Second hand hot air tray dryer

Introduction to hot air disc dryer

1. Efficient Drying Technology: The hot air disc dryer is an efficient drying system that utilizes hot air to rapidly remove moisture from various materials, including powders, granules, and agglomerates.
2. Disc Configuration for Uniform Drying: The dryer features a disc-shaped design where the material is spread out on multiple rotating discs. This configuration allows for uniform drying as the material is continuously exposed to the hot air stream.
3. High Heat Transfer Rates: The design of the hot air disc dryer promotes high heat transfer rates between the material and the hot air, ensuring quick and effective moisture evaporation.
4. Adjustable Parameters for Control: Advanced models often come equipped with adjustable parameters such as disc speed, air temperature, and airflow, providing precise control over the drying process to meet specific material requirements.
5. Versatility in Material Handling: The hot air disc dryer is versatile and suitable for a wide range of materials, making it applicable in industries such as chemicals, pharmaceuticals, and food processing.

Working principle of hot air disc dryer

1. Material Loading: The material to be dried is loaded onto the rotating discs of the second-hand hot air disc dryer. The discs are typically arranged in a circular fashion.
2. Rotation of Discs: The discs rotate, causing the material to spread out evenly across their surfaces. This rotation exposes the material to the hot air stream from the dryer.
3. Hot Air Introduction: A stream of hot air is introduced into the drying chamber. The hot air is heated using a heating source such as electric heaters, gas burners, or steam coils.
4. Contact between Hot Air and Material: The hot air comes into direct contact with the material on the rotating discs. This contact initiates the heat transfer process, leading to the evaporation of moisture from the material.
5. Continuous Drying: As the material progresses along the rotating discs, it undergoes continuous drying. The combination of heat transfer and mechanical agitation facilitates efficient moisture removal.
6. Moisture Evacuation: The moisture evaporated from the material is carried away by the hot air stream. The design of the dryer often includes mechanisms for collecting and evacuating the moisture-laden air.

The advantages of hot air disc dryer are as follows

1. Uniform Drying: The hot air disc dryer is characterized by its ability to achieve uniform drying across the material due to the rotating disc configuration. This ensures consistent moisture removal from the entire product surface.
2. High Heat Transfer Efficiency: The design of the rotating discs allows for excellent heat transfer between the hot air stream and the material. This high heat transfer efficiency contributes to the rapid evaporation of moisture.
3. Precise Temperature Control: Advanced hot air disc dryers often feature precise temperature control systems, allowing operators to adjust and maintain optimal drying temperatures for different materials.
4. Continuous Operation: The continuous rotation of the discs facilitates a continuous drying process, making it suitable for large-scale industrial applications where a consistent flow of dried material is required.
5. Versatility in Material Handling: Hot air disc dryers are versatile and can handle various materials, including powders, granules, and agglomerates. This versatility makes them applicable in diverse industries such as chemicals, pharmaceuticals, and food processing.
