Sludge Dewatering Hollow Paddle Sticky Material Dryer Equipment

Hollow paddle dryer is a horizontal agitating dryer based on heat conduction. Because the inner hollow agitating blade is shaped like a paddle, it is called a Hollow paddle dryer. The paddle dryer has been developed abroad for many years. This type of machine has developed two-axis and four-axis structures and multiple specifications in foreign countries. The paddle dryer was first developed by Germany. After that, the technology was introduced in Japan and improved. Two-axis and four-axis structures and more than ten specifications were developed. Since the heat required for drying the device is indirectly heated by heat conduction, the drying process requires only a small amount of gas to carry away the moisture, which greatly reduces the loss of heat that is carried away by the gas and improves the utilization of heat. Rate, strength drying Hollow paddle dryer is an energy-saving drying device. It can indirectly heat or cool the paste, granule, powder, and slurry materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature calcination.
