Dryers

Dryers

Drying is a thermal process used to remove moisture or solvents from solid or semi-solid materials, reducing their content to a controlled level for the next stage of production. In high-precision industries such as lithium-ion battery material production, pharmaceuticals, and fine chemicals, where consistency and reliability are critical, effective drying directly impacts product quality, handling efficiency, and process stability.

Our drying systems are also widely used in broader sectors including food ingredients, environmental treatment, and other advanced industrial applications. Each dryer is selected and configured based on material form, thermal characteristics, and specific customer requirements, ensuring reliable performance and process alignment.

Customized Drying Equipment

We design and manufacture tailored drying systems for lithium battery materials, pharmaceuticals, chemicals, and food processing industries, supporting complete turnkey solutions from concept to installation.
    1. Rotary Tray Dryer
    2. Rotary Tray Dryer
      Drying area 3.3-168m²
      Power 1.1-18.5kW
      The rotary tray dryer is a highly efficient continuous conductive dryer utilizing an indirect heating system, designed for uniform moisture removal from powders and granules. We offer this industrial drying equipment in various configurations, including atmospheric, sealed, vacuum, and positive pressure types, to suit a wide range of drying requirements. View Details
    1. Paddle Dryer
    2. Paddle Dryer
      Heat transfer area 1-300m²
      Motor power 1.5-220kW
      The paddle dryer is a horizontal, indirect heating dryer with integrated agitation, designed for drying, heating, cooling, crystallization, and thermal reactions of pastes, sludges, powders, and granules. It operates on the principle of heat conduction and is engineered for efficient thermal processing of materials with varying consistency. The core structure features a W-shaped shell with jacket housing one or more pairs of hollow, low-speed rotating shafts with welded paddle blades. View Details
    1. Spin Flash Dryer
    2. Spin Flash Dryer
      Dimensions 6500×4200×7530mm
      Power 1.1-55kW
      The spin flash dryer is a vertical drying system equipped with a built-in rotating disperser, combining the functions of fluidized bed drying and airflow drying in a single unit. It is designed for the continuous drying of filter cakes, pastes, and slurry-like materials. This drying equipment not only dries but also pulverizes and classifies materials during the drying process, making it ideal for materials with high moisture content and poor flowability.

    1. Fluid Bed Dryer
    2. Fluid Bed Dryer
      Fluid bed size (L×W) 8000×1500mm
      Vibration motor power 5.5×2kW
      The fluid bed dryer applies mechanical vibration to a conventional fluidized bed system, improving material movement and heat exchange efficiency. Under the combined action of vibration and airflow, the material enters a fluidized state and moves continuously along the bed. As hot air passes through a perforated distribution plate, it makes direct contact with the material, facilitating effective heat and mass transfer. View Details
    1. Vertical Ribbon Vacuum Dryer
    2. Vertical Ribbon Vacuum Dryer
      Inner diameter 500-2300mm
      Power 1.5-22kW
      The vertical ribbon vacuum dryer is a conductive vacuum drying system designed for efficient, low-temperature drying of moisture-sensitive materials. It operates in batch mode with a jacketed vessel, allowing for precise thermal control. Material is fed from the top of the dryer and continuously agitated by a helical ribbon stirrer, ensuring uniform mixing and direct contact with the heated surfaces. Heat transfer media such as steam, hot water, thermal oil, or molten salt can circulate through the jacket, main shaft, and ribbon blades, maximizing heat distribution throughout the product.

Based on operating experience, the full drying cycle, starting from material feeding to the discharge of dried products, takes 30 to 40 minutes. The exact time depends on the dryer model and rotation speed of the main shaft.

Drying efficiency is influenced by several factors, including:

  • Material properties (e.g., initial moisture content, particle size)
  • Target final moisture level
  • Operating conditions (e.g., temperature, steam pressure, shaft speed)
  • Design parameters (e.g., number of trays, heat transfer surface area)

To maintain optimal moisture levels, consider the following:

  • Adjust temperature and rotation speed appropriately
  • Control the feeding rate and main shaft speed
  • Monitor and fine-tune the operation regularly
  • Account for the specific properties of the material being dried
  • Perform routine inspection and maintenance

The paddle dryer is suitable for processing various materials such as pharmaceuticals, food ingredients, and chemicals. Depending on the application, the heating temperature can reach up to 400°C (750°F).

Fuel options vary by system configuration and may include natural gas, light or heavy fuel oil, coal, petroleum coke, and even hydrogen, depending on the heat source design.

Typical inlet air temperatures range from 300°F to 1500°F (150°C to 815°C), while exhaust air temperatures usually fall between 170°F and 250°F (77°C to 120°C), depending on the material and drying requirements.
