Established in 1978, STALAM is the world leader in the development, design and manufacture of equipment where capacitive electromagnetic fields at I.S.M. metric frequencies (RF fields) are exploited for a variety of thermal processing and drying applications on raw materials, intermediate and finished industrial products. Company Profile As a member of AEI (Italian Electronic and Electrotechnical Association) and of ACIMIT (the Association of Italian Manufacturers of Machinery for the Textile Industry) STALAM cooperates actively with prestigious universities and research institutes for the...

Radio Frequency dielectric heating 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. Water molecules are highly...

Loose stock can be loaded directly on the conveyor belt of the dryer or even inside permeable bags. The reduced losses of product, the uniformity of drying, the improved physical-mechanical characteristics of the fibres, and consequently the more efficient carding - combing - spinning operations, result in a higher yarn metric yield of up to 2%. In the RFA (Radio Frequency Assisted) series dryers, the RF treatment is combined with a conventional warm air circulation system. The STALAM RF and RFA model dryers allow savings in operating costs up to 10-15% compared to other standard Radio...

RF ECO+ series dryers STALAM's continuous investments aimed to improve the performance and sustainability of its products led to the development of the new RF ECO+ series dryers. These highly efficient machines are mostly dedicated to medium and large size dye-houses, to meet their high production capacity requirements with the most favourable productivity/foot-print and productivity/cost ratios. Having rated power values ranging from 125 kW to 180 kW, the state-of-the-art RF ECO+ dryers ensure savings in operating costs up to 20% compared to the previous generation RF dryers still...

Best for loose stock, tow/top slivers and yarns in hanks An original version of these dryers is the RFA/S series. Here, the principles of both the RFA and LTRF technologies are combined: the forced air flowing through the product and the accurate temperature control inside the drying tunnel allow us to set all parameters of the evaporation process. Both the product quality and the energy efficiency are improved, and savings in drying costs up to 35% in comparison with the standard RF technology are obtained. Several LTRF and RFA/S series dryers installed worldwide since the mid-nineties...

RFA/S COMBO Twin-Power series dryers it 1-11 ■ The RFA/S COMBO series dryers are the latest evolution of the RF and forced-air circulation combined drying equipment developed by STALAM in the early nineties. In these dryers, independent forced-air drying sections are added to the standard configuration of the RFA/S machines, thus obtaining a truly "twin-power” drying system where it is possible to control and dose independently each form of energy (electromagnetic and conventional) for different products or process requirements, by modulating them through the PLC. The unique modular design...

TCRF series dryers The TCRF (Thermo-Controlled Radio Frequency) model dryers represent the outcome of the researches carried out by STALAM in co-operation with Messrs. Loris Bellini as to the drying of yarn packages and tops in bobbin or bump form by means of a combination of RF energy and forced air circulation. They can surely be considered as the most sophisticated batch-type textile dryers available worldwide. In the TCRF dryers a passing-through, inverter-controlled air flow makes it possible to control the product's internal temperature as desired while the RF energy is applied. The...

RFA/HP dryer Best for yarn packages This revolutionary drying equipment, specifically designed for yarn packages, combines the RF technology with a forced air circulation system through the product in a conveyorised type dryer. It is the first time worldwide that a passing-through air flow can be obtained in yarn packages in a continuous throughput drying equipment. The air forced through the product is heated up to the desired temperature without using any external (additional) energy source by recovering the heat dissipated by the RF generator. Both the RF energy and the warm air forced...

RF/T dryer Dryers for stocking and tights Best for stocking and tights The RF/T series dryer can be considered the only industrial Radio Frequency drying equipment specifically designed for the tensionless drying -partial or complete - of woven or knitted fabrics. The drying process takes just a few seconds, even for very thick (heavy) fabrics, and occurs under low temperature conditions (40-60°C). The residual moisture content in the fabric is perfectly uniform and controlled by an in-line computerised system. The RF/T series dryer can be used not only as a stand-alone drying unit, but...

Dryers for other applications Technical data Considering that most non-electrically conductive (ie. dielectric) substrates containing water can be dried quickly, uniformly, efficiently and with optimal quality results by means Radio Frequency, over the years STALAM has developed and supplied specific drying equipment suitable to process a wide range of textile, technical-textile and related products. Some existing applications of STALAM Radio Frequency dryers include: Work frequency of RF generators • the drying of bleached hydrophilic cotton fibres for medical, sanitary and cosmetic use; •...
