Heat Transfer Area 29M2 Textile Sludge Hollow Paddle Dryer
Paddle dryer is a kind of low-speed agitated dryer with agitated pulp inside the equipment to make the wet materials fully contact with heat carrier and hot surface under the stirring of paddles, so as to achieve the purpose of drying. The structure is generally horizontal, double axis or four axis. The paddle dryer is divided into hot air type and conduction type. The hot air type is through the heat carrier (such as hot air) and the material to be dried contact and drying.
Product Working Principle
Wedge shaped hollow blades are densely arranged on the hollow shaft, and the hot medium flows through the hollow shaft. The heat transfer area per unit effective volume is very large. The temperature of hot medium ranges from - 40 ℃ to 320 ℃, which can be steam or liquid type, such as hot water, heat transfer oil, etc. Indirect conduction heating, without carrying air to take away heat, heat is used to heat materials. The heat loss is only the heat dissipation to the environment through the insulation layer. The heat transfer surface of wedge blade has self-cleaning function. The relative movement of material particles and the wedge-shaped surface produces a washing effect, which can wash off the attached materials on the wedge-shaped surface, and keep a clean heat-transfer surface during operation. The shell of the pulp dryer is Ω type, and two to four hollow mixing shafts are arranged in the shell. The shell has a sealed end cover and an upper cover to prevent the leakage of material dust.
The heat transfer medium flows through the shell jacket and the hollow mixing shaft through the rotary joint. The hollow mixing shaft has different internal structure according to the type of hot medium, so as to ensure better heat transfer effect.
Product Feature
Technical Advantage
1) High thermal efficiency which can reach 95%
2) Heat transfer medium does not contact the product.
3) Gas is not used to convey the product. Off-gas flow is minimal.
4) Precise control of temperature
5) Uniform product quality, through mixing and movement of the product
6) Continuous process on a once-through basis
7) High heat transfer area to process volume ratio - reduced floor space
8) Easy to operate, requires minimal attention
9) Safer than direct drying when processing combustible material
10) Simple durable design for easy and low maintenance
11) Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing, uniform heat transfer, a high heat transfer rate, and a self-cleaning effect.A large heat transfer area to volume ratio is achieved by the use of hollow discs and a jacketed vessel, through which the heating medium flows. The result is a compact machine with less space requirements and lower installation cost.
Product Application
• The materials from such as the medicine t food , chemical industry, etc. can be dried.
• Suitable for pulpiness, paste-like mixture or power raw material.
• Temperature sensing material requiring the low temperature to be dried.
• Raw materials that are easy to oxidize or explode and have strong irritative or toxic.
• Demand to retrieve of the organic solvent.
