Generally speaking, the drying process of a dryer used for materials usually depends on the properties and drying characteristics of the materials. The first four elements should be checked with the dryer manufacturer.
Generally speaking, the drying process of a dryer used for materials usually depends on the properties and drying characteristics of the materials. Review the first four elements with the dryer manufacturer.
(1) Material shape
The shape of the material can be said to be the main factor considering demand. Wood, ceramic products and the shapes of flakes, fibers, particles, fine powders and other materials based on pastes and liquids are used industrially for drying materials. demand.
(2) Various physical properties of materials
The physical properties of the material include density, bulk density, particle size distribution, and bonding characteristics of hot melt materials. The materials used and certain types of dryers have a great influence. When the adhesion is severe, the drying process cannot be performed.
(3) The characteristics of the material in the drying process
Contains sensitivity to heat, and some materials deteriorate after thermal decomposition. In addition, the shrinkage of the material during the drying process will cause the molded product to crack or deform, resulting in a waste of product quality.
(4) The combined state of the material and water
It feels that the degree of difficulty of drying, the level of energy consumption and the length of time in the dryer, which have a lot to do with the choice. For example, for materials that are difficult to dry, it is important to give a longer time instead of strengthening external drying conditions.
