50% energy-saved hot air flow type sawdust dryer

Drying is important before briquetting process. To get the superior quality of biomass briquettes with high density, it is necessary to control the moisture of material at 8-12% exactly. The selection of drying plant models depends on the original moisture content of raw materials.

(1)Hot airflow type dryer

Wood dryer is suitable for drying materials like sawdust, rice hull, milling wheat straw, corn stalks and so on. The moisture of wet materials is at 20-30%. The wood dryer is equipped one fuel boiler, inlet, steel pipe, exhaust blower (fan), cyclone. Wet materials are input into the hopper. The fuel boiler generates hot air which mixes with wet materials and then is sucked into the pipes by the exhaust blower (fan) quickly. And then hot air is flowing and going though the curving pipes and buffer (drying chamber) of dryer, thus wet materials is finished to dry, and the dried materials are expelled out by the exhaust blower (fan). This wood dryer reduces the moisture to 8-12% with the advantages of lower cost consumption and high efficiency.

Model	Capacity (kg/h)	Power	Package size (m)	Consumption of Wood Waste (kg/h)	Weigh (kg)
QHJ-4	300-400	4kw	1.5X1.22X0.98+2.3x1.4x1.5	10-15	1500
QHJ-6	400-500	5.5kw	1.45x1.2x1.0+2.5x1.9x1.5	25-30	1800
QHJ-8	600-700	11kw	2.4x0.8x1.5+2.7 x2.1 x1.9	35-40	3000

(2)Rotary drum dryer

The rotary dryer is your best choice for high capacity applications involving high moisture, friable, free-flowing commodity products and by-products. shows the features of perfect drying effect, easy-operation, Rotary Dryer is special designed to dry the Wood material which combines the function of drying and cooling, so it can save 30-50% energy.
Rotary type dryer shows the features of perfect drying effect, easy operation, high efficiency and easy control of drying. It takes advantage of the stability of roller and homogeneity of air.
suitable for drying materials of moisture 30-60% It has the larger capacity , can meet the high capacity needs.
