An essential part of the microwave vacuum dryer manufacturing process is the cleaning of microwave vacuum dryer parts, but this is very particular and requires different cleaning methods according to the geometry and degree of dirtiness of the parts. Although the selection of cleaning methods for parts does not affect the subsequent drying process of the machine. The first fast and effective way is vacuum drying, which is one of the drying links of microwave vacuum drying equipment parts. There is also convection drying and air drying with hot air circulation for heating and cleaning of microwave vacuum drying equipment parts themselves.

Microwave vacuum drying equipment parts are usually cleaned after processing or grinding work, or after heat treatment. Cleaning methods can basically be divided into two categories: aqueous solution cleaning and solvent cleaning. Of course, there are also some special processes. The final selection of cleaning method depends on many factors. The most suitable cleaning method must be selected according to the material of the microwave vacuum drying equipment parts, the type of dirt (different types of oil, grease, emulsion, dust, etc.) or the geometry of the parts (surface structure, holes, undercuts, etc.). Subsequent drying of the cleaned microwave vacuum drying equipment parts is essential.

Because in the case of aqueous media, even the smallest residual moisture can cause corrosive damage to the microwave vacuum drying equipment, resulting in high subsequent costs. Undried solvents can lead to the decomposition of the workpiece. Convection drying is the simplest drying method. The components are heated to between 70 and 80°C during the cleaning process, causing the adhering moisture to evaporate.

Both methods are suitable for microwave vacuum drying parts with simple geometric shapes. Vacuum drying is effective and reliable, allowing complex parts to be dried quickly and can be used for cleaning microwave vacuum drying parts involving aqueous solutions and solvents. Circulating air drying is a flow of hot air over the microwave vacuum drying parts, causing the moisture to evaporate.
