The Danteco Bitumen Bag Decanter is also known as a big-bag bitumen melting machine and a bitumen melter. It uses direct-fired flame-tube heating or hot-oil (thermal oil) circulation to transfer heat to the unique Bitumen Bag Decanter. It is a special-purpose iso bitucontainer mainly applied to melt the solid bitumen stored and shipped in 1MT bags (big bags). The liquid bitumen can be used for asphalt plants or asphalt terminals to supply hot bitumen to other clients, produce asphalt mix, and for other industrial purposes.
The Bitubag Decanter is based on a modular double-skin 20ft Bitumen container fitted with heating pipes and diesel burners. A 1.2 m x 1.2 m removable hatch is built into the tank's roof and can be removed using the provided lifting sling.
(1MT) One-ton bitumen bags are fed through a 1.2 x 1.2-meter removable top hatch. Cutting the bottom of the PP bag with the provided tool will allow the bitumen to slide gently into the tank. By the time the next bag is trimmed, the previous one has dispersed into the tank. A total of 20 one-ton bags can be loaded per charge, matching one shipping container full of bags. Upon completion of the charge, the top hatch is returned to the roof, the roof chimneys are opened, and the burners are started.
The heating system consists of two (2) Max 8TL diesel burners permanently fitted to the heating pipes at one end of the container. Heating can be monitored using a thermometer mounted near the discharge valve. During initial heating, this thermometer can be unscrewed and inserted into a sensor pocket halfway up the tank to guard against overheating of the bitumen; in that case, the burners can be temporarily switched off or alternated between left and right. Instead of moving the thermometer, it is recommended to insert a second thermometer into the pocket halfway up and set the burners to a timer to regulate the heat.
Charging the Decanter: Decanter out for 2 hours. The heating cycle will take 8-10 hours, depending on the final temperature and whether the decanter is kept running.
Once the desired temperature has been reached, as evidenced by the thermometer next to the discharge valve, switch off the burners, connect the discharge hose and open the discharge valve. To assist the initial flow, it is recommended to heat the discharge valve with an LPG or diesel torch.
Operational Requirements
Single-phase electric power for the diesel burners and a drum of diesel fuel. Two workers are required to feed the bags in. Lifting the bags is usually done with a forklift with extended forks, a truck-crane arm, or a small mobile crane.
Tips for Safe Operation
1. The removable top hatch has water drainage ducts on both sides; however, during heavy rain, the ducts may be unable to cope with the flow. Cover the hatch with a tarp when needed, and always check for water before filling the tank.
2. To avoid corrosion, place the decanter on concrete blocks, one on each corner, of sufficient height to prevent flooding.
3. Always empty the bitumen hose after discharge to avoid blockage.
