Sawdust Dryer
Product Description
Working Purpose of Sawdust Dryer
Sawdust Dryer refers to taking wet sawdust in powdery and granular form and using a screw conveyor to continuously add and dry it
inside the tube. In the transportation and dispersion of high-speed hot air flow, the water in the wet material is evaporated to obtain a powdery or granular dry product. It is mainly composed of air heater, feeder, air drying tube, cyclone separator, fan, etc.
Features of sawdust dryer
High drying intensity. Since the material is highly dispersed in the air flow, the entire surface area of the particles
Extremely dry effective area
Short drying time
. The air flow dryer has a simple structure, small footprint, easy construction and maintenance
, large processing capacity and high thermal efficiency. Thermal efficiency is achieved when drying unbound water.
Working principle of sawdust dryer
Sawdust dryer includes heating furnace, feed port, rotating cylinder, filter cylinder, material conveying pipe, cooling cylinder and discharge port, rotating The drum is located on the active roller. The active roller drives the rotating drum to rotate at low speed by motor and reduction transmission. There is a feed port between the heating furnace and the rotating drum. There is a stir-frying blade in the rotating drum. There is a baffle at the connection between the rotating drum and the filter drum. There is a small hole
on the baffle. One end of the filter drum is connected to the rotating drum and the other end is connected to the material conveying pipe. There is a
inside the filter drum. There is a stopper and a slag discharge hole at the bottom of the filter cylinder. One end of the cooling cylinder is connected to the material conveying pipe through a blower, and the other end is connected to the discharge port.
Due to the above structure, the sawdust can be fully dried in the rotating drum, and the sawdust is fully dispersed again before entering the material conveying pipe, so that the water evaporates quickly, and the block can remove impurities in the sawdust
br/>Block to ensure the quality of sawdust entering the material conveying pipe. When the wood chips enter the sawdust dryer, the blow pipe and the rotating cylinder work together. The material boils and fluidizes in the cylinder, and the hot air fully contacts the material to complete the drying. The utility model has the advantages of simple structure and convenient use.
There is a big difference between sawdust drying and finished product drying. Since the sawdust is loose, the distance of water movement
is short. When drying wet sawdust, when the moisture contained in the sawdust exceeds its equilibrium moisture and is interspersed with the drying process,
When in contact with the sawdust, the dryer transfers heat to the surface of the sawdust, and then the heat is conducted from the surface to the interior.
Scope of application of sawdust dryer
Air flow sawdust dryer is widely used in straw briquetting fuel, charcoal machinery, wood pellet fuel
sawdust briquetting, agricultural and animal husbandry engineering and other industries . Such as corn straw drying, soybean straw drying
, cotton straw drying, rice drying machine, etc.
