The double drum drum scraper dryer is an internally heated conductive rotary continuous drying equipment. The rotating drum is adhered to a thick film through its lower chute, and heat is transported to the inner wall of the drum through pipes, conducted to the outer wall of the drum, and then transmitted to the film, causing the humidity in the film to evaporate, dehumidify, and dry the material containing moisture. The dried material is removed from the drum by a scraper installed on the surface of the drum and transported to a screw conveyor placed below the scraper. The dry material is then collected and packaged by the screw conveyor. This machine is widely used in industries such as food, chemical, and pharmaceutical for the production and drying of viscous and paste like materials.
The double drum drum scraper dryer is a commonly used drying equipment, and the following points should be noted when using it:
• Pre treatment: Ensure that the material has been pre treated before entering the double drum scraper dryer, such as cleaning large debris and excessive moisture, to avoid equipment blockage and excessive wear.
• Startup sequence: When starting the device, the correct sequence should be followed. First, start the drum, then start the scraper and heating system.
Temperature control: During use, it is necessary to strictly control the temperature of the dryer to ensure that it does not exceed the bearing range of the materials and equipment, and to avoid material adhesion and equipment damage.
Uniform distribution of materials: Ensure that materials are evenly distributed inside the dryer to avoid local accumulation, which may affect the drying effect and equipment operation.
• Cleaning and maintenance: Regularly clean the residual materials inside the equipment and perform necessary maintenance to extend the service life of the equipment.
• Operating environment: Keep the operating environment clean and ventilated to avoid the impact of dust and moisture on the equipment.
• Safety precautions: Operators should wear appropriate protective equipment and strictly follow safety operating procedures to prevent accidents.
• Monitoring and recording: Real time monitoring of equipment operation status and drying process, and detailed recording for analysis and optimization of operating parameters.
