Dryers for industrial laundries

Stalam has developed a Radio Frequency dryer that allows to optimize the continuous washing-drying cycle of natural latex or polyurethane mattresses after washing and mechanical hydroextraction. The equipment is mostly dedicated to industrial laundries serving hospitals, barracks, rest homes, hotels etc… for their washing and sanitisation requirements. The process is quick and uniform (up to 10 mattresses per hour), speeding up delivery times to customers and ensuring a rapid pay-back period.

The Radio Frequency technology 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 wets 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.
