History of woodchip dryer
Wood chaff is the wood small particles and powder produced when people saw the wood, the general wood processing plant has one to a dozen tons of wood chaff produced every day, usually are piled up like a mountain, placed to weathering and moldy, wasting resources, causing pollution and damage to the environment. In recent years, some people research and develop the utilization of wood bran, used to replace the original coal and oil fuel of the boiler, that is, wood bran sprayed to the combustion chamber of the boiler, the heat produced is comparable with the boiler of burning general coal, and the cost is only 1/2 of burning coal, the smoke and dust discharged is greatly reduced than that of burning coal, the economic effect is remarkable, which is beneficial to the protection of the environment, energy saving and the production of the enterprise. Therefore, wood drying kiln is popularly used in small and medium-sized enterprises.
As the wood is sawed when the contact surface between the saw and the wood is put water for cooling, so the sawed-out wood bran are wet and contain great water content. The wood bran of the existing kiln dryer has to be dried before it is sprayed into the boiler combustion chamber for combustion. The wet wood bran drying needs the larger site and the more time, in the wood bran drying and the process of collecting after drying is very time consuming and laborious, if the wind will blow away many wood’s saw dust, like the sandstorm all over the sky, to the environment pollution and the economic loss; Especially in the rainy day, the drying wood bran becomes a great problem. At this time, kiln dryer machine's fuel is waiting for the rice under the pot or no rice under the pot, wood bran boiler's fuel can't be guaranteed.
At present, the wood chip dryer is transformed to simplify the work flow in the production process which is prone to problems, so that workers can save more time and effort. The self-developed dryer not only has the advantage of technology, but also follows the principle of drying wood bran to optimize the dryer equipment. Make the dryer more specialized and humanized. Not only the output is high, the drying degree is stable (initial moisture 40%, final moisture 15%, the output can reach more than 2 tons per hour) and the structure is simple, the cost is low.
Working principle of woodchip dryer
Wood chips and sawdust materials are conveyed by belt conveyor to the closed air feeder into the hot air furnace for combustion, and the resulting high temperature gas enters the dryer through the fire separator. The raw materials enter the drum dryer through the screw feeder, and the high temperature airflow passes through the materials through low-speed rotation and bending plate to disperse the materials, and then the suction of the fan pushes the materials forward, and the materials are discharged from the closed fan through the shake-long at the other end.
Structure of woodchip dryer
Wood chip dryer machine is mainly configured by hot air furnace, closed air feeder, belt conveyor (can be equipped by itself), screw feeder, drum airflow dryer, fan, shake-long, closed fan and so on. This sawdust dryer machine combines the advantages of airflow and drum dryer, with high efficiency and good effect, low investment cost and small footprint.
Type of woodchip dryer
Air-flow wood chip dryer
Air-flow wood chip drying equipment is a machine that continuously adds the wet sawdust in the form of powder and granule into the drying tube by using screw conveyor, and evaporates the moisture in the wet material in the conveying and dispersing of high-speed hot airflow, so as to get the powder or granule dried products. Woodchip dryer is mainly composed of air heater, airflow drying tube, cyclone separator, feeder, fan, and so on. This kind of wood chip dryer has the smallest output and is generally used with other equipment, which is one of the charcoal machine series products.
Drum wood chip dryer
Drum type wood chip dryer is a kind of dryer that handles a large amount of materials. It is widely used in metallurgy, building materials, foodstuff, light industry, chemical industry, coal, medicine and mining industry because of reliable operation, large flexibility of operation, strong adaptability and large processing capacity. Rotary drum dryer is generally adapted to granular materials, and it can also be used to dry viscous paste materials or materials with high water content by partially mixing into the materials.
Drum drying wood chip equipment is highly adaptable, occupies a small area, has a large processing capacity and mature technology, and is used for drying and granulating wood chips to process biomass pellet fuel, which can reduce the production cost to a greater extent and improve the molding rate and quality.
Heat-conducting tube type wood chip dryer
Sawdust dryer adopts heat-conducting tube to heat the material indirectly, so that the material and the heat source can be fully contacted and the water steam can be discharged from the top of the equipment in real time, and the heat source is heated by hot air furnace without consuming steam, which has the advantages of good drying effect, reasonable structure, large output, low energy consumption, convenient installation, simple operation and wide adaptation range, etc. It is the ideal special equipment for sawdust, wood chips and other powder materials.
