Dryer is widely used for drying and dehydration of materials and products in pharmaceutical, chemical, food, light industry, heavy industry and other industries. Work principle:

Work principle:

Drying

Drying refers to a process where wet materials (typically containing water) are heated to make liquid contained vaporize and get a dry solid product. This process involving phase change is also a separation process where heat and mass are transferred at the same time. Wet materials can be divided into heterogeneous systems containing solid and solution or gel homogeneous systems, as well as salts containing water of crystallization. As different materials have different moisture retention property, water contained sometimes spreads to the surface for evaporation, or sometimes vaporizes within the materials and then spreads to the surface.

Dryer 

Dryer is a kind of equipment used for drying. General requirements for a dryer: 1. can reach the required degree of drying and realize uniform drying; 2. fast drying; 3. high thermal efficiency; 4. low fluid resistance; 5. easy to operate and maintain, with simple ancillary equipment. Choose dryers according to material properties and the required degree of drying. Dryers can be classified as follows based on heating methods: 1. convection dryer, including air dryer, fluid bed dryer, spray dryer, rotary dryers, tray dryers, belt dryer, tunnel dryer, flow dryer, etc.; 2. conduction dryer, including tray vacuum dryer, rake vacuum dryer, cylinder dryer, disc dryer, drum dryer, indirect heating rotary dryer, freeze dryer, etc.; 3. radiation dryer, such as infrared dryers; 4. dielectric heating drier, such as microwave drier.。

Vacuum drying

It refers to a process where wet steam in materials is dried strongly in vacuum. It can significantly reduce heat loss taken away by the drying medium and is easy to collect valuable or harmful vapor emitted from the materials. Vacuum drying is suitable for drying heat-sensitive or explosive materials, and can be used to recover solvents in materials. Vacuum drying equipment has many types, including multi-layered dryer, rotary dryer, belt dryer, cone dryer, spray dryer and vacuum freeze dryer.

Spray dryer

It’s a kind of continuous pressure dryer and can be used to dry solution, suspension or slurry-like materials. In the cylindrical spray tower, materials become vaporous by the action of the atomizer and disperse in the hot stream. The materials contact with hot air through countercurrent flow, countercurrent flow or mixed flow, so that moisture evaporates quickly. Its main advantages: 1. fogdrop will be dried in a very short time, usually 5-30s. Although the temperature of the drying medium is very high, the materials will not be overheated. Therefore, it’s suitable for high heat-sensitive materials and easily decomposed materials; 2. dry materials of 30-50μm can be packaged directly as a finished product; 3. good mobility. However, its disadvantages are as follows: 1. low thermal efficiency, generally only 40 %-50 %; 2. the device size is large. The atomizer has three types: centrifugal, pressure and airflow.
