Use dryer to save the cost of charcoal production machine

Hot air flow pulse dryer is also called pipe dryer. It is an important equipment of charcoal production mechanism and an important link in the process of charcoal making machine. Its work is characterized by feeding granular wet materials into the hot gas stream, which flows together with it, thus producing granular dry products. A new efficient and energy-saving dryer, which is connected by double cylinder and double layer pipe, is used to dry sawdust, rice husk, peanut shell and straw at one time.

The drying machine adopts self-made gas as heating source and drying as two parts: roller part and serpentine pipe part. Drum part: inner drum, external insulation two layers. The inner drum is equipped with three inner screw sheets, which can make the drying materials walk evenly, known as frying heating. The serpentine tube USES the heat source for the second time, and USES the suction fan to pump the drying materials into the screw for separation to achieve the drying effect. The existing wood chip dryer generally USES coal and wood as heat source. High labor intensity, high cost, high loss of thermal efficiency, less than 30% thermal utilization, the original half bucket with 35% water content in general should be dried 3-4 times, and the gas rotary dryer can make the raw material with 35% water content dry successfully in one time, and electricity saving 75% can greatly reduce the drying cost. The gas source of the dryer is the methane gas produced by the carbonization of the carbonization furnace. Comprehensive budget estimate: it can save drying cost nearly ten thousand yuan per year.

The advantage of this dryer is direct heating, fast drying, can be folded installation, space savings. The principle is to let the wet raw material walk in the pipeline with the high temperature air flow, through the separator to get water content meet the requirements of raw materials.
