The DZG Vacuum Ribbon Dryer (also known as horizontal ribbon blender dryer) is an advanced vacuum drying system that combines high-efficiency drying, crushing and powder mixing in one fully enclosed unit. As an innovative industrial dryer, this vacuum ribbon dryer delivers 3-5 times higher drying efficiency compared to conventional double cone rotary vacuum dryers of similar specifications.
The DZG Vacuum Ribbon Dryer is mainly used for powder drying in the pharmaceutical,chemical,pesticide, food and other industries.
The DZG vacuum ribbon dryer (also called horizontal ribbon dryer) features a heated conical vessel with jacket for hot water, thermal oil or low-pressure steam circulation, maintaining constant wall temperature.
This industrial dryer's operation includes:
(1) A variable-speed motor drives the single spiral ribbon agitator (15-30 rpm) through gear reducer
(2) Material moves upward along the cone wall then falls back by gravity, creating continuous 3D mixing
(3) Efficient heat transfer occurs through:
Jacket conduction (primary)
Ribbon surface contact (secondary)
Under vacuum (-0.08~-0.095MPa), moisture evaporates at low temperature and is removed by:
Water vapor condensation
Optional solvent recovery system
Advantages of PLG Continuous Disc Dryer
1. The working process of DZG series vacuum ribbon dryer is intermittent batch operation.
Wet materials are loaded into the silo and heated through both the cylinder jacket and hollow ribbon screw, providing 140% heating surface coverage for uniform drying. The cone-shaped drying mixer is available in various working volumes to achieve optimal results. Featuring an upper-drive structure, this dryer combines high-efficiency drying and mixing capabilities with easy maintenance access due to its spacious design.
2. Smooth operation and protect crystal shape:
The DZG vacuum ribbon dryer (also known as conical screw dryer in industrial applications) achieves gentle and efficient drying without auxiliary tools. Its unique conical screw design provides complete material movement through lifting, shearing and dispersing actions, while avoiding unnecessary compression or friction between particles and equipment. This friction-free operation is the key reason why the DZG dryer can perfectly maintain material crystal structure integrity throughout the drying and mixing process.
3. The top drive eliminates the possibility of contamination of the product caused by the shaft seal:
Using top drive, relative to bottom drive, this device can avoid the following disadvantages:
The stirring paddle must be disassembled with special equipment for cleaning and maintenance
The shaft seal of the stirring paddle adopts a mechanical seal.
4. Low cost of operating energy consumption and high mixing efficiency:
The DZG vacuum ribbon dryer (industrially referred to as conical screw dryer) features a unique motor-driven design where the rotating screw efficiently lifts materials without requiring additional discharge energy. This dryer employs a conical ribbon mixing system that revolves around the central axis of the conical chamber, ensuring thorough agitation of all materials. The screw gradually elevates materials from the bottom to the top of the vessel, allowing them to naturally cascade down in a continuous cycle. This innovative mixing mechanism guarantees homogeneous blending, prevents material agglomeration during drying, and significantly enhances both mixing and drying efficiency. Additionally, the DZG vacuum ribbon dryer offers broad processing capacity and demonstrates remarkably low energy consumption per unit mass, making it an energy-efficient solution for industrial drying applications.
5. Simple operation and convenient maintenance:
DZG series vacuum ribbon dryer has a simple and effective structure, which is easy for the operator to understand, and the simple button control makes the operation process very simple. Some maintenance work can be completed smoothly and quickly even without professionals. The manhole can be easily adjusted and maintained with the moving screw without complicated disassembly.
