Dry Cleaning – What We Do…

At all our dry cleaning plants, we have the most modern and up to date cleaning machines from the best brands. Our cleaning machines are all motor-driven washer/extractor/dryer that hold from 9 to 45 kg of clothes or fabrics in a rotating, perforated stainless-steel basket. The basket is mounted in a housing that includes motors, pumps, filters, still, recovery coils, storage tanks, fans, and a control panel. In all modern equipment, the washer and the dryer are in the same machine. Doing this makes it possible to recover nearly all of the chemicals used during cleaning, which is better for the environment and saves the dry cleaner money (A SAVING WE PASS ONTO YOU)!!

As the clothes rotate in the perforated basket, there is a constant flow of clean solvent from the pump and filter system. The solvent sprays into the basket and chamber constantly — not only immersing the clothes, but gently dropping and pounding them against baffles in the cylinder as well. The dirty solvent is pumped continuously through the filter and re-circulated free and clear of dirt that gets trapped in the filter.

As an example, one of our machines pump perc (the chemical we use for that machine) through the clothes at a rate of about 5,678 liters per hour. Perc is about 75 percent heavier than water. If a cycle lasts for eight minutes, the clothes would be doused during mechanical action with 757 liters of solvent. This is more than adequate to thoroughly clean the clothes.

The next cycle drains and rapidly spins the clothes to expel the solvent and then goes into a dry cycle by circulating warm air through the clothes. The remaining fumes and solvent are vaporized by warm air and then condensed over cooling coils. The distilled solvent is separated from any water (that may have remained in the clothes or system) and returned to the tank as distilled solvent. Since any moisture that may have condensed into water during the process floats on top of perc, it is relatively simple to separate it.

Cleaning plants using petroleum solvent rather than perc are exposed to a different set of circumstances and face some challenging considerations. The solvent is flammable, and therefore many fire-prevention steps must be taken for safety. The solvent is very slightly lighter than water and the two mix easily. There is also a need for higher temperatures to dry and deodorize the garments, which makes shrinkage and re-deposition of soil into the clothes more likely. These disadvantages are the reason why we currently uses perc almost exclusively.

DombaServ ensures the quality of cleaning, the degree of soil removal, the color brightness, the freshness, the odor and the softness by via the strict controls over our filter and solvent conditions and moisture. This is how we can maintain a high standard of Quality and Excellence in the whole process… coupled with Service, this is what DombaServ is all about…
