A dry cleaning machine for articles such as garments and the like, comprising:
- a rotary drum for containing the articles;
- means for feeding a solvent into the drum;
- means for draining a solvent out of the drum;
- a closed circuit for circulating air for drying the articles inside the drum, comprising at least one air movement fan, means for driving the fan, a heating device for heating the air to be fed into the drum, an air cooling device for condensing the solvent contained in the air flowing out of the drum;
- characterized in that it comprises:
- a control unit, connected to the means for driving the fan and programmed to regulate the rotation speed of the fan according to a given time setting corresponding to given values of solvent concentration in the drying air.
A dry cleaning method for articles such as garments and the like, comprising the following steps:
- feeding a solvent into a drum for containing articles;
- rotating the drum in order to distribute the solvent on the articles;
- causing a drying air flow to circulate along a closed circuit the drum forms part of, in order to dry the solvent from the articles;
- heating the air circulating in the closed circuit upstream of the drum and cooling the same air downstream of the drum;
- the method being characterized in that it further comprises the following step:
- varying the speed of air circulation along the closed circuit during the step of circulating a flow of drying air along the closed circuit.
