How to Dry Material by Paddle Dryer
Features of the paddle dryer The
wedge-shaped blades have self-cleaning ability to improve the heat transfer of the blade. The dispersing force generated by the combined movement of the inclined surface of the rotating blade and the particle or powder layer automatically removes the sludge attached to the heating ramp, and the blade maintains an efficient heat transfer function. In addition, due to the reverse rotation of the two-axis blades, the alternating section compression (when the two-axis blade faces are close together) and the expansion (when the two-axis blade faces are far apart) the stirring function, the heat transfer is uniform, and the heat is increased. Heat transfer effect.
Hollow Blade Dryer This product can indirectly heat or cool paste, granule, powder and slurry materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction and low temperature combustion. The special wedge-type stirring heat transfer blade in the equipment has high heat transfer efficiency and self-cleaning function of the heat transfer surface.
The paddle dryer is a drying device for the drying of granular materials, which is a synthetic resin, sludge, food, which has been used in a wide range of fields without being bound to, such as chemical drying equipment.
unit operation drying, solvent recovery, heating, sterilization, reaction, cooling, drying under reduced pressure, and the like. Processed products in the form of fine powders, granules, pellets, such as flaky materials, we apply a wide particle size in the shape. In addition, it is a possible high moisture content material, a muddy substance, and a processing viscous substance.
The device is compact due to the large heat transfer area per unit volume. The contact with the wedge-shaped blade of the heat transfer surface is promoted by the effect of biting into the powder, and a large heat transfer coefficient due to the chaotic powder can be obtained. In addition, a high fill rate of 85% to 90% can be used to make the heat conduction area. Adhesion is prevented by the mutual movement of the wedge-shaped flaps overlapping the two shafts, and then pressed. Therefore, the effective heat transfer effect will continue to exist. Narrow residence time distribution without uneven drying.
In a possible operation less carrier gas, facilities such as dust collectors, it needs a small. In particular, a major advantage in solvent recovery is the use of inert gas closed circuits. High moisture content, muddy substances, can also be treated in viscous materials. Because it can also be used for boiling point reduction operation under reduced pressure, it can also be continuous drying, such as weak heat. It is also treated at high temperatures (290 ° C) by using a heat transfer medium for oil. The device is designed to be dried at the same time and can be cooled in a single unit.
