In the northern winter, asphalt barrels freeze into "ice lumps", which is a common problem for construction companies. Traditional heating methods (such as open flame baking and steam direct blowing) can easily cause barrel deformation and asphalt carbonization, and thawing takes up to 6-8 hours, seriously affecting production progress.
The new generation of Bitumen Melting Machine adopts a three-stage composite thawing technology:
Barrel wall steam pre-melting: The spiral steam pipe wraps around the barrel body 360°, raising the barrel wall temperature to 50℃ within 15 minutes to soften the surface ice layer;
Infrared penetration heating: The carbon fiber infrared tube radiates deep asphalt, penetrates the 5cm frozen layer in 30 seconds, and changes the internal asphalt from solid to viscous flow;
Mechanical vibration ice breaking: The hydraulic vibration hammer strikes the bottom of the barrel at a high frequency to destroy the frozen adhesion layer between the asphalt and the barrel wall, and separates the barrel body from the asphalt.
According to actual measurements, under a -30℃ environment, the thawing time of a single barrel can be shortened to within 45 minutes, and the energy consumption is reduced by 30% compared with the traditional method. After thawing, the fluctuation of the asphalt penetration and elongation index is less than ±3%, meeting the JTG F40-2004 construction standard. The Bitumen Melting Machine is equipped with a low-temperature start-up module, which can be started with one button even in a -40℃ environment, completely solving the problem of asphalt debarreling efficiency in high-altitude and cold areas.
