It is related to the method. In laundry washing / drying devices used in technology, the material is placed inside the drum. The laundry is dried with drying air that is heated by passing it through a heating source. The drying air absorbs the moisture from the wet laundry, and the absorbed moisture is then returned to the dryer's 10°C. condensed inside the body of the container and transferred to a storage tank easily accessible to the user. or it is sent to the wastewater drain with the help of a pump system. Drying process During this process, energy is expended for both the heating element and the movement of the drum. At this point, Correctly determining the laundry load and the moisture content in the laundry, at the end of drying to achieve the desired humidity level and to save energy while doing so 15 It is of great importance in this sense. In technology, drying devices have been developed to accurately determine the laundry load and humidity level. And methods exist.

Varying results can be obtained with wet laundry. Water retention depends on the type of textile. Because its capacity varies, it is intended to be dried in the same drum, but Laundry items with different water retention capacities will not have a homogeneous moisture level among themselves. The problem arises that it doesn't provide adequate moisture. This means that some laundry comes out of the dryer damp. This causes some of the laundry to dry excessively when it comes out. Therefore, the moisture in the laundry... By measuring the homogenized material, load sensing and drying become more effective. The need for devices and methods that enable this process continues. The aim of this invention is to handle wet laundry loads at a higher capacity compared to current technical applications.
