The Danteco Bitumen Bag Decanter Thermal-Oil Type, also named big bag bitumen melting machine and bitumen melter. Via a thermal oil (hot oil) circulating and transferring 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 other industrial purposes.

The Bitubag Decanter is based on a modular double-skin 20ft Bitumen container fitted with an internal heating pipe system for thermal-oil (hot-oil heating. A 1.2 m x 1.2 m removable hatch is built into the tank's roof, which is removable using the lifting sling provided.

(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 tool provided will see the bitumen gently slide 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. On completion of the charge, the top hatch is placed back onto the roof, the roof chimneys are opened, and the burners are started.

The heating system consists of a bed of 2" heating pipes permanently fitted on the bottom of the container. Heating can be monitored with the help of a thermometer mounted near the discharge valve. 

Charging the Decanter takes about 2 hours. The heating cycle will take 8-10 hours, depending on the end temperature and whether or not the decanter is permanently kept in operation.

Once the decided temperature has been reached, as evidenced by the thermometer next to the discharge valve, switch off the heating, 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

Thermal-Oil Installation to provide hot oil to be pumped via oil-in and oil-out DN200 connection on the decanter tank. Two workers are required to feed in the bags. Lifting the bags is usually done via a forklift with extended forks, 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; always check for water before filling the tank.
2. To avoid corrosion, place the decanter on four concrete blocks, one on each corner of sufficient height to prevent flooding.
3. Always empty the bitumen hose after discharge to avoid blockage.
