Designing a Laundry Plant
A laundry plant is a commercial operation that processes large quantities of laundry. These plants typically handle work for several satellite pick-up locations, as well as large commercial uniform or towel contracts. They may also service a variety of other businesses, such as F&B, industrial, medical retail and dust control.
A plant’s design is determined by many factors, including the types of work to be processed, type of customers, available space, processing needs, future growth, hours of operation and local codes/restrictions. Then, the designer’s job is to design the facility that will accommodate those requirements while meeting the company’s budget and operational goals.
Laundry has a long and complex history. In rural areas, before the advent of a washing machine, clothing was soaked in a stream or spring and then washed by hand. In the 19th century, washing machines became more common. These agitated water in perforated tubs to remove dirt from the garments. They were usually manual, with hand-operated paddles moving around in a tub. Later, electric agitators replaced the hand-operated ones. 작업복세탁공장
Throughout the 19th century, a variety of hand-operated washing machines were developed. Some used a perforated double tub to spin out the water, while others agitated water by turning a handle. These were similar to the perforated tubs that were later developed into clothes dryers.
Other mechanized washing devices were portable rub boards, which were rubbed against a flat rock. The rocks, called beetling stones, were often set up near the water supply to facilitate rubbing. These are still found in some poor countries.
In Europe, villages that could afford it built wash-houses, also known as lavoirs. These were similar to the modern wash-house, except that they had two basins instead of one and a stone lip inclined towards the water against which clothes were beaten.
These wash-houses were a lot more comfortable than washing in a stream, and a little less labor-intensive. In addition, a wash-house often had a small kitchen and a bathroom.
Then, in the early 20th century, some manufacturers invented hand-operated agitators that were inserted into perforated double tubs. Some were a bit more sophisticated, with an electrically powered agitator.
Various methods were used to dry clothes, from hanging them on poles or clothes lines to spreading them out on clean grass or bushes. Some hung their clothes in a drying shed, or in the case of wool, they were dried on a rack that was hung over a fire.
Other methods of removing the dirt from clothes included beating them with a wooden implement, such as a washing paddle or battling stick, bat, beetle or club. The dirt was scrubbing off with these, and the results were usually much better than simply soaking them in a stream or spring. 수건세탁
Then, as mechanization advanced and water was used less to clean fabrics, a process called dry cleaning began. It uses a chemical solvent other than water. The chemical solvent is often tetrachloroethylene, commonly known as “perc.” This can be done to clean delicate fabrics that cannot be washed by a traditional machine. It can also obviate labor-intensive hand washing and reduce the amount of time it takes to clean clothes.
