Wedge-Shaped Hollow Paddle Dryer (KJG)

Product Description

It is applicable to indirect heating or cooling the paste, granule, and powder or slurry material. It is a combination unit operation of drying, cooling, heating, sterilizing, reacting or low temperature calcining. This special wedge type processor uses agitator form to develop its higher rates of heat transfer. The wedge-shaped agitator blades are self-cleaning.

The unique hollow, wedge-shaped blades are mounted on a hollow shaft with heat transfer medium flowing through them. This provides a very high ratio of heat transfer surface area to process volume. Heat transfer mediums ranging in temperature from -400C to 3200C can be used. They may be either of the condensing vapor type, such as steam, or of the liquid type, such as thermal oil.

Equipment Features
1. Low Energy Consumption: As the heat flow is indirect, there is no large volume of sweep gas flow through the unit, which is carrying heat away from the dryer. For a slurry, heat requireme -nts may be as low as 1.2kg of steam/kg 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.
