As the name suggests, a dryer is used to remove moisture from an object. Its main principle is to use the hot air blown out to evaporate the moisture in the object.
1、 Principle of dryer
As the name suggests, a dryer is used to remove moisture from an object. Its main principle is to use the hot air blown out to evaporate the moisture in the object. There are usually two types of dryers: convection drying and vacuum drying. The former refers to evaporating and drying the moisture on the surface of an object by blowing out hot air at room temperature; The latter is to place the object in a vacuum chamber and use the low-pressure environment inside the chamber to lower the boiling point of the substance, causing the surface moisture of the object to evaporate and dry.
2、 Precautions for dry objects
1. Avoid excessive drying
The drying time required for different items varies, and excessive drying may lead to a decrease in the quality of the items. For example, dried fruits, flowers, and other plant-based items usually take about 24-48 hours to dry, and excessive drying can lead to deformation and fading of color. Therefore, when using a dryer, it is important to pay attention to the drying time and stop the machine at the appropriate time.
2. Avoid excessively high drying temperatures
Excessive temperature can easily burn out items, such as organic materials. Once the temperature is too high, it can easily cause combustion or even explosion. Therefore, when using a dryer, it is important to control the drying temperature and avoid exceeding the limit that the item can withstand.
3. Clean the dryer
Drying machines can accumulate dust and dirt during use, and long-term failure to clean them can easily affect the drying effect. Therefore, after use, it is necessary to clean the filter, air outlet, and other parts of the dryer to ensure its normal operation and drying effect.
4. Ensure the quality of the items
When using a dryer, it is important to ensure the quality of the items to be dried. Do not dry items that have cracks, damage, or mold to prevent further damage to the quality of the items or affect the lifespan of the dryer.
