Resolving the bottleneck of solid bitumen decanting in remote highway engineering and multinational road construction contracts.
In large-scale cross-border highway construction, international airport runway developments, and municipal pavement rehabilitation, liquid bitumen logistics often present severe economic and physical barriers. Transporting bulk liquid asphalt over sea freight or across non-connected inland road networks requires high-capital insulated tanker fleets and constant thermal upkeep.
To overcome these challenges, oil refineries globally package heavy bitumen, modified asphalt, and emulsion base stocks in standardized steel drums (typically 200kg to 240kg capacity). However, re-melting this solid or semi-solid bitumen at the construction site demands specialized, thermal-efficient machinery: The Industrial Drum Decanter (Bitumen Drum Melting Unit).
As a global leader in road construction equipment engineering, HME TOP Machinery Equipment Co., Ltd. (HEM Group) manufactures state-of-the-art continuous drum decanters designed to minimize energy consumption, guarantee zero carbonization of asphalt binder, and maximize barrel recovery speeds across harsh climatic zones.
Traditional open-flame heating methods result in up to 15% thermal fuel loss and up to 3.5% residue remaining in discarded drums. Modern continuous hydraulic drum decanters equipped with waste gas heat exchange coils reduce total operational thermal requirements to less than 18–22 kg of diesel per ton of melted bitumen, yielding full capital payback within 4–6 operational months.
Discover the multi-stage thermodynamics that make our drum decanting units the premier choice for major road construction contractors.
Heavy-duty hydraulic rams elevate and invert steel drums effortlessly into the melting chamber. Integrated roll-in tracks reduce manual labor and safeguard on-site technicians from high-temperature hazard zones.
Exhaust heat from the main burner is diverted into a specialized upper hood preheating zone. High-temperature flue gas soft-heats drum shells to release solid bitumen blocks rapidly without chemical breakdown.
The lower melting reservoir is lined with high-density seamless thermal oil pipe coils. Maintaining a stable heat distribution (160°C to 180°C), preventing asphalt charring while maintaining high flow rates.
Integrated multi-layer stainless mesh screens continuously strain solid debris, rust scale, and packaging contaminants from liquid asphalt before pumping it directly into asphalt mixing plants or storage tankers.
Sealed melting chambers coupled with anti-leakage rubber gaskets prevent toxic bitumen smoke, volatile organic compounds (VOCs), and heavy vapors from escaping into the environment, fulfilling ISO 14001 mandates.
Engineered according to standard ISO shipping container dimensions. Units can be deployed, assembled, and operational on remote construction sites within 48 hours of delivery.

Combining university-backed scientific research with global industrial manufacturing excellence.
HEM Group was founded in 1998 by an elite group of professors from Chang'an University—the premier institution for highway engineering in China—alongside veteran road construction experts. Originally registered as Xi'an Hongda Communications Technology Co., Ltd., it stands as one of the earliest high-tech enterprises dedicated to independent R&D of advanced road construction equipment.
Throughout more than two decades of technological iteration, HEM Group has earned numerous invention patents in mechanical dynamics, engine power matching, hydraulic transmission systems, and digital electronic controls. In 2006, the company was officially designated as a "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology.

Anticipating industrial sustainability standards, digital controls, and clean thermal energy integration.
Future decanter iterations incorporate real-time infrared thermal mapping and viscosity sensors within the melting sump. By monitoring the exact fluidity state of bitumen, the burner automatically throttles thermal oil output, eliminating energy waste and preventing micro-structural thermal degradation of polymer-modified bitumen (PMB).
As global carbon regulations intensify, our engineering team is integrating secondary electrostatic precipitators and multi-stage dry scrubber filters into the exhaust flue. This neutralizes odor molecules, sulfur oxides, and particulate emissions before discharge.
For regions with access to clean electric power grids or solar field setups, hybrid decanters utilize electric immersion coils backed up by biodiesel-compatible burners. This hybrid flexibility grants contractors independence from volatile fossil fuel pricing.
To support circular economy goals, modern project sites combine decanters with automatic drum flattening units. Cleaned, emptied steel drums are flattened directly at the discharge point for direct recycling back into steel manufacturing loops.
Expert insights on drum decanter selection, operational thermal economics, maintenance, and international compliance.
Our continuous drum decanters utilize indirect heating via closed thermal oil coils combined with recycled exhaust gas hoods. Unlike crude open-flame heating, the thermal oil temperature is strictly regulated between 160°C and 180°C. This ensures bitumen reaches a pumpable liquid state (110°C–130°C) without local overheating, preserving the original penetration index and ductability of the binder.
Thanks to our dual-heating mechanism—where burner flue gas pre-heats the drums while thermal oil melts the fallen bitumen blocks—fuel consumption is exceptionally low. On average, our units consume between 18 to 22 kg of standard diesel fuel per ton of melted asphalt, depending on ambient environment temperatures and drum starting conditions.
Yes. The hydraulic pusher mechanism generates up to 16-20 MPa of thrust, guided along heavy-duty internal steel rails. Even severely dented or deformed drums slide smoothly into the heating zone without jamming or requiring manual pre-straightening.
Drums pass through a continuous high-temperature dripping gallery. The enclosed heating chamber maintains an ambient heat of over 120°C around the drums, causing liquid asphalt to slice cleanly off inner drum walls. Residual bitumen left in drums is proven to be under 0.5% by weight, compared to 3-5% losses in manual heating methods.
Our decanters can be equipped with Italian Riello or Baltur burner assemblies supporting Light Diesel, Heavy Fuel Oil (HFO), Natural Gas, Liquefied Petroleum Gas (LPG), or Dual-Fuel configurations to match site-specific fuel availability.
All HME TOP drum decanters are built in compliance with ISO 9001 quality management, ISO 14001 environmental safety standards, and European CE certification directives for pressure vessels and thermal oil machinery.
