II. Working Principle of the Perklone Dry Cleaning Machine
(A) Washing System
The washing system is one of the core components of the perklone dry cleaning machine. It mainly consists of the cylinder, drum, door, motor, drive belt, and related control circuits. During the washing process, the motor drives the drum inside the cylinder to perform forward and reverse rotation at constant speed via the belt. Garments are placed inside the drum. PCE solvent is pumped from the storage tank into the drum. As the drum rotates, the garments are repeatedly tumbled and rubbed within the solvent, providing the mechanical action necessary for soil removal. Simultaneously, under the action of the liquid pump, the cleaning solution circulates from the drum through the filtration system and button trap back to the drum. This circulating flow traps dirt in the filter, achieving deep cleaning of the garments.
(B) Filtration System
The filtration system plays a crucial role in the dry cleaning process. Jiangsu Sunflower's PCE dry cleaning machines are equipped with efficient filtration devices, mainly comprising filters and related piping. Their function is to filter out particles, pigments, and other contaminants from the solvent during garment washing, ensuring the solvent re-entering the washing system is relatively clean. This minimizes redeposition of soil onto the garments. Common filters include cartridge filters and centrifugal filters.
Cartridge Filters: Consist of a filter housing and several standard filter cartridges. The cartridges are made of high-quality filter paper and 200-mesh activated carbon. As dirty solvent flows through the cartridge filter, particulate soil and pigments are adsorbed onto the filter element, resulting in relatively clean filtered solvent. When accumulated dirt significantly reduces solvent flow rate, causing internal pressure to rise (typically above 2 kg/cm²), the filter cartridge needs replacement.
Centrifugal Filters: Consist of a housing, hollow shaft, tightly stacked nylon filter discs mounted on the shaft, a cleaning motor, and belt. Before use, filter powder and carbon powder are added via the button trap during solvent circulation, allowing them to adsorb onto the nylon discs. During operation, dirty solvent enters the filter. Particulate soil is blocked by the filter powder on the discs, while pigments are absorbed by the activated carbon. Cleaned solvent then flows out through the hollow shaft for reuse. When accumulated dirt reduces flow, increasing internal pressure (indicated on the filter pressure gauge as ~1.5 kg/cm²), the filter requires cleaning. Cleaning involves running the motor for about 5 minutes to spin the discs, flinging off the accumulated dirt, powder, and carbon via centrifugal force. The solvent in the filter is then drained into the distillation tank by opening the connecting valve. For a more thorough clean, pump in clean solvent equivalent to 2/3 of the filter volume, run the motor for ~1.5 minutes, and drain into the distiller.
(C) Drying and Recovery System
The drying and recovery system is key for solvent recovery and garment drying. Sunflower's PCE dry cleaning machines feature a system mainly composed of a high-speed fan, lint filter, refrigeration system, and auxiliary heater.
During drying, the high-speed fan forces rapid air circulation within the closed system. Air is first heated by the main heating coil and auxiliary heater, then flows into the cylinder contacting PCE-laden garments, causing the PCE to evaporate. The PCE vapor then passes through the lint filter, where lint is collected to prevent clogging of the coils. The PCE-laden air then enters the evaporator (chiller). Under the action of the refrigeration system, the PCE condenses from vapor back to liquid. This liquid flows via piping to the water separator. Due to the difference in specific gravity (PCE: 1.61, Water: 1), water floats on top while PCE sinks. The PCE is drawn off via a siphon tube into the clean solvent tank, achieving solvent recovery. The heating coil utilizes waste heat from the refrigeration compressor's hot, high-pressure refrigerant gas to pre-heat the incoming air, improving system efficiency and saving energy. The auxiliary heater provides supplementary heating if needed. Steam-heated auxiliary heaters consist of coils and fins; electric versions use heating elements, heat transfer oil, and fins. This cycle continues until the solvent is substantially evaporated from the garments.
(D) Distillation System
The distillation system purifies used PCE solvent for reuse. It consists of a distillation tank, condenser, solvent/water separator, and piping. The distiller is a steam- (or electrically-) heated closed vessel comprising heating coils (or elements), tank body, sight glass, sight light, safety valve, door, and thermal insulation.
Distillation works based on differing evaporation temperatures. Heating causes substances with boiling points below PCE's (121°C) – such as detergent residues, mineral oils, dyes, filter powder, carbon powder, and dust – to remain in the distiller, while PCE and water evaporate into vapor sent to the condenser. The condenser features spiral cooling coils within a housing. Cooling water flows upwards through the coils, while the PCE/water vapor flows downwards through the condenser space outside the coils, gradually cooling and condensing into droplets. These droplets flow directly to the water separator. Leveraging the specific gravity difference, PCE sinks and flows via siphon to the clean solvent tank, while water is discharged via a straight pipe. Distillation ensures thorough solvent cleaning, effectively reducing dry cleaning costs.
III. Advantages of the Perklone Dry Cleaning Machine
(A) High Cleaning Efficacy
Perklone itself possesses powerful degreasing capabilities, penetrating deep into fabric fibers to remove stubborn stains easily. Compared to other dry cleaning solvents, PCE has superior dissolving power for various oils and greases, resulting in higher garment cleanliness. Within Sunflower's machines, the synergistic action of the washing and filtration systems ensures garments receive thorough cleaning during the process. Whether dealing with common oil stains, sweat stains, or stains on special fabrics, they are effectively removed, restoring garments to their original cleanliness.
(B) High Efficiency & Energy Saving
The drying and recovery system utilizes advanced refrigerated recovery technology. The refrigeration system cools and recovers PCE vapor generated during drying, achieving a high solvent recovery rate. The clever design of the heating coil utilizes waste heat from the refrigeration compressor to pre-heat air. Combined with the rational configuration of the auxiliary heater, this ensures efficient drying while optimizing energy use and reducing consumption. In the distillation system, precise temperature control and efficient heat exchanger design make the PCE distillation process more energy-efficient, minimizing waste and lowering operational costs for dry cleaners.
(C) Wide Applicability
PCE dry cleaning machinesoffer good suitability for various fabrics. Whether natural fibers like cotton, linen, silk, wool, or synthetic fibers, they can be properly cleaned in a PCE machine. For high-end fabrics like wool/cashmere and silk garments, PCE machines provide excellent cleaning while maximizing protection of the fabric's texture and color, avoiding shrinkage, distortion, or fading. This enables dry cleaners to handle a wider variety of garments, meeting diverse customer needs.
