Product description:<\/strong>
Paddle dryer is an indirect -heating drying equipment, it is suitable to dry good stable materials such as paste, powder, granule and sludge. It is capable of drying material with high moisture and high viscosity. It is characterized by the hollow rotating shafts and the hollow jacket. Copper oxide sludge is a kind of black cake type which is a bit sticky. We copper sludge is fed into the dryer through a screw feeder, and then is heated in the drying chamber in a high heating efficiency. Dry sludge is very fine powder and discharged through the airlock valve under the dryer. Evaporated moisture is taken out of the paddle dryer for dust collection in a bag filter. <\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Applications:<\/strong><\/p>\n

    \n
  1. For drying or cooling powder, small granule, filter cake and slurry materials; particularly good at drying sticky heat sensitive slurry materials continuously.<\/li>\n
  2. Heating area: 1-200m2<\/li>\n
  3. The drying chamber can be vacuum and normal pressure.<\/li>\n
  4. Heat supply can be steam, hot water and hot oil. <\/li>\n<\/ol>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Features:<\/strong><\/p>\n

      \n
    1. Dryer size is minimized, due to the large heat transfer area per volume.<\/li>\n
    2. The wedge shaped paddles goes into the powder to enhance contact to the heat transfer area, and the heat transfer coefficient is relatively high due to the good mixing. So, high heating factor can be obtained. Also, the fullness of the materials is high as 80-90%, therefore large heat transfer area can be efficiently used.<\/li>\n
    3. Since two shafts overlap each other, it prevents the adhesion of powder on the paddle wings, therefore keeping a good heat transfer.<\/li>\n
    4. The residence time distribution is sharp and the powder is uniformly dried.Since the required carrier gas amount is small, the exhaust gas treatment system can also be minimized. This is a big advantage, especially for the closed system with inert gas circulation for solvent recovery.<\/li>\n
    5. Slurry with high moisture content or materials with high viscosity can be treated.Available under
      \nthe vacuumed condition as well, for materials which are sensitive to high temperatures.<\/li>\n
    6. By using oil for the heat medium, it is possible to use high temperature up to 290\u2103.<\/li>\n
    7. Drying and cooling can be done in one unit. <\/li>\n<\/ol>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Technical advantages:<\/strong><\/p>\n

        \n
      1. High heat efficiency: The drying chamber is insulated by 50mm mineral wool and there is very little heat loss via the exhaust gas. The heat efficiency can reach 90%.<\/li>\n
      2. Uniform drying: The specially designed wedge-shaped paddle can completely mix and stir the wet material to achieve very uniform heating. So the drying is very uniform.<\/li>\n
      3. Continuous operation: Thanks to pneumatic ball valves for feeding and discharging under vacuum condition and the rotating paddles which can push the material forward, the drying process can be automatically and continuously.<\/li>\n
      4. High evaporating rate: Under vacuum condition, the boiling point of moisture will be much lower as well as complete and uniform heat transfer, the evaporation rate is much higher than normal paddle dryer.<\/li>\n
      5. Compact size: The drying chamber is very compact in size. Only need small installation space.<\/li>\n
      6. Environment friendly: The evaporated moisture can be recovered by the condenser and buffer tank. The exhaust gas is from the vacuum pump is very little compared to normal dryer.<\/li>\n<\/ol>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

          Product Description\uff1a<\/strong>
          PG Series Continual Plate Dryer is a kind of high effective conducting and continuous drying equipment. Its unique structure and operating principle determine that it has advantages of high heat efficiency, low energy consumption, small occupying area, simple configuration, easy operating and control as well as good operating environment etc.
          It can be widely used in drying process in the fields of chemical industry. Pharmaceuticals, agricultural chemicals, foodstuff, fodder, process of agricultural and sideline products etc. and is well received by various sectors in their practical usage. Now there are three big categories, named normal pressure, closed and vacuum styles; 1200, 2500, 2200 and 3000 size and so on; and three kinds of materials, namely A(carbon steel ), B(stainless steel used for those all part where materials are contacted) and C(on the basis of B to add stainless steel materials for vapor pipes, main shaft and support, and stainless steel linings for cylinder body and top cover).
          With a drying area being from 4 to 180 square maters, now we have hundreds of models of series products and various kinds of auxiliary devices available to meet requirements of drying materials for customers.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

          Working principle:<\/strong><\/p>\n

          The wet material is fed continuously to the first drying layer on the top of the dryer. It will be turned and stirred by rakes when the rake arm rotates and drop down to the outer edge of the large drying plate along the exponential helical line. The material will be moved from the small drying plate to its outer edge and drop down to the outer edge of the large drying plate underneath.
          Both small and large drying plates are arranged alternately so the materials can go through the dryer continuously. The heat medium can be saturated steam, hot water or thermal oil. The heat will be led into hollow drying plates from one end and come out from the other end. The dried materials will drop from the last layer of the drying plate to the bottom of the dryer and then moved by rakes to the discharge outlet. The material moisture will be removed from the exhaust outlet on the top cover.
          For the vacuum-type plate dryer, the moisture will be sucked out by the vacuum pump on the top cover. The dried materials will be discharged from the bottom layer. The drying capability can be improved if the dryer equipped with supplementary devices such as finned heater, condenser for solvent retrieval, bag dust remover, return and mix mechanism, draft fan, and etc.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
