There are many types of dryer ,when choose a dryer , it  must be paied attention to their  models , what is required of the material , so buy the dryer will meet the needs of their work , but also to increase productivity , Dryer Selection mainly pay attention to the following points:

 

1, the physical and chemical properties of materials - shape , moisture content, water nature , crystal water , particle size , bulk density, viscosity, heat-sensitive , softening point, the phase transition point , thixotropic , toxic , corrosive , odor, flammable , explosive , electrostatic , air permeability , aggregates of crystals or particles for crushing .

    

2 , the material to be dried drying characteristics - to be selected in the drying curve under dry conditions , the critical moisture content, equilibrium moisture content .

 

3 , dry production requirements and vision .

 

4 , the value of goods and materials drying effect on them.

 

If the product moisture, pollution , temperature, abrasion , chalking , grinding, water-based and other complex impact on the value of the goods .

 

5 , the recovery of materials requirements .

 

6 , the upper and lower order process material drying process. ( This relates to the dryer , nesting state method )

 

7 , the material past the drying method or dry method similar products.

 

8 , the available heat sources ( coal, fuel oil , electricity, gas, liquefied petroleum gas, natural gas )

 

9 , dryer installation site size , any special requirements .

 

10 , environmental requirements - for industrial dryer dust emissions , noise, vibration , odor, volatile matter ... etc. restrictions.

 

11 , the amount of money may be invested drying equipment procurement , local labor, land and energy prices.

 

12 , the user's level of operating personnel and maintenance capabilities.

 

13 , the local average annual temperature , humidity
