Where are the advantages of vacuum disc dryer compared with vacuum harrow dryer?

Compared with vacuum harrow dryer, the main advantages of vacuum disc dryer are as follows:

1、Material mechanical conveying, continuous production, adjustable capacity. Avoid the heavy loading and unloading materials and artificial disc work, light labour intensity, good labour conditions, convenient management.

2、High drying efficiency, the total heat transfer coefficient can reach 240-544kJ/(m.2h.℃), the average evaporation intensity of about 7-25kg/(m.2h).

3、Vertical installation, perfect heat preservation, high utilisation rate of heat source and waste heat. Evaporation of each kg of water only 11-1.4kg steam. In addition, the power required is only about 1/10 of rotary cylinder dryer, economically feasible.

4, covers an area of small, compact structure, equipment installation is simple, indoor and outdoor can be used on the spot.

5, the exhaust gas or steam exhaust mountain speed is low, less dust flying, can meet the three waste emission standard requirements, improve the labour environment. For the drying of pesticide raw material is particularly suitable, and do not have to be attached to the dust removal equipment.

6, the number of heating discs and spindle speed adjustable, the material in the dryer can be freely selected according to the requirements of the process.

7, the temperature of each layer of material disc can be controlled to achieve the specified temperature distribution. Drying and cooling together, can obtain the quality of uniform, small machine city stress of dry products.

8、Equipment components standard generalisation, according to the requirements of the working conditions of the assembly, adaptability.

9, if appropriate combination with other equipment, can also recover solvents and dry paste materials. Can also be used with roasting, sublimation and other products thermal processing.
