Foodstuff 2M Length Scraper Double Drum Dryer For Potato Flakes
Scraper dryer is an internal heating conduction type rotary continuous drying equipment. The rotating drum passes through the lower chute and adheres to a film of thickness. The heat is transported through the pipe to the inner wall of the drum, to the outer wall of the drum, and then to the feed film, so that the humidity in the film is evaporated and dehumidified. Dry the moisture content of the material. The dried material is placed on the surface of the drum scraper shovel away from the drum to the screw conveyor placed under the scraper, the dry material is concentrated and packaged by the screw conveyor.
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.
