantly and migrates quickly towards the surface, leaving no wet spots anywhere in the product; the energy delivered to (absorbed by) the product can be adjusted as required, thus enabling to control accurately both the evaporation rate and the residual moisture content.
Similar considerations also apply to vulcanisation, so that the use of Radio Frequency fields, in combination or as a replacement of steam heating, makes the process much faster, thus reducing proportionally the space required to achieve a certain production capacity, and considerably more efficient, leading to energy savings of over 50%.
