Operation Considerations of the Dryer

 The dryer is a kind of washing machine, it is generally used to remove the moisture in clothing and other textiles after washing . Most of the dryer including a rotary drum, the inner cylinder is driven by a belt, and hot air is used to evaporate water in the periphery of the drum.

The dryer can be divided into the following kinds: rotary drum dryer, three backhaul dryer, three drum dryer, batch dryer, direct thermal dryer, clothes drying drying machine, powder dryer, stone professional bake dry machine, new dryer, used dryer, industrial dryer, tea dryer, herbal dryer, corn dryer, vegetable dehydration dryer, food dryer, chicken manure dryer drum type dryer, drum dryer, stone dryer, rotary dryer, flux drying machines, automatic dryers, oil dryer, electric heating and drying machine, energy saving dryer, clothing dryer, towel quilt dryer, computer intelligent dryer, steam dryer, gas dryer slime dryer, slag dryer, fly ash dryers, desulfurization gypsum dryer sawdust dryer, tunnel dryer, dehydration drying machine, fertilizer dryer, honeysuckle dryer.

Operation of machinery and equipment are an extremely important regular work, it should be in close coordination with extreme operating and overhaul, full-time personnel should be  arranged for duty check. Dryer drying equipment should also be the case. The notations of the dryer operation as following:
1. The drying characteristics of materials: drying curve , critical moisture content, equilibrium moisture content under dry conditions to be selected.
2. Physical and chemical properties of the materials: morphology, water content, water content, nature, crystal water, particle size, bulk density, viscosity, heat-sensitive, softening point, the phase transition point, thixotropic, toxic, corrosive, odor, flammable, explosive, electrostatic properties, permeability, agglomeration, crystal, or the particles are easily pulverized.
3. The influence of material value of the goods and the drying effect. For example : the impact on the product moisture, pollution, temperature, wear, powder and crushed,  the value of the goods and rehydration.
4. the dry yield requirements and long-term planning.
5. The top and bottom of the drying process , involving the methods of feeding, discharging materials.
6. user's  operating level and maintenance capabilities.
7. The available heat source (coal, fuel oil, electricity, gas, liquefied petroleum gas, natural gas).
8 .  the drying method of the material,or dry methods of the similar products.
9 . choose the proper dryer according to the local average annual temperature, humidity .
10. Whether the venue installation size have any special requirements or not.
11.  material recovery requirements fo the dryer machine.
12.  procurement funds , local labor, land, energy prices may be invested.
13. environmental requirements: limit of the dust emissions, noise, vibration, odor, volatile conditions.
