*About Jiangsu Fanqun KJG Wedge-shaped Hollow Paddle Dryer
Summary:
Wedge-shaped hollow paddle dryer can indirectly heat or cool the paste, granules and powder or slurry materials. It is a unit integrating the operation of drying, cooling, heating, sterilizing, reacting or low temperature calcining. This special wedge type processor uses agitator form to achieve its higher efficiency of heat transfer. The wedge-shaped agitator blades are self-cleaning. It is one kind of continuous and energy-saved dryer.
There are wedge-shaped hollow paddles in hollow axis, and the heat medium transfers to paddle through hollow axis. The transferring-heat area in a certain volume is large, and the temperature of heat medium is from -40 to 320. The heat medium is steam or hot air or heat conducting oil and so on.
Indirect heating does not consume the energy, so the energy is used for heating material. The energy loss only occurs in heat emission of heat-keeping layer. The wedge-shaped paddles for transferring heat are self-cleaning, which is achieved by the movement between granule shape and wedge-shaped sides. Therefore waste material in wedge-shaped size is cleaned.
The body of wedge-shaped hollow paddle dryer is of W shape. There are 2-4 hollow mixing axes in the body. In order to avoid discharging material dust and collect material solvent, there is a sealed cover on the top of body. A baffle is in the outlet of discharging material in order to keep the height of materials. The heat medium flows to jacket and hollow mixing axis through rotating joint. The hollow mixing axis has different inner structures according to different types of heat medium to ensure the best heat efficiency.
Features:
1. Low Energy Consumption: As the heat flow is indirect, there is no large volume of sweep gas flowing through the unit, which is carrying heat away from the dryer. For slurry, heat requirements may be as low as 1.2kg of steam of water evaporated with a well insulated unit.
2. Low Capital Cost: As the unit has high heat transfer surface to process volume ratios, this shortens the processing time in most cases considerably. The equipment size becomes smaller, thus less building volume is needed for the dryer.
3. A Wide Variety of Processes: Problems can be handled by using any one of a number of heat transfer mediums allowing the unit to be used for certain heat-sensitive materials. The normal heat transfer mediums are 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 kinds of industries.
4. Low Environmental Pollution: Since most applications call for the use of non-carrier gas flow, the vapor steam volume is very low and thus presents a much smaller cleaning problem. Besides its cleanliness, the dryer is often used to convert industrial waste to profitable by-products.
5. Low Operation Expense: Normal operation of that equipment only needs one hour per day of one person. With low speed agitation and reasonable construction, the equipment wears and tears so little, and its maintenance expenses are very low.
6. Stable Operation: Because of the special compression and inflation of agitation function of paddle dryer, the material grains can touch the heat-transfer area thoroughly. Within the axis directions, the temperature, moisture, and mixture grades of the material are very low so as to guarantee the stability of the process.
Application:
The paddle dryer has been already successfully used in the foodstuff industry, chemical industry, petrochemical industry, dyestuff industry and environmental segment, etc. The characteristics of heat-transfer, cooling, agitation make it possible to complete the following unit operations: calcining (low temperature), cooling, drying (solvent recovery), heating (melting), reacting, and sterilizing. The bladed agitator used in the processor is utilized as the heating surface. This increases process volume ratio of the heat transfer surface drastically. The processing time in most cases, is therefore dramatically reduced. The heat-transfer surface of the wedge paddle also has the self cleaning function.
Mixing of process mass locally around the heat transfer surface keeps the semi-plug mass flow so that the temperature and moisture gradients in a specific zone are minimal. (Ca2SO4 2H2O) (Ca2SO4 1/2H2O) (NaHCO3) (Na2CO3). Low temperature calcinations have been accomplished using the paddle dryer. With oil as the heat transfer medium, gypsum (Ca2SO4 1H2O) can be converted to the hemi-hydrate (CaSO4 1/2H2O) and sodium bicarbonate (NaHCO3) can be converted to pure alkali (Na2co3).
