Introduction:
Sawdust dryer is widely used in straw briquetting fuel, charcoal machinery, sawdust pellet fuel, sawdust briquetting, agricultural and animal husbandry engineering and other industries. Such as corn straw drying, soybean straw drying, cotton straw drying, wheat straw drying, sorghum stalk drying, sawdust drying, particle drying, sawdust drying, ginkgo leaf drying, mulberry leaf drying and other agricultural cellulose materials drying.
Sawdust dryer uses screw conveyor to continuously add wet sawdust with powder particles into drying and drying pipe. In the transportation and dispersion of high-speed hot air flow, the moisture in wet materials is evaporated to obtain powder or granular dry products. This machine is mainly composed of air heater, feeder, air drying pipe, cyclone separator, fan, etc.
Working principle:
Sawdust dryer: including heating furnace, feed inlet, rotating drum, filter drum, material conveying pipe, cooling drum and discharge port. The rotating drum is located on the driving roller, which is driven by the motor and deceleration drive to rotate at a low speed. There is a feed inlet between the heating furnace and the rotary drum, and there are stir frying blades in the rotary drum. A baffle plate is set at the connection between the rotating drum and the filter cylinder, and the baffle plate is opened on the baffle There is a small hole, one end of the filter cylinder is connected with the rotating cylinder, the other end is connected with the material conveying pipe, the filter cylinder is provided with a stop block, the bottom of the filter cylinder is provided with a slag discharge hole, one end of the cooling cylinder is connected with the material conveying pipe through a blower, and the other end is connected with the material outlet.
Since the sawdust dryer (dryer) adopts 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 moisture can evaporate quickly. The blocking block can block the impurities in the sawdust and ensure the quality of the sawdust entering the material conveying pipe. The sawdust enters the sawdust dryer, and the material boils and fluidizes in the cylinder through the joint action of the spray pipe and the rotary cylinder, and the hot air fully contacts with the material to complete the drying. The utility model has the advantages of simple structure, convenient use and the like.
Advantage:
1. Due to the high dispersion of materials in the air flow, the whole surface of particles is the effective area of drying.
2. Short drying time
3. The air dryer has the advantages of simple structure, small floor area and easy construction and maintenance.
4. Large capacity and high thermal efficiency. When the unconjugated water is dried, the thermal efficiency can reach 60%.

The internal combustion multifunctional is the most ideal drying equipment in the market. It can dry up to 85% of all kinds of powder and dregs, such as feed, fish meal, soybean dregs, sawdust, wood powder, beer grains, alcohol grains, fruit dregs, drug dregs, pond slag, starch residue, etc. The drying volume is large and the efficiency is high. The dried materials are clean and keep the original ones. After cooling, they can be packed and stored.
