during the wash cycle, the chamber is filled approximately one-third full of solvent and begins to rotate, agitating the clothing. the solvent temperature is maintained at 30 degrees celsius (86 degrees fahrenheit), as a higher temperature may damage it. during the wash cycle, the solvent in the chamber is filtered and then fed back into the chamber. this is known as the cycle and is continued for the wash duration. the solvent is then removed and sent to a distillation unit that has both a boiler and condenser. the condensed solvent is fed into a separator unit where any remaining water is separated from the solvent and then fed into the 'clean solvent' tank. the ideal flow rate is one gallon of solvent per pound of garments (roughly 8 litres of solvent per kilogram of clothing) per minute, depending on the size of the machine.
