タイトルまたは説明

With more than *0 years’ experience, Changzhou Hengbo Machinery CO., Ltd. designs and manufactures paddle dryer of good quality and good price. The paddle dryer is utilized for indirectly heating or cooling the materials of paste, granule, powder or slurry. The paddle dryer can realize the unit operation of drying, cooling, heating, sterilizing, reacting or calcining at low temperature. This special wedge type agitating blades possess higher rates of heat transfer and functions of self-cleaning.

The unique wedge-shaped hollow paddle blades are closely mounted on a hollow shaft. The hot medium flows through hollow shaft to paddle blades. The heat transfer area within the unit effective volume is very large. The hot medium, which the temperature is from ***0C to ***0C, can be either steam vapor or liquid type, such as hot water or heat conduction oil. With indirect conduction heating, no air carrying away heat, the heat is utilized for heating material. The heat loss only refers to the heat dissipation through the heat insulation layer of drier to the environment. The heat transfer surface of wedge-shaped paddle blade owns self-cleaning functions. Washing and brushing functions caused by the relative movement from material particles and wedge-shaped surface can wash off the attached material on the wedge-shaped surface so as to keep a cleaning heat transfer surface during the paddle dryer running. The shell of hollow paddle dryer takes the shape of W. There equipped with two to four hollow paddle shafts inside the shell. The shell has sealing end cover and upper cover in preventing powder dust leakage and collecting the steam from material solvent. A baffle plate is installed at material discharging outlet to ensure the height of material level so that heat transfer surface is covered with material fully. The heat transfer medium flows through the shell jacket and hollow agitating shafts through rotary joint. The hollow agitating shafts have different internal structures according to types of hot medium to ensure optimal heat transfer effect.

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.
