Abstract (en)

A method for washing and/or drying products (20) envisages that the products are washed in a machine (1) with a flammable solvent, then dried using hot air in a washing drum (2). The temperature (T2), and, therefore, the solvent concentration (C2) of the air/solvent mixture in the drum (2) are constantly regulated during the drying stage, on the basis of the actual values of the evaporation pressure (P1), measured inside the cooling circuit in the low pressure zone which constitutes the machine (1) condenser (5), and/or the temperature (T1) of the air or the air/solvent mixture, measured at the infeed (3) of the drum (2). When at least one of the above-mentioned actual values (T1, P1) is above the relative preset nominal value, product (20) drying is automatically interrupted. <IMAGE>
