Drum Flakers
Drum Flakers also known as Cooling Drums are used for solidifying various molten materials and are renowned for corrosion resistance and low maintenance. Flakers are mainly used in Pharmaceutical and Chemical Industries and are designed in different specification. The main benefit of Flakers is that they offer a continues process. Some drum flakers are rotary drum flakers, single drum flakers, double drum flakers, cooling drums flakers etc.
Operating Principle of Drum Flaker:
The hot material is applied to the Drum Flakers (cooling drum) by direct captivation into a trough, or indirect captivation using doctor/applicator rolls. The soften 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 flake or film. The cooling drum of the Flaker is especially designed to provide an even cooling effect by having consistent and effective internal distribution.
Rotary Drum Flakers
Rotary Drum Flakers consist of a cylindrical drum having provision for cooling drum surface. One end of the drum shaft is connected to a gear box which is driven by a motor. The heating cooling media will be circulated in drum during operations, the drum rotates at a slow speed. A thin layer of the product to be dried / cooled, adheres to the outside of the rotating, drum and internally cooled drum. The product gets solidified and is after an almost complete rotation, scrapped off drum surface and at the same instant granulated in the form of flakes, falls on screw conveyor. At the bottom of conveyor, filling point is provided to fill the bag. The entire process is continuous operation, does not require manpower except bag filling. Pneumatic / hydraulic operation of scraper assemblies can be provided.
Features of Rotary Drum Flakers:
Continuous type Dryers and Coolers
Suitable for solid separations from liquids without filtration operation
Bigger solid particles / Flakers
Suitable for sticky materials, Resins, Snacks, food Fine chemicals
Direct air heated, Hot water, Steam or Electric heater
