Working Principle & Structure
The JLG-III series uses a combined heat exchange structure. Fuel burns uniformly on a mechanized chain grate, generating high-temperature flue gas that heats fresh air through a heat exchanger to the target temperature. Clean hot air is output for drying equipment, while flue gas is dedusted through a gravity settling chamber before low-temperature emission.

Component |
Function Description |
|
|
Fuel spreads evenly on the chain grate for complete combustion and high thermal efficiency |
|
|
Automatically feeds fuel into the furnace, reducing manual labor and maintaining continuous combustion |
|
|
Automatically removes combustion residue, keeping the grate clean and preventing slag buildup |
|
|
High-temp flue gas indirectly heats fresh air, outputting clean hot air free of pollutants |
|
|
Dust settles naturally by gravity with no moving parts, low resistance, long service life and minimal maintenance |
|
|
Connects to dryer air inlet, distributing hot air evenly into the drying section for stable temperature |
|
|
Automatically adjusts fuel supply to precisely control outlet temperature, preventing material overheating |
Key Features & Advantages
|
Key Feature |
English |
|
|
Supports 7 fuel types — choose based on local resources and prices, avoiding dependency on a single energy source. |
|
|
600,000 to 9,600,000 kcal/h across 10 models — covers small farms to large processing plants without custom orders. |
|
|
Outlet temperature reaches 700°C, rapidly raising drying temperature to shorten drying time and increase capacity. |
|
|
Exhaust temperature of only 110–125°C indicates high fuel utilization rate and low operating costs. |
|
|
Mechanized chain grate with auto feeding and slag removal eliminates 24-hour manual attendance, significantly reducing labor costs. |
|
|
No moving parts, low resistance, service life over 10 years, minimal maintenance — no frequent filter replacement needed. |
|
|
Grain processing plants can use rice husk waste as fuel directly, reducing fuel cost per ton by over 30%. |
