HG Series Double Cylinder Drum Dryer For Potato Starch Powder

The drum dryer consists of a hollow roller with a smoothly polished external surface heated internally by steam.

It rotates on its longitudinal axis. The liquid to be dried is placed in a trough known as feed pan.

The liquid is picked up by the roller as it rotates covering the surface in a thin film is removed mechanically by a scrapper known as doctor knife.

In drum dryer rotates on its longitudinal axis which is heated hallow metal drum , this metal drum is used to dipped in the solution to be dried .

As the dipping process completed the solution on the drum forms as a film on the surface of the dryer and made to dry, to form a layer on the surface of the metal drum. While the drum is rotating the suitable knife which is present just down to the metal drum scraps or peel offs the dried materials from the drum.

Product Working Principle

The drum dryer is a continuous operation device that dries the liquid phase material or ribbon material attached to the outer wall of the cylinder by means of heat conduction through a rotating cylinder. The material liquid to be dried flows into the material receiving tank of the drum dryer from the upper tank. The drying drum is driven by the transmission device, and the material is formed by the filming device to form a material film on the wall of the drum. The cylinder is heated continuously, and the moisture of the material film is vaporized by the heat transfer from the cylinder wall, and the material is scraped off by a scraper, and then conveyed to the storage tank through a screw for packaging. It has high thermal efficiency and can be operated continuously, so it is widely used in the drying of liquid materials or strip-shaped materials, and is more suitable for paste-like and viscous materials.

Product Features

1.High heat efficiency: The heat transfer of the cylinder dryer is heat conduction and the conducting direction keeps identical with operation circle. Most of the heats can be used for evaporation of wet materials on the wall the cylinder. The efficiency can reach 70-80%.
2.Flexible operation elasticity and wide application: Various drying factors of the dryer can be adjusted, such as concentration of the liquid, thickness of material film, temperature of heating medium, rotating speed of the drum, and etc. These factors can change drying efficiency of the cylinder dryer. As these factors have no interrelations each other, it brings great convenience to dry operation and makes it applicable to dry different materials and meet different production requirements.
3.Short drying period: The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials. It also can be pressure reducing operated if it is put in vacuum vessel.
4.Fast drying rate: The thickness of the material film on the wall of the cylinder is very thin. Normal, thickness is 0.3 to 1.5mm. The directions of heat and mass transmittal are identical so the evaporation strength on the surface of material film can be 20-70 kg.H2O/m2.h.

Product Application

This dryer is suitable for drying liquid raw material or sticky material in chemical industry, dyestuff industry, pharmaceutical industry, foodstuff industry, and metallurgy industry, and etc.
