Complete Process of Charcoal Briquette Extrusion.
New starters in barbecue charcoal and machine-made charcoal processing often ask how ordinary charcoal raw materials and wood scraps are processed into dense, firm and long-burning solid charcoal sticks.
This article explains the working principle and full production procedure of charcoal briquette machine based on practical operation experience. The content is easy to understand and suitable for factory operation, equipment sales and customer training.
1. Brief Introduction to Charcoal Briquette Machine
Also known as charcoal making machine, it is the core forming equipment on the machine-made charcoal production line. All charcoal sticks are shaped by high temperature and high pressure extrusion.
Main components: power distribution cabinet, main drive motor, heating coil, forming barrel and screw propeller.
It features simple structure, low failure rate and easy operation, widely used in charcoal processing industry.
2. Standard Operating Procedures
Improper wiring, preheating and operation sequence usually lead to operational faults. Please follow the standard steps below.
2.1 Wiring and Power Check
This high-power industrial forming equipment requires three-phase power supply. Single-phase household power cannot support normal operation.
Complete wiring in standard specifications. Check circuit firmness and insulation to avoid electric leakage, tripping and motor failure.
2.2 Start Preheating and Adjust Forming Temperature
Do not feed materials immediately after wiring. Set the temperature controller on the power cabinet to around 300°C.
This is the standard temperature. Fine adjustment is allowed according to material type, moisture content and texture.
Preheating warms up the forming barrel and machine head. It softens raw materials quickly, so as to produce compact charcoal sticks without cracks or looseness.
2.3 Test Operation and Verify Rotation Direction
Test the machine during preheating. Press the forward rotation button and check the indicator light.
Confirm the screw propeller inside the feeding hopper runs in the correct feeding direction. Reverse rotation will cause material blockage, machine jamming and even damage to propeller and motor. This step is essential.
2.4 Constant-temperature Feeding & High-pressure Extrusion
Start feeding materials slowly and evenly when temperature and operation stay stable. Excessive feeding at one time will cause blockage.
Raw materials are pushed forward by the screw propeller. Under high temperature and high pressure inside the forming barrel, materials are fully compressed and shaped.
Uniform solid charcoal sticks are continuously extruded from the outlet.
3. Product Features & Application
The whole process is reliable and easy to operate. Charcoal sticks made by high temperature and high pressure extrusion have high density, firm texture, long burning time, no smoke and no peculiar smell.
They are ideal for barbecue, domestic heating and industrial fuel. This production method is popular for small businesses and charcoal processing workshops.
