Application of Drum Flaker :
Drum flakers (also known as cooling drums) are used for solidifying molten material. After processing on flakers, the material forms films or easily handled flakes and is further processed or packed into containers for transport. A great advantage of flakers is that they offer a continuous process.
Drum Flaker Working Principle
The hot material is applied to the cooling drum by direct immersion into a trough, or indirect immersion using doctor/applicator rolls. The molten liquid is cooled on the cooling drum and after a partial revolution; the cooled and solidified product is removed by a scraper in the form of flakes or film. The cooling drum of the flaker is specially designed to provide an even cooling effect by having uniform and effective internal distribution. As a result, both high output and homogeneity of the product are possible.
Rotary Drum Flaker Salient Features
- Variable speed drive arrangement for adjustment of the drum speed for optimum performance
- Suitable for a wide range of chemical and pharmaceutical products
- Contact parts can be stainless steel, carbon steel, and hard chrome plated depending on material requirements
- Accessories include hood, flake breaker, flake conveyor, applicator roller etc
There are three designs of Drum Flakers Dryer as below:
1. Dip Feed Drum Flakers Dryer
For products with low viscosity and good adhesion properties a drum flaker with dip pan is used. In this type the rotating drum runs continuously through the heated melt in the dip pan underneath the drum.
2. Overhead Applicator Roll Drum Flakers Dryer
For product with moderate to high viscosity, the overhead applicator roll is used. A heated applicator roll is positioned above the cooling drum. The melt can be easily fed via the trough-shaped nip between the applicator roll and the cooling drum. Contact with the hot applicator roll ensures that the product remains liquid.
3. Twin Drum Flakers Dryer
Drum dryers are of conductive heat-transfer type. A heating medium (generally steam) is sent into the rotating drum (cylinder) and liquid material is fed on the heated drum to evaporate and concentrate, and concurrently the liquid material is stuck on the drum surface in the form of a film, then promptly evaporated and dried. Dried materials are scraped continuously with a stationary knife.
Drum dryers are roughly classified into an atmospheric type and vacuum type according to operating pressures, and also, they are classified into a double drum type, twin drum type, and single drum type according to the number of drums.
Further, the single drum type is classified into a dip type, spray type, splash type, top roll type (single-stage, multi-stage), side roll type, below roll type, etc. according to the liquid feeding methods. These classifications are based on the trial for making materials adhere to the drum surface more uniformly and efficiently.
