Bark dryer

Product introduction

product description
Bark dryer Scope: for straw briquetting fuel, charcoal machinery, wood pellet fuel, sawdust briquetting, agriculture and animal husbandry engineering and other industries. Such as corn stalks drying, drying of soybean stalks, drying of cotton straw, drying of wheat straw, drying of sorghum stalks, drying of wood chips, drying of wood shavings, drying of sawdust, drying of ginkgo leaves, drying of mulberry leaves and other agricultural fibers Category material drying.
Bark dryer Overview: bark dryer refers to the crushed powdery granules wet bark, the use of a screw conveyor to join the drying tube. In the transport and dispersion of the high-speed hot gas stream, the moisture in the wet material is evaporated to obtain a powder or granulated product. Mainly by the air heater, feeder, air drying tube, cyclone separator, fan and other components.

working principle
The working principle of bark dryer
Bark drying machine: including the heating furnace, the inlet, the rotating cylinder, the filter tube, the material conveying pipe, the cooling cylinder and the discharge mouth, the rotating cylinder is on the active roller, the active roller is driven by the motor and the deceleration drive. The rotating cylinder is provided with a feeding port between the heating furnace and the rotating cylinder. The rotating cylinder is provided with a frying blade, and a baffle is arranged at the connecting position of the rotating cylinder and the filter cylinder, and a hole is arranged on the baffle plate, And the other end is connected with the material conveying pipe. The filter barrel is provided with a blocking plate. The cooling cylinder is connected with the material conveying pipe through a blower and the other end is connected with the discharge port.
Since the bark dryer (dryer) adopts the above structure, the bark can be sufficiently dried in the rotating cylinder, and the bark is fully dispersed again before entering the material conveying pipe, so that the water evaporates quickly, The impurities in the skin block to ensure the quality of the bark into the material delivery pipe. Bark into the bark dryer by the injection tube and rotary cylinder together, the material boiling in the tube fluid, hot air and material full touch, complete the dry. The utility model of cellulose material drying equipment has the advantages of simple structure, easy to use, etc., by the majority of customers welcome.
Performance characteristics
Bark dryer features
1, The drying strength is large, because the material is highly dispersed in the air flow, the total surface area of the particles is extremely dry effective area.
2, Dry time is short, dry moisture control.
3, The new sawdust dryer structure is simple, small footprint, easy to build and repair.
4, Handling capacity, high thermal efficiency. When dry non-binding water, the thermal efficiency of up to 60%.
