Description

Equipment Characteristics

1. Paddle dryer has low energy consumption: Owing to the indirect heating and no air carrying away heat, and the insulating layer installed on the outer wall of drier, for slurry material, to evaporate 1 kg water only needs 1.2 kg steam vapor.

2. Paddle dryer has a low construction cost: As the unit effective volume owns huge heat transfer surface, this will shortens the processing time. The equipment size becomes smaller, thus less building area and space are required for the paddle dryer.

3. Paddle dryer has a wide range material processing: Utilizing different hot mediums can not only process heat-sensitive material but also material requiring to be processed at high temperature. The common mediums utilized are steam, heat conduction oil, hot water, as well as cooling water etc. The dryer can be operated continuously or intermittently. It is widely utilized in many kinds of industries.

4. Paddle dryer has less environmental pollution: Without hot air, there is no material powder dust. The evaporation capacity of material solvent is very small and so it is easy to handle with. For polluted material or solvent required to collect, a closed-system can be applied.

5. Paddle dryer has a low operation cost: When in normal operation, only require one man one hour per day. With low speed agitation and reasonable structure, the equipment wears and tears so little, and the maintenance costs are very low.

6. Paddle dryer has a stable operation: Owing to the special compression, expansion and agitation function of paddle blades, the material grains touch the heat-transfer area thoroughly. Within the axis directions, the temperature, moisture, and mixture grads of the material are very small so as to guarantee the stability of the process.

Applications Field

The paddle dryer has been successfully applied in the industries of food, chemical, petrochemical, dyestuff and industrial sludge etc. The characteristics of heat-transfer, cooling, agitation make it possible to realize the following unit operations: calcining (at low temperature), cooling, drying (solvent collecting), heating (melting), reacting and sterilizing. The agitating blades are utilized as heating surface which increases the heat transfer area of the unit effective volume. The processing time, in most cases, is therefore dramatically reduced. The heat-transfer surface of the wedge paddle blade also has the self cleaning functions. Compression, expansion and agitation functions of paddle blades can mix material uniform distribution. Material flows in axial direction as “plug flow”. The temperature, moisture, and mixture grads of the material are very small within axial range.

1.（Ca₂SO₄·2H₂O）、（Ca₂SO₄·1/2H₂O）、（NaHCO₃）（Na₂CO₃）。Hollow paddle dryer can realize low temperature calcinations by utilizing heat conduction oil. For example dihydrate calcium sulphate (Ca₂SO₄.2H₂O) can be converted to calcium sulfate hemihydrate (Ca₂SO₄.1/2H₂O).Sodium bicarbonate (NaHCO₃) can be converted to pure alkali (Na₂CO₃).

2. By adding cooling medium, such as water, refrigerated brines, the paddle dryer can be utilized for cooling. For example, utilizing paddle soda cooling machine instead of old type air soda cooling machine economize the processing device of energy and tail gas and reduce the operation costs. The paddle dryer can also be utilized to cool titanium, nickel iron alloy powder and all kinds of powder granular materials. Material in single the paddle dryer can be cooled from temperature of 1000⁰C to 40⁰C.

3、Drying, one of the most important applications, without utilizing hot air, can make it in a ideal state to collect solvent, control energy consumption and environment protection. The paddle dryer is especially applicable to solvent collecting, material of easy oxidation, flammable and hot sensitive. The paddle dryer is widely applied in industries of fine chemical, petrochemical, dyestuff, etc.

4、In axial range, the uniformity of temperature, moisture and mixture gradient makes the paddle dryer be utilized to heat, melt or react some solid material. The paddle dryer is applied in fields of compound fertilizer and denaturated starch. The paddle dryer can be utilized to sterilize food and flour. The large heating area within the unit effective volume quickly heat material to the temperature of sterilization. Long heating time which can cause material changes can be avoided.
