Aluminum UBC can paint stripping machine
Continuous carbonization pyrolysis technology is an efficient and environmentally friendly treatment method, which is widely used in the depainting and recycling of materials such as aluminum beverage cans (UBC). This technology not only improves the recycling rate of aluminum but also reduces production costs, becoming an important solution in the field of aluminum can recycling.

This technology heats the material in an oxygen-deficient or low-oxygen environment to cause the organic coating on the surface to decompose and fall off. The whole process can be divided into the following key stages:
Drying and preheating stage: In this stage, the material is preliminarily treated at a temperature range of room temperature to 130°C, aiming to evaporate the internal moisture and prepare for the subsequent pyrolysis process.
Volatile analysis stage: When the temperature rises to between 130°C and 450°C, the organic matter gradually decomposes under the action of heat and releases volatile gases. This stage is an important link in removing the coating.
Carbonization stage: When the temperature exceeds 450°C, the coating on the surface of the material begins to completely decompose and fall off, leaving clean aluminum, and laying the foundation for subsequent recycling.
Continuous carbonization and pyrolysis equipment usually consists of the following key components:
Segmented heating furnace: The equipment adopts multi-stage independently controlled heating technology to ensure the optimal processing temperature at different stages, thereby improving the overall processing effect.
Continuous conveying system: Through devices such as screw conveyors, the material keeps moving continuously throughout the entire processing process, which significantly improves production efficiency.
Oil and gas separation system: The oil and gas mixture produced during the pyrolysis process is treated by a separator to ensure the purity of bio-oil and pyrolysis gas for subsequent use.
Biochar cooling system: The separated biochar is treated by a circulating water cooling system to ensure safe storage and subsequent use.
Equipment using continuous carbonization and pyrolysis technology has many advantages:
Efficient processing: The continuous design enables the equipment to process a large amount of material, significantly improve production efficiency, and meet large-scale recycling needs.
Environmental protection and energy saving: The pyrolysis and carbonization process effectively reduces the emission of harmful substances, while being able to recover pyrolysis gas and bio-oil, enhancing resource utilization.
Quality control: The segmented heating technology ensures precise temperature control at each stage, thereby ensuring the processing effect and the quality of the final product. Conclusion
Continuous carbonization cracking technology has shown broad application prospects in the aluminum can recycling industry. This efficient and environmentally friendly treatment method can effectively improve the recycling rate of aluminum materials, reduce production costs, and is environmentally friendly.
