Before Drying
After Drying
Bagasse, the fibrous material, is one of the main by-products of cane sugar manufacturing plant, which is obtained after the sugar juice is leached out of sugarcane. It has moisture content of around 48% to 51% as it leaves the milling process. Bagasse drying is a matter of keen interest to the sugar industry, due to its utilization as fuel in boilers. Bagasse has a Gross Calorific Value of 9456 KJ/kg at 50% moisture and 12386kJ/kg at 35% moisture content. This shows drying bagasse before firing in the boilers could save considerable amount of fuel. Drying of moist objects is a complicated process, which is described as reduction of product moisture to the required dryness values at a definite process. All units the product to reach the drying values at the definite process consist of heating and dehumidification, which is described as the drying system.
Bagasse refers to sugarcane granular waste left after crushing and pressing. There are 2 to 3 tons of bagasse to produce one ton of sucrose. Bagasse is rich in cellulose, and less lignin, so bagasse is great fiber material. Fresh bagasse is irregular loose particles, low density, poor combustion characteristics, inconvenient to transport, storage and use. After drying the density, durability, combustion characteristics of bagasse will be improved, and easier to transport and storage. The dry sugarcane residues is good biomass energy. The sugarcane bagasse is a biomass that has many benefits. The sugarcane bagasse utilized as raw material for bioethanol.
Bagasse drying can use boiler flue gas drying. Sugar plant boiler flue gas temperature is usually between 160 ~ 180 ℃, still has a great value of thermal energy. The hot air will be extracted from the boiler flue and sent into the dryer by induced draft fan. With the function of gravity and rotary drums, bagasse will be suspended in the drying unit and fully mixed with hot air, then a lot of water will be evaporated. The important conversion from high humidity to low humidity, from high viscosity to non-stick will be completed; Under the effect of material lifting system, material will be constantly thrown and raised in the drying unit to form a uniform material curtain and fill up the drying space, thus more adequately contact with hot air. It maximizes the utilization of heat, enhances evaporation intensity. The water vapor will discharge from the end of the first level drum. The secondary cylinder is counter flow plus vortex drying. Material movement trend reverse fresh hot air flow. The turbulence will greatly improve, while heat transfer will increase, the drying efficiency also improve, so as to accelerate water evaporation. Finally, under the action of special pusher plate, the material automatically enters the third-stage dryer. The third level drier is intersect flow plus reciprocating drying. Under the action of hot air and special plate, wet materials move slowly and dry time and again, dry materials move fast and firstly, while meeting drying requirements, automatically discharged. Fresh sugar cane bagasse moisture between 48% to 50%, after a special dryer for sugarcane, moisture content can be below 12%.
Grains and dregs are the surplus by-products produced in the production process of food or agricultural products processing, wine making and other industries, which are rich in material resources. According to the data statistics, the annual production of dregs in China is on the rise. If it is not handled in time, it is not only easy to ferment, rot, stink, breed mosquitoes, cause serious pollution to the environment, but also increase the production cost of enterprises. However, due to the rich organic matter, nitrogen, phosphorus, potassium and other mineral trace elements needed for crop production, as well as a large number of carbohydrates, crude protein, crude fat and crude fiber, it is very suitable for livestock feed.
The dregs dryer can quickly dry the materials with moisture content of about 80% to about 10%, greatly reducing the moisture content in the materials, reducing the volume of materials, and facilitating the subsequent transportation and storage. The materials dried by the dregs dryer can be further recycled, which can not only turn industrial waste into treasure, but also reduce environmental pollution, and improve the added value of dregs products
The structure design of the dregs dryer is reasonable, which is mainly composed of hot blast stove, feeding device, dryer body, discharging device, induced draft fan, dust removal equipment, power distribution cabinet, etc.
Its technological process: hot blast stove is the place to produce heat energy. The fuel is added into the hot blast stove to produce high-temperature heat medium through combustion, which provides continuous and stable heat for the main body of the dryer. Then, the feeding device (belt conveyor, seal scraper conveyor or screw conveyor) evenly and continuously sends the materials into the dryer. The heat exchange between the material and the high-temperature heat medium is carried out inside the cylinder, so that the moisture in the material is evaporated, and the material changes from high humidity and high viscosity to non humidity and non viscosity. The materials meeting the drying requirements are transported out through the discharging device for unified packaging and loading. The flue gas, dust and other gases generated in the drying process are transported to the dust removal equipment through the induced draft fan for purification, filtration and dust reduction, so as to achieve the gas emission standard. The whole drying production line is integrated to complete the drying of materials.
We have different hot air generating device for you. According to your Heat Source, no matter it is natural gas, bio-gas, coal, oil, bio-mass fuel or others, we match furnace, chamber, burner etc to be most suitable. What's more, the boiler flue gas can also be used as heat.

Scrubber
Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams.
The exhaust gases of combustion may contain substances considered harmful to the environment, and the scrubber may remove or neutralize those. A wet scrubber is used for cleaning air, fuel gas or other gases of various pollutants and dust particles. Wet scrubbing works via the contact of target compounds or particulate matter with the scrubbing solution. Solutions may simply be water (for dust) or solutions of reagents that specifically target certain compounds.
Cyclone Dust Collector
Centrifugal cyclone dust collector, the dust will be separated and recovered in the drying system, through the dry tail gas dust purification device of a cyclone dust collector, suitable for high dust concentration, large dust particles of exhaust gas dust removal operations, the dust collector has a simple structure, stable and reliable operation, long service life, and other characteristics.
Baghouse
A bag house, also known as a bag house filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air.
Most baghouses use long, cylindrical bags (or tubes) made of woven or felted fabric as a filter medium. For applications where there is relatively low dust loading and gas temperatures are 250 °F (121 °C) or less, pleated, non woven cartridges are sometimes used as filtering media instead of bags.
Bag houses are very efficient particulate collectors because of the dust cake formed on the surface of the bags. The fabric provides a surface on which dust collects through the following four mechanisms:
Inertial collection – Dust particles strike the fibers placed perpendicular to the gas-flow direction instead of changing direction with the gas stream.
Interception – Particles that do not cross the fluid streamlines come in contact with fibers because of the fiber size.
Brownian movement – Sub micrometre particles are diffused, increasing the probability of contact between the particles and collecting surfaces.
Electrostatic forces – The presence of an electrostatic charge on the particles and the filter can increase dust capture.
A combination of these mechanisms results in formation of the dust cake on the filter, which eventually increases the resistance to gas flow. The filter must be cleaned periodically.
