Calcium sulphate chemical hollow paddle dryer


  Calcium Sulfate Chemical Hollow paddle project description:
  Calcium sulfate, white monoclinic or crystalline powder. No smell. Hygroscopicity. Soluble in acid, sodium thiosulfate and ammonium salt solution, dissolved in hot water less, very slowly soluble in glycerol, insoluble in most organic solvents. Irritating. Usually contains two crystal water, nature in the form of gypsum mine. Jiangsu Jianda Dry Engineering Co., Ltd. is studying calcium sulfate drying, our company developed the calcium sulfate dryer is your best choice.


  First, calcium sulphate chemical hollow paddle dryer principle:
  There are wedge-shaped hollow paddles in hollow axis,and heat medium is from-40oC to 320oC, the heat medium is steam or hot air or heat conduction oil and so on. Indirectly heating way does not take the energy, so the energy is used for heating material. The energy loss is only heat emission of heatkeeping layer. The transferring heat of wedge-shape side takes cleaning actions. It can clean waste material in wedge-shaped size.The body of wedgeshaped hollow paddle dryer is W shape.


  There are 2-4 hollow mixing axes in the body.In order to avoid discharging material dust and to collect material solvent, there is a sealed cover on top of body. A baffle is on the outlet of discharging material, in order to keep the height of materials. 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 transferefficient.


Second, calcium sulphate chemical hollow paddle dryer characteristics:

  1. Low energy consumption, as the heat flow is indirect, there is no large volume of sweep gas flow through the unit, which will carry heat away from dryer.Take slurry as example, heat requirement maybe as low as 1.2kg of steam/kg for evaporating 1kg water in hollow paddle dryer.

  2. Paddle dryer system low cost: the unit effective volume has a huge heat transfer surface, to shorten the processing time, equipment size smaller. It greatly reduces the construction area and building space.

  3. Wide variety of process problems can be solved by using any kinds of heating source. It is specially suitable for drying heat sensitive materials and ligh temporature materials.The normal heat transfer medium can be steam, heat transfer oil, hot water, as well as cooling water etc…The dryer can be used for continuous or batch processing. It has been widely used in many industry areas already.


  If the calcium sulphate chemical 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 calcium sulphate chemical hollow paddle dryer, it is your best choice.
