RF Dryers for VULCANISING AND DRYING The one-stop solution provider for latex foam vulcanisation and drying A very successful and well established application of STALAM‘s RF technology is the vulcanisation and drying of foamed natural and synthetic polymers (mainly natural latex, also blended in various proportions with SBR, and hydrophilic polyurethane). Radio Frequency drying does not rely on heat transmission, so even thick, shaped and dense items (casted blocks, mattress cores, anatomic pillows, etc.) vulcanise and dry quickly with no surface overheating or yellowing effects; it is...

RF vulcanisation STALAM has developed specific Radio Frequency equipment to vulcanise natural latex and SBR foam either inside moulds (mattress cores and pillows) or as a continuous sheet (LPC). The RF vulcanisation equipment are much smaller (shorter) compared to the conventional carousels or tunnels working with steam having the same hourly throughput, and the energy consumption can be cut by 50% (this value can be adequately documented). Moulds are made of light and inexpensive composite materials that allow weight reduction of over 60% compared to traditional metal moulds: the reduced...

RF drying In the past 30 years STALAM has developed and supplied a large number of RF dryers featuring specific technical solutions for natural or synthetic latex products (mainly mattress cores, pillows, anatomic seats and continuous sheet) after vulcanising, washing and squeezing or centrifugal hydroextraction, highly hydrophilic polyurethane foam after wet casting for health-care and medical uses, and other highporosity polymeric substrates. Our RF equipment provides fast and uniform drying: about 20 minutes are sufficient to dry even thick and dense mattress cores below 1% residual...

Radio Frequency (RF) is a drying and thermal processing technology based on the dissipation of electromagnetic energy within the product. Unlike conventional techniques, where heat is transferred to the product through its surface from an external heat source by conduction, convection or irradiation, a Radio Frequency field generates heat directly inside the entire product mass - that is why the related mechanism is called "endogenous” or "volumetric”. The heat generation is instantaneous and allows a rapid, uniform and perfectly controlled process, thus delivering outstanding results in...
