Polyvinyl alcohol petrochemical hollow paddle dryer

  Project description:
  Polyvinyl alcohol, organic compounds, white flakes, flocculent or powdered solid, tasteless. Polyvinyl alcohol is an important chemical raw material for the manufacture of polyvinyl acetal, gasoline pipe and vinylon synthetic fiber, fabric treatment agent, emulsifier, paper coating, adhesives, glue and so on. Jiangsu Jianda Drying Engineering Co., Ltd.developed polyvinyl alcohol dryer, the majority of users have been well received, your trust is our best development momentum.


  First, the principle of polyvinyl alcohol petrochemical hollow paddle dryer:
  The hollow paddle dryer produced by our company is a kind of low-speed mixing which is used to set the hollow stirring blade inside the equipment and pass the heat carrier in the paddle so that the sludge is in full contact with the hot surface of the paddle dryer.

  There are wedge-shaped hollow paddles in hollow axis,and heat medium is from-40℃ to 320℃, the heat medium is steam or hot air or heat conduction oil and so on.The heat medium (such as steam or thermal oil) will flow into chamber jacket and hollow mixing axis through rotary join. Hollow mixing axis has different inner structures according to different types of heat medium, which will ensure of best heat transfer efficient.


  Second, applications:

  The blade dryer is successfully applied in foodstuff, chemical, petrochemical, dyestuff, and industrial mud etc. The heating transferring, cooling and stirring characters enable it to perform the following unit operation: combustion (low temperature), cooling, drying (recovery of solvent), heating (melting), reacting and sterilizing. The stirring blade is heat transferring surface too, so to increase heat transferring area of unit effective volume is increased, and decrease processing time. The chock shaped heat transferring surface has self-cleaning function. Compressing and swell-stirring functions make the material mixed uniformly. The material performs the movement of "piston flow" along the shaft. The difference of the temperature, humidity and mixing effect are very small in the different axial area. The blade dryer is capable to perform combustion under low temperature if we adopt thermal oil as heating media.


  Third, the characteristics of polyvinyl alcohol petrochemical hollow paddle dryer:
 

  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


  If the polyvinyl alcohol petrochemical hollow paddle dryer meets your requirement, welcome to buy the high quality and durable dryer from our factory. Well acknowledged as one of the leading manufacturers and suppliers of polyvinyl alcohol petrochemical hollow paddle dryer, we must be your best choice. Welcome to enquiry this dryer.
