The design of the hydrophilic cotton web dryer allows a reduction of the drying time of one hour for a batch of thirty kilos of wet product to 40% initial moisture leaving it with a final moisture of 7% to 10% in turn with the study and experimentation it was concluded that by varying the drying temperature it was possible to obtain reductions in drying time, the most important drying parameters are the cotton bed height and temperature. |
