Straw is a generic term for the stem and leaf (spike) of mature crops. Usually refers to the remainder of wheat, rice, corn, potato, rape, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds.More than half of the crop photosynthesis products exist in the straw, straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, is a multi-purpose renewable biological resources, straw is also a rough feed.
Straw is a low-carbon fuel, and sulfur content, ash content than the current large amount of coal is low, is a more "clean" fuel, in the effective sewage protection measures to develop straw power, will greatly improve the environmental quality, Environmental protection is very favorable. In rural areas to promote the implementation of straw power generation technology, saving non-renewable resources, ease the power supply and other aspects are of particular importance.
Rotary drum dryer is designed to dry Biomass Straw which contains high moisture.Heat is generate by hot air generator by Coal, gas, petrol,diesel, biomass fuel etc.Total system is automated & moisture in material is adjustable as per requirement in various sectors.Depending on raw material,moisture and required production we can suggest suitable model and an approximate cost of your system in a short time frame.And Continuous work can reduce the cost of your company.
Application
Specification
Schematic of structure
Working principle
The hot air and wet Biomass Straw were sent into the main drying unit. Then the wet Biomass Straw and hot air will be sent into first stage of drying equipment,There is a special broken device in the first stage drying equipment. In this broken device, the wet Biomass Straw will be broken into scattered and "boiling suspended" state. With the hot air, the scattered Biomass Straw will be keeping rolling, rotation and separation. So the wet and sticky and blocking phenomenon of Biomass Straw is solved. Thus the important transformation "high humid —→ not humid, high sticky —→ not sticky, high viscous to not viscous" is completed.
Water vapor produced in first stage drying process is automatically discharged at the end of first dryer. The scattered Biomass Straw are discharged into second dryer.The second dryer adopts reverse flowing and vortex drying technique, the drying efficiency is also intensified. At the same time, heat and mass transfer is strengthened, which leads to bound water extravasation and evaporation speed up. Water vapor is discharged at the end of the second dryer. Biomass Straw are automatically sent into the third dryer . The third dryer adopts interflow plus reciprocating drying technique,the wet Biomass Straw move slowly and reciprocating, while the dried ones move in advance and fast. Biomass Straw will be discharged automatically when they are dry enough as request.
Advantages
Special technology can take more energy-saving and efficient for you,and the main structure is consists of three different metal steel cylinder with different diameter, it can get a bigger evaporation area, and drying faster,letting the material make a full contact with the hot air;"Auto-Feeding Control device" can be regulated according to the moisture content of the material;"Negative pressure"working condition, clean work site and operating reliably.
