Made from biomass waste biomass energy particle or waste derived fuel (RDF - 5) as a renewable energy is becoming more and more common.
Appropriate particles provide resources recovery and production of biofuels core equipment and solutions.
Biomass granule raw materials:
Agricultural waste: crops straw, rice husk, cotton stalk, coffee shell, alfalfa, coconut, palm shell of straw, bagasse, etc.
Forestry waste: sawmill residue, branches, bark, leaves, etc.
Solid waste, waste paper, plastic, cardboard, etc.
High quality of biomass particles moisture and ash content is low, at the same time can produce higher heating value.
Receiving of raw materials
Raw materials have different shapes.Need a sorting machine to separate inorganic materials.
Magnetic separation machine
To avoid impact crushing process, so I need magnetic separator to separate magnetic metal.
Before crushing
Need before crushing in order to decrease the size of materials.
dry
Material moisture content is higher, usually drying process will be necessary to reduce the moisture.
Air classification
This process is the last process to remove impurities.
After crushing
This step is a final crushing material before entering the granulation system process.
granulation
Granulating from the beginning of the preset quality, to steam hydration, further before and after entering the granulating chamber to form particles of raw materials for cooking.
cooling
Use the surrounding air cooling hot particles from the granulator;Need a thorough cooling in order to prevent the condensed water bead particles within the packaging.
packaging
Packaging can provide protection for particles, also facilitate handling and transportation to the customer.
Biomass energy particle manufacturing program
Appropriate big pelleting machine with high productivity, low energy consumption production high quality particles.Through the special mould and roll (pressure) roll design, the production cost can be reduced to a minimum.The design of the roller combination easy to adjust the gap between the roller and die.For different raw materials, proper clearance will help rolling roller work and achieve maximum yield (pressure).The size of the particles by net die aperture control, network mode of compression ratio on grain quality and yield is crucial.
After granulation process of sawdust particles is hot.cooling機利用周遭空氣減少水分並將顆粒的溫度降低至室溫的 ±5 °C，冷卻可延長木屑顆粒的保質期。
After the production of particles will be through a sieve to remove any irregular particles and dust.
In accordance with the weighing sensor and bagging machine set, the weight of the sawdust particles bagging, and seal after storage.After packing finished product can be by truck or container bags.
Appropriate process design and equipment characteristics and advantages
Appropriate big believes that conform to the purpose of design strategy.We realized that our customers facing the rising raw material costs, rising energy costs and overhead costs, however, in the face of these challenges, we still hope to the competitive market with high quality products.Our design concept is constantly improve and improve the technology and equipment, the maximum success for our customers.The following describes some of the features and advantages by this idea.
All the equipment can design is based on the concept of continuous production, and make the outage time to minimize the gap refueling, appropriate product's mission, is after the installation, in addition to routine maintenance and consumption parts replacement need downtime, all of the devices can be production all year round.
Two aspects are affecting the recipe: use effect and the efficiency of the machine.For example, choosing the appropriate source of wood is very important.Is not appropriate wood source can reduce the steam mixed with degree and cause the clogging in granulator.Fat and moisture content in the production of crusher plays an integral role
Appropriate big dual-axis mixer each axis of independent driven design reduces the power consumption and noise.When the blade reversal chamber can be completely empty.Atomizing nozzle to further improve the overall efficiency of steam and water conditioning efficiency, subsequent conditioning system using steam jacketed clamp (or hot) insulation for conditioning the uniform mixture almost no water;Preset quality deficiency can lead to crack of particle surface and generate dust.
Reflux cooler for cooling particles and extrudate.Temperature (hot) particles into the cooling chamber, suction fan will indoor air out of the surrounding air from the bottom of the fresh into the cooling chamber, promote grain cooling effect.When the particle accumulation and access to the high limit yuan sensor, pneumatic discharge valve will be action to discharge the product immediately.Countercurrent air heat exchange to ensure high cooling efficiency.
