An object to be washed is contained in the processing drum 11 'in the processing tank 1 and is immersed in this organic solvent, and after the organic solvent is flowed to a predetermined height (high liquid level in the case of main cleaning), The processing drum 11 'is rotated in the circumferential direction. The article to be washed also rotates with the rotation of the processing drum 11 ', and the contaminants in the article to be washed move to the organic solvent while being repeatedly immersed in the organic solvent, whereby the article to be washed is washed. After washing for a certain period of time, the organic solvent in the treatment tank 1 is discharged to the button trap 3, filtered to remove impurities such as fibers and buttons, and sent to the distiller 6 via the pump 5, where The generated vapor is liquefied by the condenser 7, water is further removed by the water separator 8, and is collected in the rinse tank 4 as a purified organic solvent for reuse.

Rinsing of the object to be washed is performed with an organic solvent in the rinse tank 4 which is not mixed with the detergent, and in this case also, the organic solvent is supplied into the processing tank 1 via the pump 5,
Rotate in the same manner as above to remove contaminants and detergent remaining in the object to be washed. Then, the organic solvent in the processing tank 1 is discharged to the button trap 3 and filtered, and impurities such as fibers and buttons are removed and collected in the wash tank 2. When the discharge of the organic solvent is completed, the processing drum 11 ′ is rotated at a high speed, and the organic solvent that has penetrated into the object to be washed is shaken off by a strong centrifugal force and discharged, and the wash tank 2 is passed through the button trap 3. Will be collected. The liquid removal operation is usually performed even after the main washing step. Next, high-speed hot air is sent into the processing tank 1 and blows into the rotating processing drum 11 '. The exhaust gas containing the solvent gas is sucked into the duct, and the solvent gas therein is condensed and recovered by a condenser in the duct (not shown), and the air is reheated and supplied to the processing tank 1 as air for drying. Use in circulation.

Reference numeral 11 shown in FIG. 7 is the processing drum 1 shown in FIG.
It is an alternative to 1'and is a processing drum which is concentrically provided inside a cylindrical processing tank 1. The processing drum 11 has an annular chamber 11e surrounded by a front wall 11b and a rear wall 11d ',

Further, the receiving members 27 are provided so as to face outward from the outer periphery of the support member 23 through the elongated holes 22a.

This molded product supporting device 21 is provided with a spring 2
It is extended by the action of 5, and by its pressure, it is bulged and supported by the front wall 11d and the rear wall 11d 'of the processing drum 11. Further, the pressing force of the thrust member 22 and the supporting member 23 is influenced by the elasticity of the pressing members 24a and 24b at both ends in addition to the spring 25, and is strongly and stably supported, but the molded product 12 is molded. Since it is performed manually when the molded product supporting device 21 is held by the product supporting device 21 or when the molded product supporting device 21 is loaded on the processing drum 11, it is necessary to adjust the pressure to an appropriate level. In addition, the pressing members 24a and 24b at both ends
Serves to prevent the front wall 11d and the rear wall 11d 'of the processing drum 11 from slipping, and the material, shape and the like are selected each time in consideration of the pressing force. Also, the presser foot 2
6 and the receiving member 27 are for holding the molded product 12,
