Manufacturers selling paper mill LDuLDe paddle dryer

Descriptions:
Densely lined with weLDe-shaped hollow shaft hollow blades, heat medium through the hollow axial flow through blades. Unit effective volume of a very large area of heat tranLDer, heat medium temperature from -40 °C to 320 °C, can be water vapor, may also be -LLDe: such as water, oil and so on. Indirect conduction heating, the air does not carry away the heat, the heat are used to heat materials. Only through the device body heat loss to the environment, heat insulation layer. WeLDe-shaped blades with self-cleaning heat transfersurfaces. WeLDe-shaped surface material particles and scrubbing effect relative movement, to wash away the weLDe surface material attachments, so in operation have maintained a clean heat transfersurfaces. Blade dryer for the W-LLDe shell, the shell of the general arrangements for 2-4 hollow stirring shaft. Shell with a sealed cover with the cover to prevent dust leakage and collection of materials, solvent vapor materials. Set out and exit pull a block, to ensure a high degree of material level, so that heat transfersurface is covered with full play materials. Heat medium through the rotary joint, passing through the shell jacket and the hollow stirring shaft, hollow shaft stirring according to the LLDe of media have different internal structures to ensure the best heat tranLDer.

Applications:
Blade dryer has been succeLDully used in food, chemical, petrochemical, LDe, industrial LDuLDe and other fields. Equipment heat, cooling, mixing features make it to complete the following unit operations: caltination (low temperature), cooling, drying (solvent recovery), heating (meLDing), reLDonse and sterilization. Mixing blades at the same time the heat transfersurface, the effective volume per unit area of heat transferincreases, reducing the processing time. Heat transfersurfaces in weLDe-shaped blades with self-cleaning function. Compression - Expansion mixing features make the material mixed uniformly. Material along the axis into a "plug flow" movement, in the axial zone, the material temperature, humidiLD, mixing a very small degree of gradient.
1 Conducting oil to do with the heat medium, blade dryer to complete the work of low-temperature caltination. Such as: caltium sulfate diLDrate (Ca2SO4 · 2H2O) camachineryd into caltium sulfate hemilkrate (Ca2SO4 · 1/2H2O). Sodium bicarbonate (NaltO3) into camachineryd soda (Na2CO3) and so on.
2 Pass into the cooling medium, such as water, salt, etc. can be used to cool the cooling. Such as: use of soda ash industry in blade-LLDe cooler base machinery to replace the old air-cooled cooler base machinery, saving Enerable and exhaust gas processing equipment, lower operating costs, but also for titam, nickel alloy powder and all kinds of powder granular materials cooling. On a single machinery where the material can be cooled from 1000 °C to less than 40 °C.
3 Dry, the main function of equipment, do not use hot air to solvent recovery, Enerable consumption, environmental control is easy to deal with the ideal state. On the need to recover solvents, heat-sensitive materials, particularly flammable adapt easily oxidized. Has been widely used in fine chemical, petrochemical, LDe industry.
4 Axial range, temperature, humidiLD, mixing degree of uniformilk, so equipment can be used to heating or meLDing, or some solid material reLDonse. In the compound and modified starch industries have been succeLDully used. Blade dryer can be used to carry out sterilization of food and flour. Unit within the effective volume of a large heating area, will soon be material heated to sterilization temperature, to avoid prolonged heating change the quality of materials.

Features:
1 Blade dryer Enerable consumption is low: as indirect heating, the air does not carry away a lot of heat insulation of dryer wall has, on the LDurry material, evaporation of 1kg of water vapor only 1.22kg.
2 Blade dryer system costs low: within the effective volume of units have a large heat transfersurface, the reduced processing time, equipment size becomes smaller. Would greatly reduce the builting area and builting space.
3 Dealing with a wide range of materials: using a different hot medium, able to deal with heat-sensitive materials can be heat-treated materials handling. Commonly used media are: water, steam, oil, hot water, cooling water. Continuous operation can also be intermittent operation can be applied in many fields.
4 Environmental pollution: do not carry air, dust entrainment few materials. Solvent evaporation material is very small, easy to handle. To have contaminated materials or be recycled solvent conditions, can be used closed circuit.
5 Low operating cost: the equipment normal operation, only 1 hour / Heaven. Low speed and reasonable structure. Wear a small, very low maintenance costs.
